What is Containment?

Containment is a critical aspect of incident response, and involves the implementation of measures to limit the impact of a security incident and prevent it from spreading further within the organization. The goal of containment is to isolate affected systems or data to prevent further damage or loss, while allowing the organization to continue its normal operations.

​

The containment process typically involves several stages, including identifying the scope and extent of the incident, prioritizing affected systems or data, and implementing measures to isolate and contain the incident. These measures may include network segmentation, disabling affected systems or services, or isolating affected data.

​

Once containment measures have been implemented, affected systems or data are typically quarantined or secured to prevent unauthorized access or further damage. The organization may also implement additional security measures, such as enhanced monitoring or access controls, to prevent similar incidents from occurring in the future.

​

Finally, once the incident has been fully contained, the organization can begin the process of recovery and restoration, which involves restoring normal operations and data access, and addressing any necessary remediation efforts to prevent similar incidents from occurring in the future.

​

By implementing effective containment measures, organizations can limit the impact of security incidents and prevent them from causing significant damage or loss. Containment requires a deep understanding of technical systems, advanced problem-solving skills, and the ability to make rapid decisions in a high-pressure environment.
