Security to Go

Whether logging into your small business network from a hotel room, airport, conference or tropical island, remote access is a vital aspect of taking your show on the road. While remote access opens up new opportunities, it also opens your network to security dangers at home and abroad.

Viruses and hackers can invade systems that are left vulnerable by insecure remote access. But taking proper security measures allows you to enjoy the flexibility of mobile computing without compromising your network. Several layers of protection are needed when securing your network for on-the-road use. Relying on one method of security can leave you vulnerable in other areas. To provide your network with the best possible protection, it's best to combine several methods.

Physical Security
To begin your security regimen, the devices you are using to access the network remotely must be physically secure. This means locking laptops, using hotel safes instead of carrying your laptop with you, and knowing where your devices are at all times. Aside from the obvious downside of property loss, if your laptop is stolen, the thief could access your network using your log-in. Securing your mobile computing devices is an important first step.

Passwords
While passwords obviously aren't foolproof, they definitely supplement an overall security plan when used appropriately. They are one more line of defense. Choose a password that is at least 7 characters long and includes alpha numeric characters, as well as punctuation. Set up your computer to require a password at startup, and protect your sensitive documents with a password as well.

Appropriate access
Confirm that remotely-used computers don't allow more access privileges than you require to do your job.

Software solutions
A personal Internet security solution, featuring intrusion detection software, will not only protect data from viruses and hackers, but will also provide additional levels of privacy and anonymity. Symantec's Norton Internet Security 2003 includes features to prevent Web sites from tracking online activities, keep personal information private, and block unwanted banner ads and pop-up windows to create a secure, private, and efficient online experience for both local and remotely connected workers.

The key component to intrusion detection and data security solutions is a personal firewall. This component acts as the gateway for incoming and outgoing data on all Internet connections. Norton Internet Security includes Norton Personal Firewall 2003, and this software is also available as a stand-alone solution. Firewall software protects data from unauthorized access and alerts users to attempted intrusions. Other benefits include the ability to block unauthorized Java or ActiveX components and cookies from unfamiliar sites. A firewall is particularly important to consider if a small business uses an "always-on" Internet connection such as DSL or cable, and if remote access is common.

Procedure protection
A security policy is essential to your business. It helps you examine all aspects of your network security and create standards of protection. A good security policy also enables you keep employees informed on safe practices. When creating your policy, include rules for practice such as password use, mandatory program updates like antivirus definitions, and guidelines for physical security during travel. Be sure to document, maintain, and publish the policy so it is available to all employees. It may be beneficial to have a training session on remote computing security so employees can contribute to maintaining safe connections.

The Holistic Approach
Remote-user protection and network integrity cannot be accomplished by focusing on individual aspects of data security. The ever-changing nature of the Internet and networked computing environments requires a constantly evolving and holistic approach to security management. By addressing each critical piece of the security puzzle as part of a comprehensive program, you can be free to roam without compromising your network security.
