VPN- What is Virtual Private Networking?
VPN is simply a way of providing secure communication using the (insecure) internet. There are two main types of VPN, namely Remote Access VPN and Site-to-site VPN.

Remote access VPN

Remote Access VPN allows remote workers access to centralised computer systems, usually when working from home or when travelling.

Why is remote working a good idea? British Telecom found productivity rose 31 per cent among its 9,000 teleworkers, due to lack of disruptions, stress and commuting time (source- The Telework Coalition).

In use, the remote PC or Laptop initiates secure encrypted communications with the central system, creating a secure TUNNEL (using encryption to 'scramble' the data) which prevents eavesdropping during data transmission, and authenticates the remote user.

SonicWALL can supply software called Group VPN client (GVC) which allows a remote/home PC to connect securely to your office network via the SonicWALL UTM. For info on SonicWALL Group VPN Client software, click here.

The latest range of SonicWALL UTM appliances come with ssl-vpn built in. This is a quicker and easier method of allowing secure remote connections without the need to install VPN client software. For Info on SonicWALL ssl-vpn, click here.

Site to Site (Office to Office) VPN

Site-to-Site VPN is used to connect two or more offices together in a secure manner. Again, authentication and encryption are vital parts of the process, to ensure that communication cannot be intercepted when travelling over the internet. Performance is also important- SonicWALL appliances have Dedicated VPN processors to handle the encryption processes quickly and efficiently. SonicWALL offers a wide range of VPN/UTM products, based on widely used IPSec VPN standards.

Online-edge can offer support and assistance to your organisation in choosing and installing the appropriate cost-effective and future-proof SonicWALL VPN solutions for both remote workers and to securely connect your offices.

Why not use a router or Windows Server for VPN ?

A possible problem with using a windows server as the VPN concentrator is that it may lack the processing power required. Unpatched Windows servers are prone to a number of vulnerabilities, which COULD affect the overall security of the VPN system.
Routers CAN be used as VPN concentrators, but again often lack the dedicated processing power required.
For these reasons, it's more cost-effective to install a dedicated SonicWALL VPN appliance which is purpose-designed to provide the performance, security and reliability required.

SonicWALL VPN- Benefits Summary

Here are just SOME of the benefits of allowing your workforce to access the main office network from a remote or home location-

 

Increasing productivity and profitability

Accessing emails, customer data, applications etc. can extend the working day and allow staff to use the power of your existing IT investment.

 

Reducing operational costs

By allowing secure remote access, workers can work from home, reducing the need for central office space and facilities.

 

Working green

By allowing secure remote access, workers can avoid time and cost involved in traveling to a centralised office.

 

Inherent Risks of Teleworking

Without IT oversight, home computers, personal laptops and mobile devices are more likely to be improperly configured for file and printer sharing, potentially exposing sensitive information to roommates, spouses and children. Teleworkers may not be using the latest operating system or application software. They may not have installed the latest security updates or kept up with their anti-virus definitions. All-in-all, personal devices are more likely to get infected by viruses or malicious code than corporate devices. And infections are slower to be detected and cleaned up on personal devices. Teleworkers increase corporate risks by potentially infecting other corporate machines and by spreading infections to customers and business

partners.
Worms and viruses cause damage by slowing down infected systems and networks, corrupting files and applications, and stealing bandwidth. Frequently, worms and viruses spread by e-mailing themselves to everyone in a user’s contact lists or by exploiting network connections. Worms often install a back door on the infected computer that can later be used by spammers for sending junk e-mail or to infect other unauthorized traffic on the network. Although most viruses are successfully controlled by corporate anti-virus software, they still pose significant risks to personal device users.
Trojan horses and zombies are malicious processes disguised as familiar objects, such as shareware programs, pictures or music files, so that even educated users feel safe launching them. Both Trojan horses and zombies may be dormant until a predefined event occurs and then are controlled by a remote hacker. For example, some Trojan horses let attackers control infected PCs remotely. Unless appropriate information security products are deployed, hackers can use this type of malicious software to access corporate resources through an unprotected VPN tunnel, unbeknown to the authorized user.
Additional risks come from the nature of home computing environments. Today, many home computers are connected to wireless home networks (based on IEEE 802.11 wireless LAN standard). Most wireless network equipment is shipping with Wired Equivalent Privacy (WEP) security features turned off (to simplify installation), and many non-technical people do not turn on even rudimentary encryption and authentication available with WEP. Since wireless networks extend outside of the physical property boundaries, anyone just outside of the building can eavesdrop on traffic going through the wireless network or access file shares. Furthermore, sophisticated hackers can easily defeat WEP by exploiting its widely publicized security flaws.
