With the rising innovative antigens (such as intruders and viruses) through
Internet, reliable security mechanisms are required to perceptively detect
and put them down. However, defense techniques of the current host system
over Internet may not properly analyze Internet antigens, because trends of
attacks are unexpectedly shifted. In this paper, we introduce an Antibody
Layer that mediates proper security services based on the biological mechan
ism to rapidly disclose and remove innovative antigens. The proposed Antibo
dy Layer also employs a new topology called antibody cooperation protocol t
o support real-time security QoS for one host as well as host alliance.
