All of the following methods can be used to attenuate the harm caused by escalation of privilege except:

Extensive access control and authentication directly limit unauthorized privilege changes, thus attenuating harm from escalation.

Frequent analysis of log data helps detect anomalous activity that could indicate or lead to privilege escalation, enabling timely response.

Cryptographic sanitization tools are designed to securely erase data from storage media by encrypting it and then discarding or destroying the encryption keys, rendering the data unrecoverable. This process is unrelated to preventing or detecting privilege escalation.

Automated analysis tools like SIEM/SEM solutions are crucial for real-time monitoring and alerting on security events, including potential privilege escalation attempts, thereby helping to mitigate harm.
