A hospital is migrating its patient data to a cloud provider. They want to ensure that the cloud provider has mechanisms in place to constantly monitor and report any unauthorized access or potential breaches. Which auditing and monitoring practice should they inquire about?
- Disaster Recovery Plans
- Intrusion Detection Systems (IDS)
- Penetration Testing
- Security Information and Event Management (SIEM)
To monitor and report unauthorized access or breaches, hospitals should inquire about Security Information and Event Management (SIEM) systems. SIEM solutions provide real-time analysis of security alerts and event management to ensure the early detection of potential threats.
A company wants to build a serverless application that reacts to changes in their database using Amazon DynamoDB. Which service should they consider for processing these changes?
- AWS Lambda
- Amazon EC2
- Amazon RDS
- Amazon SQS
AWS Lambda is a serverless compute service that can be triggered by changes in Amazon DynamoDB. It allows you to build applications that react to database changes without managing servers.
Which of the following can be a consequence of account hijacking?
- Data theft and loss of data control
- Improved cloud service performance
- Better user experience
- Reduced subscription costs
Account hijacking can result in data theft and loss of data control, as the attacker may manipulate or steal data. Other options are unrelated to the consequences.
In which type of virtualization is the entire desktop environment of a computer emulated on a server?
- Desktop Virtualization
- Server Virtualization
- Network Virtualization
- Application Virtualization
The correct option is 'Desktop Virtualization.' In desktop virtualization, the entire desktop environment of a computer is emulated on a server, and users access their desktops remotely. This approach allows for centralized management, security, and the ability to run different operating systems on the same hardware. Server virtualization, on the other hand, involves virtualizing server hardware to run multiple server instances on a single physical server. Network virtualization focuses on virtualizing network resources, while application virtualization virtualizes individual applications for deployment.
The concept of accessing computing resources over the internet is closely related to:
- Client-server architecture
- Cloud computing
- On-premises data centers
- Traditional telephony systems
The concept of accessing computing resources over the internet is closely related to cloud computing, as it's the essence of cloud services. It's distinct from traditional telephony, on-premises data centers, or client-server models.
A disgruntled employee with elevated access rights who intentionally sabotages the company's data is classified as which type of insider threat?
- Accidental Insider
- Competent Insider
- Malicious Insider
- Negligent Insider
A "Malicious Insider" is an employee with malicious intent who abuses their access to harm the organization intentionally. This is a severe insider threat that organizations need to protect against.
A large enterprise has a policy that mandates all software patches and updates be reviewed and tested before deployment. They are considering adopting a SaaS application. What potential challenge might they face with this approach?
- Complex Licensing Agreements
- Difficulty in Customization
- Limited Control Over Updates
- Potential Security Concerns
The challenge that a large enterprise might face with adopting a SaaS application is limited control over updates. With SaaS, the provider manages updates, which can conflict with an enterprise's patch testing and deployment policy.
For complex cloud architectures, which feature of cloud monitoring tools is crucial for understanding the interplay between different services?
- Auto Scaling
- Dependency Mapping
- Log Collection
- Performance Metrics
Dependency mapping is crucial for understanding how different services in a complex architecture rely on each other, helping diagnose issues and optimize.
What is the significance of "zero trust" in the context of preventing insider threats?
- Trust is granted by default
- Trust is granted widely
- Trust is never assumed
- Trust is revoked easily
In a "Zero Trust" security model, trust is never assumed, and verification is required from anyone trying to access resources. This approach minimizes insider threats by not assuming trust based on roles or location.
In the context of cloud computing, what does the "elasticity" characteristic ensure?
- Data Encryption
- Dynamic Scalability
- Redundancy Management
- Resource Efficiency
Elasticity in cloud computing refers to the ability to dynamically and automatically scale resources up or down in response to changing workloads. It ensures efficient resource allocation, cost savings, and performance optimization.
