What is Christmas tree attack?
A Christmas Tree Attack is a very well known attack that is designed to send a very specifically crafted TCP packet to a device on the network. This crafting of the packet is one that turns on a bunch of flags. And these flags all are turned on or turned off, depending on what the packet is doing.
What is SYN SYN ACK ACK?
SYN-ACK is a SYN message from local device and ACK of the earlier packet. FIN is used for terminating a connection. TCP handshake process, a client needs to initiate the conversation by requesting a communication session with the Server….
What is TCP 4 way handshake?
The “normal” TCP connection tear-down is performed with a 4-way handshake. Specifically, in order for an established TCP connection to be terminated, the following 4 TCP packets are exchanged: Host A → Host B: FIN flag set. Host B → Host A: ACK flag set. Host A → Host B: ACK flag set.
What are TCP states?
A connection progresses through a series of states during its lifetime. The states are: LISTEN, SYN-SENT, SYN- RECEIVED, ESTABLISHED, FIN-WAIT-1, FIN-WAIT-2, CLOSE-WAIT, CLOSING, LAST-ACK, TIME-WAIT, and the fictional state CLOSED….
What are valid TCP control flags?
In TCP connection, flags are used to indicate a particular state of connection or to provide some additional useful information like troubleshooting purposes or to handle a control of a particular connection. Most commonly used flags are “SYN”, “ACK” and “FIN”. Each flag corresponds to 1 bit information….
How many bits is a TCP flag?
9 bits
How long is TCP header?
Specifies the size of the TCP header in 32-bit words. The minimum size header is 5 words and the maximum is 15 words thus giving the minimum size of 20 bytes and maximum of 60 bytes, allowing for up to 40 bytes of options in the header.
What is the order of TCP flags?
What ordering of TCP flags makes up the Three-way Handshake? SYN, SYN/ACK, ACK; The computer that wants to establish a connection sends a packet with the SYN flag set. Then, the server responds with a packet with both the SYN and ACK flags set. Finally, the original computer sends a packet with just the ACK flag set.
What is TCP segmentation?
Segmentation is the process of carving up information into smaller pieces. TCP receives data from an application and segments the data into pieces. This segmentation is necessary so that the information can be placed inside the TCP data field. Once the data is segmented it is encapsulated within TCP….
