Network Quota
An attacker may try to overload a server in your network by establishing a very large
number of connections per second. To protect against Denial Of Service (DoS) attacks,
Network Quota enforces a limit upon the number of connections per second that are
allowed from the same source IP address.
You can configure how connections that exceed that limit should be handled.

• None. No action.
Track Specify whether to log connections from a specific source that exceed
the Max. Connections/Second per Source IP threshold, by selecting one of
the following:
• Log. Log the connections. This is the default.
• None. Do not log the connections.
