Key Components of Cybersecurity
1. Network Security
Network security involves protecting the integrity and usability of network and data. It includes measures like firewalls, intrusion detection systems (IDS), and virtual private networks (VPNs).
2. Application Security
This focuses on securing software applications from vulnerabilities that hackers might exploit. Regular updates, patch management, and secure coding practices are vital.
3. Endpoint Security
Endpoints such as computers, mobile devices, and servers require protection against malware and unauthorized access.
4. Data Security
Data security involves safeguarding data through encryption, access controls, and backup solutions.
5. Identity and Access Management (IAM)
IAM systems ensure that only authorized individuals can access specific resources, often using authentication methods like passwords, biometrics, or multi-factor authentication (MFA).
6. Security Awareness and Training
Educating users about cybersecurity threats helps prevent social engineering attacks like phishing.
