The best open source software 2018 | TechRadar

The term open source refers to software whose source code is freely available to download, edit, use and share. There are different open source licenses, which give users different degrees of freedom, but the main aim of open source is to encourage collaboration.

Open source software has lots of advantages over other free options youll come across even if youre not a developer yourself. Its usually maintained by a community and updated frequently to patch vulnerabilities or squish bugs as soon as theyre identified; there are no restrictions on commercial use, so you can happily use it for your home business; and the ability to edit the source means theres often a wealth of user-created plugins available to download.

With that in mind, here’s our pick of the very best open source software.

There’s no need to pay for Office with this open source alternative

LibreOffice is a full suite of office software, including excellent apps for text documents, spreadsheets, presentations, and databases. These are all fully compatible with the latest Microsoft file formats, so youll have no trouble sharing files work users of Word, Excel, PowerPoint, and Access.

Documents look just as sharp and professional as those created using paid-for software, and there are hundreds of templates available to download, use and edit.

LibreOffices huge community of contributors have compiled a brilliant collection of support materials, including a forum and even live chat if you need a hand.

Even if you have the ready cash for an audio editor, you might choose to stick with open source alternative Audacity. It has almost all the tools you need for recording and refining sound files, and any features it lacks can be plugged with its extensive catalog of extensions.

Audacity is the tool of choice for many podcasters, musicians and audiobook narrators thanks to its professional quality results. You can use it to combine clips, copy and paste sections of audio, remove noise and other unwanted noises, strip vocals from songs, alter frequencies, and apply effects like echo and reverb.

An powerful, fully customizable browser with a plugin for every purpose

The browser wars show no sign of ending, but Firefox’s open source heritage makes it incredibly flexible. Its main appeal is its collection of extensions. With thousands of plug-ins available at the click of a mouse, its easy to transform Firefox into your perfect browser.

Firefox is updated every five to eight weeks, and you can get an early taste of the latest features by installing the beta or taking part in Firefox Test Pilot a way to sample experimental tools that might be incorporated into future releases.

Firefoxs source code forms the basis of many specialist projects, including the security-focused Tor Browser and speed-centric Waterfox, which is designed with power users in mind.

A free client that’s an ideal replacement for the defunct Windows Live Mail

If you have multiple email accounts even if theyre with the same provider open source email client Mozilla Thunderbird will save you time and hassle flicking between browser tabs and logins. Like Firefox, Thunderbird is an open source project published by the Mozilla Foundation, and is almost infinitely adaptable.

Thunderbird’s standard features include an RSS reader and the ability to link to files too large to send as attachments, and its optional extras include weather forecasts and Google app tabs.

Open Source Mac – Free Mac software, all open-source, all …

Free and open-source software is good for you and good for the world. This is the best free Mac software that we know of.

Open Source Mac is a simple list of the best free and open source software for Mac OS X. We aren’t trying to be a comprehensive listing of every open-source mac app, instead we want to showcase the best, most important, and easiest to use. This page should be a handy reference and a useful tool for getting more people to start using free and open-source software. If you think we’re missing any great apps, please let us know. Open Source Mac is of course hosted on Linux.

Note to software creators: first of all, thanks so much for making free, open-source software– we love you.

Second, if we linked to macupdate or versiontracker as the download page, it’s because we think your download page is too confusing for new users. It’s usually very easy to improve– just add a big ‘Download Now’ link towards the top of the page, without too much clutter around it (use mozilla.org or adiumx.com or bittorrent.com for inspiration).

Here’s some more unsolicited advice for getting more people to download your software:

a. if you have a nice icon, show it off prominently.

b. put a download link and a screenshot on your front page.

c. if you use mirrors, use a script to pick a random mirror and just give people one link that says ‘download now’

d. if there’s any way you can avoid sending people to the sourceforge download mirror page, you should (we know it’s not your fault, but it baffles lots of folks).

e. if you really want to make things easy for people, and you have a cross-platform app, detect what OS they are on and give them the correct link.

f. test your page on a novice! See if they can understand what the software does and how to get it.

Comparing Open Source vs Closed Source Software

Youre no technical guru and have been charged with finding a web content management system (CMS) for your business. Simple right?

