Abstract: A security management method of Internet of blended environment (IoBE) in which a plurality of environments are connected to each other through a network includes: detecting a security anomaly occurring through an attack surface existing in a device included in each of the plurality of environments in the IoBE or in a network connection section between the plurality of environments; collecting attack data related to the detected security anomaly, and analyzing an attack type based on the collected data; dynamically combining response techniques based on the analyzed attack type; and performing an automatic response to the security anomaly based on the combined response techniques.
