It's beneficial for tasks where you want AI to make predictions or classifications based on past data, like identifying spam emails or estimating real estate prices. Unsupervised learning Imagine sending an AI on an exploration mission into a dense jungle, where the data is the unexplored forest. Just as an explorer observes and...

Challenge Handshake Authentication Protocol (CHAP) is a challenge-response identity authentication protocol.

It requires both entities to prove their identity through a cryptographic exchange or a “three-way handshake”. When that is successful, authentication is complete ...

This flaw can be in software programs, operating systems, hardware devices, connected services, IoT devices, and more. When exploited by a hacker, these weaknesses can cause major problems for individuals and large corporations...

Kerberos is a passwordless computer network security authentication protocol that was created by MIT to help solve network security problems.

Like many programming languages, structured query language (SQL) is vulnerable to manipulation and abuse by hackers.

Ransomware-as-a-Service (RaaS) is a fairly new threat in cybersecurity.
