Develop computer security policies and practices

Rather than tackling computer security threats like viruses and spyware individually, develop a comprehensive company computer security policy that addresses both systems and infrastructure and how people interact with them. Establish a hierarchical permissions system that states by department and job title which employees have access to which software and data and at what level. Implement password controls. Benchmark your company's current security profile and set goals for improvements. If you don't have the expertise on staff, bring in a computer security specialist.

Inventory assets as part of your computer security policy

You can't secure your systems if you don't know what they are, where they are or who's using them. Every hardware device - from computers and servers to cell phones, laptops and PDAs - must be inventoried and physically labeled as part of your computer security program. Pay special attention to hardware assets that are used outside the office, especially wireless devices. Scan all computers and servers to inventory software programs and user licenses. Set up a computer security program maintenance schedule and adhere to it rigorously.

Implement comprehensive computer security software

While many vendors provide computer security solutions to security threats on individual computers, look for a solution or combination of solutions that provides comprehensive protection for your entire enterprise. Any computer security program should include servers, networks, operating systems, Internet, email and wireless devices. A firewall, either software or hardware-based, is a must to prevent viruses coming in from the Internet.

I recommend: Consider small business security solutions like Symantec Endpoint Security and McAfee Total Protection Solutions. If your business is global, check out NTT America's Global Managed Security Solution.

Keep your computer security software updated

Computer hackers don't sleep and neither should your computer security software. It is important to stay current with security updates from all your software providers.

I recommend: Schedule regular Microsoft security updates.
