Simple Object Access Protocol (SOAP) Messaging protocol specification for exchanging structured information in the implementation of web services in computer networks. Allows developers to invoke processes running on disparate operating systems (such as Windows, macOS, and Linux) to authenticate, authorize, and communicate using Extensible Markup Language (XML). Since Web protocols like HTTP are installed and running on all operating systems, SOAP allows clients to invoke web services and receive responses independent of language and platforms.   Wikipedia

data integrity (checksum) Maintenance of, and the assurance of the accuracy and consistency of data over its entire life-cycle, and is a critical aspect to the design, implementation and usage of any system which stores, processes, or retrieves data. The term is broad in scope and may have widely different meanings depending on the specific context – even under the same general umbrella of computing.   Wikipedia         

entity integrity Concerned with ensuring that each row of a table has a unique and non-null primary key value; this is the same as saying that each row in a table represents a single instance of the entity type modelled by the table. A requirement of E. F. Codd in his seminal paper is that a primary key of an entity, or any part of it, can never take a null value.   Wikipedia

Internet Key Exchange (IKE) (UDP port 500, RFC 2409) Used to set up a security association (SA) in the IPsec protocol suite to authenticate users and devices. Builds on the Oakley protocol and ISAKMP. Uses X.509 certificates for authentication. Several types of authentication: username, password, one-time password, biometrics, PSK, and digital certificates. Originally defined by the IETF in RFC 2407, RFC 2408 and RFC 2409 November 1998.  Wikipedia  RFC 2407  RFC 2408  RFC 2409

Internet Protocol Security (IPsec) Framework of open standards defining how a VPN can be configured and secured. Provides data integrity, peer authentication, data confidentiality (encryption). Not bound to any encryption, authentication, security algorithms, or keying technology. Uses Authentication Headers (AH), Encapsulating Security Payloads (ESP), and Security Associations (SA) as part of its security architecture. The Cisco IPsec implementation uses DES and 3DES in Cipher Block Chaining (CBC) mode. Works at the network layer (Layer 3) encapsulating IP packets. Uses a plaintext Layer 3 header to allow for routing compatibility. When configuring, a few basic parts must be provided: IPsec protocol, confidentiality, integrity, authentication, and secure key exchange.   Wikipedia

Virtual Private Network (VPN) IP tunnels that extend a private network across a public network, usually the internet. Enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Typically encrypted but does not need to be, such as in the case of GRE and Frame Relay. The encryption algorithm combines message text with a key to make the message unreadable by unauthorized receivers. Two kinds of VPNs: site-to-site and remote access. Can operate at OSI Layer 2 (Frame Relay, ATM, HDLC, PPP) or OSI Layer 3 (GRE, MPLS, IPsec).   Wikipedia

NT LAN Manager (NTLM) Suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. The NTLM protocol suite is implemented in a Security Support Provider, which combines the LAN Manager authentication protocol, NTLMv1, NTLMv2 and NTLM2 Session protocols in a single package. Whether these protocols are used or can be used on a system is governed by Group Policy settings, for which different versions of Windows have different default settings. NTLM passwords are considered weak because they can be brute-forced very easily with modern hardware. Successor to the authentication protocol in Microsoft LAN Manager (LANMAN).  Wikipedia
