Prior to GitHub, Mike was the Vice President of Security at Duo Security, where he built and led the security research, development, and operations functions. After Duo’s acquisition by Cisco for $2.35 billion in 2018, Mike led the transformation of Cisco’s cloud security framework and later served as CISO for the company. Mike also spent several years at CERT/CC as a Senior Member of the Technical Staff and security researcher focused on applied R&D programs for the US Department of Defense and the Intelligence Community. When he’s not talking about security at GitHub, Mike can be found enjoying Ann Arbor, MI with his wife and eight kids.","url":"https://github.blog/author/mph4/"}]}</script>  <link rel='dns-prefetch' href='//ghcc.githubassets.com' /> <link rel='dns-prefetch' href='//js.monitor.azure.com' /> <link rel='dns-prefetch' href='//cdnjs.cloudflare.com' /> <link rel='dns-prefetch' href='//analytics.githubassets.com' /> <link rel='dns-prefetch' href='//stats.wp.com' /> <link rel='dns-prefetch' href='//v0.wordpress.com' /> <link rel="alternate" type="application/rss+xml" title="The GitHub Blog » Feed" href="https://github.blog/feed/" /> <link rel="alternate" type="application/rss+xml" title="The GitHub Blog » Comments Feed" href="https://github.blog/comments/feed/" /> <script> window._wpemojiSettings = {"baseUrl":"https:\/\/s.w.org\/images\/core\/emoji\/15.0.3\/72x72\/","ext":".png","svgUrl":"https:\/\/s.w.org\/images\/core\/emoji\/15.0.3\/svg\/","svgExt":".svg","source":{"concatemoji":"https:\/\/github.blog\/wp-includes\/js\/wp-emoji-release.min.js?ver=6.6.2"}}; /*!

As part of <a href="https://githubuniverse.com/">GitHub Universe</a>, I shared some numbers that provided a window into the work our engineering and security teams drive each day on behalf of our community, customers, and Hubbers. As someone who loves data, it’s not just fun to see how we operate GitHub at scale, but it’s also rewarding to see how this work contributes to our vision to be the home for all developers–which includes our own engineering and security teams.</p> <p>Over the course of the past year<sup id="fnref-69220-1"><a href="#fn-69220-1" class="jetpack-footnote" title="Read footnote.">1</a></sup>, GitHub staff made millions of commits across all of our internal repositories. That’s a ton of branches, pull requests, Issues, and more. We processed billions of API requests daily. And we ran tens of thousands of production deployments across the internal apps that power GitHub’s services. If you do the math, that’s hundreds of deploys <em>per day</em>.</p> <p>GitHub is big. But the reality is, no matter your size, your scale, or your stage, we’re all dealing with the same questions. Those questions boil down to how to optimize for <strong>productivity</strong>, <strong>collaboration</strong>, and, of course, <strong>security</strong>.</p> <p class="has-image"><img data-recalc-dims="1" decoding="async" src="https://github.blog/wp-content/uploads/2022/12/productivity-collaboration-security.png?w=1024&resize=1024%2C582" alt="" width="1024" height="582" class="aligncenter size-large wp-image-69222 width-fit" loading="lazy" srcset="https://github.blog/wp-content/uploads/2022/12/productivity-collaboration-security.png?w=1600 1600w, https://github.blog/wp-content/uploads/2022/12/productivity-collaboration-security.png?w=300 300w, https://github.blog/wp-content/uploads/2022/12/productivity-collaboration-security.png?w=768 768w, https://github.blog/wp-content/uploads/2022/12/productivity-collaboration-security.png?w=1024 1024w, https://github.blog/wp-content/uploads/2022/12/productivity-collaboration-security.png?w=1536 1536w" sizes="(max-width: 1000px) 100vw, 1000px" /></p> <p>It’s a running joke internally that you have to type “GitHub” three times to get to the monolith. So, let’s take a look at how we at GitHub (1) use GitHub (2) to build the GitHub (3) you rely on.</p> <h2 id="productivity">Productivity<a href="#productivity" class="heading-link pl-2 text-italic text-bold" aria-label="Productivity"></a></h2> <p>GitHub’s cloud-powered experiences, namely Codespaces and GitHub Copilot, have been two of the biggest game changers for us in the past few years.</p> <p class="has-image"><img data-recalc-dims="1" decoding="async" src="https://github.blog/wp-content/uploads/2022/12/productivity.png?w=1024&resize=1024%2C582" alt="" width="1024" height="582" class="aligncenter size-large wp-image-69223 width-fit" loading="lazy" srcset="https://github.blog/wp-content/uploads/2022/12/productivity.png?w=1600 1600w, https://github.blog/wp-content/uploads/2022/12/productivity.png?w=300 300w, https://github.blog/wp-content/uploads/2022/12/productivity.png?w=768 768w, https://github.blog/wp-content/uploads/2022/12/productivity.png?w=1024 1024w, https://github.blog/wp-content/uploads/2022/12/productivity.png?w=1536 1536w" sizes="(max-width: 1000px) 100vw, 1000px" /></p> <h3 id="codespaces">Codespaces<a href="#codespaces" class="heading-link pl-2 text-italic text-bold" aria-label="Codespaces"></a></h3> <p>It’s no secret that local development hasn’t evolved much in the past decade. The github/github repository, where much of what you experience on GitHub.com lives, is fairly large and took several minutes to clone even on a good network connection. Combine this with setting up dependencies and getting your environment the way you like it, spinning up a local environment used to take 45 minutes to go from checkout to a built local developer environment.</p> <p>But now, with Codespaces, a few clicks and less than 60 seconds later, you’re in a working development environment that’s running on faster hardware than the MacBook I use daily.</p> <p>Heating my home office in the chilly Midwest with my laptop doing a local build was nice, but it’s a thing of the past. <a href="https://github.blog/2021-08-11-githubs-engineering-team-moved-codespaces/">Moving to Codespaces last year</a> has truly impacted our day-to-day developer experience, and we’re not looking back.</p> <h3 id="github-copilot">GitHub Copilot<a href="#github-copilot" class="heading-link pl-2 text-italic text-bold" aria-label="GitHub Copilot"></a></h3> <p>We’ve been using GitHub Copilot for more than a year internally, and it still feels like magic to me every day. We recently <a href="https://github.blog/2022-09-07-research-quantifying-github-copilots-impact-on-developer-productivity-and-happiness/">published a study</a> that looked at GitHub Copilot performance across two groups of developers–one that used GitHub Copilot and one that didn’t. To no one’s surprise, the group that used GitHub Copilot was able to complete the same task 55% faster than the group that didn’t have GitHub Copilot.</p> <p>Getting the job done faster is great, but the data also provided incredible insight into developer satisfaction. Almost three-quarters of the developers surveyed said that GitHub Copilot helped them stay in the flow and spend more time focusing on the fun parts of their jobs. When was the last time you adopted an experience that made you love your job more? It’s an incredible example of putting developers first that has completely changed how we build here at GitHub.</p> <h2 id="collaboration">Collaboration<a href="#collaboration" class="heading-link pl-2 text-italic text-bold" aria-label="Collaboration"></a></h2> <p>At GitHub, we’re remote-first and we have highly distributed teams, so we prioritize discoverability and how we keep teams up-to-date across our work. That’s where tools like Issues and projects come into play. They allow us to plan, track, and collaborate in a centralized place that’s right next to the code we’re working on.</p> <p class="has-image"><img data-recalc-dims="1" decoding="async" src="https://github.blog/wp-content/uploads/2022/12/collaboration.png?w=1024&resize=1024%2C572" alt="" width="1024" height="572" class="aligncenter size-large wp-image-69224 width-fit" loading="lazy" srcset="https://github.blog/wp-content/uploads/2022/12/collaboration.png?w=1600 1600w, https://github.blog/wp-content/uploads/2022/12/collaboration.png?w=300 300w, https://github.blog/wp-content/uploads/2022/12/collaboration.png?w=768 768w, https://github.blog/wp-content/uploads/2022/12/collaboration.png?w=1024 1024w, https://github.blog/wp-content/uploads/2022/12/collaboration.png?w=1536 1536w" sizes="(max-width: 1000px) 100vw, 1000px" /></p> <p><a href="https://github.blog/2022-07-01-how-the-github-security-team-uses-projects-and-github-actions-for-planning-tracking-and-more/">Incorporating projects across our security team</a> has made it easier for us to not only track our work, but also to help people understand how their work fits into the company’s broader mission and supports our customers.</p> <p>Projects gives us a big picture view of our work, but what about the more tactical discovery of a file, function, or new feature another team is building? When you’re working on a massive 15-year-old codebase (looking at you, GitHub), sometimes you need to find code that was written well before you even joined the company, and that can feel like trying to find a needle in a haystack.</p> <p>So, we’ve adopted the <a href="https://github.blog/2022-11-15-a-better-way-to-search-navigate-and-understand-code-on-github/">new code search and code view</a>, which has helped our developers quickly find what they need without losing velocity. This improved discoverability, along with the enhanced organization offered by Issues and projects, has had huge implications for our teams in terms of how we’ve been able to collaborate across groups.</p> <h2 id="shifting-security-left">Shifting security left<a href="#shifting-security-left" class="heading-link pl-2 text-italic text-bold" aria-label="Shifting security left"></a></h2> <p class="has-image"><img data-recalc-dims="1" decoding="async" src="https://github.blog/wp-content/uploads/2022/12/security.png?w=1024&resize=1024%2C577" alt="" width="1024" height="577" class="aligncenter size-large wp-image-69225 width-fit" loading="lazy" srcset="https://github.blog/wp-content/uploads/2022/12/security.png?w=1600 1600w, https://github.blog/wp-content/uploads/2022/12/security.png?w=300 300w, https://github.blog/wp-content/uploads/2022/12/security.png?w=768 768w, https://github.blog/wp-content/uploads/2022/12/security.png?w=1024 1024w, https://github.blog/wp-content/uploads/2022/12/security.png?w=1536 1536w" sizes="(max-width: 1000px) 100vw, 1000px" /></p> <p>Like we saw when we looked at local development environments, the security industry still struggles with the same issues that have plagued us for more than a decade. Exposed credentials, as an example, are still the root cause for more than half of all data breaches today<sup id="fnref-69220-2"><a href="#fn-69220-2" class="jetpack-footnote" title="Read footnote.">2</a></sup>. Phishing is still the best, and cheapest, way for an adversary to get into organizations and wreak havoc. And we’re still pleading with organizations to implement multi-factor authentication to keep the most basic techniques from bad actors at bay.