The best practice to prevent misuse of administrative privileges is to have administrators use a separate non-privileged account for routine tasks that do not require administrative rights. This reduces the risk of accidental changes or security breaches that could occur if the administrator's highly privileged account were compromised or misused during daily operations.
Reference = This control measure is aligned with the principle of least privilege and is commonly recommended in cybersecurity frameworks. While I cannot cite the Cybersecurity Audit Manual directly, similar guidelines are often included in cybersecurity literature and standards, including those from ISACA1. For specific references, please consult the ISACA Cybersecurity Audit resources.
