Which countermeasure is NOT applicable to protecting cloud operations from internal threats?

Redundant ISPs are primarily focused on ensuring network availability and reliability rather than directly addressing internal threats. While having multiple Internet Service Providers can provide a backup in case of failures or outages, it does not inherently foster protections against the risks posed by malicious or negligent insider actions. Internal threats may include data breaches, misuse of access, or unintentional errors made by employees. Measures like data masking, obfuscation, active electronic surveillance, and physical surveillance are directly related to mitigating these risks. They enhance security by monitoring, restricting access to sensitive information, and providing layers of defense against insiders who might exploit their authorized access for malicious purposes. These approaches specifically target the human element of security, which is crucial for protecting cloud operations from internal threats.
