+title: 'Record Unauthorized Creation Attempts to Files (unsuccessful) - open O_CREAT'
+
+
+description: |-
+ The audit system should collect unauthorized file accesses for
+ all users and root. The <tt>open</tt> syscall can be used to create new files
+ when O_CREAT flag is specified.
+ The following auidt rules will asure that unsuccessful attempts to create a
+ file via <tt>open</tt> syscall are collected.
+ If the <tt>auditd</tt> daemon is configured to use the <tt>augenrules</tt>
+ program to read audit rules during daemon startup (the default), add the
+ rules below to a file with suffix <tt>.rules</tt> in the directory
+ <tt>/etc/audit/rules.d</tt>.
+ If the <tt>auditd</tt> daemon is configured to use the <tt>auditctl</tt>
+ utility to read audit rules during daemon startup, add the rules below to
+ <tt>/etc/audit/audit.rules</tt> file.
+ <pre>
+ -a always,exit -F arch=b32 -S open -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
+ -a always,exit -F arch=b32 -S open -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
+ </pre>
+ If the system is 64 bit then also add the following lines:
+ <pre>
+ -a always,exit -F arch=b64 -S open -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
+ -a always,exit -F arch=b64 -S open -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
+ </pre>
+
+rationale: |-
+ Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
+ these events could serve as evidence of potential system compromise.

+title: 'Record Unauthorized Modification Attempts to Files (unsuccessful) - open O_TRUNC'
+
+description: |-
+ The audit system should collect detailed unauthorized file accesses for
+ all users and root. The <tt>open</tt> syscall can be used to modify files
+ if called for write operation of with O_TRUNC flag.
+ The following auidt rules will asure that unsuccessful attempts to modify a
+ file via <tt>open</tt> syscall are collected.
+ If the <tt>auditd</tt> daemon is configured to use the <tt>augenrules</tt>
+ program to read audit rules during daemon startup (the default), add the
+ rules below to a file with suffix <tt>.rules</tt> in the directory
+ <tt>/etc/audit/rules.d</tt>.
+ If the <tt>auditd</tt> daemon is configured to use the <tt>auditctl</tt>
+ utility to read audit rules during daemon startup, add the rules below to
+ <tt>/etc/audit/audit.rules</tt> file.
+ <pre>
+ -a always,exit -F arch=b32 -S open -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
+ -a always,exit -F arch=b32 -S open -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
+ </pre>
+ If the system is 64 bit then also add the following lines:
+ <pre>
+ -a always,exit -F arch=b64 -S open -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification

+ Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
+ these events could serve as evidence of potential system compromise.

+
+description: |-
+ The audit system should collect detailed unauthorized file
+ accesses for all users and root.
+ To correctly identify unsuccessful creation, unsuccessful modification and unsuccessful access
+ of files via <tt>open</tt> syscall the audit rules collecting these events need to be in certain order.
+ The more specific rules need to come before the less specific rules. The reason for that is that more
+ specific rules cover a subset of events covered in the less specific rules, thus, they need to come
+ before to not be overshadowed by less specific rules, which match a bigger set of events.
+ Make sure that rules for unsuccessful calls of <tt>open</tt> syscall are in the order shown below.
+ If the <tt>auditd</tt> daemon is configured to use the <tt>augenrules</tt>
+ program to read audit rules during daemon startup (the default), check the order of
+ rules below in a file with suffix <tt>.rules</tt> in the directory
+ <tt>/etc/audit/rules.d</tt>.
+ If the <tt>auditd</tt> daemon is configured to use the <tt>auditctl</tt>
+ utility to read audit rules during daemon startup, check the order of rules below in
+ <tt>/etc/audit/audit.rules</tt> file.
