Windows SAM (Windows Security Accounts Manager)

• Definition: The Security Accounts Manager (SAM) is a database in Microsoft Windows that stores user account information, including passwords.
• Function: Provides authentication and authorization services for user accounts on Windows systems.
• Components:

   * '''SAM Database''': A registry hive file that stores user credentials and account information.
   * '''SAM Service''': A Windows service responsible for managing and accessing the SAM database.
   * '''Registry Hive''': Stored as a file typically located in `C:\Windows\System32\config\SAM`.

• Features:

   * '''Password Storage''': Stores hashed versions of user passwords.
   * '''User Account Management''': Maintains information about user accounts, groups, and associated security identifiers (SIDs).
   * '''Authentication''': Works with the Local Security Authority (LSA) to authenticate users during login.
   * '''Access Control''': Implements policies for password complexity, expiration, and lockout.

• Usage: Critical for the authentication and management of local user accounts on Windows systems.

• Viewing user accounts stored in the SAM database:

   * Use the `net user` command to list user accounts:
     ```cmd
     net user
     ```

• Resetting a user password using the SAM service:

   * Open a command prompt with administrative privileges.
   * Use the `net user` command to reset the password:
     ```cmd
     net user username newpassword
     ```

• Configuring password policies through the SAM database:

   * Open the Local Security Policy editor (`secpol.msc`).
   * Navigate to `Account Policies` > `Password Policy` to set policies such as minimum password length, complexity requirements, and expiration.

• SAM Database file location:

   * The SAM database file is typically located in `C:\Windows\System32\config\SAM`.

• SAM (Security Accounts Manager): A critical component of Windows operating systems that stores user account information and passwords, providing authentication and authorization services, and implementing access control policies.
