As you are aware, many remote users will soon need access to the internal network and services. A remote access and virtual private network (VPN) plan is needed to connect it all together. The senior network architect has asked you to create the plan that will allow secure remote access to the internal network while preventing unauthorized access. He specifically requested that all information transferred between remote users and the organizational servers be protected against snooping
VPN encryption scrambles the contents of your internet traffic in such a way that it can only be scrambled using the correct key. IPSec connections require a pre-shared key to exist on both the client and the server in order to encrypt and send traffic to each other. The exchange of this key presents an opportunity for an attacker to crack or capture the pre-shared key.
SSL VPNs don’t have this problem because they use public key cryptography to negotiate a handshake and securely exchange encryption keys. But TLS/SSL has a long list of its own vulnerabilities like Heartbleed. Some SSL VPNs allow untrusted, self-signed certificates and don’t verify clients. This is particularly common in “clientless” SSL VPN browser extensions. These VPNs that allow anyone to connect from any machine are vulnerable to man-in-the-middle (MITM) attacks. However, this is not the case with most native OpenVPN clients. SSL typically requires more frequent patches to keep up to date, for both the server and client.
In the end, strong security is more likely the result of skilled and mindful network administrators rather than choice of protocol. Firewall traversal. All in all, for VPN users who have both options, we recommend going for IKEv2/IPSec first, then turn to OpenVPN should any issues crop up. The speed at which IKEv2 is able to negotiate and establish connections will offer a more tangible quality-of-life improvement for the average, everyday VPN user while offering comparable security and speed, but it may not work under all circumstances. OpenVPN/SSL was until quite recently considered the best VPN combination for most users of consumer VPNs. OpenVPN, which uses the OpenSSL library for encryption and authentication, is reasonably fast, very secure, open source, and can traverse NAT firewalls. It can support either the UDP or TCP protocol. IKEv2/IPSec presents a new challenger to OpenVPN, improving on L2TP and other IPSec-based protocols with faster connections, more stability, and built-in support on most newer consumer devices.
SSL and IPSec both boast strong security pedigrees with comparable throughput speed, security, and ease of use for most customers of commercial VPN services.
