The Importance of DevOps Security in 2023
DevOps and cybersecurity are quickly becoming the pillars of the IT industry. Everything is
going digital as the digital transformation wave disrupts sectors and creates new efficiencies. But
security concerns are also on the rise. Software development and deployment processes are often
subject to cyber-attacks. Thus, a new concept called DevSecOps, or DevOps security, is gaining
popularity.
This article explains what DevOps security is, how it works, its challenges, and its importance
for your IT company. But first, let’s discuss what DevOps is.
What is DevOps?
DevOps refers to a set of cultural practices and philosophies that bring together the software
development (Dev) and operations (Ops) teams to shorten the development cycle. It also offers
continuous delivery while maintaining the high quality of the software.
DevOps has gained popularity because it enables you to make updates to the application and fix
bugs frequently. Thus, continuous integration of CI and CD are the hallmarks of the DevOps
model.
It automates the build and delivery process of software applications. Usually, these applications
are made up of multiple microservices and are typically deployed in the cloud and containerized
environments.
The DevOps model, when used with cloud-based elastic infrastructure, has the capability to meet
a rise in demand by auto-scaling its processes. It enables the DevOps teams to offer new
computing resources (containers/virtual machines, etc.) and deploy additional application
instances on a needs basis.
What is DevOps Security?
Despite the many business benefits of DevOps, the model is vulnerable to security breaches.
Ensuring application security is a challenging task. For example, a DevOps model increases the
number of automated processes. It also builds and deploys applications using the microservices

architecture and containers. Not only that, but it also uses a wide array of tools and code
repositories.
Thus, many tools, services, and applications need to be secured while using the DevOps model
for application development. This is not the case with traditional development methodologies,
which don’t use such a wide variety of tools, etc. Hence, a DevOps model requires stringent
security measures to develop and deploy secure applications at scale.
DevOps security is actually an extension of DevOps. DevSecOps is short for development
(Dev), security (Sec), and operations (Ops). DevOps security puts the concept of software
security at the center of the app development process. It calls for making security a key
component of the software development pipelines.
DevOps services has genuinely revolutionized the software development lifecycle. Companies
now focus on the agility to provide microservices applications as opposed to monolithic
applications. Thus, security needs to be adequately integrated into the development and
operational processes of the company.
The DevOps security approach offers a secure development environment that defines security
patterns for applications and services built and deployed. It also automates security for processes
that have been automated.
Challenges of Securing the DevOps Model
DevOps services offers new capabilities to IT companies. But it also presents unique challenges.
Since DevOps is more of a cultural change and a shift in attitude, its security risks are also
nuanced. Traditional security management tools often fall short of addressing these security
concerns.
Here are some of the challenges the DevOps security model faces.
High-level Threat to Privileged Credentials

Privileged access management faces the highest level of threat in a DevOps environment.
DevOps processes are run on human and machine-privileged credentials. These credentials are
always a target for attackers since they yield the greatest leverage to them.
Machine access refers to tools and machines that need permission to access sensitive resources
without human intervention. Examples include automation tools (Puppet, Ansible); CI/CD tools
(Jenkins, Azure DevOps); container management and orchestration tools (Docker, Kubernetes,
etc.).
If your privileged credentials are compromised, the attackers will gain access to sensitive
databases and CI/CD pipelines. They may even gain access to your company’s cloud
environment. Thus, it’s no surprise that attackers want access to this secret data – the privileged
credentials of a company. It leads to the destruction of your intellectual property, cryptojacking
of your devices, and loss of data.
Speed and not Security is the Focus of Developers
DevOps teams focus on building and delivering applications at high velocity. This often means
they overlook security concerns in their development pipelines by adopting insecure practices.
Examples include leaving credentials embedded in configuration files and applications. They
also include using new tools and third-party code that have not been adequately scrutinized for
security lapses. Moreover, developers hardly ever focus on securing their tools and infrastructure
from security breaches.
Using in-Built Features for Tool Security
Many DevOps tools offer in-built security features to keep the tool secure. These devops
services protect your sensitive data and company secrets. However, such in-built security
features hinder interoperability, as they don’t let you share secrets across tools, platforms, or
cloud environments.

However, the DevOps Services teams usually use these features for securing sensitive data. But
the problem is that these security features do not allow you to monitor and manage them
consistently, thus leading to security lapses and loss of data.
Let’s see how DevOps security works.
How DevOps Security Works
1. Implement Security Policy as Code – The concept of infrastructure as code is at the
heart of the DevOps model. It removes the need to configure and administer software
and servers manually. Apply this concept to your SDLC (software development
lifecycle) security policy to remove error-prone, manually intensive configuration
processes.
2. Separation of Duties – A DevOps team should have clearly defined roles and duties for
all its members. Therefore, developers should concentrate on designing applications that
fuel business growth. The operations team members should emphasize the provision of
reliable and scalable infrastructure. And last, security employees should emphasize
protecting assets and data and mitigating risks. Codify the interaction between each
department as a written security policy.
3. Integrate Security into CI/CD Pipelines – Sometimes, the DevOps Services treats
security as an afterthought. This means that it’s usually too late to implement security
changes once the software has been released to production. If you do want to implement
changes, it results in a delayed software release. Thus, modern management tools like
Kanban and advanced workflow scheduling are used to remove inefficiencies and
accelerate development. Moreover, focusing on microservices simplifies security
reviews and makes it easier to implement changes.
4. A Proactive Approach to Security – It is vital for you to place robust security
mechanisms in your software development lifecycle to mitigate risks, reduce
vulnerabilities, and strengthen the security posture. This entails addressing all your
SDLC security requirements comprehensively.

5. Automation – Just the way the DevOps model employs automation to remove human
latency and accelerate development, DevOps security should also use it to limit human
and manual interaction. Automating the security mechanisms enables you to
automatically rotate sensitive information, like passwords, keys, etc. Moreover, you can
quickly terminate privileged sessions and rotate passwords, etc., whenever a breach
occurs.
Other DevOps Security Measures
Here’s a list of other things you can do to implement DevOps security and ensure your SDLC is
fully secure.
 It would be best if you addressed any possible vulnerabilities and requirements in your
development pipelines to ensure high security.
 Ensure your code repositories are safe and secure by reducing the concentration of privilege for
building automation tools.
 Use the principle of least privilege. It ensures that only the relevant machines and employees
have access to the required resources.
 Keep sensitive information (passwords, keys, etc.) in a highly secure vault that is accessible
when needed.
 Rotate company secrets like keys and passwords to mitigate the risk of exposure.
 Define a baseline for normal behavior so that any abnormality or anomaly raises a red flag.
 Give each machine a unique identifier to monitor its activity and access sensitive data.
 Train and educate your team on evolving cyber threats, vulnerabilities, and best practices.
 Encourage collaboration between team members.
Conclusion
As the world increasingly becomes tech-enabled, the power and importance of software will
grow exponentially. IT companies are compelled to deliver innovative, highly scalable, and
secure applications at high velocity. These market dynamics often push DevOps teams to focus
on speed, not security.
However, cybersecurity is also evolving rapidly. New tools and technologies are being used to
target sensitive business data. In view of this, it is crucial for companies to instill robust security
mechanisms in their software development lifecycles. DevOps security, or DevSecOps, is the
best way to ensure that you are able to deliver incredible and highly secure software apps at
scale.
