When encrypting data, two fundamental drivers of cryptographic strength are the algorithm you choose and the key length you use (which affects brute-force feasibility and overall security margin). The Study Guide emphasizes algorithm selection as a best practice: “First, choose your encryption system wisely… Choose an encryption system with an algorithm in the public domain that has been thoroughly vetted by industry experts.” It then highlights key selection/size as another central decision: “You must also select your keys in an appropriate manner. Use a key length that balances your security requirements with performance considerations.”

These two choices directly affect whether encryption meaningfully protects confidentiality. By contrast, obfuscation, masking, and tokenization are different data-protection techniques (often used to reduce exposure or de-identify data) rather than core encryption-strength parameters. Salting is primarily associated with strengthening password hashing (defending against rainbow table attacks), not selecting encryption primitives/strength for general data encryption. Therefore, the best two considerations in the context of encryption itself are Algorithms and Key length.

Cross-site scripting, or XSS, is the correct answer because it involves injecting malicious script into web content that executes in a user’s browser. If an application fails to validate or encode input properly, an attacker can cause the browser to run externally supplied JavaScript. This can allow session theft, credential harvesting, browser redirection, page manipulation, or actions performed as the victim. A secure web gateway, or SWG, is a defensive control, not an attack vulnerability. Denial of service focuses on disrupting availability, not controlling a browser through script execution. SQL injection targets backend database queries rather than browser-side script execution. The phrase “externally injected script” strongly identifies XSS as the exploited vulnerability.

This describes a time-of-use issue, commonly associated with time-of-check to time-of-use race conditions. The key clue is that the user authenticates, but the unauthorized write operation occurs seconds later when the website is under heavy load. In a race condition, the application checks a security condition at one point in time but uses the result later, after the state may have changed. Heavy load can widen this timing gap and make exploitation more likely. CSRF tricks an authenticated user’s browser into submitting an unwanted request. SQLi injects malicious SQL into database queries. XSS injects scripts into web pages viewed by users. Because the issue is caused by timing between authentication and write execution, TOU is the best answer.

The malicious IP address is 118.19.200.55 because the log entry includes a SQL statement: SELECT * FROM company WHERE keyword = ' VP. That pattern strongly indicates an attempted SQL injection or database query manipulation through a web search endpoint. In Security+ threat and vulnerability analysis, SQL injection is an application attack in which an attacker places database commands into input fields or URL parameters to retrieve, alter, or destroy data. The 132.18.62.144 entry also shows suspicious directory traversal syntax using ../, but the question asks for the most likely malicious attempt among the listed entries; the explicit SQL query in a POST request is the clearest indicator. Normal GET requests and 404 errors alone are less conclusive.

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.

Peer review and approval is a practice that involves having other developers or experts review the code before it is deployed or released. Peer review and approval can help detect and prevent malicious code, errors, bugs, vulnerabilities, and poor quality in the development process. Peer review and approval can also enforce coding standards, best practices, and compliance requirements. Peer review and approval can be done manually or with the help of tools, such as code analysis, code review, and code signing. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 11: Secure Application Development, page 543 2

SASE stands for Secure Access Service Edge. It is a cloud-based service that combines network and security functions into a single integrated solution. SASE can help reduce traffic on the VPN and internet circuit by providing secure and optimized access to the data center and cloud applications for remote employees. SASE can also monitor and enforce security policies on the remote employee internet traffic, regardless of their location or device. SASE can offer benefits such as lower costs, improved performance, scalability, and flexibility compared to traditional VPN solutions. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 457-458 1
