Techstrong Research: Combatting CI/CD Security Anti-Patterns

Recently, Techstrong Research released our PulseMeter report, “Tackling CI/CD Security Anti-Patterns.” Our research shed light on the evolving landscape of continuous integration/continuous deployment (CI/CD) pipeline security, drawing from the collective wisdom and experiences of professionals across DevOps, DevSecOps, software development and security disciplines.

Our aim is not merely to explore the challenges but to provide guidance toward actionable steps and best practices that can fortify the backbone of modern software delivery processes. The findings of our research underscore a pressing reality: The security of the software supply chain and CI/CD pipelines is now as critical as the integrity of physical supply chains in traditional sectors.

This comparison is not made lightly; as digital infrastructure becomes the backbone of global commerce and communication, the repercussions of security lapses in software delivery can have widespread and consequential impacts. Our study reveals that the risks to software supply chains demand rigorous attention and strategic action, echoing the necessity for a shift in how organizations approach DevOps and CI/CD security.

A significant portion of our research was dedicated to identifying CI/CD security anti-patterns—practices that, albeit unintentionally, may provide a false sense of comprehensive security and even introduce vulnerabilities into development pipelines. These anti-patterns, such as the incorporation of external code from unverified sources or the adherence to rudimentary security measures without advancing to more robust strategies, significantly broaden the attack surface accessible to cyber adversaries. The research emphasizes the criticality of recognizing and rectifying anti-patterns to help safeguard the software supply chain from potential breaches and attacks.

Insightful Survey Findings: A Wake-Up Call

The survey provides a stark illustration of the current state of CI/CD pipeline security. With 84% of respondents acknowledging the importance of CI/CD pipeline security—motivated by the sobering statistic that over 20% of organizations reported a security incident within their pipelines in the previous year—the message is clear: Pipeline security must be improved beyond current measures.

These incidents showed tangible impacts, including but not limited to delayed deployments and significant data breaches. Moreover, the survey identified source/image repositories and code as particularly vulnerable points within the software development life cycle (SDLC), with a significant emphasis on the risks posed by open source vulnerabilities, secrets exposures and insecure code. This feedback from the field underscores the necessity for a proactive stance on security measures, one that anticipates potential vulnerabilities and implements robust defenses against them.

Drawing from the insights garnered through our research, Techstrong Research advocates for a holistic, strategic approach to enhancing CI/CD pipeline security. This includes the deployment of defensive measures designed to prevent unauthorized tampering with software production processes and the rigorous vetting of CI/CD pipeline artifacts to ensure their integrity through comprehensive role definitions and strict authorization protocols. Our endorsement of the NIST SP 800-204D draft underscores our belief in the necessity of a foundational framework that organizations can adopt to bolster their CI/CD pipeline security. Furthermore, our research shines a spotlight on the pivotal role of software composition analysis (SCA) in fortifying CI/CD pipelines against security threats. SCA facilitates the meticulous tracking of software elements and their dependencies, enabling organizations to identify and mitigate vulnerabilities swiftly. This tool is invaluable not only for preventive security measures but also as a critical component of incident response strategies.

Beyond traditional security measures, the research highlights the use of cloud-native continuous integration approaches, including containerization, to enhance security. These methodologies provide a framework for executing builds and tests within isolated environments, thereby minimizing the risk of conflicts and vulnerabilities. The adoption of containerization offers a myriad of benefits, including standardized packaging, enhanced transportability and improved traceability of software from development through to production.

The PulseMeter report on CI/CD security anti-patterns serves as a clarion call to the industry. The imperative to secure the software supply chain and CI/CD pipelines is undeniable and urgent. In this era of unprecedented digital reliance, our collective commitment to advancing CI/CD pipeline security is not just beneficial—it’s essential. The journey ahead is challenging, but with informed strategies and collaborative efforts, we can significantly reduce the vulnerability of the software we deliver as part of our digital infrastructures.

