ISC CISSP Exam Dumps - Actual Questions Answers

Remote access audit logs could cause a Denial of Service (DoS) against an authentication system. A DoS attack is a type of attack that aims to disrupt or degrade the availability or performance of a system or a network by overwhelming it with excessive or malicious traffic or requests. An authentication system is a system that verifies the identity and credentials of the users or entities that want to access the system or network resources or services. An authentication system can use various methods or factors to authenticate the users or entities, such as passwords, tokens, certificates, biometrics, or behavioral patterns.

Remote access audit logs are records that capture and store the information about the events and activities that occur when the users or entities access the system or network remotely, such as via the internet, VPN, or dial-up. Remote access audit logs can provide a reactive and detective layer of security by enabling the monitoring and analysis of the remote access behavior, and facilitating the investigation and response of the incidents.

Remote access audit logs could cause a DoS against an authentication system, because they could consume a large amount of disk space, memory, or bandwidth on the authentication system, especially if the remote access is frequent, intensive, or malicious. This could affect the performance or functionality of the authentication system, and prevent or delay the legitimate users or entities from accessing the system or network resources or services. For example, an attacker could launch a DoS attack against an authentication system by sending a large number of fake or invalid remote access requests, and generating a large amount of remote access audit logs that fill up the disk space or memory of the authentication system, and cause it to crash or slow down.

The other options are not the factors that could cause a DoS against an authentication system, but rather the factors that could improve or protect the authentication system. Encryption of audit logs is a technique that involves using a cryptographic algorithm and a key to transform the audit logs into an unreadable or unintelligible format, that can only be reversed or decrypted by authorized parties. Encryption of audit logs can enhance the security and confidentiality of the audit logs by preventing unauthorized access or disclosure of the sensitive information in the audit logs. However, encryption of audit logs could not cause a DoS against an authentication system, because it does not affect the availability or performance of the authentication system, but rather the integrity or privacy of the audit logs. No archiving of audit logs is a practice that involves not storing or transferring the audit logs to a separate or external storage device or location, such as a tape, disk, or cloud. No archiving of audit logs can reduce the security and availability of the audit logs by increasing the risk of loss or damage of the audit logs, and limiting the access or retrieval of the audit logs. However, no archiving of audit logs could not cause a DoS against an authentication system, because it does not affect the availability or performance of the authentication system, but rather the availability or preservation of the audit logs. Hashing of audit logs is a technique that involves using a hash function, such as MD5 or SHA, to generate a fixed-length and unique value, called a hash or a digest, that represents the audit logs. Hashing of audit logs can improve the security and integrity of the audit logs by verifying the authenticity or consistency of the audit logs, and detecting any modification or tampering of the audit logs. However, hashing of audit logs could not cause a DoS against an authentication system, because it does not affect the availability or performance of the authentication system, but rather the integrity or verification of the audit logs.

Technical and management teams will better understand the testing objectives, results of each test phase, and potential impact levels is the primary benefit of using a formalized security testing report format and structure. Security testing is a process that involves evaluating and verifying the security posture, vulnerabilities, and threats of a system or a network, using various methods and techniques, such as vulnerability assessment, penetration testing, code review, and compliance checks. Security testing can provide several benefits, such as:

• Improving the security and risk management of the system or network by identifying and addressing the security weaknesses and gaps
• Enhancing the security and decision making of the system or network by providing the evidence and information for the security analysis, evaluation, and reporting
• Increasing the security and improvement of the system or network by providing the feedback and input for the security response, remediation, and optimization

A security testing report is a document that summarizes and communicates the findings and recommendations of the security testing process to the relevant stakeholders, such as the technical and management teams. A security testing report can have various formats and structures, depending on the scope, purpose, and audience of the report. However, a formalized security testing report format and structure is one that follows a standard and consistent template, such as the one proposed by the National Institute of Standards and Technology (NIST) in the Special Publication 800-115, Technical Guide to Information Security Testing and Assessment. A formalized security testing report format and structure can have several components, such as:

