What is seccomp profile?

Secure computing mode ( seccomp ) is a Linux kernel feature. You can use it to restrict the actions available within the container. The seccomp() system call operates on the seccomp state of the calling process. You can use this feature to restrict your application's access.

What is seccomp in Kubernetes?

Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6. 12. It can be used to sandbox the privileges of a process, restricting the calls it is able to make from userspace into the kernel.

How do I disable seccomp profile?

You may also disable the default seccomp profile by passing--security-opt=seccomp:unconfined on docker run.

What is the default path for seccomp?

The default seccomp profile for containers is a JSON file and can be viewed here: https://github.com/docker/docker/blob/master/profiles/seccomp/default.json.

What is the difference between SELinux and seccomp?

SELinux/AppArmor profiles allow administrators to control who accesses the system. Seccomp policies limit access to one's application. The container—Seccomp's functions restrict which syscalls a process can call to decrease the attack surface on the kernel.

How does seccomp work?

seccomp (short for secure computing mode) is a computer security facility in the Linux kernel. seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit() , sigreturn() , read() and write() to already-open file descriptors.

What is the difference between AppArmor and seccomp?

Both AppArmor and SecComp profiles are used to secure containers by limiting the actions they can perform. With SecComp, you restrict the available syscalls within the containers, and with AppArmor, you apply process confinements that enforce MAC rules.

What kind of restrictions does seccomp offer?

Simply put, seccomp restricts the system calls that a process can make. Since system calls are the way that users interact with kernel space this effectively means seccomp protects your kernel, which in turn protects your host and helps maintain the isolation expected in a containerised environment.

What is SELinux used for?

Security-Enhanced Linux (SELinux) is a security architecture for Linux® systems that allows administrators to have more control over who can access the system. It was originally developed by the United States National Security Agency (NSA) as a series of patches to the Linux kernel using Linux Security Modules (LSM).

What is the use of security profile?

A security profile is a group of permissions that map to a common role in a contact center. For example, the Agent security profile contains permissions needed to access the Contact Control Panel (CCP).

What is a characteristic of seccomp-BPF?

Seccomp-BPF is a more recent extension to seccomp, which allows filtering system calls with BPF (Berkeley Packet Filter) programs. These filters can be used to allow or deny an arbitrary set of system calls, as well as filter on system call arguments (numeric values only; pointer arguments can't be dereferenced).

What is the difference between AppArmor and seccomp?

Both AppArmor and SecComp profiles are used to secure containers by limiting the actions they can perform. With SecComp, you restrict the available syscalls within the containers, and with AppArmor, you apply process confinements that enforce MAC rules.

What are two types of security profiles?

The Firewalls come with two pre-defined security profiles, default and strict.

What are the three 3 features of security?

When we discuss data and information, we must consider the CIA triad. The CIA triad refers to an information security model made up of the three main components: confidentiality, integrity and availability. Each component represents a fundamental objective of information security.

Why do we need SecOps?

Goals of SecOps

Increase visibility of the security infrastructure for stronger security practices. Ensure that management has bought in at all levels to create a roadmap to increase and improve the organization's security.