Skillsoft Taps ChatGPT to Improve Developer Training

Skillsoft today revealed it plans to add generative artificial intelligence (AI) capabilities to its Codecademy online training platform to provide developers with hands-on experience using ChatGPT to write code.

Kunal Ahuja, general manager for Codecademy consumer business at Skillsoft, said the goal is to give developers a more curated path toward teaching them how to define prompts that will result in better code being generated. These enhancements will be made available to Codecademy Plus and Pro users as well as enterprise customers in the coming months, he noted.

There’s no doubt that developers are relying more on generative AI to write code, but not all the output generated by platforms that are based on a general-purpose large language model (LLM) is going to be consistent. Codecademy provides a more immersive experience that enables developers to refine their prompt engineering expertise, said Ahuja.

AI-enabled capabilities include code explanations and project hints to improve debugging skills, along with other real-time feedback surfaced via a virtual coding assistant. There are also courses such as “Prompt Engineering for Software Engineers” available.

Finally, Skillsoft is also providing access to a mock interview simulator that developers can access to help determine if they are ready for a job interview.

As it becomes more apparent that prompt engineering is a skill application development teams will need to master to build and deploy software, there’s a clear need to teach nearly everyone in IT how to craft prompts efficiently. Ultimately, the number of prompts used to generate code will have an impact on the total cost of building software.

In the longer term, Skillsoft plans to build its own LLM using data it collects via its platform to provide training using an LLM that has been trained using code that has been curated, said Ahuja. One of the issues with a general-purpose LLM is that it is trained using examples of code pulled from across the web that varies widely in quality. That can result in outputs of code that have known vulnerabilities or that simply run inefficiently. Of course, it may be just as likely that a developer augmented by generative AI is, depending on their level of expertise, actually delivering higher-quality code.

Despite those concerns, however, it’s still important to provide developers with the training they need today to remain competitive, said Ahuja.

It’s not clear how much code these days is being generated by machines versus humans, but as the volume increases, the number and size of the software builds that need to be managed is only going to increase. Hopefully, as much AI will be applied to the DevOps workflows used to manage those software builds as there is being applied to writing code, but in the short term, at least, DevOps teams might soon find themselves overwhelmed.

The one thing that is certain is DevOps teams have a vested interest in making sure the code being written by developers is of the highest quality possible. After all, whenever there is an issue with that code, it usually falls to the DevOps team to fix it.

ReversingLabs Applies AI to Better Secure Application Binaries

ReversingLabs this week launched a binary analysis tool that uses machine learning algorithms to identify risks before and after applications are deployed.

Erik Thoen, vice president of product management for ReversingLabs, said Spectra Assure makes use of the same core artificial intelligence (AI) technologies the company uses to discover malware within binaries to analyze the entire software package, including first-, second- and third-party components, to identify potential threats.

Thanks to the use of AI, Spectra Assure is able to scan applications that are gigabytes in size in minutes or hours, depending on their complexity, noted Thoen.

That approach is critical because attacks launched against applications are more often aimed at binaries that are deployed in production applications rather than the source code used to create them, he added.

In addition, Spectra Assure can be applied to both open source and proprietary software, said Thoen. In contrast, many legacy scanning tools are designed to only surface potential issues in open source software, he noted.

Spectra Assure is designed to be used by both producers of software and the organizations that deploy software, said Thoen. Organizations that develop software need to be able to identify any security potential issues that may have arisen during the build process, while organizations that consume software need to be assured that there are no issues that will later compromise their IT environments, said Thoen.

ReversingLabs is attempting to fill a gap that exists in many software supply chains between when a software build is completed and deployed, said Thoen. While developers may scan source code for vulnerabilities, it’s not uncommon for changes to be made during the build process that inadvertently create vulnerabilities, said Thoen.

