Recent and anticipated changes in technology arising from the convergence of communications and computing are truly breathtaking, and have already had a significant impact on many aspects of life. Banking, stock exchanges, air traffic control, telephones, electric power, health care, welfare and education are largely dependent of information technology and telecommunications for their operation. We are moving towards the point where it is possible to assert that everything depends on software.
The increased capacities of information systems today come at the cost of increased vulnerability. Information technology has begun to produce criminal opportunities of a variety that the brightest criminals of yore couldn't even begin to dream about.
Intrusion-detection systems collect information from a variety of vantage points within computer systems and networks and analyze this information for symptoms of security breaches. Intrusion-detection and vulnerability-assessment technologies allow organizations to protect themselves from losses associated with network security problems. Intrusion-detection is the logical complement to network firewalls, extending the security management capabilities of system administrators to include security audit, monitoring, attack recognition, and response.

Cyber Crime

Cyber crime or e-crime or high-tech crime generally refers to criminal activity where network is the target or place of crime. The term cyber crime is used to describe criminal activity in which the computer or network is the necessary part of the crime.
