Are you interested in learning how to build a cybersecurity mesh?
The landscape of technology has transformed majorly in the last few years. The latest technological advancements have also affected the operation of businesses and this shift in usage trends has given rise to new concerns. The top on the list is cybersecurity.
The security breach of an internal network at Ubers and the ransomware attack on a medical center in Texas in September 2022 are some of the latest cyberattacks examples highlighting the issue’s significance.
Why Build a Cybersecurity Mesh Architecture?
Today businesses are relying heavily on multi-cloud infrastructure and edge computing for reliable, scalable, and efficient data storage and processing.
Although bigger organizations with complex IT infrastructure may find it difficult to completely migrate to fully decentralized systems, they are pushing for a more distributed business model.
For the previous few years, the remote working model is also getting increasingly popular among enterprises that are either going for a completely remote or a hybrid working environment for their employees.
Nevertheless, the horizon of such companies is extending beyond a fixed perimeter with a distributed workforce.
The expanded business network and resources call for equally distributed yet robust security strategies. Cybersecurity mesh is one such cybersecurity solution for distributed technology and business models.
Let’s see what is cybersecurity mesh, how to build one, and the related advantages.
What is Cybersecurity Mesh?
Cybersecurity mesh is an architectural approach to ensure the security of remotely distributed assets. The security approach is scalable, flexible, and reliable. The four main layers of cybersecurity mesh are:
Security Analytics and Intelligence
It focuses on using security tools that detect cyber threats and vulnerabilities, trigger appropriate responses to these threats, etc. The insights from the data collected from these tools help in better understanding the current security protocols and improving them further.

Distributed Identity Fabric
It helps distinguish between the actual network users and the malicious attackers. It provides decentralized identity management, identity proofing, adaptive access control, etc.
Consolidated Policy and Security Posture Management
It is a central point for the security department of the organization to control the security protocols everywhere.
These dashboards provide a comprehensive view of the whole system and allow security teams to take timely actions when required.
Build a Cybersecurity Mesh
Next, let’s see how you can build a cybersecurity mesh for your organization.
As stated, cybersecurity mesh is a composable and scalable approach to ensure maximum security of IT resources whether remote or on-site through an integrated security framework. You can adopt certain practices to enforce such a security mesh in your organization.
Some of these security practices are the following:
Identify Your Attack Surface
The foremost task is to analyze your current system for security gaps and vulnerabilities. This includes all your organization’s assets, including computing resources, storage, and sensitive data.
Next, you will prioritize the significance of each resource along with the severity of the associated risks. Such a detailed analysis will help you put more effort where it’s required.
Invest in Reliable Security Tech Stacks and Tools
Implement a detailed security system through reliable technologies. This will include digital security protocols, software analysis, monitoring tools, counterattack software routines, etc.
You will likely choose from the following tech stacks for your enterprise security:
Information security ensures that your business data is safe and secure from any unwilling leakages and unwanted breaches. Some techniques to ensure information securities are data loss prevention and email security.
Your security team can implement data loss prevention measures for stopping the unwanted transfer of data out of the organization. This includes extensively labeled data storage, access, and sharing protocols.
Email security focuses on securing email communications from cyberattacks like phishing, spam emails, viruses, etc.
Authentication protocols help in implementing application-level security. Authentication techniques like password management and multi-factor authentication help ensure no unauthorized users enter your organization’s system.
MFA uses a secondary device to authenticate and let in an authorized user, whereas password management focuses on the timely updation of user account credentials with stronger passwords, etc.
Perimeter security guarantees your organization’s internal system and networks are secured from the external environment. Application firewalls and unified threat management ensure such perimeter security.
Your security team can implement a unified threat management system through intrusion detection, spam detection, content filtering, etc., to prevent any attacks from entering your premises.
A web application firewall ensures cloud security too by securing communication and data transfer between your cloud resources and user applications.
Network security includes timely monitoring of the network. Continuous network monitoring enables the security team to proactively identify vulnerabilities and threats and take preventive security measures.
Your security engineers can implement systems like SIEM (Security Information and Event Management) and NDR (Network Detection and Response).
The monitoring of entering and leaving traffic data packets helps in actively detecting malicious data traffic and running the appropriate countermeasures. SIEM tools alert of any unauthorized access into the network or suspicious network activities like multiple failed login attempts, etc.

It further stores all the data related to security threats and alerts in a centralized database that then security team members can access and mitigate effectively.
Endpoint security is becoming important for businesses with an increasing number of interconnected devices. According to Statista, there will be 30.9 billion interconnected digital units worldwide by 2025.
Your cybersecurity team can ensure IoT security through several practices. For example, implementing a domain name system (DNS) will stop malicious traffic from unauthorized sites to enter your interconnected network.
Similarly, maintaining an MDR (managed detection and response) will help your security personnel to timely detect vulnerabilities in and respond to any threats entering your network through any endpoint.
Your security team can also employ persistence detection. In persistent cyberattacks, attackers enter the vulnerable system and wait for the right opportunity to attack the network.
Security engineers look for such intrusions by regularly collecting and analyzing data related to the persistent processes.
Backup and Disaster Recovery:
A backup and disaster recovery solution is important to recover all the important business data in the case of unfortunate security incidents.
Your security team together with the business development team will map out a backup and disaster recovery strategy using the appropriate software solutions.
Your cybersecurity team can efficiently implement the above system and data security techniques and protocols using the right software tools. Some of these are listed below:
- Cisco Meraki for a unified thread management system.
- Cloudflare for implementing web application firewalls for cloud security.
- DUO for multi-factor authentication protocols.
- Backify for business data backup and recovery. It is a SaaS solution.
- Cisco Umbrella for DNS implementation and maintenance
- Huntress for persistence detection.
- Qualys for efficient security information and event management, etc.
Using Interoperable Technologies
While devising cybersecurity strategies, it is imperative to adopt a holistic approach and not think about your system and resources in silos.
One approach to creating such a holistic cybersecurity mesh is to introduce interoperability into your organization’s infrastructure.
Focus on integrating security analytics and associated data whether on the cloud or on-premises. This will allow the security team to efficiently analyze the data traffic and trigger the response security operations.
Decentralize Identification Management
As stated above, remote workforce and hybrid computing environments allow your users to access cloud-based applications from anywhere in the world if they have a stable internet connection.
A decentralized identity management system in place is compulsory to ensure that only authorized users can access and enter the system.
Authentication protocols, zero trust network security, identity proofing, etc., help in implementing a security system beyond your perimeter security in a cybersecurity mesh.
Centralize Security Policy Management
The IT infrastructure for almost every business is decentralized today with public, private, and hybrid cloud solutions. Multi-cloud may bring in more agility, scalability, etc., for your business, however, cloud services from different providers mean different resource access policies.
Cybersecurity mesh help here in implementing a robust approach to security controls. Consolidated dashboards help in adopting centralized policy management for the enterprise.
It focuses on introducing flexible security protocols and tools that help in separating policy and decision-making from the implementation and enforcement part.
Policy enforcement is centralized and separated from IT assets that help in uniform implementation across the processes and resources through dynamic runtime authorization services.
