This is crucial within a Zero Trust architecture, which assumes that no entity (internal or external) is inherently trustworthy. By limiting access to only necessary network segments, microsegmentation reduces the impact of a potential breach by containing it within a limited area. CompTIA emphasizes microsegmentation as an effective strategy to minimize risk and improve security posture by isolating resources based on the principle of least privilege.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(1,this)' id='btn-1' value='See Answer'  \/><input type='hidden' id='questionType1' value='radio' class=''><\/div><div class='watu-question' id='question-2'><div class='question-content'><p><strong>Q123.<\/strong> Which of the following describes the importance of an organization understanding SLOs when outsourcing incident response to a third party?<\/p>\n<\/div><input type='hidden' name='question_id[]' value='18175' \/><div class='watu-questions-wrap '><input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70071' \/><div class='watu-question-choice'><input type='radio' name='answer-18175[]' id='answer-id-70071' class='answer answer-2 php-answer-label answerof-18175' value='70071' \/>&nbsp;<label for='answer-id-70071' id='answer-label-70071' class='php-answer-label answer label-2'><span class='answer'>To track the performance of specific KPIs<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70072' \/><div class='watu-question-choice'><input type='radio' name='answer-18175[]' id='answer-id-70072' class='answer answer-2 js-answer-label answerof-18175' value='70072' \/>&nbsp;<label for='answer-id-70072' id='answer-label-70072' class='js-answer-label answer label-2'><span class='answer'>To understand the hidden costs of an SLA<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70073' \/><div class='watu-question-choice'><input type='radio' name='answer-18175[]' id='answer-id-70073' class='answer answer-2 js-answer-label answerof-18175' value='70073' \/>&nbsp;<label for='answer-id-70073' id='answer-label-70073' class='js-answer-label answer label-2'><span class='answer'>To ensure that an objective risk score can be calculated<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70074' \/><div class='watu-question-choice'><input type='radio' name='answer-18175[]' id='answer-id-70074' class='answer answer-2 js-answer-label answerof-18175' value='70074' \/>&nbsp;<label for='answer-id-70074' id='answer-label-70074' class='js-answer-label answer label-2'><span class='answer'>To quantify the risk appetite in an MOU<\/span><\/label><\/div>\n<\/div><div class='show-question-feedback' style='display:none;'>The correct answer is A . SLOs &#8211; service-level objectives &#8211; are measurable targets used to determine whether a service provider is meeting expected performance requirements. When incident response is outsourced, the organization needs SLOs to measure third-party performance against KPIs such as response time, remediation time, reporting timeliness, and service effectiveness.<br\/>The Secbay CySA+ guide states that SLOs are &#8220;specific, measurable targets&#8221; for the performance and reliability of a service or process. It also explains that SLO reporting includes achievement summaries, trend analysis, and deviations from expected performance.<br\/>The official CySA+ objectives include SLOs under metrics and KPIs, and incident response reporting includes metrics such as mean time to detect, mean time to respond, mean time to remediate, and alert volume. The Sybex CySA+ Study Guide also states that SLOs define metrics such as time to remediate or patch and are often part of vendor or service agreements.<br\/>Why the other options are incorrect:<br\/>B is incorrect because SLOs are not primarily for finding hidden costs.<br\/>C is incorrect because SLOs do not calculate a risk score.<br\/>D is incorrect because risk appetite belongs to governance and risk management, not SLO measurement.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(2,this)' id='btn-2' value='See Answer'  \/><input type='hidden' id='questionType2' value='radio' class=''><\/div><div class='watu-question' id='question-3'><div class='question-content'><p><strong>Q124.<\/strong> A security analyst has found a moderate-risk item in an organization&#8217;s point-of-sale application.

