A. All TCPoptions are supported, such as largewindows. B. The server can have more than8 unique MSS values. C. SYN cookies are not implemented as a method of defending against SYN floods. D. SYN cookies are...
The TCP SYN Flood attack is not a new phenomenon. Its origins can be traced back to the dawn of the internet when network security was in its infancy. As the internet grew in popularity and commercial significance, malicious actors became more motivated to exploit potential vulnerabilities. Early...

SYN flood process Hackers usually send a large number of SYN packets with fake source IP addresses or ports to the server to request the establishment of TCP connections. As the source IP address or port is forged, the SYN-ACK packet sent by the server will never be received or replied to...
SYN scan: Also called a half-open scan, this sends a SYN flag to the target and waits for a SYN-ACK response. In the event of a response, the scanner does not respond back, which means the TCP connection was not completed. Therefore, the interaction is not logged, but the sender lea...
SYN Scan (Half-Open Scan): Involves sending a SYN packet and waiting for a SYN-ACK response without completing the TCP handshake, making it harder to detect. FIN Scan: Technique sends a FIN packet to closed ports, which triggers a reset (RST) response. It is commonly used to bypass fir...
Open: your destination replies with a message indicating that it is listening on that port and the service used for the scan (often TCP or UDP). Closed: the destination received the request packet but returned a response indicating that no service was listening at the port. Filtered: the por...
Stealth Scan (SYN Scan) The SYN scan, also known as a half-open scan or stealth scan, is one of the most commonly used port scanning techniques. It works by sending a TCP SYN (synchronise) packet to initiate a connection. If the target port is open, the system responds with a SYN-...
UDP Port Scan Attackers send UDP packets to ports on a server to determine which ports are open. If a server responds with an ICMP ‘Destination Unreachable’ message, the port is not open. If there is no such response, the attacker infers that the port is open, and then use this infor...
