Cryptography and Network Security Quiz

Cryptography in Computer Data Security

• Ensures confidentiality, integrity, and authenticity of data.
• Encrypts sensitive information, making it unreadable to unauthorized users.
• Utilizes algorithms and keys for secure communication and storage.

Primary Focus of Computer Security

• Protects individual devices from unauthorized access and attacks.
• Focuses on safeguarding data integrity, confidentiality, and availability on physical hardware.
• Encompasses measures such as firewalls, antivirus software, and access controls.

Contribution of Cryptography to Data Protection

• Facilitates secure transactions by encrypting sensitive data like credit card information.
• Ensures message integrity through hashing methods, preventing tampering.
• Provides digital signatures verifying the authenticity of the sender.

Primary Concern of Network Security

• Protecting data during transfer across networks from threats and unauthorized access.
• Addresses vulnerabilities in network infrastructure such as routers and switches.
• Employs measures like firewalls, intrusion detection systems, and secure protocols.

Difference Between Computer Security and Network Security

• Computer security focuses on individual devices, while network security emphasizes data in transit.
• Computer security addresses threats to local systems (e.g., malware), whereas network security targets threats infiltrating from external sources.
• Both complement each other but have distinct operational scopes and vulnerabilities.
