Enabling the “Allow subdissector to reassemble TCP streams” feature in Wireshark allows the tool to reassemble TCP segments into a contiguous sequence, which can be used by higher-level protocols to reconstruct a full message, such as an HTTP request or response. This is particularly useful for extracting files or data transmitted over TCP that are spread across multiple packets1.

References := The explanation is based on the Wireshark documentation, which details how the reassembly feature works and its use in analyzing TCP streams

 DNS amplification is a type of Distributed Denial of Service (DDoS) attack where an attacker uses publicly accessible open DNS servers to flood a target with DNS response traffic. The goal is to overwhelm the target with traffic, causing a denial of service.

Encryption is challenging to security monitoring because it can be used by threat actors as a method of evasion and obfuscation. Encryption can prevent security devices from inspecting the content or payload of the network traffic, making it difficult to detect malicious activity or signatures. Encryption can also hide the source and destination of the traffic, making it hard to trace the origin or destination of the attack. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1-0/CSCU-LP-CBROPS-V1-028093.html (Module 4, Lesson 4.1.1)
