Intrusion detection (ID) is a type of security management system for computers and networks. An ID system gathers and analyzes information from various areas within a computer or a network to identify possible security breaches, which include both intrusions (attacks from outside the organization) and misuse (attacks from within the organization). ID uses vulnerability assessment (sometimes referred to as scanning), which is a technology developed to assess the security of a computer system or network.
Intrusion detection functions include:
- Monitoring and analyzing both user and system activities
- Analyzing system configurations and vulnerabilities
- Assessing system and file integrity
- Ability to recognize patterns typical of attacks
- Analysis of abnormal activity patterns
- Tracking user policy violations
ID systems are being developed in response to the increasing number of attacks on major sites and networks, including those of the World Trade Centre in New York and the Pentagon. The safeguarding of security is becoming increasingly difficult, because the possible technologies of attack are becoming ever more sophisticated; at the same time, less technical ability is required for the novice attacks, because proven past methods are easily accessed through the web.
The parking entry or parking management system is used to manage the parking facility effectively in a building or a campus or for generating revenue from a parking facility or providing high level security for parking in highly secure buildings or facilities.
It comprises of the combination of the following systems:
- Boom Barriers
- Boom Barriers
- Raising Bollards
- Road Blockers
- Parking Entry Station or Pay stations
- Automatic Number Plate or License Plate Recognition Systems
- Vehicle Scanning Systems
- X-Ray Detection, Metal Detectors, etc.
