What type of incidents does an incident handler primarily deal with?

An incident handler primarily deals with cybersecurity events and threats because their main role is to prepare for, detect, respond to, and recover from incidents that affect an organization's information systems and data. This focus includes various types of cyber incidents, such as malware infections, data breaches, denial of service attacks, and other threats that can compromise the confidentiality, integrity, or availability of digital information.

In the context of incident handling, the emphasis is predominantly on the digital landscape and threats that arise through networked systems. This encompasses understanding attack vectors, malware behavior, vulnerability management, and the protocols for responding to various cyber incidents. An incident handler's expertise is directed specifically at managing and mitigating cybersecurity risks, ensuring an organization's resilience against such digital threats.

Other options represent different areas of concern. Physical security breaches focus on threats to tangible assets and personnel, which, while important, fall outside the primary scope of an incident handler's expertise. Employee-related offenses can involve misconduct that may or may not have a cyber component, making it less aligned with the specific skills of an incident handler. Environmental disasters, while critical to an organization’s overall risk management strategy, pertain more to emergency management and disaster recovery rather than cybersecurity incidents that incident handlers primarily address.
