Understanding the Security Posture

DevSecOps is one area that is having an all-time boom for organizations. Alternatively, we can say that DevSecOps is an increasingly critical area for organizations. Every organization wants to move toward or shift toward using DevSecOps processes, tools, and technologies. The immense changes in the applications and the code led to a big change in the way we used to work with the code. Stakeholders want to have new functionalities and features with lightning speed. However, while we are shifting gears toward DevSecOps, we need to look at a big horizon. While transitioning to a cloud-native approach offers advantages, it also introduces significant risks.

The way we are adopting with lightning-fast speed, we are missing out on understanding what goes into designing a secure environment, and now, we are talking about the Internet of Things (IoT), Operational Technology (OT), and dependencies, it becomes imperative to understand the ecosystem very...

Understanding your security posture

In DevSecOps, posture management focuses on identifying security issues and addressing unresolved concerns early:

• The development pipeline is an automated process that facilitates code deployment to production
• Within the deployment pipeline, we have steps defined to perform the actions to reach the production stage
• Development pipeline needs to be secured by understanding the right posture. This means the tools, technologies, and people involved
• It entails understanding any associated third-party vendors or risks from the vendor

Regular meetings

DevSecOps pipelines are automated, but regular meetings among team members are essential for alignment and collaboration. Having a regular cadence to know where we stand and to make sure we are on the right path is important to be on top of things and the development pipeline. At the same time, it is important to understand where to stop and change gears. You can’t move...

Why and what measures we take to secure the environment

Posture management helps in securing our DevSecOps environment. It helps in evaluating the issues that can happen in the development pipeline. It also emphasizes monitoring applications.

It’s essential to continuously audit the DevOps pipeline to identify potential vulnerabilities, misconfigurations, or human errors. Pipelines can also be measured, and as much automation can be done as possible. It can give us a glimpse of the DevSecOps posture and the risks associated with it from a bird’s-eye view. Understanding this will help us understand the threats and risk exposure for the application or software.

Building the vulnerabilities inventory

The inventory of vulnerabilities, also known as the artifactory, can be a gold mine in terms of vulnerabilities. Vulnerabilities from all sources need to be kept in one place for better tracking.

Addressing vulnerabilities

It is important to fix vulnerabilities...

What measures can we take to monitor an environment?

Mapping posture management to the organization’s strategy involves integrating security considerations and measures into the broader strategic planning and execution process within the organization.

Think of your organization as a castle. The organization’s strategy is like the blueprint for building and expanding the castle, while security posture management is like the plans for the castle’s defenses – its walls, gates, guards, and watchtowers. Just as a castle’s defenses need to be built with its layout and expansion plans in mind, your organization’s security measures need to be aligned with its strategic objectives.

This means that when you’re laying out the strategy for your organization – maybe you’re planning to launch a new online service, or you’re looking to store more customer data – you need to consider how these moves will impact your...

Where does security stand in the whole development process?

Any unaddressed vulnerability can be exploited, emphasizing the need for proactive security measures in the DevSecOps process. Attaining a 360-degree posture results in asking questions about the following aspects:

• What reliance do they have?
• Are they internal or exposed applications?
• Are all stakeholders involved?
• Who has ownership of the data and its vulnerabilities?
• What code commits and repositories are available?

Compliance and audit

Compliance is one area that needs to be looked upon with utmost importance. It brings together all the technologies and stitches together the pieces that can be missed if they’re not considered. Compliance has always been one area we must consider to be in the market or to show we are on par. However, a unified view of the environments, roles, and susceptibilities alongside meeting the right compliance is important. The same approach should be followed...

Summary

Wrapping up this chapter, let’s take a step back and look at the big picture. When we talk about security posture management, it’s not just some technical jargon that’s reserved for the IT department. No, it’s much more than that – it’s about the safety and integrity of the whole organization in this digital age, where threats could emerge from any corner of the internet.

What we’ve learned from this chapter is that security posture management is like an ongoing journey, not a destination. It’s not something you set and forget. It’s a continuous commitment that needs consistent attention, effort, and resources. You can’t just check a few boxes, install some software, and call it a day.

Let’s revisit the main stages of this journey: risk management, vulnerability management, creating sound security policies, and staying vigilant through continuous monitoring. All of these steps weave together...
