The NFSv4.1 client can be enabled to be a direct participant in the exact location of file data and to avoid solitary interaction with one NFS server when moving data. In addition to pNFS, NFSv4.1 provides: Sessions; Directory Delegation and Notifications; Multi-server Namespace; access control lists and discretionary access control; Retention ...
Kerberized Internet Negotiation of Keys (KINK) is a protocol defined in RFC 4430 used to set up an IPsec security association (SA), similar to Internet Key Exchange (IKE), utilizing the Kerberos protocol to allow trusted third parties to handle authentication of peers and management of security policies in a centralized fashion.
While WebNFS itself did not gain much traction, several important WebNFS features later became part of NFSv4, including use of port 2049, and the concept of a fixed "root filehandle" (which evolved from WebNFS public filehandles and allows exported filesystems to be accessed without needing the MOUNT protocol to learn their individual root handles first); both together allow NFSv4 to function ...

a Kerberos realm name; an Active Directory domain name; the name of an operating-system vendor (for distribution-specific allocations) the name of a computer (for device-specific allocations) But in practice many existing implementations only allow setting the NFSv4 domain to a fixed value, thereby rendering it useless.

In computer security, an access-control list (ACL) is a list of permissions [a] associated with a system resource (object or facility). An ACL specifies which users or system processes are granted access to resources, as well as what operations are allowed on given resources. [ 1 ]
Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations.
