Cybersecurity Mesh: more efficient risk management

Cybersecurity Mesh: more efficient risk management 

While technological advances bring innovation and convenience, they also open the door to constantly evolving cyber threats. In today's information security landscape, the need to adapt and innovate has never been more imperative. 

According to a recent survey by Gartner, global investments in information security are expected to reach an impressive US$ 187 billion by the end of 2023 - an increase of 11.1% compared to the previous year. This growth signals a growing awareness of the importance of cybersecurity. However, Gartner also reinforces that, as threats diversify and intensify, security leaders will need to update their strategies and knowledge. 

Since 1996, ISH has been a beacon of innovation and reliability in the sector, evolving from integrators to leaders in managed security services. In light of this, ISH has developed a maturity framework for clients, structured into five levels - Govern, Know, Strengthen, Manage and Monitor.  

This model not only guides clients through a process of strengthening their cybersecurity, but also reflects our holistic approach, which understands security as a continuous cycle of improvements and adaptations. The result of this new construction model, based on the information security maturity journey, is the Cybersecurity Mesh. In this article, we will explore and better understand this concept. 

What is Mesh architecture? 

Once the needs of the client's environment have been identified through an analysis of their security journey, the service model proposed by Mesh Architecture is built by integrating strategic services such as consultancy, vulnerability management, managed security services, threat intelligence and governance. 

 This strategy is developed in such a way as to allow complex and decentralized environments to be managed, due to its adaptability to the client's demands. In this way, it is possible to reinforce cyber security in an agile and efficient manner, skills which are fundamental to keeping the technological environment safer. 

The strategic Mesh Architecture model is built through the following steps: 

  1. Analysis and recognition of the environment 

In this phase, the company's scenario is fully recognized. It analyzes how all users access devices and data, what regulations they are subject to, their privacy management and that of third parties. Assets and vulnerabilities are also mapped. The analysis phase is fundamental so that resources are not wasted on surfaces with low risk for the business.  

  1. Creation of the Strategic Information Security Plan 

After analyzing and understanding the level of exposure to vulnerabilities that the client is subject to, whether in assets, compliance or through third parties, the creation of the strategic information security plan begins. All the assets and attack surfaces are mapped, and the appropriate protections are assigned, i.e. the security strategy is developed to cover all the mapped attack surfaces.  

  1. Building the Mesh Architecture model  

  Once all the analysis and planning has been carried out, now is the time to apply the strategic information security plan and build the architecture with the necessary solutions and services. To build an effective information security architecture, it is necessary to pay attention to the following phases and develop a security procedure for each one: 

  1. Managing cyber exposure levels 
  2. Telemetry of controls in the environment 
  3. Posture management and cyber intelligence 
  4. Event monitoring
  5. Incident triage
  6. Incident response
  7. Continuous improvement

Once the entire security management plan has been implemented, systematic efforts must be made to improve the processes that are being carried out. This improvement is achieved through the continuous work of creating simulations of intrusions, automating processes, documenting and analyzing indicators, enriching data with the use of cyber intelligence, improving the incident response plan, among other actions.  

Benefits of implementing CSMA architecture 

The implementation of the CSMA architecture represents a breakthrough in the security approach, bringing many benefits to companies. Some of these include: 

  • Preventing Data Breaches and Leaks: With its ability to offer additional protection, mesh architecture is indispensable in preventing threats and data breaches. 
  • Effective security environment: Cybersecurity Mesh's adaptability makes it indispensable for companies seeking digital transformation and providing a consolidated security environment. 
  • Optimizing Security Investment: By optimizing processes and promoting collaboration between control points, mesh architecture maximizes the return on security investment, ensuring that every penny spent counts in the fight against cyber threats. 
  • Unified visibility: Consolidating information from various security solutions into a single, coherent view is vital for making informed decisions about risks. 

Cybersecurity Mesh: the future of cybersecurity risk management  

The CSMA architecture implementation strategy allows for flexibility and customization, making vulnerability management more effective and adaptable to different needs. For CISOs (Chief Information Security Officers), this translates into a revolution in the way risks are managed, providing resilience, agility and scalability. By allowing different solutions to be orchestrated in a single structure, a unified and coherent vision is created

For the business world, it is vital to stay ahead of the curve by adopting and implementing best practices to guarantee the integrity, confidentiality and availability of data and resources.
