Firewall  Protection – computer and network

Firewall protection solutions play a central role in securing your computers or network from malicious Internet-based attacks. It is critical to select the right hardware or software firewall protection device to meet your business needs.

Connecting to the Internet can expose your business to malicious attacks from anywhere in the world. An Internet firewall security device can protect an individual computer or company network from these dangers. Creating an essential layer of protection between your business and the Internet, providing a secure environment in which your team can communicate freely with customers, partners, and remote users.

Understanding Firewall Protection

A firewall is a hardware or software device designed to protect the perimeter of your computer network or individual PC. Essentially, it creates a barrier between your network and the Internet. By intercepting each data packet being sent to or from your computer or network, it is able to use customisable rules to determine whether the data is safe or represents a potential threat. In the latter case, the firewall security hardware or software device immediately blocks that data from entering.

Internet firewalls protection devices fall into four broad categories: packet filters, circuit level gateways, application level gateways and stateful multilayer inspection firewalls. Each works at protecting a different layer, providing different levels of protection and functionality. Your firewall security specialist can assess your business needs and recommend the right level of internet firewall protection. It is important to remember that a firewall does not protect you against viruses, worms, Trojans and other Internet-borne nasties. You’ll need up-to-date anti virus software to protect against those.

A technology commonly incorporated with firewalls is the Virtual Private Network (VPN), which enables secure and authorised Internet-based connections between offices at different locations, and remote workers and the business network.

Business benefits of Firewall Protection Solutions

• An effective internet firewall security solution can protect your business computers, network and valuable data from a wide range of attacks including:
• Firewall security protects against ‘denial of service’ attacks, which can deprive you of access to network resources and destroy files
• Firewall security protects against ‘eaves dropping’, where hackers capture sensitive information as it’s typed at a keyboard
• Firewall security protects against ‘spoofing’, where hackers disguise themselves as a trusted computer to gain access to your systems.
• Firewall security protects against ‘Smurf’ -protection against LAN clients being used as part of the “amplifier network”
• Firewall security protects against connection or service requests that did not originate from the LAN side of firewall
• A firewall blocks Java, ActiveX, and Cookie portions of downloaded web pages
• A firewall blocks malformed IP packet attacks such as "Ping of Death", and variants such as "Teardrop", "Bonk", and "Nestea"
• A firewall blocks SYN flood and LAND attacks

In a number of cases, internet firewall solutions incorporate additional internet security features such as anti-virus protection, spam filter and content filtering solutions. This provides a more integrated internet security protection. Discuss these options with your firewall security specialist.

Note: It is essential to select the right firewall solution to meet your business needs, based on criteria such as size of network, expected traffic, number of remote users, level of protection required, level of encryption and more.
