DEPLOYMENT AND IMPLEMENTING OF AN IDSThe strategy for deploying IDS should consider various factors. These factors will determine the number of administrators required to install, configure, and monitors IDS, workstations management, the size of the storage required for retention of the data which is generated by the systems.IDS Control StrategiesIDS can be implemented by means of one of three basic control strategies-Centralized: all the IDS control functions are implemented and managed in a central location which is shown in Figure given below.
-Fully distributed: all control functions are applied at the physical location of each IDS component that is shown in Figure A given below.
-Partially distributed: combines two; while individual agents can analyze and respond to local threats, they report to hierarchical central facility to enable organization to detect widespread attacks that is shown in Figure B given below.
