This policy setting determines if RPC clients authenticate with the Endpoint Mapper Service when their call includes authentication data. The Endpoint Mapper Service on Windows NT4 (all service packs) is unable to process authentication data provided in this manner. Disabling this policy means RPC clients won’t authenticate with the Endpoint Mapper Service, but they can still communicate with it on Windows NT4 Server. The recommended state for this setting is: Enabled.

The software supply chain is increasingly complex, giving threat actors more opportunities to find ways into your system, either via custom code or third-party code. In this blog we’ll briefly go over five supply chain threats and where to find them. For a deeper look to finding these threats, with more specifics and tool suggestions, check out our threat hunting guide.

Orphaned users SQL Server arise when a database user is associated with a login in the master database that no longer exists and should be removed. This situation can happen when the login is removed or when the database is transferred to a different server lacking the corresponding login. The SQL Server logins existing on a server instance can be seen through the sys.server_principals catalog view and the sys.sql_logins compatibility view.

To answer this question, let’s first look at some history. Processes are software instances running in their own memory spaces. They enable a user to execute multiple software instances in parallel on the same computer. The concepts are derived from operating systems of the 1960s, with UNIX first being released in 1971. In today’s operating systems, every process is associated with an identity to which authorizations are bound. This enables the definition of access controls around processes.

Windows permits an anonymous user to carry out specific actions, such as listing the names of domain accounts and network shares. This functionality proves useful in scenarios when an administrator needs to provide access to users in a trusted domain lacking a reciprocal trust agreement. By default, the Everyone security identifier(SID) is excluded from the token generated for anonymous connections. Consequently, permissions assigned to the Everyone group don’t extend to anonymous users.
