📌 Security Information and Event Management (SIEM) Summary

Security Information and Event Management (SIEM) is a technology that helps organisations monitor and analyse security events across their IT systems. It gathers data from various sources like servers, applications, and network devices, then looks for patterns that might indicate a security problem. SIEM solutions help security teams detect, investigate, and respond to threats more quickly and efficiently by providing a central place to view and manage security alerts.

🙋🏻‍♂️ Explain Security Information and Event Management (SIEM) Simply

Imagine a security guard watching lots of CCTV cameras at once. Instead of checking each one separately, the guard uses a big screen that shows all the important activity and highlights anything suspicious. SIEM works like that big screen, helping IT teams spot and respond to problems quickly, rather than missing something important happening in the background.

📅 How Can it be used?

A company can use SIEM software to automatically detect and alert staff to suspicious activity on its network.

🗺️ Real World Examples

A financial institution uses SIEM to monitor login attempts across its systems. When the SIEM detects a pattern of failed logins from an unusual location, it triggers an alert and the security team investigates, preventing a possible data breach.

A hospital uses SIEM to track access to patient records. If the SIEM notices that a staff member is accessing an unusually high number of records in a short time, it flags this for review, helping to prevent unauthorised access or data misuse.

✅ FAQ

A SIEM system acts like a security control room for your organisation. It collects information from across your IT systems, such as servers and network devices, and helps spot anything out of the ordinary. By putting all the data in one place, it makes it much easier for security teams to notice problems early and respond quickly before they turn into bigger issues.

SIEM is important because it helps organisations keep an eye on their digital environment and catch threats that might otherwise go unnoticed. Whether a company is large or small, cyber attacks and data breaches can cause serious problems. SIEM systems help by providing alerts and insights, so teams can act fast and limit any damage.

When a potential security issue is detected, a SIEM system sends alerts and gathers all the relevant details in one place. This helps security teams quickly investigate what happened and decide what steps to take. By making it easier to see the full picture, SIEM systems speed up the response and help prevent similar incidents in the future.

VPN Split Tunneling

VPN split tunnelling is a feature that lets you choose which internet traffic goes through your VPN connection and which uses your regular internet. Instead of sending all data through the secure VPN, you can decide that only specific apps or websites use the VPN, while the rest connect directly. This helps balance privacy with speed and access to local services.

Statechain Protocols

Statechain protocols are a type of cryptographic technology designed to transfer ownership of digital assets, such as Bitcoin, without moving them on the public blockchain. Instead, control over the asset is passed between parties using a secure chain of signatures and encrypted messages, which are verified by a trusted server called a statechain entity. This approach allows for quicker and cheaper transactions by reducing the need for on-chain activity, while still maintaining security and privacy.

Secure Multi-Party Computation

Secure Multi-Party Computation, or MPC, is a technology that allows several parties to work together on a calculation or analysis without any of them having to share their private data with the others. Each participant keeps their own information secret while still contributing to the final result. This approach is used to protect sensitive data during joint computations, such as financial transactions or medical research, where privacy is important.

Feature Engineering

Feature engineering is the process of transforming raw data into meaningful inputs that improve the performance of machine learning models. It involves selecting, modifying, or creating new variables, known as features, that help algorithms understand patterns in the data. Good feature engineering can make a significant difference in how well a model predicts outcomes or classifies information.

Bias Control

Bias control refers to the methods and processes used to reduce or manage bias in data, research, or decision-making. Bias can cause unfair or inaccurate outcomes, so controlling it helps ensure results are more reliable and objective. Techniques for bias control include careful data collection, using diverse datasets, and applying statistical methods to minimise unwanted influence.
