Implementing multi-factor authentication

Allowing unrestricted access to data

Using weak passwords

Option 1: Incorrect. Storing sensitive data in clear text is not a security best practice. It leaves the data vulnerable to unauthorized access and breaches.
Option 2: Correct. Implementing multi-factor authentication is a security best practice for securing data in the cloud. This adds an extra layer of protection by requiring users to provide additional verification beyond just a password.
Option 3: Incorrect. Allowing unrestricted access to data is not a security best practice. Access to data should be properly controlled and limited to authorized individuals or groups.
Option 4: Incorrect. Using weak passwords is not a security best practice. Strong and complex passwords should be used to prevent unauthorized access to data.

QUESTION 79
What is the purpose of an Access Control List (ACL) in cybersecurity?

To encrypt traffic between two networks

To filter network traffic based on predefined rules

To monitor network traffic for potential security threats

To authenticate users before granting them access

An Access Control List (ACL) is a list of rules that determines which network traffic is allowed and which is denied. It is used to filter network traffic based on criteria such as source/destination IP address, port numbers, and protocols. By implementing an ACL, organizations can control access to their networks, prevent unauthorized access, and enforce security policies.

QUESTION 80
Which technology is responsible for monitoring network traffic and identifying potential threats?

IDS

Firewall

Server

IPS

An Intrusion Detection System (IDS) is a technology that monitors network traffic and analyzes it for potential security breaches or vulnerabilities. It detects and alerts administrators to any suspicious activity, allowing them to take appropriate actions to mitigate potential threats.

QUESTION 81
Which of the following is an element of an incident response plan?

Installing antivirus software

Conducting regular backups

Developing security policies

Identifying vulnerabilities

An incident response plan outlines the steps and procedures to be followed when a cybersecurity incident occurs. One of the elements of an incident response plan is developing security policies. These policies serve as a framework for managing and responding to security incidents.

QUESTION 82
Which of the following helps to ensure the confidentiality of data in computer operations?

Data integrity controls

Access control lists (ACLs)

Intrusion Detection System (IDS)

Antivirus software

Access control lists (ACLs) are a security mechanism used in computer operations to enforce and manage access permissions for users and resources. ACLs enable organizations to control who can access specific data or resources, helping to ensure the confidentiality of sensitive information.

QUESTION 83
Which of the following is a common authentication protocol used in wireless networks?

FTP

WPA

SSH

SMTP

WPA (Wi-Fi Protected Access) is a widely used authentication protocol for securing wireless networks. It provides stronger security than the older WEP (Wired Equivalent Privacy) protocol by utilizing encryption algorithms and dynamic key generation. WPA offers better protection against unauthorized access and helps ensure the confidentiality and integrity of wireless communications.

QUESTION 84
Which of the following best describes the main purpose of malware removal?

To disinfect network devices from malware infections

To secure a system against potential malware attacks

To detect and remove malware that is already present on a system

To prevent malware from being installed on a system

Malware removal refers to the process of identifying and eliminating malicious software that has already infected a system. This is essential to prevent further harm and restore the system’s security.

QUESTION 85
Which of the following best defines risk management in the context of cybersecurity?

The process of analyzing potential threats and determining the likelihood and impact of those threats on an organization.

The process of ensuring the confidentiality, integrity, and availability of an organization’s information assets.
