Study Notes
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.