It’s still not clear which teams within organizations are assuming responsibility for the software supply chain. In many cases, DevSecOps teams are securing the software supply chain, but in other instances, cybersecurity teams have been tasked to lock them down. Among organizations that consume software, responsibility for application security might be assumed by either the cybersecurity teams or a procurement office responsible for purchasing software.

Regardless of how software supply chain security is managed, the number of attacks against them has risen sharply. A recent ReversingLabs report found there has been a 1,300% Increase in malicious packages found in open source software platforms since 2020.

Ultimately, it’s only a matter of time before more stringent regulations force the software supply chain security issue. A recent executive order issued by the Biden administration requiring federal agencies to secure software supply chains is a harbinger of stricter controls that enterprise IT organizations must implement. DevSecOps teams, in the meantime, have an opportunity to revisit the workflows that were created in an era where developers tended to overly trust the integrity of software components downloaded from open repositories.

Of course, it may require a catastrophic event to truly galvanize organizations into action, but one way or another, application security is going to improve. The only issue remaining to determine is how expensive a proposition that will be given the potential fines that are likely to be one day levied.

ngrok Previews API Gateway Service to Streamline App Networking

Under an early access program, ngrok today made available an application programming interface (API) gateway that can be consumed as a service.

Rather than having to deploy, maintain, and secure API gateways themselves, application development teams, via a single command or function call, can now invoke a service through which they can route API traffic, authenticate and authorize access, and apply rate-limiting policies using an ngrok policy engine.

ngrok CEO Alan Shreve said this approach also makes it simpler for IT teams to unify ingress management at a time when application networking is becoming more challenging to manage. That approach also reduces friction because instead of being dependent on an IT operations team, it gives developers more direct control over APIs, he added. Today, most access to APIs is granted after developer first create a ticket request in an IT services management (ITSM) platform, noted Shreve.

In addition, the ngrok gateway also streamlines access to APIs spanning multiple clouds and on-premises IT environments in a way that enables organizations to implement a multi-cloud computing strategy, he added. Today, many organizations are locked into a single platform because they are dependent on the API gateway services provided by their cloud service provider, noted Shreve.

Finally, organizations will only need to pay for the API gateway service based on actual usage versus incurring the cost of acquiring a gateway upfront, said Shreve.

Previously, ngrok has been making available software development kits (SDKs) to provide programmable access to its API gateway. The as-a-service option being offered now is the next logical extension of that effort, noted Shreve.

In general, more infrastructure than ever is being consumed as a service, so making available an API gateway service is only the latest example of that larger trend, he added.

Each organization, based on total cost, will naturally need to decide when it makes the most economic sense to consume IT infrastructure as a service; however, as application networking continues to become more challenging to manage at a time when the number of IT professionals with that expertise remains limited. Relying on a service provides a viable alternative for managing what are often hundreds of APIs spanning a distributed computing environment.

It’s not clear yet precisely which teams within an IT organization are assuming responsibility for application networking, but as layer 4 through layer 7 of the networking stack become more programmable, more responsibility for networking can be assumed by DevOps and platform engineering teams. Existing networking teams, meanwhile, continue to manage the physical networking underlays used to route network traffic. Regardless of how application networking evolves, the rigidity that has characterized the delivery of network services is starting to fade away in a way that makes it possible to dynamically invoke networking services as needed.

IT teams must decide how best to approach application networking across legacy monolithic applications, microservices and event-driven applications. The goal, however, should be to eliminate as much friction as possible at a time when applications have become more dependent on networking services than ever.

Veracode Report Shines Spotlight on Massive Application Security Debt

An analysis of more than a million applications published today by Veracode, a provider of a software supply chain security platform, found 42% of applications contained flaws that remained unfixed for longer than a year.

Based on 1,553,022 dynamic analysis scans and 11,429,365 static analysis scans, the report noted that those applications with that level of security debt were found in 71% of the organizations maintaining these applications. Nealy half of organizations (46%) have persistent, high-severity flaws that constitute ‘critical’ security debt. Approximately 63% of applications have flaws in first-party code, while 70% contain flaws in third-party code imported via third-party libraries.

