What is Zero Trust Security? Advantages, Disadvantages, Challenges and Solutions Explained
What is Zero Trust Security, with advantages, disadvantages & challenges and solutions.
What is Zero Trust Security?
Zero Trust Security is a security model that breaks away from the traditional perimeter security model that divides the network into “inside” trusted and “outside” untrusted, and always verifies access to all network traffic and resources, both “inside” and “outside” untrusted. The model is “untrusted and always verified”. The model is based on the principle of “Never Trust, Always Verify,” and it consistently and rigorously controls all access, regardless of internal or external network boundaries. There are zero-trust security products to realize this model, and many of them include features such as identity management, access control, and security monitoring tools.
Why is zero-trust security attracting attention?
Increasingly sophisticated cyber attacks
In recent years, cyber-attack methods have become increasingly sophisticated, and there are more and more situations in which traditional perimeter security alone is not sufficient to protect against them. In particular, phishing attacks and ransomware are becoming more common, requiring companies to take security measures.
Widespread use of cloud services
The use of cloud services is becoming more common, requiring security measures that go beyond on-premise boundaries. Zero Trust Security is an appropriate model for the cloud era because it can apply consistent security policies even in a cloud environment.
Increase in remote work
The Corona virus has led to the rapid spread of remote work. Zero Trust Security plays an important role in ensuring that employees can work securely from anywhere.
Basic principles of Zero Trust Security
Always verify
All access requests require user authentication and authorization verification. All communications are verified, including internal networks that are deemed trustworthy.
Principle of Minimum Authorization
Minimize damage in the event of a security breach by granting users only the minimum necessary access rights.
Application of multi-factor authentication (MFA)
Multi-factor authentication, which combines multiple means of authentication to verify user and device access, is applied. This provides strong authentication that does not rely solely on passwords.
Advantages of Zero Trust Security
Reduces
security risks with strong access control
Zero Trust Security strengthens access management through functions such as multi-factor authentication, single sign-on, and device certificates. This greatly reduces the risk of unauthorized access and information leaks, allowing you to build a strong security structure.
Supports flexible work styles and
contributes to improved productivity
Secure access can be secured regardless of location or device, supporting diverse work styles such as telework and BYOD. It can improve the level of security while maintaining employee productivity.
Usage monitoring and analysis and
log visualization
User access logs, SaaS usage, shadow IT, etc. are monitored in the cloud to detect behavior and prevent information leaks. And analyze logs of all systems including internal systems.
Disadvantages & Challenges of Zero Trust Security and its Solutions
While Zero Trust Security has the great advantage of enhanced security, it also has some issues in implementation and operation, and HENNGE One provides functions to solve these issues and facilitate smooth implementation of Zero Trust Security.
Disadvantages & Challenges #1
Increased implementation and operation costs
Implementing zero-trust security requires a review of existing security infrastructure and the introduction of new security products, which can result in significant initial and operational costs. In particular, trying to implement zero-trust security in an on-premise environment tends to increase costs further due to the complex network configuration and additional equipment required.
Solution #1
HENNGE One is,
Small start and cost-cutting
Because HENNGE One is a cloud service, initial costs are low and a small start is possible. In addition, since HENNGE One can be easily integrated with existing on-premise systems and cloud services, it can be deployed in stages. This enables the transition to zero-trust security while keeping initial investment low.
Demerit & Issue #2
Increased operational burden
The zero-trust security environment generates an enormous amount of security logs. Monitoring and analyzing these logs in real time to detect abnormal access and behavior requires advanced technology and human resources. This increases the burden on security staff and can make operations difficult.
Solution #2
HENNGE One is,
Easy-to-use management screen and automatic detection
HENNGE One provides an intuitive management console and visualization of security logs. In addition, a feature called HENNGE Cloud Protection (for Microsoft 365) dynamically analyzes and safely detects malicious behavior. This reduces the burden on security personnel and supports efficient operations.
Disadvantages & Challenges #3
Poor user experience
Since Zero Trust Security requires authorization, such as entering an authentication code, for all access, users may be frequently asked to authenticate or their access may be restricted. This reduces operational efficiency and can lead to user dissatisfaction.
Solution #3
HENNGE One is,
Contribute to a better user experience
HENNGE One’s service, HENNGE Lock, eliminates the need to enter complicated authentication codes each time, and allows users to complete authentication by simply tapping on a notification, thereby contributing to a better user experience in a zero-trust security environment. HENNGE One’s HENNGE Lock service eliminates the hassle of entering authentication codes. This solves one of the challenges of Zero Trust Security, which can lead to reduced operational efficiency and user dissatisfaction.
Zero Trust Security products offered through HENNGE One support this security model, helping to manage access and enhance security.
