Large scale information systems are known to hold a lot of information which must be well defended at all times. The structure and architecture of these systems means that they are high risk systems that can lead to the loss of business and huge economic downfall whenever they are attacked. Defending large scale information system means that any party that is trying to make the wrong use of the system does not get a chance to access the information system in the first place and this means that they are kept off limits and safely away from the information that is residing on the information system.
The first means of defending the information system is by use of a login mechanism which ensures that all the parties that are trying to get into the system are verified for their security credentials before they can be allowed into the system. Using an authentication system, the information system will be able to control who gets allowed into the system and who does not get allowed entry. The authentication will also control how far into the system someone that has been granted access will be allowed access and administrators are the only ones that get complete access over the information system.
Another way to ensure that hackers and other criminal elements are not given the chance to gain access into a large scale information system is by use of a honeypot. The honeypot is designed to be a replication of the information system that is way easy for the hackers to access and simply placed in the way of the hackers in order to prevent them from accessing the real information but getting stuck in the honeypot. Honeypot systems are used for the convenience of the information system and any unauthorized parties will get redirected to the honeypot instead of the actual system which is quite simple and graceful for uninvited parties to stay outside the information system.
Firewalls and other applications have not been left behind with respect to the defense of large scale information systems. They are usually configured to act as a means of restricting the access to the information systems and often filter out the unwanted IP addresses that have been recorded by the honeypot as being malicious characters. They are quite effective at keeping out unwanted traffic and the information systems are much easier to run when they can keep out all the unwanted traffic from their information.
In conclusion, there are information systems which are very sensitive and can run into huge losses whenever there is unauthorized access into the system by parties whose sole intention is to take bad advantage of the system. By employing the measures that have been described in the sections above, your information system will be kept away from the reach of malicious hackers and other criminals that are intent on getting past the deterrent and measures that you have employed to keep them away from the information systems which keep your company or business running and providing services to customers.