Remediation rates also vary by flaw type. Fixing third-party flaws takes 50% longer, with half the known flaws fixed after 11 months, compared to seven months for first-party flaws.

Collectively, the scan run by Veracode produced 96 million raw static findings, four million raw dynamic findings and 12.2 million raw software composition analysis findings.

Chris Eng, chief research officer for Veracode, said it’s clear too many organizations are kicking application security flaws down the road only to find they don’t have the time to address them properly. Meanwhile, cybercriminal syndicates and nation-states are becoming more adept at exploiting these flaws with each passing day, he added.

In general, there is a lot more focus on software supply chain security in the wake of an executive order issued by the Biden administration that requires federal agencies to identify and remediate security flaws. However, the pace at which enterprise IT organizations are following the lead of the Federal government varies widely. Only a relatively small percentage of the vulnerabilities that exist in applications running in production environments are being exploited, so many enterprise IT teams have yet to prioritize the issue.

However, as more cybercriminals acquire the skills required to discover and exploit those vulnerabilities, it’s only a matter of time before a major application security crisis ensues, noted Eng.

Theoretically, at least, artificial intelligence (AI) should one day soon make it easier to discover and remediate vulnerabilities, but it’s just as likely cybercriminals will use the same capabilities to achieve their own nefarious ends. In fact, it’s largely a race against time before existing application flaws are exploited using AI-based tools and techniques. Application development teams that fix flaws the fastest reduce critical security debt by 75%, from 22% of applications to just over 5%, the Veracode report noted.

Naturally, it’s less costly and simpler to fix security flaws before applications are deployed in a production environment, so the more organizations embrace DevSecOps best practices on the front end, the lower the overall security debt becomes, noted Eng.

It’s not clear whether organizations might decide to replace or consolidate applications to reduce their security debt, but given the overall lack of cybersecurity expertise among application developers, the current level of security debt is likely to continue to rise. The challenge, of course, is that as the security debt rises, the number of developers available to address, unfortunately, remains comparatively constant.

IT Professionals Have Mixed Emotions About AI

A survey of 1,213 IT decision-makers working for small-to-medium enterprises (SMEs) in the U.S., United Kingdom and India published today found nearly half (45%) are worried about the impact artificial intelligence (AI) will have on their job.

Conducted by the research firm Propeller Insights on behalf of JumpCloud, a provider of an IT and cybersecurity management platform, the survey also found more than three quarters (76%) agree their organizations should be investing in AI, with 79% viewing AI as a net positive for their organization.

Most respondents also agree their organizations are approaching AI at exactly the right speed (55%), compared to 22% who said their organization is moving too quickly and 19% who said their organization is moving too slowly.

However, a full 62% also noted that AI is outpacing their organization’s ability to protect against threats, the survey finds.

Tom Bridge, a principal product manager for JumpCloud, said while there is no doubt that AI will change roles within organizations, it’s not likely to replace the need for IT administrators. Instead, IT administrators will be able to manage complex IT environments at much higher levels of scale as AI becomes a force multiplier for managing IT. Many of the low-level tasks that conspire to make managing IT tedious, such as generating reports, will become increasingly automated, noted Bridge.

It’s not clear what impact AI will have on IT roles, but it is arriving at a time when IT organizations are being challenged on several fronts. For example, the survey finds that 56% of respondents are more concerned about their organization’s security posture than they were a year ago. Nearly three-quarters (72%) said any cuts to their security budget would increase organizational risk.

More than half (56%) identified security as their biggest IT challenge, followed by new services and application rollouts (45%), increased work burden (44%) and the cost of remote work solutions (42%). Respondents said network attacks were their biggest challenge (40%), followed by software vulnerability exploits (34%) and ransomware (29%). A full 83% also now require multi-factor authentication (MFA), while two-thirds require biometrics (66%) to access some portion of their IT resources. A total of 83% are also still managing passwords.

