A strong incident response plan - guidance that dictates what to do in the event of a security incident - is vital to ensure organizations can recover from an attack or other cybersecurity event and minimize potential disruption to company operations.
An incident response plan is a set of instructions to detect, respond to and limit the effects of an information security event.
Sometimes called an incident management plan or emergency management plan, an incident response plan provides clear guidelines for responding to several potential scenarios, including data breaches, DoS or DDoS attacks, firewall breaches, malware outbreaks, insider threats, data loss and other security breaches.
A formal plan ensures an organization uses its risk assessment and response activities to spot early signs of an incident or attack.
A well-organized incident response team with a detailed plan can mitigate the potential effects of unplanned events.
An incident response plan can speed up forensic analysis, minimizing the duration of a security event and shortening recovery time.
Situations exist where the severity of an incident is beyond the capabilities of an incident response team.
In these scenarios, incident response teams relay the information they know to emergency management teams and first responder organizations to try and resolve the incident.
To remain compliant with certain regulations, such as PCI DSS, having an incident response plan is critical.
A well-designed incident response plan can be the crucial differentiator that enables an organization to quickly contain the damage from an incident and rapidly recover normal business operations.
While a single leader should bear primary responsibility for the incident response process, this person leads a team of experts who carry out the many tasks required to effectively handle a security incident.
An incident response plan typically requires the formation of a computer security incident response team, which is responsible for maintaining the incident response plan.
As organizations build out their incident response teams, they should develop a series of playbooks that address their most common incident types.
An incident response communication plan should address how these groups work together during an active incident and the types of information that should be shared with internal and external responders.
Testing the processes outlined in an incident response plan is important.
A more in-depth testing approach involves hands-on operational exercises that put functional processes and procedures in the incident response plan through their paces.
Incident response plans should require a formal lessons-learned session at the end of every major security incident.
These sessions should include all team members who played a role in the response and provide an opportunity to identify security control gaps that contributed to the incident, as well as places where the incident response plan should be adjusted.
