OAuth vulnerabilities are security weaknesses that can occur in applications or systems using the OAuth protocol for authorising user access. These flaws might let attackers bypass permissions, steal access tokens, or impersonate users. Common vulnerabilities include improper redirect URI validation, weak token storage, and insufficient user consent checks.
DNS spoofing is a cyber attack where a hacker tricks a computer into thinking it is connecting to a legitimate website when it is actually being directed to a fake one. This is done by corrupting the Domain Name System (DNS) data used to match website names with the correct servers. As a result, users…
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.
Deep Packet Inspection (DPI) is a method used by network devices to examine the data part and header of packets as they pass through a checkpoint. Unlike basic packet filtering, which only looks at simple information like addresses or port numbers, DPI analyses the actual content within the data packets. This allows systems to identify,…
An air-gapped network is a computer network that is physically isolated from other networks, especially the public internet. This means there are no direct or indirect connections, such as cables or wireless links, between the air-gapped network and outside systems. Air-gapped networks are used to protect sensitive data or critical systems by making it much…
A Man-in-the-Middle Attack is a type of cyber attack where someone secretly intercepts and possibly alters the communication between two parties who believe they are directly communicating with each other. The attacker can read, modify, or inject messages without either party knowing. This can lead to stolen information, such as passwords or credit card numbers,…
Data exfiltration is the unauthorised transfer of data from a computer or network. It often happens when someone gains access to sensitive information and moves it outside the organisation without permission. This can be done through various means, such as email, cloud storage, or portable devices, and is a major concern for businesses and individuals…
Lateral movement is a technique where an attacker, after gaining initial access to a computer or network, moves sideways within the environment to access additional systems or data. This often involves using stolen credentials or exploiting weak security on other devices. The goal is to find valuable information or gain higher privileges without being detected.
Zero Trust Architecture is a security approach that assumes no user or device, inside or outside an organisation’s network, is automatically trustworthy. Every request to access resources must be verified, regardless of where it comes from. This method uses strict identity checks, continuous monitoring, and limits access to only what is needed for each user…
Zero Trust Security is a cybersecurity approach where no user or device is trusted by default, even if they are inside the organisation’s network. Every access request is verified, regardless of where it comes from, and strict authentication is required at every step. This model helps prevent unauthorised access and reduces risks if a hacker…
