Unseen Attackers

Reason for concern

There are many security concerns for the mobile professional. Every mobile worker should be briefed on the basics of security. These concerns should be akin to keeping a wallet or purse secure, it becomes second nature for most people. Would anyone take their private files out of their file cabinets and post them on a billboard or hand them out to others? Probably not, but many of us are doing that every day with our electronic files. The issue of mobile security can be broken down into three categories: physical security, data encryption, and wireless security.

Physical security

One of the most obvious aspects of protecting electronic data and devices while traveling is their physical security. The best way is also the most simple; keep an eye on those electronic devices at all times. Some suggestions that may not be as obvious include bringing a locking cable while traveling. The laptop should be locked down while at remote locations or anywhere it may be left out of sight. The cables are not theft-proof, but are usually effective deterrents.

Encryption

Another important security measure that mobile workers should take is to encrypt their portable electronic devices. Laptop hard-drives should be encrypted with either Vista BitLocker, or a third-party program such as Pointsec. Users must know that encryption is easily defeated if the machine is logged in or left in a “sleep mode”. Encryption is only truly effective when the laptop is shut down and turned off. Also, it’s nearly useless if there is no password at boot-up.

Wireless security

Though the only sure way for a laptop to be secure when it is off, there are several tips for the mobile worker to stay safe when networking. In addition to using anti-virus software and firewall software, it is really not a good idea to connect to any wireless network or hotspot. If absolutely necessary to connect to a WiFi network that is not yours, at least do not connect to any adhoc network. This could easily be a stranger’s computer, and usually is. The best way to be safe is to use a more private connection, the type you would get when using a wireless broadband card. There are many aspects to staying secure, but these basics will set the framework and provide a good starting place.
