Add random latency in incoming traffic

[Geniousdon]

I want to know how to add random latency in the Iptables through suricata ?
I need this to mitigate against timing covert channels. Any help will be appreciated.

you can’t define the exact latency but if you run Suricata in NFQUEUE mode you might add some minor latency in IPS mode since packets need to pass through the engine.
