Ms Rachel Williams
Chief Information Security Officer
Commonwealth Bank of Australia
Level 18, 201 Sussex Street
Sydney, NSW 2000
Dear Ms Williams,
When I discovered that Commonwealth Bank is expanding your Security Operations Centre to strengthen threat detection and incident response capabilities, I recognized this was precisely the opportunity I’ve been working toward. As someone who monitored security infrastructure for ANZ’s enterprise environment—detecting and responding to 2,400+ security incidents annually, reducing mean time to detect from 6 hours to 45 minutes through improved SIEM rules, and identifying a sophisticated phishing campaign that prevented potential $2.8M fraud—I’m thrilled at the prospect of combining technical expertise and analytical thinking for your comprehensive security program.
Over the past four years as a Security Analyst working throughout Sydney’s financial services and technology sectors, I’ve repeatedly delivered results that match perfectly with your needs. I’ve monitored security events using SIEM platforms including Splunk and QRadar, investigated security incidents conducting forensic analysis and root cause determination, performed vulnerability assessments and penetration testing identifying critical risks, implemented security controls and remediation strategies reducing attack surface, collaborated with IT teams remediating vulnerabilities and hardening systems, and developed security documentation including incident response procedures and threat intelligence reports. My background spanning threat detection, incident response, and vulnerability management has shown me that exceptional security analysis merges technical capability with strategic threat intelligence—precisely what you require for protecting critical financial infrastructure.
What really attracts me to Commonwealth Bank is your investment in cutting-edge security technology and commitment to threat-hunting programs. I hold a Bachelor of Information Technology (Cyber Security) from University of Technology Sydney, Security+ and CEH (Certified Ethical Hacker) certifications, and strong proficiency in security tools including SIEM platforms, IDS/IPS systems, endpoint detection and response, and security orchestration platforms. I’ve completed professional development in threat intelligence analysis, malware reverse engineering, and incident response frameworks. I’m convinced that security analysts aren’t merely alert responders—we’re cyber defenders who hunt emerging threats, protect business operations from evolving attacks, and strengthen security posture through continuous improvement and intelligence-driven defense.
I’d welcome the chance to discuss how my proven ability to detect threats and respond effectively to security incidents can enhance Commonwealth Bank’s security operations. Thank you for reviewing my application, and I look forward to connecting with you soon.
Kind regards,
Marcus Chen

What to Include in a Security Analyst Cover Letter (Australia)
Your Security Analyst cover letter needs to follow a technical yet accessible structure that showcases both cybersecurity expertise and analytical capability:
- Contact Details
- Salutation (Dear Hiring Manager or name)
- Opening paragraph – your hook and intent
- Middle – why you’re the best fit (skills + experience)
- Closing – call to action + sign off
Right vs Wrong Example
Right Opening: “When Atlassian announced your SOC expansion requiring 24/7 threat monitoring across global cloud infrastructure serving millions of users, I instantly recognized where my background monitoring enterprise security environments—analyzing 15,000+ daily security events, identifying and mitigating 3 critical zero-day vulnerabilities before exploitation, and reducing false positive rates by 62% through tuned detection rules—could strengthen your security posture while supporting your rapid growth and commitment to customer data protection.”
Wrong Opening: “I am writing to apply for the Security Analyst position that was advertised on Seek. I have experience with cybersecurity and network security. I believe I would be a good fit for this role at your company.”
Entry-Level Security Analyst Cover Letter Tips
- Emphasize relevant coursework in cybersecurity, networking, or information security
- Showcase CTF competitions, bug bounty programs, or personal lab environments you’ve built
- Demonstrate certifications (Security+, CEH, GIAC) and technical tool proficiency
Entry-Level Cover Letter Sample for Security Analyst
Right Entry-Level Approach: “While completing my Bachelor of Cyber Security at UNSW, I specialized in threat detection and incident response, participating in 8 Capture The Flag competitions including placing 3rd at CrikeyCon 2024. I also completed a 6-month internship at Deloitte’s Cyber Intelligence Centre where I monitored SIEM alerts triaging 200+ incidents, conducted malware analysis on 15 suspicious files, assisted with vulnerability assessments identifying 34 medium-to-high risks, and contributed to incident response documentation. I hold Security+, CEH certifications and built a home security lab using pfSense, Security Onion, and Kali Linux for continuous learning. This blend of academic foundation and practical security experience demonstrated that effective security analysis harmonizes technical skills with threat intelligence and business context—capabilities I’m excited to contribute in a professional security analyst capacity.”
Wrong Entry-Level Approach: “I just finished my cybersecurity degree and I’m interested in security. I know about firewalls and antivirus. I don’t have professional experience yet but I’m willing to learn. Please give me a chance to start my career.”
