Comprehensive Cybersecurity Assessment and Strategy Implementation 1. Project Title Full-Scope Penetration Testing and Security Hardening 2. Project Description We are seeking a highly experienced and certified cybersecurity professional or team to conduct a comprehensive security audit, penetration test, and implement essential security enhancements for our Web Application. Our goal is to proactively identify vulnerabilities, achieve a robust security posture, and ensure compliance with industry best practices. Target Environment: Target: E.g., A multi-tenant SaaS platform hosted on AWS/GCP, or a corporate LAN/VPN infrastructure. Key Technologies: E.g., Python/Django backend, React frontend, PostgreSQL database, Docker/Kubernetes. Data Sensitivity: E.g., Handles PII (Personally Identifiable Information) / Financial Data / General Corporate Data. 3. Scope of Work & Deliverables The successful freelancer will be responsible for the following key phases and deliverables: Phase 1: Assessment and Testing Vulnerability Assessment (VA): Conduct automated and manual scans to identify known security weaknesses in the infrastructure and application code. External Penetration Testing (Black Box): Attempt to exploit vulnerabilities from an external perspective, focusing on network perimeter and public-facing assets. Internal Penetration Testing (Grey Box/White Box): Test the authenticated environment and internal network (credentials will be provided), focusing on privilege escalation, misconfigurations, and lateral movement. Security Code Review: Review critical sections of the application source code for common security flaws (e.g., injection, insecure deserialization). Phase 2: Reporting and Remediation Strategy Detailed Findings Report: A professional, structured report detailing all identified vulnerabilities, including: CVSS score or equivalent severity rating (Critical, High, Medium, Low). Proof-of-Concept (PoC) for exploitable vulnerabilities. Clear, prioritized remediation recommendations for each finding. Security Hardening Strategy: A concise, actionable plan for long-term security improvements (e.g., WAF configuration, MFA implementation, least-privilege review). 4. Required Skills and Experience Certification: Relevant certifications (e.g., OSCP, CEH, CISSP, G-PEN) are highly preferred. Technical Proficiency: Deep expertise in one or more of the following: Web application security (OWASP Top 10, API security) Cloud security (AWS, Azure, or GCP hardening and misconfiguration). Network security and exploitation techniques (Metasploit, Nmap). Reporting: Proven track record of delivering clear, professional, and actionable technical reports to both technical teams (developers) and non-technical stakeholders (management). Communication: Fluent English communication (written and verbal) is essential for effective collaboration during remediation. 5. Project Timeline Duration: 2-3 weeks
