In a central log management system, which approach is best for ensuring data integrity and security?

In a central log management system, employing the principle of least privilege is pivotal for ensuring data integrity and security. This principle dictates that users and systems should have the minimum level of access necessary to perform their tasks. By limiting access rights, the risk of unauthorized modifications or deletions of log data significantly decreases.

When implementing least privilege, the system administrators can control who can view, modify, or delete logs, thereby reducing the potential for insider threats, accidental changes, or malicious activities. This approach ensures that only authorized personnel can access sensitive logs and that their actions are traceable, thus maintaining the integrity and security of the log data.

Other approaches like open access may expose sensitive information broadly, which could lead to data breaches. Standardization is primarily related to ensuring uniformity in log formats and storage but does not inherently protect data from unauthorized access. Classification helps in determining the sensitivity level of the logs but does not directly enforce access control measures. Therefore, adopting least privilege is the most effective strategy for safeguarding log data.
