In the era of growing cyber security threats, securing sensitive data has become an indispensable issue for both individuals and organizations. Controlled Folder Access (CFA) is one of the most effective ways to deal with scenarios involving ransomware and other malicious attacks. This article provides a comprehensive guide on what CFA is all about, its importance implementation and best practices that can be used to enhance it.
What is Controlled Folder Access ?
Controlled folder access is a security feature introduced in Windows 10 and continued in Windows 11. It is designed to protect important folders and files from unauthorized changes made by unknown or potentially malicious applications. When enabled Controlled folder access monitors and restricts access to specified folders thereby adding an extra layer of protection against ransomware and other types of malware.
This Windows 10 introduced security feature aims at protecting valuable data by limiting access to certain folders. It does this by monitoring protected folders thereby stopping unauthorized applications from altering any files within these folders. This ensures that ransomware attacks, data breaches or any other forms of malware induced data loss are reduced using proactive approaches
By default Controlled folder access protects system folders that are considered crucial for the proper functioning of your operating system. These include folders such as Documents, Pictures, Videos, Music, Favorites and Desktop. However you can also add additional folders to the controlled folder list allowing you to safeguard your personal data and other important files.
Whenever an application attempts to make unauthorized changes or access files within the protected folders. Controlled folder access will generate a notification in Windows Security. You can review these notifications and if you determine that the application should be allowed access, you can add it to the list of allowed apps. This way only trusted applications can modify or access files within the protected folders.
Controlled folder access is a proactive security measure that helps prevent unauthorized modifications to your important data adding an extra layer of protection to your files and folders.
