Network Traffic Analysis

Network traffic analysis is the process of monitoring, capturing, and examining data packets as they travel across a computer network. This helps identify patterns, detect unusual activity, and ensure that the network is running smoothly. It is used by IT professionals to troubleshoot problems, improve performance, and enhance security by spotting threats or unauthorised access.

Intrusion Detection Systems

Intrusion Detection Systems, or IDS, are security tools designed to monitor computer networks or systems for suspicious activity. They help identify unauthorised access, misuse, or attacks by analysing network traffic or system logs. IDS can alert administrators when unusual behaviour is detected, allowing them to take action to prevent harm or data loss. These systems…

Honeypot Deployment

Honeypot deployment refers to setting up a decoy computer system or network service designed to attract and monitor unauthorised access attempts. The honeypot looks like a real target but contains no valuable data, allowing security teams to observe attacker behaviour without risking genuine assets. By analysing the interactions, organisations can improve their defences and learn…

Application Whitelisting

Application whitelisting is a security approach where only approved or trusted software programmes are allowed to run on a computer or network. Any application not on the approved list is blocked from executing, which helps prevent unauthorised or malicious software from causing harm. This method is commonly used to strengthen security in environments where strict…

Secure Boot

Secure Boot is a security feature that ensures a device only runs software that is trusted by its manufacturer. When a computer starts up, Secure Boot checks each piece of software, such as the operating system and drivers, against a list of approved signatures. If the software has not been approved or has been tampered…

Attack Vector Analysis

Attack Vector Analysis is the process of identifying and understanding the various ways an attacker could gain unauthorised access to a system or data. It involves examining the different paths, weaknesses, or points of entry that could be exploited by cybercriminals. By studying these potential threats, organisations can strengthen defences and reduce the risk of…

Reentrancy Attacks

Reentrancy attacks are a type of security vulnerability found in smart contracts, especially on blockchain platforms like Ethereum. They happen when a contract allows an external contract to call back into the original contract before the first function call is finished. This can let the attacker repeatedly withdraw funds or change the contractnulls state before…

Homomorphic Encryption

Homomorphic encryption is a method of encrypting data so that calculations can be performed on it without needing to decrypt it first. This means sensitive information can remain secure while still being processed or analysed. The results of the calculations, when decrypted, are the same as if they had been performed on the original data….
