Which of the following findings should an IS auditor be MOST concerned about when performing an audit of backup and recovery and the offsite storage vault? There are three individuals with a key to enter the are Paper documents are also stored in the offsite vault. The offsite vault is located in a separate facility. Data files that are stored in the vault are synchronized.

D Choice A is incorrect because more than one person would typically need to have a key to the vault to ensure that individuals responsible for the offsite vault can take vacations and rotate duties. Choice B is not correct because an IS auditor would not be concerned with whether paper documents are stored in the offsite vault. In fact, paper documents, such as procedural documents and a copy of the contingency plan, would most likely be stored in the offsite vault, and the location of the vault is important, but not as important as the files being synchronized.

In a security server audit, focus should be placed on (choose all that apply): adequate user training system stability proper application licensing proper segregation of duties continuous and accurate audit trail

D E Security server audit always takes high priority because the security administrators who manage this not only have elevated privilege, but also model and create the user passwords. Are proper segregation of duties implemented and enforced and is technology and procedures in place to make sure there is a continuous and accurate audit trail?

Identify the true statement from below to correctly define Governance and Management as per COBIT's view. (Select Two) [WTCSFHAVXCISA] Management plans, builds, runs and monitors activities in alignment with the direction set by the governance body Governance ensures that stakeholder needs, conditions, and options are evaluated to determine balanced, agreed-on enterprise objectives Governance plans, builds, runs and monitors activities in alignment with the direction set by the governance body Management ensures that stakeholder needs, conditions, and options are evaluated to determine balanced, agreed-on enterprise objectives

A B COBIT's view on this key distinction between governance and management is: • Governance: Ensures that stakeholder needs, conditions, and options are evaluated to determine balanced, agreed-on enterprise objectives; direction is set through prioritization and decision-making; and performance and compliance are monitored against agreed-on direction and objectives • Management: Plans, builds, runs and monitors activities in alignment with the direction set by the governance body to achieve the enterprise objectives

Lorena, an information systems auditor with the Town Bank, is conducting a review of a business application. She requested a data flow diagram (DFD) from the auditee. How does a DFD assist Lorena in her work? Establish a summary graphical view of data paths and storage Establish a step-by-step data generation flow Establish a hierarchical data model Establish high-level data definitions

A Data flow diagrams (DFD) provide a view of data flow between upstream and downstream systems. The DFD also provides an understanding of where the data gets stored. Using this information a useful summary of data flow paths and storage can be established that helps to provide an easy to understand the succinct view of systems being audited.

Jim, an information security architect with the Cocoa Exports Company, is tasked to suggest protection for the wireless networks. Identify the best option from the following. Disable Dynamic Host Configuration Protocol (DHCP) at all wireless access points Enable Dynamic Host Configuration Protocol (DHCP) at selected wireless access points Enable Dynamic Host Configuration Protocol (DHCP) at all wireless access points Remove all wireless access points from the organization network

A Dynamic Host Configuration Protocol (DHCP) is used for assigning IP addresses, subnet mask and other parameters for networked computers and devices. This process, however, can be exploited by a malicious actor to understand the internal IP ranges of the organization. Disabling DHCP is the best option since the connecting computers and devices will be having a static IP and be less risky as compared to the dynamic allocation. Enabling DHCP at all wireless access points is the complete opposite of the best option. Selective enable/disable still has the risk. Completely removing wireless access points is not a feasible solution since it affects functionality.

Identify the most important action from the below for an employee who is terminated from service recently. [AFB] Removal of the organization's data from employee-owned devices Send internal communication to notify other employees Complete a backup of the employee's local files and emails Complete handover of employee's work files to another colleague

James, an information security architect with the Town Bank, is tasked to suggest protection against identity theft in the online banking application. Identify the best option from the following. [AFG] Implement multi-factor authentication (MFA) for customers Periodic review of customer access logs One-way hashing of customer passwords Allowing customer access only from pre-identified devices

A Multi-factor authentication (MFA) is an authentication method in which a user is granted access only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something the user and only the user knows) e.g. a PIN or a password, possession (something the user and only the user has) e.g. token, and inherence (something the user and only the user is) e.g. biometric. The remaining options do not provide robust and effective protection against identity theft or may be impractical to implement.

