Ways to Protect Yourself
from Online Threats
If
you use the Internet you have a significant chance of suffering computer damage,
financial loss, or both because of a computer virus or spyware that gets onto
your computer without your knowing it. In recent years, the Internet has become
a place where anything goes and there is hardly any regulatory oversight. You
now face assaults through e-mail, Web sites, messaging services, and downloads.
Americans invested more than $1 billion in protection software over the past
year, and they still spent more than $4 billion for computer repairs, parts, and
replacement to solve problems caused by viruses and spyware. These problems are
so extensive and serious that they prompt over 7 percent of all computer
purchases.
A
disturbing fact is major, well-known companies have supported spyware by
using it as an advertising medium. We have had spyware infections so bad
that we have had to erase the hard drive to get it off. There is a 40%
chance that you have spyware on your system and not even know it. Another
40% of you know you have spyware, but cannot get it off your system. A
good source of information on spyware is Computer Associate's Spyware
Information Center.
There
are also risks of spam and the scams known as phishing--sending fraudulent
e-mail that solicits confidential information by impersonating a reputable
institution. Approximately
80% of total email delivered is SPAM.
Through
good practices and the use of protection software, you can greatly reduce your
exposure online.
- Because you are constantly exposed to different sources of viruses
(for example, the Internet and email), MedTech recommends regularly
scanning your computer for viruses.
- Be careful about what
free programs you install. Often the software is free because it
contains a spyware payload funded by advertising money.
- Use a spam filter. A
great free one is SpamBayes, but you must train it. Consider an ISP or e-mail provider that
offers security. AOL, EarthLink, MSN, and Yahoo offer spam
filtering and virus scanning for e-mail at no extra charge for users. Use them as one layer of a multilayer defense. Check other ISPs’
sites to find out what they provide. MedTech can provide spam and
virus filtering for you on your own domain.
- Use one e-mail address
for family and friends, another for everyone else. You can get a free
address from Hotmail, Yahoo, or a disposable-forwarding-address
service such as SpamMotel.
When an address attracts too much spam, drop it.
- Do no send personal
information because of an e-mail request.
- Never respond to
e-mail asking for personal information.
- Never open links in e-mail to access personal accounts.
- Don’t reply to spam
or click on its “unsubscribe” link. That tells the sender that
your e-mail address is valid.
- Never open an
attachment that you weren’t expecting, even from someone you know.
- Do not keep spammers
in business by purchasing a product or service advertised through
spam. Even if the offer isn’t a scam, you are helping to finance and
encourage spam. If you receive spam that promotes a brand, complain to
the company behind the brand. The truth of the matter is if spam
didn’t work, there would be no spam.
- Don’t post your
e-mail address in its normal form on a publicly accessible Web page.
Otherwise, spammers’ address-harvesting software can easily read
your e-mail address and you will start getting spam.
- Enable the automatic
Windows Update feature if you haven’t already done so. Go to www.microsoft.com/protect
and download and install service packs, which offers enhanced
security. For earlier versions of Windows, run Windows Update from the
Start menu. The vast majority of viruses and spyware programs have
targeted Windows-based PCs, which far outnumber Macintosh computers.
So using a Mac can minimize your risk. Even so, keep your Mac up to
date via the Software Update Control Panel. Also regularly update your
Web browser and other major software, using the manufacturers’
update instructions or features.
- Use antispyware
program. If you are looking for a free solution, download and install the free Microsoft Windows Defender from www.microsoft.com/protect,
but avoid other free antispyware, because often spyware masquerades as antispyware. Keep your subscription to new spyware definitions current and regularly update the definitions or use the automatic update feature.
- Use antivirus
software. You
can obtain additional virus protection from ISPs, directly from a
manufacturer’s site, or at a retail store. Enable the auto-protect
and automatic update features and keep your subscription current. http://www.free-av.com is a good free antivirus software for home and non-commercial use only.
- Use a firewall.
We highly recommend a hardware firewall, which costs $30 to $40. Your
router most likely has a built-in firewall. Change its default
password and disable “remote administration” to prevent hackers
from seizing control of the router. A
firewall router can limit the access of PCs within the network by
blocking specific ports.
- If you use Internet
Explorer, keep its security level at medium or higher to block Web
sites from downloading programs without your authorization or
automatically running Windows active scripts.
- Regularly back up
personal files.
This safeguards your data in case of a security problem. Consider
using a plug-in external hard drive as your main or backup storage, so
that if the computer becomes disabled, you’ll already have your
files off the machine. MedTech offers a service called HIPAA Backups
that will automatically do this for you.
- Download only from
online sources you trust. Be wary of ad-sponsored or “free” screen
savers, games, videos, toolbars, music and movie file-sharing
programs, and other giveaways; they probably include spyware that may
damage your PC if it gets through your security.
- Children who share and
download files should do so on a PC that doesn’t contain
confidential information or valuable data, such as financial records.
- Avoid short
passwords. To
foil password-cracking software, use passwords that are at least eight
characters long, including at least a numeral and a symbol, such as #.
Avoid common words, and never disclose a password online. Not only is
this wisdom, if you are dealing with data that falls under HIPAA
regulations, this type of password will meet HIPAA requirements.
