Protecting DNS servers - Part 4
[James Michael Stewart]
Last week's tip covered how to delegate DNS administration
and how to use secured routing. This week's tip will review the next two DNS security improvements: delegating DNS administration and using secured routing.
Why protect DNS?
[James Michael Stewart]
Active Directory depends upon DNS. If DNS fails, so does Active Directory. This, in turn, means that if DNS fails, your entire network may be disabled. So what will happen to AD if DNS fails? Find out in this tip.
White Paper: The Windows XP/2000 Answer Book: A Complete Resource from the Desktop to the Enterprise -- Chapter 18, 'DNS'
[John Savill]
This chapter examines installation and configuration of DNS servers on local intranets for local name resolution. You'll also get the scoop on local DNS configuration for forwarding external name resolution requests to different DNS servers. The extensive tips and notes make this interesting reading for beginners and veterans alike.
Restricting cached credentials
[James Michael Stewart]
Windows operating systems, including 2000, XP, and 2003, cache the logon credentials for the last 10 users. This allows for the user to re-logon at a later date even if the domain controller cannot be accessed at the time of logon. While this does represent a fault tolerance to DC downtime and network congestion, it is a poor state of security. Find out what the most secure settings are in this tip.
