They work alongside experienced security teams to identify vulnerabilities, perform security testing, review code, and help implement secure development practices. Their role often involves learning about application security tools, methodologies, and compliance requirements while gaining hands-on experience in a real-world environment. This internship is ideal for students or recent graduates interested in cybersecurity and software development.

What are the key skills and qualifications needed to thrive as an application security intern, and why are they important?

Familiarity with security scanning tools, vulnerability assessment platforms, and systems like OWASP ZAP or Burp Suite is typically required. Strong analytical thinking, attention to detail, and effective communication skills help interns identify risks and collaborate with development teams. These skills and qualities are crucial for detecting vulnerabilities early, supporting secure software development, and contributing to organizational risk mitigation.

  • Collaborate with CISO teams, technology partners, infrastructure teams, application developers, and risk stakeholders to strengthen security controls and support internal policy, regulatory, audit, and governance expectations.
  • Help prepare security documentation, metrics, dashboards, procedures, job aids, and status updates that communicate risks, findings, remediation progress, and key outcomes to technical and non-technical audiences.
  • Support vulnerability management, access management, security awareness, compliance, and control testing activities by collecting data, analyzing results, tracking actions, and helping teams drive timely remediation.
  • Research emerging cybersecurity threats, industry trends, financial services security practices, and security technologies while contributing to projects that protect critical financial market infrastructure.

What will help you succeed

  • Currently pursuing a bachelor’s degree in Cybersecurity, Information Security, Computer Science, Information Technology, Computer Engineering, Management Information Systems (MIS), Technology Management, or a related field.
  • Expected graduation date: Fall 2027 or Summer 2028
  • Minimum GPA: 3.2
  • Authorization to work permanently in the United States without current or future sponsorship.
  • Foundational understanding of cybersecurity concepts and frameworks, IT risk, networking, cloud, operating systems, identity and access management, vulnerability management, or security governance.

Preferred

  • Coursework, projects, prior work, internship, student organization, volunteer, or leadership experience related to cybersecurity, information security, IT risk, audit, compliance, technology operations, or financial services technology.
  • Strong interest in cybersecurity, financial services, critical infrastructure, technology risk, operational resilience, or protecting systems and data in a highly regulated environment.
  • Exposure to tools, topics, or frameworks such as SIEM platforms, vulnerability scanning, endpoint security, cloud security, scripting or automation, data analysis, Microsoft Office 365, Excel, PowerPoint, Power BI, ServiceNow, Jira, NIST Cybersecurity Framework, ISO 27001, SOC, or security awareness practices.
