Group -
The Cisco perimeter switch must be configured to suppress Router Advertisements on all external IPv6-enabled interfaces.
Many of the known attacks in stateless autoconfiguration are defined in RFC 3756 were present in IPv4 ARP attacks. To mitigate these vulnerabilities, links that have no hosts connected such as the ...Rule Medium Severity -
SRG-NET-000364-RTR-000200
Group -
The Cisco perimeter switch must be configured to drop IPv6 undetermined transport packets.
One of the fragmentation weaknesses known in IPv6 is the undetermined transport packet. This packet contains an undetermined protocol due to fragmentation. Depending on the length of the IPv6 exten...Rule Medium Severity -
SRG-NET-000364-RTR-000201
Group -
The Cisco perimeter switch must be configured drop IPv6 packets with a Routing Header type 0, 1, or 3-255.
The routing header can be used maliciously to send a packet through a path where less robust security is in place, rather than through the presumably preferred path of routing protocols. Use of the...Rule Medium Severity -
SRG-NET-000364-RTR-000202
Group -
The Cisco perimeter switch must be configured to drop IPv6 packets containing a Hop-by-Hop header with invalid option type values.
These options are intended to be for the Destination Options header only. The optional and extensible natures of the IPv6 extension headers require higher scrutiny since many implementations do not...Rule Medium Severity -
