NEW QUESTION # 41
Kevin, a professional hacker, wants to penetrate CyberTech Inc.'s network. He employed a technique, using which he encoded packets with Unicode characters. The company's IDS cannot recognize the packet, but the target web server can decode them.
What is the technique used by Kevin to evade the IDS system?
- A. Obfuscating
- B. Urgency flag
- C. Desynchronization
- D. Session splicing
Answer: A
Explanation:
Obfuscating is the technique used by Kevin to evade the IDS system in the above scenario. Obfuscating is a technique that involves encoding or modifying packets or data with various methods or characters to make them unreadable or unrecognizable by an IDS (Intrusion Detection System). Obfuscating can be used to bypass or evade an IDS system that relies on signatures or patterns to detect malicious activities. Obfuscating can include encoding packets with Unicode characters, which are characters that can represent various languages and symbols. The IDS system cannot recognize the packet, but the target web server can decode them and execute them normally. Desynchronization is a technique that involves creating discrepancies or inconsistencies between the state of a connection as seen by an IDS system and the state of a connection as seen by the end hosts. Desynchronization can be used to bypass or evade an IDS system that relies on stateful inspection to track and analyze connections. Desynchronization can include sending packets with invalid sequence numbers, which are numbers that indicate the order of packets in a connection. Session splicing is a technique that involves splitting or dividing packets or data into smaller fragments or segmentsto make them harder to detect by an IDS system. Session splicing can be used to bypass or evade an IDS system that relies on packet size or content to detect malicious activities. Session splicing can include sending packets with small MTU (Maximum Transmission Unit) values, which are values that indicate the maximum size of packets that can be transmitted over a network. An urgency flag is a flag in the TCP (Transmission Control Protocol) header that indicates that the data in the packet is urgent and should be processed immediately by the receiver.
An urgency flag is not a technique to evade an IDS system, but it can be used to trigger an IDS system to generate an alert or a response.
