This script focuses on three key settings that enhance protection against ransomware on your ESXi hosts:<\/h2>\n\n\n\n
- \n
- Encryption Mode<\/strong>: Checks whether TPM-based encryption is active.<\/li>\n\n\n\n
- Secure Boot Enforcement<\/strong>: Confirms Secure Boot is enabled.<\/li>\n\n\n\n
- Exec-Installed-Only Mode<\/strong> (Configured & Runtime): Ensures only binaries from installed VMware VIB packages can execute.<\/li>\n<\/ul>\n\n\n\n
Having these settings properly configured greatly reduces the risk of unauthorized code execution\u2014exactly what you want to fight ransomware!<\/p>\n\n\n\n
