System administration

System administration is essential to cyber security, ensuring that computer systems are managed effectively and remain safe to use. It involves overseeing and managing computers, networks, and user access so that systems are reliable and secure. System administrators set up security controls, keep software up to date, manage user accounts, and monitor systems for suspicious activity. This helps to reduce risks and protect data. Without proper administration, systems can become outdated, misconfigured, or vulnerable to threats such as malware or unauthorised access. By regularly maintaining and securing systems, administrators play a critical role in preventing cyber threats and keeping digital environments running smoothly.
