Risks of File-Sharing Technology
File-sharing technology is a popular way for users to exchange, or "share," files. However, using this technology makes you susceptible to risks such as infection, attack, or exposure of personal information.
What is file sharing?
File sharing involves using technology that allows internet users to
share files that are housed on their individual
computers. Peer-to-peer (P2P) applications, such as those used to
share music files, are some of the most common forms of file-sharing
technology. However, P2P applications introduce security risks that
may put your information or your computer in jeopardy.
What risks does file-sharing technology introduce?
- Installation of malicious code - When you use P2P
applications, it is difficult, if not impossible, to verify that the
source of the files is trustworthy. These applications are often used
by attackers to transmit malicious code. Attackers may incorporate
spyware, viruses, Trojan horses, or worms into the files. When you
download the files, your computer becomes infected .
- Exposure of sensitive or personal information - By using
P2P applications, you may be giving other users access to personal
information. Whether it's because certain directories are accessible
or because you provide personal information to what you believe to be
a trusted person or organization, unauthorized people may be able to
access your financial or medical data, personal documents, sensitive
corporate information, or other personal information. Once information
has been exposed to unauthorized people, it's difficult to know how
many people have accessed it. The availability of this information may
increase your risk of identity theft .
- Susceptibility to attack - Some P2P applications may ask
you to open certain ports on your firewall to transmit the
files. However, opening some of these ports may give attackers access
to your computer or enable them to attack your computer by taking
advantage of any vulnerabilities that may exist in the P2P
application.
- Denial of service - Downloading files causes a significant
amount of traffic over the network and relies on certain processes on
your computer. This activity may reduce the availability of certain
programs on your computer or may limit your access to the
internet.
- Prosecution - Files shared through P2P applications may
include pirated software, copyrighted material, or pornography. If you
download these, even unknowingly, you may be faced with fines or other
legal action. If your computer is on a company network and exposes
customer information, both you and your company may be liable.
How can you minimize these risks?
The best way to eliminate these risks is to avoid using P2P
applications. However, if you choose to use this technology, you can
follow some good security practices to minimize your risk:
- use and maintain anti-virus software - Anti-virus software
recognizes and protects your computer against most known
viruses. However, attackers are continually writing new viruses, so it
is important to keep your anti-virus software current.
- install or enable a firewall - Firewalls may be able to
prevent some types of infection by blocking malicious traffic before
it can enter your computer . Some operating systems actually
include a firewall, but you need to make sure it is enabled.
