Study Notes
Access Control Lists
- A Discretionary Access Control List (DACL) in Active Directory determines access rights to a specific resource or object.
- A System Access Control List (SACL) in Windows operating systems controls auditing and logging of access to a resource or object.
Data Security
- Data security refers to the protection of digital data from unauthorized access, use, disclosure, disruption, modification, or destruction.
- Key practices included in data security are:
- Confidentiality: protecting data from unauthorized access
- Integrity: ensuring data accuracy and completeness
- Availability: ensuring data is accessible when needed
Discretionary Access Control (DAC)
- DAC mechanism controls discretionary access control, which allows the owner of a resource to specify which users or groups have access to it.
Payment Security
- The solution for payments security provides a secure way to process online transactions, protecting sensitive customer information.
File Attributes
- File attributes in a computer system are properties or characteristics of a file, such as read-only, archive, or hidden, which affect how the file is handled or accessed.
- The purpose of file attributes is to provide additional functionality or control over file access and management.
Data Erasure
- Data erasure achieves complete removal of data from a storage device, ensuring it cannot be recovered or accessed.
File Masking
- File masking allows organizations to replace sensitive data with fictional, but realistic, data, ensuring data privacy while maintaining data utility.
Volume Label
- The purpose of a volume label in a computer system is to provide a human-readable name for a storage volume or device.
Data Resiliency
- Data resiliency determines an organization's ability to maintain business operations and data accessibility despite disruptions or outages.
Encryption
- The function of encryption in data security is to protect data by converting it into an unreadable format, ensuring it remains confidential and secure.
File Attributes (Read-Only, Archive, Hidden)
- The 'read-only' attribute for a file in a computer system prevents modifications or deletions.
- The 'archive' attribute plays a role in file backup and restoration, as it marks files that have changed since the last backup.
- The primary function of the 'hidden' attribute for a file in DOS is to hide files from the default directory listing, protecting sensitive files from casual access.
