What kind of actions should be taken following a security incident?

Following a security incident, it is crucial to document the incident thoroughly and take corrective actions. This approach ensures that the details of the incident are captured accurately, providing valuable information for identifying the root causes and improving security measures moving forward. Effective documentation assists in tracking patterns, understanding vulnerabilities, and reinforcing security protocols to prevent future occurrences.

Taking corrective actions is equally important, as it directly addresses the weaknesses that led to the incident and mitigates potential risks. This proactive stance helps an organization to bolster its defenses and prepare for similar incidents in the future.

The other choices do not align with best practices in incident response. Simply doing nothing would leave vulnerabilities unaddressed and could allow the situation to worsen. Reporting solely to an immediate supervisor or only involving law enforcement if deemed necessary can lead to a lack of comprehensive oversight, which might hinder the organization's ability to respond effectively and prevent future incidents.
