📌 Attack Surface Summary
An attack surface is the total number of ways an attacker can try to gain unauthorised access to a computer system, network, or application. It includes all the points where someone could try to enter or extract data, such as websites, software interfaces, hardware devices, and even employees. Reducing the attack surface means closing or protecting these points to make it harder for attackers to exploit the system.
🙋🏻♂️ Explain Attack Surface Simply
Imagine your house has doors, windows, and maybe a cat flap. Each one is a way someone could try to get in. The more entry points you have, the more places you have to protect. In computers, the attack surface is like all those doors and windows, and keeping them locked or minimising them helps keep you safe.
📅 How Can it be used?
Regularly review and minimise the number of exposed interfaces and services to reduce potential vulnerabilities in your project.
🗺️ Real World Examples
A company running a public website identifies all the web forms, API endpoints, and admin panels that are accessible from the internet. By reviewing these points and limiting unnecessary access, they reduce the risk of hackers finding a weak spot to exploit.
A software developer removes unused features and closes unnecessary network ports in their application before launch. This reduces the number of ways attackers could break in or exploit the system.
✅ FAQ
What does attack surface mean in simple terms?
Attack surface is a way of describing all the possible entry points where someone might try to break into a system or steal information. This could be anything from a website login page to a person answering the phone at a company. The more ways there are to get in, the bigger the attack surface.
Why is it important to reduce the attack surface?
Reducing the attack surface makes it much harder for someone to find a way in. If there are fewer doors to check, it is less likely that an attacker will find an open one. This helps keep information safe and protects against unwanted access.
How can everyday people help shrink the attack surface?
Everyday people can play a big part by using strong passwords, being careful with emails and links, and keeping software up to date. These simple actions close off some of the common ways attackers try to get in, making it safer for everyone.

Blockchain for Decentralised Storage
Blockchain for decentralised storage uses a network of computers to store data instead of relying on a single company or server. Information is broken into small pieces, encrypted, and distributed across many participants in the network. This approach makes data more secure and less likely to be lost or tampered with, as no single entity controls the storage.
Neural Combinatorial Optimisation
Neural combinatorial optimisation is a method that uses neural networks to solve complex problems where the goal is to find the best combination or arrangement from many possibilities. These problems are often difficult for traditional computers because there are too many options to check one by one. By learning from examples, neural networks can quickly suggest good solutions without needing to test every possible choice.
Contrastive Representation Learning
Contrastive representation learning is a machine learning technique that helps computers learn useful features from data by comparing examples. The main idea is to bring similar items closer together and push dissimilar items further apart in the learned representation space. This approach is especially useful when there are few or no labels for the data, as it relies on the relationships between examples rather than direct supervision.
Social Media Management
Social media management is the process of creating, scheduling, analysing, and engaging with content posted on social media platforms like Facebook, Instagram, Twitter, and LinkedIn. It involves planning posts, responding to messages or comments, and monitoring how audiences interact with shared content. The goal is to build a positive online presence, connect with people, and achieve business or personal objectives by using social media effectively.
Weighted Sampling
Weighted sampling is a method for selecting items from a group where some items are given a higher chance of being chosen than others. Each item is assigned a weight, which indicates its importance or likelihood of selection. This approach is often used when some options are more relevant or common than others, so the sample better reflects real-world proportions.