More than three quarters (76%) also report increased compliance and regulations requirements in their region.

In addition, a full 88% noted increased vendor prices over the last six months, the survey finds. More than a third of respondents need five to 10 applications to manage worker life cycle (37%), but 22% require 11 or more. Three-quarters (75%) said they would prefer a single tool to do their job over several point solutions.

More than three-quarters (76%) rely on a managed service provider (MSP) to manage some portion of their IT environment, with 42% now relying on an MSP to manage their IT environment completely.

Finally, 57% said their organization has experienced layoffs in the last year. In addition to having to offboard those employees, IT professionals will naturally become more uneasy about their own job security.

Arguably, when it comes to managing IT, there is less certainty today than at any time in recent memory. The challenge, as always, is to aggressively embrace automation as much as possible to reduce a level of IT complexity that is rapidly becoming too complex to manage otherwise.

Legit Security Adds Sensors to Detect Usage of Gen AI Tools to Write Code

Legit Security today announced it has added the ability to detect when developers use generative artificial intelligence (AI) tools to write code to its application security posture management (ASPM) platform.

The ASPM platform developed by Legit Security already has discovery capabilities for application secrets, for example, enabled by sensors that are now being extended to include generative AI tools.

Legit Security CTO Liav Caspi said the overall goal is to allow DevSecOps teams to identify who uses these tools to write which types of code. Each DevSecOps team can then decide how stringently to enforce policies to either ban or limit usage of those tools, he added.

There is no doubt that generative AI tools are increasing developer productivity, but the large language models (LLMs) that provide the ability to generate code were trained using examples of code of varying quality collected from across the web. Much of that code either contains known vulnerabilities or is simply inefficient, which can manifest itself in the output surfaced by a generative AI platform.

The Legit Security ASPM platform, in addition to identifying generative AI tools being used in real-time, can also be employed to scan the LLM itself to identify security risks such as prompt injection and insecure output handling. Unfortunately, most cybersecurity teams are unaware of the extent to which application code generated by a machine might be insecure, so it currently falls to leaders of DevSecOps teams to determine what is an acceptable use of these tools. It may be perfectly fine to rely on a generative AI tool to create a script that will be used for an internal-facing application. However, using the same tool to write business logic that will be exposed to the internet may not be especially prudent.

It’s not clear how much of the code finding its way into software builds is being generated by a machine versus a human. In the longer term, the goal is to be able to identify that code by, for example, detecting substantial changes in the way code is normally written by a human developer, said Caspi.

Of course, while an ASPM may detect usage of generative AI tools that are connected to a corporate environment, there are still plenty of opportunities for developers to use these tools offline to create code that can later be added to a build using a code check-in tool. After all, many developers have used various shadow IT tools to write code for decades. Regardless of who or what wrote that code, however, it should still be reviewed.

In the meantime, the overall size of the codebase that DevSecOps teams will need to manage and secure will only exponentially increase as developers become more productive. Hopefully, more AI capabilities will soon be embedded into DevOps platforms to further automate the management of software builds at a time when many DevOps teams were already finding themselves overwhelmed even prior to the rise of generative AI.

Akamai Launches Gecko Edge Computing Services

Akamai Technologies today launched an initiative that promises to make it simpler to centrally manage and deploy application workloads on edge computing platforms.

Shawn Michels, vice president for product management for cloud computing Akamai, said a Generalized Edge Compute (Gecko) offering leverages the global points of presence (PoPs) that Akamai uses for its content delivery network (CDN) to now deploy application workload managed via the Linode cloud service the company acquired in 2022.

At the core of this offering is a set of virtual machines that enable a full stack of application software to be deployed in an edge computing environment to eliminate latency that would otherwise be encountered when transferring data to a cloud computing environment. The ultimate goal is to provide IT organizations with a federated set of services they can employ to process data where it makes the most sense based on performance requirements, said Michels.

