Regarding “IDS and IPS(IDP) who more satisfied user's needs?”This question, two chooses a feeling for the human. Regarding IDS and IPS field discussion, also Gartner Corporation vice-president Richard Stiennon publication's named "Invasion Examination Has died in bed of old age from 2003, Invasion Defense Will be ever-fresh" the report starts in the security field to start not the small fluctuation. Argued after the such long time's repeated writing that as well as the onlooking recent product development and the market feedback, the calm field public figure and the customer already saw this is simply not one two chooses a question. Replied that this question and does reply “who IDS and the firewall more satisfied user's needs?”“IPS and firewall who more satisfied user's needs?”These questions are the same.
what “are the user's needs”?
Which product more satisfied user's needs analyzes, needs our truly seeing clearly user the security requirements is anything.
Very obviously, the user need is not the sole product, is also not the numerous product simple stacks. Now a quite popular view is “the information security safeguard system (system)”. Is also user's safety is must depend on numerous essential factors and so on technical products, service and management combines a complete system, solves the security threat which faces to protect own information property and the service.
In the above safety control frame, the different product, the service, the measure in the different place display function. For instance, PKI and biological distinction mechanisms in “distinction authentication” domain, invasion examination in “monitor, monitoring and early warning” domain, firewall and IPS in “access control” domain, data encryption and content filtration in “content security” domain, and so on. Discusses different safety work domain that even more to meet user's demand, was actually inferior how discusses to let each kind of safety work how effectively joint operation.
Certainly, some technologies will surmount many areas of technology, for instance VPN will have both the access control and the content safe two aspects. IPS is other example, its technology involves to the access control and examines two aspects.
IPS really can substitute the firewall and IDS? Had the steamed stuffed bun, does not need the steamed bun and the meatball? Inside the key needs to look how many IPS has covered?
The security function satisfies the security requirements, is not the word game
Provides IPS(IDP) the manufacturer to declare frequently its IPS can have both firewall's gateway defense capability and the invasion examination depth examination.
“Mr./Ms. IPS may examine each kind of aggressive behavior precisely. Mr./Ms. IPS deployment in…The depth inspects each turnover the data packet. When examines the malicious current capacity, this equipment will discard the corresponding connection, will enable it to enter the network.”
