Domain 6 CISSP Exam: Security Assessment and Testing

Explanation: When conducting a third-party audit, a security practitioner should seek to answer questions related to the third-partys security program. This includes the standards they use for selecting controls and auditing their effectiveness. By doing so, the practitioner can assess whether the third-party has adequate controls in place to mitigate risks that could impact the organization.

Explanation: Responsible disclosure is the principle that the discoverer of a vulnerability has a responsibility to report the weakness to the organization in a timely manner and give the organization time to fix the vulnerability before publicly disclosing it.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 593 in PDF)

Explanation: Marking port scans from a vulnerability scanners IP address as nonsuspicious is essential to prevent security alerts and incident response processes from being triggered by legitimate vulnerability scanning. Vulnerability scanners perform many of the same actions as attackers, and identifying their activity as suspicious could result in unnecessary and costly incident response actions. By marking the scanners IP address as nonsuspicious, the security team can focus on responding to actual threats and vulnerabilities.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 552 in PDF)

Explanation: Synthetic transactions can be employed as a test mechanism for a variety of purposes, including SLA monitoring. Hosted or cloud-based services may guarantee certain levels of service, and synthetic transactions can be used to log into the application every hour to verify if the service meets the agreed level.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 564 in PDF)

Explanation: Vulnerability scanners may generate excessive traffic and lead to a DoS. This can affect network performance while detecting vulnerabilities. Excessive scanning can also generate false positives and alert the wrong people, leading to unnecessary panic or ignoring real incidents.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 551 in PDF)

Explanation: Full disclosure means reporting a vulnerability transparently to the organization responsible for fixing it as soon as possible. It is a philosophical argument that all discovered weaknesses should be reported fully and transparently to the responsible organization. While the goal of improving security is admirable, some vendors may not be open to researchers who attempt to report vulnerabilities.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 593 in PDF)

Explanation: Management support and sponsorship of security initiatives is crucial because it provides direction and support. Management review and approval of security process data should be performed to ensure that controls are functioning as intended; that is to say that they are reducing risks to an acceptable level and that previously accepted risks are still within acceptable parameters. Changes to the organizations operating environment can render controls ineffective, even if they were previously adequate to reduce risks. Examples include launching new lines of business, the addition of new systems or processes, new compliance or regulatory obligations, and organizational changes like mergers, acquisitions, and divestitures. Therefore, management needs to make informed decisions about identifying risks and mitigating actions.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 578 in PDF)

Explanation: According to the text, external testing may be advisable or even required in some cases, especially for legal or regulatory reasons, such as maturity assessments against a maturity model or compliance purposes like PCI-DSS, ISO 27001, and the U.S. governments Federal Risk and Authorization Management Program (FedRAMP), which all require the use of an independent, authorized third-party auditor or assessor. Compliance with these standards brings a certain level of assurance to the clients or other companies doing business with audited firms, which makes it important that the audits be performed by a third-party with no active conflict of interest (Source: CISSP Study Guide by Sybex).

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 546 in PDF)

Explanation: The purpose of the reporting phase in pen testing is to capture all activities performed, vulnerabilities found, and access achieved, and to provide recommendations to remediate any identified vulnerabilities. The report is usually presented in a formal meeting, which marks the end of the pen test engagement. The different parts of the report may be designed for different audiences, such as an executive summary for management and a more technically detailed report for IT staff.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 562 in PDF)

Explanation: A KPI is a performance indicator that uses metrics and provides context. It exists to identify how effectively controls are operating to mitigate risks, and provide notice if a control is ineffective, which indicates a risk that may be more likely to occur. When designing KPIs for the organizations security program, it is helpful to understand the information needed by the organization and essential to ensure the KPIs provide clear information to support decision making.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 583 in PDF)

Explanation: Vulnerability scanners can perform automated actions like filling in form fields on a web application to check for issues including Structured Query Language (SQL) injection or cross-site scripting (XSS). However, this testing data is obviously not real data that belongs in the system and can cause issues with reports or processes that expect valid data stored in the system.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 553 in PDF)

Explanation: Preventative technical processes include encryption of data and securing access to decryption keys, network access controls like virtual private networks (VPNs), and endpoint controls like host-based firewalls. Designing a technical metrics program should be done to measure the organizations effectiveness at implementing multilayered security. To do so, it is useful to capture metrics across categories like Prevent, Detect, and Respond. Therefore, the correct answer is C because preventative technical processes are measured in the Prevent category of technical metrics.

(Page 571 in PDF)

Explanation: Full disclosure argues that any time a weakness is discovered, it should be fully and transparently reported to the organization responsible for fixing it as soon as possible, which means immediate public disclosure of the vulnerability. Responsible disclosure, on the other hand, defines a responsibility for the discoverer to report a weakness to the organization in a timely manner and give them time to fix the vulnerability before publicly disclosing it.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 594 in PDF)

Explanation: When a situation arises where a risk cannot be treated, an exception must be granted. The key components of documenting an exception in the exception handling process include risk details, reason for the exception, compensating controls, an explicit decision of exception approval, and time. These components help to identify and explain the issue, provide reasoning for the exception, partially mitigate the risk with compensating controls, and to limit the time-frame for the exception.

Explanation: SOC 2 requires management to establish “performance measures,” as well as generate and use “relevant, quality information to support the functioning of internal control.” This framework focuses primarily on security and availability controls for systems that store, process, and/or transmit data. The other frameworks have similar requirements for management review and oversight, but do not specifically mention generating performance measures to support internal control.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 580 in PDF)

Explanation: To design a security metrics program, two key elements are essential. First, an understanding of the security program objectives is necessary as it provides the reference point for the metrics. Second, the security controls must provide a method of measurement or quantification. For example, if multifactor authentication is required for all logins, access control logs can be queried to determine if this requirement is enforced 100 percent of the time. Therefore, option D is correct.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 574 in PDF)

Explanation: An assessment involves evaluating the likelihood of a specific risk and measuring or estimating the impact of risks that could affect those assets, while an audit is a more formal process that involves a systematic analysis against a defined standard to determine if the object meets a set of criteria. Therefore, option B is the correct answer.

Ref: The Official ISC2 CISSP CBK Reference 6th Edition

(Page 542 in PDF)

Explanation: Defined rules of behavior provide guidelines and set ground rules for testers to follow, ensuring everyone involved in the testing process is safe and that testers do not accidentally cause a Business Interruption event or provoke external incidents. This also helps ensure that the pen testing engagement is properly managed, that proper documentation for the testing results, incident records, and reporting are available.

Explanation: A major consideration for organizations with mixed IT environments when choosing and configuring a vulnerability scanner is the platform support. This is because organizations with mixed IT environments may have different operating systems, such as Linux and Windows, which require different scanners. Thus, using a vulnerability scanner that supports multiple platforms ensures that a comprehensive assessment is conducted. Other factors such as legal, contractual, or regulatory obligations, or the depth, scope, or coverage of the scanner are also important considerations. However, platform support is a major consideration, especially for mixed IT environments.
