Companies rely on security operations centers (SOCs) to counter cyberattacks. According to Sylvain Defix of NTT Security, the outsourcing of these centers reduces the cost of implementation and operation but also ensures a high level of expertise and the necessary skills.
The outsourcing of its cybersecurity center arises in terms of investment, operating costs and maintaining the necessary skills.
Security incidents are multiplying worryingly. The creativity of cybercriminals seems unlimited. Ever faster and more sophisticated threats to information systems (IS) companies: blocking production or access to vital information for the conduct of the activity, theft of personal or industrial data, loss of customer base…
Protecting yourself from these risks requires an increasingly complex response. The solution must combine tools, both software and hardware, processes and human skills. Everything must be available and operational 24 hours a day. But few companies have the means to develop, operate and especially to maintain such a solution.
The Security Operations Center (SOC) provides an effective response to this problem. It plays both a preventive role, detecting security breaches of the IS before an attack is conducted, but also reactive, facilitating the management of incidents and minimizing their impact on the company. It must be able to detect an attack in progress and block it quickly. A SOC must also anticipate new attacks and respond to them thanks to technologies of artificial intelligence and machine learning that are increasingly used in the field of cybersecurity.
To fully play this role, in addition to addressing business or technology changes, a SOC, by definition, must be as agile as threats and attack methods. For non-cybersecurity companies, only an outsourced SOC can ensure scalability and efficiency.
The added value of outsourcing is the same for a SOC as for the other components of the IS. This is the pooling of resources, which entails a reduction in the cost of implementation and operation but also the maintenance of high-level expertise and the necessary skills. This reduction in costs can be considerable. Indeed, for 24/7 monitoring and analysis (outside control management) via an outsourced SOC, it is necessary to count a budget between 350k € to 810k € while a internalisation of the SOC costs between 1060k € and 1870k € by including the development and maintenance of the platform but not technological costs.
On the other hand, a benefit of outsourcing is specific to cybersecurity: agility. It offers high availability 24/7 at no additional cost and a permanent update of threat intelligence. This watch on threats and incidents is difficult to achieve by a single company. A SOC operator consolidates many sources of intelligence, public sources, but also internal sources. As Internet backbone managers, these SOC operators analyze the global Internet flow in real time and integrate that data into their global threat intelligence center. Its dedicated analysts (by experience, about fifteen people per SOC) are thus able to quickly detect security incidents, to qualify them and to help clients protect themselves. Because the hunt and the treatment of the attacks have become a trade in itself, and it is this trade that exercises a operator of SOC.
