📌 Secure Logging Practices Summary
Secure logging practices involve recording system and application events in a way that protects sensitive information and safeguards logs from unauthorised access or tampering. This means ensuring that logs do not contain private data such as passwords or credit card numbers, and that only authorised personnel can view or modify the logs. Secure logging also includes making sure logs are not lost or deleted unexpectedly, so they can be used for troubleshooting and security investigations.
🙋🏻♂️ Explain Secure Logging Practices Simply
Imagine keeping a diary where you write down important things that happen each day, but you make sure not to include secrets that could embarrass or harm you if someone else read it. You also lock the diary in a safe place so only trusted people can open it. Secure logging is like that for computer systems, making sure the record of events is safe and private.
📅 How Can it be used?
Implementing secure logging helps ensure sensitive data is not exposed and logs remain trustworthy for audits or security reviews.
🗺️ Real World Examples
An online banking app uses secure logging by masking account numbers and excluding passwords from its log files. Access to these logs is restricted to authorised security staff only, and all log entries are timestamped and protected from being altered, which helps in investigating suspicious activities without risking customer privacy.
A hospital’s patient management system logs user access and system errors, but ensures that no patient health information appears in the logs. Logs are encrypted and stored on a secure server, allowing compliance teams to audit system use while keeping sensitive data safe from unauthorised viewing.
✅ FAQ
Why is it important to keep logs secure?
Keeping logs secure is vital because they can contain clues about how systems are being used or misused. If someone unauthorised gets access, they could learn about weaknesses or sensitive details. Protecting logs means you can trust them for troubleshooting or security checks without worrying that the information has been changed or stolen.
What kind of information should never be written in logs?
Logs should never contain private details such as passwords, credit card numbers or personal identification information. Storing this kind of data in logs can put people at risk if the logs are ever accessed by the wrong person. Only information that helps understand what happened in the system should be recorded.
How can you make sure that only the right people can see or change logs?
To make sure only authorised people can view or change logs, you can use things like passwords, special permissions or encryption. These steps help keep logs safe from prying eyes and make sure that no one can secretly alter them. This way, logs remain a reliable source of truth when you need to check what happened.

Neural Network Pruning
Neural network pruning is a technique used to reduce the size and complexity of artificial neural networks by removing unnecessary or less important connections, neurons, or layers. This process helps make models smaller and faster without significantly affecting their accuracy. Pruning often follows the training of a large model, where the least useful parts are identified and removed to optimise performance and efficiency.
Meeting Transcripts
Meeting transcripts are written records of what was said during a meeting. They capture conversations, decisions, and actions in text form, often created from audio recordings or live note-taking. These transcripts help people review discussions, clarify points, and ensure everyone is on the same page, even if they missed the meeting.
Employee Self-Service Apps
Employee self-service apps are digital tools that allow staff to manage work-related tasks on their own, such as requesting leave, updating personal information, or viewing payslips. These apps are often accessed via smartphones or computers, making it easy for employees to handle administrative activities without needing to contact HR directly. By streamlining routine tasks, employee self-service apps can save time for both staff and HR teams.
Emerging Technology Adoption
Emerging technology adoption refers to the process of recognising, evaluating, and integrating new or developing technologies into organisations or everyday life. This often involves assessing potential benefits, costs, and risks associated with the technology. Adoption can be influenced by factors like usefulness, ease of use, readiness, and the willingness of people or groups to try something new.
Procurement Automation
Procurement automation refers to the use of technology to perform repetitive purchasing tasks with minimal human involvement. It streamlines processes such as creating purchase orders, approving invoices, and managing supplier communications. This approach helps organisations save time, reduce errors, and maintain better control over their spending.
