The security of a system is crucial. Internet connectivity is essential for most companies, and therefore so is the need for internet security. With the use of a dedicated hardware Firewall, a security policy is designed, per company, to deny unwanted access from the outside world to the company's internal network and information.
Firewall security also plays a very important role in authorising access for staff using mobile technologies, and home based workers. Secure connections can be created across the internet. This type of secure connection is known as a Virtual Private Network (VPN). VPN technology requires specialised configuration to allow two devices to establish connectivity. Any information that is passed between computer devices, across an established VPN, is then encrypted to add another layer of security.
