5 reasons poor communication can sink DevSecOps

In the last few years, a major shift has occurred within the software industry in terms of how companies organize themselves and manage product responsibilities. The result is a merging of development and operations roles under a single umbrella known as DevOps. However, that’s not where the story ends. More and more businesses are beginning to realize that cybersecurity strategy should not be treated as an independent activity. Software reliability is completely dependent upon security and risk management; otherwise, you leave your organization vulnerable to external attacks.

The result of this thinking has been an increase in the scope of the DevOps role, adding a security aspect as well also known as DevSecOps. But not every company can easily shift to the DevSecOps model overnight, especially when communication issues get in the way. In this article, we'll cover five of the most common roadblocks and ways to avoid them.

1. Unclear responsibilities

Now that the DevSecOps trend has gone mainstream in the software industry, you'll see many new job listings popping up in this area. Unfortunately, some companies are using the term as a catch-all to throw various disconnected duties at a single person. The result can be quite frustrating.

Leadership and management need to set a clear scope for the responsibilities of DevSecOps engineers and integrate them directly with other parts of the organization, including development, quality assurance, and cloud administrators. DevSecOps can only work as a strategy if it's fully adopted and understood by people at every level.

It's also important to be careful not to characterize the DevSecOps concept as a group of tools. The focus should always remain on the individuals performing their duties and not the applications that they use. Clarifying this line of distinction can make it easier to communicate within your organization.

2. Missing connection to end-users

Engineers in the DevSecOps role should be involved at every phase of the software development lifecycle. Otherwise, they will not have a holistic view of the platform's security status and how it is functioning. In a worst-case scenario, the DevSecOps team is disconnected from end-users entirely.

If an engineer does not understand how real people are using their application, then the product as a whole is likely doomed. User requirements should form the basis of every coding project, and supporting the development lifecycle is only possible if that link exists and is maintained.

3. Too many (and unsecured) communication tools

Engineers in a DevSecOps role often spend the majority of their days coordinating between other groups within the organization. This activity can't succeed unless there is a strong communication tool set at their disposal. One mistake many companies make is deciding to invest in dozens of different chat, messaging, and conferencing apps in hopes that it will make things easier.

The problem is that easy online communication comes at the price of privacy. Some platforms retain your data for their own internal use or even to sell - in the form of uniquely identifiable IP addresses - to advertisers. Though it’s relatively easy to hide your IP address, do you want to trust an app that plays fast and loose with your information in the first place?

The problem is that all this ease of communication comes at a price which often includes data retention or sharing with third parties of uniquely identifiable information like IP addresses, which can be hidden a few different ways - but why trust an app that reveals it in the first place?

One way a DevSecOps team can address this issue is to emphasize the security risk to decision-makers in regards to many popular tools. Slack, WhatsApp, Snapchat and others are recent examples of a popular messaging apps that are now taking flak because of different security risks they pose. When it comes to email, even Gmail, the most popular email service, has been caught allowing unfettered access to user email addresses. Our advice is to use an encrypted email tool such as ProtonMail or Mailfence rather than rely on the usual suspects with with better name recognition.

The more communication tools you use, the larger the threat surface vulnerable to hackers.

4. Alert fatigue

One key part of the DevSecOps suite of responsibilities is to streamline all monitoring and alerting functions across the organization. The goal is to make it easy for both managers and engineers to find out about live issues and quickly navigate to the source of the problem.

In some cases, DevSecOps engineers will be asked to set very sensitive alerting protocols so that no potential problem is missed. There is a downside, though, because having too many notifications can lead to alert fatigue. This is especially true if your monitoring tools are throwing false positives all day long. A string of unnecessary alerts will cause people to stop paying attention to them.

An approach to alerting should be well thought out and clearly documented in runbooks by the DevSecOps team. A runbook should explain exactly what an alert means and the steps required to address it. This level of documentation allows DevSecOps engineers to outsource incident response to a larger group.

5. Hidden dependencies

Because of the wide scope of the DevSecOps role, sometimes organizations expect engineers to be fortune-tellers and be able to predict how changes will impact code, tests, security. This level of confidence cannot be reached unless there is clear and consistent communication across the company.

Take for example a decision to add a firewall protection around a database server to block outside threats. This will probably seem like a simple change for the engineers working on the system, but they may not realize that a new firewall could cut off connections to other services within the same infrastructure. If DevSecOps was involved in the meetings and decision making, then this type of hidden dependency could have been uncovered earlier.

The DevSecOps model can only succeed if the organization has a strong policy of change management. Any modification to a live system should be thoroughly vetted by representatives of all teams. At that time, risks can be weighed and approvals can be made. Changes should be scheduled at times when the impact will be minimal.

Final thoughts

When browsing job listings, you'll surely see an influx of roles mentioning both DevOps and DevSecOps. These roles can have an incredibly wide scope and often play a critical role in the success of a software company. But breakdowns in communication have the potential to derail the goals of DevSecOps putting the entire organization at risk.

Modern software development is all about being agile, meaning that requirements gathering and coding all happen with great flexibility and fluidity. The same should be true for DevSecOps. The duties of this role should be evaluated and tweaked on a regular basis and clear communication is the best way to go about it.
