What Does Whitelisting Mean?

When you implement application whitelisting, you can considerably reduce the chances of a security breach. Provided you carefully establish the list of allowed applications and regularly update it, an incident is less likely. With stricter control over third-party tools comes a significant reduction in potential attack vectors. Whitelisting also inherently increases the granularity of access control, which (in addition to improving security) also reduces the likelihood of costly human errors. At its core, a whitelist is a compilation of approved entities—be they email addresses, IP addresses, domain names, applications, or websites—that are explicitly allowed permission or access within a system or network.

What is Application Whitelisting?

  1. In some ways, the use of antivirus software is similar to application blacklisting.
  2. Nobody, though, is suggesting that you should dump all other lines of security and do only whitelisting.
  3. The 2024 Global Threat Report unveils an alarming rise in covert activity and a cyber threat landscape dominated by stealth.
  4. Another benefit to using application whitelisting is that doing so can simplify software license compliance.

However, maintaining a high level of security requires balancing its benefits against the potentially reduced productivity and performance of staff. Industries that are highly regulated must be even more sensitive as they navigate this equation. Keeping a whitelist up to date can be exhausting, requiring constant evaluation and immediate reaction from administrators.

A whitelist is a security list that provides access to only pre-approved programs, IPs, or email addresses. Whatever is on the “list” gets access to system resources, whereas the rest are denied access. James Tarala, an instructor for security training organization SANS Institute and one of the principal contributors to the Council on CyberSecurity, said that whitelisting can be based on several things. This includes the name of the executable, a digital signature of the program being executed, or the location on the computer’s file system where the executable resides.

One more possible solution is to look for a vendor that keeps up with patch releases on your behalf and automatically updates whitelists to reflect newly released patches. Of course, this approach might be slightly less desirable since the vendor may whitelist a patch that the how to buy fantom crypto organization does not wish to deploy.

No matter which type of whitelist you craft, here are some major benefits of having one. “Even if malware already exists on a workstation, what is illicit cryptocurrency mining it will be blocked when it attempts to call home,” said Sjouwerman.

Another best practice is to be careful about how you define whitelisted applications. However, using this approach may make the organization vulnerable to ransomware attacks and other threats. Depending on an application whitelisting tool’s reporting capabilities, such a tool may help the organization to determine which users are engaging in risky behavior. Some application whitelisting tools are able to create reports detailing which users have attempted to install or run unauthorized applications, as well as any malware that has been detected.

Where whitelisting fits into a security program

This helps to stop the execution of malware, unlicensed software, and other unauthorized software. This publication is intended to assist organizations in understanding the basics of application whitelisting. It also explains planning and implementation for whitelisting technologies throughout the security deployment lifecycle.

Often, a user or department requests access to a specific approved application or to a remote server or service not accessible from corporate devices or the corporate network. When a destination or application is put on a whitelist, it is considered safe, and access to the remote destination, application or service is granted. Instead of listing all the potential bad stuff you don’t want to let in, it’s simpler to create a shorter list of applications and processes that are authorized to run. Application whitelisting is one of the more stringent security measures an organization could undertake.

By providing centralized control for all your resources, whitelisting provides an added layer of security to high-risk environments where threats such as phishing and ransomware are rampant. Whitelisting provides a middle ground for such situations where you want your employees to stay productive while preserving your corporate data as well. By limiting your employee’s access to a preset list of a university for a changing world websites and applications, you can prevent them from accessing unsafe resources. Even the gaming world requires whitelists to prevent unauthorized players from accessing your servers.
