Network firewalls separate one network from another in order to eliminate the risk of one network infiltrating the other. With the increasing risk of intrusions by both outsiders and insiders, companies install robust firewalls like Sonicwall and separate their LAN segments from the internet with the use of internal firewalls. Newer firewall technologies are constantly being developed to overcome shortcomings.
Types of firewall technologies
It is essential to choose the right type of Sonicwall support options in order to remain fully protected from external and internal network intrusions. The most difficult to protect are intrusions by authorised users looking to gain access for illegitimate purposes. It is essential for the network administration team to evaluate their needs and take necessary precautions to prevent such attacks. There are two type of firewall technologies namely packet filtering firewalls and application proxies. Each type of technology has its advantages and disadvantages. Packet filtering technology is simpler and monitors traffic at the network level and below. Application proxies monitor traffic through all the layers in a network and were developed to eliminate the shortcomings of packet filters. These firewalls eliminate the need to allow direct connections from un-trusted networks to trusted networks.
Command line vs. GUI based firewall systems
Firewalls like Sonicwall use multiple techniques to provide complete protection to a network. However, it is important to consider various support options prior to choosing one. One of the most important issues is ease of use. There are GUI based firewall systems and there are command line driven systems. Many products are command line driven where the network administrator is in control of the firewall. Some products have add on GUI for those who prefer a GUI client for easy day to day administration. It can also limit the options available to users and eliminates the risk of an inexperienced administrator from breaking a firewall.
Balancing costs with protection
Most commercial firewall solutions offer various support options at an additional cost. This includes upgrades and twenty-four hour support in order to avoid any downtime caused by firewall defects. For companies, the cost of support is money well spent since it will ensure that their networks are not vulnerable to any type of attack. The final decision about support options will depend on the requirements of the organisation and the level of support required. Many companies may require immediate response while for others a turnaround time of several hours may be acceptable. The important thing is to choose the right firewall solution and adopt one with the knowledge of what long term support costs and expectations will be.
