Introduction to Data Security Flashcards
Facts and statistics collected for reference or analysis and a key pieces of information.
Data
Protecting digital data, from destructive forces and from the unwanted actions of unauthorized users.
Data Security
Prevent data from being misused by third parties for fraud.
Data Security
Types of Data Security (7)
Access Control
Authentication
Back-up and Recovery
Data Erasure
Data Masking
Data Resiliency
Encryption
This type of data security measures includes limiting both physical and digital access to critical systems and data.
Access Control
Similar to access controls and refers specifically to accurately identifying users before they have access to data.
Ex. passwords, PIN num, biometrics
Authentication
Good data security means you have a plan to securely access data in the event of system failure, disaster, data corruption, or breach and back up data copy
Ex. physical disk, local network, cloud
Back-up and Recovery
-Disposing of data properly and on a regular basis.
-Data wiping.
-Verifies that the data is unrecoverable and therefore won’t fall into the wrong hands.
Data Erasure
Information is hidden by obscuring letters and numbers with proxy characters.
Data Masking
Comprehensive data security means that your systems can endure or recover from failures even in events like power outages or natural disasters won’t compromise security.
Data Resiliency
Computer algorithm transforms text characters into an unreadable format via encryption keys.
Encryption
3 principles of Data Security
Confidentiality
Integrity
Availability
Measures are designed to prevent unauthorized disclosure of information.
Confidentiality
-Ensures that data is accurate and reliable and is not modified incorrectly, whether accidentally or maliciously.
-Protection against unauthorized changes, additions, deletions, alterations.
Integrity
Protection of a system’s ability to make software systems and data fully available when a user needs it (or at a specified time).
Availability
