Episode notes
PSA Level 4 Means Strong Physical Protection
- PSA is a platform security architecture that evaluates both hardware and software implementations on chips and SoCs.
- PSA Level 4 is the top certification focused on protection against physical, local tampering attacks.
Match Security To Your Risk Profile
- Do perform a risk assessment to determine what level of security you actually need for your device and application.
- Apply security measures that mitigate unacceptable risks rather than aiming for impossible 100% security.
Security Is An Economic Equation
- Security is an economic equation driven by attacker incentive, access, and difficulty of attack.
- If a device holds valuable IP or is easily reachable, it becomes an attractive target regardless of size.
