One of the latest buzzword when it comes to cybersecurity is zero trust. You need to know what zero trust is and what it’s not.
Zero trust is a strategic effort that can help prevent a successful data breach by getting rid of the concept that the network architecture of a network is trustworthy. It is based on the principle to never trust and always verify. Zero trust is made to protect the digital environments by using network segmentation, prevention of lateral movement, and the simplification of granular user access control.
Conventional cybersecurity models work on the outdated assumption that everything inside the network of a company can be trusted. This is a broken trust model that assumed that the identity of a user isn’t compromised and that every user will act responsibly and could be trusted.
The zero trust model knows that trust is considered as a vulnerability. Once it is on the network, the users as well as the malicious insiders and threat actors can move laterally freely and exfiltrate or access all the data that they’re not limited to. Keep in mind that the attack’s infiltration point is generally not the target location.
You will identify a protect surface under a zero trust model. This surface is comprised of the most valuable and critical data, services, applications, and assets of a network. Each organization will have a unique protect surface.
Once you’ve identified the protect surface, you can determine how traffic will move across the company in relation to its protect surface. You can determine and set in place a policy that will ensure safe and secure access to your data. When you know the interdependencies between the users, services, infrastructure, and the DAAS, you can set up specific controls as near to the protect surface as you can. This will help create a microperimeter surrounding it, which will move together with the protect surface.
Zero trust does not depend on your location, the users, application workloads, and devices can be found everywhere and that’s why you cannot tie zero trust in a single location. It should be spread across the whole digital environment. You have to make sure that the right users will have access to the right data and applications.
Users also access data and application from different areas like small branches, offices, coffee shops, and even at home. Zero trust needs consistent control, enforcement, and visibility to be delivered through the cloud or directly on the device. You can prevent data loss and secure user access by having a software defined perimeter, regardless of where the users are located, which devices are used, where the data and workloads are hosted.
Workloads are very dynamic and they move across different data centers and hybrid, private, and public clouds. With zero trust, you should have a deep visibility into the interdependencies and visibility across devices, users, networks, data, and applications.
Many believe that achieving zero trust to improve their network security Wilmington NC is complex and costly. But zero trust is actually developed on your existing architecture and do not need you to get rid and replace your current technology. You will find no zero trust products. There are products that work perfectly well with zero trust environments. It’s easy to deploy zero trust. It’s easy to implement and maintain. You just need to identify the protect surface, map out the transaction movements, create a zero trust architecture, create a zero trust policy, and monitor and maintain regularly.
Zero Trust Access (ZTA) solutions exist for nearly every part of the network. However, a piecemeal approach to ZTA control leaves security gaps and is costly and cumbersome to manage.
The Fortinet Zero Trust Access (ZTA) framework leverages a tightly integrated collection of security solutions that enable organizations to identify and classify all users and devices seeking network access, assess their state of compliance with internal security policies, automatically assign them to zones of control, and continuously monitor them, both on and off the network.
“Zero trust” has become a buzzword in recent years, adopted by many different technology vendors. ZTA is an important pillar of an overall platform strategy that combines ZTA with security-driven networking, dynamic cloud security, and artificial intelligence (AI)-driven security operations. When organizations permit access under ZTA constraints, they confine users to the resources that are necessary for their role only. ZTA also stipulates the identification, monitoring, and control of networked devices, which are often more numerous than users.
With decades of experience in helping enterprises maintain security coverage for their rapidly expanding networks, Fortinet offers a highly effective ZTA framework that delivers visibility and control in three key areas: users on the network, devices on the network, and those users’ and devices’ offline activities.
Effective and Practical Identity and Access Management
Both legitimate network users and bad actors command the CISO’s attention, whether they are driving business success or jeopardizing it. For this reason, user identity management is a cornerstone of the Fortinet Security Fabric. Organizations can achieve complete user visibility and effective access policy enforcement with the Identity and Access Management (IAM) portion of the ZTA framework:
FortiAuthenticator serves as the hub of authentication, authorization, and accounting (AAA); access management; single sign-on (SSO); and guest management services. It establishes user identity through logins, certificates, and/or multi-factor inputs. FortiAuthenticator shares these inputs with role-based access control (RBAC) services to match an authenticated user to specific access rights and services. FortiAuthenticator also supports Security Assertion Markup Language (SAML) implementations, enabling users to securely access Software-as-a-Service (SaaS) solutions such as Salesforce, ADP, or Microsoft 365.
FortiToken provides two-factor authentication services to FortiAuthenticator, either through a hardware token or as a mobile solution. The mobile solution is an open authorization (OAuth)-compliant one-time password (OTP) generator application for Android and iOS devices that supports both time-based and event-based tokens. The zero-footprint solution makes it easy to scale multi-factor authentication implementations across the enterprise.
Whether the organization has a Fortinet Security Fabric in place or another security infrastructure, Fortinet ZTA solutions for user identity and access management provide robust security for the Fortinet Security Fabric.
Components of the Fortinet Zero-Trust Access Control Framework
Security for All the Things
The second objective of the Fortinet Zero-Trust Access solution is to maintain continuous visibility and access control of all devices on the network. This has been a considerable pain point for organizations. The growth in network device footprints is far outpacing the growth in network users—and certainly that of security teams. To help relieve those teams, Fortinet ZTA solutions provide integrated and automated discovery, classification, segmentation, and incident response.
Automated discovery and classification
The FortiNAC network access control solution accurately discovers and identifies every device on, or seeking access to, the network; scans it to ensure that it is not already compromised; and classifies it by role and function. FortiNAC can leverage existing agents to retrieve device information, but many organizations may not want to have to install agents at every location, in which case FortiNAC can communicate with the network initially, and then later identify devices.
FortiNAC can deliver dynamic network microsegmentation in a mixed vendor environment, supporting more than 170 different vendors and 2,400 different devices and interacting with the network to keep devices in the proper network segment.
FortiNAC also integrates with FortiGate NGFWs to enable intent-based segmentation. This is an approach to segmentation based on business objectives, such as compliance with data privacy laws such as the General Data Protection Regulation (GDPR) or Payment Card Industry Data Security Standard (PCI DSS) transaction protection. With intent-based segmentation in place, security teams can tag assets with compliance restrictions, which FortiGate enforces, regardless of where the assets move in the network, helping to reduce the time and cost of compliance implementation. Organizations may also use intent-based segmentation to maintain internal access policies when they restructure the business, without having to reconfigure the network itself.
Zero trust security model assumes that trust is transient; a device may be certified as trusted and then subsequently infected. Also, the applications it runs may become compromised. To maintain up-to-date trust statuses for all devices on the network, FortiNAC provides ongoing monitoring, with real-time incident response. Once it detects abnormal device behavior, FortiNAC can take a variety of countermeasures, such as reassigning the device to a quarantine zone so that compromised devices cannot serve as a staging ground for threat infiltration or data exfiltration, or put devices in a remediation network segment for the user to address whatever issue has been detected.
Protecting Assets on and off the Network
For end-user devices, such as laptops and mobile phones, Fortinet extends ZTA control to both on- and off-network operation through FortiClient.
Secure remote access
To enable secure remote access, FortiClient provides flexible options for VPN connectivity. It supports both secure sockets layer (SSL) and Internet Protocol security (IPsec) VPNs. A split tunneling feature enables remote users on SSL VPNs to access the internet without their traffic having to pass through the corporate VPN headend, as in a typical SSL tunnel. This reduces latency, which improves user experience. At the same time, FortiClient includes protections to ensure that internet-based transactions cannot backflow into the VPN connection and jeopardize the corporate network.
When end-user devices reconnect with the enterprise network, the FortiClient Fabric Agent shares endpoint security telemetry data—device operating system (OS) and applications, known vulnerabilities, patches, and security status—with FortiGate NGFWs and the rest of the Fortinet Security Fabric. This data helps the Fortinet ZTA tools refine the access rules for the devices.
The key to successfully implementing ZTA is to balance security and accessibility, since locking down the network is rarely an option. Fortinet ZTA solutions make it easier to accurately discover all the devices and users accessing the network and manage the associated security risks of each. This puts CISOs in a better position to support digital innovation (DI) initiatives that expand network access and leverage new network-connected technologies. Zero trust security needs to be more than a buzzword or a talking point. With the right solution, it delivers true business value.
Zero trust has become extremely popular these days. It’s crucial to understand what it is and what it’s not.
A zero trust security model is a methodical initiative that can help prevent data breaches by getting rid of the concept of trust from the network architecture of an organization. Based on the principle to trust no one and to always verify first, zero trust security is made to offer protection to modern digital settings by using network segmentation, stopping lateral movement, offers a layer 7 type of threat prevention, as well as the simplification of granular user access control.
Zero trust is made by John Kindervarg when he was still the principal analyst and vice president for Forrester Research, according to the realization that conventional security models work on the old assumption that all that’s within the network must be trusted. With this broken trust model, it’s assumed that the identity of the user isn’t compromised and that all users will act responsibility and could be trusted.
The zero trust security model considers trust as a vulnerability. When the network, as well as the users such as the malicious insiders and threat actors, can move freely laterally and then exfiltrate all the data that they’re not limited to. Keep in mind that the infiltration point of the attack isn’t the target location, in most cases.