So are you after anOpen or Closed source CMS?Um…Im looking to update my content multiple times a week to benefit our SEO and engage our audience beyond traditional marketing methods?Yes, ok. But are you looking for an Open Source CMS or a Closed Source CMS?Um. Im not really the technical guy…

Theres no need tobe intimidated by this technical jargon. The differences between Open and Closed source software are fairly straightforward and there are fairly clear pros and cons for each. There is no right or wrong answer to the question either. Your best option will largelydepend on your business and itsgoals. In the end, the main objective is to have access to aCMSthat iseasy for you and your team to manage on a day to day basis.

But lets start with a few basics to help you get in the conversation.

Open source software (OSS) is distributed under a licensing agreement which allows computer code to be shared, viewed and modified by other users and organizations.

Or in slightly more user-friendly language, open sourcesoftwareis available for the general public to use andmodify from its original design free of charge. What it means is that a piece of software can evolve and be iterated upon by otherdevelopers anywhere in the world. Ideally, this means that the software is improved over time, but it can often take plenty of interesting twists and turns with all of that evolution and canchange form and shape entirely.

Open Source feels inherently cool and well…open. In theory, it feels like what the Internet was supposed to be all about. But it should also comewith a warning label.Theres a fantastic fortnightly podcast about technology that I never misscalled Reply All. They ran an episode recently called Disappearedthats really worth a listen.

It delvesinto the idea of the open web and theprinciples of self-governance that drivethe ethos of open source software. Whilst an openand peer to peer oriented web is to be applauded philosophically, it can leave usvulnerable to rogue developers who choose to break things for their own benefit. Hence the need for a warning label.

Closed source software can be defined as proprietary software distributed under a licensing agreement to authorized users with private modification, copying, and republishing restrictions.

Or in layman terms, thesourcecode is not shared with the public for anyone to look at or change.Closed sourceis the opposite of opensource. Thanks Wikipedia 😉

Closed source is actually the sort of arrangement that you would expect from most businesses, protective of their product and keen to maintain control over their brand and the user experience offered to their customers. Think Apple rather than Android.

So, when considering open source or closed source (proprietary) software, what are some of the key differences to take into account before making a decision? We’re goingto take a look at service/support, innovation, usability and security in both open source and closed source software and outline the pros and cons of both software systems.

Generally, the key differentiators between open and closed come down to a few factors:

There are pros and cons of each and the direction you head in, will largely depend on your priorities for each of these 5 factors. Those priorities will help dictate when its appropriate to use open source and when to use a closedsource CMS.

One of the main advantages of open source software is the cost; however, when applied to OSS, the term “free” has less to do with overall cost and more to do with freedom from restrictions.

If you have the in-house capabilities and technical expertise to maintain the software, and resources to implement, train and provide support to staff, then open source may be most cost-effective for your organization. You should consider, however, the long-term costs of implementation, innovation, providing support, and investing in infrastructure as your company evolves, technology changes, and your needs grow.

** Update we recently took a detailed look at the costs of platforms with our postDo You Know The True Cost of Managing a Website?It will help you understand what are the true costs.

Open software providers are also increasingly charging for extras like add-ons, integration, and additional services, which can negate any cost-saving advantages in some cases. In the end, rather than being free, you are still paying for a service with open source software.

For a Closed Source CMS, depending on the complexity of the system, thecost can vary between a few thousand to a few hundred thousand dollars, which includes a base fee for software, integration and services and annual licensing/support fees. While the hard cost can be higher, what you get in return is a more customized product from a trusted brand, higher levels of security and functionality, continuous innovation, greater scalability, ongoing training and support and a lower requirement for technical skills.

Open source software relies on a loyal and engaged online user community to deliver support via forums and blogs, but this support often fails to deliver the high level of response that many consumers expect (and can receive with proprietary software).

These communities must also be found on the web and some would argue there is no incentive for the community to address a user’s problem.

Service and support are probably the greatest advantages of using proprietary software (closed). Ongoing support is a key selling point for users with little technical skills and one of the main reasons people choose closed source over open source software.

