SMTP IPS/FW

• Click the 'Modules' tab > 'SMTP IPS/FW'.

• Secure Email Gateway's SMTP Intrusion Prevention System (IPS) and Firewall (FW) module provide protection against Denial of Service (DoS) and SYN attacks.

• SYN attacks are dealt with using SYN Cookies and SYN Cache features.

• DoS attacks are blocked by deploying various usage limitations.

• For example, Secure Email Gateway can limit the number of connections it accepts in a certain time-period. The IPS/FW module will block IPs that want make more connections more than the limit. You can specify the limit in a security profile.

• The module also lets you create whitelist and block rules to better control spam. The rate control feature, a subset of the DoS protection system, allows you to control how many connections are allowed within the specified time from the same IP address.
