Achieving a Successful Continuous Threat Exposure Management Program

Written by Lydia Zhang, the President and Co-founder of Ridge Security

If your organization is concerned about increasing and expanding cyber threats, you are not alone. While many enterprises recognize the need to create a multi-layered security posture, this article explores the importance of Continuous Threat Exposure Management (CTEM) and how it can help proactively manage risks and bolster defences against growing cyber threats.

CTEM is a cybersecurity program that goes beyond simply responding to threats. It leverages proactive attack testing and simulation to identify and mitigate vulnerabilities before real attackers exploit them. Organizations can prioritize and allocate resources more effectively by continuously monitoring and evaluating security risks. This systematic approach allows for a more robust defence in the face of a rapidly expanding attack surface.

Primary Benefits of Implementing a CTEM Program
Let’s take a closer look at some of the key advantages of implementing CTEM. By continuously scanning and monitoring your digital infrastructure, you can proactively stay one step ahead of cyber threats. CTEM prioritizes threats based on their potential impact and likelihood of occurrence. This way, resources can be efficiently allocated to tackle the most significant risks first. By following an iterative approach, CTEM allows you to learn from each assessment and adapt defences accordingly. You can implement effective remediation measures and continuously improve your security posture by generating actionable insights from real-time threat data.

This data-driven approach ensures decisions are made based on the latest threat intelligence. This empowers security teams to make more targeted and effective remediation efforts by leveraging real-time data. To maximize the effectiveness of a CTEM program it must be aligned with the organization’s business objectives. This also helps achieve adaptability and continuous protection against the ever-evolving threat landscape. By incorporating your strategic business goals into the CTEM program, you can ensure that it works hand-in-hand with your overall cybersecurity strategy.

The Lifecycle Process of an Effective CTEM Program
A successful CTEM program follows a comprehensive lifecycle process. Let’s break it down into key steps. In the initial phase, the security team identifies and analyzes the infrastructure assets to be included in the program. This analysis encompasses both internal and external attack surfaces, including on-premises and multi-cloud infrastructures.

Each asset’s risk profile is evaluated, covering explicit vulnerabilities and weaknesses like misconfigurations. Understanding the potential impact of vulnerabilities on business operations is essential. Gaps in the security infrastructure are identified, such as logging and detection gaps, and missing, fragmented, meaningless detection rules.

Cybersecurity capabilities, such as automated pen-testing, controlled attack simulation, and adversary emulation, are carried out within DevOps and production environments. These activities verify cybersecurity weak points and assess the effectiveness of your remediation efforts. Automation plays a crucial role in the CTEM process. It enables organizations to continuously identify, prioritize, validate, and address vulnerabilities and threats. By leveraging automation, you can stay ahead of the evolving threat landscape and constantly improve your security posture.

How to Tell If Your CTEM Program Is Working
Once you have a CTEM program, how do you know if it’s making a difference? There are some key indicators that can help measure the success of your CTEM program.

The first and most obvious sign of a successful CTEM program is decreased security risks. You want to see fewer vulnerabilities popping up, and when they do, you want faster resolutions. You also want to see a drop in successful attacks or breaches. In this cyber game of cat and mouse — your CTEM program should be the cat!

An effective CTEM program will see an improvement in your ability to detect bad actors trying to disrupt systems. It’s not just about quantity; you also want to see the increased complexity of threats detected. After all, cybercriminals are constantly evolving, so your CTEM program needs to keep up!

Time is of the essence when it comes to cybersecurity. A successful CTEM program should help you reduce the time between discovering and fixing a threat. The quicker you respond, the less damage, so keep an eye on how fast you’re remedying those vulnerabilities.

Automated pen-testing, workflow segmentation and Breach and Attack Simulation are ways of measuring how well your security controls are performing. You want to see those controls becoming more effective over time. It’s training your defences to be stronger and smarter.

Compliance is essential if you’re in an industry with regulatory requirements. A successful CTEM program should help you meet and maintain those compliance standards. So, pay attention to any decrease in compliance violations or issues. It’s a good sign that your program is on the right track.

Now that you know how to assess the success of your CTEM program, keep an eye on these indicators, and remember, it’s all about reducing risks, improving threat detection, responding faster, enhancing security controls, staying compliant, and protecting what matters most to your business.
