27 Security should be designed and integrated into the organization as a means to support and maintain the business objectives. However, the only way to know if the implemented security is sufficient is to test it. Which of the following is a procedure designed to test and perhaps bypass a system's security controls?Logging usage dataWar dialingPenetration testingDeploying secured desktop workstations

28 Security needs to be designed to support the business objectives, but it also needs to be legally defensible. To defend the security of an organization, a log of events and activities must be created. Auditing is a required factor to sustain and enforce what?AccountabilityConfidentialityAccessibilityRedundancy

29 Risk assessment is a process by which the assets, threats, probabilities, and likelihoods are evaluated in order to establish criticality prioritization. What is the formula used to compute the ALE?ALE = AV * EF * AROALE = ARO * EFALE = AV * AROALE = EF * ARO

30 Incident response plans, business continuity plans, and disaster recovery plans are crafted when implementing business-level redundancy. These plans are derived from the information obtained when performing a business impact assessment (BIA). What is the first step of the BIA process?Identification of prioritiesLikelihood assessmentRisk identificationResource prioritization

31 Many events can threaten the operation, existence, and stability of an organization. Some of those threats are human caused, whereas others are from natural events. Which of the following represent natural events that can pose a threat or risk to an organization?EarthquakeFloodTornadoAll of the above

32 What kind of recovery facility enables an organization to resume operations as quickly as possible, if not immediately, upon failure of the primary facility?Hot siteWarm siteCold siteAll of the above

34 Any evidence to be used in a court proceeding must abide by the Rules of Evidence to be admissible. What type of evidence refers to written documents that are brought into court to prove a fact?Best evidenceParol evidenceDocumentary evidenceTestimonial evidence

35 DevOps manager John is concerned with the CEO's plan to minimize his department and outsource code development to a foreign programming group. John has a meeting scheduled with the board of directors to encourage them to retain code development in house due to several concerns. Which of the following should John include in his presentation? (Choose all that apply.)Code from third parties will need to be manually reviewed for function and security.If the third party goes out of business, existing code may need to be abandoned.Third-party code development is always more expensive.A software escrow agreement should be established.

36 When TLS is being used to secure web communications, what URL prefix appears in the web browser address bar to signal this fact?SHTTP://TLS://FTPS://HTTPS://

37 A new update has been released by the vendor of an important software product that is an essential element of a critical business task. The chief security officer (CSO) indicates that the new software version needs to be tested and evaluated in a virtual lab, which has a cloned simulation of many of the company's production systems. Furthermore, the results of this evaluation must be reviewed before a decision is made as to whether the software update should be installed and, if so, when to install it. What security principle is the CSO demonstrating?Business continuity planning (BCP)OnboardingChange managementStatic analysis

38 What type of token device produces new time-derived passwords on a specific time interval that can be used only a single time when attempting to authenticate?HOTPHMACSAMLTOTP

39 Your organization is moving a significant portion of their data processing from an on-premises solution to the cloud. When evaluating a cloud service provider (CSP), which of the following is the most important security concern?Data retention policyNumber of customersHardware used to support VMsWhether they offer MaaS, IDaaS, and SaaS

40 Most software vulnerabilities exist because of a lack of secure or defensive coding practices used by the developers. Which of the following is not considered a secure coding technique? (Choose all that apply.)Using immutable systemsUsing stored proceduresUsing code signingUsing server-side validationOptimizing file sizesUsing third-party software libraries

1 C. Detective access controls are used to discover (and document) unwanted or unauthorized activity. Preventive access controls block the ability to perform unwanted activity. Deterrent access controls attempt to persuade the perpetrator not to perform unwanted activity. Corrective access controls restore a system to normal function in the event of a failure or system interruption.

2 D. Strong password choices are difficult to guess, unpredictable, and of specified minimum lengths to ensure that password entries cannot be computationally determined. They may be randomly generated and use all the alphabetic, numeric, and punctuation characters; they should never be written down or shared; they should not be stored in publicly accessible or generally readable locations; and they shouldn't be transmitted in the clear.

3 B. Network-based IDSs are usually able to detect the initiation of an attack or the ongoing attempts to perpetrate an attack (including denial of service, or DoS). They are, however, unable to provide information about whether an attack was successful or which specific systems, user accounts, files, or applications were affected. Host-based IDSs have some difficulty with detecting and tracking down DoS attacks. Vulnerability scanners don't detect DoS attacks; they test for possible vulnerabilities. Penetration testing may cause a DoS or test for DoS vulnerabilities, but it is not a detection tool.

4 B. Not all instances of DoS are the result of a malicious attack. Errors in coding OSs, services, and applications have resulted in DoS conditions. Some examples of this include a process failing to release control of the CPU or a service consuming system resources out of proportion to the service requests it is handling. Social engineering (i.e., pretending to be a technical manager) and sniffing (i.e., intercepting network traffic) are typically not considered DoS attacks. Sending message packets to a recipient who did not request them simply to be annoying may be a type of social engineering and it is definitely spam, but unless the volume of the messages is significant, it does not warrant the label of DoS.
