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

Installing a host-based content filtering solution on the endpoints ensures that web traffic is filtered locally even when the VPN connection to the on-premises proxy fails, maintaining protection for remote users.

Network access control (A) manages device network access, local gateway configuration (B) does not solve protection if VPN fails, and public NAT (C) exposes internal resources and increases risk.

Endpoint filtering complements VPN for resilient web security, covered in Security Architecture and Operations【6:Chapter 11†CompTIA Security+ Study Guide】.

Access control lists (ACLs) are rules that specify which users or groups can access which resources on a file server. They can help restrict access to confidential data by granting or denying permissions based on the identity or role of the user. In this case, the administrator can use ACLs to quickly modify the access rights of the users and prevent them from accessing the data they are not authorized to see. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 308 1

A non-disclosure agreement (NDA) restricts employees from sharing proprietary or confidential information when they leave the company. Legal consequences may result from violating an NDA.

Scheduled downtime is a planned period of time when a system or service is unavailable for maintenance, updates, upgrades, or other changes. Scheduled downtime gives administrators a set period to perform changes to an operational system without disrupting the normal business operations or affecting the availability of the system or service. Scheduled downtime also allows administrators to inform the users and stakeholders about the expected duration and impact of the changes. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 12: Security Operations and Administration, page 579 1

Security of architecture is the process of designing and implementing a secure infrastructure that meets the business objectives and requirements. Security of architecture should be considered first when migrating to an off-premises solution, such as cloud computing, because it can help to identify and mitigate the potential risks and challenges associated with the migration, such as data security, compliance, availability, scalability, and performance. Security of architecture is different from security of cloud providers, which is the process of evaluating and selecting a trustworthy and reliable cloud service provider that can meet the security and operational needs of the business. Security of architecture is also different from cost of implementation, which is the amount of money required to migrate and maintain the infrastructure in the cloud. Security of architecture is also different from ability of engineers, which is the level of skill and knowledge of the IT staff who are responsible for the migration and management of the cloud infrastructure. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 3491

A high-availability network is a network that is designed to minimize downtime and ensure continuous operation of critical services and applications. To achieve this goal, a high-availability network must consider two important factors: ease of recovery and attack surface.

Ease of recovery refers to the ability of a network to quickly restore normal functionality after a failure, disruption, or disaster. A high-availability network should have mechanisms such as redundancy, failover, backup, and restore to ensure that any single point of failure does not cause a complete network outage. A high-availability network should also have procedures and policies for incident response, disaster recovery, and business continuity to minimize the impact of any network issue on the organization’s operations and reputation.

Attack surface refers to the exposure of a network to potential threats and vulnerabilities. A high-availability network should have measures such as encryption, authentication, authorization,firewall, intrusion detection and prevention, and patch management to protect the network from unauthorized access, data breaches, malware, denial-of-service attacks, and other cyberattacks. A high-availability network should also have processes and tools for risk assessment, threat intelligence, vulnerability scanning, and penetration testing to identify and mitigate any weaknesses or gaps in the network security.

Improving security awareness training directly addresses user behavior by teaching employees how to better recognize legitimate emails versus actual phishing attempts. Enhanced training can reduce the number of false positives by helping users more accurately identify true phishing attempts, lowering unnecessary reports and thus help desk workload.

A Host-based Intrusion Prevention System (HIPS) provides both preventive and detective security controls. Security+ SY0-701 describes HIPS as a host-level security solution that monitors system behavior, blocks malicious activity, and logs suspicious events.

It functions as a preventive control (B) because it can:

Stop malware execution

Block unauthorized changes

Prevent exploit attempts

Enforce endpoint protection policies

It is also a detective control (F) because it can:

Record attempted attacks

Identify suspicious activities

Generate alerts for security teams

Directive controls (A) refer to policies; physical controls (C) refer to locks and barriers; corrective controls (D) restore systems after an incident; compensating controls (E) substitute for missing primary controls.

Therefore, the two correct answers are B (Preventive) and F (Detective).

Typosquatting is a social engineering and cybersquatting technique in which attackers register domain names similar to legitimate ones, hoping users will make a typographical error and visit their malicious website instead.

 A firewall rule is a set of criteria that determines whether to allow or deny a packet to pass through the firewall. A firewall rule consists of several elements, such as the action, the protocol, the source address, the destination address, and the port number. The syntax of a firewall rule may vary depending on the type and vendor of the firewall, but the basic logic is the same. In this question, the security analyst is creating an inbound firewall rule to block the IP address 10.1.4.9 from accessing the organization’s network. This means that the action should be deny, the protocol should be any (or ig for IP), the source address should be 10.1.4.9/32 (which means a single IP address), the destination address should be 0.0.0.0/0 (which means any IP address), and the port number should be any. Therefore, the correct firewall rule is:

access-list inbound deny ig source 10.1.4.9/32 destination 0.0.0.0/0

This rule will match any packet that has the source IP address of 10.1.4.9 and drop it. The other options are incorrect because they either have the wrong action, the wrong source address, or the wrong destination address. For example, option A has the source and destination addresses reversed, which means that it will block any packet that has the destination IP address of 10.1.4.9, which is not the intended goal. Option C has the wrong action, which is permit, which means that it will allow the packet to pass through the firewall, which is also not the intended goal. Option D has the same problem as option A, with the source and destination addresses reversed.

Theprimary goal of corrective controls in financial systems is to ensure that errors do not propagate across interconnected systems. Financial transactions are ofteninterdependent, meaning one incorrect or unauthorized change can affect multiple systems. Regulations often mandate these controls tomaintain accuracy and prevent cascading failures.

A (insider threats altering banking details)is a concern, but thisscenario focuses on corrective controls, not insider threats specifically.

C (business insurance)is unrelated to why corrective controls are implemented.

D (preventing unauthorized changes)falls underpreventive, notcorrectivecontrols.

Purple is the team that combines both offensive and defensive testing techniques to protect an organization’s critical systems. Purple is not a separate team, but rather a collaboration between the red team and the blue team. The red team is the offensive team that simulates attacks and exploits vulnerabilities in the organization’s systems. The blue team is the defensive team that monitors and protects the organization’s systems from real and simulated threats. The purple team exists to ensure and maximize the effectiveness of the red and blue teams by integrating the defensive tactics and controls from the blue team with the threats and vulnerabilities found by the red team into a single narrative that improves the overall security posture of the organization. Red, blue, and yellow are other types of teams involved in security testing, but they do not combine both offensive and defensive techniques. The yellow team is the team that builds software solutions, scripts, and other programs that the blue team uses in the security testing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 1331; Penetration Testing: Understanding Red, Blue, & Purple Teams3

The security engineer is likely to deploy a Web Application Firewall (WAF) to protect the new web portal service. A WAF specifically protects web applications by filtering, monitoring, and blocking HTTP requests based on a set of rules. This is crucial for preventing common attacks such as SQL injection, cross-site scripting (XSS), and other web-based attacks that could compromise the web service.

Layer 4 firewall operates primarily at the transport layer, focusing on IP address and port filtering, making it unsuitable for web application-specific threats.

NGFW (Next-Generation Firewall) provides more advanced filtering than traditional firewalls, including layer 7 inspection, but the WAF is tailored specifically for web traffic.

UTM (Unified Threat Management) offers a suite of security tools in one package (like antivirus, firewall, and content filtering), but for web application-specific protection, a WAF is the best fit​​​.
