SY0-701 Exam Dumps - CompTIA Security+ Questions and Answers

Jailbreaking is the process of removing the restrictions imposed by the manufacturer or carrier on a mobile device, such as an iPhone or iPad. Jailbreaking allows users to install unauthorized applications, modify system settings, and access root privileges. However, jailbreaking also exposes the device to potential security risks, such as malware, spyware, unauthorized access, data loss, and voided warranty. Therefore, an organization may prohibit employees from jailbreaking their mobile devices to prevent these vulnerabilities and protect the corporate data and network. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 10: Mobile Device Security, page 507 2

Comprehensive and Detailed Explanation From Exact Extract:

The described activity—visiting a website and downloading publicly accessible content—is a classic example of passive reconnaissance. Passive reconnaissance involves gathering information about a target without interacting with its internal systems or generating traffic that could be detected by security monitoring tools.

According to SY0-701, passive recon uses open-source intelligence (OSINT), such as:

Public websites

DNS records

News articles

Metadata

Public document repositories

The key distinction is that passive reconnaissance does not probe the system for vulnerabilities, nor does it send active scanning traffic.

Vulnerability scanning (B) requires active probing. Unknown environment testing (A) applies to black-box testing but still may involve active scanning. Due diligence (C) refers to risk assessment or compliance reviews, not technical reconnaissance.

Therefore, downloading the website’s content is a non-intrusive information-gathering technique, perfectly matching passive reconnaissance as defined in the exam materials under Threats, Vulnerabilities, Attack Vectors, and Pen Testing Phases.

SIEM stands for Security Information and Event Management. It is a security alerting and monitoring tool that collects system, application, and network logs from multiple sources in a centralized system. SIEM can analyze the collected data, correlate events, generate alerts, and provide reports and dashboards. SIEM can also integrate with other security tools and support compliance requirements. SIEM helps organizations to detect and respond to cyber threats, improve security posture, and reduce operational costs. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 10: Monitoring and Auditing, page 393.

An application allow list is a security technique that specifies which applications are authorized to run on a system and blocks all other applications. An application allow list can best protect against an employee inadvertently installing malware on a company system because it prevents the execution of any unauthorized or malicious software, such as viruses, worms, trojans, ransomware, or spyware. An application allow list can also reduce the attack surface and improve the performance of the system. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 11: Secure Application Development, page 551 1

A training curriculum plan for a security awareness program should address the following factors:

The threat vectors based on the industry in which the organization operates. This will help the employees to understand the specific risks and challenges that their organization faces, and how to protect themselves and the organization from cyberattacks. For example, a healthcareorganization may face different threat vectors than a financial organization, such as ransomware, data breaches, or medical device hacking1.

The cadence and duration of training events. This will help the employees to retain the information and skills they learn, and to keep up with the changing security landscape. The training events should be frequent enough to reinforce the key concepts and behaviors, but not too long or too short to lose the attention or interest of the employees. For example, a security awareness program may include monthly newsletters, quarterly webinars, annual workshops, or periodic quizzes2.

Tokenization replaces sensitive financial data—such as credit card numbers, account numbers, or customer identifiers—with harmless tokens that retain usability but reveal nothing if leaked. This is widely used in the financial industry, particularly in PCI-DSS-regulated systems.

Hashing (B) is one-way and not reversible, making it unsuitable for financial transactions that need original data retrieved. Salting (C) is used to protect hashed passwords, not to mask financial data. Steganography (D) hides data inside media files but is not used for payment processing.

Security+ SY0-701 identifies tokenization as the preferred method for protecting structured sensitive data while maintaining operational functionality.

Thus, the correct answer is A: Tokenization.

Detailed Explanation:

Corrective controls, such as auditing and versioning, help prevent unauthorized changes to financial data, ensuring data integrity and compliance with regulations. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: " Controls for Financial Systems " ​​.

WPA2-Enterprise is designed for environments where users authenticate with unique, individual credentials backed by an enterprise identity store, rather than a shared preshared key. The Study Guide explicitly states: “WPA2-Enterprise relies on a RADIUS authentication server as part of an 802.1X implementation for authentication. Users can thus have unique credentials and be individually identified.” That maps directly to the requirement that users verify identity against the company’s identity services using individual credentials. It further explains how this is implemented operationally: “802.1X is an IEEE standard for access control… In wireless networks, 802.1X is used to integrate with RADIUS servers, allowing enterprise users to authenticate and gain access to the network.”

