Security technology encompasses a range of tools and systems designed to protect digital and physical assets. Key components include encryption, which secures data by converting it into unreadable code; firewalls, which filter and block unauthorized access to networks; and intrusion detection systems (IDS), which monitor for and respond to suspicious activities. Authentication methods, such as multi-factor authentication (MFA), ensure that only authorized users can access systems. Additionally, secure access controls and biometric systems enhance physical security by verifying individuals’ identities. Regular software updates and patches are crucial for protecting against vulnerabilities. Together, these technologies create a multi-layered defense against various threats and breaches.
