Stella's mobile device running an obsolete operating system (OS) version poses asystem-based risk. Outdated OS versions may lack critical security patches, leaving the device vulnerable to exploits and attacks. Regular OS updates are essential to address security vulnerabilities and maintain the device's security posture.

Seizing the computer and email accounts (Step 5): This is the initial step to secure potential evidence. It involves physically or remotely seizing the suspect's computer and email accounts to prevent tampering.

Acquiring the email data (Step 1): After seizing the devices, investigators acquire the email data. This includes collecting email files, attachments, and metadata.

Retrieving email headers (Step 6): Email headers contain valuable information such as sender IP addresses, timestamps, and routing details. Retrieving headers helps trace the email's origin.

Analyzing email headers (Step 2): Investigators analyze the headers to identify any anomalies, spoofing, or suspicious patterns.

Examining email messages (Step 3): Investigators review the actual email content, attachments, and any embedded links. This step helps understand the context and intent.

Recovering deleted email messages (Step 4): Deleted emails may contain critical evidence. Investigators use specialized tools to recover deleted messages.

Atransposition cipherrearranges characters or bits of plaintext to produce ciphertext. In Kevin's scenario, he used an algorithm that rearranges the same characters to create the ciphertext. This aligns with the characteristics of a transposition cipher, where the order of characters is altered without changing their identity.

Daniel's action of making a copy of computer programs while maintaining or repairing the system aligns with the provisions of theDigital Millennium Copyright Act (DMCA).The DMCA allows for certain exemptions related to circumventing technological protection measures (TPMs) for purposes of maintenance or repair1. Specifically, section 117 of the U.S.Copyright Code permits the owner or lessee of a machine to make a copy of a computer program solely for maintenance or repair if certain conditions are met1. In this case, Daniel's authorized copying falls within the scope of this provision.Reference: U.S.Copyright Code, Title 17, Section 1171.

Comprehensive Explanation: TheAutopsytool is a digital forensics platform that assists investigators in analyzing and recovering evidence from various sources. One of its crucial functions isdata carving. Here's how it works:

Data Carving:

Data carving, also known asfile carving, is a technique used to retrieve files from unallocated space on storage devices.

When files are deleted, they may not be immediately overwritten. Instead, their remnants remain in unallocated areas of the storage medium.

Autopsy'sPhotoRec Carver moduleperforms data carving by scanning unallocated space, identifying file signatures, and recovering deleted files.

These files are often found in seemingly ''empty'' portions of the device storage.

By analyzing unallocated space, Autopsy can uncover potential evidence that was previously deleted.

Messy has deployed ananomaly-basedIntrusion Detection System (IDS). This type of IDS observes and compares observed events with normal behavior, detecting deviations from the established patterns.It identifies anomalies that may indicate potential security threats.Reference: EC-Council Certified Security Specialist (E|CSS) course materials12.

In this scenario, Wesley's use of an unauthorized third-party mobile app to sync with his Apple smartwatch highlights the risk ofimproper platform usage. Here's why:

Unauthorized Third-Party App: Wesley downloaded the app from an unauthorized source, which means it hasn't undergone proper security checks or vetting. Such apps may contain vulnerabilities or malicious code.

Unusual Report and Unnecessary Permissions: The app generated an unusual fitness report and requested unnecessary permissions. This behavior indicates that the app is not following proper guidelines for platform usage.

Platform Security Guidelines: Mobile platforms (like iOS or Android) have specific guidelines for app development and usage. When users sideload apps from untrusted sources, they bypass these guidelines, risking security and privacy.

Risk Implications:

Data Privacy: Unauthorized apps may mishandle sensitive data (like fitness reports), leading to privacy breaches.

Malware or Spyware: The app could contain malicious code, potentially compromising the device or user data.

Permissions Abuse: Requesting unnecessary permissions can lead to data leakage or unauthorized access.

EC-Council's focus on information security emphasizes the importance of proper platform usage and adherence to guidelines1.

In the given scenario, the banking application employstwo-factor authentication (2FA). Here's why:

Registered Credentials: Kevin logs in with hisregistered credentials(username and password).

OTP (One-Time Password): The application sends anOTP to Kevin's mobilefor confirmation. This OTP serves as thesecond factorof authentication.

Two-factor authentication enhances security by requiring users to provide two different authentication factors (usually something they know, like a password, and something they have, like an OTP) before granting access. It helps protect against unauthorized access even if one factor is compromised.

Thenetstat -anocommand is used to display all active connections and their respective states on a system. When the Tor browser is closed, the connections it established would no longer be active.The state that indicates a connection is no longer active and is in the process of closing isTIMEWAIT1.

In the context of TCP/IP networking,TIMEWAITis a state that occurs after a connection has been terminated by the application, and the system is waiting to ensure that all packets have been received to prevent any delayed packets from appearing in subsequent connections2. This state helps to ensure that a new connection does not receive packets from an old connection, which is particularly important in ensuring the security and integrity of data transmission.

The other states listed have different meanings:

A . ESTABLISHED: This state means that the connection is currently active and data can be transferred.

B . CLOSE WAIT: This state indicates that the remote end has shut down, and the local end is waiting for the application to close the connection.

D . LISTENING: This state signifies that the server is waiting for incoming connections on a specific port.

Therefore, the correct answer is C, TIMEWAIT, as it represents the state where the connection has been closed by the application, which in this case would be the Tor browser.
