Windows TLS Status

Windows TLS Status

Description

This Plugin checks for the TLS Settings (SCHANNEL) of Windows machines. To go for sure you can check and set the TLS Settings with IISCrypto -> https://www.nartac.com/Products/IISCrypto

Setup:

Install the MKP
Deploy the Plugin via Bakery
Maybe adjust your requirements via the normal Service Rule

Assuming:

Windows Server 2022 has enabled TLS 1.3 by default.
Windows Server <2022 are not yet ready for TLS 1.3.
Maybe this changes in further windows updates.

Default Warning levels:

TLS 1.3 -> Ignored
TLS 1.2 -> Client + Serverside = Enabled
TLS 1.1 -> Client + Serverside = Should be Disabled
TLS 1.0 -> Client + Serverside = Should be Disabled

Sample Output:

protocol TLS1_3 as expected (S:0❘C:0)
protocol TLS1_2 as expected (S:1❘C:1)
protocol TLS1_1 (server) is not as expected 0 vs. 1WARN
protocol TLS1_1 (client) is not as expected 0 vs. 1WARN
protocol TLS1_0 (server) is not as expected 0 vs. 1WARN
protocol TLS1_0 (client) is not as expected 0 vs. 1WARN
