Managing vulnerabilities in an ever-evolving technical environment is a daunting task. Vulnerabilities pop up regularly, but not all vulnerabilities present the same level of risk. Traditional metrics such as CVSS scores and vulnerability counts are inadequate for effective vulnerability management because they lack business context, prioritization, and understanding of attacker opportunities. Vulnerabilities are only a small part of the attack surface available to attackers.
Initially, organizations used manual methods to address known security weaknesses, but as technology and cyber threats evolved, a more automated and comprehensive approach was required. , traditional vulnerability management tools were designed primarily for compliance, and modern tools still face challenges of prioritization and limited resources, especially in dynamic and agile cloud environments. increase.
Modern vulnerability management integrates security tools such as scanners, threat intelligence, and remediation workflows to deliver more efficient and effective solutions. Nevertheless, organizations continue to face challenges such as:
- A growing list of vulnerabilities
- Inaccurate Prioritization
- Missing business context
- Mismatched priorities and resources between IT and security teams
- A Unified View of Lack of Coverage and Risk
Exposure is broader than a typical CVE and can include more than just vulnerabilities. Exposure can be caused by many factors, including human error, poorly defined security controls, and poorly designed and insecure architectures. Many security tools tend to focus on specific types of exposures, such as vulnerabilities, misconfigurations, and identities, and address each separately. However, this approach does not take into account how attackers see networks and systems. Attackers don’t look at individual exposures. toxic combination Eliminate vulnerabilities, misconfigurations, overly permissive identities, and other security gaps to navigate between systems and reach sensitive assets. This route is called an attack path, and this type of lateral movement can go undetected for weeks or months, allowing an attacker to inflict significant and lasting damage while hiding within the network. increase.
A modern exposure management program combines multiple exposures into an attack graph to understand the relationship and context of risk to critical assets. This enables targeted remediation that reduces risk in the most cost-effective manner.to build the State-of-the-art exposure control programthe organization recognizes the evolution of threat actors and their tactics, establishes operational processes to ensure continuous security posture improvement, and implements plans consisting of remediation plans, remediation reviews, risk mitigation and mitigation verification. need to do it.
At XM Cyber, we believe that only by combining multiple exposures into an attack graph that visualizes all possible attack paths can we understand the relationship and context of risk to critical assets. Also, understanding the context allows you to accurately prioritize issues and focus on the exposures that need fixing. choke pointThis allows for productive remediation that reduces risk in the most cost-effective manner.
The three key pillars of building a modern exposure management program are:
- Understand Exposure Insights – Continuously identify and monitor potential risks to critical assets to identify gaps in security controls and deviations from compliance standards.
- Attack Path Analysis – Create an attack graph view that visualizes all possible attack paths to your critical assets.
- Prioritize remediation efforts – Focus on the most critical issues and choke points that need immediate attention to reduce risk exposure in a cost-effective manner.
By combining these three pillars, organizations can build a comprehensive and effective exposure management program that helps protect critical assets and reduce overall risk exposure. This enables productive remediation that reduces risk in the most cost-effective manner. By continuously analyzing and monitoring exposures, organizations can build sustainable and scalable processes for managing risk over time.
