Hi guys,
Can someone tell me how i can create rules based in the auditd decoders
that i had wrote?
My decoders:
<decoder name="auditd">
<prematch>^type=</prematch>
</decoder>
<decoder name="auditd-syscall">
<parent>auditd</parent>
<prematch offset="after_parent">^SYSCALL </prematch>
<regex offset="after_parent">^(SYSCALL)
msg=audit\(\d\d\d\d\d\d\d\d\d\d.\d\d\d:(\d+)\):\s+arch=\w+\s+syscall=\d+\s+success=(\S+)\s+exit=\S+\s+a0=\w+\s+a1=\w+\s+a2=\w+\s+a3=\w+\s+items=\d+\s+ppid=\d+\s+pid=\d+\s+auid=\d+\s+uid=\d+\s+gid=\d+\s+euid=\d+\s+suid=\d+\s+fsuid=\d+\s+egid=\d+\s+sgid=\d+\s+fsgid=\d+\s+tty=\S+\s+ses=\d+\s+comm="\S+"\s+exe="(\S+)"\s+key="(\w+)"</regex>
<order>system_name,id,status,action,extra_data</order>
</decoder>
<decoder name="auditd-cwd">
<parent>auditd</parent>
<prematch offset="after_parent">^CWD </prematch>
<regex offset="after_parent">^(CWD)
msg=audit\(\d\d\d\d\d\d\d\d\d\d.\d\d\d:(\d+)\):\s+cwd="(\.+)"</regex>
<order>system_name,id,extra_data</order>
</decoder>
<decoder name="auditd-path">
<parent>auditd</parent>
<prematch offset="after_parent">^PATH </prematch>
<regex offset="after_parent">^(PATH)
msg=audit\(\d\d\d\d\d\d\d\d\d\d.\d\d\d:(\d+)\):\s+item=\d+\s+name="(\.+)"\s+inode=\d+\s+dev=\S+\s+mode=\d+\s+ouid=\d+\s+ogid=\d+\s+rdev=\S+</regex>
<order>action,id,extra_data</order>
</decoder>
The multi-log feature in ossec 2.7 for auditd dont work?
Im having problems to correlate rules.
Sorry for my bad english.
Regards,
