One site I've been following for awhile is https://notifycyber.com/

...but I'd love some more. What are your must-haves?

When it comes to all Linux distributions based on Debian (which is a good chunk of them), the Debian Security Advisory mailing list notifies you of all critical security updates and vulnerabilities. Even if you don't use Linux, it's still useful to see what was patched in relation to what CVE.

Welcome to the first operations security (OPSEC) community on Lemmy!

This is a space dedicated to discussing, sharing, and learning about operational security practices. Whether you are a business owner, a cybersecurity expert, or just a regular person, you can always benefit from a little extra OPSEC in your life.


Community Guidelines

As we belong to Lemmy.zip all of their guidelines apply on top of ours.

  1. Stay on topic:

    • Keep discussions related to OPSEC only
    • If your post is about this community instead of OPSEC prepend [META] to the title
  2. No illegal content:

  4. No Self-Promotion:

    • Refrain from excessive self-promotion or advertising
    • Occasional sharing of personal projects is allowed if it benefits the community

    • Do not provide advice without knowing the asker's threat model (except when providing general advice to the community)

What is OPSEC?

Operations security (OPSEC) is a process that identifies critical information to determine whether friendly actions can be observed by enemy intelligence, determines if information obtained by adversaries could be interpreted to be useful to them, and then executes selected measures that eliminate or reduce adversary exploitation of friendly critical information.

In simpler terms, it is the process of finding vulnerabilities that an adversary could exploit and patching them, thereby reducing your attack surface.

OPSEC is NOT a synonym for cybersecurity. It can encompass it; however, it also revolves around physical security.