Business process interruption is when the remediation of a vulnerability or an incident requires the disruption or suspension of a critical or essential business process, such as the point-of-sale application. This can cause operational, financial, or reputational losses for the organization, and may outweigh the benefits of the remediation.<br\/>Therefore, the organization may decide to postpone or avoid the remediation until a more convenient time, such as a change freeze window, which is a period of time when no changes are allowed to the IT environment12. Service-level agreement, degrading functionality, and proprietary system are other possible inhibitors to remediation, but they are not relevant to this scenario. Service-level agreement is when the remediation of a vulnerability or an incident violates or affects the contractual obligations or expectations of the service provider or the customer. Degrading functionality is when the remediation of a vulnerability or an incident reduces or impairs the performance or usability of a system or an application. Proprietary system is when the remediation of a vulnerability or an incident involves a system or an application that is owned or controlled by a third party, and the organization has limited or no access or authority to modify it3.<br\/>References: Inhibitors to Remediation &#8211; SOC Ops Simplified, Remediation Inhibitors &#8211; CompTIA CySA+, Information security Vulnerability Management Report (Remediation&#8230;<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(3,this)' id='btn-3' value='See Answer'  \/><input type='hidden' id='questionType3' value='radio' class=''><\/div><div class='watu-question' id='question-4'><div class='question-content'><p><strong>Q125.<\/strong> A web vulnerability scanner has identified many instances of poorly written code that allow for path traversal.<br \/>Which of the following is the best option for rewriting the code?<\/p>\n<\/div><input type='hidden' name='question_id[]' value='18177' \/><div class='watu-questions-wrap '><input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70079' \/><div class='watu-question-choice'><input type='radio' name='answer-18177[]' id='answer-id-70079' class='answer answer-4 php-answer-label answerof-18177' value='70079' \/>&nbsp;<label for='answer-id-70079' id='answer-label-70079' class='php-answer-label answer label-4'><span class='answer'>Sanitize the user-supplied file and directory names in the application input.<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70080' \/><div class='watu-question-choice'><input type='radio' name='answer-18177[]' id='answer-id-70080' class='answer answer-4 js-answer-label answerof-18177' value='70080' \/>&nbsp;<label for='answer-id-70080' id='answer-label-70080' class='js-answer-label answer label-4'><span class='answer'>Validate or encode the application output.<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70081' \/><div class='watu-question-choice'><input type='radio' name='answer-18177[]' id='answer-id-70081' class='answer answer-4 js-answer-label answerof-18177' value='70081' \/>&nbsp;<label for='answer-id-70081' id='answer-label-70081' class='js-answer-label answer label-4'><span class='answer'>Scrub SQL commands that were entered by users into text input fields.<\/span><\/label><\/div>\n<input type='hidden' name='answer_ids[]' class='watu-answer-ids' value='70082' \/><div class='watu-question-choice'><input type='radio' name='answer-18177[]' id='answer-id-70082' class='answer answer-4 js-answer-label answerof-18177' value='70082' \/>&nbsp;<label for='answer-id-70082' id='answer-label-70082' class='js-answer-label answer label-4'><span class='answer'>Limit the privilege level of the web applications.<\/span><\/label><\/div>\n<\/div><div class='show-question-feedback' style='display:none;'>The correct answer is A because path traversal, also called directory traversal, occurs when an attacker manipulates file or directory path input, such as ..\/, to access files outside the intended directory. The best code-level fix is to validate and sanitize user-supplied file and directory names so the application does not accept traversal sequences or malicious path characters.<br\/>Exact supporting extract: the Sybex CySA+ Study Guide explains that a directory traversal attack occurs when an attacker inserts filesystem path values into a query string to access files outside the authorized area.<br\/>It also states that controls should include avoiding filenames in user-manipulatable fields and using input validation to prevent special characters required for directory traversal.<br\/>The All-in-One CySA+ guide also states that directory traversal mitigations include input validation to ensure user input does not contain directory traversal sequences and filename sanitization to remove directory traversal sequences or other malicious characters.<br\/>Why the other options are incorrect:<br\/>B is incorrect because output encoding is mainly used to prevent output-based attacks such as XSS.<br\/>C is incorrect because scrubbing SQL commands relates to SQL injection, not path traversal.<br\/>D is a useful defense-in-depth measure, but it does not directly rewrite the vulnerable code to prevent path traversal.<\/div><input type='button' class='showchecked' style='margin: 10px 0;' onclick='showanswer1(4,this)' id='btn-4' value='See Answer'  \/><input type='hidden' id='questionType4' value='radio' class=''><\/div><div class='watu-question' id='question-5'><div class='question-content'><p><strong>Q126.<\/strong> A penetration tester is conducting a test on an organization &#8216; s software development website.

Implanted a backdoor.<br\/>A backdoor is a method that allows an unauthorized user to access a system or network without the permission or knowledge of the owner. A backdoor can be installed by exploiting a software vulnerability, by using malware, or by physically modifying the hardware or firmware of the device. A backdoor can be used for various malicious purposes, such as stealing data, installing malware, executing commands, or taking control of the system.<br\/>In this case, the consultant implanted a backdoor in the website by using an HTML and PHP code snippet that displays an image of a shutdown button and an alert message that says &#8220;Exit&#8221;. However, the code also echoes the remote address of the server, which means that it sends the IP address of the visitor to the attacker. This way, the attacker can identify and target the visitors of the website and use their IP addresses to launch further attacks or gain access to their devices.<br\/>The code snippet is an example of a clickjacking attack, which is a type of interface-based attack that tricks a user into clicking on a hidden or disguised element on a webpage. However, clickjacking is not the main goal of the consultant, but rather a means to implant the backdoor. Therefore, option C is incorrect.<br\/>Option B is also incorrect because privilege escalation is an attack technique that allows an attacker to gain higher or more permissions than they are supposed to have on a system or network. Privilege escalation can be achieved by exploiting a software vulnerability, by using malware, or by abusing misconfigurations or weak access controls. However, there is no evidence that the consultant implemented privilege escalation on the website or gained any elevated privileges.<br\/>Option D is also incorrect because patching is a process of applying updates to software to fix errors, improve performance, or enhance security. Patching can prevent or mitigate various types of attacks, such as exploits, malware infections, or denial-of-service attacks. However, there is no indication that the consultant patched the web server or improved its security in any way.<br\/>References:<br\/>1 What Is a Backdoor &amp; How to Prevent Backdoor Attacks (2023)<br\/>2 What is Clickjacking?

By cross-referencing the signature with these sources, the analyst can determine the type of malware and its telemetry.

The book also covers the usage and syntax of EDR, a tool used for endpoint security, in chapter 5. Specifically, it explains the meaning and function of malware signatures and how they can be used to identify malware types1, page 203.
