설명

This rule blocks executable files, such as .exe, .dll, or .scr, from launching. Rule ID and name: - 01443614-cd74-433a-b99e-2ecdc07bfc25 (Block executable files from running unless they meet a prevalence, age, or trusted list criterion) The recommended state for this setting is: 01443614-cd74-433a-b99e- 2ecdc07bfc25:2 (Audit) or higher. Rationale: Attack surface reduction helps prevent actions and apps that are typically used by exploit-seeking malware to infect machines. Launching untrusted or unknown executable files can be risky, as it might not be initially clear if the files are malicious. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Microsoft\Windows Defender\Windows Defender Exploit Guard\ASR\Rules:01443614-cd74-433a-b99e-2ecdc07bfc25 (REG_SZ); compliant when it is 2 or 1.
