For customers who opt in, Cortex Xpanseperforms targeted scanning of known assets daily. Known Assets Monitoring (KAM) brings three significant benefits to the data delivered by Cortex Xpanse: * Additional ports and protocols * Port/protocol pairs not included in global scans, including port 25/SMTP, 500/UDP * SMB version enumeration * TLS/SSL scanning * Determination of supported cipher suites and protocol versions for TLS/SSL services * Frequent scanning and data delivery * Faster data delivery for reduced time to notification of new exposures ## **Opting in to Known Assets Monitoring** Note the following prerequisites for Known Assets Monitoring (KAM): * KAM uses more exhaustive payloads than global scans, so we recommend validating your network before opting in. KAM will be turned on once we have consent from the network owner that all identified ranges have been validated. * We recommend verifying that KAM source IP addresses are not blocked on your automated intrusion prevention system (IPS), intrusion detection system (IDS), or firewalls and that anti-scanning and DDoS rules do not apply to these specific IP ranges. * Cortex Xpanse scans your external attack surface only, so we do not need any access inside your network. * The amount of traffic you receive from our scanners depends on the KAM configuration (basic or extended) and the total amount of IP space owned by your organization. * Contact your Customer Success Team to learn more and opt in to KAM. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/cortex-xpanse/learn-about-cortex-xpanse/scanning/known-assets-monitoring.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
