Elastic Stack 6 : Install Auditbeat
2018/02/12
 
Install Auditbeat that can monitor Audit actions.
[1] Install Auditbeat. Configure Elasticsearch repository before it.
[root@dlp ~]#
yum -y install auditbeat
[2] Configure basic settings and start Auditbeat.
[root@dlp ~]#
vi /etc/auditbeat/auditbeat.yml

- module: auditd
  audit_rules: |
    ## Define audit rules here.
    ## Create file watches (-w) or syscall audits (-a or -A). Uncomment these
    ## examples or add your own rules.

    ## If you are on a 64 bit platform, everything should be running
    ## in 64 bit mode. This rule will detect any use of the 32 bit syscalls
    ## because this might be a sign of someone exploiting a hole in the 32
    ## bit API.
    #-a always,exit -F arch=b32 -S all -F key=32bit-abi

    ## Executions.
    #-a always,exit -F arch=b64 -S execve,execveat -k exec

    ## External access (warning: these can be expensive to audit).
    #-a always,exit -F arch=b64 -S accept,bind,connect -F key=external-access

    ## Identity changes.
    #-w /etc/group -p wa -k identity
    #-w /etc/passwd -p wa -k identity
    #-w /etc/gshadow -p wa -k identity

# line 88: if use Kibana, uncomment and specify output host
