Continuous monitoring is a process of collecting and analyzing data on the performance and security of third-party vendors on an ongoing basis. Continuous monitoring helps to identify and mitigate potential risks, such as data breaches, credential exposures, insider fraud/theft, and other cyber incidents, that may affect the organization and its customers. Continuous monitoring can use various techniques, such as monitoring surface, vulnerabilities, passive and active indicators of compromise, and business intelligence.

Passive and active indicators of compromise are examples of continuous monitoring techniques that track the signs of malicious activity or compromise on the third-party vendor’s systems or networks. Passive indicators of compromise are data sources that do not require direct interaction with the target, such as threat intelligence feeds, dark web monitoring, or external scanning. Active indicators of compromise are data sources that require direct interaction with the target, such as penetration testing, malware analysis, or incident response. Both passive and active indicators of compromise can provide valuable information on the current state and potential threats of the third-party vendor’s environment.

The other options are not examples of continuous monitoring techniques that track breach, credential exposure and insider fraud/theft alerts. Monitoring surface is a technique that measures the size and complexity of the third-party vendor’s attack surface, such as the number and type of internet-facing assets, domains, and services. Vulnerabilities are a technique that identifies the weaknesses or flaws in the third-party vendor’s systems or applications that can be exploited by attackers, such as outdated software, misconfigurations, or unpatched bugs. Business intelligence is a technique that analyzes the business performance and reputation of the third-party vendor, such as financial stability, customer satisfaction, or regulatory compliance. References:
