Explanation
Session data provides information about the five tuples; source IP address/port number, destination IP address/port number and the protocol What is Connectivity Data? According to IBM - Connectivity data defines how entities are connected in the network. It includes connections between different devices, and VLAN-related connections within the same device https://www.ibm.com/docs/en/networkmanager/4.2.0?topic=relationships-connectivity-data

In the context of incident response, the detection step involves identifying potential security incidents. The Security Operation Center (SOC) Analyst, which in this case is Employee 4, is typically responsible for monitoring and analyzing security alerts to detect suspicious activities such as brute-force attempts. Therefore, Employee 4 would be the stakeholder responsible for the incident response detection step. References: The role of a SOC Analyst in incident response is outlined in cybersecurity frameworks and best practices, which describe the responsibilities of various stakeholders in detecting and responding to security incidents.

Social engineering is a tactic used by attackers to manipulate individuals into divulging confidential information, such as passwords. In this scenario, the attacker is impersonating a colleague by using a similar email address with a missing letter, attempting to trick the employee into revealing sensitive information.
