Azure DevOps versioning

A common scenario when integrating security in development activities, such as SAST scans covered in my previous blog post, is to create a reusable template that can be referenced from pipelines.

If you are new to templates I suggest you take a look at this article from Microsoft before reading further.

Security templates in Azure DevOps

In this blog post we will explore how to create a basic reusable Azure DevOps template to automate code analysis, using a popular SAST tool from Veracode. You would ideally want all development teams to have a way to enable SAST scans with minimum configuration, so that they focus their efforts on remediation instead of configuring tooling in their pipelines. That is where Azure DevOps pipelines come in handy, as they cover the reusability part and thus making it a bit easier for developers.

Application L7 Denial-of-Service attacks

In February 2023 Sweden suffered a series of Distributed Denial-of-Service attacks (DDoS) and several Swedish websites were knocked down. A DoS is a type of attack that the attacker uses to make victim services unavailable, usually by sending large number of malicious requests. The number of incoming requests becomes so high that legitimate requests end up not being handled by the victim's services, thus the denial-of-service. DoS is also usually distributed in the sense that multiple bots (or zombies) and attacker-controlled machines take part in the attack to increase the probability of a successful attack. As reference, Cloudflare stated that it stopped a DDoS peaking 71 million requests per second in February 2023!

Github Advisory database

Dependabot is the way Github alerts you about security vulnerabilities in open source dependencies. The Github Advisory Database is where Dependabot draws it's knowledge from, meaning it is the database used by Dependabot to identify vulnerabilities in dependencies.
