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 organizational defenses.
