Zero Trust Is A Model That Considers Access To Systems And Data Requires Permission, Not The Opposite Essay
Walking into a building does not typically grant someone access to everything that is inside. The zero trust model of cybersecurity works on a similar set of principles. It focuses on the idea that permission should be given on a much more specific level than trusting every device that connects to the network.
What Does it Mean?
The IBM article mentions that continuous verification, restricted privilege, and designing for the breach are essential elements of zero trust. The restriction element is related to the idea of making sure that one’s actions are legit and only allow them access to whatever they need.
It is important to keep in mind that this could apply to people and programs that have connected to the system. One example that the IBM article uses is for every application that is connected that has not yet been given the correct permissions, it should only be given just enough to get the job done.
In one of the examples, IBM also uses a school system that has a student logging in. This student does not necessarily need to be able to change all of the school’s payroll information. A lot of the time, these types of problems occur because some accounts get too many permissions at once, even if they are not expected to use all of them.
Needs Planning
Another thing that the article mentions is the fact that there is no easy technology plug-in that will make everything work together. IBM mentions that there are specific rules for each application, policy, operational process, and the infrastructure itself. This seems to suggest that before jumping into the process, an organization must make a plan of attack for each of the components previously mentioned. The point of making a restricted access system is so that it is not needed to let everything have full control. Something only needs access to what it needs to do its job.
Final Thoughts
Zero trust is a cybersecurity model that emphasizes the concept of permissions. Instead of letting everything connected automatically be trusted, it focuses on ensuring that everything will only have access to the information that it requires. Having the system require something to justify its presence can benefit the security of anything that needs protection. As long as technology continues to spread throughout the world, the importance of cybersecurity will only grow, and as one article mentions, the ability for a single program to access several things at
once is a huge problem to modern-day computer science. Organizations will continue to evolve as more and more applications are connected.
