Which actions constitute a violation of information security?

The actions that constitute a violation of information security are those that compromise the integrity, confidentiality, or availability of sensitive information. Unauthorized access and mishandling of sensitive documents directly relate to these principles. Such actions may include accessing information without proper authorization, sharing sensitive information inappropriately, or failing to protect sensitive documents from exposure or misuse. These actions pose significant risks to organizational security and can lead to data breaches, loss of trust, and legal repercussions.

In contrast, reporting security risks is a responsible action aimed at enhancing security posture, regularly updating software systems protects against vulnerabilities, and participating in security drills ensures readiness and awareness among personnel. Each of these actions supports information security rather than violating it. Therefore, the correct choice highlights behaviors that fundamentally undermine the security framework in place to protect sensitive information.
