At its core, cyber threat exposure management (CTEM) is the culmination of traditional vulnerability management, threat intelligence, and attack surface management. In the past, organizations focused on identifying and patching software vulnerabilities, often with a reactive approach. CTEM is focused on proactively identifying all types of high-risk exposure that could leave your organization at risk, and empowering teams to proactively remediate them.

Today, the scope of cybersecurity threats has expanded enormously, extending beyond the traditional IT infrastructure to include cloud, operational technology, Internet of Things (IoT) devices, and even business processes.

At the same time, the threat landscape is undergoing rapid and disjunctive shifts. New threats such as stealer logs and triple extortion ransomware continue to proliferate leaving many security teams in a mode of constant reactivity.

CTEM aims to bridge the gap between these teams and enable cybersecurity teams to build a threat driven approach to cyber exposure management. 

Understanding the Concept of Cyber Exposure: A Detailed Overview

Cyber exposure refers to the quantifiable measure of an organization’s attack surface — the sum total of vulnerabilities that a threat actor can exploit in its:

  • External Network Assets (Company websites, web applications, cloud services, etc.)
  • External Brand Exposure (Social media, brand misuse, etc.)
  • Physical Assets (Offices, brick and mortar stores, etc.)
  • Third Parties 
  • Users 

This exposure encompasses not only known vulnerabilities but also previously undiscovered ones that may exist in the organization’s complex IT infrastructure. The greater an organization’s cyber exposure, the more likely it is to suffer a potentially catastrophic cyber attack.

Cyber exposure aims to address this widened threat landscape by providing a live view of the entire attack surface, including both digital and physical assets. It uses data to develop risk-based insights and visualizes cyber risk in the same manner that CFOs visualize financial risk. This enables an organization to make strategic decisions based on the potential business impact.

Understanding and managing cyber exposure is crucial in today’s hyper-connected world. It serves as the foundation for a proactive and risk-based approach to cybersecurity, ensuring organizations stay ahead of threats rather than merely responding to them. The next step in managing cyber exposure is implementing effective detection strategies.

As cyber threats grow more complex and numerous, detection strategies must evolve to match the pace. Implementing a robust, proactive approach to detecting cyber exposure is integral to a successful cybersecurity strategy. 

Here are some critical pillars of cyber exposure detection in the context of the modern threat landscape:

Comprehensive Visibility

The first step to managing cyber exposure is obtaining complete visibility of your entire IT ecosystem. This means identifying and cataloging all physical and digital assets, including:

  • Servers
  • Endpoints
  • Cloud-based applications
  • IoT devices

It’s essential to continuously monitor these assets to spot any changes or vulnerabilities that might increase your cyber exposure.

Vulnerability Assessment

After mapping out your digital landscape, the next step is assessing the vulnerabilities within your network and systems. This process includes identifying known vulnerabilities using databases like the Common Vulnerabilities and Exposures (CVE) system and conducting penetration testing to discover unknown vulnerabilities. 

It’s crucial to remember that new vulnerabilities can emerge at any time, necessitating a routine and ongoing assessment process.

Threat Intelligence

Cyber threat intelligence is a critical tool in the fight against cyber exposure. By keeping abreast of the latest threat trends, attacker tactics, and emerging vulnerabilities, organizations can stay one step ahead of potential attacks. 

Using a cyber threat intelligence platform can aid in automating this process, providing real-time alerts and in-depth analysis of the current threat landscape.

Risk Analysis

Identifying vulnerabilities is only part of the process; understanding the potential impact of these vulnerabilities is equally important. By performing a risk analysis, organizations can prioritize their remediation efforts based on the potential business impact of a vulnerability being exploited. This approach ensures that resources are allocated effectively, addressing the most critical threats first.

Incident Response

Detection strategies must be complemented by a robust incident response plan. When organizations detect a threat, they need to respond quickly to mitigate the damage. 

This requires having a pre-established incident response plan that includes:

  • Communication strategies
  • Roles and responsibilities
  • Procedures for containing and eliminating the threat

Incorporating these pillars into your cyber exposure detection strategy can significantly enhance your cybersecurity posture. However, while detection is vital, it’s only half of the equation. The other half lies in prevention strategies.

