What are the primary advantage of SSL over IPsec?
SSL VPNs are scalable in that they can be quickly deployed to remote users regardless of machine or location, but IPSec is more scalable in terms of its transparency to the network. From the user and application perspectives, the secure network (once established) is indistinguishable from a trusted LAN.
What are pro and cons of SSL vs IPsec?
Each type of VPN has its pros and cons. The main difference between IPsec and SSL VPNs is the endpoints for each protocol. While an IPsec VPN allows users to connect remotely to an entire network and all its applications, SSL VPNs give users remote tunneling access to a specific system or application on the network.
Is SSL part of IPSec?
The IPsec protocol suite operates at the network layer of the OSI model. It runs directly on top of IP (the Internet Protocol), which is responsible for routing data packets. Meanwhile, SSL operates at the application layer of the OSI model. It encrypts HTTP traffic instead of directly encrypting IP packets.
Which is easier to set up, SSL or IPsec?
IPsec VPN solutions are generally easier to set up and manage. Apart from the VPN app installations, everything else is hands-free on the client side, and users only need to switch on the VPN clients to gain secure access. The same cannot be said of SSL.
Can you use IPSEC tunnel and TLS at the same time?
It doesn’t make sense to use both at the same time. Yes, IPsec tunnel “dissolves” at the edge routing firewall, but in the similar fashion TLS “dissolves” inside DMZ, usually HTTP server, i.e. if I am a hacker I would not bother with site-to-site network layer secured pipe nor TLS transport layer pipe from edge firewall to DMZ HTTP server.
When to use application level encryption over IPsec?
When using an IPsec tunnel you would still want application level encryption. This is advantageous if there is a gap between the end of the tunnel and where your session ends. The following diagram describes why you may want application level encryption like HTTPS (SQL in my example) in addition to IPsec.
What does IPsec stand for in VPN protocol?
IPsec (Internet Protocol Security) is a VPN protocol that encrypts and secures data sent over the internet. IPsec VPNs provides great data authentication, confidentiality, and integrity.
