Fix Recommendation

Configure the Nokia router to protect against or limit the effects of all known types of DoS attacks by employing organization-defined security safeguards.

Configure Distributed CPU Protection to rate limit various core/peering protocols, Link, ESM, interface protocols, and any other unspecified control traffic, as shown in the example below:

- configure system security dist-cpu-protection policy <policy name> create
- static-policer <name> create
- rate packets <ppi| ma> within <seconds>
OR
- rate kbps <kbps | max> bytes mbs <size>
- exceed-action discard
- back
- protocol <protocol name or all-unspecified> create

Apply the policy to each interface:

- configure router inter <interface name> dist-cpu-protection <policy name>

Check Contents

Determine if the Nokia router protects against or limits the effects of all known types of DoS attacks by employing organization-defined security safeguards.

Verify Distributed CPU Protection is configured for each interface, as shown in the example below:

- show router interface detail | match OperDCpuProtPlcy
OperDCpuProtPlcy : test
OperDCpuProtPlcy : ssh

If the Nokia router does not protect against or limit the effects of all known types of DoS attacks by employing organization-defined security safeguards, this is a finding.
