Security concerns
Q: I hear the biggest security threat is someone hacking into my computer network through my Internet connection and stealing financial records (or worse, my identity). What concrete steps can I take to prevent this?
A: Your "biggest security threat" will depend on your situation. You need to implement a system that addresses your context.
If you have a single desktop computer, maintaining updated firewall and anti–virus software and keeping up with security patches of your Web browser will be sufficient in most contexts. Home and small office networks will also need firewall software at the router level and, in the case of a wireless network, properly configured encryption and access protocols. The initial home and small office networking products did not make implementing security easy, but the newer products have made significant steps towards making it so that those of us without degrees in engineering can do it on our own.
Laptop computers pose added layers of security issues. The elements that make a laptop valuable are also the things that pose security hazards. The proliferation of wireless Internet access in public places tremendously increase the utility of laptops by allowing you to be productive anywhere you go, but it makes maintaining and updating firewalls all the more necessary. And, of course, laptops are easy to steal, so the machine itself needs to be password–protected.
Also, when you're ready to dispose of the computer, don't forget to scrub it clean of any sensitive data on it. Unless you're going to grind up the hard drive, digital document shredding software is vital if when you retire a computer.
Finally, securing your computers from malicious hackers is not the last step. For many businesses, the biggest threat comes from untrustworthy employees, so systems need to be in place to restrict access to sensitive data only to those who need it. For many individuals and businesses, sloppy physical document handling can be a threat. Keep those shredders humming.
