📌 Data Encryption at Rest Summary
Data encryption at rest is a security method that protects stored data by converting it into unreadable code. Only someone with the correct key can turn the data back into its original form. This process helps stop unauthorised people from accessing the information if storage devices are stolen or hacked.
🙋🏻♂️ Explain Data Encryption at Rest Simply
Imagine locking your diary in a safe when you are not using it. Even if someone finds the safe, they cannot read your diary without the right key. Data encryption at rest works the same way, keeping information protected even when it is not being used.
📅 How Can it be used?
Encrypting database files on a server ensures confidential customer details remain protected if the server is stolen or breached.
🗺️ Real World Examples
A hospital stores patient records on its servers. To keep this sensitive information private, the hospital uses encryption at rest so that only authorised staff can access the records, even if someone gains physical access to the server.
A cloud storage provider automatically encrypts all uploaded files on its servers. This means that if someone gains unauthorised access to the storage hardware, the files remain unreadable without the proper decryption keys.
✅ FAQ
What does data encryption at rest mean?
Data encryption at rest means turning stored information into unreadable code so that only someone with the right key can see the original data. This protects your files if a computer or hard drive is lost or stolen.
Why is it important to encrypt data that is just sitting in storage?
Even if data is not being used, it can still be a target for thieves or hackers. Encrypting data while it is stored helps keep your information safe, making it much harder for anyone without permission to read it if they manage to get hold of your device.
Can encryption at rest slow down my computer or phone?
Most modern devices are designed to handle encryption without noticeable slowdowns. You are unlikely to see much difference in everyday use, and the extra layer of security is worth it for the protection it offers.

Cloud Data Sovereignty
Cloud data sovereignty means that digital information stored in the cloud is subject to the laws and regulations of the country where it is physically located. This affects how data can be accessed, shared, and protected by governments and organisations. Companies using cloud services must ensure that their data storage and processing comply with local and international rules, which can vary widely between countries.
Model Pruning
Model pruning is a technique used in machine learning where unnecessary or less important parts of a neural network are removed. This helps reduce the size and complexity of the model without significantly affecting its accuracy. By cutting out these parts, models can run faster and require less memory, making them easier to use on devices with limited resources.
Compliance Dashboarding
Compliance dashboarding is the process of using visual tools and software dashboards to monitor and report on an organisation's adherence to legal, regulatory, or internal compliance standards. These dashboards display real-time data and key metrics, making it easier for teams to track compliance status and identify potential issues quickly. By centralising compliance information, organisations can improve transparency, reduce manual reporting, and respond faster to risks or regulatory changes.
Output Poisoning Risks
Output poisoning risks refer to the dangers that arise when the results or responses generated by a system, such as an AI model, are intentionally manipulated or corrupted. This can happen if someone feeds misleading information into the system or tampers with its outputs to cause harm or confusion. Such risks can undermine trust in the system and lead to incorrect decisions or actions based on faulty outputs.
Security Log Analysis
Security log analysis is the process of reviewing and interpreting records generated by computer systems, applications, and network devices to identify signs of suspicious or unauthorised activity. These logs capture events such as user logins, file access, or system changes, providing a trail of what has happened on a system. Analysing these logs helps organisations detect security incidents, investigate breaches, and comply with regulations.
