Firewall, VPN and Internet Security
Today as organizations rush to get connected to the Internet, the importance of Firewall security is often overlooked. Many ISPs (Internet Service Provider) provide little or no security advice or support, leaving organizations to fend for themselves. The need is to often realize when it is too late, by intrusion or Internet abuse.
Firewall:
A firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules and is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass.
Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet. Many routers that pass data between networks contain firewall components and, conversely, many firewalls can perform basic routing functions.
Virtual Private Network:
A virtual private network (VPN) is a computer network that uses a public telecommunication infrastructure such as the Internet to provide remote offices or individual users secure access to their organization's network. It aims to avoid an expensive system of owned or leased lines that can be used by only one organization.
It encapsulates data transfers using a secure cryptographic method between two or more networked devices, which are not on the same private network so as to keep the transferred data private from other devices on one or more intervening local or wide area networks. There are many different classifications, implementations, and uses for VPNs.
Internet Security:
Internet security is a branch of computer security specifically related to the Internet. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing. Different methods have been used to protect the transfer of data, including encryption.
