dirsrv_snmp_selinux(8)

Hii bestie! You’re reading the dirsrv_snmp_selinux(8) page from the SELinux Policy dirsrv_snmp manual — yes, we’re doing SELinux lore today 💅✨

💖 NAME 💖

dirsrv_snmp_selinux — Security Enhanced Linux Policy for the dirsrv_snmp processes. Periodt.

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the dirsrv_snmp processes via flexible mandatory access control.

The dirsrv_snmp processes execute with the dirsrv_snmp_t SELinux type. Wanna check if you have these processes running? Execute the ps command with the -Z qualifier, like this:

ps -eZ | grep dirsrv_snmp_t

🦋 ENTRYPOINTS 🦋

The dirsrv_snmp_t SELinux type can be entered via the dirsrv_snmp_exec_t file type.

The default entrypoint paths for the dirsrv_snmp_t domain are the following:

/usr/bin/ldap-agent, /usr/bin/ldap-agent-bin

👑 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. SELinux dirsrv_snmp policy is very flexible allowing users to setup their dirsrv_snmp processes in as secure a method as possible.

The following process types are defined for dirsrv_snmp:

• dirsrv_snmp_t

Note: semanage permissive -a dirsrv_snmp_t can be used to make the process type dirsrv_snmp_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. dirsrv_snmp policy is extremely flexible and has several booleans that allow you to manipulate the policy and run dirsrv_snmp with the tightest access possible.

• daemons_dontaudit_scheduling — If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on this boolean. Enabled by default. Command: setsebool -P daemons_dontaudit_scheduling 1
• fips_mode — If you want to allow all domains to execute in fips_mode, you must turn on this boolean. Enabled by default. Command: setsebool -P fips_mode 1
• nscd_use_shm — If you want to allow confined applications to use nscd shared memory, you must turn on this boolean. Enabled by default. Command: setsebool -P nscd_use_shm 1

🎀 MANAGED FILES 🎀

The SELinux process type dirsrv_snmp_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Quick reminder: 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. SELinux dirsrv_snmp policy is very flexible allowing users to setup their dirsrv_snmp processes in as secure a method as possible.

✨ STANDARD FILE CONTEXT ✨

SELinux defines the file context types for the dirsrv_snmp, 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 dirsrv_snmp_exec_t '/srv/dirsrv_snmp/content(/.*)?'
restorecon -R -v /srv/mydirsrv_snmp_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies stay winning 🧚

The following file types are defined for dirsrv_snmp:

• dirsrv_snmp_exec_t — Set files with the dirsrv_snmp_exec_t type, if you want to transition an executable to the dirsrv_snmp_t domain.
  • Paths:
    • /usr/bin/ldap-agent
    • /usr/bin/ldap-agent-bin
• dirsrv_snmp_var_log_t — Set files with the dirsrv_snmp_var_log_t type, if you want to treat the data as dirsrv snmp var log data, usually stored under the /var/log directory.
• dirsrv_snmp_var_run_t — Set files with the dirsrv_snmp_var_run_t type, if you want to store the dirsrv snmp 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. No shortcuts, bestie 💅

💅 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.
