The benefits of an intrusion detection system
One aspect of computer security will work to keep people from receiving unauthorized access: selecting good security passwords, using software to safeguard against well-known intrusions and so on. However whenever you reach a far more advanced level than this, intrusion detection systems or IDS will become an essential way to detect and mitigate attacks. The IDS monitor the performance of the computer or the account and then give some kind of alert when suspicious activity is detected.
For instance, Gmail carries basic IDS. This enables users to verify whether anyone has signed in to their account from a different location. In case you look at the list and only see your home IP address and phone number, everything is likely to be okay. In the event that some arbitrary IP address from Tokyo, Mumbai or Berlin is on the list, someone has certainly compromised your email account.
The IDS could be even more advanced than this. Whilst Gmail requires users to monitor things manually, there are automated systems to flag questionable activity and give warnings. For example, a computer system in a faraway country being able to view your Gmail using POP3 and will then start to download all the contents from your archive.
Obviously, the same applies to a situation in which some arbitrary army private begins accessing and download numerous diplomatic cables. From a computer security outlook, there must be some form of intrusion detection systems to spot this aberrant action. Attackers often become much more cutting-edge and their hits always improve. For that reason, people who would like to protect computer systems need to constantly increase their game by employing advanced security systems. Implementing IDS on personal computer systems and for cloud services such as Gmail will be a good way to know about breaches as early as possible and stop them from getting serious. It is certainly not comfortable to discover that you are struggling with an intruder, but it’s far better to have this knowledge than to carry on blindly whilst they continue their dubious actions.
Given that many individuals are constantly online nowadays and considering the fact that all operating systems come with security flaws which require time to repair, using an IDS will provide good protection for your computer. In fact, I am going to setup another system which is not connected to the web. In essence, it is obvious that computers connected to the internet will be even more vulnerable.
