What is AppArmor profile?

AppArmor profiles are simple text files. Absolute paths as well as file globbing can be used when specifying file access.

How do I find my AppArmor profile?

AppArmor profiles are text files located under /etc/apparmor. d/ directory. The files are named after the full path to the executable they profile, but replacing the “/” with “.”. The following is the Apparmor profile file for usr.

What is the default AppArmor profile?

The default AppArmor profile is attached to a program by its name, so a profile name must match the path to the application it is to confine. This profile will be automatically used whenever an unconfined process executes /usr/bin/foo .

What is the difference between SELinux and AppArmor?

AppArmor works by granting access first, then applying restrictions. SELinux, however, restricts access to all applications by default and grants access only to users that present the proper certifications. Uses security profiles based on paths. Uses security policies based on file labels.

Is AppArmor necessary?

AppArmor is a Mandatory Access Control (MAC) system, implemented upon the Linux Security Modules (LSM). AppArmor, like most other LSMs, supplements rather than replaces the default Discretionary Access Control (DAC).

How do I enable AppArmor in Linux?

How to enable/disable. If AppArmor is not the default security module it can be enabled by passing security=apparmor on the kernel's command line. If AppArmor is the default security module it can be disabled by passing apparmor=0, security=XXXX (where XXXX is valid security module), on the kernel's command line.

What is Docker AppArmor?

AppArmor is a Linux kernel security module that you can use to restrict the capabilities of processes running on the host operating system. Each process can have its own security profile. The security profile allows or disallows specific capabilities, such as network access or file read/write/execute permissions.

Can I disable AppArmor?

To disable AppArmor in the kernel to either: adjust your kernel boot command line (see /etc/default/grub) to include either. * 'apparmor=0' * 'security=XXX' where XXX can be "" to disable AppArmor or an alternative LSM name, eg.

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.

Where is Docker default profile?

Docker automatically generates and loads a default profile for containers named docker-default . The Docker binary generates this profile in tmpfs and then loads it into the kernel. Note: This profile is used on containers, not on the Docker Daemon.

What is the default security profile in Docker?

The default seccomp profile provides a sane default for running containers with seccomp and disables around 44 system calls out of 300+. It is moderately protective while providing wide application compatibility.

Should I remove AppArmor?

It's a security tool that restricts applications to a constrained set of resources. If the application is then compromised, it only has access to that set of resources and not to the whole system. In other words, unless you know what you're doing, you almost certainly don't want to remove AppArmor from Ubuntu.

Can I remove AppArmor?

23.5 Deleting an AppArmor Profile

Go to the AppArmor directory with cd /etc/apparmor. d/. Enter ls to view all the AppArmor profiles that are currently installed. Delete the profile with rm profilename.

Can I disable AppArmor?

To disable AppArmor in the kernel to either: adjust your kernel boot command line (see /etc/default/grub) to include either. * 'apparmor=0' * 'security=XXX' where XXX can be "" to disable AppArmor or an alternative LSM name, eg.

What is AppArmor service?

AppArmor is a Linux Security Module implementation of name-based mandatory access controls. AppArmor confines individual programs to a set of listed files and posix 1003.1e draft capabilities. AppArmor is installed and loaded by default.
