Various Firewalls for Protecting a Business Network

Businesses operating PC networks and enabling staff to connect to the network both from the inside and outside use firewalls as a kind of security. A part from that, businesses can use firewalls to prevent the personal PCs that are part of the network, including employees' workstations and laptops, even the systems are not within the network.

Function

1. Firewalls protect unwanted access to network and to the objects within networks. Firewalls monitor the information packets that try to pass from the firewall and might reject packets that appear to be threats or other malicious code or that fail to meet some other category. Firewalls blocks access both in and out of a network. Useful when a business' network connects to the Internet so that remote users or staffs at branch offices can access it. In these cases, the firewall can enable the staff to access the network but restricts unwanted users to connect to the network from the Internet.

Types

2. Hardware dependent firewalls depend on specific hardware tools whose firmware performs the packet test and blocking processes. Software dependent firewalls depend on the PC systems they save, as in the case of the integrated firewalls in OS. As hardware-based firewalls use resources from devoted machines, and do not share a system's resources in the way that software firewalls do, they may be healthier On the flip side, firewalls dependent in the operating system can protect protection to mobile PC that employees use outside of the network. The 2 kind of firewalls are not mutually exclusive and can be used in groups. A Windows XP workstation may have integrated firewall activated and may also connects to a Windows network supported by a router with a hardware-based firewall.

Use

3. Businesses use firewalls to prevent their information, programs and systems. Businesses may have information that is necessary to the operation of the business itself like employee and accounting information and data about consumers, dealers and partners. Businesses use firewalls to make sure that hijackers cannot access programs and information from outside the business' network.

Advantages

4. Firewalls are division of a bigger set of security methods that businesses put in place. These methods include identity management platforms to make sure that users are who they say they are, anti-malware software like anti-virus and anti-spyware, and end-point biometric security systems like fingerprint readers. Firewalls are mainly beneficial in that they offer single-point-of-entry protection whose actions administrators can audit and record. Here, firewalls represent the first line of defense in preventing a business' digital assets.

Considerations

5. Businesses that use firewalls must identify that firewalls need maintenance and such maintenance needs a specialized skill set. Both hardware as well as software firewalls need patches and updates to works properly. At the same time, businesses must take care not to depend heavily on firewalls for security to the exclusion of other kinds of safety.
