Computer viruses are all around us, infecting email messages, computers, and files.
Many viruses are just nuisances (such as popping up excessive advertising when you're surfing the web), but some can be very damaging and erase years of information.
O and O Systems looks at network security from a few standpoints:

-Education.

Educating the users about "safe computing" is our number one priority, because it is the most effective way to avoid problems.

-Virus Protection.

Nobody is immune.

Every computer should have a recent anti-virus software program installed, and the virus definitions should be automatically updated regularly.

-Firewalls.

Any connection to the Internet represents a potential opportunity for someone from the outside to try and "hack" into your network. Although no network security is completely secure against a dedicated hacker (remember, Yahoo, the CIA, and other huge web sites have been hacked!), we will set up a firewall and security arrangements which will minimize the risks.

-Internal Security.

Statistics show that your own employees are far more likely to create security problems than any outside intruder ever would. Secure servers, user permissions; activity logging, and minimizing data stored on individual computers are all ways to minimize this threat.

-Backups.

It is of critical importance to back up your data regularly to prepare for any number of catastrophes. Fires, floods, hardware failure, human error, hackers, viruses.
