Intrusion Detection and Prevention Systems
Security in network remains the dilemma all around the globe. Network personnel are most irritated by the Security breach in their organization either internally or by the culprit in the cloud.So first of all gaining enough knowledge on what does intrusion refers to in Computer Networks.
Introduction:
Intrusion refers to un-authorized entrance in the network without being noticed by network administrators.
Intrusion can cause stealing of information, alteration or even monitoring of information can cause series threat to the Network Systems.
The intrusion can also results in all kinds of attacks of the security of network.
Although, its true said that
"If you wanna know how not secure you are, just take a look around. Nothing's secure. Nothing's safe..."
but precautions does matters =)
Intrusion Prevention and Detection Mechanism:
Intrusion Prevention Mechanism can provide maximum safety to this threat and can save your network from some of the threats to be precise.
The purpose of IPS is to prevent the attacks on security, they can only be achieved if and only if the Intrusion is detected and the source is caught so in my whole blog i will be talking on both Intrusion Prevention as well as detection on the same and use IPS for both.
The IPS can performs:
Identifying security policy : It audits the security policies and if there is a loop hole in the policy it identifies it and notifies too.
Documenting the existing threat to an organization: If founds the treat then reports the threat for research and development and for profile development (it will be covered in the later posts soon).
Deterring individuals from violating security policies: IPS refrains the culprits not to intrude in the IPS monitored network since all the activities are being recorded .
