about_Two_Factor_Authentication SHORT DESCRIPTION How to utilize two factor authentication with the HPE Oneview PowerShell library. LONG DESCRIPTION Passwords, no matter how complex, provide insufficient security for many applications. For additional security, use two-factor authentication. With two-factor authentication, two factors are required for HPE OneView authentication. The two factors are something the user possesses (a smart card), and something the user knows (a personal identification number). HPE OneView user/password authentication ---------------------------------------- Users can be configured in HPE OneView as local users, or remotely in an enterprise directory. The traditional user name and password login sequence is as follows: 1. The user types their user name and password. 2. HPE OneView authenticates the user name and password. * If the user name is that of a local user configured in HPE OneView, HPE OneView validates a manually specified user name and password using the HPE OneView database. * If your environment is configured to use an enterprise directory, HPE OneView immediately forwards the user name and password to a configured directory server for authentication. 3. Once authentication is successful, HPE OneView determines the authorization permissions for the user. * If it is a local user login, authorization permissions are decided based on the roles associated with the user. * If it is an enterprise directory login, HPE OneView sends a request to the directory server to retrieve the group name associated with the user. It uses the group name to determine the authorization permission for the user configured in HPE OneView. HPE OneView two-factor authentication ------------------------------------- Enabling two-factor authentication allows you to use smart cards — for example, Common Access Cards (CAC), or Personal Identity Verification (PIV) cards — to authenticate within HPE OneView. The client certificate embedded in the smart card is presented to HPE OneView by the library. The client certificate must be signed by a root or intermediate Certificate Authority (CA) that has been previously imported into HPE OneView. The appliance authenticates the client certificate to validate that the user name specified in the certificate is that of a valid user recognized by the directory server configuration in HPE OneView. When two-factor authentication is enabled, HPE OneView uses a Microsoft Active Directory service account set up and owned by the user to access an Active Directory entry for the user, rather than using an account associated with the user name received during first time login. The certificates stored on CAC/PIV cards are X.509 security certificates. They contain fields of information used to identify the certificate owner, the certificate issuer, and other certificate identification elements. When you enable two-factor authentication, you can specify which certificate fields HPE OneView must use to validate a user. An Infrastructure administrator also has the flexibility to customize the rules HPE OneView applies during client certificate authentication. The Infrastructure administrator can configure the locations within the certificate from which HPE OneView retrieves the user name, domain name and the OIDs that must be present for the certificate to be valid. See Set-OVApplianceTwoFactorAuthentication help. AUTHENTICATING USING A SMARTCARD The users smart card or digital badge must be present on the PC. Using PowrShell's native Certificate provider, the smart card can be accessed using the following: PS C:\> $MyCertificate = gci Cert:\CurrentUser\my | ? { $_.EnhancedKeyUsageList.FriendlyName -match 'Smart Card Logon' } Then, the $MyCertificate object can be passed into the Connect-OVMgmt Cmdlet: PS C:\> Connect-OVMgmt -Hostname Myappliance.domain.com -Certificate $MyCertificate GLBOAL CONNECTION TRACKING OBJECT AND 2FA PROPERTIES Contained in the $ConnectedSessions Global varilable, will be each successful appliance connection object, HPEOneView.Appliance.Connection. When authenticating with a smart card, the AuthType property of the HPEOneView.Appliance.Connection object will be set to "Certificate". The "Authentication" property will be set to the Active Directory authentication directory that authenticated the request. The "ActivePermissions" property will contain the available Scopes and Roles. To examine which Roles and Scopes are available for the logged in account, examine the [HPEOneView.Appliance.Connect].ActivePermissions property. This property is a collection of HPEOneView.Appliance.ActivePermissions objects. The [String]ScopeName, [String]RoleName, and [Bool]Active properties The SessionID within HPEOneView.Appliance.Connection object contains the current users active permission set. To modify the active permission set, use either the Pop-OVAppliancePermission or Push-OVAppliancePermission Cmdlets. HOW TO USE SCOPES IN CMDLETS Scopes by default are managed by Infrastructure administrators, unless the HPEOneView.Appliance.ScopeCollection resource has been scoped to a local user or directory user with Scope administrator role. Once a scope has been created, it can be used to filter for supported resource objets: * Enclosures * Server Hardware * Networks (Ethernet, FC, and FCoE) * Network Sets * Interconnects, excluding SAS resources * Logical Interconnects, excluding SAS resources * Logical Interconnect Groups, excluding SAS resources * Switches * Logical Switches * Logical Switch Groups The supporting Cmdlets for the above resources include a -Scope parameter that allowed the caller to supply one or more HPEOneView.Appliance.ScopeCollection resources to filter. By default, the appliance will return all available resources that are part of the users Active Permissions Set. For instance, Get-OVNetwork -Scope $MyScopeObject will return only the network objects that are a member of the scope within the $MyScopeObject variable: PS C:\> $MyScopeObject = Get-OVScope -Name MyScope -ErrorAction Stop PS C:\> Get-OVNetwork -Scope $MyScopeObject Type: Ethernet Name Status Purpose Type VlanID IPv4Subnet Smartlink PrivateNetwork PreferredBandwidth MaxBandwidth ---- ------ ------- ---- ------ ---------- --------- -------------- ------------------ ------------ Dev VLAN 101-A OK General Tagged 101 None True False 2500 20000 Dev VLAN 101-B OK General Tagged 101 None True False 2500 20000 Dev VLAN 102-A OK General Tagged 102 None True False 2500 20000 Dev VLAN 102-B OK General Tagged 102 None True False 2500 20000 Dev VLAN 103-A OK General Tagged 103 None True False 2500 20000 Dev VLAN 103-B OK General Tagged 103 None True False 2500 20000 Dev VLAN 104-A OK General Tagged 104 None True False 2500 20000 Dev VLAN 104-B OK General Tagged 104 None True False 2500 20000 Dev VLAN 105-A OK General Tagged 105 None True False 2500 20000 Dev VLAN 105-B OK General Tagged 105 None True False 2500 20000 Type: Fibre Channel Name Status Type TypicalBandwidth MaxBandwidth AutoLoginRedistribution LinkStabilityInterval ManagedSAN ---- ------ ---- ---------------- ------------ ----------------------- --------------------- ---------- Fabric A OK FabricAttach 4000 20000 True 30 SA Fabric B OK FabricAttach 4000 20000 True 30 SA ...