Palm Trading Company has seen a gradual increase in phishing and spear-phishing attacks on its corporate network recently. Identify the best control from the following to address this threat. Strong authentication A web application firewall (WAF) An intrusion detection system (IDS) User education

A Phishing and spear-phishing attacks can be mounted in various innovative ways, and user education may work as the best defense against such attacks. Organizations conduct test drills to simulate phishing attacks to see organization preparedness to deal with these on a regular basis. Other controls do not provide sufficient defense against phishing attacks. Spear phishing is an email or electronic communications scam targeted towards a specific individual, organization or business. Although often intended to steal data for malicious purposes, cybercriminals may also intend to install malware on a targeted user's computer.

Fair Lending is developing a resumption procedure in a cyberattack scenario. Identify the most critical action from the following in such a scenario. Quickly resume business by invoking business continuity plan Form an incident response team to deal with experts from Business, IT and Legal departments Perform loss and impact analysis and submit the insurance claim Engage external cyber forensic investigators company to gain a full understanding of the impact

A Quickly resumption of business operations is of utmost importance. The business continuity plan must include the procedure to be executed to cover cyberattack scenario. While other actions are important, they need to be conducted in the order of their criticality.

Identify control from following to help address a referential integrity issue a relational database management system Key constraints Database backup Real application cluster Domain constraints

A Referential integrity issues result in orphan records in child tables also known as dangling tuples. These are records in the referencing relation that do not have "counterparts" in the referenced relation i.e. parent table. Referential integrity issues can be addressed by establishing foreign key constraints. A key constraint limits the values that an attribute or a set of attributes can take. A foreign key constraint ensures that all child records do have a valid parent record. Domain constraints operate at the database schema level and do not help in referential integrity issues. Clustering and backups are important - however, not useful in this situation.

Peter, a system administrator, needs to select a control to provide the greatest assurance of server's operating system integrity. Identify the correct answer from the following Strong boot password for strong security Logging of events and activites, and appropriate monitoring Server configuration hardening Physical security control by protecting the server in a secure location

C OS security hardening guidelines can be developed that define how the OS should be configured. Hardening a system means to configure it in the most secure manner to prevent nonprivileged users from gaining the right to execute privileged instructions and thus take control of the entire machine, jeopardizing the OS's integrity. Protecting the server in a secure location and setting a boot password are good practices, but do not ensure that a user will not try to exploit logical vulnerabilities and compromise the OS. Activity logging has two weaknesses in this scenario: (i) it is a detective control (not a preventive one), and (ii) the attacker who already gained privileged access can modify logs or disable them.

Fair Lending has implemented a disaster recovery plan. In order to implement the optimum business continuity strategy, what would Fair Lending have considered: [AJC] Mean of the combined downtime and recovery cost Lowest recovery cost despite the highest downtime cost Lowest downtime cost despite the highest recovery cost The lowest sum of downtime cost and recovery cost

D Ideally, businesses would want to minimize both the downtime cost and recovery cost. The optimum business continuity strategy aims to keep both of them at the lowest possible mark. Highest recovery cost cannot be the optimum strategy, similarly, the highest downtime cost cannot be the optimum strategy either. The average of the combined downtime and recovery cost is a distractor.

Jamaica Foundry has installed Ethernet cable (an unshielded twisted pair (UTP) network) that is more than 100 meters long. Identify the potential negative effect caused by the length of the cable? Cross-talk Electromagnetic interference (EMI) Dispersion Attenuation

D Attenuation is the weakening of signals during transmission. Upon weakening of signlas, it begins to read a 1 for a 0, and the user may experience communication problems. UTP faces attenuation around 100 meters. UTP implementations are susceptible to other negative effects as well, however not due to the length of the UTP cable.

James, an information security architect with the Town Bank, is tasked to implement defense-in-depth security. Identify a valid example of the same from the following. [AJH] Implementing separate firewalls for segregated network segments Implementing strong network controls to segregate the corporate network from the data centre network Implementing two firewall products from two different vendors to ensure they provide the best coverage Implementing logical access management controls in addition to network firewalls

D A good cybersecurity architecture employs defense-in-depth principles which means a series of defensive mechanisms are layered in such an order to protect valuable data and information that if one mechanism fails, another steps up. Implementing logical access management controls in addition to network firewalls is a good example of this.

Jacob is a business continuity manager with Guava Trading Company. Identify the first step for Jacob to perform soon after the replacement of hardware at the primary data centre? Conduct a review the implementation report Conduct compatibility check with the hot site Walk-through the disaster recovery plan to ensure the plan is relevant Add the records for new hardware in the assets inventory and update the old one's status

D Assets inventory is the basic input for the business continuity/disaster recovery plan, and the plan must be updated to reflect changes in the information systems infrastructure.

