Certified Secure - Ineffective Detection Systems

This presentation discusses the limitations of intrusion detection systems (IDS) in securing networks against hackers. It argues that IDS will not stop skilled hackers for several reasons. Signature-based IDS cannot detect unknown attacks since new vulnerabilities are found daily. Anomaly-based IDS require extensive manual labor to create accurate network profiles and cannot adapt to changing networks. Additionally, IDS only make guesses about network traffic and have no way to definitively determine if traffic is malicious. Using an IDS also introduces new risks, as the IDS itself has vulnerabilities that could allow an attacker to compromise the entire network if the IDS is breached. Instead of relying on IDS, the presentation recommends directly addressing existing security problems on networks
