Definition. Scanning identifies live hosts and running services . Enumeration probes the identified services more fully for known weaknesses . Enumeration is more intrusive, using active connections and directed queries. Erkki. . Makinen. University of . Tempere. . Tempere. , Finland. Margareta Ackerman. University of Waterloo.

Since DFA are equivalent with NFA. ε. , in order to show that L is regular it suffices to construct an NFA. ε. . that recognizes L.. A Small Census. NOTE: .
