Editor's Notes
- Security is only affordable for: Military/Gov Financial Post-Breach Orgs Economics of security are heavily tilted towards the attacker. As long as this remains, we continue to lose and lose ground.
- This is why most new tech fails. We’ve had electric cars forever, they are just too expensive to operate, maintain, and charge. We can go to space, but not affordably, yet.
- TIME CHECK – 15 MINUTES
- TIME CHECK – 20 MINUTES
- If you get an alert from a honeypot, it’s worth investigating. If someone hits your sign, the honeypot, they might hit your bridge, the sensitive system.
- A great NSM strategy is like a great cheeseburger.
- TIME CHECK – 30 MINUTES
- Kippo, Tom’s Honeypot, Thinkst
- Canary docs, canary DB tables, hash changes
- Honey Accounts, Honey SIDs, social media profiles
- TIME CHECK – 45 MIN
