Description
Manipulation of IP addresses can allow untrusted systems to appear as trusted hosts, bypassing firewall and other security mechanism and resulting in system penetration.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Determine the zone that you are currently securing. # zonename If the command output is "global", then only the "phys" and "SR-IOV" interfaces assigned to the global zone require inspection. If using a non-Global zone, then all "phys" and "SR-IOV" interfaces assigned to the zone require inspection. Identify if this system has physical interfaces. # dladm show-link -Z | grep -v vnic LINK ZONE CLASS MTU STATE OVER net0 global phys 1500 unknown -- e1000g0 global phys 1500 up -- e1000g1 global phys 1500 up -- zoneD/net2 zoneD iptun 65515 up -- If "phys" appears in the third column, then the interface is physical. For each physical interface, determine if the network interface is Ethernet or InfiniBand: # dladm show-phys [interface name] LINK MEDIA STATE SPEED DUPLEX DEVICE [name] Ethernet unknown 0 half dnet0 The second column indicates either "Ethernet" or "Infiniband".

For each interface, determine if the host is using SR-IOV’s Virtual Function (VF) driver: # dladm show-phys [interface name] | grep vf If the sixth column includes 'vf' in its name, it is using SR-IOV (ex: ixgbevf0).

If the interface uses ip-forwarding and if mac-nospoof, restricted, and dhcp-nospoof do not appear in the "VALUE" column, this is a finding. If the interface uses SR-IOV and if mac-nospoof, restricted, and dhcp-nospoof do not appear in the "VALUE" column, this is a finding.

Determine the name of the zone that you are currently securing. # zonename If the command output is "global", then only the "phys" and "SR-IOV" interfaces assigned to the global zone require configuration. If using a non-Global zone, then all "phys" and "SR-IOV" interfaces assigned to the zone require configuration. The Network Link Security profile is required. Determine which network interfaces are available and what protection modes are enabled and required. Enable link protection based on each configured network interface type. For InfiniBand: # pfexec dladm set-linkprop -p protection=restricted,ip-nospoof,dhcp-nospoof [interface name] For IP forwarding: # pfexec dladm set-linkprop -p protection=mac-nospoof,restricted,dhcp-nospoof [interface name] For SR-IOV: # pfexec dladm set-linkprop -p protection=mac-nospoof,restricted,dhcp-nospoof [interface name] For Ethernet without IP forwarding: # pfexec dladm set-linkprop -p protection=mac-nospoof,restricted,ip-nospoof,dhcp-nospoof [interface name]
