Optimize Network Security Projects on Upwork

I am looking for an experienced Synology NAS expert to review and verify the security of my current NAS setup.

I have a Synology DS925+ which has already been set up (DSM installed, storage pool created, users, folders and permissions configured). During DSM installation, a volume encryption key (.rkey) was created.

What I need is a security-focused review, not a full reinstallation.

Scope of work:
• Review current DSM configuration
• Verify volume encryption and explain security behavior clearly
• Confirm best practices around volume key usage
• Review physical security settings (reset button, admin access)
• Check user & permission setup
• Advise on hardening and security best practices
• Explain threat scenarios (theft, reset, reboot, etc.)

Important:
• I want to understand the setup, not just have it changed
• Prefer screen sharing / Zoom and explanation while reviewing
• No risky changes without discussion
• This should take hours, not weeks

I’m looking for cyber security expert ethical hacker protect my social media profile from someone defaming my name by making ai videos and ai voice using my name. I would like to get the details of that profile and need guidance to remove cyber attacked videos.

I need an experienced ethical hacker to carry out a full penetration test on my in-development game. The focus is strictly security: I want to uncover any exploits that could let players gain unfair advantages, access restricted data, or crash servers before we launch.

Here’s what I expect from you:
• Map the game’s network traffic, APIs, and authentication flow, then probe for weaknesses using standard penetration-testing tools such as Burp Suite, Metasploit, Wireshark, or anything else you trust.
• Attempt privilege escalation inside both the client and server environments.
• Document every finding with clear replication steps, risk level, and suggested remediation.
• Deliver a final report and a short debrief call so we can walk through critical issues together.

You will receive temporary credentials to our staging servers plus any build files you need. The engagement ends once I have a verified report and we confirm that your stated vulnerabilities are either patched or fully understood on our side.

If you’re ready to dive in and break things—for the right reasons—let’s talk.

I have several upcoming roll-outs that centre on Palo Alto technologies and I need an engineer who can take a deployment from blank rack space to a fully documented, production-ready environment. The core of the job is Palo Alto firewall setup and configuration, site-to-site and remote-access VPN creation, plus ongoing threat management and response tuning.

Most of the current estate is mixed—Cisco switches and routers, Fortinet appliances at a few branches, with Trend Micro on the endpoint side—so any cross-vendor familiarity you possess will be welcome. That said, deep, hands-on Palo Alto knowledge is non-negotiable.

I’m based in Hyderabad and would prefer someone local (or elsewhere in India) who can be on-site when needed, especially for the initial rack/stack, cable verification and cut-over weekend.

When you message me, focus on your relevant experience: the size and type of deployments you have completed, versions of PAN-OS you’ve worked with, and any successful migrations from Cisco ASA or Fortinet to Palo Alto you have led.

Deliverables (to be handed over at project close):
• Working Palo Alto configuration files and validated run-book
• VPN profiles with accompanying user or peer documentation
• Threat-profile tuning report and suggested ongoing playbooks
• A concise, final network diagram in Visio or Draw.io

Acceptance criteria:
• All firewalls pass commit with zero errors and best-practice warnings addressed
• VPN tunnels up and stable for 48 hrs post-cut-over
• Threat logs verify policy hits and automated actions as designed
• Documentation reviewed and signed off during knowledge-transfer session

If this aligns with your skill set, let’s talk.

Skills: System Admin, Linux, Cisco, Network Administration, Documentation, Network Security, VPN, Draw.io

I’m looking for a networking professional with a minimum of five years of solid, hands-on experience. The role will see you diving straight into my existing infrastructure, tightening configurations, improving reliability, and making sure everything is fully documented so anyone can pick up where you leave off.

Day-to-day, you should be comfortable tackling whatever the environment throws at you—whether that means optimising switch and router configs, hardening firewall rules, or sorting out a stubborn server-side connectivity issue. Clear communication and concise change logs are essential; I need to know what was done, why it was done, and how to roll back if required.

Deliverables I expect:
• A brief assessment of the current network state and priority recommendations
• Updated, best-practice configurations applied and tested
• Clean documentation of every change (text or diagrams are fine)
• Availability for follow-up troubleshooting during an agreed support window

If you thrive on solving real-world networking problems and have the track record to prove it, I’d love to hear how you can help.

Quiero someter mi sitio web a una prueba de penetración de caja negra enfocada exclusivamente en la seguridad de la base de datos SQL. No facilitaré credenciales ni información interna: la idea es replicar el punto de vista de un atacante externo y comprobar si, partiendo de cero, se logra extraer un archivo alojado en el servidor a través de vulnerabilidades en la capa de base de datos.

Contexto
• El sitio se encuentra en producción, así que necesito que todas las acciones se realicen sin afectar su disponibilidad.
• Solo me interesa el vector que va desde la superficie pública de la aplicación web hasta la base de datos y, desde allí, la obtención del archivo objetivo.
• Las herramientas quedan a tu criterio —SQLmap, Burp Suite, Nmap u otras— siempre que el procedimiento sea ético y bien documentado.

Entregables clave
1. El archivo extraído (o, si no es posible, la evidencia técnica de por qué no puede obtenerse).
2. Informe técnico detallado que incluya metodología paso a paso, vulnerabilidades halladas, pruebas de concepto y recomendaciones de mitigación.
3. Resumen ejecutivo orientado a personas no técnicas.

Aceptación
Consideraré el trabajo concluido cuando reciba el archivo o la demostración de su exfiltración, junto con el informe y las recomendaciones. Si detectas hallazgos críticos adicionales, agradézco que los incluyas en el reporte.

Aclárame cualquier duda sobre el alcance antes de comenzar para evitar interferencias con operaciones del sitio.

Engagement Details

Contract Type: Contract (hourly or fixed; open to discussion)

Time Commitment: Part-time with potential to expand

Location: Remote or Chicago-based

I’m working on a master’s-level research paper in Computer Science, and the focus is firmly on Cybersecurity. My supervisor expects a publication-ready manuscript, so I need support that goes well beyond basic proofreading.

Here’s what I already have: a broad topic proposal, scattered notes from recent journals, and a rough outline. What I’m missing is the deep dive—consolidated literature review, a solid methodology section (quantitative or qualitative, whichever best suits the argument), coherent analysis, and perfectly formatted citations in IEEE style.

You’ll be free to recommend the most relevant sub-topics—anything from threat modeling and network security to encryption protocols or emerging attack vectors—so long as the final paper maintains an academic tone suitable for a postgraduate submission. I’m comfortable doing the final edit; what I really need is your rigorous research skill, clear technical writing, and familiarity with Cybersecurity frameworks and tools such as NIST, ISO/IEC 27001, Wireshark, Metasploit, or similar where relevant.

Acceptance criteria:
• Complete, 20 pages draft organised into Abstract, Introduction, Literature Review, Methodology, Results/Discussion, Conclusion, and References
• Minimum of 25 scholarly sources from 2019 onward
• Consistent IEEE in-text citations and reference list
• Plagiarism report showing originality above 90 %

Let me know your preferred timeline and how you’d approach structuring the research so we can get started right away.
