The Junior Vulnerability Manager will join the Security team and will be responsible for supporting the management of the vulnerability lifecycle, with a particular focus on the operation and improvement of the scanning process.

Key Responsibilities:

1. Operation and Maintenance of Vulnerability Scans:

• Scan Execution: Perform vulnerability scans using Nessus, including preparing network files to be scanned and validating scan status (often automated; occasional weekend work may be required).

• Troubleshooting: Diagnose and resolve issues when scans fail, including:

  • Network diagnostics (connectivity, port issues, Layer 2/3, next-hop configuration, routing, VLANs/Trunks).

  • Diagnosing issues in Nessus and the Operating System.

  • Analyzing and improving Python scripts responsible for scanning processes.

2. Automation and Data Handling:

• Script Development (Python/Bash/SQL): Develop, modify, and maintain scripts to automate vulnerability management tasks.

• Code Migration: Participate in converting Python 2 scripts to Python 3.

• Database Management (SQL): Retrieve and correlate asset lists with scan database information, create data insertion queries, and process results.

• Data Processing: Use tools such as Regex, Excel (Pivot Tables), and Bash to process, correlate, and prepare scan results for various purposes.

• Quarterly Preparation: Support automation for folder creation in Nessus and asset list processing.

3. Post-Scan and Vulnerability Management:

• Result Handling: Analyze scan results, improving scripts to prevent known false positives.

• Vulnerability Closure: Use Burp (or develop alternative Python scripts) to automate batch closure of resolved vulnerabilities.

• Security Analysis: Assess vulnerabilities to determine if they are false positives (requires basic security knowledge).

• Validation: Perform basic security validations (entry-level pentesting skills) to confirm vulnerability resolution.

• Risk Management: Apply basic risk management knowledge to evaluate and propose vulnerability parking timeframes.

4. Infrastructure and Planning:

• Planning: Map networks and schedule scans, considering average execution times and restrictions.

• System Configuration: Reinstall the operating system and configure Nessus on dedicated laptops (requires Unix knowledge).

• Asset Validation: Correlate new CMDB assets with the networks configured in planned scans (SQL, Bash, Python).

• Security Knowledge (for example knowledge of pentesting)
• Programming skills (Python)
• Network Knowledge
• Unix (important to know network commands, bash commands)
• SQL knowledge
• Brief knowledge of risk management
• Fluency in English and Portuguese.
