Traditionally, a security operations center (SOC) is a physical facility where an organization performs information security activities. The SOC team analyzes and monitors the organization’s security systems. A SOC aims to protect businesses from security breaches by identifying, analyzing and responding to cybersecurity threats.
The SOC team consists of administrators, security analysts and security engineers. They work in collaboration with internal development and IT operations teams.
A SOC is a proven method to improve threat detection and incident response, reduce the potential for security breaches and help organizations respond appropriately in the event of an incident. The SOC team isolates unusual activity on servers, databases, networks, endpoints and applications, identifies and investigates security threats and responds to security incidents as they occur.
SOCs were once considered suitable only for very large organizations. But many small organizations today are building lightweight SOCs, such as hybrid SOCs that rely on a combination of part-time in-house staff and outsourced experts or virtual SOCs that function without physical facilities.
SOC Challenges
SOCs play a critical role in protecting an organization’s assets from cyber threats and ensuring the security and integrity of its networks and systems. However, SOCs can face a variety of challenges in their efforts to detect and respond to potential threats, including:
Alert Overload
Alert overload is a common challenge faced by SOCs. It occurs when the SOC team is inundated with too many security alerts, making it difficult to prioritize and effectively respond to them. This can be caused by a high volume of alerts, a lack of context or proper prioritization, limited visibility, or limited resources. To address the challenge of alert overload, SOC teams may implement strategies such as tuning security tools, implementing a triage process, utilizing automation, and increasing the size of the team.
Visibility Gaps
Visibility gaps refer to areas of an organization’s networks and systems that are not adequately monitored or protected by security tools and processes. These gaps create vulnerabilities that cyber threats can exploit, making it difficult for SOC teams to detect and respond to potential threats.
Visibility gaps may be caused by complex environments, limited resources, shadow IT, or misconfigured systems. To address visibility gaps, SOC teams may implement strategies such as implementing a security information and event management (SIEM) system, conducting regular assessments, implementing additional security controls, educating employees and ensuring that systems are properly configured.
Complex Investigations
Investigating cybersecurity threats can be a challenging task for SOC teams. It requires them to quickly and accurately identify the root cause of the threat and take appropriate action to contain and mitigate it. This can be difficult due to limited visibility, complex environments, a lack of context or limited resources.
To aid in the investigation process, SOC teams may use forensics tools to gather and analyze evidence related to potential security incidents. Common tools include network forensics tools, which allow the team to analyze network traffic and identify the source of a threat and digital forensics tools, which allow the team to examine devices and systems to identify evidence of an incident.
Slow Detection and Response Times
Slow detection and response times are a common challenge faced by security operations centers (SOCs). They can impact the organization’s mean-time-to-detection (MTTD) and mean-time-to-response (MTTR), which measure how long it takes the SOC team to detect and respond to potential security incidents.
A high MTTD and MTTR can have serious consequences for an organization, as it may allow a cybersecurity threat to remain active for an extended period of time, potentially causing significant damage.
What Is DevSecOps?
DevSecOps stands for development, security and operations. It is a new work process that involves integrating security practices into all DevOps processes. The DevSecOps mindset guides all technical experts equal access to security expertise.
DevSecOps moves security practices and enforcement early in the development process. This creates a culture where security is everyone’s responsibility, not just that of the security team.
Building security into every phase of the software delivery life cycle enables continuous integration and high development velocity with fewer security issues and lower compliance costs.
How DevSecOps Improves Security and Quality
Organizations using the DevSecOps model understand that security should not be an afterthought and should be a core part of the software development life cycle (SDLC).
DevSecOps collaboration is more difficult than DevOps because it requires achieving two seemingly contradictory goals simultaneously—expediting the delivery process while spending more time to make sure code is secure and free of bugs.
To implement DevSecOps without compromising product quality, organizations need to create a culture that deals with security-as-code, encouraging developers to consider the security aspects of their projects and automate security tasks. Organizations need to establish ongoing communication and collaboration between IT engineers, software developers and security teams.
How DevSecOps Processes Are Transforming the SOC
Traditionally, SOC processes were completely isolated from the rest of the organization. Developers would build systems, IT Ops run systems, and security protected them. Today, it is understood that merging these three functions into one organization that shares responsibility for security improves security and significantly increases operational efficiency.
SecOps was a second phase, in which operations and security teams became one organization. Security was shifted left, starting from early stages of IT requirements and system design, not at the end of the process.
SecOps had a major impact on organizations implementing DevOps. It paved the way for the third phase—broader collaboration between security, operations, and software development teams, known as DevSecOps. This moves security even further to the left, building security into the system from the first iteration of development.
DevSecOps can operate in parallel to a SOC. Here are some ways SOCs can modernize their processes, even if the SOC itself is a silo:
- Develop a decentralized SOC with DevOps members: Department members familiar with DevOps can help with incident response by gaining insight into IT systems and understanding vulnerabilities and threats to security personnel.
- Collaborate with threat hunters and DevOps teams: Instead of isolating threats and reporting them to management, threat hunters can communicate directly with development or operations teams to address key security vulnerabilities.
- Create a Center of Excellence: SOCs can work with development and operations teams to adopt security best practices and spread these positive results throughout the organization to promote DevSecOps practices.
- Allow the SOC to provide advice and guidance: Everyone involved in security should have easy access to the SOC and be able to work with the organization’s top security experts.
Conclusion
In conclusion, while DevSecOps can significantly impact how SOCs operate, it is unlikely to completely replace the SOC. DevSecOps emphasizes the integration of security practices and tools into the development process from the beginning, which can help to prevent security incidents from occurring in the first place. However, it is still important for organizations to have a dedicated team in place to monitor for and respond to potential security incidents.
The SOC will continue to play a critical role in protecting an organization’s assets from cybersecurity threats and ensuring the security and integrity of its networks and systems. By adopting DevSecOps practices, the SOC can improve the security and quality of the organization’s software applications, reduce the risk of security incidents and improve the efficiency of its operations. However, the SOC will remain a vital part of the organization’s overall security posture and will continue to evolve and adapt to new challenges as they arise.
