Açıklama

This rule provides an extra layer of protection against ransomware. It uses both client and cloud heuristics to determine whether a file resembles ransomware. This rule doesn't block files that have one or more of the following characteristics: - The file has already been found to be unharmful in the Microsoft cloud. - The file is a valid signed file. Rationale: This ASR rule can help an organization enhance its protection against ransomware by using both cloud and local heuristics. 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:c1db55ab-c21a-4637-bb3f-a12568109d35 (REG_SZ); compliant when it is 2 or 1.
