 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.

The Nmap scan results show that several ports, including ftp (21/tcp), ssh (22/tcp), telnet (23/tcp), smtp (25/tcp), and http (80/tcp), are listed as “filtered”. This typically indicates that a firewall is filtering the traffic to these ports, making it impossible to determine whether they are open without further investigation. However, the question specifically asks about SMB ports, which are not shown in the provided Nmap scan results. Therefore, based on the information given, we cannot confirm that the attacker identified open SMB ports on the server. The correct answer would require additional evidence not present in the scan results. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course materials and official Cisco documentation provide insights into interpreting Nmap scan results and identifying port states. These resources can be found at the Cisco Learning Network Store and Cisco’s official training and certifications webpage

Asymmetric cryptography, also known as public key cryptography, involves two keys: a public key for encryption and a private key for decryption. This method ensures that even if the public key is known, only the holder of the private key can decrypt the message, thus providing a secure way to transfer data. References: Asymmetric encryption is beneficial for secure data transfer because it allows message authentication, non-repudiation, and detects tampering, although it is slower than symmetric encryption

An untampered disk image is one that has not been altered since its creation. This is verified by comparing the stored hash of the image at the time of creation with a newly computed hash; if they match, the image is considered untampered. Tampered images, on the other hand, may be used during the root cause analysis process to understand how and what was altered12. References: The differences between tampered and untampered disk images are discussed in cybersecurity literature, including Cisco’s certification guides, which explain the importance of hash matching for verifying the integrity of disk images
