Upgrade notes¶
Review the following search-time behavior changes before upgrading to version 1.8.0:
- GUI HTTP session-established events in
cisco:esa:httpnow map to Authentication through thecisco_esa_auth_logsevent type withaction=success. Previous releases mapped these events to Network Sessions Session_Start withaction=started. Thecisco_esa_http_sessionevent type was removed, so saved searches that reference this event type must be updated to usecisco_esa_auth_logs. - HTTP session-established events in
cisco:esa:system_logsnow map to Network Sessions Session_Start through thecisco_esa_network_sessions_startevent type. For these events,srcis populated from the initiating client IP extracted fromSourceIP. - Cisco ESA Network Traffic events now use application-specific
appvalues such ashttp,https, andSMTPinstead of the genericCisco Email Security Appliancevalue when the protocol is known. - System-generated Change events no longer synthesize
user_type=Userwhen there is no user context in the event.
