tl;dr
Working on the pulling together updated information here on a new platform. Until then, here are a few things from the top of my head:
● Want to know if your information has been found in a known breach? Check out haveibeenpwned.com and sign up for alerts.
● Interested in open-source threat hunting and monitoring? Install Security Onion!
● Looking for a secure live environment for browsing anonymously? Perhaps Tails (The Amnesic Incognito Live System) might be what you are looking for.
● Need security baselines for your operating systems? Review Center for Information Systems (CIS) Security Benchmarks and apply relevant settings.
● New or seasoned Blue-teamer looking for a podcast? Subscribe to my colleagues at detections.org and show support.
Will have more resources here in the near future so please check back soon after I aggregate some content. Thanks!
