Integrating Linux machines with a Windows environment for centralized log management poses significant challenges, primarily due to the incompatibility of log formats:

Log Format Differences:

Windows: Uses Event Viewer to store logs in a proprietary format.

Linux: Uses Syslog to store logs in plain text files with a different structure.

Centralized Management: To achieve effective centralized log management, logs from both systems need to be normalized into a common format.

Solutions:

Log Aggregators: Tools like Logstash or Fluentd can collect, parse, and transform logs from different systems into a unified format.

SIEM Systems: Security Information and Event Management (SIEM) systems like Splunk or ELK Stack can handle log ingestion from multiple sources, normalizing data for analysis.

Strong Security:

EAP-TLS provides strong security by using certificate-based authentication. This ensures that both the client and server are authenticated before a connection is established.

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.

Investigation objectives is the section of the forensic investigation report where Arabella recorded the “nature of the claim and information provided to the officers” in the above scenario. A forensic investigation report is a document that summarizes the findings and conclusions of a forensic investigation. A forensic investigation report typically follows a standard template that contains different sections covering all the details of the crime and the investigation process. Investigation objectives is the section of the forensic investigation report that describes the purpose and scope of the investigation, the nature of the claim and information provided to the officers, and the questions or issues to be addressed by the investigation. Investigation process is the section of the forensic investigation report that describes the steps and methods followed by the investigators, such as evidence collection, preservation, analysis, etc. Evidence information is the section of the forensic investigation report that lists and describes the evidence obtained from various sources, such as devices, media, witnesses, etc. Evaluation and analysis process is the section of the forensic investigation report that explains how the evidence was evaluated and analyzed using various tools and techniques, such as software, hardware, etc.

Dynamic Baseline Establishment:

Machine learning algorithms can analyze vast amounts of network traffic data over an extended period, such as a month, to understand normal and abnormal patterns dynamically.

Performing a vulnerability assessment on an Android device using OpenVAS involves several steps. Here’s how to approach this practical task:

OpenVAS Setup: Ensure OpenVAS is installed and properly configured on Parrot Security OS.

Scan Configuration:

Launch OpenVAS and log in using the provided credentials (admin/password).

Navigate to the "Scans" section and create a new task.

Target Specification:

Set the target IP address to172.30.20.110.

Perform the Scan:

Initiate the scan and wait for it to complete. The duration will depend on the network and device complexity.

Analyze Results:

Once the scan completes, review the report generated by OpenVAS.

Identify the severity score, which is typically displayed as part of the scan results summary.

Success audit is the type of event that Brielle identified in the above scenario. Success audit is a type of event that records successful attempts to access a network device or resource. Success audit can be used to monitor authorized activities on a network, but it can also indicate unauthorized activities by malicious actors who have compromised credentials or bypassed security controls4.

Hardware-assisted virtualization is a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment. The virtual machine manager (VMM) willdirectly interact with the computer hardware, translate commands to binary instructions, and forward them to the host OS. Hardware-assisted virtualization relies on special hardware features in the CPU and chipset to create and manage virtual machines efficiently and securely34. Full virtualization is a virtualization approach in which the guest OS will not be aware that it is running in a virtualized environment, but the VMM will run in software and emulate all the hardware resources for each virtual machine5. Hybrid virtualization is a virtualization approach that combines hardware-assisted and full virtualization techniques to optimize performance and compatibility6. OS-assisted virtualization is a virtualization approach in which the guest OS will be modified to run in a virtualized environment and cooperate with the VMM to access the hardware resources

The correct answer is A, as it identifies the type of Internet access policy implemented by Ashton in the above scenario. An Internet access policy is a set of rules and guidelines that defines how an organization’s employees or members can use the Internet and what types of websites or services they can access. There are different types of Internet access policies, such as:

Paranoid policy: This type of policy forbids everything and imposes strict restrictions on all company computers, whether it is system or network usage. This policy is suitable for organizations that deal with highly sensitive or classified information and have a high level of security and compliance requirements.

Prudent policy: This type of policy allows some things and blocks others and imposes moderate restrictions on company computers, depending on the role and responsibility of the user. This policy is suitable for organizations that deal with confidential or proprietary information and have a medium level of security and compliance requirements.

Permissive policy: This type of policy allows most things and blocks few and imposes minimal restrictions on company computers, as long as the user does not violate any laws or regulations. This policy is suitable for organizations that deal with public or general information and have a low level of security and compliance requirements.

Promiscuous policy: This type of policy allows everything and blocks nothing and imposes no restrictions on company computers, regardless of the user’s role or responsibility. This policy is suitable for organizations that have no security or compliance requirements and trust their employees or members to use the Internet responsibly.

In the above scenario, Ashton implemented a paranoid policy that forbids everything and imposes strict restrictions on all company computers, whether it is system or network usage. Option B is incorrect, as it does not identify the type of Internet access policy implemented by Ashton in the above scenario. A prudent policy allows some things and blocks others and imposes moderate restrictions on company computers, depending on the role and responsibility of the user. In the above scenario, Ashton did not implement a prudent policy, but a paranoid policy. Option C is incorrect, as it does not identify the type of Internet access policy implemented by Ashton in the above scenario. A permissive policy allows most things and blocks few and imposes minimal restrictions on company computers, as long as the user does not violate any laws or regulations. In the above scenario, Ashton did not implement a permissive policy, but a paranoid policy. Option D is incorrect, as it does not identify the type of Internet access policy implemented by Ashton in the above scenario. A promiscuous policy allows everything and blocks nothing and imposes no restrictions on company computers, regardless of the user’s role or responsibility. In the above scenario, Ashton did not implement a promiscuous policy, but a paranoid policy.
