Don’t forget that your system can be a threat to others as well. There are lots of internet enabled viruses, worms and trojan horses that can create havoc over an always-on connection. Not running an up-to-date antivirus/anti-trojan horse detector could be costly.
If you’re a telecommuter, ensuring that your system is secure is doubly important. Corporate network administrators should assume that their remote users represent an inherent security threat, so keeping them on isolated network segments with strict monitoring, limited privileges and frequent password changes is good policy.
If you decide, for security or cost reasons, that you want to provide teleworkers with only limited access to work, GoToMyPC is one answer. GoToMyPC, which requires software to be installed on the work PC, lets the remote worker access files and applications from a web browser.
It is more than a remote PC access clone: first, the server installs on the PC you intend to access. During installation, this server registers with Expert City’s GoToMyPC broker. When the client initiates a GoToMyPC session, it first queries the broker, which then mutually authenticates with client and server, downloads a tiny applet into the client’s browser, and helps the client establish a highly secure connection with the home or office PC’s desktop server.
A less obvious security issue than keeping out the unwanted, is being careful about what your systems send out. Windows systems send out NetBIOS broadcasts and “mating requests” over the network, which can help attackers work out crucial details of your set-up for a later intrusion. Filter these and other similar traffic out.
