3 Steps to Implement Zero Trust Cybersecurity

Cybersecurity is no longer an option for businesses; it's a necessity. Zero-trust is a cybersecurity strategy based on the principle that no one should be trusted automatically, no matter their position or role in the organization.Zero-trust encourages businesses to verify every access request, regardless of the user or application, to ensure that only authorized personnel gain access. The zero-trust framework can be applied to any business, regardless of size, industry, or location.

The three core principles of zero-trust are "continually verify," "limit access," and "assume breach and minimize impact." These principles give businesses a solid foundation to build a robust security framework. So, let's look at these principles and how they can be applied.

Step 1: Continually verify

The first principle of zero trust is to continually verify the identity and access privileges of users, devices, and applications. This principle is based on the idea that user trust should not be granted based on a user's position or role in the organization. Instead, businesses should verify the identity of every user and device that accesses their network, even if they have previously been given access before. Continuously verifying access privileges can prevent unauthorized access and reduce the risk of a data breach.

To implement this principle, businesses can use strong identity and access controls or identity access management (IAM), such as multifactor authentication (MFA), which requires users to provide more than one form of authentication to access their accounts. Another solution is implementing role-based access control (RBAC), which restricts user access based on job functions and responsibilities. By implementing IAM controls and continuously verifying access, businesses can reduce the risk of a security breach.

Step 2: Limit access

The second principle of zero trust is to limit access to prevent unauthorized access. This principle is based on the idea that users should be granted the least amount of access required to perform their job functions. By limiting access, businesses can reduce the risk of a security breach caused by unauthorized access to sensitive information.

To implement this principle, businesses can use Just-in-Time access (JIT), which grants access to users, devices, or applications only for a predetermined period. JIT access helps limit the time one has access to critical systems, reducing the likelihood of a security breach. 

Another solution is the Principle of Least Privilege (PoLP), which grants users, devices, or applications the minimum necessary access or permissions required to perform their job responsibilities. PoLP means users can only access resources or systems as necessary for their job functions. Finally, businesses can use Segmented Application Access (SAA), which restricts users from accessing unpermitted applications and prevents malicious users from gaining access to the network.

Step 3: Assume breach and minimize the impact

The third principle of zero trust is to assume breach and minimize impact. This principle is based on the idea that businesses should treat applications, services, identities, and networks as already compromised. By assuming risk, companies can take a proactive approach to cybersecurity, improving their response time to a breach, minimizing the damage, and protecting their business.

To implement this principle, businesses should prioritize incident response planning and invest in a comprehensive cybersecurity program. An effective incident response plan includes identifying potential risks, creating a response team, and establishing communication protocols to ensure a timely response. Additionally, businesses should conduct regular cybersecurity training for employees to educate them on best practices and minimize human error risk.

Partner with an IT service provider

The three core principles of zero trust – continually verifying, limiting access, and assuming breach to minimize impact – provide a practical and adaptable approach to cybersecurity for businesses of all sizes. By implementing these principles, companies can build a robust security framework that protects against cyber threats and data breaches.

Implementing a zero-trust framework can be daunting. However, companies can ease their burden by partnering with an IT service provider, like DKBinnovative, specializing in cybersecurity. DKBinnovative can leverage its advanced technologies and expertise to help businesses implement a zero-trust framework without hiring additional talent or adding additional tools. This ensures the zero-trust framework's smooth and seamless implementation.

Cybersecurity is critical for all businesses, and implementing a zero-trust framework can provide a solid foundation for a robust security framework.
