Common blind spots when implementing Zero Trust

The mindset is focused on: “Never trust, always verify”

A security framework known as “Zero Trust” needs rigorous verification before providing access and operates on the assumption that all network traffic is untrusted. Putting "Zero Trust" into practice can be a highly effective strategy to ward off cyber dangers and data breaches. Organizations must understand these blind spots to better defend themselves from security breaches and data loss, which can make them vulnerable. Organizations can ensure their Zero Trust implementation is thorough and effective and reduce the risks and expenses related to security breaches by identifying and fixing those blind spots. It is very important to know about blind spots to identify and mitigate security risks and ensure a comprehensive and effective zero-trust implementation.

FAILURE TO IMPLEMENT PROPER NETWORK SEGMENTATION.

Network segmentation that works well is a key element of zero-trust security. It enables businesses to separate sensitive information and crucial systems from network locations with lesser extents of confidentiality. By creating secure zones that allow only authorized people and devices access to sensitive data and systems, organizations may lessen the potential damage from a security event. A network can be divided into different sections by utilizing VLANs, VPNs, firewalls, and micro-segmentation, among other techniques.

By isolating various types of network traffic from one another, organizations may precisely monitor and control the data flow, making it easier to identify and isolate problematic behavior. Additionally, by preventing malware or other hazardous software from propagating outside of certain network segments, segmentation can lessen the potential impact of a security issue.

POORLY ENFORCED ACCESS CONTROL RULES

The poorly implemented access control limits are another blind spot when implementing the Zero Trust security concept. Access control policies define who has access to what resources and under what conditions. They are a collection of rules and procedures. If access control restrictions are not appropriately enforced, attackers may be able to access sensitive data or systems.

Making an authorization choice should not be rushed since permission is perhaps the most significant procedure taking place within a zero-trust network. Every request or flow will eventually call for a decision to be made. The main systems that come together to create and influence such decisions are the databases and auxiliary systems that we shall explore in this article. Since they are collectively authoritative for access control, they must be carefully segregated. It is important to make a clear distinction between these roles, especially when choosing whether to combine them into one system, which is typically discouraged if at all feasible.

Inadequately implemented access control policies provide a blind spot from which attackers might get access to sensitive data and systems. Access control rules must be properly implemented via effective authentication, authorization, and access limitations to safeguard sensitive data and systems from unauthorized access.

NEGLECTING IDENTITY AND ACCESS MANAGEMENT (IAM)

When implementing the Zero Trust security architecture, another blind spot is ignoring Identity and Access Management (IAM). IAM is the process of controlling and safeguarding the users’ and machines’ identities when they use the resources of an organization.

IAM can be implemented using several techniques, including password management, just-in-time (JIT) credential creation, and identity and access management systems. While JIT credential generation is used to create and distribute credentials as needed, identity and access management solutions are used to maintain and safeguard the identities of users and devices. By employing password management, users can make sure that their passwords are strong, one-of-a-kind, and rotated on a regular basis.

IAM neglect can increase several security vulnerabilities. For instance, if IAM is not implemented correctly, attackers may be able to pass as legal users to access sensitive data or systems. In a similar vein, attackers may be able to access credentials that have been compromised if JIT credential generation is not employed. Additionally, if password management is not managed correctly, attackers may be able to guess or crack user passwords and obtain access to systems or sensitive data.

IMPROPER AUTHENTICATION PROTOCOLS

When implementing the Zero Trust security architecture, another blind spot is improper authentication protocols. Prior to allowing access to sensitive data or systems, authentication protocols are the collection of practices and technologies used to confirm the identity of a person or device. Attackers, however, might be able to access private information or systems if authentication mechanisms are not correctly established.

The methods used in authentication protocols include password-less authentication, single sign-on (SSO), and multi-factor authentication (MFA). As part of the MFA process, users must provide two or more kinds of identification to prove their identity. SSO is a procedure that enables users to only need to log in once to access various applications. A procedure known as passwordless authentication does not require users to memorize or type a password.

Implementing authentication systems incorrectly can result in several security issues. For instance, if MFA is not implemented correctly, attackers may be able to access systems or sensitive data by simply giving one form of identification. Like this, improper SSO implementation could allow attackers to use one set of credentials to possibly access several applications. Additionally, attackers may be able to access sensitive data or systems by intercepting or replaying authentication credentials if password-less authentication is not correctly implemented.

OVERLOOKING KEY HARDWARE ENDPOINTS

Another blind spot while adopting the Zero Trust security architecture is failing to pay attention to crucial hardware endpoints. To prevent them from becoming a security concern, hardware endpoints including Internet of Things (IoT) devices, employees’ cell phones, and other connected devices need to be appropriately controlled and secured. These IoT devices are frequently linked to a company’s network, and if they are not adequately protected, they can be exploited to access important information or systems.

Furthermore, if managed improperly, staff smartphones and other linked devices might pose a security risk. These devices are frequently used to access sensitive data or systems, and if they are not adequately protected, they may be utilized to do so.

Keeping track of all the hardware endpoints linked to a company’s network may be done with the aid of endpoint mapping. This method entails locating every connected device and tracking information about it, including its kind, access level, and location. Using this information, you can make sure that every connected device is securely protected and that any security concerns are found and reduced.
