Intrusions into an information system are very easy to detect as long as the patterns that are formed whenever the data is being accessed can be collected. These access attempts will usually cause a flare-up of data when there have been too many unsuccessful attempts and in most cases the systems that are being accessed will notice one IP address trying to access the information system or intrude. Intrusions can also be caused by apps that are sending requests to the web server that is responsible for keeping the application alive with the latest information and in cases when there is an interruption of service or the server doesn’t have enough network connection, the apps that are trying to communicate with it will send too many requests that can have an impact on the server performance and its safety.
Intrusions are not always easy to notice as most of the attempts at gaining access into information systems are discrete and very silent. Most of the actions by the hacker are concealed and your security systems will not even raise an alarm when they are under attack by the hacker. Other intrusions also happen whenever there are users who try to create multiple accounts to access the same systems. By detecting the intrusions, the users of the information system get to secure their assets better and restrict access to the unwanted parties that try to gain forced access into the information system. These intrusions are not always detectable and sensitive security systems for the information can be useful to detect the intrusions.
Keeping a log of all the access attempts on an information system also makes it possible for system administrators to avoid the intrusions and get alerted the very moment an obvious intrusion is attempted. The detection strength of the system will be based on how well the system is able to learn and adapt its methods in detecting the intrusions and can determine how well the system stays secured. It is also the reason modern systems have firewalls that are programmable to block out given IP addresses in a range of incoming request from certain network sections. Once these addresses get blocked, the attempts at intruding into the system are all weakened and the system stays and maintains its state of security.
The strength of being able to detect intrusions comes with preventing attacks before they are carried out. Modern information systems come under a lot of attacks and with proper security measures in place; nothing can be able to get past the firewalls especially when the incoming traffic has been flagged as being suspicious. The detection of intrusions can be made possible through a thorough analysis of data access patterns. Not only does this ensure that all incoming traffic is verified and authenticated, but also prevents unwanted users from gaining access into the systems. The design and development of security systems also takes into consideration the intrusions that are possible on the information systems that are being protected and with this detection comes better security for the information.
