💅 jetty_selinux(8) — the SELinux policy for jetty, bestie 💅

okay so this is the jetty_selinux(8) page, and it's all about the SELinux policy for the jetty processes. let's get into it 💖

✨ NAME ✨

jetty_selinux — Security Enhanced Linux Policy for the jetty processes

💖 DESCRIPTION 💖

SELinux keeps the jetty processes secured with flexible mandatory access control. periodt.

The jetty processes execute with the jetty_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier.

for example:

ps -eZ | grep jetty_t

🚪 ENTRYPOINTS 🚪

The jetty_t SELinux type can be entered via the jetty_exec_t file type.

the default entrypoint paths for the jetty_t domain are literally these:

/usr/share/jetty/bin/jetty.sh

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system.

you can see the context of a process using the -Z option to ps.

policy governs the access confined processes have to files. the SELinux jetty policy is very flexible, allowing users to set up their jetty processes in as secure a method as possible. slay.

the following process types are defined for jetty:

• jetty_t

Note bestie: semanage permissive -a jetty_t can be used to make the process type jetty_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. 👀

🎚️ BOOLEANS 🎚️

SELinux policy is customizable based on least access required. the jetty policy is extremely flexible and has several booleans that allow you to manipulate the policy and run jetty with the tightest access possible.

• if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

• if you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

• if you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

📂 MANAGED FILES 📂

The SELinux process type jetty_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. and psst — the process's UID still needs to have DAC permissions.

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type.

you can see the context of a file using the -Z option to ls.

policy governs the access confined processes have to these files. the SELinux jetty policy is very flexible, allowing users to set up their jetty processes in as secure a method as possible. iconic behavior honestly.

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the jetty. if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.

semanage fcontext -a -t jetty_exec_t '/srv/jetty/content(/.*)?'
restorecon -R -v /srv/myjetty_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 💅

the following file types are defined for jetty:

• jetty_cache_t — set files with the jetty_cache_t type, if you want to store the files under the /var/cache directory.
• jetty_exec_t — set files with the jetty_exec_t type, if you want to transition an executable to the jetty_t domain.
• jetty_log_t — set files with the jetty_log_t type, if you want to treat the data as jetty log data, usually stored under the /var/log directory.
• jetty_tmp_t — set files with the jetty_tmp_t type, if you want to store jetty temporary files in the /tmp directories.
• jetty_unit_file_t — set files with the jetty_unit_file_t type, if you want to treat the files as jetty unit content.
• jetty_var_lib_t — set files with the jetty_var_lib_t type, if you want to store the jetty files under the /var/lib directory.
• jetty_var_run_t — set files with the jetty_var_run_t type, if you want to store the jetty files under the /run or /var/run directory.

Note: file context can be temporarily modified with the chcon command. if you want to permanently change the file context you need to use the semanage fcontext command. this will modify the SELinux labeling database. you will need to use restorecon to apply the labels. 🔥

🛠️ COMMANDS 🛠️

• semanage fcontext can also be used to manipulate default file context mappings.
• semanage permissive can also be used to manipulate whether or not a process type is permissive.
• semanage module can also be used to enable/disable/install/remove policy modules.
• semanage boolean can also be used to manipulate the booleans.
• system-config-selinux is a GUI tool available to customize SELinux policy settings.
