Cybersecurity teams no longer follow the old approach of trusting users first and verifying them later. Now companies think that bad people can be anywhere inside their own company. This is why this security approach is a big deal now. It helps keep companies safe from bad people on the internet.
This security model focuses on verifying the identity of users and devices. Many companies, including banks and hospitals, use this approach to reduce the risk of unauthorized access to their systems.
Given this, more people want to learn about it. That is why there are a lot of resources about it now. Some are about how to make this security model work in a company. Others are about how to keep computers and clouds safe and how to make sure people are really who they say they are.
Here are six books about this cybersecurity model that are worth reading.