Lorena, an information systems auditor with the Town Bank, is conducting a review of backup and batch processing outsourced to a managed service provider. Identify the next step for Lorena. Review service delivery report to the service level agreement (SLA) Conduct a full independent review of backup and batch processing Place reliance upon 3rd party audit report on service provider's operations Review the service provider contract with the organization

D Lorena should first review the service provider's contract with the organization for the right-to-audit clause, service level agreements, and performance of 3rd party audits on the service provider's operations. Based on the outcome of this step, the next steps can be identified which may very well range from placing reliance upon the audit report submitted by the MSP to conducting a full-scale independent audit on the MSP.

Lisa, an information systems auditor at a non-profit charitable organization, is reviewing the perimeter security controls. Lisa wants to verify if the firewall is configured in compliance with an organization's security policy. Identify the most effective method from the following to verify Review of firewall log files Review of firewall administration procedures Attestation by the firewall administrator Review of firewall parameter settings

D Perimeter security plays a vital role in effectively preventing and detecting most attacks on their networks. The proper implementation and maintenance of firewalls are of paramount importance for having a robust and effective perimeter security mechanism and compliance with the organization's security policy. Therefore, a review of firewall parameter settings is the best method to determine if the firewall is configured in compliance with an organization's security policy.

Julio, IT Head at Quick Micropayments, wants to ensure the independence of a quality assurance (QA) team. Identify an activity to be avoided to achieve the objective. Ensure compliance with software development methodology Check the testing assumptions Perform code review to ensure proper documentation Correct coding errors during the testing process

D Quality assurance (QA) team should not be made responsible for correcting coding errors during the testing / QA process as correction of code is not the responsibility of the QA team. Doing so would result in a violation of segregation of duties principles and would impair the team's independence.

Lorena, an information systems auditor with the Town Bank, is reviewing the adequacy of the bank's security awareness training program. Identify the best performance evaluation criterion from the following. Number of incidents with business or reputational impact Adequate funding for security initiatives commensurating with the level of risk and business impact Board-level awareness of critical information assets and focus on their protection Roles and responsibilities include accountability for information security

D Roles and responsibilities including a clear statement of accountability for information security is the best evaluation measure of the bank's security awareness training program.

Michelle is an information systems auditor at AZ Systems. She is reviewing the information systems tactical plan. While doing so, she should determine whether a strategic information technology planning methodology is in place there is a clear definition of the information systems mission and vision the plan correlates business objectives to information systems goals and objectives there is an integration of information systems and business staffs within projects

D The integration of IS and business staff in projects is an operational issue and should be considered while reviewing the short-range plan. A strategic plan would provide a framework for the IS short-range plan.

Identify from following a relevant parameter corresponding business appetite for the data loss. Service delivery objective Recovery time objective Maximum tolerable outages Recovery point objective

D The recovery point objective (RPO) is determined based on business acceptable data loss appetite in an operational disruption event. RPO indicates the earliest point in time in which it is acceptable to recover the data. Recovery Time Objective (RTO) is the amount of time allowed for the recovery of a business function or resource to an acceptable level after a disaster occurs. Service Delivery Objective (SDO) is the minimal level of services to be reached during the alternate process mode until the normal situation is restored. It is directly related to business needs. Maximum Tolerable Outage (MTO) is the maximum time the organization can support processing in alternate mode.

Identify the correct answer from the following to be included in an organization's information systems security policy? Identity of sensitive security features Inventory of key IT resources to be secured Relevant software security features Criteria for access authorization

D The security policy provides the broad framework of security including a definition of those authorized to grant access and the basis for granting the access. Other choices are more detailed and are likely candidates for inclusion in standards/procedures.

There are various methods of suppressing a data center fire. Identify the MOST effective and environmentally friendly method from the following. Water-based systems (sprinkler systems) Argonite systems Carbon dioxide systems Dry-pipe sprinkling systems

D, Dry-pipe sprinkling systems are the most effective and environmentally friendly from the available options. In this system, the water does not flow until the fire alarm activates a pump. Water-based systems (sprinkler systems) are environmentally friendly but may not present the most effective option. In this system, the water is always present in the piping, which can potentially leak, causing damage to equipment.

An information systems auditor with Super Systems wants review arrangements to protect against non-privileged users be able to escalate their access level to enter supervisory state. Identify the artifact that is useful to review for the identification of such arrangement/controls. Access control violations logs System access logs Access control software parameters System configuration files for control options used

D, The information systems auditor should review system configuration files for control options used to protect the supervisory state. These options, if uncontrolled, provide a nonprivileged user a way to gain access to the OS's supervisory state. A review of systems access logs and access violations logs is a detective control in nature. Access control software is run under the operating system.

