The software described in this documentation is either in Extended Support or Sustaining Support. See https://www.oracle.com/us/support/library/enterprise-linux-support-policies-069172.pdf for more information.
Oracle recommends that you upgrade the software described by this documentation as soon as possible.
When you install Oracle Linux, you can reduce the attack surface
by installing only the software packages that are required for
operation. Software packages are a potential source of
setuid programs, network services, and
libraries that an attacker can potentially use to gain access
illegitimately and compromise a system.
You can use a pretested kickstart profile to provide consistent and precise control over what is installed. Automated installation using a kickstart profile reduces both security risk and administrative effort.
Alternatively, you can use Oracle Enterprise Manager Ops Center, which supports the import of OS images and explicit provisioning profiles. For more information, refer to the Oracle Enterprise Manager Ops Center documentation.
