What is SSE?

Secure Service Edge (SSE) is a network security framework that primarily focuses on enhancing security for accessing cloud-based services and applications. It revolves around implementing robust security measures at the network's edge to safeguard data and users when they connect to cloud resources. SSE prioritises strengthening security, especially for remote and mobile users accessing cloud applications.

SSE seamlessly blends various networking and security functions into a unified, cloud-based architecture. Its core aim is to empower organisations with enhanced visibility, control, and protection over their networks, data, applications, and users while simplifying IT operations.

What does SSE include?

  • Secure Web Gateway (SWG): Shields and monitors web traffic to defend against threats like malware, phishing, and data breaches.
  • Cloud Access Security Broker (CASB): Provides visibility and control over cloud-based applications and services, ensuring compliance with corporate security policies.
  • Firewall-as-a-Service (FWaaS): Delivers cloud-based firewall capabilities, protecting organisations from network-based threats.
  • Zero Trust Network Access (ZTNA): Enforces identity-based access control to applications and resources, permitting entry solely to authenticated and authorised users and devices.
  • And more

By bringing these technologies together under a single architecture, SSE helps organisations achieve a more comprehensive and streamlined approach to security. This becomes increasingly vital in today's landscape, where remote work, widespread cloud adoption, and the prevalent use of mobile devices have led to a more intricate and dispersed IT environment.

What are the technical components of an SSE solution?

A Secure Services Edge solution combines key technical components to deliver secure and optimised network connectivity. While specific implementations may differ, here are common components you'll find in an SSE solution:

1. Edge devices/gateways

These are network devices deployed at the edge of the network, such as branch offices, remote sites, or cloud service PoPs. They serve as the entry point for network traffic and provide connectivity and security services at the edge.

2. Software-Defined Networking (SDN)

SDN technology enables centralised control and management of network resources. It allows for dynamic configuration, optimisation, and segmentation of network traffic, enhancing security and performance.

3. Network virtualisation

Network virtualisation separates the logical network infrastructure from the physical hardware, allowing for greater flexibility and scalability. It enables the creation of virtual networks, virtual segments, and virtualised security services, facilitating secure and isolated connectivity.

4. Security services

SSE incorporates various security services to protect network traffic and data. These may include:

  1. Firewall: Controls and filters network traffic based on predefined security policies, preventing unauthorised access and protecting against threats.
  2. Secure Web Gateways (SWG): Scans web traffic for malicious content, enforces web usage policies and protects against web-based threats.
  3. Intrusion Detection and Prevention System (IDPS): Monitors network traffic for suspicious activity or known attack patterns, alerting or blocking potential threats.
  4. Data Loss Prevention (DLP): Identifies and prevents unauthorised transmission or leakage of sensitive data, such as personally identifiable information (PII) or intellectual property.
  5. Secure remote access: Enables secure connectivity for remote users, often utilising VPN (Virtual Private Network) technologies to encrypt communications and authenticate users.

5. Cloud-native infrastructure

SSE leverages cloud-native technologies and services, such as microservices architecture, containerisation, and orchestration platforms (e.g., Kubernetes). These technologies enable scalability, agility, and flexibility in deploying and managing network and security functions.

6. Centralised management and orchestration

A centralised management and orchestration platform is crucial for configuring, monitoring, and managing the SSE solution. It provides a unified interface to define policies, monitor network traffic, and enforce security rules across the distributed network environment.

7. Analytics and intelligence

SSE solutions often incorporate analytics and intelligence capabilities to gain insights into network performance, security threats, and user behaviour. These insights can be used for proactive security measures, capacity planning, and optimisation.

Keep in mind that specific components may vary among SSE solutions and vendors. The core objective remains consistent: integrating networking and security functions at the network's edge to offer secure and efficient network connectivity in distributed environments.

What is the "edge-centric" approach to SSE?

The "edge-centric" approach in SSE refers to prioritising the deployment of network and security functions closer to the network's edge. Traditional network architectures often backhaul most traffic to centralised data centres or headquarters for security and policy enforcement. However, this can introduce latency and security challenges, especially with the growing use of cloud services and remote work.

The edge-centric SSE approach addresses these issues by distributing network and security functions to the edge, nearer to users and devices. This move places security and networking capabilities closer to the access point, reducing the need for traffic to travel long distances, and resulting in better performance.

By deploying security and networking functions at various points within the network infrastructure, such as branch offices, remote sites, cloud service PoPs, or user devices, organisations can achieve optimised and secure connectivity, regardless of user location, device, or application.

This shift toward the network edge minimises latency, enhances user experience, and bolsters security. It aligns with the concept of edge computing, which brings computing closer to data sources or end-users for reduced latency and improved real-time processing.

Once upon a time

Think of SSE as a virtual fortress

Once upon a time in the world of digital innovation, there was a company called Techtronics Inc.* They were renowned for their cutting-edge technology solutions and relied heavily on the cloud to run their business efficiently. However, as they grew, so did their cybersecurity concerns.

One day, the CEO, Sarah*, gathered her team to address these growing security challenges. Their existing approach of securing the network perimeter just wasn't cutting it anymore. They needed something more dynamic and robust.

Enter SSE, or Secure Service Edge, a revolutionary concept in the world of network security. It was like a shield that could adapt to the changing landscape of the digital world.

Sarah explained SSE to her team as follows: "Think of it as a virtual fortress that surrounds our entire digital infrastructure. It's not just about building walls; it's about creating an intelligent defence system. SSE combines the power of edge computing with advanced security functions to protect our data, our applications, and our users."

As they implemented SSE, the benefits became apparent. Their employees could securely access cloud-based services and applications from anywhere, whether they were working from home, a coffee shop, or the office. It was like having a personal bodyguard for each data transaction, ensuring it reached its destination safely.

With SSE, Techtronics Inc. could also optimise their network traffic, reducing latency and boosting overall performance. It was as if they had installed a smart traffic control system that made sure their data took the fastest and safest route to its destination.

As the story goes, Techtronics Inc. continued to thrive, all thanks to the powerful concept of Secure Service Edge. They had not only strengthened their defences but had also embraced the flexibility and agility needed in the ever-evolving world of technology. And so, their digital journey continued, safer and more efficient than ever before.
