Understanding Piggybacking in Networking & Security



Welcome to our piece on piggybacking in networking and security. Today, we’re connected more than ever. Whether we’re in a café or at home, we rely on wireless networks. But, using these networks without care can lead to big security issues. Piggybacking is one such risk. It means using a network without permission.

Imagine walking into a coffee shop and connecting to their network, even though you haven’t asked. That’s piggybacking. It’s common in places that leave their Wi-Fi open and free. This kind of access can also put your data at risk, letting others see what you’re doing online without you knowing.

In this article, we’ll explain piggybacking in more detail. We’ll look at how it happens and why it’s a big deal for your safety online. We’ll also compare it to tailgating and share some piggybacking stories. Plus, we’ll cover how to stop it and talk about when piggybacking is actually a good thing.

Learning about piggybacking and how to keep your network safe is important. Security is in our hands. So, let’s get started exploring the “wild” world of networking and security!

What is Piggybacking?

Piggybacking is using a wireless network without permission. Imagine someone connecting to an open Wi-Fi at a coffee shop without asking. They do this without the owner knowing.

This is risky because secret info like your personal and financial data might get seen. This is a threat when someone piggybacks on your Wi-Fi.

It often happens in places offering Wi-Fi where people can access it from outside. For instance, many like getting free Wi-Fi at coffee shops. The owners may be clueless that people are using their Wi-Fi without them allowing it.

A simple way to stop piggybacking is by putting passwords on your Wi-Fi. Plus, it’s smart to keep an eye out for any strangers using it. These actions can keep your Wi-Fi safe from unknown visitors.

How does Piggybacking work?

In the world of unauthorized Wi-Fi access, people need to be close to the router to connect. Then, they can access the network in two ways.

  1. Connecting directly: If the network is unprotected, you can connect without a password. This is the basic method of piggybacking. Without security, the network is easy to exploit.
  2. Guessing or finding the password: With a password, piggybackers might guess it or find it with tricks. They use social engineering or find weak spots in security. Then, they can connect without the owner knowing.

Unauthorized Wi-Fi access happens in various places, like people using a business’s network without permission. For instance, someone at a coffee shop might join the Wi-Fi without asking. This gives them free internet without using their own data.

But piggybacking isn’t just about Wi-Fi. In data transmission, it means using the channel effectively. By adding acknowledgments to data frames, it uses network resources better. This method is about making the most out of what’s available.

Piggybacking and bandwidth

Piggybacking is a clever method used in data transmission. It makes things more efficient and uses network space better. It works by joining acknowledgments to the next data frame.

This means we don’t need a separate step just for acknowledgments. By doing this, the network runs better and has less traffic.

When some people say piggybacking, they might be talking about something else. They might mean using someone’s Wi-Fi without asking, which is wrong. The piggybacking we’re discussing is about making better use of the network’s space, not about breaking the rules.

Differences between piggybacking and tailgating

Piggybacking and tailgating are different ways people try to get into places they shouldn’t be. They sound pretty similar but have key differences:


Piggybacking is when someone tricks their way into a restricted area by fooling others. They might pretend to be a maintenance worker or act like a trusted employee. By doing this, they take advantage of people’s natural desire to be helpful. This method isn’t just about hacking Wi-Fi. It’s also about using social skills to overcome physical security.


Tailgating, on the other hand, is all about sneaking into a secure area by closely following an authorised person. The goal is to get past security by going in with someone who has the right to be there. For example, it happens when one person opens a secure door and then someone else slips in without being checked. It relies on taking advantage of people’s good nature or their lapse in attention.

So, piggybacking tricks a helpful person into letting someone in, while tailgating means sneaking in right behind someone who can go in. Though people might mix these two up, knowing what makes them different is key to stopping unauthorised access.

Examples of piggybacking

Piggybacking happens in several common situations. For example:

  • Connecting to unprotected Wi-Fi in businesses like coffee shops from outside is common.
  • It occurs when network passwords are known by many, like when a coffee shop posts them.
  • Using personal hotspots with weak security can make you a target.
  • And if home routers have easy-to-guess passwords, they are at risk too.

It’s clear that securing Wi-Fi networks well and using strong passwords is vital. This helps stop others from using your network without permission. Everyone, both businesses and people at home, needs to act to keep their information safe from piggybacking threats.

Piggybacking security: How to prevent piggybacking attacks

To protect against piggybacking attacks and keep your Wi-Fi safe, following strong security steps is key. These steps help lower the chance of someone getting onto your network without permission. They include steps like creating strong Wi-Fi passwords and changing them often.

  1. Create Strong Wi-Fi Passwords: Make sure your Wi-Fi passwords are not easy to guess. Use a mix of random letters, symbols, and numbers. Don’t pick passwords like “password” or “123456”.
  2. Change Passwords Regularly: Change your Wi-Fi password often. This stops others from using it if they somehow find out what it is. When you change the password, their access is cut off too.
  3. Monitor Connected Devices: Always keep an eye on who’s connected to your Wi-Fi. Look for any devices you don’t know. If you find one, investigate and kick it off your network immediately.
  4. Educate Network Users: Teach everyone who uses your Wi-Fi about piggybacking risks and how to use Wi-Fi safely. Tell them to use strong passwords, not to share them publicly, and to tell you if they see anything strange.

By using these steps, you make it harder for someone to piggyback on your Wi-Fi. This helps keep your data safe.

The concept of piggybacking in cyber security

In the world of cyber security, piggybacking is when someone sneaks into a secure area. This happens when an unauthorised user follows an authorised one through a locked door. Or, they may steal login details to get into a computer system. It shows why we must always be alert about who we let in and how we protect our information.

