Traditional network security has typically addressed the harms of external attacks, but insider threats are quickly becoming a major challenge to overcome and often neglected. Every network has malicious traffic which may be someone outside trying to gain information or a disgruntled employee on the inside looking to cause havoc. Whomever the culprit, you want to know and do something about it. To avoid the risk of insider threats, a complete Network Intrusion Detection System (NIDS) is required which tells you about the attack so that you can keep the unauthorized intrusion from impacting your business.
