What is Microsoft NT LAN Manager in SAP BC-SEC - Security?

SAP Term: Microsoft NT LAN Manager

• Component: BC-SEC

• Component Name: Security

• Description: Windows NT authentication protocol that uses a challenge and response algorithm for authenticating users within a Windows NT network. The Microsoft NT LAN Manager sets up credentials for the user that are obtained during an interactive logon process. The credentials consist of a domain name, a user name, and a one-way hash of the user's password. Afterwards, the NTLM uses an encrypted challenge/response procedure to authenticate the user without transmitting the user's password. Instead, the system requesting authentication must perform a calculation that proves it has access to the secured NTLM credentials.

• Key Concepts: 
  Microsoft NT LAN Manager (NTLM) is a security protocol developed by Microsoft for authentication and authorization of users on a network. It is used in SAP systems to authenticate users and control access to resources. NTLM is based on the challenge-response authentication protocol, which requires the user to provide a valid username and password in order to gain access. 
  
  How to use it: 
  In order to use NTLM in an SAP system, the user must first be authenticated by the system. This is done by providing a valid username and password. Once authenticated, the user will be able to access resources that are protected by NTLM. 
  
  Tips & Tricks: 
  It is important to remember that NTLM is only used for authentication and authorization of users on a network. It does not provide any encryption or data protection. Therefore, it is important to use other security measures such as encryption and data protection when transmitting sensitive data over a network.
