A company recently experienced a malicious attack on its cloud-based environment. The company successfully contained and eradicated the attack. A security engineer is performing incident response work. The security engineer needs to recover an Amazon RDS database cluster to the last known good version. The database cluster is configured to generate automated backups with a retention period of 14 days. The initial attack occurred 5 days ago at exactly 3:15 PM.
Which solution will meet this requirement?
Amazon RDS supports point-in-time recovery (PITR) using automated backups within the configured retention window. According to the AWS Certified Security -- Specialty Study Guide, PITR allows recovery to any second within the retention period, making it the most precise recovery method following a security incident.
By restoring the database cluster to a point just before the attack occurred, such as 3:14 PM, the security engineer ensures that the restored database reflects the last known good state without including malicious changes. This method is more accurate than restoring from snapshots, which are created at fixed intervals and may not align with the exact recovery time.
Options B and C rely on snapshot timing and may reintroduce compromised data. Option D restores to an arbitrary time and does not meet the requirement to recover to the last known good version.
AWS documentation explicitly recommends point-in-time recovery for incident response scenarios that require precise restoration.

A company creates AWS Lambda functions from container images that are stored in Amazon Elastic Container Registry (Amazon ECR). The company needs to identify any software vulnerabilities in the container images and any code vulnerabilities in the Lambda functions.
Which solution will meet these requirements?
Amazon Inspector is the AWS service designed specifically for vulnerability management across compute workloads, including Amazon ECR container images and AWS Lambda functions. According to the AWS Certified Security -- Specialty documentation, Amazon Inspector provides automated vulnerability assessments for container images stored in ECR by performing enhanced image scanning that identifies common vulnerabilities and exposures (CVEs) in operating systems and application dependencies.
Inspector also supports Lambda code scanning to analyze function packages and container-based Lambda images for known software vulnerabilities. Findings include severity ratings and remediation guidance, allowing security teams to identify and prioritize risks efficiently.
Amazon GuardDuty focuses on threat detection using behavioral analysis and does not perform static vulnerability scanning of container images or Lambda code. AWS Security Hub aggregates findings from other services but does not perform scanning itself.
AWS best practices recommend Amazon Inspector for vulnerability detection in container images and serverless workloads.

A company is running a new workload across accounts in an organization in AWS Organizations. All running resources must have a tag of CostCenter, and the tag must have one of three approved values. The company must enforce this policy and must prevent any changes of the CostCenter tag to a non-approved value.
Which solution will meet these requirements?
AWS Organizations tag policies are designed to standardize and govern tag keys and allowed values across accounts. AWS Certified Security -- Specialty documentation describes tag policies as a governance mechanism that helps enforce consistent tagging by specifying required tag keys and permitted values. To ensure every resource has the CostCenter tag at creation time, an SCP can deny create actions when aws:RequestTag/CostCenter is missing (null). This prevents resources from being created without the required tag. Tag policies then define the three approved values and can be configured to enforce or report noncompliance depending on supported services, ensuring that tag values remain within the allowed set and preventing drift to unapproved values. Compared with custom Lambda-based enforcement, this approach minimizes operational overhead and keeps enforcement within AWS native governance services. Option A partially addresses allowed values at request time but does not address ongoing governance as cleanly across many services. Option B is not preventive because Lambda runs after events and cannot reliably block all creations. Option D still relies on custom logic and is not as operationally efficient as tag policies plus SCP guardrails.

A company must capture AWS CloudTrail data events and must retain the logs for 7 years. The logs must be immutable and must be available to be searched by complex queries. The company also needs to visualize the data from the logs.
Which solution will meet these requirements MOST cost-effectively?
AWS CloudTrail Lake is purpose-built to store, query, and analyze CloudTrail events, including data events, without requiring additional infrastructure. The AWS Certified Security -- Specialty documentation explains that CloudTrail Lake provides immutable event storage with configurable retention periods, including multi-year retention, which satisfies long-term compliance requirements such as 7-year retention. Events are stored in an append-only, immutable format managed by AWS, reducing operational complexity.
CloudTrail Lake supports SQL-based queries for complex analysis directly against the event data, eliminating the need to export logs to other services for querying. Additionally, CloudTrail Lake includes built-in dashboards and integrations that enable visualization of event trends and patterns without standing up separate analytics or visualization platforms.
Option B is invalid because CloudTrail Event History only retains events for up to 90 days and does not support long-term retention or advanced querying. Option C introduces high operational overhead and cost by requiring persistent Amazon EMR clusters and additional services. Option D incurs ongoing ingestion, indexing, and storage costs for OpenSearch Service over a 7-year period, making it less cost-effective than CloudTrail Lake.
AWS documentation positions CloudTrail Lake as the most cost-effective and operationally efficient solution for long-term, queryable CloudTrail event storage and visualization.

A company has a PHP-based web application that uses Amazon S3 as an object store for user files. The S3 bucket is configured for server-side encryption with Amazon S3 managed keys (SSE-S3). New requirements mandate full control of encryption keys.
Which combination of steps must a security engineer take to meet these requirements? (Select THREE.)
SSE-S3 uses AWS-managed keys and does not provide customer control. AWS Certified Security -- Specialty documentation states that SSE-KMS with customer managed keys allows full control, auditing, and key rotation. The security engineer must first create a customer managed KMS key, then update the bucket to use SSE-KMS. Existing objects must be re-encrypted to ensure compliance.
SSE-C requires the application to manage keys, increasing complexity and risk. AWS managed keys do not meet the requirement for customer-controlled encryption.
