Linux VPN Server
For IPSec VPN, the user access control is realized by examining five network parameters (source IP, source port, protocol, destination IP, destination port). Due to these obvious advantages mentioned above, SSL VPN is being adopted by more and more individuals and companies. However, this does not mean that SSL VPN is the suitable solution for every case. Because SSL VPN was originally designed for web-based applications, it may not be a good solution for network services like FTP and Telnet, though some vendors have developed new functions to solve this problem. Thanks to the simple plug-ins like Firesheep, even a school going kid can hack your connection and take away whatever you are trying to access on hotspot connection. What can we do to protect ourselves on Public Wi-Fi The answer to this is also VPN. The growth in businesses worldwide has triggered a trend of dispersed workforces. Now more employees than ever work remotely while connecting to centralized servers in head offices and regional offices, thus having a regular flow of information between their system and centralized servers. This unsecured flow of information does not only risk the privacy and security of the flowing information but it risks the information stored on centralized servers and your system, thus making the entire data vulnerable to hacks. Therefore in order to have secure remote access to the centralized servers, the best solution is Dedicated - Static IP VPN which not only encrypts the flowing information, but also builds a secure tunnel for the information to flow while restricting the remote access to server through those dedicated IPs only. The RADIUS server will authenticate each dial connection as an authorized telecommuter. Once that is finished, the remote user will authenticate and authorize with Windows, Solaris or a Mainframe server before starting any applications. There are dual VPN concentrators that will be configured for fail over with virtual routing redundancy protocol (VRRP) should one of them be unavailable. Each concentrator is connected between the external router and the firewall. A new feature with the VPN concentrators prevent denial of service (DOS) attacks from outside hackers that could affect network availability. The firewalls are configured to permit source and destination IP addresses, which are assigned to each telecommuter from a pre-defined range. Virtual Private Network or VPN basically adds a layer of security to your internet connection hence making the flow of information more secure and private. More technically, VPN encrypts your information before it leaves your system and to the point it reaches your requested destination. With the exponential growth and availability of the internet, the need of the security and privacy of the internet is also at all high. Netizens now require tools to hide their identity and information from hackers and trackers who are after it and in order to do so, we tend to go for security and privacy tools. One of the best tools to secure your online identity and flow of information is VPN. With the immense growth in the availability of the internet on public Wi-Fi's in Cafes, Streets and Universities, our information is at all time high risk. Most Linux based VPN servers come with many options and a very thick instruction manual.
