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 PointsWhen 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 phishingSupply chain compromisesSoftware vulnerabilitiesExposed credentialsInsider threatsProvide examples of security events that should be collected from each of these data sources.What would trigger an investigation into a potential security violation?ResourcesTable $16.$ Comparison of Common Security$-$Relevant Data Sources; Ten Strategies of a World$-$Class Security Operations Center Links to an external site. by Carson ZimmermanMitre ATT&CK Navigator Links to an external site.Select Create New Layer and EnterpriseSelect the relevant techniques to access a detailed description to include data sources.Click on the $?$ icon to the right of the ATT&CK$$ Navigator title to view its documentation