The information system auditor discovers that both the technology and accounting functions are being performed by the same user of the financial system during a compliance audit of a small local cooperative bank. Identify the best supervisor review control from the following: Database table dump containing audit trails of date/time of each transaction Daily summary of number of transactions and sum total of value of each transaction User account administration report Computer log files that show individual transactions in the financial system

D, While other supervisory review controls are important, the most important in this situation is to review the computer log files that show individual transactions in the financial system

Lisa, an information systems auditor at the AZ Systems, while conducting the review of the UNIX system administration function, observed that shared user id is used by the team of ten administrators. Identify the concern that Lisa may have with this observation Risk of passwords not being reset on the desired frequency Risk of an outsider be able to gain unauthorized access No concern since the user ids are only shared amongst the administrators Difficulty in tracing admin actions and dilution of accountability

D. If one user id is shared amongst multiple administrators, there is no clear traceability of performed activities to an identifiable individual. This leads to the dilution of accountability and is a risk. Additionally, this may lead to weak account lifecycle management and also exposes to the risk of passwords being leaked to an outsider due to dilution of accountability.

Andrew, CFO of Palm Trading Company, a relatively smaller organization, wants to implement segregation of duties for information processing facility (IPF) roles. Considering this requirement, identify a false statement from the following A network administrator normally would be restricted from reporting to the end-user manager A network administrator normally would be restricted from having additional end-user responsibilities A network administrator normally would be restricted from being responsible for network security administration A network administrator normally would be restricted from having programming responsibilities

D. The computer room and support areas in any organization usually make up the information processing facility (IPF). many organizations have widely dispersed IPFs in addition to a central IPF. The dispersed IPFs include the management of network at branches and geographically remote locations. Under these circumstances, a network administrator may have additional network security administration and end-user responsibilities and may report to an end-user manager. However, a network administrator is not allowed to have programming responsibilities to ensure objectives of segregation of duties are met.

Palm Trading Company has implemented digital signatures to protect email communication with their customers. Identify the benefit of using a digital signature from the following. Protects email content from unauthorized reading Protects email content from data theft Ensure timely delivery of email content Ensures integrity of the email content

D. The digital signature is used for verifying the identity of the sender and the integrity of the content.

Identify an example of an overlapping control from the following. Access controls via the use of electronic badges and visual verification by a security guard Identification badges (photo IDs) to be worn and displayed at all times Identification badges containing biometric data in a smart-chip in addition to the name and photo of the bearer Access controls via the use of electronic badges and strong system password

Overlapping control is when more than one control in place and either of the control is adequate to achieve the objective. For example, if a facility controls physical access via the use of electronic badges followed by the visual verification by a security guard.

Easy Micropayments has an online payment platform for customers to on-demand initiate payments during business hours. As the new payments are processed, the transactions are recorded on the disk as well as on the tape. The payment files at the end of the day are backed up on the tape. However, it was observed that during the backup process the files in hard disk as well as in the tape were corrupted due to the malfunction of the backup mechanism. Identify from following the best option to quickly and accurately restore the payment data to resume the online payment operations. The previous day's payment file from the disk and the today's transactions from tape The previous day's payment file from tape and today's payment transaction from the disk Today's payment transactions from the disk and the previous day's payment file from the tape Today's payment file from tape and the today's payment transactions from the disk

Restoring the previous day's payment files from the tape is the latest reliable backup on the tape. Today's transactions are easily and reliably retrievable from the disk. These two together will provide the best option to reliably and quickly re-create the most up to date and accurate data set for the system to resume operations.

Identify from following valid disk-based backup systems. Real application cluster Log shipping Host-based replication Virtual tape libraries

Virtual tape libraries (VTLs) systems consist of disk storage and software that control backup and recovery data sets. Host-based replication is executed at the host level by a special software running on this server and on the target server. Log shipping and real application cluster are not relevant to disk-based backup systems.

Identify a false statement pertaining to Wi-Fi Protected Access (WPA) in wireless networks from the following. WPA-PSK uses preshared keys for simpler implementation and management WPA allows unencrypted source addresses for backward compatibility WPA-EAP uses more stringent 802.1x authentication with the Extensible Authentication Protocol (EAP) WPA depends on a central authentication server to authenticate each user

WPA does not allow unencrypted source addresses. Rest are true statements about WPA.
