Ensure that all default passwords are changed as soon as the system is installed.
When creating user accounts, use role-based access control (RBAC) features to disable the ability to directly log in to common OS accounts such as root, grid, and oracle. Instead, create individual user accounts for each administrator. After logging in with their individual account, the administrator can use su to run privileged commands, when required.
Create and use Oracle ILOM user accounts for individual users to ensure a positive identification in audit trails.
Disable unnecessary protocols and modules in the OS.
Restrict the capability to restart the system over the network.
Limit SSH listener ports to the management and private networks.
Use SSH protocol 2 (SSH-2) and FIPS 140-2 approved ciphers.
Use intrusion prevention systems on servers to monitor network traffic flowing to and from Oracle SuperCluster T5-8.
Use host-based intrusion detection and prevention systems for increased visibility within Oracle SuperCluster T5-8. By using the fine-grained auditing capabilities of Oracle Database, host-based systems have a greater likelihood of detecting inappropriate actions and unauthorized activity.
Use application and network-layer firewalls to protect information flowing to and from Oracle SuperCluster T5-8. Filtering network ports provides the first line of defense in preventing unauthorized access to systems and services.
Network-level segmentation using Ethernet VLANs and host-based firewalls enforce inbound and outbound network policy at the host level. SuperCluster T5-8 includes a configured software firewall by default.
Use encryption features such as Transparent Data Encryption (TDE) and Oracle Recovery Manager (RMAN) encryption for backups.
Use centralized audit and log repositories to aggregate the security-relevant information for improved correlation, analysis, and reporting.
