IEC 62443 CR 7.1: Denial of service protection

Components must be able to keep their essential functions running in a degraded mode when a denial of service event occurs (SL 1). RE 1, managing the communication load the component generates (SL 2): limit the impact of DoS by information or message flooding. The component has no counterpart to SR 7.1 RE 2, which the IIC list notes is a system requirement.

What else in your programme already covers this

This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
