Conducting a lessons learned meeting is critical after resolving a cybersecurity incident as it helps in the analysis of what occurred, how it was handled, and what could be improved upon for future incident responses. Forensic analysis is more concerned with understanding how the breach occurred and does not focus on improving future responses. Drafting an SLA is generally a preparatory activity, not post-incident. Upgrading software might be a result of lessons learned but is not the definitive activity that encompasses evaluation for future prevention.
