Sequence Number Definition: Sequence Number is a unique identifier assigned to each packet transmitted over a network connection, allowing the recipient to order and reassemble the packets in the correct sequence.
A Sequence Number in cybersecurity refers to a unique identifier assigned to individual data packets sent over a network. It helps in ensuring the successful and orderly transmission of the packets from a sender to a receiver. Sequence numbers are crucial for data integrity and security as they aid in detecting any potential tampering, loss, or duplication of data during transmission. These numbers are typically used in protocols like TCP (Transmission Control Protocol) to maintain the correct order of data packets and confirm successful data delivery.
