Forrester Report: Why to automate AppSec now.

29 Cyber Security Blogs You Should Be Reading

Staying up-to-date is important for lots of reasons, but when you’re a Cyber Security professional, knowing about the latest tech, breaches, vulnerabilities,etc. is pretty much essential to your career. If you miss out on an important piece of news, your organization could miss out on much more.


More than just knowing what’s going on, though, keeping current in cyber security news is an opportunity to absorb and uncover innovative ideas surrounding InfoSec and the way you do your job.

The InfoSec community is lucky, to be honest. With so many security blogs available on the interwebs, the only real question we have to ask ourselves is: Which ones should I be reading on a regular basis? Well, for that we’re here to help. We’ve compiled a list of the blogs and security news sites we read and consistently gain value from on every visit.


The following cyber security blogs are those we consider thought-leaders in each of their niches and offer a full range of topics within cyber security. We hope you’ll discover some new reading material, and if we missed one of your favorite cyber security blogs, tweet us and let us know @Checkmarx!
Note: These blogs are in no particular order!


Independent Cyber Security Bloggers:


Krebs on Security 


A Washington Post investigative reporter turned independent cyber security journalist and blogger, Brian Krebs regularly blows the covers off security breaches (Remember Target?) and the schemes of cybercriminals. His blog is an intriguing mix of posts on tips he’s received and security news we need to know.


He may not come from a cyber security background, per se, but he has something not many other bloggers do: friends in high (and geeky) places. “Much of my knowledge about computers and Internet security,” Krebs writes, “comes from having cultivated regular and direct access to some of the smartest and most clueful geeks on the planet.” An experienced journalist with connections to the world’s top security gurus? If it sounds like a blog you need to be reading, it’s because it is.

Run by Robert Graham and David Maynor, Errata Security is always a terrific read, with opinionated, smart posts on all things security, and a big focus on government surveillance.

He is also the creator of Whisper Systems, whcih was bought by Twitter. Moxie (a pseudonym by the way) blogs about cryptography, secure protocols, privacy and anonymity in a relatable but still intelligent way.


Troy Hunt


He’s a Microsoft MVP for Developer Security, so you can be sure it gets technical on Troy’s blog. He writes mostly about improving security within development and drills down on important security concepts.


Aside from his blog, Troy (@troyhunt) also runs Have I been pwned, which allows anyone to check if their email has been found in hundreds of stolen databases and another great community addition.

A household name in security and cryptography, Bruce’s blog is teeming with his take on the most relevant topics in the industry. If you’re not already one of the 250K+ readers and subscribers to his monthly newsletter, it’s time to get on board!
