IP spoofing is a hostile attack in which the threat actor conceals the true source of IP packets to make it harder to determine where they originated. To mimic a different computer system, hide the sender's identity, or both, the attacker produces packets with a new source IP address.
IP spoofing is also known as host file hijacking or IP address forging. It is a method of gaining unauthorised access to computers (servers) in which the attacker sends messages to a computer network using an IP address that indicates the message is coming from a trusted IP host.
The packet headers of data packets are analysed for inconsistencies to detect IP spoofing. The IP address can be verified using the MAC (Media Access Control) address or a security system like Cisco's IOS NetFlow, which assigns a unique ID and timestamp to each computer that connects to the network.
The consequences for IP spoofing can range from legal action to monetary loss. It is important to take measures to keep your intellectual property safe such as using a password protected document that has been encrypted with a strong password and only sharing it with people who need access to it.
