Entrust is perhaps one of the most trusted layered security experts around. Aside from securing digital information for consumers, enterprises, and governments in 2,000 organizations spanning 60 countries, the company also recently announced that it will begin delivering a more streamlined SSL VPN certificate deployment for customers of Check Point Software Technologies. Keep reading to discover why this new feature is important, and what it means for users.
Entrust already provides its clients with SSL authentication, fraud detection, shared data protection, and e-mail security, but according to the company's press release, this new feature will enable users of the Check Point Connectra "secure remote access gateway" to have a brand new way to set up their own Entrust SSL VPN certificates, which are needed for encrypted sessions. Essentially, SSL VPN protects any and all types of data that may be in transit, which reduces the risk of hackers being able to access personal or classified information.
About SSL VPN
A VPN is a virtual private network, which is a computer network that has links between nodes that are carried by open connections or "virtual circuits" in larger networks; one example of this is the Internet. This is unique because usually these links run across a single, private network. In a similar vein, an SSL VPN -- or secure sockets layer virtual private network -- is a type of VPN that operates on secure sockets layer technology and is available through https over regular web browsers. SSL VPNs enable users to establish safe and secure remote access sessions from any Internet-connected browser.
The secure sockets layer functions between two layers: the TCP layer and application layer protocols. SSL VPN solutions enable companies like Entrust to deliver the level of corporate network access necessary for each person that connects. Essentially, SSL provides a secure connection between remote users and internal network resources.
SSL VPNs basically leverage the presence of security sockets layer encryption technology, which is built into just about every web browser. In comparison to IPsec, which works at the IP layer, SSL sits above the transport protocol.
VPN gateways identify themselves with a digital certificate that includes basic -- yet important -- information, such as the name of the authority that issued the certificate and the server's public encryption key. This gateway then sends an encrypted session cookie to the browser, which begins the communication. In order to generate the encryption key that will be used for the session, the client encrypts a random number with the server's public key, which will then send the result to the server to be decrypted with a confidential key.
Once an identity has been authenticated, SSL VPN, like the IPsec VPN, enables a user-specific level of access, which has usually been pre-determined based on a company's policy concerning its employee's ranking. For example, the head of a company's human resources department would obviously have access to employee payroll information, while a receptionist at the same company would not.
