What is an Advanced Persistent Threat (APT) in the context of cyber attacks on organizations?

An Advanced Persistent Threat (APT) is a type of cyber attack where hackers gain unauthorized access to a network and remain undetected for a long period, continuously extracting confidential information.

What is a Denial of Service (DoS) attack?

A Denial of Service (DoS) attack is an attempt to make a network or service unavailable by overwhelming it with a flood of traffic, preventing legitimate users from accessing it.

What is a Distributed Denial of Service (DDoS) attack?

A Distributed Denial of Service (DDoS) attack is a type of DoS attack where multiple systems are used to generate a large volume of traffic to overwhelm the target, making it unavailable to its intended users.

What is a SQL Injection attack?

A SQL Injection attack is a type of cyber attack where a hacker manipulates a standard SQL query in a database-driven website, allowing them to view, edit, or delete data from the database.
