All other DoS Prevention features are disabled by default.

Configuring DoS Prevention

The following pages are used to configure this feature.

Security Suite Settings

To configure DoS Prevention global settings and monitor SCT:

STEP 1

Click

Security

>

Denial of Service Prevention

>

Security Suite Settings

. The

Security Suite Settings

displays.

CPU Protection Mechanism: Enabled

indicates that SCT is enabled.

STEP 2

Click Details beside

CPU Utilization

to go to the CPU Utilization page and view

CPU resource utilization information.

STEP 3

Click

Edit

beside

TCP SYN Protection

to go to the SYN Protection page and

enable this feature.

SYN Protection

The network ports might be used by hackers to attack the device in a SYN attack,
which consumes TCP resources (buffers) and CPU power.

Since the CPU is protected using SCT, TCP traffic to the CPU is limited. However, if
one or more ports are attacked with a high rate of SYN packets, the CPU receives
only the attacker packets, thus creating Denial-of-Service.

When using the SYN protection feature, the CPU counts the SYN packets
ingressing from each network port to the CPU per second.

If the number is higher than the threshold, a SYSLOG message is generated, but
the packets are not blocked.

To configure SYN protection:

STEP 1

Click

Security

>

Denial of Service Prevention

>

SYN Protection

.

STEP 2

Enter the parameters.

•

Block SYN-FIN Packets

—Select to enable the feature. If TCP packets with

both SYN and FIN flags are detected, a SYSLOG message is generated.

•

SYN Protection Mode

—Select between three modes:
