HARDENING YOUR ROUTER IN 9 EASY STEPS | by Chris Cox

even keep the good guys in. Here are nine easy steps that you can
take to ensure that you have a brick wall protecting your network and
not an open door.

MULTICAST TREES | by Doug Downer

What do trees have to do with multicasting? Because multicast traffic
has multiple destinations, it forms a treelike pattern. This tip
illustrates what source and shared trees look like and how they work.

SWITCH UPGRADES | by Tom Lancaster

I suspect that a significant percentage, if not a majority, of
network administrators are sitting on switches that are a couple of
years old, likely purchased during the dotcom craze. They're almost
definitely 10/100 Ethernet, with plenty of ports for your users, and
you probably already have Gigabit uplinks, but still, it's been a
while, and you're thinking about upgrading. What should you do? Find
out why and what situations might warrant an upgrade.

IT'S A WINDOWS WORLD

that Windows is far from perfect when it comes to security. Microsoft
so routinely offers security patches and updates to fix one
Windows-related vulnerability or another that network and systems
administrators have come to expect them. This week, we focus on how
you can make sense of it all and keep your Windows-based network safe
and secure.
