Rigid plans and incident response tools can make it difficult for the team to deal with unexpected situations. Ideally, the incident response plans and tools should be regularly reviewed to consider its effectiveness against new types of security threats being faced by your industry.

The incident response plan and the tools to be used should clearly establish the communication channels to be used in case of a security incident. The different aspects pertaining to communication like whom the incident team should communicate with, which communication channels have to be used, and what information has to be communicated, needs to be clearly defined.
The nature of information to be communicated to different levels and hierarchy should also be defined in the incident response plan. Though this is an important aspect of incident response planning and use of incident response tools, it remains ignored in most incident response plans.

The type of stakeholders to be informed and involved can keep changing based on the nature of security incident.
