Managed Security Services
Branch Gateway IP interfaces and gateway applications such as WAN routers, PoE switches,
and VPN devices can be at risk for DoS attacks. The Branch Gateway identifies predefined or
custom-defined traffic patterns as suspected attacks and generates SNMP notifications,
referred to as Managed Security Services (MSS) notifications.

MSS notifications are sent to the active MGC by the dynamic trap manager. MSS notifications
sent to the active MGC by the dynamic trap manager are converted to syslog messages by
the SNMP trap manager on the MGC. For general information about configuring and enabling
