Many security layers Keep in mind that when it comes to securing a network, there are many security layers and many different types of security that may be enforced.

Active Directory Active Directory (AD) is a component of Microsoft Server AD technology is based on standard Internet protocols. Uses the Domain Name System (DNS). DNS is a standard Internet service that organizes groups of computers into domains.

Active Directory Provides centralized authentication and authorization services for Windows based computers. Allows administrators to assign policies, deploy software, and apply updates to an entire network.

Active Directory

Microsoft Server 2003 File Server Print Server Application Server Domain Controller Mail Server Terminal Server VPN Server DHCP Server Server 2003 can be used as a server for a number of different things. Along with the examples we mentioned in class, a server can also be used for the above tasks. A server can do many things, they are not limited to the items on this screen.

Windows Networking without a Server Managing a network without a Domain Controller can be difficult. Keeping the network secure is even more difficult. Usually a peer-to-peer network. Vulnerable to viruses and being hacked.

Windows Networking without a Server Keep your computer up to date by running Windows Updates. –Security Patches

Windows Networking without a Server Use Anti-Virus software to protect against Trojans, Worms, and other malicious software.

Windows Networking without a Server Enable Windows Firewall Only allow exceptions for the services that are absolutely necessary for the network.

Windows Networking without a Server The use of user accounts will help protect hackers from gaining access to your peer-to-peer network. Strong passwords Non-administrator account

Windows Networking without a Server Automatic Updates Virus Protection Firewall Users accounts Disable Windows Services

Windows Networking with a Server Allows better control of user accounts and user groups. (AD) Allows updates to be forced to computers. (AD) More secure and organized file/print sharing. Allows strong security policies. Policies can be forced to computers.

Windows Networking with a Server User Accounts Enables better security and better user account control. Roaming Profiles Remote Access Dial-in Access Logon Hours Ability to disable accounts Groups

Windows Networking with a Server File Permissions Server 2003 allows an administrator to assign file permissions to files, folders, and printers shared across the network. Permissions can be set for a specific user, or a group of users. NTFS permissions can be set with a Graphical User Interface or the command line.

Windows Networking with a Server File Permissions Share PermissionsNTFS Permissions

Windows Networking with a Server Password Policy Server 2003 allows an administrator to set a password policy for all users to abide by. Password History Password Age Password Length Complexity Requirements

Windows Networking with a Server Password Policy

Windows Networking with a Server Account Lockout Policy Server 2003 allows an administrator to set an account lockout policy.

Windows Networking with a Server Group Policy Allows an administrator to enforce various policies to the entire network, domain or specific Organization Unit (OU).

Windows Networking with a Server Group Policy: Security Policy Restrict access to the CD-ROM and Floppy Drive Disconnect users when logon hours expire Let “everyone” permissions apply to anonymous Access the registry remotely Access shares anonymously

Windows Networking with a Server Group Policy: Administrative Templates Remove icons from the desktop (i.e. My Computer, Network Places, etc.) Allow/Deny access to the Control Panel Restrict display settings (i.e. force background, no screensaver) Remove items from the Ctrl + Alt + Del menu (i.e. Task Manager, Lock Computer, Change Password)
