B1 Flashcards
What type of system is archival?
Passive system
What is definition?
First step of data life cycle where an organization identifies what data is needed and where to store it.
What is synthesis?
The step between preparation and usage, when data is prepared for quicker usage and analysis.
What is purging
Final stage where data is deleted/removed.
What is a proxy log?
Tracks users visits, the time of visit, and how long each page was viewed.
What is acceptance criteria?
Qualitative and quantitative information used to determine whether new applications are satisfactory and meet end user expectations.
What is system component inventory?
Changes in inventory that track changes in trends in asset acquisition and development.
What is a multi-tenant cloud service provider?
More than one organization using shared virtual infrastructure.
What is a differential backup?
Includes all changes copied since the last full backup.
What is Maximum tolerable downtime, Recovery point objective, recovery point actual, recovery time objective.
MTD is the amount of TIME a company can be down before its profits are affected.
RPO is a metric OTHER than time used to define an intolerable loss of data.
RPA the amount of time it took to get the system running again.
RTO The maximum amount of TIME it should take to restore operations has nothing to do with a decrease in profits.
What is the relationship between an enterprise planning ERP and an accounting information system AIS
AIS is a subsystem of ERP.
What is vertical scalability?
The ability to add more storage and computing power to a cloud.
What is close-loop verification?
When one party verifies the identity of another.
Identify what each SQL is used for FROM, SELECT, GROUP BY, and WHERE
FROM: Specifies from which table or tables that should be retrieved.
SELECT: Indicated what attributes to view.
GROUP BY: Used to aggregate data into subtotals
WHERE: Used to filter records in the database based on specific criteria for example numbers greater than 5
What is the difference between Incremental and differential backups?
Incremental copies only data that has changes since the last backup while differential copies all changes/ activities since the last backup.
What are the four implementation tiers in the NIST CSF?
Tier 1(Risk Informed): Incidents are not integrated into organizational processes. (worst)
Tier 2(Partial): Involved in cybersecurity awareness but not securely managed. (Second Worst)
Tier 3(Repeatable): Cybersecurity risk is integrated into planning and regularly communicated among leadership (Second best)
Tier 4(Adaptive): Prioritizes management of cyber risks (Strongest)
What is a pilot conversion?
When an organization test a new system on a small scale in a non-production environment and if it is successful then it is implemented into the rest of the organization.
What is a phase approach?
When a system is gradually implemented (NOT first implemented in a small scale)
Explain the steps of extract, transform, and load ETL.
E when data is gathered and retrieved from its sources
T when data is converted and transferred into useful information
L When prepared cleaned data is ready for use
Which step in ETL allows for active data collection or passive data collection.
Capture which is the first step.
What is shared services?
When an organization has three different sectors, but it decides to combine all three.
What is logistic regression?
Statistical model that predicts outcomes.
Neural Network,
Works like a brain it has input layer, hidden layer, and an output layer.
