Choosing a VPN SSL VPN vs. IPSec VPNIf your organization is among the many that have struggled with the administrative headaches and costs of IPSec VPNs, going clientless sounds compelling. Given the demand for secure, easy, anytimeanywhere remote access for travelers and home office workers, the surge of interest in SSLTLS based VPNs isnt surprising. The key is deciding when to use IPSec and when to use SSL. Its not that one is right and one is wrong. IPSec and SSL VPNs both solve the problem, but SSL was a more tailored fit for us. Doug Torre Catholic Health System of Western New YorkIts not that one is right and one is wrong, says Doug Torre, who is rolling out Neoteris SSL VPNs to give 5. Catholic Health System of Western New York in Buffalo. IPSec and SSL VPNs both solve the problem, but SSL was a more tailored fit for us. Torre still uses IPSec VPNs for site to site connections, such as connecting remote sites to the core network. In choosing an SSL VPN over IPSec, Torre wanted to avoid the overhead of installing client software and to leverage one of SSLs strengths access to specific applications, rather than entire subnets. Were getting access to the exact thing we need, which is the application, says Torre, director of networking and technical services for Catholic Health System, which includes four hospitals and a number of long term health care facilities. Does all this mean that SSL VPNs are the way to go Everything being equal, who wouldnt want to reduce the cost of VPN ownership by eliminating client installation and configuration and centralizing policy administration, enforcement and access control Its not that simple, of course. Vendors promise to deliver secure access, but are SSL VPNs as secure and reliable as IPSecWhere do SSL VPNs fit into your network security policies, and which remote user communities can they best serve What does it really take to install and administer an SSL VPNSecuring Remote Access. Both IPSec and SSL VPNs can provide enterprise level secure remote access, but they do so in fundamentally different ways. These differences directly impact both application and security services, and shape the factors that will influence your decision on which technology to deploy, and where. IPSec VPNs protect IP packets exchanged between remote networks or hosts and an IPSec gateway located at the edge of your private network. SSL VPN products protect application streams from remote users to an SSL gateway. In other words, IPSec connects hosts to entire private networks, while SSL VPNs connect users to services and applications inside those networks. IPSec VPNs can support all IP based applications to an IPSec VPN product, all IP packets are the same. SSL VPN application services vary, because each product has its own way of presenting client interfaces through browsers, relaying application streams through the gateway, and integrating with destination servers inside the private network. Most SSL VPNs provide secure access to Microsoft Outlook Webmail, network file shares and other common business applications. However, they often require custom development to support nonbrowser based apps. Before you choose to deploy either or both youll want to know how SSL and IPSec VPNs stack up as security solutions, and what price you have to pay for that security in administrative overhead. IPSEC and SSL VPN Security Options. First, well compare how IPSec and SSL VPNs address three essential security requirements Authentication and access control. Each VPN type presents different options for user authentication, with clear implications for security. The Breeders Standard Pedigree Program For Rabbits there. The fundamental difference in how SSL and IPSec VPNs implement access control is an important consideration in where and how each technology is best applied. Defense against attack. Strong data confidentiality and integrity, and resistance to message replay and other attacks, are essential to make a VPN secure. Client security. The tunnel cant be secure if the host client is compromised. VPN client computers need strong AV and firewall protection, and admins need a way to check on the health of those systems. Next, well look at what it takes to configure and administer both IPSec and SSL VPNs, and the payoff for what you put into it Client vs. Its not necessarily a clear cut choice IPSec client administration and policy distribution headaches vs. SSL app customization. Integrating VPN gateways into your network. VPN gateways have to fit in to your network and play nicely with your app servers. What does it take Access Control and Authentication Both SSL and IPSec VPNs support a range of user authentication methods, including certificates. However, if you choose a noncertificate option such as password or tokens, you should be aware that the IPSec choices, as well see, are generally more vulnerable than the SSL alternatives. Accepted security best practices include allowing only that which is expressly permitted, denying all others. In a nutshell, SSL VPNs tend to be deployed with more granular access controls than IPSec, but that also means admins may spend more time configuring and modifying individual and group access rules. Authentication. IPSec employs Internet Key Exchange IKE, using digital certificates or preshared secrets for two way authentication SSL Web servers always authenticate with digital certificates, no matter what method is used to authenticate the SSL client. Both support certificate based user authentication, though each offers less expensive options through individual vendor extensions. They differ significantly on how these extensions are implemented, and SSL is the more secure solution for companies that decide to implement noncertificate user authentication. IPSec vendors, for example, offer alternatives such as Extended Authentication XAUTH and L2. TP over IPSec. However, XAUTH, which is frequently deployed using preshared group secrets and DHCP, is vulnerable to several known attacks. And while L2. TP over IPSec is embedded in Windows 2. XP, it isnt broadly supported by VPN gateways or used by non Microsoft shops. Most SSL vendors support passwords and tokens as extensions. Further, SSLs encrypted tunnel protects the users identity and credentials, making asymmetric authentication more secure than IPSec with XAUTH. SSL is better suited for scenarios where trust is limited or where installed certificates are infeasible business partner desktops, public kiosk PCs and personal home computers. Access control. If you really need per user, per application access control, go SSL. If you need to give trusted user groups homogenous access to entire private servers and subnets, go IPSec. IPSec standards support selectors packet filters that permit, encrypt or block traffic to individual destinations or applications. As a practical matter, most organizations grant hosts access to entire subnets, rather than keep up with the headaches of creatingmodifying selectors for each IP address change or new app. SSL VPN products tend to provide more granular tools how granular varies from product to product but how you use them and how much administrative cost youre prepared to shoulder is up to you. Because they operate at the session layer, SSL VPNs can filter on and make decisions about user or group access to individual applications ports, selected URLs, embedded objects, application commands and even content.
