Security overview
Flex Appliance includes multiple features to ensure the security of your data. Each element of the appliance is tested for vulnerabilities using both industry standards and advanced security products. These measures ensure that exposure to unauthorized access and resulting data loss or theft is minimized.
Flex Appliance also uses the Security Technical Implementation Guide (STIG) template to meet security requirements per the Defense Information Systems Agency (DISA) profile. See the Flex Appliances with NetBackup Security white paper for more information.
The security features in this release include but are not limited to the following:
OS security hardening, including Security-Enhanced Linux (SELinux)
Forced password changes during initial configuration to make sure that the default password does not remain active on the system
The ability to set your own password policy, including the option to use STIG for validation
Lockdown mode and WORM storage support, which let you set additional access restrictions and block data deletion during a specified retention period
See About lockdown mode.
Session timeouts that automatically sign users out of the Flex Appliance Console and the Flex Appliance Shell after 10 minutes of inactivity
Additional password protection in the Flex Appliance Shell that locks the hostadmin account for 15 minutes after 3 incorrect login attempts
Password protection that restricts access to the GRUB menu except with assistance from Veritas Technical Support. If you need to edit GRUB, contact Technical Support and ask your representative to reference article 100048098.
Also note the following information regarding the appliance security:
IP forwarding is enabled in Flex Appliance by design; it is used to facilitate network communication between application instances and external networks.
