Final answer:
Spear Phishing and Denial of Service (DoS) are the two types of attacks that target endpoints, with the former aiming to steal information through deceptive emails, and the latter intending to overload systems with traffic.
Step-by-step explanation:
The two attack types that target endpoints are Spear Phishing and Denial of Service (DoS). Spear Phishing is a targeted attack where attackers send emails to specific individuals or organizations with the intent to steal sensitive information.
These emails typically appear to be from a trusted source but are malicious. Denial of Service attacks, on the other hand, aim to make a computer resource unavailable to its intended users by overwhelming it with traffic, which can cause the system to crash or become inoperable.
