Short-Term vs Long-Term Containment
During the containment phase, it is important to distinguish between short-term containment and long-term containment:
Short-Term Containment:
- Purpose: The goal of short-term containment is to stop the attack immediately and limit its impact. This often involves quick, temporary measures, such as disconnecting affected systems, blocking malicious IP addresses, and isolating compromised user accounts.
- Actions: Actions taken during short-term containment are intended to provide immediate relief and prevent further damage until a more thorough containment approach is possible.
Long-Term Containment:
- Purpose: Long-term containment focuses on ensuring the attack is fully controlled without compromising operational capabilities. It involves more strategic actions, such as applying patches, configuring firewalls, or segmenting the network to prevent the threat from spreading further.
- Actions: Long-term containment measures should be designed to provide ongoing protection while the response team works on eradication and recovery efforts. These actions should be well-documented and involve consultation with other teams (e.g., IT, legal, communications).
Effective containment strategies require a balance between immediate actions to mitigate the attack’s impact and more strategic, long-term measures to prevent the incident from reoccurring.
