#Web3.0 Requires Data Integrity

schneier.com/blog/archives/202

Schneier on Security · Web 3.0 Requires Data Integrity - Schneier on SecurityIf you’ve ever taken a computer security class, you’ve probably learned about the three legs of computer security—confidentiality, integrity, and availability—known as the CIA triad. When we talk about a system being secure, that’s what we’re referring to. All are important, but to different degrees in different contexts. In a world populated by artificial intelligence (AI) systems and artificial intelligent agents, integrity will be paramount. What is data integrity? It’s ensuring that no one can modify data—that’s the security angle—but it’s much more than that. It encompasses accuracy, completeness, and quality of data—all over both time and space. It’s preventing accidental data loss; the “undo” button is a primitive integrity measure. It’s also making sure that data is accurate when it’s collected—that it comes from a trustworthy source, that nothing important is missing, and that it doesn’t change as it moves from format to format. The ability to restart your computer is another integrity measure...

In case you're not up-to-speed on what #FastFlux #DNS is, it's part of the arms race between attackers and defenders:

THREAT ACTOR: This is my C2 IP
BLUE TEAMER: Blocked at the firewall

TA: Ok, well then, here's my C2 domain. I've rented 50k botnet nodes to use as proxies to my real C2 infrastructure, and I'm going to keep changing the IP the domain points to basically forever. Good luck blocking that. [FAST FLUX]
BT: Blocked the domain's nameserver's IPs at the firewall

I constantly get asked what cert to get to land a cybersecurity job. Truth is: certs help, but they’re not everything. Learn to apply the knowledge. Homelab, document on GitHub/blog, and most importantly—network. I’ve been in this field nearly a decade. First cert? CISSP—last year. #Cybersecurity
