MANET By Mr. Satria Mandala (Phd Student)

This talk was organize on 17 February 2011. This talk was given by Prof. Dr Hanan Phd student at Bestari 3 room. The talk is about IDS with Critical Nodes Detection For securing MANET

A mobile ad hoc network (MANET), is a self-configuring infra structureless network of mobile devices connected by wireless links. ad hoc is Latin and means "for this purpose".

Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves or may be connected to the larger Internet. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a Link Layer ad hoc network.

There are security issues in MANET which can be classified as external attack VS Internal attack and also Passive attack VS Active attack.

Based on what Mr Satria talk the attack start from the early stage of communication building. The example of attack that he give are   Jelly fish attack, worm hole attack(passive attack), black hole attack (active attack)and also routing attack.

The solutions for this issue are to encrypt massage routing and monitoring it using IDS

VPN By Mr. Khalid (Phd Student)

This talk was organize on Thursday (10 February 2011) and was given by Mr Khalid who was a vice president of research and development in his company in Pakistan. The talk is about VPN.

A virtual private network (VPN) is a secure way of connecting to a private Local Area Network at a remote location, using the Internet or any insecure public network to transport the network data packets privately, using encryption. The VPN uses authentication to deny access to unauthorized users, and encryption to prevent unauthorized users from reading the private network packets. The VPN can be used to send any kind of network traffic securely, including voice, video or data.

VPNs are frequently used by remote workers or companies with remote offices to share private data and network resources. VPNs may also allow users to bypass regional internet restrictions such as firewalls, and web filtering, by "tunneling" the network connection to a different region.

Technically, the VPN protocol encapsulates network data transfers using a secure cryptographic method between two or more networked devices which are not on the same private network, to keep the data private as it passes through the connecting nodes of a local or wide area network.
