Firewall Virus Protection - Stop Internet Intruders at the Gate

Firewall virus protection can be in the form of computer security firewalls at the individual level. At the corporate level firewall virus protection takes the form of network security firewalls. Firewalls that conform to PCI data security standards and based on a HIPAA security risk assessment of the firm's needs create a formidable barrier to unauthorized intrusion, data theft, identity theft, internet viruses, hackers and other agents of cyber crime.

Firewall virus protection is designed to prevent hacker intrusion, commonplace in an internet environment populated with high speed connections and unscrupulous hackers. High speed connections due to increased online time and static IP addresses are a hacker’s paradise. Unless adequately protected, DSL or cable internet connections leave your computer gates open to unwelcome visitors. These hackers steal financial and personal details and can infect your computer with malware like viruses and worms.

Among the essentials for capping security vulnerabilities are antivirus programs, host and network intrusion detection programs, email security software and of course firewalls. Firewall virus protection is important both at the individual and corporate level, often saving companies embarrassing downtime and financial losses.

Hardware firewalls and software firewalls are the two types of virus protection firewalls available. Hardware firewalls take the form of cable/DSL routers. Though installation is tricky, they are low on maintenance time required from the user. Software firewalls are programs that watch your computer for suspicious activity and notify you so that you can take action to terminate it.

Though firewalls are an essential part of your computer defense system, most will not scan your computer for viruses. Software firewalls often come with built in virus protections that scan for and disable computer viruses. This is a comprehensive firewall virus protection system that is able to both prevent and cure malicious software or malware. Another option is to combine your firewall with an antivirus program to provide a comprehensive computer security system.

In the context of network security, firewalls protecting networks of great value, a comprehensive security policy for intrusion detection, prevention and elimination use firewall virus protection as one element in a chain of protective elements. Security policies for large establishments delineate zones of trust divided by firewalls. An example of a zone of no trust is the internet. A zone of high trust would be the internal network.

Network layer firewall virus protection relies on rules that allow or disallow packets to pass through the firewall based on rule matching. The rules may be inflexible or may be user defined. Some firewalls also make use of negative rules that allow packets as long as they do not match any of the defined negative rules. Firewalls can define rules based on a number of attributes like protocols, TTL values, domain name of the source, netblock of originator, and of course source and destination IP addresses.

Firewall virus protection is like taking medication that prevents unwanted viruses from entering the system. To eradicate viruses you need firewalls with built in antivirus or a separate antivirus. Firewalls should be considered your security guard at the gate. A good firewall is one based on a security risk assessment and conforms to data security standards. A good firewall has many of the same qualities of a good watchman. It lets the good guys in and keeps the bad guys out. It is smart and adapts to changing needs. Protection from virus attacks and intruders is well worth the money.