• Executive summary: a brief overview of the security testing objectives, scope, methodology, results, and conclusions
• Introduction: a detailed description of the security testing background, purpose, scope, assumptions, limitations, and constraints
• Methodology: a detailed explanation of the security testing approach, techniques, tools, and procedures
• Results: a detailed presentation of the security testing findings, such as the vulnerabilities, threats, risks, and impact levels, organized by test phases or categories
• Recommendations: a detailed proposal of the security testing suggestions, such as the remediation, mitigation, or prevention strategies, prioritized by impact levels or risk ratings
• Conclusion: a brief summary of the security testing outcomes, implications, and future steps

Technical and management teams will better understand the testing objectives, results of each test phase, and potential impact levels is the primary benefit of using a formalized security testing report format and structure, because it can ensure that the security testing report is clear, comprehensive, and consistent, and that it provides the relevant and useful information for the technical and management teams to make informed and effective decisions and actions regarding the system or network security.

The other options are not the primary benefits of using a formalized security testing report format and structure, but rather secondary or specific benefits for different audiences or purposes. Executive audiences will understand the outcomes of testing and most appropriate next steps for corrective actions to be taken is a benefit of using a formalized security testing report format and structure, but it is not the primary benefit, because it is more relevant for the executive summary component of the report, which is a brief and high-level overview of the report, rather than the entire report. Technical teams will understand the testing objectives, testing strategies applied, and business risk associated with each vulnerability is a benefit of using a formalized security testing report format and structure, but it is not the primary benefit, because it is more relevant for the methodology and results components of the report, which are more technical and detailed parts of the report, rather than the entire report. Management teams will understand the testing objectives and reputational risk to the organization is a benefit of using a formalized security testing report format and structure, but it is not the primary benefit, because it is more relevant for the introduction and conclusion components of the report, which are more contextual and strategic parts of the report, rather than the entire report.

Security continuous monitoring is the program in which it is most important to include the collection of security process data. Security process data is the data that reflects the performance, effectiveness, and compliance of the security processes, such as the security policies, standards, procedures, and guidelines. Security process data can include metrics, indicators, logs, reports, and assessments. Security process data can provide several benefits, such as:

• Improving the security and risk management of the system by providing the visibility and awareness of the security posture, vulnerabilities, and threats
• Enhancing the security and decision making of the system by providing the evidence and information for the security analysis, evaluation, and reporting
• Increasing the security and improvement of the system by providing the feedback and input for the security response, remediation, and optimization

Security continuous monitoring is the program in which it is most important to include the collection of security process data, because it is the program that involves maintaining the ongoing awareness of the security status, events, and activities of the system. Security continuous monitoring can enable the system to detect and respond to any security issues or incidents in a timely and effective manner, and to adjust and improve the security controls and processes accordingly. Security continuous monitoring can also help the system to comply with the security requirements and standards from the internal or external authorities or frameworks.

The other options are not the programs in which it is most important to include the collection of security process data, but rather programs that have other objectives or scopes. Quarterly access reviews are programs that involve reviewing and verifying the user accounts and access rights on a quarterly basis. Quarterly access reviews can ensure that the user accounts and access rights are valid, authorized, and up to date, and that any inactive, expired, or unauthorized accounts or rights are removed or revoked. However, quarterly access reviews are not the programs in which it is most important to include the collection of security process data, because they are not focused on the security status, events, and activities of the system, but rather on the user accounts and access rights. Business continuity testing is a program that involves testing and validating the business continuity plan (BCP) and the disaster recovery plan (DRP) of the system. Business continuity testing can ensure that the system can continue or resume its critical functions and operations in case of a disruption or disaster, and that the system can meet the recovery objectives and requirements. However, business continuity testing is not the program in which it is most important to include the collection of security process data, because it is not focused on the security status, events, and activities of the system, but rather on the continuity and recovery of the system. Annual security training is a program that involves providing and updating the security knowledge and skills of the system users and staff on an annual basis. Annual security training can increase the security awareness and competence of the system users and staff, and reduce the human errors or risks that might compromise the system security. However, annual security training is not the program in which it is most important to include the collection of security process data, because it is not focused on the security status, events, and activities of the system, but rather on the security education and training of the system users and staff.
