Introduction
What is a Security Operations Center (SOC)?
A Security Operations Center (SOC) is a centralised function that serves as the nerve centre for an organisation’s security operations. The SOC is responsible for monitoring, detecting, analysing, and responding to ssecurity incidents in realtime to protect the organisation’s data, systems, and networks. It is staffed with skilled security professionals and equipped with advanced tools and technologies to proactively identify potential threats and mitigate risks.
Key SOC Functions:
Continuous monitoring of network traffic and system logs.
Incident detection and response.
Threat intelligence collection and analysis.
Vulnerability assessment and management.
Collaboration with other IT and security teams.
Reporting on security posture and incidents.
SOCs operate 24/7 in most cases to ensure round-the-clock protection against evolving cyber threats, making them an essential component of modern security strategies.
Required Skillset of a SOC Analyst
A SOC Analyst plays a critical role in detecting security threats. To excel in this role, individuals must possess a combination of technical expertise, analytical thinking, and communication skills.
Core Technical Skills:
Network Security:
Understanding of TCP/IP, DNS, firewalls, and VPNs.
Familiarity with network intrusion detection and prevention systems (IDS/IPS).
Endpoint Security:
Knowledge of endpoint detection and response (EDR) tools.
Proficiency in analysing system logs and monitoring endpoint activities.
Threat Analysis:
Understanding the MITRE ATT&CK framework and other frameworks.
Ability to analyse malware, phishing attempts, and other threats.
SIEM Tools:
Proficiency in Security Information and Event Management (SIEM) tools like Splunk, Sentinel, or QRadar.
Incident Response:
Skills in triaging, investigating, and remediating security incidents.
Experience with digital forensics tools and techniques.
Scripting and Automation:
Familiarity with Python, PowerShell, or Bash to automate routine tasks.
Soft Skills:
Critical Thinking and Problem-Solving: Ability to quickly assess and respond to evolving threats.
Communication Skills: Clear articulation of technical findings to non-technical stakeholders.
Teamwork: Collaboration with other SOC analysts and IT teams.
Attention to Detail: Meticulous review of logs and alerts to identify anomalies.
SOC Analyst Daily Tasks
SOC Analysts are at the forefront of defending an organisation against cyber threats. Their day-to-day responsibilities include:
Monitoring and Alert Management:
Continuously monitoring security dashboards and alerts.
Prioritising and triaging alerts based on severity.
Incident Investigation:
Conducting root-cause analysis of security incidents.
Identifying compromised systems and affected data.
Threat Hunting:
Proactively searching for indicators of compromise (IoCs).
Utilising threat intelligence to uncover potential vulnerabilities.
Reporting and Documentation:
Industry-recognised records of incidents and response actions.
Generating periodic reports on security trends and posture.
Collaboration:
Coordinating with IT teams to resolve vulnerabilities.
Sharing insights with threat intelligence and incident response teams.
Tool Maintenance:
Ensuring SIEM, IDS/IPS, and other security tools are operational and updated.
Fine-tuning alert thresholds to reduce false positives.

Path to Becoming a SOC Analyst
Step 1: Build Foundational Knowledge
Pursue a degree in Computer Science, security, or a related field; however, a degree is not required.
Gain a strong understanding of networking, operating systems, and security principles.
Step 2: Gain Practical Experience
Intern with IT departments or security teams to gain hands-on experience.
Participate in security bootcamps or capture-the-flag (CTF) competitions.
Create a home lab for dedicated practice
Step 3: Obtain Relevant Certifications
Begin with entry-level certifications like Security+ and gradually progress to advanced certifications.
Step 4: Apply for Entry-Level Roles
Look for roles such as SOC Analyst Tier 1, IT Support Specialist, or Network Administrator.
Focus on gaining experience in core security skills, including log analysis, incident response, SIEM and EDR tools.
Step 5: Continue Professional Development
Stay updated on emerging cyber threats and technologies.
Pursue higher-level certifications and specialise in areas like incident response, threat hunting or digital forensics.
While the above recommendation is unlikely to be a fit for everyone, in general, by following the path, aspiring professionals can successfully embark on a rewarding career as a SOC Analyst, playing a pivotal role in safeguarding organisations against cyber threats.
