FIVE REASONS WHY ORGANISATIONS NEED A ZERO TRUST ARCHITECTURE
The realities of 21st-century enterprise networking required a new paradigm and in 2010 , John Kindervag , an analyst at Forrester Research , wrote a paper that popularised the idea of the Zero Trust architecture . Over the next few years , as enterprise computing evolved to embrace cloud computing and the problems with perimeter security became more pressing , the concept of the Zero Trust architecture gained traction . Amr Alashaal , Regional Vice President – Middle East , A10 Networks gives five reasons why organisations need Zero Trust architecture .
In the late ‘ 80s through the early ‘ 90s , network security was simple ; once an entity ( a person , a machine , a process ) that was inside the envelope of your network and authenticated with your security service ( typically the computer you were using ) it was assumed that entity was , henceforth , trustworthy . This security architecture is called perimeter security . This architecture worked well because there were no external connections to your network and the network itself wasn ’ t complicated .
This simple security architecture couldn ’ t last for long . By the late ‘ 90s , these networks began connecting to the Internet , paving the way for websites and email becoming mainstream . By the 2000s , hundreds of service providers began offering software-as-a-service ( SaaS ), which has become a strategic component of enterprise business operations . Now , the envelope of the network is no longer as clearly defined . Consequently , network security challenges became much more complex .
State of network security to around 2010
The network no longer had a single , unbroken network perimeter . It had become ‘ porous ’ to support mobile and remote workers , as well as business partners and new third-party services .‘ One and done ’ authentication of entities requesting access became inadequate for the new and more complex network security demands .
You could no longer assume that anyone on your network , including your staff , could be trusted .