For example, applications infused with artificial intelligence (AI) will need to be able to invoke enough compute resources to run inference engines at the edge, while other less compute-intensive application workloads are best deployed in cloud computing environments, he noted.

Michels added that rather than locking IT teams into a specific architecture, Akamai is committing to meeting IT organizations where they are, including adding support for containers running on Kubernetes clusters in its PoPs later this year.

Akamai has more than 4,100 points of presence around the globe. With the acquisition of Linode, Akamai added a set of cloud computing services to compete directly against hyperscalers such as Amazon Web Services (AWS), Microsoft and Google by making cloud services available at a lower cost at a time when more organizations than ever are concerned about the total cost of IT.

In its first phase of Gecko, Akamai will provide access to virtual machines in 100 locations by the end of the year. Akamai has already deployed Gecko servers in Hong Kong SAR; Kuala Lumpur, Malaysia; Querétaro, Mexico; and Johannesburg, South Africa, as well as in cities without a concentrated hyperscaler presence, including Bogotá, Colombia; Denver, Colorado; Houston, Texas; Hamburg, Germany; and Marseille, France. Deployment of a tenth Gecko region this quarter is planned for Santiago, Chile. Akamai is committing to adding hundreds of cities to its global cloud computing footprint over the next several years.

In the longer term, Akamai also plans to add automated workload orchestration to make it easier for developers to build applications across hundreds of distributed locations.

More workloads than ever are being deployed at the network edge as IT teams look to deploy software closer to the point where data is being created and consumed. That will require extending the reach of existing DevOps workflows to edge computing environments that will be based on everything from x86 and Arm processors to graphical processor units (GPUs).

The challenge, as always, will be finding a way to effectively manage those workloads when the IT teams responsible for them are often physically located thousands of miles away.

Improve Efficiency With Smaller Code Reviews
In software development, code review plays a significant role in helping detect issues in your application’s source code early and promote collaboration among your team members. Breaking down code reviews into more manageable portions can yield great benefits. Review cycles are shorter and more convenient to comprehend when they are smaller. In other words, smaller reviews are easier to comprehend and provide feedback cycles. As a result, we can reduce development, deployment and debugging times while reducing the scope of change in each iteration.

This article presents a discussion on code reviews, why they are important, their benefits and why smaller code review cycles are more effective than larger ones.

What is Code Review?

Code review is defined as a software development process which involves reviewing code written by other developers. As part of the development process, it aims to improve code quality, ensure compliance with standards and identify and fix problems early on. Code reviews play a role in software development as they help catch errors before they turn into significant issues.

Peer reviews allow developers to detect errors or defects in each other’s code. By reviewing each other’s code, developers are able to identify bugs and flaws in the code. It helps deliver code that is secure and sustainable, adheres to standards and detects and resolves problems early in the development life cycle.

This can either be a formal process, where code is systematically evaluated according to a checklist or set of guidelines, or an informal process, where code is reviewed ad hoc. Code review can be performed by the same developers working on the code or by other developers with expertise in the relevant domain or technology.

By engaging in the exchange of feedback and actively participating in code reviews, we can ensure that the code is well-organized, easy to comprehend, adapt and extend over time. To be effective, it’s essential that everyone on the team is on the same page when it comes to their expectations and goals regarding these reviews.

Here are the key benefits of code review at a glance:
- Identify bugs and issues
- Improve code quality, consistency and maintainability
- Enforce coding standards
- Foster team collaboration
- Promote knowledge sharing
Best Practices of Code Review

Here are some of the best practices you should follow to improve your code review process:
- Review small units of code
- Set clear objectives and guidelines
- Involve multiple reviewers
- Provide constructive and respectful feedback
- Use code review tools
- Prioritize high-risk areas
- Balance attention to detail with time efficiency
- Encourage collaboration and learning
- Set realistic deadlines
- Follow up and close the loop
Automating the Code Review Process

Automated code reviews can help you enhance collaboration amongst your team and reduce the time spent in each cycle. Your developers can improve code quality and maximize productivity by automating the development workflow.

