Intrusion in lay terms is unwanted or unauthorized interference and as it is unwanted or unauthorized, it is normally and mostly with bad intentions. The intention of the intrusion is to collect information related to the organization such as the structure of the internal networks or software systems like operating systems, tools / utilities, or software applications used by the organization and then initiate connections to the internal network and carry out attacks. Intrusions are normally carried out by people outside the organization. Sometimes, intrusions can be caused by internal authorized persons carrying out these attacks by misusing their authorization or by internal authorized persons who go beyond their area of authorization and such attacks also need to be protected against.
