Spam can be defined as an unsolicited bulk message sent from one internet user to the other purposely used to mainly cause Denial of Service in a VoIP system, it is called Spam over Internet Telephony (SPIT). This research paper focusing on producing a test environment utilizing open source platforms that include Intrusion Detection System (IDS) with performance analysis. Kali Linux 2.0 will be used to illustrate the attack while Snort which is IDS software will work as a database that will monitor packet entering and leaving the system.
