📌 Security Log Analysis Summary
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.
🙋🏻♂️ Explain Security Log Analysis Simply
Imagine a security guard checks a list every time someone enters or leaves a building. Security log analysis is like reading through this list to spot anything unusual, like someone entering at odd hours. By looking for strange patterns or unexpected visitors, you can catch problems early and keep the building safe.
📅 How Can it be used?
Security log analysis can be used in a project to detect unauthorised access attempts on a company’s web servers.
🗺️ Real World Examples
A hospital IT team regularly reviews security logs from their patient records system to spot failed login attempts or unusual access patterns, helping them quickly identify if someone is trying to access sensitive medical information without permission.
A retail company uses automated log analysis to monitor its payment processing systems, alerting staff when there are repeated failed payment attempts or suspicious transactions that could indicate fraud or hacking activity.
✅ FAQ
What is security log analysis and why is it important?
Security log analysis is the process of looking at records created by computers, applications, and network devices to spot any unusual or unauthorised activity. These records, or logs, show things like who logged in, what files were accessed, and any changes made to systems. By reviewing these logs, organisations can notice problems early, investigate security incidents, and meet legal requirements for keeping data safe.
How can security log analysis help prevent cyber attacks?
By regularly examining logs, organisations can catch warning signs of trouble, such as failed login attempts or unexpected changes to important files. This early detection means they can respond quickly before an attacker causes serious damage. Over time, analysing these logs also helps spot patterns that could point to weaknesses in the system, making it easier to strengthen defences against future threats.
What types of events are usually recorded in security logs?
Security logs usually capture a wide range of activities, including when users log in or out, changes to system settings, access to sensitive files, and software installations. They might also record network connections and attempts to access restricted areas. By keeping track of these events, organisations create a useful record that can be checked if something goes wrong or needs to be investigated.

Tokenisation Strategies
Tokenisation strategies are methods used to split text into smaller pieces called tokens, which can be words, characters, or subwords. These strategies help computers process and understand language by breaking it down into more manageable parts. The choice of strategy can affect how well a computer model understands and generates text, as different languages and tasks may require different approaches.
Network Segmentation
Network segmentation is the practice of dividing a computer network into smaller, isolated sections. Each segment can have its own security rules and access controls, which helps limit the spread of threats and improves performance. By separating sensitive systems from general traffic, organisations can better manage who has access to what.
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.
AI-Driven Insights
AI-driven insights are conclusions or patterns identified using artificial intelligence technologies, often from large sets of data. These insights help people and organisations make better decisions by highlighting trends or predicting outcomes that might not be obvious otherwise. The process usually involves algorithms analysing data to find meaningful information quickly and accurately.
Procure-to-Pay Automation
Procure-to-Pay Automation refers to the use of technology to streamline and automate the entire process of purchasing goods or services and paying suppliers. This includes everything from requesting a purchase, getting approvals, placing orders, receiving goods, and processing invoices, to making payments. Automating these steps helps organisations save time, reduce errors, and improve transparency in their purchasing activities.
