We can take a couple of preventive measures to prevent TCP sequence prediction attacks.
- Instead of a predicted sequence number, a random sequence number can be used to track the data packets. In that way, it will be difficult for the attacker to predict the sequence number and perpetrate the attack.
- Instead of a sequence number, other information like time stamps, timing differences, or information from lower protocol layers can be used in the data packets. This can prove much more difficult for the attackers to guess and perform such attacks.
- We can configure the router or firewall not to allow packets to come in from external sources with having an internal IP address. Though this may not completely fix the attacks, it can prevent the attacks to a great extent.
So, be informed about the most common threats and stay safe and secure.
