How Businesses Can Achieve Zero Trust Security

Enterprise Security Magazine | Tuesday, October 05, 2021

Zero Trust solution can minimize security complexity, save money, and decrease time to identify and remediate breaches.

FREMONT, CA: Before being granted or retaining access to applications and data, every user, whether inside or outside the organization's network, must be verified, authorized, and continually checked for security configuration and posture. Zero trust implies no typical network edge, and networks can be local, cloud-based, or a blend of the two, with resources and workers located worldwide.

To validate the user's identity and maintain system security, this model utilizes sophisticated technologies like multi-factor authentication, identity and access management (IAM), identity protection, and next-generation endpoint security technology. When assets and endpoints connect to apps, Zero Trust expanded includes data encryption, securing email, and validating the hygiene of assets and endpoints.

Why is Zero Trust important?

One of the most efficient ways businesses limit access to their networks, applications, and data is to use zero trust. It incorporates preventative approaches such as identity verification and behavioral analysis, micro-segmentation, endpoint security, and least privilege controls to discourage would-be attackers and restrict their access during a breach.

Instead of assuming that a connection through VPN or SWG is safe and trustworthy, possessing the technologies to distinguish ordinary versus abnormal activity helps enterprises tighten authentication laws and regulations.

Tips to Achieving Zero Trust

Assess the organization

Define the attack surface and identify sensitive data, assets, applications, and services (DAAS) within this framework. Detect and audit every current credential available in the business, remove outdated accounts inactive for more than 30 days, and review all the rights for risk and consequence. Examine the company's existing security toolset and look for any vulnerability in the infrastructure.

Develop a directory of the assets and map the transaction flows

Identify where sensitive data is stored and who needs access to it. Analyze how different DAAS components communicate and ensure that security access controls between these resources are compatible. Users should be aware of how many service accounts they have and where it is necessary to connect. Examine every authentication method and remove or increase connection difficulties on any obsolete or insecure systems, like LDAP or NTLM. 

Establish a variety of preventative measures

In the case of a breach, use several precautionary measures to discourage hackers and prevent their access.

Monitor the network continuously

Determine the source of the abnormal activity and pay attention to everything going on around it. Without interruption, inspect, analyze, and log every traffic and data. Detect and store anomalous or suspicious traffic and activity by escalating and keeping authentication logs. Have a transparent approach in place to deal with service account and other essential resource behavior issues.
