Description
  • Windows Server 2003 was the follow-up to Windows
    2000 Server, incorporating compatibility and
    other features from Windows XP. Unlike Windows
    2000 Server, Windows Server 2003's default
    installation has none of the server components
    enabled, to reduce the attack surface of new
    machines. Windows Server 2003 includes
    compatibility modes to allow older applications
    to run with greater stability. It was made more
    compatible with Windows NT 4.0 domain-based
    networking. Incorporating and upgrading a Windows
    NT 4.0 domain to Windows 2000 was considered
    difficult and time-consuming, and generally was
    considered an all-or-nothing upgrade,
    particularly when dealing with Active
    Directory.by whom? Windows Server 2003 brought
    in enhanced Active Directory compatibility, and
    better deployment support, to ease the transition
    from Windows NT 4.0 to Windows Server 2003
    and Windows XP Professional.

  • Networked NT machines can be
  • Primary Domain controller
  • Centralizes user database/authentication
  • Backup Domain controller
  • Domain member
  • Non-domain member
  • Trusted domains
  • Trusting resources
  • Security viewpoint
  • Four main components
  • Executive (kernel mode)
  • Protected Servers (user mode)
  • Network Subsystem (both kernel and user modes)
  • Administrator tools (user mode)

Handle tables
  • Each process has a table of object handles
    which enable the process to access those
    resources
  • Maintained by object manager
  • Each handle describes the type of access the
    process has to the object (read, write, etc)
  • The object manager ensures that access is only
    granted if compatible with the handle
  • When a process requests a new resource for the
    first time, the Object Manager asks the Security
    Reference Monitor to decide if the process may
    acquire the handle.

Security-related servers
  • Winlogon
  • Session Manager
  • Local Security Authority
  • Security Accounts Manager (SAM)
  • Service Controller
  • Event Logger
  • Local Security Authority Subsystem Service
    (LSASS)
  • Invoked at login time, it verifies the user
    authentication and grants the system access token
    (SAT), which is used to start the initial shell
    and is inherited by all programs spawned during
    this login session
  • Performs audit functions
  • Operates in user mode
