# Communication best practices
<a name="communication-best-practices"></a>

 Effective communication accelerates incident resolution. Follow these practices when working with AWS Security Incident Response engineers: 
+  **Respond promptly** to information requests from your Security Incident Response engineer 
+  **Provide complete information** even if you're uncertain about its relevance 
+  **Ask questions** if you don't understand a recommendation or need clarification 
+  **Update the case** with any new developments or changes to the incident 
+  **Designate a primary contact** from your team to coordinate with Security Incident Response engineers 

**Important**  
 If AWS Security Incident Response engineers don't receive a response to critical information requests within 5 business days, we work toward case closure. You can reopen a case if new information becomes available.
