AMI

Required Configuration Changes

CentOS 7 (x86_64) - with Updates HVM

This AMI does not include Java, but Tenable Security Center requires OpenJDK or the Oracle Java JRE to export PDF reports. You must install OpenJDK or the Oracle Java JRE onto your AMI before hosting Tenable Security Center. For more information, see Dependencies. This AMI configures an SELinux enforcing mode policy, which requires customization to be compatible with Tenable Security Center. You must use the SELinux sealert tool to identify errors and solutions. For more information, see Customize SELinux Enforcing Mode Policies for Tenable Security Center. You must confirm this AMI meets all other standard requirements for operating systems. For more information, see Operating System Requirements.
