Quick Answer

A Cyber Security Analyst is responsible for monitoring, detecting, and responding to security threats that could impact an organisation’s digital assets. If you want to know “What does a Cyber Security Analyst actually do?”, the key tasks involve analysing security alerts, managing incidents, conducting vulnerability assessments, and ensuring compliance, often by using specialised security tools and collaborating with multiple teams.

Key Insights

Cyber Security Analysts play a hands-on, high-responsibility role in protecting organisational information by detecting and responding to security incidents. Their work directly affects a company’s operations, legal compliance, and reputation.

Core Responsibilities:

  • Network Security Monitoring: Continuously track traffic and logs for signs of intrusion.
    • Incident Detection & Response: Identify and act on threats immediately, often using SIEM (Security Information and Event Management) tools like Splunk or IBM QRadar.
    • Vulnerability Assessment: Regularly scan systems for weaknesses using tools such as Nessus.
    • Threat Analysis: Investigate and categorise threats, sometimes conducting root cause analysis.
    • Security Log Analysis: Review logs from various endpoints to spot anomalies.
    • Firewall and IDS/IPS Management: Configure, monitor and troubleshoot firewalls, and intrusion detection/prevention systems.
    • Compliance and Documentation: Ensure that security measures align with relevant standards like ISO 27001 and prepare formal reports for audits.
    • Collaboration: Frequently work with IT, legal, operations, and compliance teams for coordinated response.

    Commonly Used Tools:

    • Splunk (for security monitoring and SIEM)
    • Wireshark (for traffic analysis)
    • Nessus (for vulnerability scanning)
    • Palo Alto Networks platforms (for firewalls/IDS)
    • McAfee ePO (endpoint protection)
    • IBM QRadar (integrated SIEM and analytics)

    Relevant Certifications:

    • CompTIA Security+ (foundational security concepts)
    • Certified Ethical Hacker (CEH) (penetration testing and vulnerabilities)
    • CISSP (broad security knowledge, more senior)
    • Cisco Certified CyberOps Associate (operations-centric skills)

    Related Job Titles:

    • SOC Analyst
    • Information Security Analyst
    • IT Security Specialist
    • Threat Analyst

    Hiring Manager Perspective:
    Hiring managers at companies like Tech Mahindra often stress practical, hands-on experience and the ability to act quickly under pressure. Your ability to use SIEM tools independently, respond methodically to incidents, and communicate findings in clear reports are valued more than theoretical knowledge alone.

    Industry Reality:
    Expect shift work, especially in roles tied to Security Operations Centers (SOCs). The cybersecurity threat landscape keeps evolving, so ongoing self-learning and staying up to date with new tools, attacks, and compliance regulations is non-negotiable.

    Recruiter Reality

    Recruiters screen for candidates who can demonstrate actual experience with security monitoring and incident response—especially using the tools listed above. Strong documentation skills and clear examples of real-life incident handling make you stand out during interviews and on resumes.

    Best Practices

    Start with hands-on, actionable steps. Here are the best practices to succeed as a Cyber Security Analyst—especially if you want to progress at a reputed organisation, or through interviews and resume screening:

    1. Master Core Security Tools
    Gain real-world proficiency with SIEM solutions (Splunk, IBM QRadar), network analyzers (Wireshark), and vulnerability scanners (Nessus). Set up hands-on labs if possible.

    2. Strengthen Your Threat Analysis Process
    Always document every threat or incident with structured chronology: detection, analysis, containment, eradication, and recovery.

    3. Follow Incident Response Playbooks
    Develop procedural discipline: Use established frameworks (such as NIST or company-specific playbooks) to respond to incidents step by step.

    4. Prioritise Continuous Learning
    Regularly update your knowledge on the latest malware, phishing techniques, vulnerabilities, and compliance standards. Subscribing to threat intelligence feeds and security conferences/webinars is practical.

    5. Communicate Clearly
    Write clear incident reports and escalate issues effectively. Strong documentation is as critical as technical skills.

    6. Network with Professionals
    Use LinkedIn to follow cybersecurity communities, participate in Capture The Flag (CTF) competitions, and share security findings. Recruiters notice candidates who contribute to the professional ecosystem.

    7. Validate Skills with Certifications
    Add certifications like CompTIA Security+ or CEH if you lack direct SOC experience. Certifications can demonstrate core competency and commitment.

    TheEndorse Skill Gap Framework: Identify gaps by comparing job descriptions with your skills in these five domains:

    • SIEM operations
    • Threat and incident detection
    • Vulnerability scanning
    • Compliance/reporting
    • Communication and teamwork

    Address gaps through targeted learning, labs, or projects.

    Entity Bridge:
    Mastery of security tools and incident workflows directly improves your performance in interviews, enhances your resume visibility, and sets you up for career growth into roles like Senior Analyst or Security Consultant.

    Common Mistakes

    Many candidates underperform because they focus too much on theory and too little on practical, demonstrable skills. Here’s what to avoid:

    1. Ignoring Hands-on Practice
    Knowing definitions isn’t enough—employers want candidates who can use tools in real-time.

    2. Failing to Walk Through Incidents
    During interviews, not being able to explain step-by-step how you handled a security incident is a common red flag for hiring managers.

    3. Neglecting Teamwork and Documentation
    Security is a team activity. Not showing collaborative incident handling or thorough documentation weakens your application.

    4. Overlooking Company-Specific Tools
    Familiarise yourself with the specific brands and versions of security tools listed in the job description. If Tech Mahindra uses Splunk and Palo Alto, gain exposure to those environments.

    5. Focusing Only on Technical Skills
    Soft skills matter: poor communication, documentation, or stakeholder engagement can limit hiring chances or growth even for technically strong candidates.

    Recruiter Reality:
    Strong candidates bring in a portfolio of actual cases, SOC scenarios, or detailed reports that align with the tools and processes of the hiring organisation.

    Adjacency to Resume:
    Mistakes here translate to weak resumes—employers favour resumes that provide concrete details on tools, incidents, metrics, and your personal impact on risk reduction.
