The president of Leonidas's company is concerned about a significant increase in cryptographic malware that is impacting other companies in their industry. She has asked Kimon to ensure that the company's data will be recoverable if malware strikes and encrypts their production systems. What process does Leonidas need to undertake to be able to tell her that the company is covered?
Answer Options
Encrypt all sensitive data.
Hash all of the organization's data to detect cryptographic malware.
Perform backup verification.
Use anti-encryption technology to prevent the malware from encrypting drives.
Correct Answer: C
Explanation
Validating that the organization has secure and usable backups is Kimon's best answer. In case a system is affected by cryptographic malware, it's important to have reliable backups that are not encrypted by the malware. This requires keeping your backup systems separate from your main systems and potentially implementing version control so that your unencrypted backups are not overwritten by encrypted ones that become inaccessible. Encrypting sensitive data won't stop attackers from re-encrypting it, making it inaccessible. Hashing to detect the attack won't stop it or make it possible to recover, and anti-encryption technology does not exist.
