Description: The term ‘Low Security Level’ refers to minimal or basic security measures, implying that operating systems or applications do not implement robust controls to protect system data and resources. In the context of computing, this relates to the distinction between ‘Kernel Mode’ and ‘User Mode’. In ‘Kernel Mode’, the operating system has full access to all hardware resources and can execute any instruction, making it a high-privilege environment. On the other hand, ‘User Mode’ is a restricted environment where applications have limited access to system resources, helping to prevent a malicious or faulty program from affecting the operating system or other programs. A low security level in general can lead to critical vulnerabilities, as any failure in this mode can compromise the integrity of the entire system. Therefore, it is essential for computing systems to implement adequate security measures to protect both ‘Kernel Mode’ and ‘User Mode’, ensuring that running applications cannot access sensitive resources without proper authorization.
