The Truth about Application Whitelisting

Application whitelisting is a specialty technology primarily designed to keep designated computer systems safe from any invading software, including the damage caused by the intrusion of malware. This will work together with application blacklisting to stop any known viruses, malware, and more from entering your system and potentially threatening the security of important data held there. As a business, you have an obligation to protect the personal information of your clients as well as the private information held by your own company and the combined forces of whitelisting and blacklisting should make this possible.


Blacklisting is limited in that it may only stop a virus or otherwise dangerous piece of code from infecting your computer if it is listed as a known danger to your computer. With whitelisting, you get to choose exactly which applications may be run on your computer and any connected computers so that absolutely anything beyond that list of approved applications cannot run at all. If an unauthorised application should attempt to run on your computer, you will receive immediate notification and a request for permission or the application may be immediately rejected, depending on your software.


Whitelist application solutions are generally considered to be more secure than blacklisting solutions because they are much easier to use and do not rely on frequently updated data to keep your system protected. This is also due to the existence of a serious problem called “zero day” attacks that completely evade blacklisting and directly attack your computer. Zero day attacks occur when a previously unknown or undisclosed vulnerability within an existing software is discovered and then exploited by those with bad intent. The first day of this attack is called “day zero”.

In short, blacklisting will stop any known problems from causing you any trouble or putting you and your clients in danger while application whitelisting will keep anything missed by the former from getting through your firewalls. Although a whitelisting software may sound as if it is enough, in theory, to protect your systems on its own, it is never too much to add a reputable blacklisting software to the equation. Your company, its staff, and your clients rely on the data, such as passwords, credit information, and more, that is collected in the system remaining private and having both of these types of software on hand will protect everyone’s interests.


The best way for you to utilise whitelisting is to contact a reputable supplier and then work with them to create an approval list unique to your company. As you learn of new applications that you need for your work or that may improve certain aspects of the work, you may easily add them to the list without any lost time. The result will be a great service designed to offer you peace of mind and lasting security without any unnecessary complexity in regards to the way you manage the software over the long run. Your company will be safe and your clients will feel greater trust in your capabilities as a whole and will be more likely to return for further assistance.
