For end-users, secure shell (SSH) and secure socket layers (SSL) help mitigate attacks, but we’ll discuss why this can’t eradicate the problem later. The result is that web engineers often try to find new ways to protect information traveling across the web.įor example, IPv6 is a newer protocol that builds encryption and authentication. As such, this can breach even the most stringent and secure of networks.

IP spoofing uses the source IP header and changes some of the details to make it appear as though it’s genuine. In theory, this is supposed to ensure that data arrives at a destination free from tampering. Moreover, every packet also has its identifiable information (a “header”) that will include the IP address from both the source and the destination. Then once they reach the end of the chain, they’re reassembled and presented as a whole. Each packet travels on an individual basis.

To better understand IP spoofing, let’s give you some context on how the internet sends and uses data.Įvery computer uses an IP address, and any data you send is broken into many chunks (“packets”). 😥 Learn more in this guide 👇 Click to Tweet IP spoofing is a common way for malicious users to gain quick credibility, and almost anyone using the internet could be vulnerable. We’ll talk more about both of these attacks in greater detail later. Machine-in-the-middle (MITM) attacks also utilize IP spoofing because the MITM approach relies on faking trust between two endpoints. Here, spoofing the IP makes the attack difficult to detect until it’s too late, and it’s similarly hard to trace after the fact. This uses a collection of bots using spoofed IP addresses to send data to a particular site and server, taking it offline. To get more technical, IP spoofing takes the data and changes some identifiable information at a network level.

It involves linking a computer’s media access control (MAC) address to a legitimate IP using spoofed ARP messages. Address resolution protocol (ARP) spoofing: An ARP spoofing attempt is one of the more complex attacks.Domain name server (DNS) spoofing: This will modify the source IP of the DNS to redirect a domain name to a different IP.IP address spoofing: This is a straightforward obfuscation of the attacker’s IP address to conduct denial-of-service (DoS) attacks, and more.IP spoofing is a wide-ranging term for many different attacks: In a general sense, IP spoofing takes a portion of the data you send over the internet and makes it seem as though it’s from a legitimate source.
