Abstract
Provided are methods and systems for network access control. A method for network access control may commence with determining whether a client device is a trusted source or an untrusted source. The determination may be performed using a SYN packet received from the client device. The SYN packet may include identifying information for the client device. When it is determined that the client device is neither the trusted source nor the untrusted source, the method may continue with transmitting a SYN/ACK packet to the client device. The SYN/ACK packet may include a SYN cookie and identifying information for a network device. The method may further include receiving an ACK packet from the client device that may include the identifying information for the client device, identifying information for the network device, and the SYN cookie. The method may continue with establishing a connection with a network for the client device.
