For exchange operators, cybersecurity is paramount. What are the critical best practices and technologies you've adopted to protect customer assets and data, especially against sophisticated APTs and ransomware attacks?
Two-factor authentication and multi-sig wallets are non-negotiable. For APTs, I'd say constant threat hunting and penetration testing are key, not just annual audits.
Beyond technical controls, employee training is huge. Social engineering is often the easiest way in, no matter how strong your firewalls are.
We've focused heavily on anomaly detection and AI-powered threat intelligence. The sheer volume of new threats means manual oversight isn't enough anymore.
Endpoint detection and response (EDR) coupled with a robust SIEM solution are standard, but the real challenge is integrating them effectively to get a full picture.
Zero-trust architecture is the direction everyone should be heading. Never trust, always verify, even for internal networks.
Don't forget about physical security. All the digital defenses in the world won't matter if someone can just walk in and plug in a USB.
What about incident response plans? Having a well-rehearsed plan for every scenario, including ransomware, is crucial for minimizing damage and restoring trust.
Data encryption at rest and in transit is fundamental. But keeping up with decryption key management securely is a whole other beast.
