This security feature, integrated into the Windows operating system, allows administrators and users to manage which applications and browsers can execute on a system. It includes options for blocking potentially unwanted applications (PUAs), controlling web browser functionality, and managing code integrity settings. An example is configuring the system to only allow digitally signed applications from trusted publishers to run, thereby mitigating the risk of malware infections.
Its significance lies in bolstering system security and mitigating risks associated with malicious software and untrusted code. Historically, organizations have relied on third-party solutions for application control. This integrated feature provides a native, centralized approach, streamlining security management, reducing the attack surface, and ensuring compliance with security policies. By limiting the execution of unauthorized or risky software, it reduces the likelihood of malware infections, data breaches, and other security incidents. This contributes to enhanced productivity and minimizes downtime associated with security remediation.
