cwesMills and jdekonin Fixed bugs in ANT windows role
The ant url was changed but forgot to update 1.10.3 to 1.10.5 when
testing if ant was already installed. Also added /m when declaring
ANT_HOME so the variable will be set at the system level.

**Proposed Schedule**

Scheduled Date Eastern Time Zone British Time Zone
July 21, 2017 3pm - 5pm - Daylight Time (UTC - 4) 20:00 - 22:00 - Summer Time (UTC + 1)

Standard Action Items:

  • Apply non-security patches to infrastructure systems.
  • Apply Application patches to: Nagios, Jenkins, AWX, etc.


The following items are stored in GitHub.

  • Source code, System deployment scripts (Ansible), Instructions/How to Information
Description Storage Location Frequency
Jenkins (ci) - Configuration and Settings localhost /mnt/backup-server/jenkins_backup Daily
Jenkins (ci-jck) - Configuration and Settings localhost /mnt/backup/ Daily
Nagios - Configuration and Settings localhost /root/backups Weekly
AWX - Configuration and Settings not currently backed up N/A

Backup schedule:

  • How often should be backup?
  • Where should it be stored?

Backup retention:

  • How long should be keep it?
  • How many copies?

OS Patch Management:

Most of our systems are internet facing and we need to stay vigilant of the potential security risks this presents.

Patch Management Time Frame:
Vulnerability Type Time Frame
Critical severity 72 hours or less
High severity 7 days
Moderate and low severity 60 days
  • Nagios is configured to monitor each system and report on the status of OS patches required.
  • Non-infrastructure systems are configured to automatically apply all patches. (Sundays at 5am local host time)
  • Infrastructure systems are configured to automatically apply security patches only. (Sundays at 5am local host time) This information is logged on the localhost: /var/log/apt-security-updates

Application Updates:

  • During our quarterly maintenance window application patches will be applied manually.
  • When a critical or high severity vulnerability is announced patching will take place within the time frame stated above.
