Standard defenses are powerless against zero-day threats
Zero-day attacks are cyber attacks against software flaws that are
unknown and have no patch or fix.
It’s extremely difficult to detect zero-day attacks, especially with
traditional cyber defenses. Traditional security measures focus on
malware signatures and URL reputation. However, with zero-day attacks,
this information is, by definition, unknown. Cyber attackers are
extraordinarily skilled, and their malware can go undetected on
systems for months, and even years, giving them plenty of time to
cause irreparable harm.
Based on recently discovered types of zero-day attacks, it has
become apparent that operating system level protection is becoming
less effective, watering hole attacks are becoming more common, and
cyber attacks are becoming more sophisticated and better at bypassing
