Information Systems Part 1 Flashcards
How can machine learning improve the performance of Accounting Information Systems?
- By AUTOMATING repetitive and manual tasks
- Ex: QuickBooks and the Bank Feed
Why do organizations use Accounting Information Systems?
- To store, collect, and process financial data
- The AIS generates important reports that are part of decision making for managers and stakeholders.
When an Accounting Information System is a module in an Enterprise Resource Planning system, what bad thing happens?
- The AIS relies on a single database that is accessible by every individual within the company
- Because of this, an improper segregation of duties can occur
What is an Enterprise Resource Planning system?
- It is a business information system that automates business processes, share common data, and facilitate reporting in real-time, which improves flexibility and responsiveness
- Example: Microsoft Dynamics 365
- It integrates data from different functional areas, customers, and vendors
What are common IT system changes?
- Upgrades
- Cloud transitions
- Additions/Deletions
- Configuration changes
- Code modifications
- Updates/Patches
- Data modifications
How should policies and procedures for requesting, approving, implementing, and monitoring changes to IT resources be documented?
They should be documented in a written CHANGE MANAGEMENT PLAN that is repeatable and auditable
Vendors and customers share responsibility for ____ of a SaaS cloud application?
SECURITY
- The customer manages their own settings and physical security at their location.
- The vendor manages the physical security and overall controls.
What is IT architecture?
It is a FUNCTIONAL RISK AREA that focuses on an organization’s ability to develop systems that align corporate strategy, organizational objectives, and long-term technologies (hardware, software, data, procedures)
What is public cloud?
- 3rd party service provider owns IT computing architecture
- Multiple public users can share access to public cloud resources
- This results in lower costs, scalability (ability to be changed in size/scale)
What is hybrid cloud?
It uses a combo of public, private, and community cloud models
What is a community cloud?
- It is a cloud that can be used by a specific group of organizations with a common purpose
- Ex: Hospital chain uses this cloud to share patient info
What is CONTINUOUS INTEGRATION?
It is a change development practice where code changes are frequently and automatically integrated into a shared repository with the objective of catching bugs early in the development process
What is automated testing?
It is the most common method of validating Continuous Integration Code changes before deployment
What is the order of continuous integration?
- Unit
- Integration
- System
- Acceptance
What are availability reports?
- They are reports that directly address system uptime and downtime durations.
- These reports measure compliance with service level agreements.
What is a Service Level Agreement?
- Many organizations use these to define the details regarding the provision of an IT service (ex: networking services) from a 3rd party vendor.
- Service level agreements are important because they specify expectations of service availability, usage, performance, capacity, processing, storage requirements, responsibilities of each party, and penalties
What is the correct sequence of activities in a patch management process?
1) Identification/creation
2) Scheduling
3) Testing
4) Deployment
5) Audit/Assessment
What is patch management?
It is the process of identifying, testing, and applying software updates (patches) to fix vulnerabilities, enhance performance, and ensure the security of systems
What is patch management important for?
It is important for hosting machines with operating systems because by regularly applying updates (patches) to the OS, the OS can get protection against security vulnerabilities.
What are the COSO internal control components?
Control Environment
Risk Assessment
Information and Communication
Monitoring
Control Activities
What does the control environment of COSO internal control - integrated framework encompass?
Tone at the top
Organizational structure
Ethical values
Why are walkthroughs performed?
To obtain a qualitative understanding of a process
What does testing the operating effectiveness of controls involve?
It involves QUANTITATIVE testing on a sample or general population
What is a differential backup?
- It stores all the data since the last full backup
- Requires less storage than full backups
- Restoration time is long
- It requires more storage than incremental backups
What is an incremental backup?
It stores data that is generated or changed since the last full or incremental backup
What are the duties of a Cloud Computing Steering Committee?
They decide what processes, applications, or data should move to the cloud
What is the Mean Time to Recover?
This tracks the average time it takes to restore a service or system after an outage
What is a key purpose of the ANALYSIS phase of a business impact ANALYSIS?
To identify, score, and prioritize critical business functions
What are the 5 phases of a business impact analysis?
- Prepare
- Gather information
- Analyze
- Write/Present BIA report
- Implement
What is the business impact analysis?
It is a process for evaluating the consequences of a disruption to critical business functions
What is a gantt chart?
It is a visual representation of project management timelines that are used for planning
What are tabletop exercises?
- This is 1 method of testing existing Business Continuity Plans
- All personnel with BCP duties meet and walk through a potential disruption scenario to find and mitigate deficiencies
What is the difference between phased and parallel installation processes?
A parallel approach involves running 2 systems simultaneously, but some users are on the new system while others are on the old system under the phased approach
What is the phased approach?
It allows a company with multiple geographic locations to gradually implement new systems one location at a time, minimizing operation disruptions
What is MIRRORING?
- It involves keeping at least 2 identical copies of a database on separate machines
- Only 1 copy (principal database) is available for use
- Updates to the principal database are copied to the mirrored database.
What is REPLICATION?
It is multiple copies of data and database objects on different databases
What is a distributed database?
- It is a database that can be replicated but not mirrored
- Replication of distributed systems allows applications to access remote databases in multiple locations
- Since distributed data is stored in multiple databases, rather than a centralized database, it would be impossible to create a single mirror of the entire database
What are data interface controls?
- They are communication rules that may use middleware software configured with controls, which ensure prompt data transfers
- These controls address access, session lengths, protocols, and security
