Implementing solutions to correct defects is a responsibility of the development function, not the quality assurance (QA) function. The QA function should ensure that the development process follows the established standards and methodologies, and that the defects are identified and reported. The QA function should not be involved in fixing the defects, as this would compromise its independence and objectivity.The other options are valid responsibilities of the QA function, and they should not raise concern for an IS auditor.Reference:CISA Review Manual (Digital Version)1, page 300.

The most important thing to assess when conducting a business impact analysis (BIA) is the completeness of critical asset inventory. This is because the critical asset inventory is the basis for identifying and prioritizing the business processes, functions, and resources that are essential for thecontinuity of operations. The critical asset inventory should include both tangible and intangible assets, such as hardware, software, data, personnel, facilities, contracts, and reputation. The critical asset inventory should also be updated regularly to reflect any changes in the business environment or needs.Reference:

Discovery sampling is a type of statistical sampling that's used when the expected error rate in the population is very low1.This method is designed to discover at least one instance of an attribute or condition in a population1.It's often used in auditing to uncover fraud or noncompliance with rules and regulations1.

What are sampling methods and how do you choose the best one?

Flooding the site with an excessive number of packets is an attack technique that will succeed because of an inherent security weakness in an Internet firewall. This type of attack is also known as a denial-of-service (DoS) attack or a distributed denial-of-service (DDoS) attack if it involves multiple sources. The aim of this attack is to overwhelm the network bandwidth or the processing capacity of the firewall or the target system, rendering it unable to respond to legitimate requests or perform its normal functions. An Internet firewall is a device or software that monitors andcontrols incoming and outgoing network traffic based on predefined rules. A firewall can block or allow traffic based on various criteria, such as source address, destination address, port number, protocol type, application type, etc. However, a firewall cannot prevent traffic from reaching its interface or distinguish between legitimate and malicious traffic based on its content or behavior. Therefore, a firewall is vulnerable to flooding attacks that exploit its limited resources. Phishing is an attack technique that involves sending fraudulent emails or messages that appear to come from legitimate sources, such as banks, government agencies, online services, etc., in order to trick recipients into revealing their personal or financial information, such as passwords, credit card numbers, bank account details, etc., or into clicking on malicious links or attachments that can infect their systems with malware or ransomware. Phishing does not exploit an inherent security weakness in an Internet firewall, but rather exploits human psychology and social engineering techniques. A firewall cannot prevent phishing emails or messages from reaching their intended targets, unless they contain some identifiable features that can be filtered out by the firewall rules. However, a firewall cannot detect or prevent users from responding to phishing emails or messages or from opening malicious links or attachments. Using a dictionary attack of encrypted passwords is an attack technique that involves trying to guess or crack passwords by using a list of common or likely passwords or by using a brute-force method that tries all possible combinations of characters. This type of attack does not exploit an inherent security weakness in an Internet firewall, but rather exploits weak or poorly chosen passwords or weak encryption algorithms. A firewall cannot prevent a dictionary attack of encrypted passwords, unless it has some mechanisms to detect and block repeated or suspicious login attempts or to enforce strong password policies. However, a firewall cannot protect passwords from being stolen or intercepted by other means, such as phishing, malware, keylogging, etc. Intercepting packets and viewing passwords is an attack technique that involves capturing and analyzing network traffic that contains sensitive information, such as passwords, credit card numbers, bank account details, etc., in order to use them for malicious purposes. This type of attack does not exploit an inherent security weakness in an Internet firewall, but rather exploits insecure or unencrypted network communication protocols or channels. A firewall cannot prevent packets from being intercepted and viewed by unauthorized parties, unless it has some mechanisms to encrypt or obfuscate the network traffic or to authenticate the source and destination of the traffic. However, a firewall cannot protect packets from being modified or tampered with by other means, such as man-in-the-middle attacks, replay attacks, etc.Reference:ISACA CISA Review Manual 27th Edition, page 300

A balanced scorecard is a framework that translates the IT strategy into measurable objectives, indicators, targets, and initiatives across four perspectives: financial, customer, internal process, and learning and growth. A balanced scorecard helps to monitor and evaluate how well the IT function is delivering value to the organization, achieving its strategic goals, and improving its capabilities and competencies. The other options are not the primary uses of a balanced scorecard, because they either focus on specific aspects of IT rather than the overall performance, or they are not directly related to the IT strategy.
