Even if an organization’s operational landscape and threat vectors appear to remain unchanged, it is a best practice to frequently review and update the incident response plan. Threats constantly evolve, and what may seem like an unchanged threat landscape could still have subtle new risks that necessitate plan adjustments. Additionally, an incident response plan may have unrecognized flaws that only become apparent over time or through periodic testing. Therefore, it's a misconception to deem that revisions have limited utility without continuous, proactive evaluation.