You determine a security surface when it comes to a zero trust. It is comprised of the most valuable and critical assets, data, services, as well as applications in the network. The surfaces that are unique to every organization are protected. Since it only has what’s most important to the operations of a company, the protect surface much smaller than an attack surface, and it’s always recognizable.
Once the protect surface has been identified, you can now determine how the traffic moves within the organization according to the protect surface. Understanding who are the users, what applications are being used, and how they’re connecting is the only method to identify and enforce the policy that makes sure that the access to your data is secure.
Controls will be set in place as near to the protect surface as you can, which lead to the creation of a microperimeter, which moves the protect surface, anywhere it goes. Deploy a segmentation gateway to make a microperimeter. This is also known as a next generation firewall so that that only known and permitted traffic or legit applications can access the protect surface.
Achieving zero trust is considered by many as a complex and costly process. But, zero trust will be set up according to your company’s existing architecture and doesn’t require to you get rid of or replace the technology that you currently have. You will find no zero trust products. But you’ll find products that work cohesively with zero trust environments. There are also those that don’t. Zero trust isn’t difficult to deploy, execute, and maintain. You can do this using a five step approach.
In today’s ear that’s defined by mobility and the cloud, the traditional perimeter based security is no longer enough. Firewalls are not sufficient either when it comes to protecting the information of a company. That’s where zero trust comes in.
Data moves around a lot and it’s possible to be going back and forth to the cloud because it is going to be within your walls. That’s why companies are concentrating on multipronged methods to defend themselves against cyberattacks that come from various vectors.
If you consider the appropriate security architecture and methods to protect data, many of it just comes down to executing the basics appropriately, restricting access to only the ones that need it most, putting extra protection on the most confidential data, and ensuring that you know who is accessing what.
Security managers, unfortunately, continue to grapple with the complexity that comes from cobbling various cyber defence methods for network security. SOCs always scramble to stay on top of the alerts that streams across the consoles from various technologies.
Such solutions have to be combined and make sure that they work well with each other. Otherwise, there’s no way for the modern SOC manager to prevent the coming of silos while keeping themselves sane.
Zero trust network can help you with your company’s network security problems. It is an architectural and conceptual model that governs how security teams have to redesign their network. The zero trust model promotes a more holistic method to data security and adds more focus on the technologies and processes. The objective is to create secure micro perimeters, stronger data security through obfuscation methods, limiting the risks linked with too much user access and privileges, and enhanced security detection as well as response with automation and analytics.
It involves looking for cybersecurity solutions with certified integrations and automated orchestration abilities that will lower the operation problems on your team. You require tools that will inform one another without the need for human intervention that could detect threats correctly across the whole environment including all of the devices, the cloud, and your network.
Zero trust will give full breadth of services and products across cloud, network, and endpoint, needed to protect business from the kinds of advanced threats that are targeting them daily. And when threats are determined, orchestration abilities will simplify the task of responding them on all linked devices including mobile. This type of platform could either prevent a breach well before it takes place, or at the very least, identify it quickly and set in place the appropriate mitigation steps.
It aligns with the reality that data could be everywhere. Apart from the conventional data center and network, it could be in the cloud SaaS apps, Azuer, mobile devices, and even both personal and corporate, and thumbdrives.
Given the stringent compliance requirements especially after the pass of GDPR in Europe, platforms offer significant help here if to comes to enforcing identity, securing data, and access controls on network and devices, segmenting workloads and networks.
Today’s enterprises are dealing with constant change affecting different parts of their business. And far too often, the various solutions to these new realities do not align. This is especially true of business goals and cybersecurity policy. Traditionally, as your customers have maneuvered simultaneously to address rapidly changing business and consumer demands along with security threats, a compromise was made at the expense of cybersecurity.
However, as new threats evolve with enormous consequences for the bottom line, board members and C-level executives are shifting their focus to recognize the critical role network security must play in business, but without impacting either profitability and accessibility.
Competing Business Trends Facing Your Customers
This is easier said than done, as your customers need to be able to address several competing trends with a single solution. Speed, profitability, and business growth often appear to be at odds with compliance and security. However, for your customers to be successful, each of these trends must be addressed without hindering another.
Profit is the main objective of each business unit, and today it is increasingly achieved through speed, either in terms of responding to customer needs, managing inventory and production, or delivering critical services. This is why trends such as digital transformation and agile development exist. The consumers your customers serve expect instant accessibility and information.
If the profitability opportunity is met, the next challenge that your customers’ will face will be growth. In today’s digital business environment, this means that the infrastructure they have in place must be both scalable and elastic. Otherwise, growth and speed will be hindered, ultimately impacting both profitability and viability. To achieve this, infrastructures are being reworked to handle the increased traffic every couple of months, often through a combination of new technologies such as IoT, cloud-based infrastructure or services, and expanded data center resources and throughput.
