The field of the protection and the security of networks and services related to the growth and constantly evolving, it is to protect these devices and networks from accessing unwanted has been development the firearms and antivirus appeared the concept of discovery sneak intrusion detection systems Systems (ids) and Systems intrusion prevention intrusion prevention systems (ips), it operates systems to monitor the events that appear in devices and networks and analyzed to determine whether there is a breach or not. These events can be a breach of security policies set for the network or hardware related. In this paper, we define what information security and its components, and to clarify the types of attacks that get on the networks and malicious programs and methods of prevention, and the techniques and means of protection used. Finally we worked on the development of a simple program to try to prevent penetration, and by monitoring the envelopes or packages passers-by to the device Caller network software has been developed using the libraries and interfaces such as Java language Jpcap and PcapIf and pcapPacketHandler and others.
