May I know what's the ESM version you're running ?
Also let us know if you're running standalone device or combo box ?
Kindly note that ESM uses TLS 1.2 from version 11.4.2 and we recommend you to upgrade the ESM version to our latest version 11.5.6 and check if your vulnerability scanner still reports the vulnerability.
I am on 11.5.5, and standalone, our vulnerability scanner showed it still vulnerable which we thought was odd. because we have 2 other environments on 2 other environments and only 1 showed vulnerable.
Further looking at the report. Looks like its rsyslog, thats the issue. With our product. Is there steps we can use to disable Rsyslog TLS 1.0/1.1. i know siem uses MLOS so i wanted to ask you if there were specific steps before i try something that could possibly be not supported.
|TLS Version 1.0 Protocol Detection||tcp||6514||The remote service accepts connections encrypted using TLS 1.0. TLS 1.0 has a|
number of cryptographic design flaws. Modern implementations of TLS 1.0
mitigate these problems, but newer versions of TLS like 1.2 and 1.3 are
designed against these flaws and should be used whenever possible.
As of March 31, 2020, Endpoints that arenâ€™t enabled for TLS 1.2
and higher will no longer function properly with major web browsers and major vendors.
PCI DSS v3.2 requires that TLS 1.0 be disabled entirely by June 30,
2018, except for POS POI terminals (and the SSL/TLS termination
points to which they connect) that can be verified as not being
susceptible to any known exploits.
|TLS Version 1.1 Protocol Deprecated||tcp||6514||The remote service accepts connections encrypted using TLS 1.1. TLS 1.1 lacks support for current and recommended|
cipher suites. Ciphers that support encryption before MAC computation, and authenticated encryption modes such as GCM
cannot be used with TLS 1.1
As of March 31, 2020, Endpoints that are not enabled for TLS 1.2 and higher will no longer function properly with major

whats odd is when i run openssl ciphers -v i only see SSLv3 and TLSv1.2
When we check the SSLCipherSuite.conf we have.
SSLOpenSSLConfCmd Curves secp384r1:secp521r1
SSL Protocol TLSv1.2:TLSv1.3
And rebooted but didnt matter.
