SOC is a structure made of technological and human resources, processes, procedures and certifications, whose objective is to develop and guarantee a methodology for Security Incident Response. This methodology will manage, control, monitor and report the Security Incidents that an organization may have.
From the description, we immediately realize that the need for a SOC is real and must be adressed, but let's understand why is it so necessary:
Continuous Monitoring: Cyberattacks have no breaks or pauses and can happen at any time, without any regard for the operation of an organization. Usually, they happen during after-work hours or weekends, to increase the odds of success.The continuous, round-the-clock monitoring that a SOC provides is a key defense in these situations.
Centralized Management and Visibility: Organizations' networks are increasing their level of complexity, both through the acceleration of digital transformation that has happened in recent years and through the recent adoption to remote work. In order to protect a network that is becoming increasingly diverse, organizations must have an integrated solution that enables network visibility. Through the set of tools it integrates, SOC is an effective answer, and allows organizations to have a visibility of their infrastructure, so they can manage it in a more efficient and defensive when attacks take place.
Reduced Cybersecurity Costs: Maintaining strong and effective cybersecurity is a high expense, both in terms of human and technology resources. An external SOC reduces these costs, because they aren’t the responsibility of a single department and are inherent to the organization, eliminating expenses that are usually associated to duplication and redundancy. In addition, an effective SOC promotes long-term savings because it prevents attacks that can financially harm the organization - a successful ransomware attack will generate high costs in terms of system downtime and recovery. A robust and efficient SOC blocks the cyberattack before the damage occurs, which in itself is a return on investment.
Increased level of collaboration within the organization: Collaboration between teams is essential to effectively detect and respond to security incidents. When an organization doesn’t develop or communicate which are the processes to identify, notify and respond to a cybersecurity incident, there will occur delays and behaviors that will increase the odds of the attack’s success, making its eradication more difficult. With an external SOC, all the resources will be centralized into a single team that will support the organization as a whole. The SOC will support collaboration between employees and will make it easier to respond to the organization's cybersecurity needs (such as 24/7 network monitoring and immediate response to potential security incidents).
The hiring of a SOC will enable a dynamic and permanent security that acts as a true center for analysis, monitoring, prevention and immediate correction of any incident that may be directed at the organization.
