ICS malware has become more aggressive and sophisticated. Many industrial devices were built before anyone imagined cyberattacks such as Triton. ICS’s are now exposed to connected environments they were not designed for.
Standard McAfee security recommendations (vulnerability patching, complex passwords, identification control, security tools, etc.) remain the same as for regular networks, yet industrial systems also require specific procedures due to their importance. Industrial networks must be segregated from general business networks, and every machine connected to the industrial process should be carefully monitored by using strict access control and application whitelisting.
Further security recommendations:
Attackers learn what works from past attacks and from each other. Rapid developments in ICS threats make it crucial to stay protected. Manufacturers, plant operators, governments, and the cybersecurity industry must work together to avoid critical cyberattacks. More…
