The Amazon Cloud Security Internship in Summer 2019 was a 12-week immersive professional program where students integrated with AWS security teams to build automated defense systems. Interns focused on scaling security through code, managing identity and access, and mitigating risks across global infrastructure while being evaluated against Amazon’s rigorous Leadership Principles for full-time conversion.
The Significance of the 2019 AWS Security Internship
The summer of 2019 represented a pivotal era for Amazon Web Services (AWS). At that time, cloud adoption was transitioning from "early majority" to "late majority," and the complexity of securing hyper-scale infrastructure was increasing exponentially. For an intern entering the Amazon Cloud Security space, the experience was not merely about shadow-monitoring or basic administrative tasks; it was about engineering.
During this period, AWS was heavily promoting the concept of "Security as Code." Interns were placed in the "Securo" (Security) organizations, which included teams focused on Application Security, Infrastructure Security, and Security Operations. The primary goal for any 2019 intern was to deliver a "capstone" project—a significant piece of software or a process improvement that solved a real-world security challenge for millions of customers.
Unlike traditional internships that might focus on manual audits, the 2019 experience was deeply rooted in automation. If a security problem could be solved by a human, the goal was to write a script or service to ensure that human would never have to solve it again. This mindset of "building for scale" was the cornerstone of the AWS security culture.
The Application and Interview Journey
Navigating the hiring process for the Summer 2019 cohort required a blend of software engineering proficiency and a specialized understanding of security primitives. The process typically began in late 2018 or early 2019 and followed a standardized path.
The Initial Assessment
Most candidates started with an online assessment (OA). For security engineering roles, this often included coding challenges in languages like Python, Java, or C++, alongside multiple-choice questions regarding networking, encryption, and operating system security. The coding portion was not just about getting the right answer but about the efficiency of the algorithm (Big O notation).
Technical and Cultural Interviews
The final round usually consisted of two or more back-to-back interviews. Amazon’s interview methodology is famous for its focus on Leadership Principles (LPs). Candidates had to provide "STAR" (Situation, Task, Action, Result) format answers that demonstrated qualities like "Ownership," "Dive Deep," and "Insist on the Highest Standards."
From a technical standpoint, interns were expected to understand:
- The Shared Responsibility Model: Knowing what AWS secures (the cloud) versus what the customer secures (in the cloud).
- Identity and Access Management (IAM): The intricacies of policies, roles, and the principle of least privilege.
- Encryption: The difference between encryption at rest and in transit, and how AWS Key Management Service (KMS) functions.
- Network Security: Virtual Private Clouds (VPC), Security Groups, and Network ACLs.
Core Technical Domains and Tools of 2019
An intern’s day-to-day life in 2019 involved heavy usage of the AWS console, but more importantly, the AWS CLI and SDKs. The technical landscape was focused on shifting security "left" in the development lifecycle.
Automation with Python and Boto3
Python was the lingua franca of AWS security in 2019. Interns frequently used the Boto3 library to interact with AWS services. A typical project might involve writing a Lambda function that automatically detaches over-permissive IAM policies or wipes public S3 buckets that were intended to be private.
Monitoring and Logging
Understanding data flow was critical. Interns worked with AWS CloudTrail for API auditing, Amazon GuardDuty for intelligent threat detection, and Amazon CloudWatch for real-time monitoring and alerting. The ability to query logs using Amazon Athena or analyze them in an ELK (Elasticsearch, Logstash, Kibana) stack was a highly valued skill.
Infrastructure as Code (IaC)
2019 saw a massive push toward AWS CloudFormation and the early adoption of the AWS Cloud Development Kit (CDK). Security interns were often tasked with creating "service control policies" (SCPs) or CloudFormation templates that had security best practices "baked in" by default. This ensured that any developer within the company could spin up infrastructure that was pre-validated for compliance.
The Lifecycle of an Intern Project
The hallmark of the Amazon internship was the project. Each intern was assigned a manager and a "mentor" (a peer on the team) to guide them through a 12-week delivery cycle.
- The One-Pager/Six-Pager: In keeping with Amazon’s unique writing culture, interns did not use PowerPoint. Instead, they had to write a detailed document outlining their project proposal, the problem statement, and the technical design.
- The Design Review: Interns presented their document to the team. Senior engineers would "critique" the design, not to be harsh, but to ensure the solution was scalable and secure. This taught interns the value of "Earn Trust" and "Are Right, A Lot."
