Topic

Finding the Bad Apple in Your Regular Expressions

Description

Every modern programming language supports regular expressions. They are powerful tools to interact with data. They are also prone to a variety of mistakes, with consequences ranging from decreased readability, over logical errors, to performance degradation or even denial of service.

During this webinar, we will use descriptive examples to demonstrate:
- Some common mistakes while writing regular expressions
- How Sonar can detect problematic expressions
- Limitations of static analysis in this context
- Techniques to improve regular expression performance and defend against malicious inputs.

Message preview	Hi there, You are invited to the first SonarSource Virtual Event. When: March 4th, 2020 - 10am CST Topic: Empowering Developwer to own Code Security \| Learn how early feedback gives you control of your Code Security Security can be a daunting topic full of buzzwords and lots of opinions. At SonarSource, our approach is different. Join us, March 4th at 10am CST, for a live 30 minute presentation on SonarSource’s approach to Code Security and how as a developer, you can own the security of your code. During this session, G. Ann Campbell will share a brief overview of the Security Market, our SAST value proposition, and demo the developer security experience in SonarQube. You'll see how SonarQube: - Helps you understand the problem and the fix - Empowers Developers by shifting security analysis left - Can help every developer and development team write more secure code Register in advance for this webinar: https://sonarsource.zoom.us/webinar/register/WN_PsNaD8keSTWCtt-gFsBrnQ After registering, you will receive a confirmation email containing information about joining the webinar. ---------- Webinar Speakers Johann Beleites (Software Engineer @Sonar) Johann is a Java/Kotlin software engineer at Sonar, part of the team developing static code analyzers for Java and Kotlin, as well as Scala, Ruby, Go, and Apex.
