What precautions should be taken to avoid creating a "tar bomb"?
To avoid creating a "tar bomb" when working with archiving and compression on Linux systems, it is important to take certain precautions. A "tar bomb" refers to a maliciously crafted archive file that, when extracted, can overwrite or flood a system's file system, causing potential damage or disruption. This can occur due to the way
How are discretionary access control (DAC) and least privilege used to implement privilege separation in Linux systems?
Discretionary Access Control (DAC) and least privilege are two key concepts used to implement privilege separation in Linux systems. Privilege separation is a important security measure that aims to limit the damage that can be caused by a compromised or malicious process. By employing DAC and least privilege, Linux systems can enforce access controls and
What are capabilities in Linux containers, and how do they help minimize the risk of unauthorized access or damage?
Linux containers are a popular technology used to deploy and run applications in a secure and isolated manner. Capabilities in Linux containers play a important role in minimizing the risk of unauthorized access or damage. In this context, capabilities refer to the privileges assigned to a process within a container, allowing it to perform specific
How does the use of seccomp help mitigate potential vulnerabilities in Linux containers?
Seccomp, short for secure computing mode, is a powerful feature in Linux that helps mitigate potential vulnerabilities in Linux containers. It provides a means of restricting the system calls that a process can make, thereby reducing the attack surface and limiting the potential damage that can be caused by exploiting vulnerabilities. Linux containers, such as
What are discretionary access control (DAC) and its limitations in terms of security risks?
Discretionary Access Control (DAC) is a security mechanism used in computer systems to regulate access to resources based on the identity and permissions of users. It allows the owner of a resource to determine who can access it and what actions can be performed on it. DAC is widely used in various operating systems, including