Support includes user manuals and pointsof contact for immediate assistance from viable companies with experts who are intimately familiar with the products and services

Open source software provides a large amount of flexibility and freedom to change the software without restriction. This innovation, however, may not be passed on to all users and it is debated whether customized changes to the original source code can limit the future support and growth of the software. Once more, open source software providers often struggle to attract large-scale research and development.

Some see the inability to view or change the source code in closed source software as a drawback when compared to the unrestricted flexibility of open source; however, this restriction ensures the security and reliability of proprietary software that is fully tested and offered to all users.

Once more, customized software is available for specific users. Unlike open source, proprietary software also attracts larger amounts of R&D in order to regularly offer new products and upgrades.

Like open source software, closed sourcesoftware also has dedicated online communities that share ideas and strategies through forums and surveys, fostering innovation and allowing the product to adapt with changing needs.

Usability is often a major area of criticism for open source software because the technology is generally not reviewed by usability experts and caters to developers rather than the vast majority of layperson users. User guides are not required by law and are therefore often ignored. When manuals are written, they are often filled with jargon that is difficult to follow.

For closed or proprietary software, usability is a high selling point (think Apple again) due to expert usability testing for a more targeted audience. User manuals are also provided for immediate reference and quick training, while support services help to maximize use of the software. Third party systems and developers are also able to use a variety of mechanisms to enhance “closed” source software.

Security of open source is often a concern for large companies because software is not always developed in a controlled environment.

With individual users all around the world developing the software, there is a lack of continuity and common direction that prevents effective communication. Once more, the software is not always peer-reviewed or validated, meaning that a programmer can embed a backdoor Trojan into the software while the user is none the wiser.

One way to reduce this potential risk is to adopt a reputable brand with a concentrated development team supported by a strong online community.

Proprietary or closed software is generally seen as more secure because it is developed in a controlled environment by a concentrated team with a common direction. This team is the only group that can view or edit the source code, it is heavily audited and the risk of backdoor Trojans or bugs are reduced (though no security can be flawless).

The keypros and cons of open vs closed source softwarelargely depend on your technical expertise and resources available to maintain and update the software. Consider the five points outlined in this article to get a better idea of the right software for your company’s needs now and in the future.

Best Open Source Software for Windows 10 – Datamation

I’ll be the first to admit that I’m not a huge Windows fan. That said, I work with many folks who are. Which gets me thinking about open source applications that would be a best fit for their Windows 10 installations. In this article, I’ll share my top picks for Windows 10 open source software.

Hey, just because someone is using Windows doesn’t mean they can’t still enjoy the benefits of great open source software! Right?

When it comes to backing up your DVD collection, in case of fire/kids/life, it’s tough to beat the awesome feeling that comes from a completed Handbrake session. Despite its highly customizable nature, Handbrake also provides you with some helpful presets to make the disc to file conversion as painless and simple as possible. I personally appreciate the preview mode myself.

Whether you’re still using traditional FTP to upload your files to a server or keeping it secure with SSH keys using sFTP FileZilla has you covered. I’ve long believed that FileZilla is among the best in class FTP management applications on any desktop operating system. You can drag drop, change permissions, even master through thousands of batch transfers without breaking a sweat!

Despite statements to the contrary, podcasts are not dead. Many of the most popular are booming right now and you can use Juice to capture all of your favorites, automatically. Thanks to the magic of RSS enclosures, your favorite podcasts can simply appear on your PC as they’re released. Not sure what to listen to? No biggie, they have a huge directory of podcasts to choose from. How’s that for convenience?

When I watch video on a PC, I run VLC. To me, it doesn’t matter if that PC runs Windows or Linux, my expectations on what I want from my video player are the same. As a general rule, VLC will play just about anything. VLC works like a champ for anything audio- or video-based, ranging from FLAC audio to DVD playback.

It often amazes me how frequently I find myself relying on GIMP these days. From image combining to extraction, GIMP is simply one of the best tools in my toolbox. Admittedly, I’ve used it for so long that using anything else is out of the question. I have a workflow that works for me and GIMP is at the forefront of any serious creative project I have to accomplish.

