The first is to use a standard list, supplied by your whitelist software vendor, of applications typical for your type of environment, which can then be customized to fit. The other is to have a system that you know is clear of malware and other unwanted software, and scan it to use as a model for a number of other machines.
The second method is a good fit for kiosks or other public-facing devices, which run a limited set of applications and don't require much by way of customization.
How does whitelisting software distinguish between unapproved and approved applications? The NIST guide breaks down the various attributes that can be used for this purpose:. Which attributes should be used and how much weight should be given to each is key to the art of whitelisting. For instance, if your whitelisting software allows any application with a specified file name or in a specified folder to execute, then all a hacker has to do bypass that protection is to place malware with that file name in the permitted location.
Specifying a precise file size or requiring a check against a cryptographic hash makes it harder to trick the whitelisting software, but this information would have to be updated in the whitelist every time the application file changes — whenever it's patched, for instance. And if patching is deferred because it potentially interferes with the whitelisting software, that can itself open up security holes. And as NIST points out, full-on applications aren't the only potential threat to a computer.
Whitelisting software needs to keep on top of various libraries, scripts, macros, browser plug-ins, configuration files, and, on Windows machines, application-related registry entries. Different vendors can deal with these with varying levels of granularity. Some whitelisting software can also whitelist specific behavior from even approved applications , which can come in handy if hackers manage to hijack them.
And whitelisting software should also integrate with the permissions structure of your operating system, whitelisting applications for some users like administrators but not others. Whitelisting isn't a one-size-fits-all tool, and it may not be an ideal endpoint solution for every computer under your purview. Calyptix Security suggests three scenarios where application whitelisting makes sense:. The truth is that whitelisting isn't a security panacea, and has to fit into a larger security landscape within your organization.
You'll still need anti-malware, endpoint protection, and perimeter defense systems to protect computers for which whitelisting isn't appropriate, or to catch what whitelisting misses. Most commercial operating systems have some whitelisting functionality built in, including Windows 10 and macOS.
App stores, of the sort used to install applications on iOS and Android devices, can be seen as a form of application whitelisting; they ostensibly only allow applications that are certified to be safe.
Most mobile management software allows more granular controls. But there are third-party vendors who offer more powerful or more granular application whitelisting software, which is often rolled into larger offerings or security suites. Popular examples include:. A last note here on two other contexts where you might see the word "whitelist" used in IT security: e-mail and IP addresses.
In these areas, whitelisting doesn't have quite the same meaning as it does with application whitelisting: obviously if you only allowed a narrowly defined list of email addresses to contact you, or computers from a specific list of IP addresses to reach your website, you would lost most of the utility of having a website or using email. In these contexts, "whitelisting" generally means taking manual steps to ensure that a certain IP address isn't blocked from accessing your site by some automated security process, or ensuring that email from a particular recipient doesn't go into your spam folder.
The latter is of course an obsession of email marketers, who are keen to share instructions on how to whitelist email addresses to make sure that their own email doesn't get deemed spam.
The former is a product of overzealous firewalls , which can sometime result in people being unable to access their own websites. cso online UNITED STATES. Here are the latest Insider stories. More Insider Sign Out. Sign In Register. Sign Out Sign In Register. NEW Insider PRO Learn More.

Though easy to setup initially, whitelisting can be burdensome as you will need to add new rules every time you install a new program or want to allow a program to run. Personally, I feel if you are willing to put the time and effort into using whitelisting, the chances of a computer infection damaging your computer becomes minimal.
This tutorial will walk you through setting up whitelisting using Software Restriction Policies so that only specified applications are able to run on your computer. Though this guide will be geared towards individual users, this same approach can be used in the enterprise by pushing these policies to a Windows domain. The method we use to create the application whitelist policy is through the Security Policy Editor. Unfortunately, this tool is not available in Home versions of Windows.
Therefore, you may want to instead use a program like CryptoPrevent to configure a blacklisting policy for you. To get started white listing your applications you need to open the Security Policy Editor, which configures the Local Security Policies for the machine. To do this, click on the Start button and then type secpol. msc into the search field as shown below. When secpol. msc appears in the search list, click on it to start the Local Security Policy editor.
If you are configuring this for a domain, then you should open the Group Policy Editor instead by using the command gpedit. This guide for the most part is designed for an individual computer, but can be used to create the same whitelisting policy using the Group Policy Editor. To begin creating our application whitelist, click on the Software Restriction Policies category. If you have never created a software restriction policy in the past, you will see a screen similar to the one below.
To create the new policy, right click on the Software Restriction Policies category and select the New Software Restriction Policies option as shown below. The first thing you need to do is configure the Enforcement section. This section allows us to specify general settings on how these restriction policies will be configured. To get started, click on the Enforcement object type as indicated by the blue arrow above. I suggest that you leave the settings like they are for now.
This allows you to create a strong policy, without the issues the may be caused by blocking DLLs. When you are done configuring these settings, click on the OK button. You will now be back at the main Software Restriction Policies window as shown in Figure 5. We now want to configure what file types will be considered an executable and thus blocked. To do this click on the Designated File Types object. This will open the properties window for the designated file types that will be considered as an executable and therefore blocked by the software restriction policy that you are creating.
Unfortunately, the above the list is not as exhaustive as you would like and includes an extension that should be removed. First, scroll through the above list of file extensions and remove the LNK extension from the list. To remove the extension, left-click on it once and then click on the Remove button.
If you do not remove this extension, then all shortcuts will fail to work after you create our whitelist. Now you want to add some extra extensions that are known to be used to install malware and ransomware. To add an extension, simply add it to the File Extension field and click on the Add button. When adding an extension, do not include the period.
