Computer network security is one of the main concerns for most organizations these days. It has become such a prevalent issue, that there are specialized departments and fields of study dedicated to it. Whether you use a highly secure workplace internet connection or the basic network you got from your Altice One Optimum, you need to protect your data and systems from any breaches. 

Spoofing is one of the ways these breaches misuse your network. It basically refers to the situation where someone attempts to use a device, computer, or network to trick other systems by pretending to be a legitimate entity. Then, they take control of these computers for malicious purposes or launch Denial of Service (DoS) attacks. There are many different types of spoofing behaviors, but IP spoofing is the most common.  

What is IP Spoofing?

IP spoofing is defined as a situation where Internet Protocol (IP) packets are created with falsified source addresses to mask the sender’s identity or impersonate other computer senders. Usually, IP spoofers simply modify the content in the IP source header, using randomized numbers. 

Resultantly, when other computers receive these IP packets, they think they are from trustworthy sources, and let them pass. Then, these packets carry out their true intended behavior, and either take control of the system, or launch DoS attacks. As all of this takes place at the network level, there are no obvious external signs of tampering for early detection. 

How Can You Avoid It?

You should avoid IP spoofing at all costs. It can create major issues for your computer systems and result in widespread network problems. This is especially true for workplace networks, as these contain sensitive data and information. 

Furthermore, companies stand to lose considerable amounts of revenue and even clients if they fall prey to IP spoofing. Therefore, you need to avoid this malicious attack to the best of your abilities. There are many ways to avoid IP spoofing, such as the ones given below. 

Monitor Networks for Suspicious Activity

This is the first and foremost thing you should do against any sort of network issues. Use a variety of tools and best practices to ensure that you know what is going on in your networks. If there are any discrepancies or odd behavior, they should be flagged and inspected immediately. 

You’ll probably need a dedicated team of cybersecurity experts on board for this purpose. Make sure they have access to the whole network, including employee systems, so that they can detect and halt any suspicious activity as soon as possible. 

Deploy Packet Filtering Systems

These tools can help you detect any discrepancies in incoming and outgoing IP packets. An IP packet filtering system will let you know if there are any IPs in the network which do not match the ones usually shared on the systems. It will flag any such IPs so that the relevant teams can take the appropriate action. 

You can find such systems from various software developers, or develop your own in-house system. These systems whitelist your company’s IP addresses and prevent any outliers from immediately entering your network. Your cybersecurity teams can thoroughly vet and isolate these IPs and see whether they’re safe for your systems.

Furthermore, you should authenticate incoming and outgoing IP addresses and see whether they fit company protocols. Otherwise, cybersecurity should immediately take action against such IPs.   

Use Tough Verification Mechanisms

Often, office networks have mechanisms in place for remote access to other systems. However, if a false-flag IP has already infiltrated one computer, it can affect the rest of the system as well. Therefore, it is best to have a few safety protocols in place to prevent these issues. 

Multi-factor verification can really help prevent such infiltration, as the users of the other systems will have to confirm whether the incoming IPs can access their devices. This can help prevent such attacks by stopping them and not letting them get any further.  

Use Network Attack Blocker

You need to install failsafe to prevent malicious network attacks. From firewalls and anti-virus software to monitoring systems, you need to use every tool in your kit to protect your networks. These will prevent spoofed IPs from tricking your devices and affecting your networks. 

Therefore, you should look into a network attack blocker. A simple firewall won’t just do the trick. You’ll need sophisticated software especially designed for this purpose. You can easily find these online and get the right choices for your budget. 

To sum up, there are numerous reasons why you need to avoid IP spoofing on your systems. However, there are numerous protective measures as well. These will protect your networks from malicious activities.