Here are the key benefits of automating the code review process:
- Enhances code quality
- Improves productivity
- Enhances code quality
- Improves collaboration
- Fosters learning opportunities
The Problem With Large Code Reviews

The traditional approach to code review often involves reviewing large chunks of code in a single session. Although this approach is initially efficient, it can lead to multiple problems. You will need more effort and spend more time reviewing large chunks of code. If code reviews are extensive and take longer to complete, it can often result in decreased attention to detail. Due to this, the likelihood of missing crucial errors and reviewer fatigue will increase, resulting in delays in feedback and completing the code review process.

The Benefits of Smaller Code Reviews

When the code review cycle is small, it becomes easier to track deployment changes easily. Smaller code reviews continuously improve development, deployment and debugging times and reduce the radius of a change set. As a result, it promotes faster deployment and helps identify issues easily and early in the software development life cycle.

Once a code review cycle is complete, the code goes through many steps before it finally reaches the production phase. Monitoring the application’s performance and detecting bugs (if any) is much easier when you make only minimal changes to your code. When the changes are small, it is easier to track the application’s behavior and detect bugs.

Here are some benefits of adopting smaller code reviews:

Focused Review

Reviewing smaller chunks of code enables you to analyze the code in a more focused and in-depth manner. This helps reviewers focus on specific functionality or components, leading to more accurate feedback.

Reduced Cognitive Load

Limiting the amount of code to review reduces cognitive overload for both developers and reviewers. Smaller code review cycles can be more efficient because they break down the review process into more manageable chunks. As a result, you’ll be able to evaluate code quality in a much more effective and efficient manner and identify potential issues or improvements more easily.

Faster Feedback Loop

Smaller code reviews can significantly speed up the feedback loop in the development process. Hence, feedback cycles will be faster, i.e., you will be able to receive feedback faster, resulting in quicker iterations and faster software delivery. The smaller the review, the easier it is to digest and the faster the feedback cycle.

Enhanced Collaboration

Smaller code reviews allow for more focused discussions and collaboration between reviewers and developers. Most importantly, since you can handle concerns effectively and efficiently, you can engage in more productive discussions. The efficiency and effectiveness of code reviews improves when the expectations of all stakeholders are aligned.

Measuring Success

To measure the success of smaller code reviews, consider the metrics and approaches given below:

Defect Detection Rate

This is a measure of the number of defects or issues identified during a code review cycle relative to the number of defects found later in testing or in the production environment. Note that a higher defect detection rate indicates you’re able to detect defects effectively.

Review Efficiency

Calculate the time it takes to review a chunk of code to understand the pace and efficiency of the code review process.

Feedback Quality

Assess the quality of the feedback provided during reviews, such as checking if the feedback is constructive, clear and actionable. Note that if the feedback is of high quality, it would typically yield better code improvements and learning opportunities for your team.

Cycle Time

The duration of the code review process is an indicator of efficiency. A shorter cycle time suggests an efficient review process, but quality should not be compromised.

Automated Checks Integration

Evaluate how effectively automated tools are integrated into the code review process to detect common issues and reduce the manual effort required in reviews.

Knowledge Sharing

Assess how well the code review process facilitates knowledge sharing and cross-team learning. This can be observed through the diversity of reviewers and the nature of the discussions in the review process.

Bug Rates Post-Release

Monitor the incidence of bugs or issues in the code post-release. A decrease in this rate can indicate that the code review process is effectively catching and addressing potential problems before release.

Conclusion

Code review helps produce code that is highly performant, scalable, secure and compliant with the recommended standards. Code reviews can make the codebase easily understood, flexible and scalable. A collaborative approach to code review can yield several benefits, such as promoting a culture of continuous development and learning, maintaining an organized codebase with clean code and clear structure, helping detect and resolve issues quickly, etc.
