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.__________________________________________________
