What is least likely to be a responsibility of a first responder at a cybersecurity incident?

A first responder at a cybersecurity incident plays a crucial role in the initial stages of incident management. This includes responsibilities such as documenting the scene, securing evidence, and isolating affected systems to prevent further damage or data loss.

Documenting the scene involves noting down the specifics of the incident, including timestamps, actions taken, and observations that may be important for future investigation or analysis.

Securing the evidence is vital to ensure that all digital artifacts are preserved in a forensically sound manner. This includes safeguarding logs, hard drives, and any affected devices so that the information can be accurately used for analysis and investigation.

Isolating affected systems helps contain the incident, preventing the spread of any potential compromise and allowing for a clearer assessment of the situation without further contamination of the environment.

Offering courtroom testimony as an expert witness is typically not a direct responsibility of first responders at the scene of an incident. While they may have the knowledge and could be called upon later, this responsibility usually falls to cybersecurity professionals who have done deeper analysis, as well as legal experts who are involved in proceedings. Therefore, this task is least likely to be part of a first responder's immediate responsibilities during a cybersecurity incident.
