Intrusions and Their Lock in Data Communications Through Internet

Intrusions on entities in a network can be manifested by: identity theft, fraudulent routing, target flooding with protocol messages, and broadcasting an ICMP protocol messaging protocol. Intruders lead to blocking the service for legitimate users, and targets are flooded with unsolicited emails, Protection against such actions can be done with a number of security measures, such as: installing firewalls and installing intrusion detection systems. These safeguards can eliminate or even minimize the likelihood of materializing security threats and prevent attacks on the security features of a system.
