Integrating cyberthreat intelligence (CTI) into a DevOps platform is critical to prevent, detect, respond, and predict cybersecurity threats in a more timely and cost-effective manner. This is true because integration allows automation of everyday tasks such as patch management and vulnerability scanning, allowing employees to turn their attention away from these automated tasks to focus on more complex problems and analyses.
At the same time, in our modern, complicated, fast-paced cyber environment, it's difficult to hunt for and find vulnerabilities. Ideally, you will subscribe to threat feeds that have information specific to your systems, networks, or industry, because a power plant operator will want different kinds of threat information than a bank IT team. If your threat feed is specific to your environment, it could help automate the discovery of vulnerabilities and help you prioritize fixes. If you get a threat alert about a specific application you are running and you have information about how to remediate, it's more likely you can create an automated task to fix the vulnerability.
This automation of threat intelligence creates several benefits for an organization, such as the following:
- Reducing the mean time to discovery of vulnerabilities and subsequent recovery.
- More quickly lowering risk in your organization's overall security posture, which allows for quicker response to vulnerabilities or attacks
- Preventing attackers from repeating attacks
Other areas where automation can provide value beyond vulnerable applications include:
- Automatically feeding information to dashboards and reports
- Removing bottlenecks so that your changes process more intelligently and faster
- Reducing errors in DevOps systems configurations
Are You Properly Integrating CTI?
To determine if your organization is integrating cyberthreat intelligence in a valuable way, consider this checklist:
- Do you have real-time threat intelligence data feeds? Are you using a threat intelligence platform?
- Can you glean intelligent courses of action from your intelligence feed?
- Are you proactively sharing your intelligence with other business units in your organization, at a minimum?
- Are your analysts more efficient in that they aren't spending hours reading PDFs and emails?
- Are you able to measure the time to respond and show it's decreasing?
- Have you prevented the same attacks/malware from being repeated against various parts of your enterprise network?
If the answer to any of these questions is no, your organization is leaving a lot on the table.
How Do You Create Cyberthreat Intelligence Integration?
The benefits are clear, and you've determined that your organization could improve CTI. What's next?
First, the basic requirements. You'll need a decent pipeline to start with by leveraging a continuous integration server (Jenkins is a good example). You'll also need a configuration management server (such as Chef). The requirements list also contains miscellaneous items such as central logging, a central vulnerability scanning system, and firewall management (or the ability to control your infrastructure using something like Terraform). You'll need a minimum of one threat feed — more if you can spare it — coming into your infrastructure in a central place. These basic requirements will all come together to create your threat intelligence platform (TIP).

Now that the pieces are in place, you'll need to stick it all together with glue. You'll need a way for your TIP to auto-review the threat feeds and trigger off of the ones that matter to your environment. For example, technology on your stack can identify threat campaigns against Amazon Web Services, where your critical operations are running. Then you'll need a way to plug in the recommended action.
If the recommended action is to upgrade a software component, then you can have your TIP tell your configuration management tool to upgrade the NGINX Web server to a version that's not vulnerable. Chef can then deploy and upgrade NGINX on your hosts.
And lastly, you'll want to ensure you've automatically opened a ticket in your issue tracker (such as Jira) to track the work. Include logs of the actions taken in both your issue tracker and to your central logging service.
The benefits of integrated cyberthreat intelligence are clear. Whether you're just getting your DevOps program started or are looking to bring an existing one into the 21st century, it's a critical component of future success.
