In this content, I will elaborate on the importance of DevSecOps, how to assess its relevance for your organization, and the necessary actions to integrate this practice into your company.
What is DevSecOps?
DevSecOps is an approach to product development that integrates security from the very beginning. The main goal is to reduce the number of defects in the final product by addressing security concerns proactively throughout the software development process. Instead of dealing with the consequences of existing issues, the focus is on preventing their occurrence altogether.
It can be likened to planning for a warm house during construction rather than insulating it after realizing it's too cold. With DevSecOps, the emphasis is on avoiding vulnerabilities and weaknesses in the first place and taking necessary measures at every stage of development to ensure a secure and robust end product.
Pre-commit Checks. Code inspection to detect the presence of sensitive information (such as passwords, secrets, tokens, etc.) that should not be included in the Git history.
Commit-time Checks. Checks performed during the commit process to ensure the correctness and security of the code in the repository.
Post-build Checks. Checks carried out after the application has been built, including artifact testing (e.g., docker images).
Test-time Checks. Vulnerability testing of the deployed application (e.g., API scanning for common vulnerabilities).
Deploy-time Checks. Checks performed during the application deployment to assess the infrastructure for vulnerabilities.
A few years ago, DevSecOps was primarily relevant for large companies with numerous products and extensive development teams. However, today, its importance is gradually extending to smaller players in the industry.
Previously, development efforts prioritized swiftly creating a pilot version and dealing with security concerns later. Yet, investors now grasp the significance of airtight security and raise their inquiries. As a result, DevSecOps becomes increasingly relevant for a broader audience. However, for teams with fewer than 50 developers, security concerns may not be as pressing, and they are often handled through simpler, standard methods (in practice). Their main focus is on business functionality, with security addressed in fragments after product creation. Vulnerabilities are often identified in finished products using free scanners and penetration testing, and then remedied. As businesses grow and demand higher quality, security gains paramount importance and becomes deeply ingrained in the development process.
Consequently, companies reach a new level with their unique requirements. The market demands faster responses, driving the significance of the Time To Market metric. This urges the automation of every feasible aspect. Code is written, built, and deployed swiftly, showcasing DevOps in full effect - automating build, delivery, and deployment processes. As the transition to a pipeline-driven development occurs, security becomes a critical concern, leading us to the world of DevSecOps.
What are the Business Benefits?
The advantages for businesses are evident. As development speeds up with business growth, security should also keep pace, preferably taking a proactive approach. This is where DevSecOps becomes invaluable. When security practices are well-established and seamlessly integrated into the pipeline, automation becomes the norm. Detecting and rectifying bugs during the product's creation phase prevents a cascade of issues in subsequent products, saving significant resources.
Furthermore, meeting investor and client demands for prompt product delivery is crucial. Discovering errors at the final stage can lead to time-consuming fixes, causing delivery delays, contract breaches, and potential penalties. Hence, prioritizing security throughout ensures smoother product development without setbacks.

Security in Software Development
The industry is well acquainted with various practices that aid in ensuring security at different development stages. But what exactly is security? Can there be a scenario where no vulnerabilities exist? Unfortunately, the notion of being entirely free of vulnerabilities is implausible, given the constant emergence of new ones and the vigilance of security researchers. Thus, the primary objective is to minimize the number of "holes," swiftly detecting and rectifying them before malicious actors exploit them.
To achieve this goal, the implementation of security practices becomes vital. Drawing an analogy with an automotive assembly line, we can better understand the importance of security throughout the development process.
During the blueprint phase, which is akin to the design stage in software development, we assess the software's architecture for correctness, authentication elements, database integration, and appropriate platform selection.
As we proceed to the parts stage, which corresponds to the integration of third-party libraries, we must ensure their functionality and check for any vulnerabilities or licensing issues.
The framework phase mirrors the creation of our own code, where we adhere to secure coding practices, prioritize data protection, and encryption.
The installation of parts phase relates to the assembly of the software, allowing us to conduct basic dynamic tests, verifying assembly correctness and library usage.
Subsequently, in the testing stage, we perform comprehensive tests to observe how the software functions in its infrastructure and interacts with users.
Finally, the production phase marks the product's release to the world, where constant monitoring ensures its performance under real-world conditions.
Throughout each development stage, security should be thoroughly evaluated, much like checking for installed airbags, a functioning steering wheel, a key for the door, working seatbelts, and appropriate brakes in a car.
Conducting timely and continuous checks at each stage is essential to ensure security is ingrained within the development process, avoiding last-minute fixes and mitigating potential risks.
