ISACA – The Information Systems Audit and Control Association – is a good resource for Incident Response Teams.
The ISACA Web Site offers a white paper: Incident Management and Response. This is a link to the base page with access to the white paper as well as a good set of additional resources for Incident Planning and Response.
The paper makes key points that help strengthen a response plan including:
Risk planning and response planning are linked. The risks and resulting impacts occur in the following areas:
A robust incident response program reduces the risk of response – the probability of the response itself contributing inadvertently to risk exposure. The paper stresses the characteristics of an effective program:
For each impact area, it is important to provide metrics or descriptions that differentiate the impact level. Low, medium, and high are not enough as impact measures. Without metrics different people assign different meanings to the terms low, medium, and high.
It’s worth stressing that the impact component of the risk assessment can and should be used during the Incident Impact Assessment. The Response Team measures adverse impact to determine the needed response.
With this information the response team makes informed decisions on what resources to apply and what actions to take. Refer to our Response Management Framework for added insight.
