7 Smart Ways to Secure Your Wireless Printer & Keep Your Home Network Safe

Tanya Wetson-Catt • 8 June 2023

Many people worry about someone hacking their computer. But they’re not really thinking about their wireless printer getting breached. It’s a tool that most individuals use

sporadically. For example, when you want to print out tax forms or mailing labels.


Printers tend to be out of sight, out of mind. That is until you need to print something and run out of ink. Well, they’re not out of the mind of hackers. In fact, unsecured printers are a classic way for criminals to gain access to a home network.


To illustrate this point, Cybernews purposely hacked printers. It hijacked nearly 28,000 unsecured printers globally. The success rate was 56%. What did it do once it gained access? Ironically, it made the printers print out a guide on printer security.


Are you wondering how exposed your network is from your printer? We’ve got some security tips below to help. These tips can enable you to better secure your network, which keeps data on all devices more secure.


1. Change the Default Login Credentials


When you buy a new printer, it will likely have included default information. Manufacturers give you a way to connect and set up your device. This usually involves default login information.


Immediately change that information during set up. Hackers use a master list of all these defaults. They plug it into an automated script and just keep trying them all until they get a hit. Change these, and make sure you create a strong password.


2. Keep Printer Firmware Updated


Keeping firmware updated is vital to keeping your printer secure. Hardware needs updating just like computers, software, and apps do. Those updates often contain important security patches.


Firmware updates aren’t usually as visible as software updates. Software and OS updates usually give you a popup notification. But updates to the drivers and firmware that run printers, aren’t so visible.


Some of the places you can check for firmware updates are:


  • The PC manufacturer’s utility app on a connected device
  • The printer’s information panel
  • The printer manufacturer’s app installed on a PC


3. Use a Network Firewall


A network firewall is important to ensure the monitoring of traffic. Firewalls can block suspicious activity to keep hackers out of your network. You should configure the firewall to watch incoming and outgoing printer traffic.


4. Put Your Printer on a Guest Network


Most of today’s home routers allow you to set up a guest network. This is a separate Wi-Fi that runs from the same router you use for your main network. It’s harder for hackers to get from one network to another.


Keeping a less secure device separated from computers and phones improves security. You can still print to your printer from devices on another network. You just need to have things configured correctly. If you need help with that, just let us know. 


5. Disable Unused Ports or Services


IoT devices, like printers, often have many ways to connect. You may not need all the ports or services that come with your printer. These ports are risk areas where hackers could find a way in.


It’s best to disable any ports and sharing features that you don’t need. This reduces the risk of a breach.


6. Unplug It When Not in Use


Most home printers aren’t used as much as work printers. People may only use them once a month or a few times a year. If you’re not using your printer constantly, unplug it when not in use.


One surefire way to cut off a hacker’s access is to unplug the device. When it’s shut down, no access is available at all. 


7. Teach Your Family Cybersecurity Best Practices


Your printer is one device on your network. Most families connect several devices to their home Wi-Fi. In 2022, the average number of connected devices per U.S. household was 22.  


Families need to know and adopt good cyber habits. This keeps everyone’s data more secure. It also helps you avoid costly identity theft breaches. Or the takeover of things like baby monitors.


Some standard best practices to follow for good cyber hygiene are:


  • Always use strong passwords. (at least 10-12 characters & include a mix of letters, numbers, and symbols)
  • Keep software & firmware on devices updated
  • Use multi-factor authentication wherever possible
  • Enable device firewalls & other protections
  • All devices that should have a good antivirus installed
  • Never login to an account from a link you receive via email or text
  • Learn how to identify phishing & get a second opinion before clicking
  • Get a security checkup from a pro at least every year or two

Best Practices for Secure Data Backup

by Tanya Wetson-Catt • 21 February 2025
These days, everything is digital. We deal with data every day: from personal photos to work files that hold a lot of value. What happens if you lose that? Well, this is the reason behind doing secure backups of data. Let’s go through some best practices to keep your data safe and secure. What is Data Backup? Data backup refers to the creation of a copy of your data. The copy can be used in the event of loss or destruction of the original data. Backups can be stored on various devices, such as external hard drives, or in the cloud. Having a backup ensures you don’t lose important information. Why Is Secure Backup Important? Backing up will save your data from being lost forever. Sometimes computers crash, or get viruses. Other times, you may delete some important files accidentally. If you do not have a backup, then you could lose everything. Backing up your data keeps it safe from these problems. How Often Should You Back Up Your Data? Backing up your data is very important and should be done regularly. Some people back up their data every day, while others do it on a weekly basis. It depends on how often your data changes. If you have important files that change daily, then you should back them up every day. Regular backups mean you will always have the latest version of your files. What Are The Different Types of Backups? There are several types of backups you can use: Full Backup A full backup copies all your data. It takes more time and space but is very thorough. Incremental Backup An incremental backup only copies new or changed files since the last backup. It saves time and space. Differential Backup A differential backup copies all changes made since the last full backup. It’s faster than a full backup but takes more space than an incremental one. Where to Store Your Backups? The place of storage for your backups is an important consideration: External Hard Drives These are physical devices you can store at home or at work. It’s convenient, but they can get lost or damaged. Cloud Storage It keeps your backups online, so it is safe from any form of physical damage. It’s also easily accessible from any location. Offsite Storage Offsite storage means keeping backups in a different location than your main data. This protects against theft or natural disasters. How Can You Ensure Your Backups Are Secure? Keeping your backups secure is as important as making them: Use Encryption Encryption scrambles your data so only you can read it. This keeps it safe from hackers. Set Strong Passwords Use strong passwords for all your backup accounts and devices. This prevents unauthorised access. Regularly Test Your Backups Testing ensures that your backups work properly. Try restoring a file to make sure everything is correct. What Tools Can Help With Data Backup? Many tools can help automate and manage backups: Backup Software Backup software can schedule and perform backups automatically. This makes it easier to keep up with regular backups. Cloud Services Many cloud services include automatic backups in their package. They provide extra security features too. What Should You Avoid In Data Backup? Here are some of the common mistakes to avoid while backing up your data: Not Having Multiple Copies Always have more than one copy of your backup in different places. Ignoring Security Updates Keep all backup software and devices updated to protect against new threats. How Can You Make A Backup Plan? Creating a backup plan helps you get organised by: Determining what data should be backed up. Frequency of backups. Where the backups will be located. Reminders to test regularly.

