The training and skills medium
A firewall is a security system (software or hardware) designed to monitor, filter and control the flow of data in and out of a network or computer system.
It acts as a protective barrier between a secure internal network and untrusted external sources (such as the Internet), applying predefined rules to block unauthorised access or potential threats.
A brute force attack is a hacking method that involves testing a large number of combinations of passwords, encryption keys or identifiers until the correct one is found.
This technique is based on trial and error and can be used to access user accounts, computer systems or encrypted data. This approach relies on computing power (human or automated) rather than software flaws.
In cyber security, governance is the set of processes, policies and structures designed to align IT security with organisational objectives, in order to protect systems and data while ensuring regulatory compliance.
In a Microsoft Windows environment, a Group Policy Object (GPO) is a set of rules and settings applicable to users or computers within a network. It enables system administrators to control and standardise configurations, security policies and system behaviour via Active Directory.
