Ensure 'Maximum SSL version enabled' is set to 'Enabled: TLS 1.3'

Opis

This setting sets the maximum required protocol version for the Transport Layer Security (TLS). The recommended state for this setting is: Enabled:TLS 1.3. Rationale: Setting TLS 1.3 as the maximum authorized protocol version mitigates the risk of using an insecure connection. 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\Mozilla\Firefox:SSLVersionMax (REG_SZ); compliant when it is 'tls1.3' (whitespace-insensitive). Remediation writes tls1.3 locally; in a domain set it through the ADMX so Group Policy does not revert it.

Kako se proverava

Metod provere: Windows registar

registry

$v = (Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox' -Name 'SSLVersionMax' -ErrorAction SilentlyContinue).'SSLVersionMax'; if ($null -eq $v) { 'unset' } elseif (($null -ne $v -and ("$v" -replace '\s','') -eq 'tls1.3')) { 'compliant' } else { "non-compliant: $v" }

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Komanda ljuske