The Path of Application Security Practices Transformation

Exploring the Landscape of IaC Tools
The IaC paradigm is widely embraced in modern software development, offering a range of tools for deployment, configuration management, virtualization, and orchestration. Prominent containerization and orchestration tools like Docker and Kubernetes employ YAML to express the desired end state. HashiCorp Packer is another tool that leverages JSON templates and variables for creating system snapshots.
The most popular configuration management tools, namely Ansible, Chef, and Puppet, adopt the IaC approach to define the desired state of the servers under their management.
Ansible functions by bootstrapping servers and orchestrating them based on predefined playbooks. These playbooks, written in YAML, outline the operations Ansible will execute and the targeted resources it will operate on. These operations can include starting services, installing packages via the system's package manager, or executing custom bash commands.
Both Chef and Puppet operate through central servers that issue instructions for orchestrating managed servers. Agent software needs to be installed on the managed servers. While Chef employs Ruby to describe resources, Puppet has its own declarative language.
Terraform seamlessly integrates with other IaC tools and DevOps systems, excelling in provisioning infrastructure resources rather than software installation and initial server configuration.
Unlike configuration management tools like Ansible and Chef, Terraform is not designed for installing software on target resources or scheduling tasks. Instead, Terraform utilizes providers to interact with supported resources.
Terraform can operate on a single machine without the need for a master or managed servers, unlike some other tools. It does not actively monitor the actual state of resources and automatically reapply configurations. Its primary focus is on orchestration. Typically, the workflow involves provisioning resources with Terraform and using a configuration management tool for further customization if necessary.
For Chef, Terraform provides a built-in provider that configures the client on the orchestrated remote resources. This allows for automatic addition of all orchestrated servers to the master server and further customization using Chef cookbooks (Chef's infrastructure declarations).

Popular Infrastructure as Code Tools
Terraform
Terraform, introduced by HashiCorp in 2014, is an open-source Infrastructure as Code (IaC) solution. It operates based on a declarative approach to managing infrastructure, allowing you to define the desired end state of your infrastructure in a configuration file. Terraform then works to bring the infrastructure to that desired state. This configuration is applied using the PUSH method. Written in the Go programming language, Terraform incorporates its own language known as HashiCorp Configuration Language (HCL), which is used for writing configuration files that automate infrastructure management tasks.
Download: https://github.com/hashicorp/terraform
Terraform operates by analyzing the infrastructure code provided and constructing a graph that represents the resources and their relationships. This graph is then compared with the cached state of resources in the cloud. Based on this comparison, Terraform generates an execution plan that outlines the necessary changes to be applied to the cloud in order to achieve the desired state, including the order in which these changes should be made.
Within Terraform, there are two primary components: providers and provisioners. Providers are responsible for interacting with cloud service providers, handling the creation, management, and deletion of resources. On the other hand, provisioners are used to execute specific actions on the remote resources created or on the local machine where the code is being processed.
Terraform offers support for managing fundamental components of various cloud providers, such as compute instances, load balancers, storage, and DNS records. Additionally, Terraform's extensibility allows for the incorporation of new providers and provisioners.
In the realm of Infrastructure as Code (IaC), Terraform's primary role is to ensure that the state of resources in the cloud aligns with the state expressed in the provided code. However, it's important to note that Terraform does not actively track deployed resources or monitor the ongoing bootstrapping of prepared compute instances. The subsequent section will delve into the distinctions between Terraform and other tools, as well as how they complement each other within the workflow.

One possible solution for creating a universal configuration is to use the Pulumi project, which allows for deploying applications to various clouds (GCP, Amazon, Azure, AliCloud), Kubernetes, providers (such as Linode, Digital Ocean), virtual infrastructure management systems (OpenStack), and local Docker environments.
Pulumi integrates with popular CI/CD systems and Git repositories, allowing for the creation of infrastructure as code pipelines.
Users can automate the deployment and management of infrastructure resources as part of their overall software delivery process.
SaltStack
SaltStack is a powerful Infrastructure as Code (IaC) tool that automates the management and configuration of infrastructure resources at scale. It provides a comprehensive solution for orchestrating and managing infrastructure through a combination of remote execution, configuration management, and event-driven automation.
SaltStack enables remote execution across a large number of servers, allowing administrators to execute commands, run scripts, and perform tasks on multiple machines simultaneously. It provides a robust configuration management framework, allowing users to define desired states for infrastructure resources and ensure their continuous enforcement.
SaltStack is designed to handle massive infrastructures efficiently, making it suitable for organizations with complex and distributed environments.
