Which of the following is a PRIMARY benefit of using a formalized security testing report format and structure?
Executive audiences will understand the outcomes of testing and most appropriate next steps for corrective actions to be taken
Technical teams will understand the testing objectives, testing strategies applied, and business risk associated with each vulnerability
Management teams will understand the testing objectives and reputational risk to the organization
Technical and management teams will better understand the testing objectives, results of each test phase, and potential impact levels
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:
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:
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.
A Virtual Machine (VM) environment has five guest Operating Systems (OS) and provides strong isolation. What MUST an administrator review to audit a user’s access to data files?
Host VM monitor audit logs
Guest OS access controls
Host VM access controls
Guest OS audit logs
Guest OS audit logs are what an administrator must review to audit a user’s access to data files in a VM environment that has five guest OS and provides strong isolation. A VM environment is a system that allows multiple virtual machines (VMs) to run on a single physical machine, each with its own OS and applications. A VM environment can provide several benefits, such as:
A guest OS is the OS that runs on a VM, which is different from the host OS that runs on the physical machine. A guest OS can have its own security controls and mechanisms, such as access controls, encryption, authentication, and audit logs. Audit logs are records that capture and store the information about the events and activities that occur within a system or a network, such as the access and usage of the data files. Audit logs can provide a reactive and detective layer of security by enabling the monitoring and analysis of the system or network behavior, and facilitating the investigation and response of the incidents.
Guest OS audit logs are what an administrator must review to audit a user’s access to data files in a VM environment that has five guest OS and provides strong isolation, because they can provide the most accurate and relevant information about the user’s actions and interactions with the data files on the VM. Guest OS audit logs can also help the administrator to identify and report any unauthorized or suspicious access or disclosure of the data files, and to recommend or implement any corrective or preventive actions.
The other options are not what an administrator must review to audit a user’s access to data files in a VM environment that has five guest OS and provides strong isolation, but rather what an administrator might review for other purposes or aspects. Host VM monitor audit logs are records that capture and store the information about the events and activities that occur on the host VM monitor, which is the software or hardware component that manages and controls the VMs on the physical machine. Host VM monitor audit logs can provide information about the performance, status, and configuration of the VMs, but they cannot provide information about the user’s access to data files on the VMs. Guest OS access controls are rules and mechanisms that regulate and restrict the access and permissions of the users and processes to the resources and services on the guest OS. Guest OS access controls can provide a proactive and preventive layer of security by enforcing the principles of least privilege, separation of duties, and need to know. However, guest OS access controls are not what an administrator must review to audit a user’s access to data files, but rather what an administrator must configure and implement to protect the data files. Host VM access controls are rules and mechanisms that regulate and restrict the access and permissions of the users and processes to the VMs on the physical machine. Host VM access controls can provide a granular and dynamic layer of security by defining and assigning the roles and permissions according to the organizational structure and policies. However, host VM access controls are not what an administrator must review to audit a user’s access to data files, but rather what an administrator must configure and implement to protect the VMs.
In which of the following programs is it MOST important to include the collection of security process data?
Quarterly access reviews
Security continuous monitoring
Business continuity testing
Annual security training
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:
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.
Which of the following could cause a Denial of Service (DoS) against an authentication system?
Encryption of audit logs
No archiving of audit logs
Hashing of audit logs
Remote access audit logs
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.
