Ben’s 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

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.
