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.
