20.20.10.19 is the source IP address of the SYN flooding attack in the above scenario. SYN flooding is a type of denial-of-service (DoS) attack that exploits the TCP (Transmission Control Protocol) three-way handshake process to disrupt the network and gain advantage over the network to bypass the firewall. SYN flooding sends a large number of SYN packets with spoofed source IP addresses to a target server, causing it to allocate resources and wait for the corresponding ACK packets that never arrive. This exhausts the server's resources and prevents it from accepting legitimate requests . To determine the source IP address of the SYN flooding attack, one has to follow these steps:

Navigate to the Documents folder of Attacker-1 machine.

Double-click on Synflood.pcapng file to open it with Wireshark.

Click on Statistics menu and select Conversations option.

Click on TCP tab and sort the list by Bytes column in descending order.

Observe the IP address that has sent the most bytes to 20.20.10.26 (target server).

The IP address that has sent the most bytes to 20.20.10.26 is 20.20.10.19 , which is the source IP address of the SYN flooding attack.

A hub-and-spoke VPN topology is a type of VPN topology where all the remote offices communicate with the corporate office, but communication between the remote offices is denied. The corporate office acts as the hub, and the remote offices act as the spokes. This topology reduces the number of VPN tunnels required and simplifies the management of VPN policies. A point-to-point VPN topology is a type of VPN topology where two endpoints establish a direct VPN connection. A star topology is a type of VPN topology where one endpoint acts as the central node and connects to multiple other endpoints. A full-mesh VPN topology is a type of VPN topology where every endpoint connects to every other endpoint.

3 is the number of files present in the folder in the above scenario. A RAT (Remote Access Trojan) is a type of malware that allows an attacker to remotely access and control a compromised system or network. A RAT can be used to steal sensitive data, spy on user activity, execute commands, install other malware, etc. To initiate a remote connection using thief client, one has to follow these steps:

Navigate to the thief folder located at Z:\CCT-Tools\CCT Module 01 Information Security Threats and Vulnerabilities\Remote Access Trojans (RAT)\Thief of Attacker Machine-1.

Double-click on thief.exe file to launch thief client.

Enter 20.20.10.26 as IP address of server.

Enter 1234 as port number.

Click on Connect button.

After establishing connection with server, click on Browse button.

Navigate to Desktop folder on server.

Count number of files present in folder.

The number of files present in folder is 3, which are:

Sensitive corporate docs.docx

Sensitive corporate docs.pdf

Sensitive corporate docs.txt

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.

WPA3 encryption is the type of wireless encryption used by the security solution employed by Matias in the above scenario. WPA3 encryption is the latest and most secure version of Wi-Fi Protected Access, a protocol that provides authentication and encryption for wireless networks. WPA3 encryption uses 256-bit Galois/Counter Mode Protocol (GCMP-256) to maintain the authenticity and confidentiality of data. WPA3 encryption also provides enhanced protection against offline dictionary attacks, forward secrecy, and secure public Wi-Fi access . WPA2 encryption is the previous version of Wi-Fi Protected Access, which uses Advanced Encryption Standard (AES) or Temporal Key Integrity Protocol (TKIP) for data encryption. WEP encryption is an outdated and insecure version of Wi-Fi security, which uses RC4 stream cipher for data encryption. WPA encryption is an intermediate version of Wi-Fi security, which uses TKIP for data encryption.
