Networks at small and medium-sized businesses (SMBs), like most IT
components, can always be improved, updated and made even more
secure. But as new technologies promise to simplify your job, they
also add another layer of complexity to your network. A virtual
private network isn't secure with just a firewall. Wireless
networks work well -- but what about remote users? What about
networking tools that are made for large companies but scaled down
for SMBs? Are they OK?
This guide offers articles, tips and advice on just about
everything networking for SMBs. From simple definitions to security
options and VPN must-haves, this guide is a worthwhile beginning to
the seemingly never-ending network management challenge. Send us
your comments, questions and queries, and we'll do our best to
satisfy your networking needs.

NAC helps SMBs control network, costs
For large and small businesses alike, achieving optimal network
security is a never-ending quest. But small and medium-sized
businesses (SMBs), in particular, face many unique network security
challenges due to their smaller budgets and staffs. Among them:
- Access control: SMBs face special challenges in tracking
who has access to the network and if the level of access they have
is appropriately set.
- Malicious code: Most attacks against small businesses
are automated, and potentially debilitating to SMBs. These attacks
can appear as viruses, worms, Trojans and bots.
- Mobile device security: Mobile devices such as USB
drives, iPods and camera phones allow data and information to be
moved in and out of the network without normal access controls,
creating a definite security hazard.
One potential solution to these issues is network access control
(NAC). NAC offers administrators a way to verify devices meet
certain health standards before they're allowed to connect to the
network. Laptops, desktop computers or any device that doesn't
comply with predefined requirements can be prevented from joining
the network or can even be relegated to a controlled network where
access is restricted until the device is brought up to the required
security standards.
There are several different incarnations of NAC available. These
include infrastructure-based NAC, endpoint-based NAC and
hardware-based NAC.
