| Security |
|
Cable Modems are no more secure than any
other type of connection to the Internet. Although there's been an
increase in security concerns, the major issue remains the fact that
home users often don't even realize their systems are not secure,
and that permanent broadband connections become more popular every
day, exposing people to hackers for extended periods of time, unlike
dial-up connections. Under Windows, if you are not running a LAN (Local
Area Network), and your PC has "File and Print Sharing"
turned off, you should be comparatively safe on the Net. If, however,
you decide to run a Proxy, or any type of Server applications, if
you use File and Print Sharing, or if you are not even sure what this
document is about, please, make sure you take the time to read and
understand the issues at hand.

| File &
Print Sharing |
|
|
Don't use File and Print Sharing
unless you need it. You can check if it's turned on under "Start
> Settings > Control Panel > Network > File and
Print Sharing". If you have a LAN and need to share files,
follow the guidelines below:
- Unbind File and Print Sharing and Client for MS Networks
from TCP/IP - you will need to check all TCP/IP Entries
in "Control Panel > Network".
- Install NetBEUI and bind File and Pint Sharing to it.
- Turn access on just for the necessary directories/drives
and make it read-only.
- Use strong passwords for all your shares.
- Install a software/hardware firewall.

and Print Sharing" securely, check out these pages:

Proxy / NAT software
|
|
|
If you're running Proxy or NAT software
on your PC (to enable multiple PCs to access the Internet),
make sure you have all the security holes covered. Don't start
a Proxy server, unless you know what you're doing. NAT (Network
Address translation) is relatively more secure than Proxy, because
it assigns private IP addresses to the clients on your LAN,
acting as a firewall, however leaving the Server exposed. Check
the links at the bottom of the page for more information. on
NAT/Proxy software.

Firewalls
|
|
|
A Firewall is basically software
or hardware that filters all network traffic and blocks ports
in order to protect your PC or LAN from unauthorized entries.
Some firewall solutions include additional functionality that
allows you to detect and gather information about any intrusions.
There are different types of firewalls of different complexities,
however most of them allow for you to close unused ports from
being accessed externally.
Computers with Cable Modem, DSL or similar broadband connections
to the Internet are on-line much longer than those with dial-up
connections, which by itself increases the security risks
and justifies installing a firewall for protection. Here are
some firewall software options:
BlackICE
ConSeal
PC Firewall
SyShield
Tiny
Personal Firewall
Zone
Alarm
Although Town ISP recommends the installation of firewall
software, it is not supported by the Help Desk.
