AI Code Assistants in Secure Software Development: Opportunities, Risks, and Best Practices

1. Introduction

Context:

In recent years, Artificial intelligence (AI) has become deeply integrated into software engineering, transforming the way developers write, test and maintaining code. One of the most prominent applications of AI in this domain is the emergence of AI-powered code assistants such as GitHub Copilot. These tools leverage large language models trained on vast repositories of code to provide real time code suggestions, generate functions, and accelerate development processes. As a result they are being rapidly adopted in both industry and academia, offering the promise of increased productivity, faster prototyping and reduced development effort. However, their growing influence has sparked critical conversations about the safety, reliability and ethical use of AI-generated code especially in environments where software security is paramount.

Problem/Gap:

Despite the impressive capabilities of AI code assistants, their integration into secure software development workflows introduces a number of unresolved risks and challenges. These tools rely on large-scale language models trained on billions of lines of code scrapped from public repositories, many of which contain insecure, outdated, or non-compliant practices. Because the models learn patterns statistically, without truly understanding programming logic or security policies. They may generate code that looks syntactically correct but is functionally unsafe. For instance, they can suggest hardcoded passwords improper input validation, or the use of deprecated cryptographic functions, practices that can lead to critical vulnerabilities if deployed in real-world systems.

What’s more concerning is that many developers, especially those with limited security expertise, may over-rely on these suggestions, trusting them as correct due to their apparent fluency and speed. This over-reliance can result in false sense of security, where insecure code is unknowingly accepted and integrated into production. Compounding the issue is the lack of built-in, automated security verification in most AI code assistants, unlike dedicated security tools, these assistants do not actively scan their own outputs for flaws. As organisations move towards DevSecOps and continuous deployment, this introduces a serious gap how can we leverage the productivity gains of AI code assistants without compromising the integrity and security of the software?

Objective:

The objective of this paper is to critically examine the dual impact of AI code assistants on secure software development, highlighting their potential to improve coding efficiency and developer productivity while also analysing the security risks they may introduce.

Background :

The rapid advancement of artificial intelligence has led to the emergence of AI-powered tools that are reshaping the software development landscape. Among these, AI code assistants such as GitHub Copilot, Amazon CodeWhisperer, and Tabnine have gained considerable popularity for their ability to assist developers by generating code suggestions, completing functions, and offering real-time support during programming tasks. These tools are built on large language models (LLMs) like OpenAI’s Codex, which are trained on vast datasets containing billions of lines of publicly available code. As a result, AI code assistants are capable of producing human-like, functional code with minimal developer input.

While these tools offer significant benefit, such as increased productivity, reduced development time, and lower entry barriers for novice programmer, they also raise critical questions about software security. Secure software development is a disciplined approach that integrates security practices throughout the software development lifecycle (SDLC), emphasizing threat mitigation, vulnerability prevention, and compliance with industry standards. The adoption of AI code assistants introduces new dynamics into this process. Because these tools are not inherently aware of context, application architecture, or security requirements, they may generate insecure code patterns or replicate vulnerabilities present in their training data.

As organizations increasingly adopt DevSecOps practices, where security is integrated continuously and automatically into development pipelines, the use of AI code assistants presents both opportunities and challenges. Understanding how these tools align with secure coding practices, and what risks they may pose if used carelessly, is essential for leveraging their potential without compromising security.

2. Software Development Life Cycle (SDLC)

Several software developments models or approaches have been proposed and applied during the last 30 years. Each model has its characteristics, advantages and disadvantages, but common to them all is that they are typically not focusing on security [2] (p.1111). A selection of five prominent development models is briefly analysed and compared in [3]. These are:

• Waterfall model
• Iteration model
• V-shaped model
• Spiral model
• Agile model, aka. XP (Extreme Programming).

The waterfall model is the classical and most heavy-weight approach to software development, whereas the agile model is the most light-weight and flexible approach. We will briefly describe the waterfall and agile models, as they represent very different approaches to secure programming. Figure 1 shows the waterfall model.

The basic idea behind the waterfall model is that the tasks of each phase must be fully completed before the next phase, which is symbolized by the waterfall metaphor where water only flows downwards. This also implies that the complete set of requirement is must be defined and fixed at the beginning of the project. In case it is necessary to revisit a previous stage, then a costly overhead is to be expected (metaphorically make water flow upwards), so this should be avoided. However, it is typically the case that requirements have to be changed in the middle of a software development project, so that many software development projects based on the waterfall model have suffered large blow-outs in cost and time.

As a reaction to the rigid structure of the waterfall model several other models have been proposed, where the most recent and radical is the agile model (also known as XP: eXtreme Programming) illustrated in Figure 2 below.

The basic idea behind the agile model is that new or evolving requirements can be specified in parallel with, or after already implemented requirements [4]. This is possible by splitting the development into separate stories where each story covers a set of requirements implemented as functions that can be developed and tested more or less independently of other stories. Each cyclic iteration in the agile model is a sprint which can be completed in only a few weeks. The major drawback of the agile model is that it often does not scale well to large and complex development projects.
