    Study Notes

    Windows Versions Overview

    • MS-DOS, created in 1981, operates strictly via command line.
    • Early exploits included IIS malware, buffer overflow attacks, DNS exploits, and Denial of Service (DoS) attacks.
    • Windows 95, architecture version 3.1, introduced auto-run for disks and USBs.
    • Windows 98, architecture version 4.1, featured FAT32 and Active Desktop with an integrated web browser.
    • Windows 2000, architecture version 5.0, brought in Active Directory and Azure AD for cloud-based management.
    • Windows XP, architecture version 5.1, implemented Windows Firewall, Data Execution Prevention (DEP), and NTFS, first supported in Windows NT 3.1.
    • Windows Vista, architecture version 6.0, introduced User Access Control (UAC), BitLocker Drive Encryption, Windows Defender, and session management.
    • Windows 7, architecture version 6.1, added multi-touch support, Internet Explorer 8, and improved boot performance with Virtual Hard Disk support.
    • Windows 10 and 11 support architectures x86-64 (64-bit) and ARM64 for selected editions; features include Microsoft Defender Anti-Virus, Windows Update, and Secure Boot.

    User Accounts Types

    • User accounts define profiles for network access, existing in either the Security Account Manager (SAM) or Domain Controller (DC).
    • Local accounts are specific to a single computer, do not grant network resource access, and are authenticated by SAM.
    • Domain accounts are managed by Active Directory, providing access to resources across multiple computers within a domain.
    • Built-in accounts, standard (everyday use), administrator (full system access), and guest accounts (temporary access with limitations), can exist locally or in domains.

    Local vs. Domain Accounts

    • Local Account:

      • Authentication happens on the local computer.
      • Limited access, only usable on the machine where created.
      • Managed locally; suitable for home or small networks.
      • Advantages include simplicity and independence from the network.
      • Disadvantages highlight limited access to a single computer.

    • Domain Account:

      • Authentication is via the domain controller.
      • Allows network-wide access to resources.
      • Centrally managed through Active Directory, ideal for large organizations.
      • Advantages include centralized control and Single Sign-On (SSO).
      • Requires domain infrastructure, adding complexity.

    Service Accounts

    • Designed for running applications, services, or system processes without user interaction.
    • Types of built-in service accounts:
      • LocalSystem: Privileged account with full system control; essential for core services.
      • LocalService: Limited-privileged account, operating local services; no password required.
      • NetworkService: More privileges than LocalService; intended for services needing network access.

    Security Identifiers (SID)

    • Unique identifiers assigned to each user, group, or computer account in the OS, controlling access to files, directories, and registry keys.
    • General format: S-1-5-21-3623811015-3361044348-30300820-1013.
    • Components of a SID:
      • Initial 'S' indicates it’s a SID.
      • Revision level (currently 1) and authority identifier (usually 5) specify security authority.
    • User SID assigned to individual user accounts, Group SID for group accounts, Computer SID for machines within domains, and Well-Known SIDs for generic accounts (e.g., Local System, Local Service, Network Service).

    Functions and Usage of SIDs

    • Used in Access Control Lists (ACLs) to define permissions for users and groups.
    • Facilitates authentication and authorization during user logon through SID verification.
    • Ensures unique identification of users and computers, even if names are duplicated.

    Access Tokens

    • Access tokens are data structures containing security information about logged-in users or processes.
    • They include user identity, group memberships, and privileges.
    • Control access to resources and enforce security policies.
    • Created during user logon:
      • User enters credentials, authenticated against SAM or AD.
      • Upon successful authentication, a token is generated and assigned to the logon session.