Prevention is Better than Cure: Best Practices to Mitigate Cyber Exposure

While detection is a critical component of managing cyber exposure, prevention is equally paramount. By implementing strategic preventive measures, organizations can significantly reduce their cyber exposure and mitigate potential risks. 

Here are some best practices to consider:

Regular Patching and Updating

One of the simplest ways to reduce cyber exposure is to regularly update and patch: 

  • Software
  • System
  • Applications

Many cyber attacks exploit known vulnerabilities in outdated software. Therefore, adhering to a regular patching schedule is essential.

Secure Configuration

Ensure all your systems and applications are configured securely. Default configurations can often leave organizations exposed to threats. By hardening these configurations based on industry best practices or guidelines like those provided by the Center for Internet Security (CIS), you can significantly reduce your attack surface.

Employee Training and Awareness

Human error remains one of the largest contributors to cyber exposure. Regular training and awareness programs can equip your employees with the knowledge to identify and avoid common threats like phishing attacks, thereby reducing the chance of a successful cyber attack.

Least Privilege Access Control

Implement a least privilege access control policy, which ensures that employees have only the access they need to perform their job. This minimizes the risk of internal threats and limits the potential damage in case of a breach.

Advanced Threat Protection Tools

Use advanced threat protection tools that leverage artificial intelligence and machine learning to proactively detect and prevent threats. These technologies can spot unusual patterns or behaviors that traditional tools might miss, helping to prevent attacks before they occur.

Incident Response Plan

While the focus here is on prevention, having a well-established incident response plan is still vital. It can help minimize the damage in the event of a security incident and ensure a swift return to normal operations.

Cybersecurity Culture

Foster a culture of cybersecurity within your organization. This goes beyond mere training; it means integrating cybersecurity into your organizational ethos and everyday practices.

Preventing cyber exposure is an ongoing, dynamic process that requires continuous attention and refinement. By proactively implementing these best practices, organizations can protect themselves against evolving cyber threats and significantly decrease their cyber exposure. The ultimate goal is to establish a resilient security posture that enables your business to thrive in the digital age.

Leveraging Cyber Threat Intelligence for Effective Cyber Exposure Management

In an age of escalating cyber threats, it is not enough to merely react to incidents. Organizations need to take a proactive stance to manage their cyber exposure effectively, and one of the key ways to do this is through leveraging cyber threat intelligence.

Cyber threat intelligence refers to the collection and analysis of information about potential or current attacks threatening an organization. By using this intelligence, organizations can better understand the risks and implications of cyber threats, allowing them to make informed decisions about their security strategy.

Here’s how cyber threat intelligence can be harnessed for effective cyber exposure management:

Proactive Threat Hunting

With detailed threat intelligence, your security team can proactively hunt for threats before they materialize into attacks. This involves searching for indications of malicious activities or anomalies within your networks that could signal a cyber threat. 

Early detection of these potential threats can help organizations remediate them swiftly, reducing their cyber exposure.

Prioritization of Threats

All threats are not created equal. Threat intelligence allows your organization to understand the potential impact and likelihood of different threats. With this understanding, you can prioritize your security efforts towards the most significant risks, ensuring efficient use of resources.

Strategic Decision Making

By providing an in-depth understanding of the threat landscape, cyber threat intelligence can guide strategic security decision making. It helps you identify trends, understand the tactics, techniques, and procedures (TTPs) of threat actors, and make predictions about future threats. 

This empowers your organization to stay one step ahead of cybercriminals and make strategic investments in your cybersecurity infrastructure.

Enhanced Incident Response

In the event of a security incident, cyber threat intelligence can provide valuable context, helping your incident response team understand the nature of the attack, the possible motivation of the attackers, and the potential implications. This leads to a faster and more effective response, minimizing damage and downtime.

Risk Management

At a broader level, cyber threat intelligence feeds into your organization’s overall risk management strategy. It aids in assessing your cyber risk, aligning your cybersecurity strategy with your business objectives, and demonstrating due diligence for compliance purposes.

In essence, cyber threat intelligence offers the foresight needed to anticipate and mitigate cyber threats.
