    Study Notes

    Security Mechanisms

    • Multi-factor authentication (MFA) enhances security by requiring multiple verification factors (e.g., password, SMS code, biometrics).
    • Public key infrastructure (PKI) utilizes digital certificates and private keys for secure communications between entities.
    • OAuth enables third-party applications to access user resources without sharing sensitive credentials.
    • Windows Authentication (NTLM) is specific to Windows environments, using domain accounts and challenge-response methods, moving towards Kerberos models.

    User Accounts

    • User accounts are profiles determining network access, existing in the Security Accounts Manager (SAM) or Domain Controller (DC).
    • Account types include:
      • Local accounts: limited to workgroup access, authenticated by SAM.
      • Domain accounts: access network resources, authenticated by DC and listed in Active Directory (AD).
      • Built-in accounts: automatically generated by OS or AD, including:
        • Standard accounts: typical user access.
        • Administrator accounts: full system access, varying by network scope.
        • Guest accounts: limited, temporary access without network permissions.

    User/Group Management

    • Involves creating, modifying, and deleting user accounts and groups to manage permissions and access.
    • Management tools include:
      • GUI: Control Panel for easy management.
      • Command Line Interface (CLI): commands like ‘net user’ and ‘net localgroup’ to manipulate user accounts and groups.
      • PowerShell: commands such as ‘New-LocalUser’ for user creation and ‘New-LocalGroup’ for group management.

    Windows Command Line

    • Known as cmd.exe, it provides a text-based interface to execute commands.
    • Basic command functions include:
      • dir: Lists directory contents.
      • cd: Changes directories.
      • copy: Copies files between locations.
      • move: Moves files.
      • del: Deletes files.
      • mkdir: Creates a new directory.
      • ipconfig: Displays network configuration details.
      • exit: Closes Command Prompt.

    Windows Boot Process

    • The booting sequence involves loading system firmware and the operating system:
      • WinLoad.exe initiates core drivers necessary for the Windows Kernel.
      • The kernel initializes hardware and reads registry settings.
    • User Mode Startup leads to processes like:
      • Starting subsystem processes (smss.exe) and services (services.exe), culminating in the display of the Windows login screen.

    Kernel Designs

    • The kernel acts as a mediator between hardware (Hardware Abstraction Layer - HAL) and system resources, critical for process management.
    • Driver software enables communication between devices and the operating system, acting as translators.
    • Kernel designs can be monolithic (single large block of code) or microkernel (smaller, more modular components).

    File Systems and Permissions

    • The file system organizes how data is named, stored, and accessed.
    • Windows uses Discretionary Access Control Lists (DACL) for file permissions, determining user access levels post-authentication.

    Concurrency and Interrupts

    • Concurrency allows a system to manage multiple tasks simultaneously, optimizing CPU resource utilization.
    • Interrupts are events occurring out of the normal program execution, often due to errors that signal the OS to take action.

    PowerShell Commands (PS Demonstration)

    • Commands include:
      • Get-Help: Displays help for cmdlets.
      • Get-Process: Retrieves running processes.
      • New-Item: Creates new files or directories.
      • Copy-Item: Copies items between locations.
      • Remove-Item: Deletes specified files or directories.
