During a security audit, it's discovered that an unauthorized device is connected to the company's Wi-Fi network. This could be due to a ____________ security lapse.
- Authentication
- Configuration
- Encryption
- Physical Security
The discovery of an unauthorized device on a Wi-Fi network often points to a configuration security lapse. Inadequate configuration settings may allow unauthorized access, emphasizing the importance of configuring network devices securely. Implementing strong configuration practices is essential to prevent unauthorized devices from connecting to the network, enhancing overall security.__________________________________________________
Which term describes the likelihood of a threat exploiting a vulnerability?
- Exploitation
- Risk
- Threat
- Vulnerability
The term that describes the likelihood of a threat exploiting a vulnerability is "exploitation." Risk is the combination of the threat, vulnerability, and potential impact. A threat is a potential danger, a vulnerability is a weakness, and exploitation is the actual act of taking advantage of that weakness. Understanding these terms is fundamental in assessing and managing cybersecurity risks effectively.__________________________________________________
____________ involves analyzing the physical memory of a computer to recover evidence and investigate cyber crimes.
- Disk Imaging
- Incident Response
- Memory Forensics
- Network Forensics
Memory forensics is the process of analyzing the physical memory (RAM) of a computer system to recover evidence related to cyber crimes. It allows investigators to identify running processes, open network connections, and uncover artifacts that may not be stored on disk. Proficiency in memory forensics is vital for investigating volatile data and understanding the state of a system during an incident.__________________________________________________
How does AI enhance the effectiveness of intrusion detection systems?
- Analyzing large datasets for unusual behavior
- Backing up data regularly
- Creating stronger passwords
- Physical access control measures
AI enhances the effectiveness of intrusion detection systems by analyzing large datasets for unusual behavior. Machine learning algorithms can identify patterns indicative of intrusions, adapting over time to evolving threats. This capability significantly improves the system's ability to detect sophisticated attacks, making AI an invaluable tool for strengthening cybersecurity defenses. Recognizing the role of AI in intrusion detection is essential for organizations seeking advanced threat detection capabilities.__________________________________________________
Which VPN protocol is known for providing strong encryption and high security?
- L2TP
- OpenVPN
- PPTP
- SSTP
OpenVPN is widely recognized for providing strong encryption and high-security levels in VPN communication. It utilizes open-source technology and supports various encryption algorithms, making it a preferred choice for secure data transmission. Recognizing the strengths of different VPN protocols is essential for selecting the most suitable one based on security requirements and compatibility.__________________________________________________
In a security policy, ____________ refers to the continuous process of monitoring and assessing risks.
- Risk Evaluation
- Security Auditing
- Threat Analysis
- Vulnerability Assessment
Risk evaluation is the ongoing process of monitoring and assessing risks in a security policy. It involves identifying potential threats, analyzing vulnerabilities, and determining the likelihood and impact of various security incidents. A robust risk evaluation helps organizations prioritize and implement security measures to mitigate potential risks effectively.__________________________________________________
In cryptography, what is the difference between symmetric and asymmetric encryption?
- Asymmetric is less secure than symmetric
- Both use the same key for encryption and decryption
- Symmetric is slower than asymmetric
- Symmetric uses one key; asymmetric uses a pair of keys
Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption employs a pair of keys (public and private). The use of a key pair enhances security but can be computationally more intensive. Understanding the distinctions between these encryption methods is crucial for implementing appropriate security measures in various scenarios.__________________________________________________
What is the purpose of using MAC address filtering in a wireless network?
- Encrypting data transmission
- Filtering website content
- Monitoring network traffic
- Restricting access based on device hardware
MAC address filtering is used to restrict access to a wireless network based on the unique hardware address of each device. By allowing or denying connections based on MAC addresses, network administrators can enhance security by only permitting authorized devices. This additional layer of access control helps prevent unauthorized devices from connecting to the network, reinforcing overall wireless network security.__________________________________________________
What is the significance of a 'zero-day exploit' in the context of ethical hacking?
- A hacking technique with zero risks
- An exploit designed for zero impact on systems
- An exploit for vulnerabilities known for zero days
- An exploit targeting a previously unknown vulnerability
A 'zero-day exploit' targets a vulnerability unknown to the software vendor and security community. Ethical hackers may use such exploits to assess system vulnerabilities before malicious actors discover and exploit them. Understanding the implications of zero-day exploits is crucial for ethical hacking professionals to proactively address security weaknesses and protect systems from potential threats.__________________________________________________
Which of the following is a common type of malware that replicates itself to spread to other computers?
- Ransomware
- Spyware
- Trojan Horse
- Worm
A worm is a type of malware that can replicate itself and spread to other computers without human intervention. It can exploit vulnerabilities in computer systems to propagate.__________________________________________________
