Analysts expect future attacks on industrial control system (ICS) networks to evolve from attacks that have immediate, direct impact to those with multiple stages and attack vectors that are more stealthy. Attackers aim to take the knowledge they ve already collected from past attacks to launch more ambitious, multi-stage attacks that could potentially be even more dangerous. The first and most obvious step is to improve visibility within industrial environments to identify potential malicious activity, report author Joe Slowik told Threatpost.
