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
