Subject: [PATCH 3/3] Suricata: detect DNS events on port 853, too
Date: Thu, 07 Feb 2019 17:47:00 +0000 [thread overview]
Message-ID: <35331b2c-281e-f72f-fdd9-de8bfa592717@ipfire.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 960 bytes --]
As DNS over TLS popularity is increasing, port 853 becomes
more interesting for an attacker as a bypass method. Enabling
this port for DNS monitoring makes sense in order to avoid
unusual activity (non-DNS traffic) as well as "normal" DNS
attacks.
Partially fixes #11808
