While this is the "traditional" approach, "all" may be an overstatement.
Several antivirus/antimalware solutions include a "heuristic" component
which can, if not *prevent* an attack, alert you that an application's
behavior is deviating from reasonable expectations.
Of course, an attack detected this way needn't be a zero-day. But since
the detection is not based on recognizing a known attack signature, it can
work as well on unknown attacks as on known ones.
