I am not sure sdwdate-gui would be a strong enough notification if networking was actually blocked if sdwdate did not succeed yet.

After running a bunch of tcp ping tests, the conclusion is this attack
is not really effective against TCP like ICMP. The latency is much lower
for TCP pings and though it slightly decreases with cpu stress it is not
consistent. Reloading pages in TBB with cpu stress
on/off does not impact latency readings while doing so with tc
attached has massive latency foot prints - implying it will ironically make such attacks much easier in addition to degrading performance.

Cyrus recommends adding delays per packet to disrupt inter-packet patterns that remain. The command can be fine tuned as such:

The good news is I think I've figured out the equivalent tc-netem command looking the slot parameter in the manual:

Any attempted access of /boot would be logged the same way anyway although it might be good to use that to stop it from showing up in aa-logprof.
Would an audit denyrule for /boot be useful for the sake of audit?
/boot isn't allowed in init-systemd anyway so we don't need to add it to dangerous-files. Apparmor denies access to files that aren't explicitly allowed. The only reason we need to blacklist /lib/modules and not /boot is because we give access to all libraries.
Still need to add /boot to https://github.com/Whonix/apparmor-profile-everything/blob/master/etc/apparmor.d/abstractions/dangerous-files? Currently cannot find it there.

Implemented for some time now.
Reported build failures:
When an implementation is decided, let's decide if we can include this in security-misc for use on Linux hosts and Kicksecure. We would need some way in detecting the active NIC since on wireless systems wlan0 is the interface of choice and not eth0
tc-netem is a utility that is part of the iproute2 package in Debian. It leverages functionality already built into Linux and userspace utilities to simulate networks including packet delays and loss.
