CompTIA Linux+ XK0-006 (V8) Practice Question

A system administrator conducted a security audit and discovered that an executable file, /usr/local/bin/legacy_app, has the SUID bit set. This is considered an unnecessary security risk. The current permissions are displayed as rwsr-xr-x. Which of the following commands should be used to specifically remove the SUID permission while leaving the other permissions unchanged?

  • chattr -s /usr/local/bin/legacy_app

  • setcap -r /usr/local/bin/legacy_app

  • chmod u-s /usr/local/bin/legacy_app

  • chown user:user /usr/local/bin/legacy_app
