- Application Security: Ensuring applications are designed and maintained securely.
- Data Protection: Safeguarding data through encryption and access controls.
- Identity and Access Management: Managing user identities and access to resources.
Cybersecurity is the practice of protecting computers, networks, and data from unauthorized access
Protecting computers, networks, and data from unauthorized access is a complex task that involves multiple layers of security. Cybersecurity is not just about technology; it's also about people and processes. It requires a comprehensive approach to safeguard against various digital threats.
The Scope of Protection in Cybersecurity
The scope of cybersecurity is broad, encompassing several key areas. It includes protecting networks and systems from unauthorized access, ensuring the integrity and confidentiality of data, and implementing measures to detect and respond to cyber threats. Cybersecurity also involves educating users about security best practices to prevent human error from compromising security.
Preventive vs. Detective Security Measures
| Measure Type | Description | Examples |
|---|---|---|
| Preventive | Stop cyber threats before they occur | Firewalls, Intrusion Prevention Systems, Encryption |
| Detective | Identify and respond to cyber threats | Intrusion Detection Systems, Security Monitoring, Incident Response Planning |
Common Cyber Threats in Today's Digital Landscape
Malware Types and Their Impact
- Viruses and Worms: Attach to clean files or self-replicate, causing disruption.
- Ransomware: Encrypts files and demands ransom.
- Spyware: Secretly monitors user activity for malicious purposes.
Social Engineering Attacks
- Phishing: Fraudulent messages trick users into revealing sensitive data.
- Pretexting: Creating a false scenario to gain trust.
- Baiting: Luring victims with a false promise or reward.
Network Security: Safeguarding Communication Channels
- Firewall Implementation and Management – First line of defense controlling network traffic.
- Secure Network Architectures – Using VLANs, VPNs, and segmentation.