Can Password Managers Be Hacked?

by Tanya Wetson-Catt • 17 February 2025
Password managers keep our online accounts safe. They store all our passwords in one place. But are they hackable? What are Password Managers? Password managers are like digital vaults: they save all your passwords inside themselves. You need only remember one master password, of course. This makes keeping a lot of accounts much easier to handle. How Do They Work? You make one main password. The manager scrambles your passwords. What this means is, it changes them into an unreadable format without a key. Why Use Them? People use password managers out of convenience and security. One single factor is the difficulty in remembering several strong passwords. A password manager allows you to generate and securely store all these. Can Password Managers be Hacked? They always hunt for ways to steal your information. However, breaking into a password manager is not easy. Security Measures Password managers use very strong encryption. This makes them barely readable by hackers. They are also using two-factor authentication-2FA. The addition of this adds a layer of security. No system is perfect. If a hacker gets your master password, then they can access your vault. A few managers have had security issues in the past, but these are rare. How Can You Protect Your Password Manager? You can take steps to keep your password manager safe. Choose a Strong Master Password Make your master password long and unique. Use a mix of letters, numbers, and symbols. Enable Two-Factor Authentication 2FA adds a layer of security. Even if someone knows your password, they need another code to log in. Keep Software Up-to-Date Always update your password manager. Updates fix security issues and keep your data safe. What Happens If a Password Manager Gets Hacked? If a password manager gets hacked, it can be serious. Hackers could access all your passwords. Immediate Actions Change your master password immediately. Decide which accounts could be affected and change their passwords as well. Long-Term Solutions Consider shifting to another password manager if it has been compromised anytime earlier. Keep up to date with any security news about your manager. Is the Use of Password Managers Worth the Risks? Despite the risks, many people still use password managers. They make managing passwords much easier. It’s also safer than trying to remember them all yourself. Benefits Outweigh Risks The benefits of using a password manager usually outweigh the risks. They help you create strong, unique passwords for each account. Trustworthy Options Choose a reputable password manager with good reviews and security features. Do some research before deciding which one to use. Take Control of Your Online Security Today! Using a password manager will go a long way in enhancing your online security.

Ultimate Guide to Encryption Methods

by Tanya Wetson-Catt • 14 February 2025
Encryption is a method of securing information. It converts readable data into secret code. Only the right key can decode it. This guide will help you understand different encryption methods. What is Encryption? Encryption is like a secret language. It converts regular text into unreadable text. This unreadable text is called ciphertext. Only people who have the right key will be able to convert it into normal text, called plaintext. Why Do We Use Encryption? We use encryption to keep our information safe. It makes our data safe from hackers. This is very important for privacy and security. How does Encryption Work? Encryption uses algorithms and keys. An algorithm is a set of rules for solving problems. A key is somewhat like a password that unlocks the secret message. Symmetric vs Asymmetric Encryption There are two main types of encryption: symmetric and asymmetric. Symmetric encryption uses the same key for encryption and decryption. The same key is shared between the sender and receiver. It’s fast but less secure when the key is shared. Asymmetric encryption uses two keys: a public key and a private key. A public key can encrypt a message, while a private key can decrypt it. It’s more secure since only the private key unlocks the message. What Are Some Common Encryption Methods? There are numerous encryption methods in use today. Here are some of the most common ones: AES (Advanced Encryption Standard) AES is one of the most secure forms of encryption. It is symmetric encryption. AES can have 128, 192, or 256-bit keys. The longer the key, the harder it is to break. RSA (Rivest-Shamir-Adleman) RSA is an asymmetric encryption method. It uses two keys: a public and a private key. RSA is widely used for secure data transmission. DES (Data Encryption Standard) DES was once a popular symmetric encryption method. It uses a 56-bit key, which is now considered weak. DES has mostly been replaced by AES. ECC (Elliptic Curve Cryptography) ECC is an asymmetric technique that offers better security and more compact key sizes. It is efficient and widely adopted in various mobile gadgets. How Do We Use Encryption in Everyday Life? Encryption plays a major role in our daily life routines. Online Shopping When you purchase online, your payment information is encrypted. This protects your credit card information against hackers. Messaging Apps Apps like WhatsApp use encryption to keep your messages private. Only you and the person you are chatting with can read them. Email Security Many email services use encryption to protect your emails from being read by others. What Are the Challenges of Encryption? Encryption has many benefits, but it also faces challenges. Key Management Managing keys securely is a challenge. If some person loses their key, they probably will lose their data. Performance Issues Encryption could slow down the systems since it needs processing power for encryption and decryption. How Can You Stay Safe with Encryption? You can take some steps to securely use encryption. Use Strong Passwords Always use strong passwords for accounts and devices. That will make hacking difficult as it will take time to access. Keep Software Up-to-Date Regularly update your software to protect against security vulnerabilities in software. Use Caution with Public Wi-Fi If you need to use public Wi-Fi, avoid sensitive transactions unless you can encrypt your internet connection using a VPN. Ready to Secure Your Data? Encryption helps protect your personal information from threats. Understanding different methods can help you choose the right one for your needs.