The SaltStack solution stands out compared to others mentioned in this article. When creating SaltStack, the primary goal was to achieve high speed. To ensure high performance, the architecture of the solution is based on the interaction between the Salt-master server components and Salt-minion clients, which operate in push mode using Salt-SSH.
The project is developed in Python and is hosted in the repository at https://github.com/saltstack/salt.
The high speed is achieved through asynchronous task execution. The idea is that the Salt Master communicates with Salt Minions using a publish/subscribe model, where the master publishes a task and the minions receive and asynchronously execute it. They interact through a shared bus, where the master sends a single message specifying the criteria that minions must meet, and they start executing the task. The master simply waits for information from all sources, knowing how many minions to expect a response from. To some extent, this operates on a "fire and forget" principle.
In the event of the master going offline, the minion will still complete the assigned work, and upon the master's return, it will receive the results.
The interaction architecture can be quite complex, as illustrated in the vRealize Automation SaltStack Config diagram below.
When comparing SaltStack and Ansible, due to architectural differences, Ansible spends more time processing messages. However, unlike SaltStack's minions, which essentially act as agents, Ansible does not require agents to function. SaltStack is significantly easier to deploy compared to Ansible, which requires a series of configurations to be performed. SaltStack does not require extensive script writing for its operation, whereas Ansible is quite reliant on scripting for interacting with infrastructure.
Additionally, SaltStack can have multiple masters, so if one fails, control is not lost. Ansible, on the other hand, can have a secondary node in case of failure. Finally, SaltStack is supported by GitHub, while Ansible is supported by Red Hat.
SaltStack integrates seamlessly with cloud platforms, virtualization technologies, and infrastructure services.
It provides built-in modules and functions for interacting with popular cloud providers, making it easier to manage and provision resources in cloud environments.
SaltStack offers a highly extensible framework that allows users to create custom modules, states, and plugins to extend its functionality.
It has a vibrant community contributing to a rich ecosystem of Salt modules and extensions.
Chef
Chef is a widely recognized and powerful Infrastructure as Code (IaC) tool that automates the management and configuration of infrastructure resources. It provides a comprehensive framework for defining, deploying, and managing infrastructure across various platforms and environments.
Chef allows users to define infrastructure configurations as code, making it easier to manage and maintain consistent configurations across multiple servers and environments.
It uses a declarative language called Chef DSL (Domain-Specific Language) to define the desired state of resources and systems.
Chef Solo
Chef also offers a standalone mode called Chef Solo, which does not require a central Chef server.
Chef Solo allows for the local execution of cookbooks and recipes on individual systems without the need for a server-client setup.
Benefits of Infrastructure as Code Tools
Infrastructure as Code (IaC) tools offer numerous benefits that contribute to efficient, scalable, and reliable infrastructure management.
IaC tools automate the provisioning, configuration, and management of infrastructure resources. This automation eliminates manual processes, reducing the potential for human error and increasing efficiency.
With IaC, infrastructure configurations are defined and deployed consistently across all environments. This ensures that infrastructure resources adhere to desired states and defined standards, leading to more reliable and predictable deployments.
IaC tools enable easy scalability by providing the ability to define infrastructure resources as code. Scaling up or down becomes a matter of modifying the code or configuration, allowing for rapid and flexible infrastructure adjustments to meet changing demands.
Infrastructure code can be stored and version-controlled using tools like Git. This enables collaboration among team members, tracking of changes, and easy rollbacks to previous configurations if needed.
Infrastructure code can be structured into reusable components, modules, or templates. These components can be shared across projects and environments, promoting code reusability, reducing duplication, and speeding up infrastructure deployment.
Infrastructure as Code tools automate the provisioning and deployment processes, significantly reducing the time required to set up and configure infrastructure resources. This leads to faster application deployment and delivery cycles.
Infrastructure as Code tools provide an audit trail of infrastructure changes, making it easier to track and document modifications. They also assist in achieving compliance by enforcing predefined policies and standards in infrastructure configurations.
Infrastructure code can be used to recreate and recover infrastructure quickly in the event of a disaster. By treating infrastructure as code, organizations can easily reproduce entire environments, reducing downtime and improving disaster recovery capabilities.
IaC tools abstract infrastructure configurations from specific cloud providers, allowing for portability across multiple cloud platforms. This flexibility enables organizations to leverage different cloud services based on specific requirements or to migrate between cloud providers easily.
Infrastructure as Code tools provide visibility into infrastructure resources and their associated costs. This visibility enables organizations to optimize resource allocation, identify unused or underutilized resources, and make informed decisions for cost optimization.
