30in30 – Post 5 – SASE: The Future of Network Security and Remote Work

Welcome to the 30-in-30 blog campaign! I’m excited to launch this initiative, which involves publishing a brand new blog post every single day for the next 30 days. I will not mince words about this. It is hard to keep it up, stay engaging, relevant and interactive. More about this campaign  is at the end of this article.

In the wake of the COVID-19 pandemic, remote work has become the new normal for many organizations, and this trend is expected to continue in the future. While remote work provides many benefits, it also creates new cybersecurity challenges, as employees work from outside the traditional security perimeter. In response, a new approach to network security has emerged, known as Secure Access Service Edge (SASE).

SASE is an emerging security model that combines network security functions, such as Firewall as a Service (FWaaS), Secure Web Gateway (SWG), and Cloud Access Security Broker (CASB), into a unified cloud-delivered service. SASE provides a more comprehensive and holistic approach to network security, and it is specifically designed to meet the needs of remote work and cloud computing.

SASE is an important development in the world of cybersecurity, as it addresses the challenges posed by the changing nature of work and the rise of cloud computing. However, like any new technology, it also comes with its own set of risks and challenges. In this article, we will explore the benefits and risks of SASE and provide guidance on how organizations can adopt this new approach to network security.

The Benefits of SASE

SASE provides many benefits to organizations that are looking to improve their network security posture. Here are some of the key benefits of SASE:

  1. Increased Security: SASE combines several security functions into a single, cloud-based platform, making it easier to manage and secure remote access to resources. With SASE, organizations can enforce security policies across all endpoints and users, regardless of their location.
  2. Improved Performance: By leveraging cloud-based security and networking technologies, SASE can improve network performance and reduce latency. This is especially important for remote workers who rely on cloud-based applications and services.
  3. Simplified Management: SASE provides a centralized platform for managing all security and networking functions, which reduces complexity and simplifies management. This can help organizations streamline their IT operations and reduce costs.
  4. Scalability: SASE is designed to be highly scalable, making it easy for organizations to add or remove users, services, and locations as needed. This makes it an ideal solution for organizations that need to rapidly scale their IT infrastructure to accommodate growth or changing business needs.
  5. Cost-Effective: SASE can help organizations reduce their IT costs by consolidating multiple security and networking functions into a single platform. This can also help reduce the need for expensive hardware and software solutions, as well as the cost of managing and maintaining these systems.

The Risks of SASE

While SASE provides many benefits, it also comes with its own set of risks and challenges. Here are some of the key risks of SASE:

  1. Complexity: SASE is a complex technology, and it can be challenging for organizations to implement and manage.
  2. Dependence on the cloud: SASE is a cloud-delivered service, which means that organizations are dependent on their cloud service providers for network security.
  3. Compliance: SASE may pose compliance challenges for organizations that are subject to industry-specific regulations, such as HIPAA or PCI DSS.
  4. Vendor lock-in: SASE requires organizations to rely on a single vendor for their network security needs, which may limit their flexibility and ability to switch providers.

How to Adopt SASE

Adopting SASE is a complex process, but it is essential for organizations that want to better protect their assets, data, and systems. Here are some steps that organizations can take to adopt SASE:

  1. Conduct a risk assessment: Before adopting SASE, organizations should conduct a risk assessment to identify their security needs and evaluate the risks and benefits of SASE.
  2. Develop a roadmap: Once the risk assessment is complete, organizations should develop a roadmap for implementing SASE. This roadmap should include a timeline, budget, and a list of required resources.
  3. Define the who and the what: Create an asset inventory across your entire environment. Then define who needs access to what resources based on roles and responsibilities.
  4. Choose a vendor: Organizations should choose a vendor that meets their security needs and has a proven track record in delivering SASE solutions.
  5. Implement SASE: Once a vendor has been selected, organizations can begin implementing SASE. This process typically involves configuring and deploying the various security services, such as FWaaS, SWG, and CASB.
  6. Monitor and evaluate: After SASE has been implemented, organizations should monitor and evaluate its effectiveness

How to Implement SASE

Implementing SASE requires careful planning and execution to ensure a smooth transition and minimize disruption to the business. Here are some key steps to follow when implementing SASE:

  1. Assess Your Current Security and Networking Infrastructure: Before implementing SASE, it’s important to assess your current security and networking infrastructure to identify potential gaps and areas of improvement. This will help you determine which SASE features and capabilities are most important for your organization.
  2. Develop a Migration Plan: Once you have identified the key areas for improvement, you can develop a migration plan that outlines the steps required to transition to SASE. This should include timelines, resources, and a plan for testing and validation.
  3. Select a SASE Provider: There are several SASE providers in the market, each with their own strengths and weaknesses. It’s important to carefully evaluate each provider based on your specific needs and requirements. Factors to consider include security features, network performance, scalability, and cost.
  4. Pilot Test the Solution: Before fully implementing SASE, it’s important to pilot test the solution to ensure it meets your requirements and works as expected. This should include testing all security and networking features, as well as performance and scalability.
  5. Roll Out the Solution: Once you have validated the solution through pilot testing, you can begin rolling it out across your organization. This should include training and education for end-users, as well as ongoing monitoring and maintenance to ensure the solution continues to meet your needs.
