Cyber Security
This is the collective practice of protecting systems, networks and data from digital attacks. The world is becoming more dependent on the cyber space and its interconnectivity is getting greater, hence the need for these defences cannot be over emphasized; to prevent financial loss, identity theft, and the disruption of critical infrastructure like power grids.
Effective cyber defence is multi-layered cutting across different digital environments.
Types of Cybersecurity
Network Security
This secures computer networks from intruders and targeted attacks using firewalls and encryption.
Cloud Security
This deals with protecting data, applications, and infrastructure hosted on cloud platforms like AWS (warning systems) or Azure.
Endpoint Security
This defends individual devices like laptops, smartphones, and tablets from malware and unauthorized access.
Application Security
Deals with protecting software free of threats by fixing vulnerabilities during the design and development stage.
Critical Infrastructure Security
This protects and preserves the important systems society depends on, e.g. energy, healthcare and transportation.
