The constant threat of cyberattacks has made network security a top priority for companies in every sector, with Gartner predicting that global cybersecurity spending will reach $188 billion in 2023. However, security continues to get more challenging due to factors like a rise in remote work, an increasing reliance on touchless internet of things (IoT) devices, and the overall decentralization of enterprise networks. It’s hard to create a secure perimeter around the enterprise when its users, devices, applications, and data could be anywhere in the world.
The zero trust security methodology addresses this challenge by shrinking the focus from one large security perimeter and instead creating smaller “micro-perimeters” around each individual resource that needs defending. It’s called zero trust because it follows the principle of “never trust, always verify.” That means each user and device needs to verify its identity and prove its trustworthiness before it can penetrate the micro-perimeter. So, for example, if a cybercriminal uses stolen credentials to log into the enterprise network, they have to pass through many different security checkpoints to see or access any sensitive resources, which increases the likelihood they’ll get caught before excessive damage is done.