Therefore, the correct configuration step is enabling 802.1X and tying authentication into the organization’s identity source (commonly a corporate directory). The other choices don’t correctly “apply RADIUS” for WPA2-Enterprise: self-signed certs are not universally required for all EAP types and can introduce trust issues; MAC filters are weak and spoofable; and MFA might be beneficial but is not the fundamental step that enables RADIUS-backed WPA2-Enterprise authentication.

The scenario describes a situation where a user unknowingly triggers an unwanted action, such as changing their password, by clicking a malicious link. This is indicative of a Cross-Site Request Forgery (CSRF) attack, where an attacker tricks the user into executing actions they did not intend to perform on a web application in which they are authenticated.

Tokenization is a process that replaces sensitive data, such as credit card information, with a non-sensitive equivalent (token) that can be used in place of the actual data. This technique is particularly useful in securely storing payment information because the token can be safely stored and transmitted without exposing the original credit card number.

The best answer is C. The common format for vulnerability scanning and reporting enables greater interoperability between security tools from different vendors.

SCAP (Security Content Automation Protocol) is a standardized framework that helps security tools use common methods for expressing, measuring, and reporting security issues such as vulnerabilities, misconfigurations, and compliance results. One of its biggest benefits is interoperability across tools from different vendors.

Because SCAP uses standardized formats and naming conventions, organizations can more easily:

share scan results

compare findings across platforms

automate vulnerability and compliance checks

integrate multiple security products

Why the other options are incorrect:

A. The configurations defined as part of established baselines allow organizations to deploy well-tested security solutions quickly and easily.Baselines are important, but this answer is too general and does not capture the main benefit of SCAP.

B. The consolidated reporting layout makes it easier for technicians to communicate incident response to senior decision-makers.SCAP is not primarily about incident response reporting to executives.

D. The strict compliance to international standards reduces overall cost and risk to organizations when a security breach occurs.This is too broad and not the clearest explanation of what SCAP actually provides.

From the SY0-701 perspective, SCAP is valuable because it supports standardized vulnerability and configuration assessment and improves tool interoperability. Therefore, C is the correct answer.

An Acceptable Use Policy (AUP) is an example of a managerial control. Managerial controls are policies and procedures that govern an organization ' s operations, ensuring security through directives and rules. The AUP defines acceptable behavior and usage of company resources, setting guidelines for employees.

Physical controls refer to security measures like locks, fences, or security guards.

Technical controls involve security mechanisms such as firewalls or encryption.

Operational controls are procedures for maintaining security, such as backup and recovery plans​​.

 An endpoint log is a file that contains information about the activities and events that occur on an end-user device, such as a laptop, desktop, tablet, or smartphone. Endpoint logs can provide valuable data for security analysts, such as the processes running on the device, the network connections established, the files accessed or modified, the user actions performed, and the applications installed or updated. Endpoint logs can also record the details of any executable files running on the device, such as the name, path, size, hash, signature, and permissions of the executable.

An application log is a file that contains information about the events that occur within a software application, such as errors, warnings, transactions, or performance metrics. Application logs can help developers and administrators troubleshoot issues, optimize performance, and monitor user behavior. However, application logs may not provide enough information about the executable files running on the device, especially if they are malicious or unknown.

An IPS/IDS log is a file that contains information about the network traffic that is monitored and analyzed by an intrusion prevention system (IPS) or an intrusion detection system (IDS). IPS/IDS logs can help security analysts identify and block potential attacks, such as exploit attempts, denial-of-service (DoS) attacks, or malicious scans. However, IPS/IDS logs may not provide enough information about the executable files running on the device, especially if they are encrypted, obfuscated, or use legitimate protocols.

A network log is a file that contains information about the network activity and communication that occurs between devices, such as IP addresses, ports, protocols, packets, or bytes. Network logs can help security analysts understand the network topology, traffic patterns, and bandwidth usage. However, network logs may not provide enough information about the executable files running on the device, especially if they are hidden, spoofed, or use proxy servers.

Therefore, the best log type to use as a data source for additional information about the executable running on the machine is the endpoint log, as it can provide the most relevant and detailed data about the executable file and its behavior.
