Improving security with Zero Trust principles

Zero trust is a strategic framework every company can strive to implement that will strengthen security. The basics of zero trust are foundational and vital to the continued defense of your digital estate.

A crucial part of a successful cybersecurity strategy is determining where to place your organization’s focus. A good starting place is defining what precisely you are attempting to secure—your computer systems, user identities, corporate devices, information system processes, or sensitive data. Each area may require different tools or solutions, but all are important and should not be overlooked.

From there, your security team can start on the basics of zero trust and enhance security. The main goal is to secure data by restricting access, segmenting networks, implementing controls on devices and applications, and managing identities and permissions.

Zero trust secures your most valuable asset, your data

In the current threat landscape, one of the most significant risks comes from cyber criminals trying to gain access to sensitive data and lock you out of your systems, demanding a ransom, or extorting you with the threat of releasing private or sensitive organizational data. Zero trust in the security realm marks a shift from “trusted networks” to “least privileged access.” This principle states that no user, network, or device is ever implicitly trusted.

The prevalence of cyberattacks necessitates monitoring, restricting, and verifying access to your company’s most valuable asset: data. Cybersecurity professionals often do a lot to secure a device or system. However, the real target of cyber defense is sensitive data. The device is disposable if the data is securely encrypted.

How does Zero Trust work with a data-first security focus??

1. Discover, classify, and label all sensitive data. Securing vulnerable data begins with locating it in your organization’s environment. Who has access to it? How is it used? How does it move and flow through the organization? Once your team can answer these questions, applying zero trust principles begins.

2. Implement data resiliency. Data resiliency means applying encryption and creating redundancies that can be recovered during an attack through secure backups. Encrypted data can be stolen at rest, but it cannot be accessed, mitigating the damage of a breach. Along with a 3-2-1 backup strategy (three copies of data, on two different mediums, with one copy off-site), encrypting sensitive data is a surefire way to defang bad actors.

3. Establish proper access controls. This process follows the principle of least privilege, a crucial part of zero trust. To access a system, a user must have at least two forms of authentication (multifactor authentication or MFA). MFA is essential in implementing user authentication. Rather than relying on just a single factor, like username and password, which is something someone knows, it adds a layer of protection by requiring more than one form of authentication before granting access to systems or data. The factors are something a user knows (a password or security question), something the user has (like a smartphone for a one-time token), or something biometric (such as a thumbprint scan or facial recognition).

4. Authenticate continuously. User activity must be constantly monitored and flagged for suspicious behavior. A lot of today’s zero trust security solutions harness advanced AI and machine learning algorithms to detect suspicious activity like an unusual login or location (if your organization is located in San Francisco, California, a login attempt from Atlanta, Georgia, at 4 am PST could be an attack). These automated tools respond in real-time by requesting additional authentication or blocking access.

Data protection mitigates elaborate cyberattacks

Protecting sensitive data is no longer optional. In many cases, it’s a legal requirement and necessary for your organization. Zero trust principles offer a roadmap for more robust defenses against relentless cyberattacks.
