Implementing Mandatory Access Control with SELinux or AppArmor in Linux
Linux has built-in support for two types of Mandatory Access Control (MAC) systems: SELinux and AppArmor. Both systems add an additional layer of access control to the default Discretionary Access Control (DAC) that comes with Linux. In this article, we delve into the implementation of both systems, offering practical examples and their respective outputs. Understanding SELinux and AppArmor SELinux (Security-Enhanced Linux) is a Linux kernel security module that provides a mechanism for supporting access control security policies. It is a highly flexible MAC system that assigns labels to every object in the system (files, directories, ports, etc.) and ...
Read MoreHow to Mount and Unmount an ISO Image in Linux?
ISO images are popular file formats used to distribute and store entire file systems, including operating systems, software, and data. In Linux, mounting and unmounting ISO images is a common task that allows you to access the contents of the image as if it were a physical disk or drive. This functionality is particularly useful for installing software, creating virtual machines, or accessing specific files within an ISO image. In this article, we will explore the process of mounting and unmounting ISO images in Linux. We will cover the steps to mount an ISO image, verify the mount, and ...
Read MorePartition Allocation in Memory Management
Partition Allocation is a memory management technique where the operating system divides available memory into sections (partitions) and assigns them to processes. Each partition can hold one process, and the allocation method determines how processes are assigned to available memory spaces. This is fundamental to efficient memory utilization in operating systems. Types of Partition Allocation There are two main categories of partition allocation: Fixed Partition Allocation and Dynamic Partition Allocation. Fixed partitioning creates equal or unequal-sized partitions at system startup, while dynamic partitioning creates partitions of varying sizes based on process requirements. Partition ...

Read MoreNumerical on Disk
Numerics are essential for understanding the complex facets of disk storage since they offer a hands-on, practical method to grasp fundamental concepts. By exploring numerical examples, we can investigate how disk capacity, performance, and utilization are calculated, helping us understand the fundamentals of efficient storage management. Example − Consider a cloud service provider that offers file storage access to its customers. The service provider stores customer files, including documents, photos, and multimedia content, on disk storage. The disk storage system is built to support high data throughput and offers reliable file access. Disk Structure ...

Read MoreMethods in Interprocess Communication
Interprocess Communication (IPC) refers to the mechanisms that allow processes running on the same or different systems to exchange data and coordinate their activities. Since processes typically run in isolated memory spaces for security and stability, IPC provides the necessary channels for them to communicate when they need to share information or synchronize their operations. IPC is fundamental to modern operating systems and enables everything from simple parent-child process coordination to complex distributed computing systems. The primary goals of IPC are to facilitate secure, efficient, and reliable data exchange between processes while maintaining system integrity. Types of IPC ...
Read MorePath Name in File Directory
A path name in a file directory specifies the exact location of a file or directory within the hierarchical file system structure. It consists of directory names separated by delimiters − a forward slash (/) in Unix-based systems or a backslash (\) in Windows systems. Path names provide a roadmap from the root directory to the target file or folder. Types of Path Names There are two main types of path names used in file systems − Type Description Unix Example Windows Example Absolute Path Complete path from root directory ...
