[Oisf-users] Two questions about using suricata as IPS in production environments

After sometime using suricata as IDS in our infrastructure, next step
is to move these suricata sensors as an IPS.
At this point I have some doubts. From the point of view of software
and hardware failure, I see two "problems":
a) If we made some mistake reconfiguring suricata, or appears some
error with rules or if appears some another type of problem at
software level, suricata stops. Then, due to this is a production
environment, all traffic that cross this sensor, it doesn't flow. If I
am not wrong, configuring a bridge at SO level, this problem
disappears. Is it correct??
b) The most important problem: a hardware failure (network interfaces
goes down). What to do in this case?? Due to this is an
electronic/electrical problem, what type of hardware do I need to
use?? Commercial products as for example, Sourcefire appliances solves
these type of problems.
There is a third path to avoid a hardware problem: use virtualization
(ESXi as a first option). But this is an important performance
All suricata IDS sensors are installed in FreeBSD hosts ... And this
is our first SO option. I don't want to use any Linux with systemd in
Many thanks for your help.
