Norton's Internet Security Firewall: How It Works

  Like a barrier made of bricks and mortar, a firewall is designed to repel intruders: Instead of keeping out masked burglars, firewalls are one of several means used to keep cyber-criminals at bay.
  
  Firewalls initially were owned solely by large organizations but decreases in price, technology advances and home-users' rapid adoption of high-speed Internet access have led to growing sales of this type of solution.
  
  Norton Internet Security Firewall scans incoming Internet connections to make sure they are legitimate, do not contain viruses or other malware and are authorized.
  
  Since firewalls can be customized, what is banned at one company may be allowed at another: Educational institutions, for example, may need more Internet flexibility than an accounting firm.
  
  

Configuring the Software

  You can purchase the Norton Internet Security software directly from the site or request a CD version. Since some computers come pre-configured with another vendor's firewall, experts recommend disabling any pre-existing protection.
  
  The software will then walk you through the simple process.
  
  

More than a Firewall

• A firewall alone is not enough. To protect a home or company network from the ongoing onslaught, a network also should include anti-virus and anti-spam software, as well as ad blocking and protection from spyware, phishing, pop-ups, worms and intrusion.
