Transport-layer security is more effective than its predecessor SSL, and its latest version - TLS 1.3 - improves both privacy and performance.
IPsec is faster than OpenVPN, so if both client and server support IPsec, use IPsec. Use External Authentication ¶ For user-based authentication, the most efficient method of user management for large numbers of accounts is an external authentication source, such as a RADIUS server, LDAP server, Active Directory (Via LDAP or RADIUS/NPS), etc. SSL VPN (Secure Sockets Layer virtual private network): An SSL VPN (Secure Sockets Layer virtual private network) is a form of VPN that can be used with a standard Web browser. In contrast to the Nov 19, 2011 · IPSec. IPSec operates at the Network Layer by extending the IP packet header. IPSec is a framework for multiple services (Secrecy, Data integrity etc.), algorithms and granularities. IPSec uses multiple algorithms to make sure that in case if one algorithm fails to secure anymore, there are other options as backup. In this section of Data Communication and Networking – Security in the Internet: IPSec, SSL/TLS, PGP, VPN, and Firewalls MCQ (multiple choice) Based Short Questions and Answers ,it cover the below lists of topic, All the Multiple Choice Question and Answer (MCQs) have been compiled from the books of Data Communication and Networking by The well known author behrouz forouzan.
Set up Mobile IPsec for IKEv2+EAP-TLS¶. With the certificate structure prepared, the next task is to configure the necessary IPsec settings. The settings below have been tested and found to work, but other similar settings may function as well.
Jan 01, 2008 · Currently, the two most common techniques for creating VPNs are IPsec and SSL/TLS. In this article, I describe the features and characteristics of these two techniques and present two short examples of how to create IPsec and SSL/TLS tunnels in Linux and verify that the tunnels started correctly. TLS is over a reliable transport (typically TCP), while IPsec is over an unreliable transport (IP, which can drop and reorder packets). What this means is that TLS keeps context between the sender and the receiver and updates that state (such as the sequence number); with IPsec, all that needs to be made explicit (as there is no guarantee that IPsec can hide also the IP datagram's header itself, so you can avoid the attacker to do traffic analysis. Both things that with TLS you cannot do. You cannot use IPsec with NAT, because the latter modifies values in the headers which interfere with the integrity checks done by IPsec. Most IPSec-based VPN protocols take longer to negotiate a connection than SSL-based protocols, but this isn’t the case with IKEv2/IPSec. IKEv2 is an IPSec-based VPN protocol that’s been around for over a decade, but it’s now trending among VPN providers.

Hopefully that helps with HTTPS and S/MIME, now on to TLS: When we reference HTTPS today, we commonly say HTTP over SSL, but this is just because that term is widely popular and the most recognized when referring to HTTPS. In reality when you by an "SSL" certificate from say Symantec, GoDaddy, Verisign you are actually purchasing a TLS certificate.