- Implementation: The middle 6–8 weeks were spent coding and testing. Interns followed standard Amazon development practices, including code reviews (CRs) and unit testing.
- The Final Presentation: In the final week, interns presented their results to their organization, demonstrating the impact of their work (e.g., "Reduced unauthorized API calls by 15%" or "Automated 100 hours of manual security auditing per month").
Amazon’s Leadership Principles in the Security Context
To succeed as a security intern in 2019, one had to live the Leadership Principles. While all 14 (at the time) were important, three stood out as vital for security professionals:
- Ownership: Security is everyone’s job. Interns were expected to look beyond their specific project. If they saw a security flaw in a different system, they were expected to flag it or fix it, rather than saying "that’s not my job."
- Dive Deep: Security issues are often hidden in the details. A security intern had to be able to look at a packet trace or an IAM policy and understand the specific bit-level or logic-level failure that could lead to an exploit.
- Customer Obsession: In the context of AWS Security, the "customer" was often other Amazon developers or external AWS users. The goal was to make security "invisible"—to protect the user without hindering their productivity.
Relocation and Office Life: The Pre-Remote Era
In Summer 2019, the internship was almost exclusively in-person. Interns were primarily located in major hubs such as Seattle, Washington (HQ1); Herndon, Virginia (HQ2/Public Sector); or Palo Alto, California.
Amazon provided a relocation stipend or corporate housing, which fostered a strong social community among interns. "Intern events" were common, ranging from boat cruises on Lake Washington to technical "lunch and learns" with Distinguished Engineers. This in-person interaction was crucial for networking, as it allowed interns to meet with leaders across different orgs—something that became much harder during the subsequent shift to remote work in 2020.
Transitioning from Intern to Full-Time
The ultimate goal for most 2019 interns was the "Return Offer." The conversion process was based on the successful completion of the project and the manager’s evaluation of the intern’s performance against the Leadership Principles.
The "Bar Raiser" culture meant that to be hired full-time, the intern had to perform better than 50% of the people currently in that role at Amazon. For those who received offers, the transition involved a formal review of their technical contributions and their ability to operate independently. Many 2019 security interns transitioned into Security Engineer I or Cloud Security Architect roles, forming the backbone of the security teams that managed the unprecedented cloud growth of the early 2020s.

Frequently Asked Questions
What was the average compensation for an AWS Security Intern in 2019?
While exact figures varied by location, 2019 interns typically received a monthly salary ranging from $7,000 to $9,000, depending on their degree level (Bachelors, Masters, or PhD). Additionally, a housing stipend of approximately $2,000 to $2,500 per month was common for those relocating to Seattle or the Bay Area.
Did I need to be an expert in AWS before starting the internship?
No. While a basic understanding of the cloud was helpful, Amazon looked for "builders"—students with strong foundational knowledge in computer science, networking, and security logic. The first few weeks of the internship included "Day One" training and access to internal AWS training modules to bring interns up to speed.
How much coding was actually required for a security role?
A significant amount. In 2019, the distinction between a Software Development Engineer (SDE) and a Security Engineer (SE) was narrowing. Security interns were expected to write production-quality code, participate in code reviews, and maintain the software they built throughout the summer.
What happened if my project wasn't finished by the end of the 12 weeks?
The goal was "delivery," but Amazon recognized that 12 weeks is a short window. If a project wasn't 100% finished, the intern was evaluated on the progress made, the quality of their documentation, and their ability to hand over the project to a full-time engineer. A well-documented, 80%-complete project was often valued more than a "finished" project that lacked scalability or security testing.
What were the most common mistakes interns made in 2019?
The most common mistake was not "Asking Questions." Some interns would spend days stuck on a technical hurdle because they were afraid to look "unprepared." Amazon’s culture encourages "Diving Deep," but it also values efficiency. Successful interns learned to time-box their independent troubleshooting before seeking help from their mentor.
Next Steps for Aspiring Cloud Security Professionals
Reflecting on the 2019 experience provides a roadmap for anyone looking to enter the field today. While the specific tools like Amazon GuardDuty and AWS IAM have matured, the underlying requirement to think like an owner and build for scale remains unchanged.
If you are a student in 2026 aiming for a similar role, focus on mastering Infrastructure as Code, understanding the security implications of Generative AI, and honing your ability to write clear, concise technical documentation. The "Securo" mindset—protecting the customer at all costs through engineering excellence—is a timeless career foundation.
