What is Zero Trust?

Applications are no longer restricted to conventional perimeters, and traditional security models are not equipped to handle digital transformation and remote workforces

A Zero Trust Security Model ensures better security and better compliance through an easy enforcement of granular access control, to secure users, devices, and applications.

What does a Zero Trust Model mean?

A Zero Trust Model is an overarching security strategy that assigns zero implicit trust to any user by default. All users, whether inside or outside the organisation's perimeters, are continuously validated, and authorised before granting them least privilege access.

Do not assume implicit trust for any user, situated anywhere, inside or outside the network

Treat every access request as unique, and continuously validate the context and risk of the request before granting access

Users get access only to those resources that they are allowed to access, and nothing else

Security teams get granular control over who accesses what and can formulate role based access policies

There needs to be complete visibility over all network traffic to identify threat vectors

How does the InstaSafe Zero Trust Model Work?

How does the InstaSafe Zero Trust Model Work?

Split Plane Architecture

A split plane architecture involves separating the control plane, where trust is established from the data plane, where actual data is transferred. This effectively removes enterprise data from the purview of the vendor, and since no enterprise data goes through vendor machines, data privacy is ensured

Server Blackening

SDP based Zero Trust models employ a drop all firewall. Drop-All firewall ensures that every data traffic coming to the IP address is dropped. It helps to ensure that no entity in the internet can get to know the presence of the IP address in the network, and blackens the network from the entire external internet

Single Message Authorisation

To ensure that the right authorisation data reaches the right device with the drop all firewall enabled, a single message authorisation process is used to relay authentication information and enable seamless secure access

Least Privilege Access

Users are only given access to what they are authorised to access, and nothing else. This methodology is used to limit insider threats and restrict the scope for lateral movement.

Understanding Zero Trust Security Model

Zero Trust is a combination of different security capabilities that aim to provide comprehensive security solutions to users accessing corporate resources securely either from inside or outside of the company perimeter.

Some of the Key Components of Zero Trust include:

Identity and Access Management (IAM)

Identity and Access Management (IAM)

IAM provides authentication mechanism considering the user identity and device identification. Multi factor authentication (MFA) provides additional security layer on top of single factor authentication of user identity

Micro-Segmentation

Micro-Segmentation

Entire network is divided into isolated segments which has its own micro perimeter. Each user is provided access to this micro segment based on access control rules and thereby limit the threat of lateral movement attack in case the user device is breached

Policy Engine

Policy Engine

Policy engine evaluates each user access request considering the parameters such as user identity, device identity and device posture, geolocation and user behaviour.  Access is provided on a “Need to Know” basis.

Network Visibility and Monitoring

Network Visibility and Monitoring

Complete visibility of all user activity and network activity with real-time monitoring giving 360 degree visibility of security posture of entire infrastructure.

Steps to Implement Zero Trust Network Access

Zero Trust is a journey which every organization needs to take a phased approach of Zero Trust implementation and work on continuous refinement.

There is a five step process for Zero Trust Implementation.

1

Define your protect surface

Build a Zero Trust architecture

Build a Zero Trust architecture

Based on network traffic flow, create a design that will best protect the assets. The design will determine how many gateways, placement of gateways and controller.

How does your enterprise benefit from adopting a Zero Trust Model?

A Zero Trust Model ensure better security, granting secure connectivity of critical applications, to users anywhere in the world

The identity centric approach followed by a Zero Trust Model helps in enforcing customised access policies for each user or device

All network traffic is logged for audit. Complete visibility into network traffic helps in better identification of vulnerabilities and threats

Implementing Zero Trust reduces operational, deployment, and maintenance costs by more than 40% in comparison to traditional solutions

Facilitate easy transition to remote work, easy outsourcing of business to 3rd parties, and easy migration to the cloud
