Throughout this course, you have read in$-$depth accounts of security breaches that resulted from various attack vectors such as spear phishing, supply

chain compromise, software vulnerabilities, exposed credentials, and even insider threats. The early detection of a breach can reduce its impact on an

organization, thereby minimizing productivity loss, regulatory fines, and reputational damage. Catching an attacker in the early stages of a campaign relies

on continuous monitoring of endpoint and network activity and well$-$tuned detection logic. Security teams must have access to relevant data sources, such

as an application, network device, or endpoint logs$,$ for detections to fire.

For this discussion, construct your response using the key talking points below.

Key Talking Points

When considering the techniques attackers use to gain initial access to an environment, which of the following are the most critical data sources for

early detection?

Spear phishing

Supply chain compromises

Software vulnerabilities

Exposed credentials

Insider threats

Provide examples of security events that should be collected from each of these data sources.

What would trigger an investigation into a potential security violation?
