7 Common Pitfalls When Adopting Zero Trust Security

Tanya Wetson-Catt • 17 June 2024

Zero Trust security is rapidly transforming the cybersecurity landscape. It moves away from traditional perimeter-based security models. In this approach, every connection attempt is continuously verified before granting resource access.


56% of global organizations say adopting Zero Trust is a “Top” or “High” priority.


This approach offers significant security advantages. But the transition process presents several potential pitfalls. Running into these can harm a company’s cybersecurity efforts.

Below, we’ll explore these common roadblocks. We'll also offer guidance on navigating a successful Zero Trust security adoption journey.


Remembering the Basics: What is Zero Trust Security?


Zero Trust throws out the old "castle and moat" security model. The one where everyone inside the network perimeter is trusted. Instead, it assumes everyone and everything is a potential threat. This is true even for users already inside the network. This may sound extreme, but it enforces a rigorous "verify first, access later" approach.


Here are the key pillars of Zero Trust:


  • Least Privilege: Users only get access to the specific resources they need to do their jobs, no more.
  • Continuous Verification: Authentication doesn't happen once. It's an ongoing process. Users and devices are constantly re-evaluated for access rights.
  • Micro-Segmentation: IT divides the network into smaller segments. This limits the damage if a breach occurs.


Common Zero Trust Adoption Mistakes


Zero Trust isn't a magic solution you can simply buy and deploy. Here are some missteps to avoid:


Treating Zero Trust as a Product, Not a Strategy


Some vendors might make Zero Trust sound like a product they can sell you. Don't be fooled! It is a security philosophy that requires a cultural shift within your organisation.


There are many approaches and tools used in a Zero Trust strategy. These include tools like multi-factor authentication (MFA) and advanced threat detection and response.


Focus Only on Technical Controls


Technology indeed plays a crucial role in Zero Trust. But its success hinges on people and processes too. Train your employees on the new security culture and update access control policies. The human element is an important one in any cybersecurity strategy.


Overcomplicating the Process


Don't try to tackle everything at once. This can be overwhelming, and smaller companies may give up. Start with a pilot program focusing on critical areas. Then, gradually expand your Zero Trust deployment bit by bit.


Neglect User Experience


Zero Trust shouldn't create excessive hurdles for legitimate users. Adopting controls like MFA can backfire if employees aren’t involved. Find the right balance between security and a smooth user experience. Use change management to help ease the transition process.


Skipping the Inventory


You can't secure what you don't know exists. Catalogue all your devices, users, and applications before deploying Zero Trust. This helps identify potential access risks. It also provides a roadmap for prioritizing your efforts.


Forgetting Legacy Systems


Don't leave older systems unprotected during your Zero Trust transition. Integrate them into your security framework or consider secure migration plans. Forgotten legacy systems can lead to data breaches that impact your entire network.


Ignoring Third-Party Access


Third-party vendors can be a security weak point. Clearly define access controls and check their activity within your network. Set time-limited access as appropriate.


Remember, Zero Trust is a Journey


Building a robust Zero Trust environment takes time and effort. Here's how to stay on track:


  • Set Realistic Goals: Don't expect overnight success. Define achievable milestones and celebrate progress along the way.
  • Embrace Continuous Monitoring: Security threats are constantly evolving. Continuously watch your Zero Trust system and adjust your strategies as needed.
  • Invest in Employee Training: Empower your employees as active participants in your Zero Trust journey. Regular security awareness training is vital.


The Rewards of a Secure Future


Avoid these common mistakes and adopt a strategic approach. This will enable your business to leverage the big advantages of Zero Trust security. Here's what you can expect:


  • Enhanced Data Protection: Zero Trust minimises the damage from a potential breach. It does this by limiting access to sensitive data.
  • Improved User Experience: Streamlined access controls create a smoother experience for authorised users.
  • Increased Compliance: Zero Trust aligns with many industry regulations and compliance standards.

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. Remember to choose a strong master password. You should also use two-factor authentication and keep your software updated.

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.
