Audit

Auditing is the process of recording activity and systematically reviewing and analyzing the activity and system configurations. The primary purpose of auditing is to detect anomalies and identify potential threats or weaknesses in the environment. Proper auditing configurations can also help to meet compliance requirements. The process of auditing encompasses regular analysis of user behaviors and system logs in support of proactive security measures. Auditing is applicable to all systems used within an organization, from the front door of a building to accessing a file on a fileserver. It is considered more critical for regulated industries such as, healthcare, finance and government where compliance requirements demand stringent tracking of user and system activates.This mitigation can be implemented through the following measures: System Audit: - Use Case: Regularly assess system configurations to ensure compliance with organizational security policies. - Implementation: Use tools to scan for deviations from established benchmarks. Permission Audits: - Use Case: Review file and folder permissions to minimize the risk of unauthorized access or privilege escalation. - Implementation: Run access reviews to identify users or groups with excessive permissions. Software Audits: - Use Case: Identify outdated, unsupported, or insecure software that could serve as an attack vector. - Implementation: Use inventory and vulnerability scanning tools to detect outdated versions and recommend secure alternatives. Configuration Audits: - Use Case: Evaluate system and network configurations to ensure secure settings (e.g., disabled SMBv1, enabled MFA). - Implementation: Implement automated configuration scanning tools like SCAP (Security Content Automation Protocol) to identify non-compliant systems. Network Audits: - Use Case: Examine network traffic, firewall rules, and endpoint communications to identify unauthorized or insecure connections. - Implementation: Utilize tools such as Wireshark, or Zeek to monitor and log suspicious network behavior.

T1213.005 Messaging Applications

Preemptively search through communication services to find inappropriately shared data, and take actions to reduce exposure when found.

Enterprise T1666 Modify Cloud Resource Hierarchy

Periodically audit resource groups in the cloud management console to ensure that only expected items exist, especially close to the top of the hierarchy (e.g., AWS accounts and Azure subscriptions). Typically, top-level accounts (such as the AWS management account) should not contain any workloads or resources.(Citation: AWS Management Account Best Practices)

Enterprise T1530 Data from Cloud Storage

Frequently check permissions on cloud storage to ensure proper permissions are set to deny open or unprivileged access to resources.(Citation: Amazon S3 Security, 2019)

Administrators should perform an audit of all access lists and the permissions they have been granted to access web applications and services. This should be done extensively on all resources in order to establish a baseline, followed up on with periodic audits of new or updated resources. Suspicious accounts/credentials should be investigated and removed. Enable advanced auditing on ADFS. Check the success and failure audit options in the ADFS Management snap-in. Enable Audit Application Generated events on the AD FS farm via Group Policy Object.(Citation: FireEye ADFS)
