## The purpose of these rules is to meet the stig auditing requirements ## These rules depends on having 10-base-config.rules & 99-finalize.rules ## installed. ## NOTE: ## 1) if this is being used on a 32 bit machine, comment out the b64 lines ## 2) These rules assume that login under the root account is not allowed. ## 3) It is also assumed that 1000 represents the first usable user account. To ## be sure, look at UID_MIN in /etc/login.defs. ## 4) If these rules generate too much spurious data for your tastes, limit the ## the syscall file rules with a directory, like -F dir=/etc ## 5) You can search for the results on the key fields in the rules ## ## ## (GEN002880: CAT II) The IAO will ensure the auditing software can ## record the following for each audit event: ##- Date and time of the event ##- Userid that initiated the event ##- Type of event ##- Success or failure of the event ##- For I&A events, the origin of the request (e.g., terminal ID) ##- For events that introduce an object into a user’s address space, and ## for object deletion events, the name of the object, and in MLS ## systems, the object’s security level. ## ## Things that could affect time -a always,exit -F arch=b32 -S adjtimex,settimeofday,stime -F key=time-change -a always,exit -F arch=b64 -S adjtimex,settimeofday -F key=time-change -a always,exit -F arch=b32 -S clock_settime -F a0=0x0 -F key=time-change -a always,exit -F arch=b64 -S clock_settime -F a0=0x0 -F key=time-change # Introduced in 2.6.39, commented out because it can make false positives #-a always,exit -F arch=b32 -S clock_adjtime -F key=time-change #-a always,exit -F arch=b64 -S clock_adjtime -F key=time-change -w /etc/localtime -p wa -k time-change ## Things that affect identity -w /etc/group -p wa -k identity -w /etc/passwd -p wa -k identity -w /etc/gshadow -p wa -k identity -w /etc/shadow -p wa -k identity -w /etc/security/opasswd -p wa -k identity ## Things that could affect system locale -a always,exit -F arch=b32 -S sethostname,setdomainname -F key=system-locale -a always,exit -F arch=b64 -S sethostname,setdomainname -F key=system-locale -w /etc/issue -p wa -k system-locale -w /etc/issue.net -p wa -k system-locale -w /etc/hosts -p wa -k system-locale -w /etc/hostname -p wa -k system-locale -a always,exit -F dir=/etc/NetworkManager/ -F perm=wa -F key=system-locale ## Things that could affect MAC policy -a always,exit -F dir=/etc/selinux/ -F perm=wa -F key=MAC-policy ## (GEN002900: CAT III) The IAO will ensure audit files are retained at ## least one year; systems containing SAMI will be retained for five years. ## ## Site action - no action in config files ## (GEN002920: CAT III) The IAO will ensure audit files are backed up ## no less than weekly onto a different system than the system being ## audited or backup media. ## ## Can be done with cron script ## (GEN002700: CAT I) (Previously – G095) The SA will ensure audit data ## files have permissions of 640, or more restrictive. ## ## Done automatically by auditd ## (GEN002720-GEN002840: CAT II) (Previously – G100-G106) The SA will ## configure the auditing system to audit the following events for all ## users and root: ## ## - Logon (unsuccessful and successful) and logout (successful) ## ## Handled by pam, sshd, login, and gdm ## Might also want to watch these files if needing extra information #-w /var/log/tallylog -p wa -k logins #-w /var/run/faillock/ -p wa -k logins #-w /var/log/lastlog -p wa -k logins ##- Process and session initiation (unsuccessful and successful) ## ## The session initiation is audited by pam without any rules needed. ## Might also want to watch this file if needing extra information #-w /var/run/utmp -p wa -k session #-w /var/log/btmp -p wa -k session #-w /var/log/wtmp -p wa -k session ##- Discretionary access control permission modification (unsuccessful ## and successful use of chown/chmod) -a always,exit -F arch=b32 -S chmod,fchmod,fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod -a always,exit -F arch=b64 -S chmod,fchmod,fchmodat -F auid>=1000 -F auid!=unset -F key=perm_mod -a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F auid>=1000 -F auid!=unset -F key=perm_mod -a always,exit -F arch=b64 -S chown,fchown,lchown,fchownat -F auid>=1000 -F auid!=unset -F key=perm_mod -a always,exit -F arch=b32 -S setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod -a always,exit -F arch=b64 -S setxattr,lsetxattr,fsetxattr,removexattr,lremovexattr,fremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod ##- Unauthorized access attempts to files (unsuccessful) -a always,exit -F arch=b32 -S open,creat,truncate,ftruncate,openat,open_by_handle_at -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access -a always,exit -F arch=b32 -S open,creat,truncate,ftruncate,openat,open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access -a always,exit -F arch=b64 -S open,truncate,ftruncate,creat,openat,open_by_handle_at -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access -a always,exit -F arch=b64 -S open,truncate,ftruncate,creat,openat,open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access ##- Use of print command (unsuccessful and successful) ##- Export to media (successful) ## You have to mount media before using it.
