Summary 📝

Security measures are important to protect computer systems and data from unauthorised access and cyber attacks. There are several methods that individuals and organisations can use to stay safe. These include using strong passwords, applying user access levels, setting up firewalls, and installing antivirus software. Keeping software updated and making regular backups are also vital steps. These measures help reduce risks from threats like malware and hackers. Each method plays a different role in protecting data. For example, user access levels stop people seeing things they shouldn’t, while firewalls block suspicious connections. Together, these steps help create a secure system.
