Any information system used at a company, business, or organization tends to be connected or networked to the outside world and users through a network or some other organized connection. A networked system will require keeping the resources on the inside of the network safe and secure from all kinds of harm directed at the applications. Hackers and other kinds of information system criminals are always working round the clock on new methods and ways of reaching into information systems to steal information or infect them, thus causing vulnerabilities that can be taken advantage of.
Good defenses for information systems are not only in the network structures but also in the design of the systems’ structure to prevent information from getting leaked from them. The system’s design also makes it possible to defend from external threats while still maintaining the system’s active performance. An information system that is securely protected from external threats will rarely develop performance issues as there is nothing that can be able to get into the system and eat away at the information that is on it.
A lot is invested into the defense of an information system, such as installing firewalls and other defenses that look into the information that is getting into and out of the system and filtering the traffic for IP addresses that are not authorized or allowed to get into the networks. The networks that stream information into the system also require having security protocols running to ensure that the information getting into and out of the system is safe and scanned for all threats before getting allowed to pass through. This is the wise thing to do, especially for the systems that keep sensitive information on them and cannot allow any threats to penetrate the information system’s structure.
Defenses are the best set-up through the use of communication protocols that are safe for the users and strong and proven to prevent unauthorized entry into the information systems. The information systems are also designed to be as effective as possible at keeping track of all entry and information access to keep a clear record of how the information has been moving into and out of the systems. This is something that any information system designed must be willing to consider as they set up the system for safe and secure use of information.