I’ve found that many people who honestly don’t know anything about running Open Source software are, in fact, running a fairly current version of LibreOffice. Usually these individuals read about it somewhere, found it for free or had it installed by someone they knew. The one common thread all of these folks seem to share is the fact that it’s being used often and dependably. Whether I’m running calculations with Calc or word processing with Write, these are my goto apps within the LibreOffice suite. Impress for presentations is also fantastic and worth your consideration.

The very first time I switched to an open source jukebox media player for my music, I ended up with amaroK on Linux. Years later, I’ve found myself using a fork of this media player called Clementine. It offers the best features anyone could want in a music player. I’ve been known to plugin to my Spotify account and export my playlists. This way if I ever switch to something different, say Google Play Music, my playlists will remain intact. That is the power of Clementine, folks.

Very few applications have shook my view of using Windows harder than Notepad++. Suddenly I find myself using a sane, usable text editor that doesn’t leave me frustrated! In my humble opinion, its the most amazing text editor ever conceived of for Windows users. Notepad++ features a tabbed interface with macro support, customizable GUI, Perl Compatible Regular Expression Search/Replace, and zoom functionality. Bundle all this with its syntax handling and you’ll never want to close this editor!

Most people don’t think much about the licensing of the VM software they use. But if you’re using VirtualBox OSE, you could be using the Open Source Edition to boot another OS within your host Windows installation. Side note, I like to think that using VirtualBox is a great way to get to know Linux…without any lengthy commitment!

Trying to track down large files that are stealing precious hard drive space can be a pain. But Windows users rejoice, there’s an app that can help you with this challenge WinDirStat. Designed to be a visual application, WinDirStat will literally show you which files and directories are taking up the bulk of your hard drive space. To make things easier, you’ll also find that WinDirStat provides pretty solid tree-map support as well.

Not to be confused with Woz, the co-founder of Apple, Wox is a keyboard launcher designed to make you more productive at your Windows computer. For me, I can’t even fathom using a computer without a good keyboard launcher. So if you were to drop me in front of a Windows box today, I’d be using Wox without a second thought. Using Wox, I can search the Web, locate files to open, and even startup programs!

Automating Macros and repetitive tasks can be a real pain. Lucky for you, there’s an open source application called AutoKey to take the sting out of the experience. Even with documentation, there is a learning curve involved, yet once you get the hang of it you’ll never look back. At it’s simplest, you can think of AutoKey as software designed to automate keystrokes and mouse clicks. You can even use it to help with typing. For example, abbreviations can become full sentences or paragraphs. It’s actually pretty amazing what can be done with this application.

Gone are the days of taking screen shots only to drop them into some paint like program! With Greenshot, you can take a screenshot and then add annotations, or even export a screenshot straight to a printer. Need to highlight or obfuscate parts a screenshot? Not a problem! Only wish to take a screenshot of a region of the screen? Again, this is doable without any issues. Greenshot is a must have application for Windows.

So which open source applications are you using? Perhaps you’re using them on other platforms like Linux or OS X? No matter, hit the Comments and sound off with your favorites! I’d love to compare notes and see if there are any new software titles I haven’t heard of.

Open Source Software | American Libraries Magazine

Open source software is a key option libraries should consider when implementing strategic technologies. Even though a greater number of libraries are adopting proprietary systems, open source products provide a viable alternative and exert competitive pressures, both in cost and innovation.

Integrated library systems (ILS), as well as the new genre of library services platforms, are offered to libraries primarily as proprietary products controlled by a single vendor. Libraries that use these products remain dependent on that vendor for ongoing software development, solutions to systemic problems, and service enhancements. While proprietary software remains the dominant approach, a growing percentage of libraries are adopting open source products. In fact, libraries with open source integrated systems report the same levels of satisfaction as those using proprietary products, according to the Perceptions 2016 survey on library automation.

Open source systems have been part of the overall automation landscape for more than 15 years and have become a well-established and mature option. Open source software principles are well understood, as are the relative advantages and disadvantages of its development models and support arrangements. The August/September 2017 issue of Library Technology Reports discusses some of the processes of software development, implementation, and support. Open source ILS products, such as Koha and Evergreen, have cultivated vibrant and well-coordinated communities that work diligently toward the continued enhancement and support of these products.

