An organization, PARADIGM PlayStation, moved its infrastructure to a cloud as a security practice.

The decision to take the website and database server offline falls under the Containment phase of the incident response lifecycle. Here’s how the process typically unfolds:

Detection: The incident response team detects a potential security breach, such as an SQL injection attack, through network access logs using SIEM.

Analysis: The team analyzes the incident to confirm the breach and understand its scope and impact.

Containment: Once confirmed, the team moves to contain the incident to prevent further damage. This includes making the affected website and database server offline to stop the attack from spreading or causing more harm1.

Eradication and Recovery: After containment, the team works on eradicating the threat and recovering the systems to normal operation.

Post-Incident Activity: Finally, the team conducts a post-mortem analysis to learn from the incident and improve future response efforts.

References:The containment phase is critical in incident response as it aims to limit the damage of the security incident and isolate affected systems to prevent the spread of the attack12. Taking systems offline is a common containment strategy to ensure that attackers can no longer access the compromised systems1.
