Apparmor
AppArmor, found in Suse and Ubuntu Linux, is a system for letting applications run according to the principle of least privilege. This can be a useful for running forensic or other tools of questionable stability (what according to many means almost all tools) on data that may constructed with malicious intent against the specific tool, and mitigating the potential damage to the forensic process. While AppArmor works with static profiles, it does not intervene in communication of open files over unix sockets, that thus can be used to dynamically communicate authority to an (untrusted) AppArmor confined tool.
