Peer-to-peer file sharing can be a useful way to share files with classmates, family members or even strangers. However, peer-to-peer file sharing can also get you into trouble, so practice safe file sharing techniques.
Make sure you follow all legal guidelines.
Peer-to-peer file sharing can expose you to legal repercussions. If you share copyright-protected files, you could be breaking the law. The same thing applies if you download copyright-protected files. Avoid file sharing unless you know the files are safe and not legally protected.
Always use an up-to-date antivirus program when file sharing.
Safe file sharing requires that you always use an up-to-date antivirus program. Peer-to-peer file sharing is an easy way to unwittingly download and share virus-laden files and programs. Make sure your anti-virus program has up-to-date definitions, and always scan files before you download and install them. Avoid downloading program files unless you're positive that the source is safe, as executable files offer the easiest way to deliver a virus.
Check with organizational policies on file sharing.
Many organizations have strict policies on file sharing. If you're a college student, check with your university's policies on file sharing. The same thing goes if you're an employee engaging in file sharing at work. Even if you're not sharing copyright-protected material, you could be violating company or organizational policy, so know what's allowed before you share.
Use a strong firewall to protect your computer and network.
Some file-sharing applications offer a point of vulnerability whereby malicious hackers can attack your computer. Use a strong firewall to protect your computer and network when you're using file-sharing programs. Make sure the firewall covers unprotected ports, and keep your firewall up at all times. Windows comes with a firewall, but you may prefer to use third-party firewall software to customize your computer's protection.
Restrict your file-sharing to a single folder.
If you are sharing files, restrict your file-sharing to a single folder. Put all the files you want to share in that folder, and restrict access to that folder alone. If you don't restrict access, people can root through your computer and find any file you have, including files that contain sensitive personal or financial information.
Select the right file sharing application.
A big part of safe file sharing is based on selecting the right file-sharing application. Evaluate potential file sharing applications to find one that offers both the features and the safety to meet your needs. Many peer-to-peer file sharing applications work on the Gnutella file-sharing network. Gnutella is a decentralized file-sharing network to which various file-sharing applications can connect. Lime Wire is one of the largest peer-to-peer file sharing applications and is compatible with the Gnutella network. Try several different file sharing applications until you find one that meets your needs.
