Event ID 4740 is a security audit event in Windows that indicates a user account has been locked out. This event is generated every time the system locks out a user account due to repeated logon failures, which are typically caused by incorrect password entries. The event is logged on domain controllers, member servers, and workstations where the lockout occurred. It includes details such as the account name, domain, and the computer from which the lockout originated.

References: The information is verified as per Microsoft’s official documentation and learning resources related to security auditing and user account management. Specifically, the Microsoft Learn page on security auditing provides comprehensive details on Event ID 47401. Additionally, resources like Ultimate Windows Security offer in-depth explanations of this event and its implications for security monitoring2.

Insecure deserialization often leads to critical vulnerabilities allowing attackers to perform various attacks, such as remote code execution. To mitigate these vulnerabilities, Wesley should avoid considering the serialization of security-sensitive classes because it can expose sensitive data to untrusted sources or lead to arbitrary code execution.

Here are the steps Wesley should follow:

• Avoid Serialization of Sensitive Data: Do not serialize sensitive information. If it’s essential to serialize, then ensure it’s encrypted and the process is secure.
• Implement Integrity Checks: Use digital signatures or checksums to verify that the serialized data has not been tampered with before deserializing it.
• Enforce Strict Type Constraints: When deserializing, ensure that the data adheres to strict type constraints to prevent the instantiation of unexpected types.
• Logging and Monitoring: Keep detailed logs of serialization and deserialization processes to monitor for any suspicious activities.
• Security Controls Review: Regularly review and update security controls related to serialization and deserialization to ensure they are effective against emerging threats.

• The CSA certification emphasizes the importance of understanding the security risks associated with serialization and deserialization and implementing best practices to mitigate these risks12.
• Additional resources and study guides from EC-Council’s official materials on the Certified SOC Analyst (CSA) program would provide more in-depth strategies and practices for handling insecure deserialization attacks12.

To monitor and visualize Tor traffic hitting the network, John would need data sources that can provide detailed information about the source IP addresses of incoming traffic, as well as the capability to resolve these IP addresses to more identifiable information such as hostnames or geographical locations. DHCP logs, or other log sources capable of maintaining detailed IP address records and facilitating IP-to-Name resolution, would be suitable for this purpose. This data would allow John to create a dashboard in the SIEM system that maps the source IP addresses of Tor traffic to their corresponding locations or identities, providing insights into where the Tor traffic is originating. While web server logs (options B, C, and D) can provide IP addresses, they might not offer the same level of detail or resolution capabilities as DHCP logs or similar network-level logs for this specific use case.
