Security Log Review Summary

Date: November 8, 2024
Author: Kevin McCaffrey

Summary of Findings

1. Unauthorized Access Attempts
During the security log analysis, multiple unauthorized access attempts were detected. These attempts primarily targeted sensitive API endpoints and occurred during non-business hours, suggesting potential malicious intent. The IP addresses involved were traced to several regions known for cyber threats, which were subsequently flagged for further investigation.

2. Vulnerabilities Identified
The log analysis also revealed certain vulnerabilities, including weak authentication mechanisms for some internal services. Additionally, a lack of proper input validation was observed in some user-facing components, increasing the risk of injection attacks. Several outdated security certificates were identified, which may pose a risk if not updated promptly.

3. Recommended Actions
To address the identified issues, the following actions are recommended:

• Strengthen Authentication: Implement multi-factor authentication (MFA) for all sensitive endpoints and enhance password policies.
• Input Validation: Conduct a review of input handling across user-facing components and enforce stricter input validation measures to prevent injection attacks.
• Certificate Updates: Replace outdated security certificates with updated versions to ensure secure communications.
• Monitoring and Alerting: Set up real-time monitoring and alerting for unauthorized access attempts, particularly for access during non-business hours or from suspicious regions.

Tools and Technologies Used

• Log Aggregation: Amazon CloudWatch Logs for collecting security events
• Analysis: AWS CloudTrail for tracking API activity and identifying suspicious patterns
• Automation: AWS Lambda for automated alerting on unauthorized access attempts

Roles Involved

• Security Analyst: Analyzed security logs to identify unauthorized access attempts and system vulnerabilities. Developed recommendations for addressing identified issues.
• DevOps Engineer: Responsible for implementing the recommended actions, including enhancing authentication mechanisms and updating security certificates.

Artifacts Created

• Security Log Review Summary: This document provides an overview of unauthorized access attempts, vulnerabilities, and recommended actions to improve security posture.
• Alerting Configuration: Updated alerting configurations in AWS to notify relevant teams of suspicious activities in real-time.
