A ____________ attack occurs when multiple compromised systems are used to target a single system causing denial of service.
- Cross-Site Scripting (XSS)
- DDoS (Distributed Denial of Service)
- SQL Injection
- Zero-Day Exploit
A Distributed Denial of Service (DDoS) attack occurs when multiple compromised systems are used to target a single system, overwhelming it with traffic and causing a denial of service. Recognizing and mitigating DDoS attacks is crucial for maintaining the availability and reliability of online services and preventing disruptions to users.__________________________________________________
The process of recovering deleted, encrypted, or damaged file information is known as ____________.
- Data Recovery
- Data Salvage
- Digital Reconstruction
- File Restoration
Data recovery is the process of retrieving deleted, encrypted, or damaged file information. It involves restoring data from storage media when it becomes inaccessible. This aspect of cybersecurity is crucial for minimizing data loss and ensuring that organizations can recover critical information in case of accidental deletion or other incidents.__________________________________________________
What is the purpose of a 'consensus algorithm' in a blockchain network?
- Encrypt data transmission
- Prevent distributed denial-of-service (DDoS) attacks
- Reach agreement on the state of the blockchain
- Secure user authentication
A 'consensus algorithm' in a blockchain network is designed to achieve agreement among nodes on the state of the blockchain. It ensures that all participants validate and agree on the same set of transactions, maintaining the integrity and immutability of the distributed ledger. Understanding consensus algorithms is fundamental for evaluating the security and efficiency of a blockchain network.__________________________________________________
What is two-factor authentication (2FA) in cybersecurity?
- A method of verifying identity using two factors
- A password manager
- Multi-factor authentication
- Single-factor authentication
Two-factor authentication involves using two independent factors to verify identity. This typically includes something you know (like a password) and something you have (like a mobile device). Unlike single-factor authentication, which relies on just one factor, 2FA provides an additional layer of security, making it harder for unauthorized individuals to gain access. Understanding this is crucial for implementing robust authentication mechanisms.__________________________________________________
The integration of ____________ into 5G networks aids in the early detection and response to cyber threats.
- Artificial Intelligence (AI)
- Blockchain
- Internet of Things (IoT)
- Machine Learning (ML)
The integration of Artificial Intelligence (AI) into 5G networks enhances cybersecurity by enabling early detection and response to cyber threats. AI algorithms can analyze network patterns in real-time, identifying anomalies and potential security breaches. Understanding the role of AI in 5G is crucial for implementing proactive cybersecurity measures in the evolving landscape of telecommunications.__________________________________________________
What does the term 'phishing' primarily refer to in cyber security?
- A hardware device for network monitoring
- A method of securing computer networks
- A type of encryption technique
- An attempt to deceive individuals to reveal sensitive information
Phishing is a cyber attack where attackers impersonate trusted entities to trick individuals into revealing sensitive information such as passwords and credit card numbers.__________________________________________________
A company's AI-driven security system automatically isolated a segment of its network upon detecting unusual activity, illustrating ____________ response.
- Automated Incident Response
- Forensic Analysis
- Security Information and Event Management (SIEM)
- Threat Hunting
The automatic isolation of a network segment by an AI-driven security system in response to unusual activity reflects an automated incident response. Automated incident response leverages AI and machine learning to autonomously detect, analyze, and mitigate security incidents. Understanding this capability is essential for organizations seeking efficient and timely responses to security events, reducing manual intervention and enhancing overall incident response effectiveness.__________________________________________________
How does Machine Learning (ML) differ from traditional cybersecurity methods in detecting new threats?
- ML is more time-consuming than traditional methods
- ML relies on patterns and self-learning to adapt to new threats
- Traditional methods focus on manual analysis
- Traditional methods use signature-based detection
Machine Learning (ML) excels in detecting new threats by analyzing patterns and adapting over time. Unlike traditional methods that rely on predefined signatures, ML leverages self-learning algorithms to identify emerging threats based on behavior and patterns. Understanding this distinction is crucial for implementing effective threat detection mechanisms in cybersecurity.__________________________________________________
A company's IoT devices are compromised through an unsecured API endpoint. This incident emphasizes the importance of ____________ in IoT security.
- API Security
- Device Authentication
- Encryption
- Network Segmentation
The compromise through an unsecured API endpoint underscores the critical role of API security in IoT. Securing APIs is essential to prevent unauthorized access and data breaches. Implementing strong authentication, securing endpoints, and encrypting data transmitted via APIs are crucial aspects of comprehensive API security strategies, mitigating risks associated with IoT device vulnerabilities.__________________________________________________
During a penetration test, a tester successfully bypasses the authentication process of an application. This is an example of ____________.
- Authentication Bypass
- Credential Spoofing
- Denial of Service (DoS)
- Privilege Escalation
An authentication bypass occurs when a tester or attacker successfully circumvents the authentication process to gain unauthorized access. Recognizing this scenario is essential for evaluating the security posture of applications. It highlights the need for robust authentication mechanisms to prevent unauthorized access and protect sensitive data from malicious actors.__________________________________________________
What does REST stand for in the context of API design?
- Remote Server Transfer
- Representational State Transfer
- Resource State Translation
- Responsive Security Technique
REST stands for Representational State Transfer. It is an architectural style for designing networked applications. RESTful APIs use standard HTTP methods and follow a stateless client-server communication model. Understanding REST principles is crucial for designing scalable and interoperable APIs. It emphasizes simplicity, scalability, and a uniform interface for better communication between different systems in the context of web services and APIs.__________________________________________________
A hospital's electronic patient health records system is audited. The audit's focus on ensuring HIPAA compliance primarily involves assessing ____________.
- Access Controls
- Data Encryption
- Employee Training
- Incident Response Plan
HIPAA compliance in a hospital's electronic patient health records system audit involves a focus on access controls. Access controls ensure that only authorized individuals have access to patient health information, reducing the risk of unauthorized disclosure. Understanding and implementing robust access controls are essential for safeguarding patient data and meeting HIPAA requirements in healthcare environments.__________________________________________________
