A Talk by Mr. Satria Mandala in Seminar In Info. Sec. Class (MCS 2070)

Assalamualaikum...This is my second assignment and i'm about to write a brief summary about a talk but this time by another PhD student under Prof. Dr. Abdul Hanan. This talk was held this morning (17th February 2011). This brief was presented by Mr Satria Mandala. He is from Indonesia. He had talked about the intrusion detection together with critical nodes detection for securing MANET. MANET is the short form for Mobile Ad Hoc Networks. He then briefing about Route Requests in AODV (Ad Hoc in Demand Vector), Reverse Path Setup in AODV, Forward Path Setup in AODV and Security Issues.

There are two classification of intrusion detecting system. One of them is External Attack Vs Internal Attack and the other one is Passive Attack Vs Active Attack. He stated that the external attack is more easy to be detected while the internal attack is legitimate mode and very dangerous kind of attack. While the passive attack is more dangerous and the attack is planned very well by the attacker. Somehow, there are many types of active attack. This includes black hole, selfish and fabric. He then told us where is the attack start. The attack is actually start from an early stage of communication building. For example, routing attacks, modification, wormhole attack (tunneling), blackhole, denial of service (DoS) attack, invisible node attack, the sybil attack, rushing attack and non-cooperation. For wormhole attack, the colluding attackers uses "tunnels" between them to forward packets. This will place the attacker in a very powerful position. The attackers take control of the route by claiming a shorter path. At last but least, Mr Satria then concluded the session with some security solutions with monitoring using intrusion detection and encrypt message routing. The talk is then dismissed.
