The vCenter Server must enable data in transit encryption for vSAN.
Medium Severity
<VulnDiscussion>Transit encryption must be enabled to prevent unauthorized disclosure information and to protect the confidentiality of organizational information. vSAN data-in-transit encryption has the following characteristics: -vSAN uses AES-256 bit encryption on data in transit. -Forward secrecy is enforced for vSAN data-in-transit encryption. -Traffic between data hosts and witness hosts is encrypted. -File service data traffic between the VDFS proxy and VDFS server is encrypted. -vSAN file services inter-host connections are encrypted. -vSAN uses symmetric keys that are generated dynamically and shared between hosts. Hosts dynamically generate an encryption key when they establish a connection, and they use the key to encrypt all traffic between the hosts. You do not need a key management server to perform data-in-transit encryption. Each host is authenticated when it joins the cluster, ensuring connections only to trusted hosts are allowed. When a host is removed from the cluster, it is authentication certificate is removed. vSAN data-in-transit encryption is a cluster-wide setting. When enabled, all data and metadata traffic is encrypted as it transits across hosts.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
