    This month’s cheat sheet is about how you can secure your Spring Boot application. Spring Boot has dramatically simplified the development of Spring applications. Its autoconfiguration and starter dependencies reduce the amount of code and configuration you need to begin an app. If you were used to Spring and lots of XML in back in the day, Spring Boot is a breath of fresh air.

    In June 2018, the Snyk research team found many exploitable instances of the Zip Slip in various ecosystems that affected thousands of applications. This kind of wide reaching vulnerability requires a well thought out private disclosure process so that vulnerable libraries and projects are warned about their exposure before public disclosures are made. This post goes into the details of what we did throughout the process from discovery to disclosure, creating fix PRs and beyond.

    One of the main features in Java 10 in Local Type Inference, which allows us to substitute a type with the var reserved word in our source code. However, in order for this to become a feature that is useful to a developer rather than a feature developers will rue for many years to come, we need to learn how to use it and when to use it properly. This cheat sheet and blog is a reduced version of an blog post that Stuart Marks wrote on the OpenJDK site.

  • Guy Podjarny live hacks a Node.js application to exploit vulnerabilities in real world packages. In this edited down video from the JSKongress conference. Guy explains where some of the most common JS security pitfalls exist.

    The most common way for Snyk users to find out that they have an issue in their project is via our email alerts. It’s a core part of our service, but until recently, we didn’t have much in the way of configuration around what types of issues would trigger an email alert. As we scale our language support, enabling you monitor more projects in Snyk, we want you to feel better informed about the types of issues that matter to you, while making less noise about the issues that don’t.

  • DigitalOcean found and fixed a critical vulnerability within one day of disclosure using Snyk's automated remediation system.

  • Comic Relief integrated Snyk into their Concourse CI Serverless deployment pipeline which allows even the most junior of developers use open source securely by remediating any vulnerable libraries before they go to production.

  • I'm excited to announce our $7M Series A, and feel this is a great opportunity to say thanks!

  • We’ve just launched a new feature for our Pro and Enterprise Plan customers that adds an additional layer of hierarchy to make it possible to split your organisation in Snyk into teams, who can manage different projects. This has been a popular request from our customers and we’ve been building and refining it for months. We’re very excited to now be able to offer it.

    Ignoring security issues shouldn't be the default action, but it is sometimes necessary. Snyk only validates vulnerabilities that exist in dependent components, so it has a relatively low false-positive rate (which should reduce the need to ignore), but there are still reasons why you may wish to suppress an issue.

  • Guy Podjarny's avatar Guy Podjarny

    A vulnerability is a vulnerability, whether known or not. The key difference between the two is the likelihood of an attacker to be aware of this vulnerability, and thus try to exploit it.

  • You can't go to a security event nowadays and not hear at least a few speakers say the phrase "DevSecOps". The term has turned into a rallying cry for an approach that automates security throughout the development process. But in order for DevSecOps to succeed, it will first have to die.

  • Danny Grander's avatar Danny Grander

    The best solution for known vulnerabilities is to upgrade your software. But sometimes there's not a security update immediately available. The next best solution is to patch your software. In this post, we go through four ways to find security patches for open source software.

  • Open source maintainers give up their own time to create great pieces of free software, which we then use to create business value. In our State of Open Source Security Report, open source consumers and maintainers were asked about their security expertise, actions and sense of ownership—and the results were very mixed.

  • Locking or “pinning” dependencies is a widespread best practice in Ruby, Python, and other ecosystems. In Node.js locking was much less widespread, until recently, thanks to the improvements provided by package-lock.json and yarn.lock. This post discusses how each of these solutions works and why you may want to use them.

  • Stop building security tools that think about dev, and start building dev tools that handle security.

  • The Snyk API gives you access to all the issues associated with a given project. In this post, you'll learn how to use the API to fetch the organisations you have access to, the projects for a given organisation, and all the issues for a given project.

  • Snyk has always been committed to making it easy to use open-source code without compromising security. Today, we're taking another leap forward and launching support for .NET, Go and PHP!

  • Bower is no longer the dependency manager of choice for front-end projects. While the open source project is still maintained, its creators decided to deprecate it, and have advised how to migrate to other solutions. In this post, we explain why Bower used to be great, list six reasons why it isn't necessary anymore, and explain how to move on to newer and better technologies.

  • Last week, we released our first annual State of Open Source Security report. One of the discoveries the report mentions is that an analysis of around 433,000 sites found that 77% of them use at least one front-end JavaScript library with a known security vulnerability. In this post, we take a deep dive into that problem space.

  • Today we're excited to launch the 2017 State of Open Source Security Report! The full report is available as a free PDF, and the highlights are collected online.

  • Whether a vulnerability is currently exposed or not matters, but only in prioritization. Where its exploitable today or not, leaving it unaddressed is a unnecessarily risky decision.

    One of the biggest bottlenecks in security is 'triaging'—the process of validating if a security alert is actually impacting your organization, sizing up the estimated impact, and figuring out how to resolve it. In this article, we'll make the case that we should all be striving to skip triaging and focus on fixing vulnerabilities instead.

  • In this post we review and compare the Apache, BSD and MIT license to see what to use in your own project, and when.

  • Earlier this year we ran a test on the top 5,000 URL's on the web and found that 76.6% of them were running a JavaScript library with at least one known security vulnerability. It's a frighteningly large number. That's why we're proud to announce that Snyk now powers the vulnerable JavaScript libraries linter in Microsoft's Sonar—an open-source linting tool for developers.

    Python 3 and Python 2 have various functional differences. On their own, they’re not necessarily better or worse (though arguably Python 3 should be an improvement), but any change may introduce risk. This post highlights and explains a few differences between the versions that have security implications.

  • Geva Solomonovich's avatar Geva Solomonovich

    Where just a few months ago we launched Snyk for Serverless, we are now taking it to the next level by launching the Snyk Heroku Add-On. The add-on is currently in beta, which means it's free to try out! We're looking for people to take it for a test drive and provide us with some feedback.
