Cloud computing and security challenges MCQs

Cloud computing refers to the delivery of computing services, including storage, processing power, and applications, over the internet.

Public cloud services offer cost-effective scalability, allowing users to pay for resources based on their actual usage.

Infrastructure as a Service (IaaS) provides virtualized computing resources, such as virtual machines, over the internet.

The responsibility model in cloud computing defines the division of security responsibilities between the cloud provider and the customer.

Data segregation is a common security concern in multi-tenancy, where multiple users share the same resources in a cloud environment.

AES (Advanced Encryption Standard) is commonly used to encrypt data in transit in cloud computing.

A Man-in-the-Middle (MitM) attack involves an attacker intercepting and altering communication between two parties.

Private cloud deployment allows organizations to have the highest level of control over their infrastructure.

CASB enforces security policies in cloud services and ensures secure access to cloud resources.

The shared responsibility model in cloud computing can lead to unclear security responsibilities between the cloud provider and the customer.

Encryption is the practice of securing data by converting it into a code that is unreadable without the correct decryption key.

A Virtual Private Network (VPN) in cloud security provides network isolation to secure communication over the internet.

SQL injection is a security attack where an attacker injects malicious SQL code to exploit vulnerabilities in a cloud service.

SIEM systems in cloud security are used for monitoring and analyzing security events to detect and respond to security incidents.

Multi-Factor Authentication (MFA) involves using a combination of something the user knows (password) and something the user possesses (token, smartphone, etc.).

Tokenization in cloud security involves replacing sensitive data with a token to protect the original data.

Data redundancy is a cloud security model where data is stored in multiple locations to ensure availability and resilience.

Hybrid cloud deployment involves using a combination of private and public clouds to host an organization's applications.

Role-based access control (RBAC) restricts user access based on their roles, ensuring they only have access to necessary information and resources.

The primary goal of a DDoS attack in the context of cloud security is to disrupt service availability by overwhelming the targeted system with a flood of traffic.

Platform as a Service (PaaS) provides a platform that allows customers to develop, run, and manage applications without dealing with the underlying infrastructure.

Hashing is the process of securing data by applying a mathematical function to generate a fixed-size string of characters.

Cloud Security Posture Management (CSPM) is used for assessing and maintaining security configurations in the cloud.

A phishing attack involves an attacker tricking a user into revealing sensitive information by pretending to be a trustworthy entity.

Software as a Service (SaaS) provides end-users with access to software applications over the internet without the need for installation on their devices.

Cloud Security Access Brokers (CSAB) enforce security policies in cloud services and ensure secure access to cloud resources.

Cross-Site Scripting (XSS) is a security attack where an attacker injects malicious scripts into web pages viewed by other users.

A Web Application Firewall (WAF) in cloud security is used to enforce security policies for web applications and protect against various web-based attacks.

Network segmentation is a security measure that separates a network into segments to prevent unauthorized access to sensitive data.

Community cloud deployment involves providing cloud services to a specific group of organizations with shared interests or requirements.

Elasticity in cloud computing allows resources to be allocated dynamically based on demand, ensuring efficient resource utilization.

Infrastructure as a Service (IaaS) provides on-demand access to computing resources without the need for physical hardware.

Microsegmentation is a security measure that monitors and controls network traffic between virtual machines within a cloud environment.

Community cloud deployment involves sharing cloud resources among multiple organizations with similar security and compliance requirements.

A Cloud Service Level Agreement (SLA) defines the terms and conditions of service between a cloud provider and a customer.

Identity and Access Management (IAM) involves authenticating and authorizing users and devices to access cloud resources.

Data Loss Prevention (DLP) in cloud security involves monitoring and preventing the unauthorized transmission of sensitive data.

Data encryption in cloud security involves encrypting data stored in the cloud to protect it from unauthorized access.

Cloud Security Alliance (CSA) provides a set of controls and best practices for securing information in the cloud.

CASB enforces security policies in cloud services and ensures secure access to cloud resources.

Data redundancy involves creating backups of data to prevent data loss in the event of a security incident or system failure.

Cloud Security Information and Event Management (SIEM) systems are used for monitoring and analyzing security events in the cloud.

Hybrid cloud deployment involves using both on-premise infrastructure and cloud services to host an organization's applications.

CSPM is used for assessing and maintaining security configurations in the cloud.

A Distributed Denial of Service (DDoS) attack involves flooding a network or system with traffic to disrupt its normal functioning.

Function as a Service (FaaS) provides a runtime environment for executing code in response to events without the need for server management.

Role-based access control (RBAC) involves monitoring and controlling user access to cloud resources based on predefined policies.

CSAB enforces security policies in cloud services and ensures secure access to cloud resources.

SIEM is a security measure that involves monitoring and analyzing user activities in the cloud to detect and respond to suspicious behavior.

CSPM is used for assessing and maintaining security configurations in the cloud.
