Hackers never rest, which is why it’s crucial for enterprise defenses to remain vigilant at all times. Threat actors often target businesses during off-hours when security personnel are scarce, leading to delays in response and remediation.
For instance, when retail giant Marks & Spencer faced a security incident over Easter weekend, they had to shut down their online operations, impacting a significant portion of their sales.
During off-hours and holidays, assembling an incident response team and implementing countermeasures can take time, giving attackers the opportunity to navigate through the network and cause damage before security teams can react.
While not every organization may have the resources to maintain a 24/7 in-house team, establishing a 24/7 Security Operations Center (SOC) is a proactive approach to defending against off-hours attacks. In the following sections, we will delve into the significance of continuous vigilance, the obstacles to achieving it, and a six-step strategy for 24/7 SOC success.
Significance and Challenges of a 24/7 SOC
A SOC is pivotal to an organization’s cybersecurity posture, responsible for identifying, investigating, and responding to potential threats round the clock, ensuring real-time threat mitigation. When coupled with automation, the efficacy of SOC operations increases, especially during off-peak hours and weekends.
However, running a 24/7 SOC is not without its complexities, necessitating a harmonious blend of established processes, sophisticated tools, and proficient personnel.
Strategic Planning and Embracing Automation
Where human resources fall short in keeping pace with evolving threats, Artificial Intelligence (AI) can play a pivotal role. By combining AI with established processes and skilled personnel, organizations can enhance efficiency through automated threat detection, resulting in expedited response times and bolstered security measures. Let’s delve into the development of robust processes and the integration of AI.
Six-Step Approach for Establishing a 24/7 SOC
The efficacy of a SOC hinges on implementing the following six key measures within your organization.
1. Tailoring a Foundation to Suit Your Organization
Establishing a resilient 24/7 SOC commences with defining a clear mission and scope aligned with overarching business objectives. A well-defined strategy aids in determining the requisite security coverage.
Given the recent surge in cyberattacks with severe repercussions, making a compelling case for 24/7 security monitoring is imperative, as budget allocations influence staffing decisions and tool integrations.
The optimal SOC model for your business will be contingent on its risk profile, regulatory compliance mandates, industry specifications, and available resources. The SOC’s objectives and scope should align with your business and industry requirements. For instance, a healthcare entity will prioritize safeguarding patient data to adhere to HIPAA regulations, whereas a retail establishment will focus on PCI DSS compliance.
Furthermore, whether opting for an internal, hybrid, or outsourced SOC model, leveraging AI within security operations can optimize your defense strategy, especially in the case of a hybrid SOC with AI-driven analysis.
2. Building a Competent Team and Providing Adequate Training
Organizations must assemble a proficient team capable of addressing security challenges. Hiring managers should seek a blend of novice analysts and experienced responders, fostering a collaborative environment.
SOC teams typically adhere to a three-tiered structure comprising Tier 1 analysts for alert triage, Tier 2 analysts handling investigation and response, and Tier 3 analysts overseeing strategic initiatives, advanced threat hunting, proactive detection, and AI tool optimization. In scenarios with constrained resources, a two-tier model can also prove effective, with Tier 1 managing triage and initial investigations, while Tier 2 focuses on in-depth analysis, response, and strategic functions, provided the right tools and processes are in place.
Prioritizing internal promotions is advantageous. Nurturing an internal talent pipeline and earmarking funds for continuous training and certification can empower team members to enhance their skills. For instance, team members can acquire proficiency in utilizing AI tools to address challenges posed by Security Information and Event Management (SIEM) solutions’ expensive log management and Security Orchestration, Automation, and Response (SOAR) platforms’ intricate configurations.
3. Implementing Thoughtful Shift Rotations to Mitigate Burnout
SOC teams are susceptible to quick burnout, necessitating sustainable shift rotations comprising 8- or 12-hour shifts. For instance, a SOC team can adopt a 4-on, 4-off schedule to maintain alertness, while multinational corporations can stagger shifts across various time zones to minimize fatigue risks.
It’s advisable to hire more analysts than initially deemed necessary, as many are compensated per shift, ensuring effective rotation, coverage during unexpected absences, and reduced strain on core team members. This approach offers flexibility without overburdening the staff.
Security practitioners thrive on diversity and challenge, necessitating periodic rotation of responsibilities such as alert triage, playbook reviews, and threat hunting.
Establishing clear handoff protocols to facilitate seamless transitions is crucial. Encouraging knowledge sharing among teams nurtures a collaborative atmosphere. Automation can alleviate the team’s workload, particularly in automating repetitive tasks like log analysis or phishing assessment, aiding in talent retention.
Wellness programs play a pivotal role in enhancing team morale. Promoting work-life balance, establishing channels for anonymous feedback, scheduling downtime, and endorsing regular breaks are essential practices. Stressing the importance of adhering to scheduled breaks unless during an active incident is crucial.
Recognizing and rewarding team members for their contributions is paramount, bolstering job satisfaction and aiding in talent retention.
4. Selecting the Appropriate Tools
Thoroughly evaluating and opting for AI-driven security tools that align with specific business requirements and security prerequisites is imperative. Factors such as cost and complexity should be taken into account before finalizing a tool selection.
For instance, certain Security Information and Event Management (SIEM) solutions like Splunk encounter scalability issues and high log management costs, posing challenges in multi-cloud environments. Similarly, Elastic’s Attack Discovery tool is prone to generating numerous false positives, necessitating manual validation by analysts.
While AI-powered tools reduce manual efforts to a great extent, they necessitate significant setup, rule refinement, data integration, and dashboard customization. Some features might mandate analysts to configure data sources and interpret outcomes. Several SOC tools are static, featuring pre-trained models tailored for a handful of use cases.
Existing Security Orchestration, Automation, and Response (SOAR) solutions demand extensive configuration and maintenance, with static playbooks incapable of dynamically adapting to emerging threats.

5. Fostering a Culture of Continuous Learning
Security leadership should encourage post-incident analyses without assigning blame. Each security event offers valuable insights, which should be documented in a knowledge repository.
Promoting continuous learning is instrumental in staying ahead of threats. Providing seamless access to research materials and training resources, sponsoring certifications like GIAC Intrusion Analyst certification (GCIA) and Offensive Security Certified Professional (OSCP), and fostering a culture of knowledge sharing among team members are essential practices.
Regular threat briefings, security drills such as red team versus blue team simulations to identify process gaps, and enhancing coordination with Legal, Public Relations, and IT teams are pivotal in honing response capabilities. Tabletop exercises for executives to assess decision-making under pressure are also beneficial.
6. Governance, Metrics, and Reporting
Defining success metrics encompassing Mean Time to Detect (MTTD), Mean Time to Respond (MTTR), AI accuracy, and false positive rates is crucial. Swift detection limits the extent of damage, while rapid response mitigates the repercussions of an incident. Accurate AI implementations instill trust in automation, whereas low false positives reduce the analyst burden.
Ensuring equitable distribution of workload and alert volume across SOC shifts promotes balance and reduces burnout risks. Monitoring incident statistics alone is insufficient; it is essential to track employee well-being continuously, as a healthy SOC team correlates with high morale and consistent performance.
Real-time dashboards and monthly reviews are indispensable. Visual representations, in-depth analyses for team leads, and comprehensive insights for SOC managers and Tier 3 analysts are vital for optimizing tools, aligning compliance with business risks, and monitoring team well-being.
