Knowra Cybersecurity Cybersecurity Cybersecurity is the practice of protecting digital systems, networks, and data from attack, disruption, or unauthorized access. It combines technical controls, operational procedures, and risk management.
Threat modeling : A structured method for identifying assets, attackers, attack paths, and security requirements. It turns cybersecurity goals into specific risks and defenses before systems are deployed.
Information security : The protection of information against unauthorized access, use, disclosure, disruption, modification, or destruction. Cybersecurity applies information-protection goals to digital systems and connected environments.
Network security : The protection of network infrastructure, traffic, and connected devices from unauthorized access and disruption. It addresses attacks moving across the communications systems that connect digital assets.
Privacy : The ability of people and organizations to control access to information about themselves. Security can protect data without determining whether its collection or use respects privacy.
Data breach : An incident in which sensitive or protected information is accessed or disclosed without authorization. Weak defenses can expose personal, commercial, or government data to outsiders.
Access control : Rules and mechanisms that determine which subjects can use which resources. Restricting permissions limits what compromised accounts and insiders can reach.
Confidentiality, integrity, and availability : The three core security properties of keeping information secret, accurate, and accessible when needed. These properties define what cybersecurity controls are designed to preserve.
Cloud security : The policies and technologies that protect cloud-hosted data, applications, and infrastructure. Cloud services shift security responsibilities across providers, customers, and shared platforms.
Safety engineering : The discipline of preventing accidents and reducing harm from systems and processes. Cybersecurity addresses malicious or unauthorized actions, while safety engineering also handles accidental failures.
Ransomware : Malicious software that blocks access to data or systems, often demanding payment for restoration. It demonstrates how attacks can turn security failures into operational and financial crises.
