Hi @Pranali18 - Without knowing more specifics about your question, there is a helpful page in product documentation that discusses associating MITRE-ATT&CK information with security incidents here. This can be done manually or automatically from base system SIEM auto-extraction rules, detection rules, threat lookup results, observables, or child security incidents.
This diagram from the MITRE-ATT&CK framework overview in product docs also does a great job showing a high-level view of how MITRE-ATT&CK information flows through the Security Operations applications:
Let me know if you have any more specific questions about MITRE-ATT&CK.
