Peer-to-peer (P2P) file-sharing allows users to share files online through an informal network of computers running the same software. File-sharing can give you access to a wealth of information, but it also has a number of risks. You could download copyright-protected material, pornography, or viruses without meaning to. Or you could mistakenly allow other people to copy files you don't mean to share.
If you're considering P2P file-sharing:
- Install file-sharing software carefully, so that you know what's being shared. Changes you make to the default settings of the "save" or "shared" folder might cause you to share folders and subfolders you don't want to share. Check the proper settings so that other users of the file-sharing network won't have access to your private files, folders, or sub-folders.
- Use a security program from a vendor you know and trust; keep that software and your operating system up-to-date. Some file-sharing software may install malware or adware, and some files may include unwanted content. When necessary, it can clean up your pc from malware.
- You may want to adjust the file-sharing program's controls so that it is not connected to the P2P network all the time. Some file-sharing programs automatically open every time you turn on your computer and continue to operate even when you "close" them.
- Consider setting up separate user accounts, in addition to the administrator's account, if your computer has multiple users. Limiting rights on user accounts may help protect your computer from unwanted software and your data from unwelcome sharing.
- Back up data you don't want to lose in case of a computer crash, and use a password to protect any files that contain sensitive information.
P2P File-Sharing: Evaluate the Risks
Every day, millions of computer users share files online. Whether it is music, games, or software, file-sharing can give people access to a wealth of information. To share files through a P2P network, you download special software that connects your computer to other computers running the same software. Millions of users could be connected to each other through this software at one time. The software often is free.
Sounds promising, right? Maybe, but make sure that you consider the trade-offs. OnGuard Online cautions that file-sharing can have a number of risks. For example, when you are connected to file-sharing programs, you may unknowingly allow others to copy private files – even giving access to entire folders and subfolders – you never intended to share. You may download material that is protected by copyright laws and find yourself mired in legal issues. You may download a virus or facilitate a security breach. Or you may unwittingly download pornography labeled as something else.
