A Deep Dive into Zero Trust: The Cybersecurity Staple in a Pandemic Era
Good day to you all, wherever you may be situated; your presence is highly appreciated. In today's digital landscape, we all ought to attribute ourselves as the cybersecurity warriors who bolster the nerve system of IT infrastructure across multiple organizations.
About Me
Please allow me to introduce myself. I'm Sophia Presi, a seasoned cybersecurity veteran with over 15 years of immersive experience primarily in compliance and risk management. I have been enormously involved in a range of diverse initiatives such as 'Women in Cyber' and 'InfoSec Girls.' Currently, I'm lending my expertise as a security evangelist at Insta.
Today's Session
Today, I will be discussing the increasingly pertinent topic of ‘Zero Trust'’. We will touch upon its significant aspects such as its subtle nuances, historical evolution, and the corresponding deployment models and use cases. My hope is that this session will offer insightful knowledge and aid you in understanding these concepts further.
Customer Challenges & Zero Trust
Given the increase in high-profile cyber attacks in recent years, Zero Trust has steadily climbed to be a signature security technology utilized across the globe. Companies are relentlessly grappling to overcome various challenges in their IT infrastructure, with the significant pain points diverging into four main categories: business continuity, security risks, performance, user experience, and a lack of access visibility.
Understanding trust as fundamental as having faith or confidence in someone or something, it brings us to the realization that trust, within itself can surprisingly be an exploit technique. Hence, to ensure cybersecurity, trust in a way becomes a burning boardroom issue under the CEO's eye given the stake of the business.
How Did We Get Here?
The legacy IT world was a closed network, with users, devices, applications, and servers boasting limited visibility. However, the fast-paced, interconnected world we live in today has diversified IT security tremendously, thus rendering traditional methods inadequate.
Why Zero Trust?
With the advent of cloud and mobility, the four key elements - users, devices, applications, and servers - remain disparate. Workers are now expected to access traditional LAN environments from various locations while the applications and servers span different cloud environments and data centers. Thus, to rein in this current state of business operations, we strongly need the 'Trust but Verify' approach brought in by the Zero Trust model.
The core principles of Zero Trust revolve around the simple mantra: 'Never trust users, never trust devices, never trust the network.' Several established frameworks are available to put it into perspective, such as Forester, Gartner, and Nest.
Deployment Models
To achieve a functioning Zero Trust model, we have four noteworthy deployment models:
- Resource-Based Deployment Model
- Enclave-Based Deployment Model
- Cloud-Rooted Deployment Model
- Micro-Segmentation Deployment Model
Each one provides unique benefits depending on the business needs and IT infrastructure in question.
Use Cases: Benefits of Using a Zero Trust Model
The Zero Trust model is particularly useful in several use cases such as secure remote access, VPN replacement, and secure access to multi-cloud and hybrid workloads.
Adopting a Zero Trust approach has several significant benefits:
- Protecting customer data & dramatically reducing the attack surface
- Providing an integrated security infrastructure
- Simplifying security and enhancing user experience
- Providing complete visibility into network traffic
In the current era, characterized by increased remote work and digital transformation, effective security solutions become critical. Traditional methods often fall short in addressing the security challenges that come with the increase in remote work. Foreseeing the gaps in these methods, many enterprises have opted to navigate towards the Zero Trust model.
