Which aspect of testing can contribute to increased accountability in the organization?

Unique user identification in logs is essential for fostering accountability within an organization. When each user's actions are associated with their unique identifier, it becomes possible to trace activities back to the individual responsible. This transparency is crucial for auditing, compliance monitoring, and incident response.

If an incident occurs, having identifiable logs allows for an accurate assessment of who did what and when, facilitating swift investigation and remediation. This practice not only enhances security but also serves as a deterrent against malicious activities, as users are aware that their actions are being monitored and recorded.

In contrast, while frequent software updates, higher licensing costs, and strict access controls contribute to overall security, they do not inherently establish a direct link between actions and individuals like unique user identification does. Hence, they do not provide the same level of accountability within the organization.
