Agent-less Posture Assessment
Most NAC vendors require the 802.1x supplicant (client or agent) to be installed. Some, including Netclarity, Trustwave, and Enterasys offer an agent-less posture checking. This is designed to handle the "Bring Your Own Device" or "BYOD" scenario to:
- Detect and fingerprint all network attached devices, whether wired or wireless
- Determine if these devices have common vulnerabilities and exposures (aka "CVEs")
- Quarantine rogue devices as well as those infected with new malware
The agent-less approach works heterogenously across almost all network environments and with all network device types.

Famous quotes containing the words posture and/or assessment:
“If one’s posture is upright, one has no need to fear a crooked shadow.”
—Chinese proverb.
“The first year was critical to my assessment of myself as a person. It forced me to realize that, like being married, having children is not an end in itself. You don’t at last arrive at being a parent and suddenly feel satisfied and joyful. It is a constantly reopening adventure.”
—Anonymous Mother. From the Boston Women’s Health Book Collection. Quoted in The Joys of Having a Child, by Bill and Gloria Adler (1993)
