organization has begun to use STRIDE to assess its software and has identified threat agents and the business impacts that these threats could have. Now they are working to identify appropriate controls for the issues they have identified.
1 Ben’s development team needs to address an authorization issue, resulting in an elevation of privilege threat. Which of the following controls is most appropriate to this type of issue?Auditing and logging are enabled.Role-based access control is used for specific operations.Data type and format checks are enabled.User input is tested against a whitelist.
2 Ben’s team is attempting to categorize a transaction identification issue that is caused by use of a symmetric key shared by multiple servers. What STRIDE category should this fall into?Information disclosureDenial of serviceTamperingRepudiation
3 Ben wants to prevent or detect tampering with data. Which of the following is not an appropriate solution?HashesDigital signaturesFilteringAuthorization controls
4 During a port scan of his network, Alex finds that a number of hosts respond on TCP ports 80, 443, 515, and 9100 in offices throughout his organization. What type of devices is Alex likely discovering?Web serversFile serversWireless access pointsPrinters

11 Bobbi is investigating a security incident and discovers that an attacker began with a normal user account but managed to exploit a system vulnerability to provide that account with administrative rights. What type of attack took place under the STRIDE threat model?SpoofingRepudiationTamperingElevation of privilege
For questions 50–53, please refer to the following scenario.
Ann is a security professional for a midsize business and typically handles log analysis and security monitoring tasks for her organization. One of her roles is to monitor alerts originating from the organization’s intrusion detection system. The system typically generates several dozen alerts each day, and many of those alerts turn out to be false alarms after her investigation.
This morning, the intrusion detection system alerted because the network began to receive an unusually high volume of inbound traffic. Ann received this alert and began looking into the origin of the traffic.
1 At this point in the incident response process, what term best describes what has occurred in Ann’s organization?Security occurrenceSecurity incidentSecurity eventSecurity intrusion
2 Ann continues her investigation and realizes that the traffic generating the alert is abnormally high volumes of inbound UDP traffic on port 53. What service typically uses this port?DNSSSH/SCPSSL/TLSHTTP
3 As Ann analyzes the traffic further, she realizes that the traffic is coming from many different sources and has overwhelmed the network, preventing legitimate uses. The inbound packets are responses to queries that she does not see in outbound traffic. The responses are abnormally large for their type. What type of attack should Ann suspect?ReconnaissanceMalicious codeSystem penetrationDenial of service
4 Now that Ann understands that an attack has taken place that violates her organization’s security policy, what term best describes what has occurred in Ann’s organization?Security occurrenceSecurity incidentSecurity eventSecurity intrusion
5 During a log review, Saria discovers a series of logs that show login failures, as shown here:Jan 31 11:39:12 ip-10-0-0-2 sshd[29092]: Invalid user admin from remotehost passwd=orange Jan 31 11:39:20 ip-10-0-0-2 sshd[29098]: Invalid user admin from remotehost passwd=Orang3 Jan 31 11:39:23 ip-10-0-0-2 sshd[29100]: Invalid user admin from remotehost passwd=Orange93 Jan 31 11:39:31 ip-10-0-0-2 sshd[29106]: Invalid user admin from remotehost passwd=Orangutan1 Jan 31 20:40:53 ip-10-0-0-254 sshd[30520]: Invalid user admin from remotehost passwd=OrangemonkeyWhat type of attack has Saria discovered?A brute-force attackA man-in-the-middle attackA dictionary attackA rainbow table attack
6 Ben is seeking a control objective framework that is widely accepted around the world and focuses specifically on information security controls. Which one of the following frameworks would best meet his needs?ITILISO 27002CMMPMBOK Guide
7 Alex is using nmap to perform port scanning of a system, and he receives three different port status messages in the results. Match each of the numbered status messages with the appropriate lettered description. You should use each item exactly once.Status messageOpenClosedFilteredDescriptionThe port is accessible on the remote system, but no application is accepting connections on that port.The port is not accessible on the remote system.The port is accessible on the remote system, and an application is accepting connections on that port.
8 Tony is developing a business continuity plan and is having difficulty prioritizing resources because of the difficulty of combining information about tangible and intangible assets. What would be the most effective risk assessment approach for him to use?Quantitative risk assessmentQualitative risk assessmentNeither quantitative nor qualitative risk assessmentCombination of quantitative and qualitative risk assessment
9 Angela wants to test a web browser’s handling of unexpected data using an automated tool. What tool should she choose?NmapzzufNessusNikto
10 Saria wants to log and review traffic information between parts of her network. What type of network logging should she enable on her routers to allow her to perform this analysis?Audit loggingFlow loggingTrace loggingRoute logging
11 Jim is working with a penetration testing contractor who proposes using Metasploit as part of her penetration testing effort. What should Jim expect to occur when Metasploit is used?Systems will be scanned for vulnerabilities.Systems will have known vulnerabilities exploited.Services will be probed for buffer overflow and other unknown flaws.Systems will be tested for zero-day exploits.
12 You are completing your business continuity planning effort and have decided that you wish to accept one of the risks. What should you do next?Implement new security controls to reduce the risk level.Design a disaster recovery plan.Repeat the business impact assessment.Document your decision-making process.
For questions 62–64, please refer to the following scenario. During a port scan, Ben uses nmap’s default settings and sees the following results.
1 If Ben is conducting a penetration test, what should his next step be after receiving these results?Connect to the
