What is a VPN?

A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed MAC address, the hacker can also intercept information meant for another user.

2) Data Sniffing

Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured networks, such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools, are often built into operating systems and allow the data to be viewed in clear text.

3) Man in the middle attacks

Once the hacker has either sniffed or spoofed enough information, he can now perform a “man in the middle” attack. This attack is performed, when data is being transmitted from one network to another, by rerouting the data to a new destination. Even though the data is not received by its intended recipient, it appears that way to the person sending the data.

These are only a few of the methods hackers use and they are always developing more. Without the security of your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the Internet will often pass through many different servers around the world before reaching its final destination. That's a long way to go for unsecured data and this is when a VPN serves its purpose.

A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Router, for instance - in different networks that allows private data to be sent securely over a shared or public network, such as the Internet. This establishes a private network that can send data securely between these two locations or networks.

This is done by creating a “tunnel”. A VPN tunnel connects the two PCs or networks and allows data to be transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection secured by encrypting the data sent between the two networks.

VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. Using industry standard encryption and authentication techniques - IPSec, short for IP Security - the VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual Private Networking can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN Router using any computer with VPN client software that supports IPSec, such as SSH Sentinel.)

There are two basic ways to create a VPN connection:

encryption: encoding data to prevent it from being read by unauthorized people

IPSec: a VPN protocol used to implement secure exchange of packets at the IP layer

RV082 specifications

The Linksys RV082 is a robust dual WAN VPN router that stands out in the market for small to medium-sized businesses seeking reliable network connectivity and security. Designed to meet the demands of a dynamic business environment, the RV082 offers a host of features that enhance both performance and reliability.

One of the primary attributes of the RV082 is its dual WAN capability. This feature allows businesses to connect to two different internet connections simultaneously, ensuring uninterrupted internet access. In case one connection fails, the router can automatically switch to the other, minimizing downtime and maintaining productivity. This failover capability is essential for businesses that rely heavily on internet connectivity.

The RV082 also boasts impressive VPN support, enabling secure communication between remote users and branch offices. With support for up to 50 simultaneous VPN connections, the router accommodates a growing workforce that may require access to the company’s network from remote locations. This is particularly beneficial for businesses with telecommuting employees or those that operate across multiple locations.

Security is a paramount concern for any business, and the RV082 addresses this with various built-in security features. It utilizes advanced firewall capabilities, including Stateful Packet Inspection (SPI) and Denial of Service (DoS) protection, safeguarding internal networks from external threats. The router also supports strong encryption protocols such as IPSec and PPTP, ensuring that sensitive data transmitted over the VPN remains secure.

Performance-wise, the RV082 includes eight switched LAN ports, allowing numerous devices to connect directly to the network without the need for additional hardware. This feature simplifies network management and helps keep connectivity organized. Furthermore, the router supports Quality of Service (QoS) prioritization, which allows businesses to allocate bandwidth effectively among different applications and users, promoting seamless performance even during high traffic periods.

The user-friendly web-based interface facilitates easy configuration and management, making it accessible for users with varying levels of technical expertise. Additionally, the RV082’s compact design ensures that it can fit into nearly any office environment without taking up too much space.

In summary, the Linksys RV082 is an excellent choice for businesses looking for a dependable and secure networking solution. With its dual WAN capabilities, extensive VPN support, robust security features, and user-friendly management tools, the RV082 successfully meets the challenging needs of modern business networking.
