Which of the following measures helps security professionals defend against anti-forensics techniques?

Saving data in secure locations is integral to defending against anti-forensics techniques because it ensures that data is less vulnerable to tampering or unauthorized access. Anti-forensics aims to obstruct forensic investigation efforts by altering, deleting, or otherwise manipulating data to impede recovery and analysis. By securely storing data in designated, protected locations—like secure servers with access controls—security professionals can minimize the risk of that data being influenced by malicious actors or anti-forensic measures.

Secure storage practices often include measures such as access restrictions, encryption, and regular back-ups, which can deter or complicate attempts to manipulate or destroy data. This proactive measure not only ensures the integrity of the data but also facilitates forensic analysis if needed, as forensic investigators are more likely to retrieve untouched data stored in controlled environments. The other choices, while important aspects of security, do not specifically target the defense against anti-forensics with the same directness as secure storage practices do.
