Not all security-related incidents are preventable. This critical guide will help you put a response plan into place to catch incidents as early as possible and to minimize loss.
Computer security incident response has become an important component of information technology (IT) programs. Security-related threats have become not only more numerous and diverse but also more damaging and disruptive. New types of security-related incidents emerge frequently. Preventative activities based on the results of risk assessments can lower the number of incidents, but not all incidents can be prevented. An incident response capability is therefore necessary for rapidly detecting incidents, minimizing loss and destruction, mitigating the weaknesses that were exploited and restoring computing services. To that end, this publication provides guidelines for incident handling, particularly for analyzing incident-related data and determining the appropriate response to each incident. The guidelines can be followed independently of particular hardware platforms, operating systems, protocols or applications.
Because performing incident response effectively is a complex undertaking, establishing a successful incident response capability requires substantial planning and resources. Continually monitoring threats through intrusion detection and prevention systems (IDPSs) and other mechanisms is essential. Establishing clear procedures for assessing the current and potential business impact of incidents is critical, as is implementing effective methods of collecting, analyzing and reporting data. Building relationships and establishing suitable means of communication with other internal groups (e.g., human resources, legal) and with external groups (e.g., other incident response teams, law enforcement) are also vital.
This publication seeks to help both established and newly formed incident response teams. This document assists organizations in establishing computer security incident response capabilities and handling incidents efficiently and effectively.
