Prevent Cyber-attacks with Application Whitelisting

Cybercriminals are growing and using more sophisticated attacks every day. Antivirus software alone cannot protect your IT systems.  Cybersecurity experts recommend using a layered approach to security and in this article, we will discuss one of these layers of protection that can dramatically increase the security to your IT network.

At Triella, we continuously review the threats that affect our clients and implement systems to help to secure our client systems.  Application whitelisting is just the latest in protections offered in our security portfolio.

Application Whitelisting

Application whitelisting is one of the best security protocols to fight against a broad variety of cyber-attacks. This technique is particularly useful for blocking ransomware and other software base attacks knows as Malware.

How does it work?

Application Whitelisting is a way of controlling which software can run in your environment and preventing the installation or execution of unapproved applications.  It monitors including PowerShell and any other scripts that are required to run the software. Any attempt to alter these files or run a new process that are not permitted within the software will be blocked or will require permission from administration.

For example, you may use PowerShell for regular work within the firm however there is no need for PowerShell to connect to the Internet for example.  Therefore you can allow PowerShell to run but if an attempt is made to use PowerShell to access resources on the internet, that will automatically be blocked.

How is it different from Antivirus software?

Antivirus and Application Whitelisting’s differ in that Antivirus programs blocks all known harmful activities and permits the rest. However, application whitelisting will work by permitting identified actions and preventing all others. Whitelisting is a proactive approach rather than a reactive approach, which allows the running of only pre-approved software.

Other advantages of implementing Application Whitelisting include the ability to control the usage of infrastructure resources and to reduce conflicts and crashes which sometimes arise from unknown applications.

Initial Implementation of Application Whitelisting can be quite challenging, especially when identifying applications that various users/ departments need to function daily. However, once you implement it, you do not require a significant effort to maintain it and your systems are protected from malware and ransomware attacks.
