Secure PLC Coding

Secure PLC Coding Practices - Part 3 (Lab) (ICS053)


Description

Lab: 2 CPE


So much attention is paid to securing industrial control systems at various levels in the network, but what can controls engineers do to help secure the PLCs that are actually translating digital commands into physical actions?


In this 4-part series learn how the "Top 20 Secure PLC Coding Practices" provides PLC programmers with the first ever industry guidelines for adding basic security to the PLC programming itself. Practice the various guidelines in simulated ICS networks including power generation, power distribution, and building automation networks.


Part 3 of the 4-part series covers:

  • Practice 3: Leave operational logic in the PLC
    • Practice 20: Trap false negatives and false positives for critical alerts
    • Practice 8: Validate HMI input variables at the PLC level
    • Practice 6: Validate timers and counters
