The log of the transported media and its classification marking would help the incident management team to most effectively analyze the business impact of the robbery. A log is a record of events or activities that occur on a system or a process, such as backup or transport. A classification marking is a label or a tag that indicates the level of sensitivity or confidentiality of the data or the media, such as public, internal, confidential, or secret. A log of the transported media and its classification marking would provide the incident management team with the information about what type of media and data was stolen, how sensitive or critical the data was, and what potential consequences or damages the data loss could cause to the organization or its customers. This information would help the incident management team to assess the severity and scope of the incident, and to prioritize and implement the appropriate response and recovery actions. A log of backup administrative actions, a log of the transported media and its detailed contents, and a log of backed up data and their respective data custodians are not as helpful as a log of the transported media and its classification marking, as they may not provide the relevant or sufficient information to analyze the business impact of the robbery, or they may be too cumbersome or impractical to maintain or access. References:
