Networking Attacks in OMNeT++

Networking Attacks in OMNeT++ is any attempt to alter,destroy, disable,expose,gain or steal  unauthorized access to or make use of an asset.

Features of networking attack:

  • Performing actions to deplete network resources and bandwidth.
  • Performing actions that prevent legitimate authorized users from accessing network.

Types of networking attacks:

Major networking attacks are,

  • Internal threats.
  • External threats.
    • Structured threats.
    • Unstructured threats.

The sub network types are,

  • Access.
  • Reconnaissance.
  • Worms, viruses, and Trojan horses.
  • Denial of service.

 

 

Reasons for Network Attack:

  • Displeased employees might seek to damage the organizations data, reliability or financial standing
  • Possible motives for structured external threats includes racism, industrial espionage, criminal payoffs, greeds and terrorism.
  • Individuals seeking fame or some sort of recognition
  • There are some network attackers that simply enjoy the challenge of trying to compromise highly secured networks’ security systems etc.
