Mr David Chen
Chief Information Security Officer
Commonwealth Bank of Australia
Level 7, 201 Sussex Street
Sydney NSW 2000
Dear Mr Chen,
I am writing to express my strong interest in the Cyber Security Analyst position within CBA’s Cyber Defence Centre. With my Master of Cyber Security from UNSW Canberra, CISSP certification, and five years of experience protecting critical financial infrastructure from advanced persistent threats, I am excited to contribute to CBA’s industry-leading cyber security program whilst defending against the evolving threat landscape targeting Australia’s banking sector.
In my current role as Senior Security Analyst at Westpac, I monitor and investigate security incidents across our digital banking platforms, analyzing over 50,000 security events daily using SIEM tools including Splunk and QRadar. My proactive threat hunting initiatives have identified 15 previously undetected attack campaigns, including a sophisticated nation-state actor attempting to compromise our payment processing systems. I successfully led the incident response that contained the breach within 2 hours, preventing potential losses exceeding $12 million whilst maintaining customer service availability. My expertise spans vulnerability assessment, penetration testing, malware analysis, and implementing security controls aligned with NIST Cybersecurity Framework and APRA CPS 234 requirements.
What particularly attracts me to Commonwealth Bank is your commitment to cyber security excellence and your investment in cutting-edge security technologies including AI-powered threat detection and zero-trust architecture implementation. During my previous role with the Australian Cyber Security Centre, I contributed to threat intelligence analysis that informed national cyber security advisories and supported critical infrastructure protection across the banking sector. My experience includes developing security policies, conducting security awareness training, and collaborating with law enforcement agencies during cyber crime investigations. My Security+ and GCIH certifications, combined with ongoing research into emerging threats, ensure I remain current with the rapidly evolving cyber security landscape.
I would welcome the opportunity to discuss how my cyber security expertise, threat analysis capabilities, and commitment to protecting Australia’s financial infrastructure can contribute to CBA’s continued leadership in banking security and customer trust. Thank you for considering my application, and I look forward to the possibility of joining your world-class security team.
Sincerely,
Jordan Park
CISSP, Security+, GCIH

Top Mistakes to Avoid in a Cyber Security Cover Letter
- Being vague about security achievements: Instead of “improved security,” specify “implemented multi-factor authentication that reduced account compromise incidents by 78% whilst maintaining user experience satisfaction scores above 85%.”
- Not quantifying threat impact: Security work prevents losses – include metrics like threats blocked, incidents contained, compliance improvements, or potential damages prevented through your interventions.
- Overlooking compliance and governance: Modern security involves regulatory requirements – show understanding of frameworks like ISO 27001, NIST, APRA CPS 234, or Privacy Act compliance.
- Ignoring business context: Security exists to enable business – demonstrate understanding of how security controls balance protection with operational efficiency and user productivity.
- Underestimating communication skills: Security professionals must explain complex threats to non-technical stakeholders – show your ability to communicate security risks and recommendations clearly.
How to Tailor Your Cover Letter to a Job Ad
- Match specific security domains: Network security roles emphasize different skills than application security or digital forensics – align your experience with their particular security focus areas.
- Address industry-specific threats: Financial services face different attack vectors than healthcare or critical infrastructure – show understanding of sector-specific security challenges.
- Highlight relevant tools and platforms: If they mention specific SIEM systems, security frameworks, or compliance requirements, ensure you address relevant experience or learning capacity.
- Reference their security initiatives: Research their recent security investments, threat disclosures, or industry security leadership, then explain how your skills could support similar initiatives.
How to Sign Off Your Cyber Security Cover Letter
- Professional security closing: Use “Sincerely,” “Kind regards,” or “Respectfully” to maintain appropriate formality for security-conscious organizations
- Security credentials emphasis: Include relevant certifications after your name (CISSP, CISM, Security+) to immediately establish your security qualifications and professional development
- Complete professional profile: Include phone number, professional email, LinkedIn profile, and carefully selected technical profiles that demonstrate security expertise without revealing sensitive information