Open source initiatives encourage for-profit companies as well as nonprofits to become involved.

Open source projects generally involve collaborative development processes, where companies and individuals work together out of mutual interest to create and improve a product. This joint effort requires a robust communications process and effective tools. Most open source software development projects make use of several types of collaborative tools:

Open source initiatives often encourage for-profit companies as well as nonprofit organizations to become involved. While open source projects do not involve license fees, they provide many other opportunities for companies to provide services for which they can charge fees. For example, many companies have become involved with Koha, the most widely implemented open source ILS in the world. Technology revenues are increasingly derived from services than from direct sales of software licenses. Service fee categories include:

Self-support for open source ILS products is relatively uncommon in the US, where libraries mostly engage with commercial support firms. Implementation in partnership with a commercial support provider requires no more in-house technical expertise than a proprietary product.

Open source today falls well within the mainstream of technology options. Evergreen and Koha have matured and offer functionality comparable with many proprietary products. The FOLIO project promises to create a new library services platform based on a modular design and the microservices architecture.

Main Did You Know Computer_Science Updated April 10, 2014 / Posted September 26, 2008

By Vangie Beal

We discuss open source software, the basics behind the Open Source Initiative (OSI), and Free Software Licensing.

Open source refers to a program or software in which the source code (the form of the program when a programmer writes a program in a particular programming language) is available to the general public for use and/or modification from its original design free of charge. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community.

The rationale for this movement is that a larger group of programmers not concerned with proprietary ownership or financial gain will produce a more useful and bug-free product for everyone to use. The concept relies on peer review to find and eliminate bugs in the program code, a process that commercially developed and packaged programs do not employ.

The basics behind the Open Source Initiative is that when programmers can read, redistribute and modify the source code for a piece of software, the software evolves. Open source sprouted in the technological community as a response to proprietary software owned by corporations.

Proprietary software is privately owned and controlled. In the computer industry, proprietary is considered the opposite of open. A proprietary design or technique is one that is owned by a company. It also implies that the company has not divulged specifications that would allow other companies to duplicate the product.

Open Source is a certification standard issued by the Open Source Initiative (OSI) that indicates that the source code of a computer program is made available free of charge to the general public. OSI dictates that in order to be considered “OSI Certified” a product must meet the following criteria:

Open source software is normally distributed with the source code under an open source license. The Open Source Initiative sets the following distribution terms that open-source software must comply with;

Open source doesn’t just mean access to the source code. The distribution terms of open-source software must comply with the following criteria:

The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.

The program must include source code, and must allow distribution in source code as well as compiled form. Where some form of a product is not distributed with source code, there must be a well-publicized means of obtaining the source code for no more than a reasonable reproduction cost preferably, downloading via the Internet without charge. The source code must be the preferred form in which a programmer would modify the program. Deliberately obfuscated source code is not allowed. Intermediate forms such as the output of a preprocessor or translator are not allowed

The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.

The license may restrict source-code from being distributed in modified form only if the license allows the distribution of “patch files” with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software.

The license must not discriminate against any person or group of persons.

The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

The rights attached to the program must apply to all to whom the program is redistributed without the need for execution of an additional license by those parties.

The rights attached to the program must not depend on the program’s being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program’s license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.

The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open-source software.

No provision of the license may be predicated on any individual technology or style of interface.

[Source: Open Source Initiative, “The Open Source Definition”]

All open source software is not distributed under the same licensing agreement. Some may use a free software license, a copyleft, or GPL compatible. The GNU GPL license is a free software license and a copyleft license, while a “GNU Lesser General Public License” is a free software license, but not a strong copyleft license. There are many different types of licenses for free software . some GNU GPL compatible, some not.

The Open Source Initiative approves open source licenses after they have successfully gone through the approval process and comply with the Open Source Definition (above). There is currently well over fifty licenses that have been approved by the OSI.

