When a company workstation is compromised, the stakeholders that must be involved are the ones who are responsible for the security incident response process. According to the table, these are Employee 4 (Security Operation Center Analyst), Employee 6 (Head of Network and Security Infrastructure Services), and Employee 7 (Technical Director). The other employees have different roles that are not directly related to the incident response process, such as accounting, financial management, or system administration. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 1: Security Concepts, Lesson 1.4: Security Monitoring, Topic 1.4.1: Security Operations Center

The scenario described is indicative of a port scanning attack. Port scanning is a method used by attackers to discover open ports on network devices. A single SYN packet sent to each port is a technique known as SYN scanning or half-open scanning, where the attacker sends a SYN message (as if they are going to initiate a TCP connection) to every port on the server, looking for positive responses which indicate an open port. This type of scanning is less intrusive and harder to detect because it never completes the TCP three-way handshake1.

 In the context of public key infrastructure (PKI), a trusted certificate authority (CA) is responsible for issuing digital certificates that verify a digital entity’s identity on the internet. The CA acts as a trusted third party between the user (in this case, tom0411976943) and the recipient (dan1968754032), ensuring that the public keys are indeed who they claim to be. The CA verifies the identity of the users and then issues a certificate containing the public key and a variety of other identification information. The trusted CA can then vouch for the authenticity of each user to the other.
