Zero Trust for SMB

Zero Trust for SMB

Zero trust is a cybersecurity term that will become more pervasive over the next few years. As a small business owner, it’s an essential technology for you to understand because it will eventually be something you need to implement at the small business level. 

Zero trust represents a fundamental shift in the way organizations approach network security. The new security model assumes threats can originate from both inside and outside the network perimeter. 

Traditionally, network tools relied on perimeter-based security models like firewalls, which assume that devices inside the company are safe. The problem with this method is that once criminals breach the business network, they can often move through all the business data freely, stealing and encrypting it for ransom. 

Zero trust works through continuous monitoring of users and devices, follows the principles of least privilege, and uses strict multi-factor authentication (MFA).

Continuous Monitoring

The zero trust framework continuously monitors users and devices and periodically requires re-authentication to continue access to the business network. No user credentials or devices are automatically trusted. 

Least Privilege

Zero trust uses the principles of least privilege, so users only have access to the data they need to perform their jobs. Least privilege prevents attackers from moving throughout the network, allowing them to steal large amounts of business data. Some zero-trust models also utilize micro-segmentation, where sensitive data is stored in smaller segments requiring further authorization to access. 

Strict Multi-Factor Authentication (MFA)

Zero trust models all require some form of MFA for authentication. The extra step beyond a password can vary from text messages to authenticator apps or a security key. 

Zero trust has been in the news lately as federal officials discuss options to secure sensitive data and critical infrastructure. Eventually, zero trust principles will work their way down to small and medium-sized businesses, and your small business can implement many of the elements used in the model now!
