VMware vSphere 8.0 ESXi Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The ESXi host must set a timeout to automatically end idle shell sessions after fifteen minutes.
If a user forgets to log out of their local or remote ESXi Shell session, the idle connection will remain open indefinitely and increase the likelihood of inappropriate host access via session hija...Rule Medium Severity -

The ESXi host must enable Secure Boot.
Secure Boot is part of the Unified Extensible Firmware Interface (UEFI) firmware standard. With UEFI Secure Boot enabled, a host refuses to load any UEFI driver or app unless the operating system b...Rule Medium Severity -

Group -
The ESXi host must enforce an unlock timeout of 15 minutes after a user account is locked out.
By enforcing a reasonable unlock timeout after multiple failed logon attempts, the risk of unauthorized access via user password guessing, otherwise known as brute forcing, is reduced. Users must w...Rule Medium Severity -

Group -
The ESXi host must allocate audit record storage capacity to store at least one week's worth of audit records.
In order to ensure ESXi has sufficient storage capacity in which to write the audit logs, audit record storage capacity should be configured. If a central audit record storage facility is availab...Rule Medium Severity -

Group -
The ESXi host must offload logs via syslog.
Remote logging to a central log host provides a secure, centralized store for ESXi logs. By gathering host log files onto a central host, it can more easily monitor all hosts with a single tool. It...Rule Medium Severity -

The ESXi Image Profile and vSphere Installation Bundle (VIB) acceptance level must be verified.
Verify the ESXi Image Profile to only allow signed VIBs. An unsigned VIB represents untested code installed on an ESXi host. The ESXi Image profile supports four acceptance levels: 1. VMwareCertif...Rule High Severity -

Group -
The ESXi host must enable bidirectional Challenge-Handshake Authentication Protocol (CHAP) authentication for Internet Small Computer Systems Interface (iSCSI) traffic.
When enabled, vSphere performs bidirectional authentication of both the iSCSI target and host. When not authenticating both the iSCSI target and host, there is potential for a man-in-the-middle att...Rule Medium Severity -

The ESXi host Secure Shell (SSH) daemon must be configured to only use FIPS 140-2 validated ciphers.
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. ESXi must implement cryptographic modules adhering to the higher standards approved by...Rule Medium Severity -
