You want to 'attack' yourself, I do not see any problems. And I see lots of possible benefits.

This can be done internally using various traffic-generation and exploit-testing tools (plenty of open-source and commercial ones available). No need to build a 'botnet', literally - more of a distributed test-harness

And it must be *kept* internal; using non-routable space is key, along with ensuring that application-layer effects like recursive DNS requests don't end up leaking and causing problems for others.

We disagree.

I can think of several instances where it _must_ be external. For instance, as I said before, knowing which intermediate networks are incapable of handling the additional load is useful information.


But before any testing is done on production systems (during maintenance windows scheduled for this type of testing, naturally), it should all be done on airgapped labs, first, IMHO.

Without arguing that point (and there are lots of scenarios where that is not at all necessary, IMHO), it does not change the fact that external testing can be extremely useful after "air-gap" testing.


And prior to any testing of this sort, it makes sense to review the architecture(s), configuration(s), et. al. of the elements to be tested in order to ensure they incorporate the relevant BCPs, and then implement those which haven't yet been deployed, and *then* test.

You live in a very structured world. Most people live in reality-land where there are too many variables to control, and not only is it impossible guarantee that everything involved is strict to BCP, but the opposite is almost certainly true.

Remember, systems do not work in isolation, and when you touch other networks, weird things happen.


In general, I've found that folks tend to get excited about things like launching simulated attacks, setting up honeypots, and the like, because it's viewed as 'cool' and fun; the reality is that in most cases, analyzing and hardening the infrastructure and all participating nodes/elements/apps/services is a far wiser use of time and resources, even though it isn't nearly as entertaining.

Here we agree: Entertainment has (should have?) nothing to do with it.
