Building an SOC is a natural progression in an organisation’s cyber security journey. However, it can be daunting for a small or mid-sized organisation.
Today, we’ll look at five reasons why an SME might consider building an SOC, plus a common alternative that could provide your organisation with all the same benefits at a fraction of the cost. But first…
Gartner defines a SOC as:
“A security operations centre (SOC) can be defined as a team, often operating in shifts around the clock, and a facility dedicated to and organised to prevent, detect, assess and respond to cyber security threats and incidents, and to fulfil and assess regulatory compliance.”
Not every SOC has the same responsibilities. Key cyber security functions are usually separated into specialised teams in larger organisations with more resources. For example:
However, the SOC is typically responsible for most security tasks for smaller organisations. These tasks broadly fall within five essential functions:
In simple terms, a SOC is a centralised security team that monitors and enhances an organisation’s security profile and detects, responds to, and recovers from security incidents
Building an SOC from scratch can seem like a big step, particularly if your organisation already has some security personnel, perhaps scattered across various IT teams. After all, why invest resources in building a centralised SOC when your current setup is “doing the job?”
While no doubt building a SOC requires a significant investment of time and resources, there are (at least) five clear benefits—even for a smaller organisation:
In a pre-SOC organisation, security personnel are usually limited to working during business hours. Sadly, cybercriminals have no such constraints. Many criminal groups are located in other time zones, and it’s also common practice to intentionally time cyberattacks to fall out of hours, as it limits the victim organisation’s opportunity to respond to and resolve the attack quickly.
Security personnel typically work shifts in an SOC to ensure complete 24/7/365 coverage. This significantly reduces cyber risk, allowing analysts to uncover malicious activity in real time and begin response activities.
Today’s IT environments are hugely complex. Digital transformation initiatives, cloud migrations, and new technologies such as IoT devices have led to business networks that are difficult to understand, let alone monitor for security threats.
This is precisely what a centralised SOC is for. A well-designed and equipped SOC can continuously monitor even the largest, most complex network environments, quickly identifying suspicious or malicious activity for further investigation.
When security personnel are scattered across various teams and locations—as is common in SMEs—it can be difficult for them to collaborate effectively. In a centralised SOC, security personnel are typically based in a single location, making it easy to communicate and cooperate as needed.
SOCs also have more established processes and procedures for security tasks and functions. This ensures greater consistency in security operations, leading to reduced cyber risk.
According to IBM’s Cost of a Data Breach report, it takes organisations 287 days to identify and contain a data breach. This is far too long. The fallout from a breach can be substantially reduced if it is promptly identified and contained, but this is tough when security resources aren’t well managed.
In a smaller organisation, detecting, responding to, and recovering from cyber incidents is the number one security priority—and a centralised SOC team will always outperform disparate, disconnected security personnel.
Cyber security always includes a strong reactive element—but that’s not all it should be.
A SOC’s most critical role is identifying tools, policies, and procedures the organisation can implement to block common threats. This typically involves a combination of security solutions, secure system/network design, and ongoing system hardening, which can dramatically reduce cyber risk.
Building a centralised SOC has clear benefits for SMEs… but there’s still a problem. There are several problems. Most notably:
So, what’s the alternative?
Rather than building an effective SOC in-house, many SMEs prefer to outsource their security operations needs to a managed SOC provider. This allows them to achieve the cyber security coverage they require at a significantly lower overall cost, without the ongoing challenge of hiring and retaining skilled security professionals.
Other benefits of outsourcing include:
Managed SOC providers have the luxury of scale, allowing them to retain highly experienced security practitioners with a wide range of specialist skills. This typically enables them to identify and resolve security incidents more quickly and effectively than an in-house SOC, reducing their impact.
A SOC should provide coverage 24x7x365, which is impossible for an in-house team due to staffing and budget constraints. A managed SOC provider can ensure continuous coverage while splitting coverage among customers, making it a far more affordable way to achieve “always-on” coverage.
Coverage for success can be expensive and not a one-off cost. The threat landscape evolves quickly, and SOC teams need a toolset that keeps pace. A reputable managed SOC provider will always ensure its team is equipped with best-in-class security tools and resources, protecting customers against the latest threats and attack vectors.
One of the biggest challenges for security teams of all disciplines is reacting quickly to business needs—particularly if those needs include significant changes in scale. No business wants to be held back by its security team, but equally, it can’t be left unprotected during expansion. Unlike in-house teams, which can take months to adapt, an outsourced SOC can scale up or down at a moment’s notice to meet business needs.