For example, the GNU General Public License (GPL) is one license that accompanies some open source software that details how the software and its accompany source code can be freely copied, distributed and modified. The most widespread use of GPL is in reference to the GNU GPL, which is commonly abbreviated simply as GPL when it is understood that the term refers to the GNU GPL.

One of the basic tenets of the GPL is that anyone who acquires the material must make it available to anyone else under the same licensing agreement. The GPL does not cover activities other than the copying, distributing and modifying of the source code.

Other open source licenses include the following:

[Source: You can read the details and newly added approved licenses on the OSI Open Source Licenses Web page]

A software programmer really has his or her own reasons for contributing to open source projects. Some may just be looking for fun or a challenge, while others are looking to improve skill and build on their programming abilities, or they may want to belong to a group project. In many instances there is the opportunity to make money as open source projects can be funded by government or corporate sponsors. Unlike commercial projects, open source projects allow the programmer’s name to be known, which benefits a programmer’s name and portfolio which can lead to future jobs with other funded open source or commercial projects.

The hype and benefits of open source has not gone unnoticed in the commercial world where some corporations have jumped on the open source bandwagon. Since commercial software is sold for profit, one may wonder why a company would be interested in open source projects. In many cases companies are able to profit through selling add-on tools or modules, or paid consulting services and technical support for the program.

Sendmail is an open source mail transfer agent (MTA) used for routing and delivery e-mail. The original version of Sendmail was written by Eric Allman in the early 1980s. It is estimated that Sendmail is installed on 60 to 80 percent of the Internet’s mail-server computers.

Often referred to as simply Apache, a public-domain open source Web server developed by a loosely knit group of programmers. The first version of Apache, based on the NCSA httpd Web server, was developed in 1995. Core development of the Apache Web server is performed by a group of about 20 volunteer programmers, called the Apache Group. However, because the source code is freely available, anyone can adapt the server for specific needs, and there is a large public library of Apache add-ons.

(Pronounced lee-nucks or lih-nucks). A freely distributable open source operating system that runs on a number of hardware platforms. The Linux kernel was developed mainly by Linus Torvalds. Because it’s free, and because it runs on many platforms, including PCs and Macintoshes, Linux has become an extremely popular alternative to proprietary operating systems.

Acronym for GNU Network Object Model Environment. (Pronounced guh-nome) GNOME is part of the GNU project and part of the free software, or open source, movement. GNOME is a Windows-like desktop system that works on UNIX and UNIX-like systems and is not dependent on any one window manager. The current version runs on Linux, FreeBSD, IRIX and Solaris. The main objective of GNOME is to provide a user-friendly suite of applications and an easy-to-use desktop.

open sourceGenerically, open source refers to a program in which the source code is available to the general public for use and/or modification from its original design free of charge, i.e., open.

GPLShort for General Public License, the license that accompanies some open source software

GNUSelf-referentially, short for GNU’s not UNIX, a UNIX-compatible software system developed by the Free Software Foundation (FSF).

LinuxPronounced lee-nucks or lih-nucks. A freely-distributable open source operating system that runs on a number of hardware platforms.

GNOME Acronym for GNU Network Object Model Environment. (Pronounced guh-nome.) GNOME is part of the GNU project and part of the free software, or open source, movement.

Did You Know… The Open Source Definition was written by Bruce Perens as “The Debian Free Software Guidelines”, and refined it using the comments of the Debian developers in a month-long e-mail conference in June, 1997. He removed the Debian-specific references from the document to create the “Open Source Definition.”

Open-Source Software Won’t Ensure Election Security – Lawfare (blog)

The technology behind elections is hard to get right. Elections require security. They also require transparency: anyone should be able to observe enough of the election process, from distribution of ballots, to the counting and canvassing of votes, to verify that the reported winners really won. But if people vote on computers or votes are tallied by computers, key steps of the election are not transparent and additional measures are needed to confirm the results.

In a New York Times op-ed a couple weeks ago, James Woolsey and Brian Fox proposed using “open-source systems that can guard our votes against manipulation.” Their hypothesis is that “open-source software is less vulnerable to hacking” than proprietary voting software because “anyone can see how open-source systems operate. Bugs can be spotted and remedied, deterring those who would attempt attacks. This makes them much more secure than closed-source models.” This sounds reasonable, but in fact, open-source systems are only one step towards guarding our votes against manipulationand the hypothesis that using open source software willby itselfimprove security is questionable at best.

