The ESXi host SSH daemon must not permit user environment settings.
Activities performed from the ESXi Shell bypass vCenter RBAC and audit controls. The ESXi Shell is an interactive command line environment available locally from the DCUI or remotely via SSH.
The ESXi host must disable ESXi Shell unless needed for diagnostics or troubleshooting. When this is done, only a single day's worth of. This occurs when the host's "/scratch" directory is linked to "/tmp/scratch". The ESXi host must enable a persistent log location for all locally stored logs.ĮSXi can be configured to store log files on an in-memory file system. This feature can increase the attack surface of an SSH connection. X11 forwarding over SSH allows for the secure remote execution of X11-based applications. The ESXi host SSH daemon must be configured to not allow X11 forwarding. This is done to ensure the roles and access controls implemented in.

If compression is allowed in an SSH connection prior to authentication, vulnerabilities in the compression software could result in compromise of the system from an unauthenticated connection.Īccess to the ESXi host must be limited by enabling Lockdown Mode.Įnabling Lockdown Mode disables direct access to an ESXi host, requiring the host to be managed remotely from vCenter Server. The ESXi host SSH daemon must not allow compression or must only allow compression after successful authentication. By gathering host log files onto a central host, it can more easily monitor all hosts with a single tool. Remote logging to a central log host provides a secure, centralized store for ESXi logs. The ESXi host must centrally review and analyze audit records from multiple components within the system by configuring remote logging. Installing software updates is a fundamental mitigation against the exploitation of publicly known vulnerabilities. The ESXi host must have all security patches and updates installed.

The SA must verify the integrity of the installation media before installing ESXi.Īlways check the SHA1 or MD5 hash after downloading an ISO, offline bundle, or patch to ensure integrity and authenticity of the downloaded files. The ESXi Image profile supports four acceptance levels:

An unsigned VIB represents untested code installed on an ESXi host. Verify the ESXi Image Profile to only allow signed VIBs. The ESXi Image Profile and vSphere Installation Bundle (VIB) Acceptance Levels must be verified. TLS 1.2 should be enabled on all interfaces and SSLv3, TL 1.1, and 1.0 disabled where supported. TLS 1.0 and 1.1 are deprecated protocols with well-published shortcomings and vulnerabilities. The ESXi host must exclusively enable TLS 1.2 for all endpoints. This allows it to stage malicious attacks on the devices in. If the virtual machine operating system changes the MAC address, it can send frames with an impersonated source MAC address at any time. The virtual switch MAC Address Change policy must be set to reject on the ESXi host. The ESXi host SSH daemon must not allow authentication using an empty password.Ĭonfiguring this setting for the SSH daemon provides additional assurance that remote logon via SSH will require a password, even in the event of misconfiguration elsewhere. Our research team installed the Virtual Machines and performed experiments, trying to identify patterns on how their network interfaces receive MAC addresses.Findings (MAC I - Mission Critical Public) Finding ID.We constantly scan the Internet for such information.This information comes from the two sources:
