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

Packet capture data can be very large and may not need to be stored for extended periods compared to other logs essential for security audits.

=================

The act described is espionage, where classified information is stolen and provided to adversaries or unauthorized parties, usually for political, military, or strategic advantage.

Data exfiltration (B) is the technical act of stealing data but doesn’t specify motivation. Financial gain (C) or blackmail (D) could be motivations but are not clearly indicated here.

Espionage is a classic threat actor motivation outlined in the Threats domain【6:Chapter 2†CompTIA Security+ Study Guide】.

Social engineering is the practice of manipulating people into performing actions or divulging confidential information, often by impersonating someone else or creating a sense of urgency or trust. The suspicious caller in this scenario was trying to use social engineering to trick the user into giving away credit card information by pretending to be the CFO and asking for a payment. The user recognized this as a potential scam and reported it to the IT help desk. The other topics are not relevant to this situation. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 19 1

When conducting a forensic analysis after an incident, it ' s essential to prioritize the data collection process based on the " order of volatility. " This principle dictates that more volatile data (e.g., data in memory, network connections) should be captured before less volatile data (e.g., disk drives, logs). The idea is to preserve the most transient and potentially valuable evidence first, as it is more likely to be lost or altered quickly.

Aprocedureprovides step-by-step instructions on how to complete a specific security task, ensuring consistency and accuracy. Unlike policies, which define high-level security expectations,procedures are detailed and operational. For example, apassword reset procedurewould outline the exact steps IT support must follow when assisting users.

Policy: Defines security objectives and rules (e.g., " All passwords must be complex " ).

Standard: Specifies required technologies or configurations.

Guideline: Provides recommendations but is not mandatory.

Procedure: Gives exact instructions to perform tasks.

Detailed Explanation:

Sanctions imposed for non-compliance can include fines, legal actions, and loss of business licenses. These pose a significant financial and reputational risk to organizations.

Phishing is a type of social engineering attack that involves sending fraudulent emails that appear to be from legitimate sources, such as payment websites, banks, or other trusted entities. The goal of phishing is to trick the recipients into clicking on malicious links, opening malicious attachments, or providing sensitive information, such as log-in credentials, personal data, or financial details. In this scenario, the employee received an email from a payment website that asked the employee to update contact information. The email contained a link that directed the employee to a fake website that mimicked the appearance of the real one. The employee entered the log-in information, but received a “page not found” error message. This indicates that the employee fell victim to a phishing attack, and the attacker may have captured the employee’s credentials for the payment website. References = Other Social Engineering Attacks – CompTIA Security+ SY0-701 – 2.2, CompTIA Security+: Social Engineering Techniques & Other Attack … - NICCS, [CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition]

Vulnerability 1 should be patched first because it has both the highest severity and the highest exposure. A CVSS score of 9.8 indicates a critical vulnerability, and the affected server is internet-facing. Internet-facing systems are directly exposed to external threat actors, automated scanning, exploit kits, and opportunistic attacks. Vulnerability 4 also has a CVSS score of 9.8, but it is internal, so the exposure is lower unless an attacker already has access inside the environment. Vulnerabilities 2 and 3 have lower CVSS scores and therefore lower technical severity. Security+ prioritization considers severity, asset exposure, exploitability, and business impact. The critical internet-facing vulnerability is the most urgent.

Changing the default password for the local administrator account on a VPN appliance is a basic security measure that would have most likely prevented the unexpected login to the remote management interface. Default passwords are often easy to guess or publicly available, and attackers can use them to gain unauthorized access to devices and systems. Changing the default password to a strong and unique one reduces the risk of brute-force attacks and credential theft. Using least privilege, assigning individual user IDs, and reviewing logs more frequently are also good security practices, but they are not as effective as changing the default password in preventing the unexpected login. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 116; Local Admin Accounts - Security Risks and Best Practices (Part 1)

Firewall logs are the best source for identifying the attacker’s source IP address during port scanning activity at the network edge. A firewall sits at or near the boundary between trusted and untrusted networks and records traffic attempts, including source IP, destination IP, protocol, port, action taken, and timestamps. Since the scans are occurring on the edge of the corporate network, firewall telemetry is the most relevant data source. Security logs usually refer to operating system authentication or authorization events, not perimeter scan traffic. Application logs record application-level behavior and errors. Endpoint logs are useful for host activity, processes, and local connections, but the question specifically points to edge scanning. Therefore, firewall logs are the correct operational source.

Detailed Explanation:Avoidance involves choosing not to engage in activities or markets where certain risks are present. This is a proactive approach to risk management. Reference: CompTIA Security+ SY0-701 Study Guide, Domain 5: Security Program Management, Section: " Risk Management Strategies " ​​.

Brute force is a type of attack that tries to guess the password or other credentials of a user account by using a large number of possible combinations. An attacker can use automated tools or scripts to perform a brute force attack and gain unauthorized access to the account. The domain activity logs show that the user ismith has failed to log in 10 times in a row within a short period of time, which is a strong indicator of a brute force attack. The logs also show that the source IP address of the failed logins is different from the usual IP address of ismith, which suggests that the attacker is using a different device or location to launch the attack. The security analyst should take immediate action to block the attacker’s IP address, reset ismith’s password, and notify ismith of the incident. References = CompTIA Security+ Study Guide with over 500 Practice Test Questions: Exam SY0-701, 9th Edition, Chapter 1, page 14.

Tuning is the activity of adjusting the configuration or parameters of a security tool or system to optimize its performance and reduce false positives or false negatives. Tuning can help to filter out the normal or benign activity that is detected by the security tool or system, and focus on the malicious or anomalous activity that requires further investigation or response. Tuning can also help to improve the efficiency and effectiveness of the security operations center by reducing the workload and alert fatigue of the analysts. Tuning is different from aggregating, which is the activity of collecting and combining data from multiple sources or sensors to provide a comprehensive view of the security posture. Tuning is also different from quarantining, which is the activity of isolating a potentially infected or compromised device or system from the rest of the network to prevent further damage or spread. Tuning is also different from archiving, which is the activity of storing and preserving historical data or records for future reference or compliance. The act of ignoring detected activity in the future that is deemed normal by the security operations center is an example of tuning, as it involves modifying the settings or rules of the security tool or system to exclude the activity from the detection scope. Therefore, this is the best answer among the given options. References = Security Alerting and Monitoring Concepts and Tools – CompTIA Security+ SY0-701: 4.3, video at 7:00; CompTIA Security+ SY0-701 Certification Study Guide, page 191.

The first step in creating an anomaly detection process is building a baseline of normal behavior within the system. This baseline serves as a reference point to identify deviations or anomalies that could indicate a security incident. By understanding what normal activity looks like, security teams can more effectively detect and respond to suspicious behavior.

Multifactor authentication (MFA) requires users to provide two or more of the following categories:

Something you know (password/PIN)

Something you have (token/smart card)

Something you are (biometrics)

Authentication tokens (A) qualify as something you have, such as hardware tokens, OTP apps, or smart cards.

Biometrics (C) qualify as something you are, such as fingerprint scans, facial recognition, or iris scans. Using these two together easily establishes MFA.

Least privilege (B) is an authorization principle, not an MFA factor. LDAP (D) is a directory service protocol, not an MFA mechanism. Password vaulting (E) assists with credential storage but does not implement MFA. SAML (F) is a federation protocol used for Single Sign-On (SSO), not inherently MFA.

Thus, the correct MFA components are A: Authentication tokens and C: Biometrics.

Purchasing insurance is a classic example of risk transfer, where financial risk associated with potential losses is shifted to a third party (the insurer). This strategy does not eliminate the risk but moves the financial burden.

Mitigation (A) reduces risk impact or likelihood through controls, acceptance (B) involves acknowledging the risk without action, and avoidance (C) eliminates the risk by not engaging in the activity.

Risk transfer is a fundamental concept taught in the Risk Management domain of SY0-701【6:Chapter 17†CompTIA Security+ Study Guide】.

Steganography is the process of hiding information within another medium, such as an image, audio, video, or text file. The hidden information is not visible or noticeable to the casual observer, and can only be extracted by using a specific technique or key. Steganography can be used for various purposes, such as concealing secret messages, watermarking, or evading detection by antivirus software12

 Automation is the best way to consistently determine on a daily basis whether security settings on servers have been modified. Automation is the process of using software, hardware, or other tools to perform tasks that would otherwise require human intervention or manual effort. Automation can help to improve the efficiency, accuracy, and consistency of security operations, as well as reduce human errors and costs. Automation can be used to monitor, audit, and enforce security settings on servers, such as firewall rules, encryption keys, access controls, patch levels, and configuration files. Automation can also alert security personnel of any changes or anomalies that may indicate a security breach or compromise12.

The other options are not the best ways to consistently determine on a daily basis whether security settings on servers have been modified:

Compliance checklist: This is a document that lists the security requirements, standards, or best practices that an organization must follow or adhere to. A compliance checklist can help to ensure that the security settings on servers are aligned with the organizational policies and regulations, but it does not automatically detect or report any changes or modifications that may occur on a daily basis3.

Attestation: This is a process of verifying or confirming the validity or accuracy of a statement, claim, or fact. Attestation can be used to provide assurance or evidence that the security settings on servers are correct and authorized, but it does not continuously monitor or audit any changes or modifications that may occur on a daily basis4.

Manual audit: This is a process of examining or reviewing the security settings on servers by human inspectors or auditors. A manual audit can help to identify and correct any security issues or discrepancies on servers, but it is time-consuming, labor-intensive, and prone to human errors. A manual audit may not be feasible or practical to perform on a daily basis.

AnEndpoint Detection and Response (EDR)solution is designed tomonitor, detect, and respond to security incidents on endpoints (such as workstations and servers). Itcollects and analyzes data, detecting suspicious activity and forwarding relevant information for further investigation.

Network Access Control (NAC) (A)enforces network access policies but does not analyze security threats on hosts.

Intrusion Prevention Systems (IPS) (B)detect and block network threats but do not provide deep endpoint analytics.

Security Information and Event Management (SIEM) (C)aggregates logs and provides security analytics but lacks direct endpoint detection and response capabilities.

EDR is the best choicefor analyzing and responding to endpoint security incidents.
