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:
“The Dada object reflected an ironic posture before the consecrated forms of art. The surrealist object differs significantly in this respect. It stands for a mysterious relationship with the outer world established by man’s sensibility in a way that involves concrete forms in projecting the artist’s inner model.”
—J.H. Matthews. “Object Lessons,” The Imagery of Surrealism, Syracuse University Press (1977)
“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)
