4 Reasons Why Application Whitelisting Makes Sense
Application whitelisting (AWL) is a software designed to keep your computer system safe and secure, most people are aware of blacklisting as it is the technology used in nearly all the antivirus software on the market today. AWL is the opposite of blacklisting software, blacklisting application monitors files for malicious content and if found stops them from opening, whereas, in AWL the administrator creates the whitelist and instead of scanning for harmful viruses, whitelisting applications only allow known and trusted sites to open.
- More Secure
The general consensus on AWL is that it is safer and more secure than blacklisting, the reason for this is that blacklisting rejects an application that it considers to be dangerous, in contrast, AWL only enables trusted applications to run, it completely blocks any other programme which it does not recognise or deem safe. There are some types of viruses that cannot be stopped by blacklisting because they have not yet been recognised so they could potentially cause damage. However, this is not possible using application whitelisting as all software which is not whitelisted is not allowed to run.
- Uses Less Resources
AWL adopts the approach of denying access for every application not known to the system,
AWL allows administrators to populate a database with known, trusted applications that have permission to access a system, this means when new applications attempt to gain access their signatures only need to be compared to the signatures already in the database. In contrast, blacklisting has to read entire files and determine whether they are safe or not, this includes searching for signatures of all previously known malware variants within the files, all of which requires far more CPU cycles.
Application whitelisting is far more flexible when it comes to controlling access to your system, administrators can update the database of trusted applications as they see fit, this ensures the system runs with maximum efficiency. AWL also allows administrators to remove previously trusted applications, which have become compromised from the whitelist database.
- Easily Managed by IT Administration
As soon as the whitelisting system is working, it can be easily managed by a competent, knowledgeable administrator, this individual will be responsible for monitoring and updating the system whenever it is needed. Some of the tasks that you be carried out consist of modernizing the system to ensure it is running correctly, assessing any problems with the system and dealing with it appropriately, and installing the whitelisting to any other platforms if required. Furthermore, technicians should conduct a variety of tests to ensure the software is working properly and everything is up to date.
Application whitelisting is an excellent structure which is intended to keep your computer working to the best of its ability, it provides a security system that enables administrator to decide exactly what type of software is allowed access to your system, if you value security, AWL makes sense.
