Serverless Designs and the Evolving Role of Security Operations Centers (SOCs)

It's not news that the digital landscape is continually transforming, one of the trends that has gained substantial momentum over recent years is the adoption of serverless designs. These designs empower organisations to focus on code and functionality without the burden of infrastructure management and are now well established and embedded at many organisations.

An aspect of serverless design that is often overlooked is to what extent they reduce the traditional need for a Security Operations Center (SOC), this is a area of significant debate and somewhat controversial!

Serverless architectures introduce different security paradigms by abstracting underlying infrastructure, automating scaling, and enabling microservices-driven applications. They inherently come with certain security benefits, such as reduced attack surface and rapid response to security events.

However, it's important to acknowledge that security concerns will still persist, albeit in different forms.

SOCs play a vital role in bridging the gap between cutting-edge technology and cyber threats. They are the defenders of our digital realms, consistently monitoring, analysing, and responding to potential security breaches. While serverless designs minimise the need for managing server-level security, SOCs are typically still essential for:

• Threat Intelligence and Detection: SOCs possess the expertise to identify and mitigate advanced threats that might evade traditional security measures.
• Incident Response and Recovery: In the event of a breach, SOCs ensure a swift and measured response and guide the remediation process to minimise impact.
• Compliance and Regulations: Enterprises must adhere to industry regulations, and SOCs help ensure compliance in a dynamic technological landscape. It's not always a simple matter to assess or understand this, regardless of architecture.
• Continuous Improvement: SOCs engage in proactive security measures, learning from incidents to refine security protocols and strategies.

Embracing the future doesn't mean forsaking the wisdom of the past. It's not a question of "choosing" between serverless architecture and a SOC; it's about harmonising them to build a resilient security ecosystem.

It's also not to say that SOC capabilities can't be automated or supplemented to some extent with everything from SOAR to AI. There is still, (for the foreseeable future at least) a need for a human element to sufficiently protect business even in a mostly serverless setup.

By leveraging serverless architectures, a well run SOC can enhance its ability to detect and respond to security threats efficiently, enabling rapid incident response, improved scalability, and reduced operational overhead.

However, it's crucial to implement proper security practices for both the serverless functions themselves and the overall architecture to ensure the SOC's effectiveness and the protection of sensitive data.
