Re: DoS test on specific TCP Port

[Benjamin Greenfield <bcg () struxural com>]

You can try using hping3 to send out all sorts of traffic in all kinds
of different frequencies and bursts.   However, the first thing you
should do is verify with your client that they consent to you trying a
DoS attack.  Depending on application / service / OS is connected to
that port there may be particular vulnerabilities and / or exploits
that result in DoS conditions as well.

As far as determining the effectiveness of the attack, you'd need to
log all the incoming responses and evaluate them I suppose.  I would
expect subtle differences would account for things like an IPS
blacklisting your IP versus the host actually going offline or slowing
due to load, and depending on the specifics it may not actually be
possible to determine what precisely occurred target-side happened.

Seriously, verify that the client wants you to test a DoS first though...

Prove to peers and potential employers without a doubt that you can actually do a proper penetration test. IACRB CPT 
and CEPT certs require a full practical examination in order to become certified.