With new, sophisticated cyberattacks targeting businesses of all verticals, especially targeting the constantly expanding attack surface, the nature of the security infrastructure cannot be ignored. A successful data breach can cause severe reputational damage; ransomware and DDoS attacks can knock organizations offline; and sensitive customer can be stolen, resulting in severe liabilities. Any of these will impact the bottom line. As a result, your customers need security solutions that enable growth and profitability, while securing their network and data. They just may not know where to look.
As your customers leverage new tools, such as connected devices and applications, they are collecting more consumer data than ever. As a result, a number of regulating bodies across the world have begun imposing strict new standards for data storage and protection. To avoid the fines and penalties that accompany non-compliance, your customers need security controls that ensure they meet these standards.
Security and Velocity
For security and compliance, the easiest solution would be to decrease network accessibility. However, this would be at direct odds with their business goals and needs. Network accessibility is integral to digital transformation efforts and employee efficiency. Similarly, security has often been seen by business units to be a hindrance to innovation. Part of the reason is that IT support teams typically add one-off isolated point solutions to the network to address the ‘threat of the day.’ However, the lack of communication between these devices can result in decreased network accessibility and visibility, as well as security efficiency, ultimately compromising performance. Ath the same time, however, C-level executives increasingly acknowledge the importance of mitigating data breaches and remaining compliant.
As a result, a recent study found that 43 percent of cybersecurity professionals agree that aligning the goals of the IT teams with those of business units is the most beneficial investment organizations can make. With Fortinet, it is now possible for your customers to align these four conflicting goals using an integrated Security Fabric approach to achieve both security and velocity without compromise either one.
The Security Fabric is an architectural approach to cybersecurity that provides comprehensive network protection without inhibiting business operations.
The Security Fabric allows your customers to deploy leading security solutions across their distributed environments that are also designed to communicate with one another in order to detect, prevent, and respond to threats in a coordinated fashion, regardless of where they occur. This broad network of solutions extends from the network perimeter, with next-generation firewalls and endpoint protection, into the cloud, with application security, CASBs, and more, and deep into the core of the network through dynamic network segmentation and powerful data center security technologies. Each device that makes up the Fabric is also regularly updated with the latest threat intelligence from FortiGuard labs, ensuring an automatic response the moment a threat or threat trend is detected. This comprehensive, intelligent security approach enables the network accessibility organizations need, and at the speeds they require, allowing genuine requests to pass through uninterrupted while stopping those that are suspicious.
The Security Fabric is also highly scalable. This means that as your customers’ business and networks grow, their cybersecurity policies and protocols will grow with it. Additionally, the Fabric is designed to evolve alongside emerging networking trends. So as new approaches such as intent-based networking gain traction across your customers’ organizations, the Fabric promises to deliver intent-based security to complement and protect those advanced network architectures.
Your customers need to be able to provide a seamless experience to their users, while meeting compliance standards and securing their network from data breaches through effective cybersecurity practices and zero trust network. While many of today’s traditional security solutions do not provide the flexibility and performance to meet these conflicting goals, the Fortinet Security Fabric offers intelligent and comprehensive security that allows for unprecedented growth, speed, profitability, and compliance.

Think about the regular network architecture of any organization. It’s typically a disorderly array of network connections going in every direction between different infrastructure devices on a legacy flat network. Each time the infrastructure needs a change, you should breathe deeply and open the network diagram, hoping that you could wedge the new requirements into this complicated environment. The cost and time to manage this network infrastructure appears to increase yearly. To deal with this dilemma, IT leaders turn to zero trust security and software defined technology. They are eager to make the most out of the simplicity as well as the cost savings but careful about the security implications.
Understanding Zero Trust Security
This new method of offering security for the company is built on the model of zero trust. The National Institute of Standards and Technology (NIST) said that a zero trust model will allow IT support experts to cease trusting packets like they were individuals and get rid of the concept of a trusted network as well as an untrusted network. When it comes to a zero trust network, all the network traffic will be untrusted.
That means, this new method involves authenticating first and providing access to the network next. It will be hard to carry out this method at scale for many different reasons.
The best place to begin on this zero trust security journey will be the wide area network or the WAN. According to the IDC, worldwide revenues will go up over the years. As you can see, the shift to the SD-WAN has created a lot of excitement. But, many IT support professionals are still not sure how to secure this kind of network. Let us begin with a few of the most common problem points and discuss how IT expert can deal with them by executing a secure SD-WAN.
Network Connectivity and Security
Among the most pressing and obvious benefits of SD-WAN is enhanced network security.
An SD-WAN could also help enterprises lower the cost of network connectivity by routing the company network traffic securely over public internet, getting rid of the need to pay for the costly private multiprotocol label switching (MPLS) circuits.
SD-WAN can help optimize your application and network performance by doing the following:
