Learning About Application Whitelisting
Application whitelisting is basically a practice where an index of software applications that are approved is specified previously. These software applications are permitted to be present and at the same time be active on the computer system. The main aim of whitelisting is the protection of both the computers and networks from applications that are potentially harmful in nature.
A whitelist can be considered as an index of approved entities in general. In information security, application whitelisting simply works the best in the environments that are centrally managed where the systems are constantly subjected to workload.
Application whitelisting versus application blacklisting
In contrast to the technologies that use application blacklisting which prevents all the unwanted programs from being executed, application whitelisting is much more restrictive and allows running only the programs which have been explicitly permitted to run. It is still not very clear among the security experts that application whitelisting is better or application blacklisting is better. One who favors blacklisting is the viewpoint that whitelisting is very complex in nature and also very difficult to manage as well. The initial compilation of the application whitelisting requires the detailed information about all the tasks of the users and all the applications which are needed for performing the tasks. The maintenance of this list is not easy because of the rising complexity and interconnections of various applications and business processes.
On the other hand, one who favors application whitelisting is the viewpoint that it is extremely simple and convenient. It gives full worth of the time & effort that is required to protect the systems and prevent the harmful programs from entering the networks. The design of whitelisting is much better which gives explicit protection against harmful software as compared to blacklisting which offers protection that is a bit looser.
