Talk By Mr. Satria Mandala (17 Feb 2011)

On the 17th February 2011 (Thursday) at Bistari 3 room (CICT), there was a talk who was organized by Prof. Dr. Abdul Hanan Bin Abdullah. The one who gave the talk was actually one of the Prof. Dr. Abdul Hanan Bin Abdullah Phd's student, that is Mr. Satria Mandala. He talked about 'Intrusion Detection Together with Critical Nodes Detection for Securing MANET'.


MANET is Mobile Ad-Hoc Network.
- Host movement frequent.
- Topology change frequent.
- No cellular infrastructure. Multi hop wireless links.
- Data must be routed via intermediate nodes


Security Issues:
- Classifications:
  --> External Attack VS Internal Attack
  --> Passive Attack VS Active Attack


Where is the attack start?
"The attack start from early stage of communication building, i.e. routing."


Example:
- Passive Attack --> jelly fish attack, worm hole attack
- Active Attack --> black hole attack


Routing Attack
- Modifications
- Worm hole attack (tunneling)
- Black hole attack
- DoS attack
- Invisible attack
- The Sybil attack
- Rushing attack
- Non-cooperation


Worm Hole Attack
- Colluding attackers uses "tunnels" between them to forward packets.
- Place the attackers in a very powerful position.
- The attackers take control of the route by claiming a shorter path.


Black Hole Attack
- Malicious node does falsification on the hop count (decrease hop count value) of RREP, as such the source of route discovery will justify that the malicious has shortest path towards the destination.


Security Solutions
- Monitoring using Intrusion Detection
- Encrypt Message Routing
