Intrusion detection systems

How are you?Hope so everyone would be safe and sound just like me as I am also safe Alhamdulillah.....

If I talk about intrusion detection systems then this is a significant component of network security which is specifically designed for identification and for alerting administrators about potential dangers. These systems are used for monitoring traffic of network, analyzation of patterns and detection of anomalies for preventing unauthorized access and denial of service attacks etc.If I talk about intrusion detection system solutions then these are used to enable organizations for responding to security breaches in a prompt way, minimization of damage and giving surety of business continuity.

Intrusion detection system solutions can be classified in diverse range of types in which each have unique and different characteristics like if I talk about network based intrusion detection system then these are helpful in monitoring traffic at a particular network and for analyzing packets and for identifying dangers.Similarly,there is another type which is host based intrusion detection system so its primary focus is at individuals hosting activities and in monitorization of calls and files etc.

If I talk about protocol based intrusion detection system then these are useful for examining particular protocols like HTTP or FTP etc.Last but not least distributed intrusion detection system is helpful where we need to combine different sensors for coordinated detection of any dangers across whole network.

Intrusion detection system comprises of various components in which first of all the most important component is sensor and as name is indicating that this is useful for collecting data of network which then forward to analysis engine.After that if I talk about analysis engine then it is used for examining data by making a comparison in between threat signatures and other patterns.

One more component to know is alert system which is used for notifying administrators of dangers that are detected and has been identified.Database is also a sort of component used for storage of threat signatures,other patterns and configuration of system.

Intrusion detection system is used for detecting by different techniques,ways and methods.From these methods there is one method which is signature based detection so it identifies threat pattern according to known matches.Secondly one method is anomaly based detection which is useful for identification of presence of any activity which is suspicious or unusual.When they have to detect or monitor system calls then they use behavioral detection method.

There are multiple benefits can be obtained when you implement intrusion detection systems like you can enhance security posture by real time detection of threats.If there are security beaches then you will receive a quick response after it's implementation as well as regularity needs may also meet in this way.You may see a clear reduction in false positives by more advancements in filtering and analysing which is another benefit.

Intrusion detection system are really effective but regarding challanges definitely I can say these are present so by its implementation more and more dangers will emerge time to time.More fine tuning need will increase will make false positive rates higher.Through it's implementation there will be more traffic network which would be difficult to handle then.Last but not least,it will increase integrity with other tools that are security related so coordination will seems to be seamless.

That's all about important points to discuss regarding intrusion detection system.Hope everyone understood it!
