Suricata-IDS in IPS mode and "sysctl.conf" file

Help
1

Hello,
I’m running Suricata-IDS in IPS mode and recently, added below rules to “sysctl.conf” file:

$ cat /etc/sysctl.conf 
# sysctl settings are defined through files in
# /usr/lib/sysctl.d/, /run/sysctl.d/, and /etc/sysctl.d/.
#
# Vendors settings live in /usr/lib/sysctl.d/.
# To override a whole file, create a new file with the same in
# /etc/sysctl.d/ and put new settings there. To override
# only specific settings, add a file with a lexically later
# name in /etc/sysctl.d/ and put new settings there.
#
# For more information, see sysctl.conf(5) and sysctl.d(5).

Can it cause any conflict?

Thank you.

You should be fine. Of course, test and see how it goes.
