I’m looking for a seasoned database-security specialist to carry out a complete vulnerability review of my live environment, then harden it against current attack vectors. Scope • Perform a thorough security assessment, including misconfiguration checks, privilege audits, and penetration tests that stay within legal boundaries. • Deliver a detailed written report highlighting each vulnerability, its risk rating, and clear remediation steps. • Implement the agreed fixes, apply critical patches, tighten user privileges, and configure robust backup & recovery procedures. • Provide a concise runbook so future admins understand the new security posture. What to include in your bid Show me past work that demonstrates you have secured production databases before—case studies, before-and-after metrics, or client testimonials are ideal. Tools & expectations I’m flexible on the specific DBMS; what matters is a strong track record with common platforms such as MySQL, PostgreSQL, or Oracle and proficiency with industry-standard tools (e.g., SQLMap, Nmap, Wireshark, Vault). Timeline Please outline how quickly you can complete the assessment and initial remediation. I’ll review submissions on a rolling basis and reach out for a short chat to finalise scope and access logistics.

Which DB are you using now, MySQL or PostgreSQL? Is the database on the same server as the website or separate? Do you currently allow remote login to DB from outside? I went through your description carefully, this looks like a normal production hardening job. Hi, this is Ambar Shome, I work independently but also run Shome & Associates for larger projects. I’ve done database security cleanup before on live servers where site must stay running, so I usually start with audit first, then fix step-by-step. No problem. Normally I check config, users, ports, backups, logs, then apply fixes one by one so nothing breaks. Things I usually find in real systems: old DB users still active root / admin remote login open DB listening on public IP weak password or no policy backup running but restore not tested wrong folder permissions on data dir unused ports open on server missing minor security patches I also test access from outside using nmap / sqlmap to see what is visible, then close what should not be open. After that I write short notes so next admin knows what was changed. Not a long report, just clear steps. One thing to confirm — is your DB server directly exposed to internet now?

I have several database tables that first need to be extracted, then thoroughly cleaned and pre-processed so they are ready for downstream analytics work. The main focus is on tidying inconsistent field values, handling missing or duplicated records, normalising date-time formats, and outputting a well-structured dataset that analysts can plug straight into their BI tools. All work should be done in Python, relying primarily on Pandas and NumPy (feel free to pull in supporting libraries such as SQLAlchemy for the initial pulls if that speeds things up). I will provide read-only credentials to the source databases, a short data dictionary, and a checklist of the quality rules each column has to satisfy. Deliverables • A clean, merged dataset in CSV or parquet format • A fully commented Python script or notebook that reproduces the entire cleaning pipeline • A concise README explaining any assumptions and how to run the code I am aiming for code that is clear, reproducible, and efficient—nothing hidden behind proprietary GUIs. If this sounds straightforward to you, let’s get started.
