Study Notes
Importance of Data Security
- Data security is crucial to protect an organization's critical assets from unauthorized access, modification, use, destruction, and corruption.
- Failure to protect data can result in lawsuit cases, huge fines, and damage to an organization's reputation.
Definition of Data Security
- Data security is about protecting information from unauthorized access, modification, use, destruction, and corruption.
- It covers both electronic and physical protection of data.
Importance of Data Protection
- Data is a valuable asset that needs to be protected from corruption and unauthorized access to prevent financial loss, reputation damage, consumer confidence disintegration, and brand erosion.
- Government and industry regulations make it imperative for organizations to achieve and maintain compliance with data security rules.
Data Security Technologies
- Data encryption applies a code to every individual piece of data, making it unreadable without an authorized key.
- Data encryption software uses an algorithm and an encryption key to turn normal text into encrypted cipher text.
- Data masking protects data from disclosure to external malicious sources and internal personnel with malicious intent.
- Data erasure is necessary to permanently delete data that is no longer active or used.
- Data resilience involves creating backup copies of data to recover it in case of accidental erasure or corruption.
Access Control and Authentication
- Authentication and authorization occur through access control, ensuring that data access is given only to authorized persons based on their role.
- Access control systems include discretionary access control, role-based access control, and mandatory access control.
Data Security Standards and Compliance
- Data breaches have occurred due to poor implementation or absence of security controls in private companies and government organizations.
- Countries are working to improve security requirements and implementing them in their legislation.
- Compliance regulations, such as GDPR and HIPAA, govern organizations dealing with personal data, and failure to comply can result in penalties and fines.
