Traffic Filtering: Stateful, Stateless, and Something Between

In this article, we will highlight the difference between stateless and stateful traffic filtering. Moreover, we’ll delve into various traffic filtering approaches that are stateless in nature but try to emulate stateful: ACLs, Reflexive ACLs, Cisco ACI contracts.

IPsec vs. OpenVPN — what are the differences?

Quick answer: IPsec is a suite of secure network protocols that are based on open IETF standards and OpenVPN is an open-source protocol that is used by an application with the same name. In other words, IPSec is a framework but OpenVPN is an end-user solution. It doesn’t follow that OpenVPN is worse than IPsec. If OpenVPN as a solution fulfills your requirements it could be the best choice for you. The strength of IPsec lies in three words: open IETF standards. By meeting these standards, two different implementations from different vendors can successfully operate together in the most secure way without having a single common line of code.
