Zero trust security architecture

Beginner’s Guide to Zero Trust Security Architecture 101

Here is the advantage of the Zero Trust Security Architecture for a possible cyber threat.

Zero Trust Security Architecture

The Zero Trust security model is not a standalone solution. It works in tandem with existing security solutions. This is to help organizations get the most out of their current investments and protect against a wide range of cyber threats.

The Zero Trust concept is built around Identity, Centric Security. It means that all access is based on the identity of the user or device. Most security systems today are built around providing access to resources and services based on IP addresses and ports.

Furthermore, this approach has been effective in addressing security challenges earlier but is no longer sufficient. In Zero Trust Model, access control policies are enforced dynamically. This is by context-aware technologies that are designed specifically for this purpose. 

Context refers to a set of attributes about the user/device being accessed such as location and time of day. The user/device is then matched against data attributes specific to each policy. These are the sensitivity level of information accessed, the risk profile of the user, and the compliance status of the device.

Based on these matches, access control decisions are made dynamically by applying the most appropriate security control. Also, in a combination of controls from a pre-defined policy set.

The Zero Trust Security Model

The zero Trust Security model is designed to address this problem. This is by enforcing policies based on one’s identity and the level of sensitivity of data accessed. It is also aimed at addressing problems related to user compliance, operational costs and complexity, and vendor vulnerability.

1. Identity-Driven Policy Enforcement: The principle that each user or device must be authenticated. This is before accessing any resource or service in the system. 

2. Context-Aware Access Control: The principle that access decisions should be made based on context. This is such as the user’s location and the sensitivity of the information being accessed at that moment. 

3. User/Entity Behavior Analysis: The monitoring of user/device behavior through advanced analytics techniques. These are machine learning (ML) and data mining (DM). It is then used by the system to dynamically enforce access control policies based on user/device behavior patterns. 

4. Adaptive Defenses: The principle that security controls should be applied proactively and reactively based on dynamic

ZTNA Architecture Identity-Centric Security

Zero Trust is a framework that allows organizations to take advantage of an identity-centric security approach to security. Zero Trust Security is an evolution of the traditional perimeter security model. It focuses on protecting resources from external threats by only allowing authorized users to access those resources through firewalls and proxy servers.

Furthermore, the Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) is an essential application. So, it provides all the necessary software, platform, and operating system, which makes it easy for users to build their applications. Furthermore, IaaS and PaaS are good options for hosting the server-side of your Zero Trust implementation.

Zero Trust Security is a paradigm shift. Hence, the focus is on securing internal systems and applications from internal threats. Also, the implementation of the Zero Trust Security Model requires architectural security monitoring.