First, with the systems in use today, there is no guarantee that the software running on any machine is in fact the software it is supposed to be running, open source or not. And even if we could know with certainty that the installed software matches the software source, the quality of the software is critical. Poorly written software, whether open source or not, creates vulnerabilities, and is thus vulnerable to hacking. Open source software allows anyone to detect vulnerabilities. We do not believe in “security through obscurity”that is, relying on secrecy as a primary security strategybut making source code available to everyone for inspection makes it available to the attackers for inspection. And the attackers are often highly motivated to find vulnerabilities.

Complicating this is the relative ease of identifying one vulnerability and the difficulty of finding them all. Attackers need to find just a single flaw in order to exploit a system. On the other hand, it is very easy for reviewers to miss somethingthe Heartbleed bug that affected millions of websites and devices in 2014 occurred in open source softwareor to make assumptions about the environment in which the source code is executed that turn out to be wrong. Software authors, maintainers, election officials, and other defenders must find every flaw, fix them all, and then distribute the fixed system (or patches) to everyone using the system.

Patch distribution creates its own set of potential problems, as it informs attackers that there was a vulnerability (and where in the code it is), leaving anyone who does not immediately install the patch especially vulnerable. For example, many years ago, a response group announced a patch to a well-known, widely used piece of software. Within thirty minutes, that vulnerability was being exploited around the world. Many sites did not have the time or resources to install the fix. The patch was announced at 5 p.m. East Coast time on a Friday, making things worse.

Open source software is a good thing. Published source, a lower bar, is a useful if less optimal alternative. But visibility of the source is not enough. Security analysts need access to everything that is used to create the system, including operating system source, driver source, compiler source, hardware, and hardware fabrication information, and then directions on how to create the systems used in the voting (such as the voting system, the tally system, and any systems and software used to display the results). Even that isn’t enough, as (for example) the fabrication facilities may not follow the directions the analysts are given. The supply chain matters, toomanufacturers or their employees may even be malicious! So the analysts need to monitor the actual system construction to verify everything. Even then, they must be aware that what is done today may not be what is done tomorrow, or what was done yesterday.

Finally, even perfect software does not guarantee trustworthy elections. Trustworthiness is also a product of the way the system, and software, are used. For example, consider a system that uses a difficult-to-guess password, but that password can be found on a website. No amount of scrutiny of the system will reveal this flaw.

So assuming that open source systems are more secure than other systems is a dangerous fallacy, just as assuming closed source systems are more secure than other systems. Properly evaluating security requires more than simply considering the openness of the source.

The question we should be asking is “how can we ensure that election results are accurate when we cannot trust the computers used to run elections?” rather than “how do we make electronic voting secure?” Nothing is ever absolutely secure. But we can often make computers, systems, and processes “secure enough” for their tasks, provided we have an independent way to check the results. One technique is to produce a voter-verified paper trail, ensure that the paper trail is trustworthy, and manually audit the electronically tabulated results against the paper audit trail. Another technique called “end-to-end verifiability” allows individual voters to verify that their vote was recorded and counted correctly. Simply enabling everyone to examine the source is not sufficient, and could even give voters and election officials a belief that the system is secure when it is not.

We believe there are excellent reasons to move to open-source voting systems. For instance, there are good arguments that the public should own the voting system. Open-source systems allow vendor claims about software to be verified. Open-source systems running on commercial, off-the-shelf (COTS) hardware could be far cheaper to acquire and maintain than proprietary voting systems. Adopting open-source systems could promote a competitive market for technical support for local election officials, also decreasing costs. Open-source systems could be designed to facilitate auditing against the paper trail more efficiently than commercial systems permit. And using open-source systems would make it possible for jurisdictions to customize the software to their needs.

All this needs to be considered as we work to improve the security and transparency of our election systems. But adopting open-source systems would not by itself provide any assurance that computers used in voting are doing what they are supposed to do. Nor would it obviate the need to audit the results.
