CAPEC-287: TCP SYN Scan
Description
An adversary uses a SYN scan to determine the status of ports on the remote target. SYN scanning is the most common type of port scanning that is used because of its many advantages and few drawbacks. As a result, novice attackers tend to overly rely on the SYN scan while performing system reconnaissance. As a scanning method, the primary advantages of SYN scanning are its universality and speed.
- Likelihood of attack
- Not rated by MITRE
- Typical severity
- Low
- Abstraction
- DetailedA low-level, detailed pattern, often for a particular technology.
Mechanism of attack: Collect and Analyze Information
Prerequisites
- This scan type is not possible with some operating systems (Windows XP SP 2). On Linux and Unix systems it requires root privileges to use raw sockets.
Consequences
- Confidentiality
Other
A successful attack of this kind can identify open ports and available services on a system.
