Application whitelisting has been used in the online security world for quite some time now. For those who are more familiar with it, they know that it is the exact opposite of blacklisting. Everyone appears to be familiar with blacklisting since it is the technology that is found in all anti-virus programs found online.
Application Whitelisting versus Blacklisting in Singapore
With blacklisting, every file is checked to see if it is malicious. When it is found to be malicious, it is blocked from getting into the system and causing the damage. Application whitelisting is its opposite. The whitelist denies the entry of any application that is not known to be not malicious. This is known as the “default deny approach” which is known to work with ensuring security than the conventional blacklisting approach done by anti-virus programs for many good reasons. The best reason is that can prevent never before seen malicious codes also known as zero day attacks. This is because on day zero of releasing them, they won’t be recognized by blacklist databases.
Some misconceptions about whitelisting
Application whitelisting or AWL is hard to manage. The modern AWL is quite adept in tracking everything that goes on in the system when all the approved changes are implemented. The system also manages the whitelist database accordingly.
In AWL, there is no need to use a feature that can add or remove individual files from the whitelist. Users only have to approve upon learning of the entire changes being made like installing a new software. A legitimate AWL enables management to be non-intrusive as it can be.
It is also believed that anti-virus programs and application whitelisting won’t go well together. The truth is that for an in-depth defense strategy, both types of defense should go together. AWL would go against zero day attacks while the anti-virus would flag any malicious program that have been allowed in the whitelist database.
It is also believed that whitelisting will require an IT admin for changes in deploying the software and managing systems. If an AWL is managed well, it can work seamlessly with any software deployment and management system.
