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Data erasure is necessary to permanently delete data that is no longer active or used.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.
