Advanced Persistent Threat (APT)
A prolonged and targeted cyberattack in which an intruder gains access to a network and remains undetected for an extended period.
Understanding APTs
APTs represent a complex and evolving threat in cybersecurity, characterized by their persistence, sophistication, and strategic targeting. Unlike conventional cyber attacks, APTs involve long-term campaigns with specific objectives, often focusing on high-value targets such as government agencies, defense contractors, or large corporations.
