In Part I, I provided some background information on the OSI layer, some of the protocols and on security. In Part II, I’ll be discussing the different network security protocols: IPsec, TLS/SSL and SSH.

Network Security Protocols: Background – Part I

As an IT security professional, one of the areas where I gained a significant amount of knowledge and experience in is network security.  Working for a telecommunications company, it’s pretty much a given that if you are working in security, you are dealing with network security protocols such as IPsec, SSL/TLS and SSH.   I started off primarily working with IPsec and eventually was exposed to TLS and finally, SSH.  One of the real issues that I first encountered was differentiating between these network security protocols.

  • “Which one shall I use?”
