Secure your Go builds with AppArmor

If you have a Linux system with AppArmor, you can use it to secure your Go builds.

First install Go in /usr/local/go as in the the instructions.

Then add this file to /etc/apparmor.d, replace ${HOME} with your home directory.

#include <tunables/global>

profile go /usr/local/go/bin/go {
    #include <abstractions/base>
    #include <abstractions/consoles>
    /tmp/ r,
    /tmp/** rwkix,
    @{PROC}/** r,
    /sys/** r,
    /dev/** r,
    /etc/** r,
    /usr/** r,
    /bin/** ix,
    /usr/bin/** ix,
    /usr/libexec/** ix,
    /usr/lib/** ix,

    /usr/local/go/** rix,

    owner @{HOME}/.config/go/** rw,
    owner @{HOME}/.cache/go-build/** rwkix,
    owner @{HOME}/.cache/JetBrains/IntelliJIdea*/tmp/GoLand/** rwkix,
    owner @{HOME}/.cache/JetBrains/IntelliJIdea*/coverage/** rwk,
    owner @{HOME}/.local/share/JetBrains/IntelliJIdea*/go-plugin/** rix,
    owner @{HOME}/.config/dlv/** r,
    owner @{HOME}/.gitconfig r,
    owner @{HOME}/.gitignore r,
    owner @{HOME}/go/** rwkl,
    owner @{HOME}/go/bin/* rwklix,
    owner @{HOME}/src/** rwk,

    /etc/resolv.conf r,
    @{PROC}/sys/net/** r,
    /run/systemd/resolve/** r,
    network,

    signal (receive) set=(int,term,kill),

    ptrace,
}

profile go-fmt /usr/local/go/bin/gofmt {
    #include <abstractions/base>
    #include <abstractions/consoles>
    /tmp/** rwkix,

    /usr/local/go/** rix,

    owner @{HOME}/.config/go/** rw,
    owner @{HOME}/.cache/JetBrains/IntelliJIdea*/tmp/GoLand/** rwk,
    owner @{HOME}/go/** rwk,
    owner @{HOME}/src/** rwk,

    signal (receive) set=(int,term,kill),
}

profile go-bin ${HOME}/{go/bin/*,.cache/go-build/**,.cache/JetBrains/IntelliJIdea*/tmp/GoLand/*} {
    #include <abstractions/base>
    #include <abstractions/consoles>
    /etc/** r,
    /bin/** ix,
    /usr/bin/** ix,
    /tmp/ r,
    /tmp/** rwk,

    /usr/local/go/** rix,

    owner @{HOME}/.config/go/** r,
    owner @{HOME}/.cache/go-build/** rix,
    owner @{HOME}/.cache/JetBrains/IntelliJIdea*/tmp/GoLand/** rix,
    owner @{HOME}/go/** r,
    owner @{HOME}/go/bin/* rix,
    owner @{HOME}/src/** r,

    /etc/resolv.conf r,
    @{PROC}/sys/net/** r,
    /run/systemd/resolve/** r,
    network,

    signal (receive) set=(int,term,kill),

    ptrace (tracedby, readby) peer=go,
}

Then run sudo service apparmor reload to activate it (it will be loaded automatically on boot). This is tested un Ubuntu desktop 24.04. It will also enable use of the Go plugin to IntelliJ IDEA.
