WHAT IS APPLICATION CONTROL AND HOW TO BLOCK APPS

What is a software application?

Applications, popularly referred to as apps, are ubiquitous. These software programs that are designed to perform a specific function or set of functions for users are found on computers and personal devices on a consumer and enterprise level.

Whether the application is a small program designed for consumer use or an enterprise-level application that supports organizations such as businesses or governments, controlling it can be necessary to improve security, confidentiality, integrity, and productivity.

Application control definition: What is application control?

Application controls are security measures used to manage the use of specific applications on a system, such as a cloud computing platform or a mobile device. They can block apps from being installed on a device or prevent certain apps from being used. Administrators typically use application controls to block apps that they consider to be unsafe or inappropriate.

Application controls can also be leveraged to block access to apps that lead to unsafe websites. Blocking such apps can be more practical than blocking IP addresses, as Austria discovered in late 2022.

There are a few different ways and technologies that implement application controls. For example, your operating system should have application control settings. In addition, organizations may use a robust firewall or third-party software designed for application control.

An application control blacklist, also known as a blocklist, is a list of apps that are denylisted from use on a system. Conversely, an application control whitelist, also known as a safelist, is a list of apps allowed on a system.

Application controls can be beneficial in a few different ways. They can help to improve security by preventing unauthorized apps from being used on a device. They can also help improve productivity by ensuring that only work-related apps are available to users.

If you’re considering implementing application controls, there are a few things to keep in mind:

1. Decide what apps you want to allow or block.
2. Decide how you want to implement the controls.
3.  Run tests to ensure your application controls are working as intended.

How does application control work?

Application control works by allowing administrators such as network specialists in organizations or parents at home to manage application usage on a system or device. Home users may use application control tools built into their devices, or they may download third-party software. But application control systems for organizations are more advanced.

Businesses use application control tools that prevent software from executing in a manner that puts data, workflow, or operational integrity at risk. Typical application control technology in an organization works by matching network traffic flow with predefined condition models. Network administrators may categorize applications by security risk level, resource usage, and the purpose they serve. Programs can be prioritized by these classifications.

Common application control features include:

1. Identification.
2. Authentication.
3. Authorization.
4. Completeness and validity checks.
5. Input and forensic controls.

App blocking definition: What is app blocking?

App blocking is the process of stopping an app from running on a device. The process can have different applications. For example, a parent can use app blocking to prevent their children from using certain apps during class, or a network administrator may use the tool to help workers stay focused by blocking apps that are not work-related.

There are several ways to block apps, including using apps that block other apps, setting up restrictions on devices, or using third-party software that blocks apps.

How to block apps

Parents can use third-party or built-in tools on Windows, macOS, Android, and iOS to block apps. Meanwhile, organizations can use enterprise-level third-party app-blocking software to prevent users from downloading apps on Android, Apple, and Windows devices. Some firewalls also allow enterprises to block apps from usage.

How to block apps on computer

You can use a third-party program to block apps on a computer or the tools in the operating system. Organizations can use tools like the application control security technology baked into certain next-generation firewalls (NGFWs). You can read more about how a next-generation firewall works to learn more.

Why block apps in your organization

As remote working and BYOD become commonplace, cybersecurity incidents are rising. So, what is BYOD? Well, BYOD means Bring Your Own Device. And although convenient, BYOD creates risks.

With employees bringing their own devices to work, organizations want to protect their resources from endpoint security concerns, especially with some employees clicking on everything with gay abandon.

Application control helps secure the data used or transferred between applications in an organization’s system. Organizations can stop staff from installing potentially malicious applications.

Blocking apps may also improve productivity and workflow by restricting employee access to inappropriate or distracting applications such as Voice over Internet Protocol (VoIP), games, and instant messaging.

We also recommend that organizations invest in endpoint protection to ensure the safety of laptops, smartphones, tablets, and other endpoints from different types of malware, such as zero-day exploits, ransomware, and other threats. Pick a lightweight endpoint security tool that delivers accurate verdicts, offers simplified management, stops malware outbreaks, and saves your enterprise money by reducing downtime.

Application controls examples: Types of application controls

Input controls

Input controls manage data inputs. An input control tool stops users from feeding unverified data into the system.

Output controls

Output controls manage data outputs, verifying data before it exits a system. Output controls may verify that data is correct, complete, and transferring to the right target.

Processing controls

Processing controls ensure that data is processed acceptably before it enters into a system. A validity check, for example, ensures that all processed data is correct.

Access controls

Granting access to users on a need-to-know basis is critical to security. Access controls ensure that users are authorized to perform their actions, such as viewing information or modifying inputs.

Integrity controls

The integrity of data input is maintained by integrity controls. These controls outline rules, such as the format of a date or the type of characters in an input.

Application control features and benefits: Which features are provided by application control?

1. Authenticate software to ensure that only verified apps are usable and reduce cybersecurity threats.  
2. Policies for applications set the right guidelines to enable a zero-trust security architecture.
3. Improved network visibility to identify potential red flags like an incoming data breach.
4. Protection against exploits that hackers may use to target apps.
5. Streamline networking in the corporate network with latency-sensitive apps prioritized for better performance.

Application controls audit: How to audit your application controls

While application control audit steps vary by organization, there are some general rules to follow:

1. Identify all the controls at your disposal.
2. Assess the control design.