</p> <p>It’s time to build security into everything we do across the developer lifecycle.</p> <p>The software supply chain starts with the developer. Normalizing the use of strong authentication is one of the most important ways that we at GitHub, the home of open source, can help defend the entire ecosystem against supply chain attacks. We enforce multi-factor authentication with security keys for our internal developers, and we’re requiring that every developer who contributes software on GitHub.com <a href="https://github.blog/2022-12-14-raising-the-bar-for-software-security-next-steps-for-github-com-2fa/">enable 2FA</a> by the end of next year. The closer we can bring our security and engineering teams together, the better the outcomes and security experiences we can create together.</p> <p>Another way we do that is by <a href="https://github.blog/2022-04-19-sharing-security-expertise-through-codeql-packs-part-i/">scaling the knowledge of our security teams with tools like CodeQL</a> to create checks that are deployed for all our developers, protecting all our users. And because the CodeQL queries are open source, the vulnerability patterns shared by security teams at GitHub or by our customers end up as CodeQL queries that are then available for everyone. This acts like a global force multiplier for security knowledge in the developer and security communities.</p> <p>Security shouldn’t be gatekeeping your teams from shipping. It should be the process that enables them to ship quickly–remember our hundreds of production deployments per day?–and with confidence.</p> <h2 id="big-small-or-in-between">Big, small, or in-between<a href="#big-small-or-in-between" class="heading-link pl-2 text-italic text-bold" aria-label="Big, small, or in-between"></a></h2> <p>As you see, GitHub has the same priorities as any other development team out there.</p> <p>It doesn’t matter if you’re processing billions of API requests a day, like we are, or if you’re just starting on that next idea that will be launched into the world.</p> <p>These are just a few ways over the course of the last year that we’ve used GitHub to build our own platform securely and improve our own developer experiences, not only to <a href="https://resources.github.com/devops/tools/compare/">be more productive, collaborative, and secure</a>, but to be creative, to be happier, and to build the best work of our lives.</p> <p><div class="post-content-cta"><p><em>To learn more about how we use GitHub to build GitHub, and to see demos of the features highlighted here, take a look at this talk from GitHub Universe 2022.<em></em></em></p> <div style textalign="center"> <iframe loading="lazy" width="560" height="315" src="https://www.youtube.com/embed/R6iRccrJ_jg" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> </div> </div><br> </p> <p></p> <h4 id="notes">Notes<a href="#notes" class="heading-link pl-2 text-italic text-bold" aria-label="Notes"></a></h4> <div class="footnotes"> <hr> <ol> <li id="fn-69220-1"> Data collected January-October 2022 <a href="#fnref-69220-1" title="Return to main content.">↩</a> </li> <li id="fn-69220-2"> <a href="https://www.verizon.com/business/resources/reports/dbir/">Verizon DBIR</a> <a href="#fnref-69220-2" title="Return to main content.">↩</a> </li> </ol> </div> </body></html> <section class="my-6 my-md-8 mt-md-0"> <hr class="post-tags-separator border-0 mt-0 mb-2" /> <div class="d-flex flex-items-start"> <h2 class="text-mono f4-mktg py-1 mr-3">Tags:</h2> <ul class="d-flex flex-wrap px-0 my-0 list-style-none post-tags"> <li class="my-0"> <a href="https://github.blog/tag/how-github-builds-github/" class="d-block border py-2 px-3 f5 lh-condensed-ultra text-semibold Link--primary" rel="tag"> How GitHub builds GitHub </a> </li> </ul> </div> </section> <div class="mt-8 mb-8 mb-md-0"> <h2 class="h5-mktg"> Written by </h2> <div class="gradient-separator mt-3 mb-4"></div> <article class="author-bio mb-5 mb-md-4"> <div class="author-bio__content"> <div class="author-bio__avatar"> <picture> <source srcset="https://avatars.githubusercontent.com/u/16546317?v=4&s=200" width="120" height="120" media="(min-width: 768px)" /> <img class="d-block circle" src="https://avatars.githubusercontent.com/u/16546317?v=4&s=200" alt="Mike Hanley" width="80" height="80" loading="lazy" decoding="async" > </picture> </div> <header class="author-bio__header"> <h3 class="f3-mktg text-bold mb-1"> <a href="https://github.blog/author/mph4/" class="Link--primary color-fg-default">Mike Hanley</a> </h3> <p class="mb-0 f4 lh-condensed"> <a href="https://github.com/mph4" target="_blank">@mph4</a> </p> </header> <div class="author-bio__bio f4 lh-default"> <p>Mike Hanley is the Chief Security Officer and SVP of Engineering at GitHub.
