The
diagram above shows what a safe home network could look like. In incorporates a
number of different hardware and software solutions that work together to help
keep the computer systems safe.
Step 1:-Install a Hardware Firewall/Router:The
hardware firewall/router is at the core of your system security. It is on the
“front lines” when it comes to protecting your systems. It’s main security
purpose is to let you get out to the Internet while keeping the Internet out of
your computers. While initially expensive, their price has dropped
significantly in the past number of years. In fact, I have seen them as
inexpensive as five dollars.
Step 2:-Secure Your WiFi:Computer
criminals love WiFi (or wireless network link) because it is so easy to set up
wrong. Anyone with a laptop, wireless network card, and software
available for free from the Internet can find unsecured Internet. Unsecure WiFi
data is then often uploaded to the Internet for everyone to see.
Step 4:-Install and Maintain Antivirus
Software:After a firewall, antivirus software is
probably the most important security feature you can have on your network. If
you don’t have antivirus software, stop reading and get it NOW! If you have
antivirus software, make sure that you keep it up to date. Antivirus software
is only as good as its last update. Do this daily if you can.
Step 5:-Install
Encryption/Secure Deletion Software:The purpose of this software class is to
prevent prying eyes from getting into your personal information. Encryption
software can make files, e-mail, etc. look like jibberish unless you have the
proper password or key. Secure deletion software makes sure that remnants of
your files do not lurk inside your computer, even afte they have been deleted.