How piggybacking works in cyber security

In cyber security, piggybacking is when someone uses tricks to get into places they shouldn’t. This might be a building or a computer system. They do this by either finding security holes or copying how someone else gets in.

  1. Gaining physical access to the target premises
  2. Observing an authorized person authenticating to a restricted system
  3. Mimicking credentials by obtaining login credentials
  4. Accessing the system using the stolen credentials
  5. Covering tracks to avoid detection
  6. Maintaining unauthorized access

Piggybacking plays on both weak spots in security and the kindness of people. By physically getting into a secure area and seeing how others log in, a wrongdoer can copy this. Then they can get into systems or places they shouldn’t be in.

For companies, fixing security gaps and controlling access is key to stopping piggybacking. They should train their staff to always be alert and stick to security rules. This helps lower the chances of sneaky access by others.

Examples of piggybacking in cyber security

Piggybacking in cyber security happens in many ways. It uses common tricks to sneak into secured areas or systems. By knowing these tricks, we can work to stop them. This makes things safer for all.

1. Tailgating into Secure Areas

Tailgating is when someone gets into a secure place by walking in behind someone else. An attacker might hide near a building. Then they enter as soon as someone with an access card goes in. This way, they use the cardholder’s permission to get in.

2. Credential Theft

Stealing login details is another piggybacking trick. It lets someone get into systems they shouldn’t. They might trick people into sharing their details. Or find weak spots in security to get usernames and passwords.

3. Exploiting Social Engineering

Attackers can also take advantage of helpful behaviours, like holding doors open. They might act like they belong or are trusted to get into a secure place. They trick people into letting them in by seeming trustworthy. This way, they use others’ trust to get what they want.

4. Wireless Network Intrusion

Getting into Wi-Fi networks without permission is a form of piggybacking too. Attackers look for weak spots in networks. Or they might steal login details. This can let them see and maybe use private data shared over the network.

Knowing about these piggybacking dangers helps. We can do things like make physical places more secure. Use more than one way to check who gets in. Teach people how to spot bad tricks. And make sure our networks are very strong.

Preventing Wi-Fi Piggybacking Attacks

To stop Wi-Fi piggybacking attacks and keep your network safe, there are crucial steps to follow:

  1. Create long and hard-to-guess passwords for your Wi-Fi network. Make sure these passwords are not simple and are kept secret. This way, it’s harder for unauthorised users to enter your network.
  2. Change your Wi-Fi password from time to time. This prevents piggybackers from keeping access if they got in without permission.
  3. Keep an eye on who’s using your network. If you see devices you don’t know, kick them off. This ensures that only trusted devices connect.
  4. Protect your Wi-Fi with encryption. WPA2 or WPA3 encryption adds a layer of security. It makes it tough for attackers to understand your data.
  5. Think about hiding your Wi-Fi network’s name (SSID). Turning off SSID broadcast means your network is harder to find. This can discourage potential piggybackers.
  6. Always update your router’s software and security features. Updates fix problems and make it harder for attackers to get in.

By sticking to these steps and setting up strong security, you lessen the risk of Wi-Fi piggybacking. This keeps your Wi-Fi network safe.

The advantages of piggybacking

Piggybacking is a smart way to boost network performance. It lets acknowledgments travel with data frames. So, there’s no need for extra trips just for acknowledgments. This cuts down on network traffic and makes things run smoother.

One big plus of piggybacking is how it slashes down on waiting time. Usually, nods of acknowledgment take their own route. With piggybacking, they hitch a ride, making messages arrive faster. This makes the network feel more instant to users.

Piggybacking also saves money and network space. Say goodbye to extra trips for acknowledgments. This is great for places using a lot of two-way data journeys. Piggybacking makes such trips more efficient.

Adding to this, piggybacking uses the full power of the network. Mixing acknowledgment trips with data journeys uses the space better. This is a big win when network space is tight or costly.

Summing it all up, piggybacking offers many pluses. It boosts how networks work, cuts down on travel, saves money, uses space wiser, and makes the network feel snappier. By making data and nods travel together, piggybacking is a clever, pocket-friendly choice for all.

The disadvantages of piggybacking

Using piggybacking in networks has its benefits, like being more efficient. But, there are serious downsides to this method as well. One big issue is how it makes network protocols more complicated.

When piggybacking is used, both sending and receiving parties must match their actions closely. They have to make sure data gets transmitted efficiently. If not, problems like delays and having to send the same data again can happen.

Finding and fixing problems can also get harder with piggybacking. The extra steps involved make troubleshooting more complex. This can slow down how quickly issues are solved in network communications.

Drawbacks of piggybacking:

  1. Additional complexity in network protocols
  2. Potential for delayed or rebroadcasted frames
  3. Challenges in troubleshooting and debugging

These challenges mean network experts need to think carefully about piggybacking. They must decide if the good points are really worth the problems it brings.


Piggybacking has different meanings in networking and cyber security. In networking, it’s about making data flow more efficiently. This happens when acknowledgments are added to data frames. It’s a way to use the channel bandwidth better.

In cyber security, piggybacking means sneaking into a network or place you shouldn’t be. This is done by either finding security holes or acting like you have permission. But no matter the case, piggybacking is risky and can open the door to threats.

To keep networks and systems safe, stopping piggybacking is key. Use strong passwords, and watch devices that connect to your network. Also, teach everyone about staying safe online and why it matters.

By knowing about piggybacking and taking steps to stop it, we protect what’s important to us. Stay alert, learn about new ways to stay secure, and keep making your security measures better. This way, we can try to outsmart those who might want to do harm.