For example, to exclude powershell scripts, you would enter PS1 into the field and click on the Add button. When you are done adding the above extensions, click on the Apply button and then the OK button. We will now be back at the main Software Restrictions Policy section as shown in Figure 8 below.
At this point, you need to configure the default policy that decides whether the file types configured in figure 7 will be automatically blocked or allowed to run. To do this, click on the Security Levels option as indicated by the blue arrow below.
When you double-click on the Security Levels category, you will be brought to the screen below that has three security levels you can apply to your software restriction policies. In order to select which level should be used, you need to double-click on the particular level and set it as the default. Below are the descriptions for each type of security level. Disallowed: All programs, other than those you allow by the rules you will configure, will not be allowed to run regardless of the access rights of the user.
Basic User: All programs should execute as a normal users rather than as an Administrator. Since you want to block all applications except those that you white list, you want to double-click on the Disallowed button to enter its properties screen as shown below. In the above properties screen, to make it so all applications will now be blocked by default, please click on the Set as Default button.
Then click on the Apply and OK buttons to exit the properties screen. We will now be back at the Security Levels list and almost every program will now be blocked from executing. For example, if you try to run Internet Explorer, you will receive a message stating that "This program is blocked by group policy.
Now that you have configured Windows to block all applications from running, you need to configure rules that allow your legitimate applications to run. The next section will explain how to create path rules so that the applications you wish to allow to run are whitelisted.
Those two directories are automatically whitelisted by two default rules that are created when you setup Software Restriction Policies. Obviously, in order to have a properly working machine you need to now allow, or whitelist, other applications. To do this, you need to create additional rules for each folder or application you wish to allow to run. While in the Local Security Policy editor, click on the Additional Rules category under Software Restriction Policies as shown below.
To do this, right-click on an empty portion of the right pane and click on New Path Rule as shown below. Then make sure the Security Level is set to Unrestricted , which means the programs in it are allowed to run. If you wish, you can enter a short description explaining what this rule is for in the Description field. When you are finished, the new rule should look like the one below.
When you are ready to add this rule, click on the Apply and then OK button to make that rule active. You now need to make new rules for other programs that you wish to allow to run in Windows.
In the next two sections, I have provided tips and and other types of rules that can be created to whitelist programs. I suggest you read it to take advantage of the full power of Software Restriction Policies. As always, if you need help with this process, please do not hesitate to ask in our tech support forums.
When adding a path rule that is a folder, it is important to note that any subfolder will also be included in this path rule. exe is allowed to execute as well. To make it easier when creating rules, it is also possible to use wild cards to help you specify what programs should be allowed to run.
When using wild cards, you can use a question mark? This rule would allow all files that end with. exe to execute, but not allow executables in subfolders to run. exe to run. It is also possible to use environment variables when creating path rules.
The growing emphasis on enterprise security has grown in the past few years. Application whitelisting is an important step in securing your IT infrastructure. Application whitelisting is the process of indexing, approving, and allowing the application s to be present on the computer system.
Unlike in the case of blacklisting where the system blocks an application or set of applications; the process of whitelisting allows a particular set of tools to run on the network.
Application whitelisting is more useful in environments which require individual systems to be more secured, due to data on these systems being highly confidential.
Application whitelisting allows you to have greater control over the type of apps installed inside the network. In a data-sensitive environment such as government organizations or projects involving sensitive data, this technology proves to be more helpful than application blacklisting. Application policy feature related to your mobile devices in application whitelisting tools allows you to minimize the risks associated with your own devices and applications installed on them.
Also, they provide a detailed analysis of these threats in the form of a report which can help you to shortlist, or reassess the whitelisted applications. Application Whitelisting tools also provide you a detailed application-based report. It helps you to understand the app-based activities such as data usage by an application, new installations of an app on a particular machine, uninstalling of an application from a device.
These tools provide the application upgrade notifications as well to help the organizations to keep up with the latest versions of the applications.
We will be discussing key application whitelisting tools in the succeeding content. Also Read: 10 Benefits of Mobile Device Management. Applocker whitelisting tool comes with Microsoft windows server editions, and windows operating systems with its enterprise and upgraded editions. Its rules can apply to an individual or also to a group of systems. You can also customize and set up different levels of enforcement as required.
PowerBroker whitelisting tool is another popular application whitelisting tool that supports Windows, Linux, and Mac too. This application is considered to have a more application control-based approach. It is more popular due to its key features, such as activity logging and privilege management. Its mobile policy features also help you out with the issues associated with the BYOD policy. PolicyPak integrates with Windows server and other OS editions mainly. It comes with three main editions, namely Group Edition, Cloud Edition, and MDM Edition.
You can also opt for a GP Compliance Reporter tool for whitelisting. PolicyPak Cloud Edition has a BYOD feature while Group Edition is more suited for smaller organizations. MDM Edition is similar to Cloud Edition but is useful with existing mobile device management services such as Workspace One, Intune, etc.
This tool is also useful with Windows. Its primary purpose is to keep sensitive data within the environment and help the organizations to secure data with more ease. It is known for its key features such as hierarchical access, endpoint security, mobile support, and the ability to main the privileges irrespective of locations.
It has other important features, such as monitoring of inactivity, data management, secured installation. It comes with an upgrade and notification feature for the uninstallation of the application as well. They provide an application whitelisting tool called Defendpoint, which is popular in practices such as BYOD, enterprise network security, endpoint security, malware detection, and report management.
Its core features also include application control, application management based on vulnerabilities, and security of ecosystem integration. It also comes with other key features, such as a local and global whitelisting database to comply with different regional data protection policies.
