Description: Under Supervision refers to a monitored state of permissions in the context of computer security, specifically in operating systems that implement access controls. This term implies that the actions of a process or application are subject to a set of rules and restrictions that limit its ability to interact with the system and other resources. The idea is to prevent unwanted or malicious behaviors, ensuring that applications only perform the operations for which they have been authorized. Under Supervision is a key feature in security systems, where a security profile is defined that specifies what resources an application can access and what actions it can perform. This not only protects the system from potential vulnerabilities but also helps maintain data integrity and user privacy. In an environment where cyber threats are becoming increasingly sophisticated, the concept of Under Supervision becomes essential to ensure an adequate level of security and control over the applications running on a system.
History: AppArmor was developed by Immunix in 2003 as a security solution for Linux systems. In 2009, it was integrated into the Linux kernel, allowing for broader adoption. Over the years, AppArmor has evolved to provide easier management of security profiles, facilitating its implementation across various Linux distributions.
Uses: Under Supervision is primarily used in server environments and critical systems where security is paramount. It allows administrators to define security profiles for specific applications, limiting their access to system resources and reducing the risk of exploiting vulnerabilities. It is also used in development environments to test applications in a controlled setting.
Examples: A practical example of Under Supervision is the use of access control mechanisms on a web server, where access of an application server can be restricted to only the necessary files and directories, preventing it from accessing sensitive information or performing unauthorized actions. Another example is in desktop environments, where it can be applied to web browsers to limit their access to system resources.
