Why does having an EASM capability drastically improve your cybersecurity strategy?

Last year, 83% of cyber attacks emerged outside traditional security perimeters. Traditional, often internally-focused security defenses do not detect adversaries taking advantage of exposed internet-facing assets, which is leading to increasing frequency and impact of attacks. ZeroFox Attack Surface Management protects your external attack surface by identifying subdomains, IP addresses, software, security certificates, Shadow IT, and more to streamline the correlation and investigation of exposures for your known, unknown, and unmanaged assets exposed to the internet.

What is CVSS and how is it used?

The initial FIRST framework is the Common Vulnerability Scoring System (CVSS), a widely-used service that formally analyzes the technical characteristics of a vulnerability and provides a score (0-10) representing its severity. This scoring warns security teams of the worst-case impact they can expect from a particular vulnerability, based on its intrinsic characteristics and analyst and vendor findings.

What is EPSS and how is it used?

The second and newer FIRST framework, The Exploit Prediction Scoring System (EPSS) is a predictive model that combines technical information, vulnerability data, and threat intelligence to update scores. EPSS draws data from MITRE’s CVE List, CVSS base scores in the National Vulnerability Database, and vendor information. It also utilizes open-source threat intelligence, including exploit code from Metasploit, ExploitDB, GitHub, and public data from security scanners.

What is CISA KEV and how is it used?

CISA KEV stands for the Cybersecurity and Infrastructure Security Agency’s Known Exploited Vulnerabilities Catalog. It is a resource that lists vulnerabilities that are actively being exploited in the wild. The catalog aims to help organizations prioritize their patching and remediation efforts by highlighting vulnerabilities that pose a significant risk to their systems.

Your External Attack Surface is Bigger and Growing Faster Than You Think It Is

Externally exposed digital assets create a wide attack surface for cybercriminals. Yet most organizations are not fully aware of the constantly changing scope of their internet-facing assets and services. Are you effectively protecting your hidden digital cyber risks?

Common unmonitored and unmanaged exposures include:

forgotten cloud services
server misconfigurations
expired hostnames and weak certificates
abandoned development and demo projects
