A low-interaction honeypot is a type of honeypot that simulates a real OS as well as the applications and services of a target network, but only responds to pre-configured commands. It is designed to capture basic information about the attacker, such as their IP address, tools, and techniques. A low-interaction honeypot is easier to deploy and maintain than a high-interaction honeypot, which fully emulates a real system and allows the attacker to interact with it. A pure honeypot is a real system that is intentionally vulnerable and exposed to attackers. A medium- interaction honeypot is a type of honeypot that offers more functionality and interactivity than a low-interaction honeypot, but less than a high-interaction honeypot.

Managing and maintaining is the phase of firewall implementation and deployment in which Elliott monitored the firewall logs in the above scenario. A firewall is a system or device that controls and filters the incoming and outgoing traffic between different networks or systems based on predefined rules or policies. A firewall can be used to protect a network or system from unauthorized access, use, disclosure, modification, or destruction.Firewall implementation and deployment is a process that involves planning, installing, configuring, testing, managing, and maintaining firewalls in a network or system.Managing and maintaining is the phase of firewall implementation and deployment that involves monitoring and reviewing the performance and effectiveness of firewalls over time.Managing and maintaining can include tasks such as updating firewall rules or policies, analyzing firewall logs , detecting evolving threats or attacks , ensuring firewall security , addressing network issues , etc. In the scenario, Elliott was tasked with implementing and deploying firewalls in the corporate network of an organization. After planning and deploying firewalls in the network, Elliott monitored the firewall logs to detect evolving threats and attacks; this helped in ensuring firewall security and addressing network issues beforehand.
This means that he performed managing and maintaining phase for this purpose. Deploying is the phase of firewall implementation and deployment that involves installing and activating firewalls in the network or system according to the plan. Testing is the phase of firewall implementation and deployment that involves verifying and validating the functionality and security of firewalls before putting them into operation. Configuring is the phase of firewall implementation and deployment that involves setting up and customizing firewalls according to the requirements and specifications.

Recovery is the business continuity and disaster recovery activity that Kasen performed in the above scenario. Business continuity and disaster recovery (BCDR) is a process that involves planning, preparing, and implementing various activities to ensure the continuity of critical business functions and the recovery of essential resources in the event of a disaster or disruption. BCDR activities can be categorized into four phases: prevention, response, resumption, and recovery . Prevention is the BCDR phase that involves identifying and mitigating potential risks and threats that can cause a disaster or disruption. Response is the BCDR phase that involves activating the BCDR plan and executing the immediate actions to protect people, assets, and operations during a disaster or disruption. Resumption is the BCDR phase that involves restoring the minimum level of services and functions required to resume normal business operations after a disaster or disruption. Recovery is the BCDR phase that involves restoring both the disaster site and the damaged materials to the pre-disaster levels during an incident.

TCP Timestamps is the vulnerability with a severity score of 8.0. This can be verified by performing a vulnerability assessment of the web server located at IP address 20.20.10.26 using the OpenVAS vulnerability scanner, available with the Parrot Security machine, with credentials admin/password. To perform the vulnerability assessment, one can follow these steps:
Launch the Parrot Security machine and open a terminal. Enter the command sudo openvas-start to start the OpenVAS service and wait for a few minutes until it is ready.
Open a web browser and navigate to https://127.0.0.1:9392 to access the OpenVAS web interface. Enter the credentials admin/password to log in to OpenVAS. Click on Scans -> Tasks from the left menu and then click on the blue icon with a star to create a new task.
Enter a name and a comment for the task, such as "Web Server Scan". Select "Full and fast" as the scan config from the drop-down menu. Click on the icon with a star next to Target to create a new target. Enter a name and a comment for the target, such as "Web Server". Enter 20.20.10.26 as the host in the text box and click on Save. Select "Web Server" as the target from the drop- down menu and click on Save. Click on the green icon with a play button next to the task name to start the scan and wait for it to finish.
Click on the task name to view the scan report and click on Results from the left menu to see the list of vulnerabilities found.
Sort the list by Severity in descending order and look for the vulnerability with a severity score of
8.0. The screenshot below shows an example of performing these steps: The vulnerability with a severity score of 8.0 is TCP Timestamps, which is an option in TCP packets that can be used to measure round-trip time and improve performance, but it can also reveal information about the system's uptime, clock skew, or TCP sequence numbers, which can be used by attackers to launch various attacks, such as idle scanning, OS fingerprinting, or TCP hijacking. The vulnerability report provides more details about this vulnerability, such as its description, impact, solution, references, and CVSS score.
