I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...

I need a capable network engineer who can spend a full working day at my client’s premises acting as our hands-on field resource while my remote team carries out all configuration tasks. Your focus will be purely physical: rack-mounting the servers, switches, and firewalls; dressing and labeling power and Ethernet runs; attaching console and management leads; then powering everything up so we can reach it remotely. Once each device is live you’ll run quick sanity checks—simple pings, basic connectivity, and a printer test—to confirm the build is progressing as planned. Desktops and laptops must join the network without issue, and at least one printer needs to produce a clean test page before you leave. I’ll supply a clear step-by-step build guide and remain ...

I have already completed the full implementation of my anomaly-detection model for network traffic and gathered all experimental results; what I still need is a polished, publication-ready research paper that turns this technical work into a clear, compelling narrative. The target length is 15–20 pages, formatted according to the IEEE citation style. Because I have not locked down a specific outline, I’d like you to recommend the ideal academic structure—something along the lines of abstract, introduction, related work, methodology, results, discussion, and conclusion—and then flesh it out after we agree. I will supply you with the code, datasets, graphs, and raw result tables so you can focus on literature integration, critical analysis, and crisp technical writing...

I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...

My network edge relies on a Sophos XG appliance and a Fortinet FortiGate unit. Both devices are in production, but their current configuration is a mix of legacy rules and quick fixes that now interfere with performance and security. I want a seasoned firewall engineer to step in, examine every setting, correct what is wrong, and design a clean, least-privilege rule base. Scope of work • Configuration – back up the existing setups, remove or refine redundant rules, and align all interfaces, NAT, VPN, IPS and logging options with best-practice guidelines for Sophos SFOS and FortiOS. • Troubleshooting – identify and eliminate the intermittent drops we see on site-to-site VPN and outbound web traffic. Validation must include live traffic tests and log review. &bul...

I operate a cluster of Windows Server 2019 machines and need an experienced set of hands to keep everything running smoothly. Your focus will be three-fold: maintaining the servers themselves, getting our Veeam Backup & Replication environment dialled-in, and stepping in whenever a network hiccup or whitelist request appears. On the Veeam side I already have repositories in place; what’s missing is a clean, reliable backup configuration and the regular monitoring that guarantees every job finishes without warning bells. Restoration testing and documented recovery steps will be part of the routine so we can prove our RPO/RTO targets at any moment. Networking support centres on troubleshooting issues as they arise and processing whitelist updates for partners and applications tha...

I run a Canadian real-estate search engine that must stay lightning-fast for genuine home-hunters while remaining fully crawlable by Google, Bing and other reputable AI/search bots. Right now Cloudflare shows ±100 k daily hits from malicious, spam and scraper bots; that traffic spikes the servers, ruins bounce-rate metrics and occasionally knocks the site offline. I have already: • Placed the site on Cloudflare, • Allowed full, captcha-free access for visitors inside Canada, • Forced most other countries through a captcha, • Experimented with firewall rules, IP and UA blocking. Unfortunately, Google’s crawler activity drops whenever the shield becomes too strict, so I’m looking for an expert who can strike the sweet spot: block malicious...

My web application is ready to go; what’s missing is a clean, reliable deployment on AWS. I want the site running on standard-configured EC2 instances—no special hardware or exotic AMIs—inside a secure VPC.

My QRadar deployment needs a sharper eye on phishing. I want a set of custom Alert and Correlation rules that reliably pick up everything from the first suspicious e-mail event to follow-up user activity that hints the attack is moving forward. Scope • Build correlation logic that ties together indicators such as mail-gateway detections, odd mailbox rules, risky web clicks, and any subsequent authentication anomalies. • Create alert rules that trigger actionable offenses the moment a phishing pattern emerges. The rules must fit neatly into existing QRadar best practices: use building blocks where appropriate, keep AQL searches efficient, and document each rule so another analyst can tune or extend it later. Acceptance A rule set that fires during lab replay of know...

I need a concise, CPTS-style penetration test focused on network infrastructure. You will receive a shortlist of public-facing domains plus several internal subnets that I want examined end-to-end. The engagement should mirror a real-world attack path: reconnaissance, exploitation, limited post-exploitation, and clear documentation of every step. Scope • Targets: the domains I provide and the connected internal network segments. • Methodology: full penetration testing, not just a vulnerability scan. Feel free to mix automated tools (nmap, Nessus, OpenVAS, Metasploit, BloodHound) with manual techniques. • Duration: this is a quick assessment, so I expect focused work rather than an open-ended engagement. Deliverables 1. Executive summary highlighting business impact in ...

My Panasonic Ns500 PBX sits on but cannot “see” the rest of my network. Everything else flows through a FortiGate 60F firewall, a FortiSwitch 424E-Fiber core, and a FortiSwitch 124F-FPOE at the edge. I need someone to shape the network so this Panasonic box can handle VoIP communication smoothly. What I already know • The PBX will run pure SIP. • Dedicated VoIP rules on the FortiGate are required; simple, generic access is not enough. What I need from you • Review the current FortiGate policy set, VLAN layout, and switch port profiles. • Create or adjust firewall rules, NAT, and any SIP ALG or helper settings so that SIP registration, signalling, and RTP streams pass without one-way audio or dropped calls. • Tag or untag the appropriate swi...

I need to obtain hard-to-reach details—specifically the IP address, associated phone number, and any location-related information—linked to one particular Telegram account. Standard OSINT searches have already been exhausted, so I’m explicitly open to advanced, purely technical hacking techniques that dig directly into Telegram traffic or MTProto behaviour. If this is within your skill set, tell me how you would approach the task, which tools or exploits you prefer to leverage, and what minimal input you require from my side (e.g., username, recent message, session file). Deliverables • Verified current or last-seen IP address for the target account • Recovered phone number (or clear statement if technically impossible) • Any additional address or geo...

I need a custom-built screen-sharing application for Windows that feels as seamless as TeamViewer or AnyDesk but remains persistent even if the host user tries to remove or disable it. The service must install itself as a background process, automatically launch at every system start-up, and quietly reconnect without any manual action. Core capabilities I expect • Full remote-control of the host PC, including keyboard and mouse input, with smooth, real-time streaming. • Secure file transfer in both directions. • Single sign-on authentication so my team can log in with our existing identity provider rather than juggling extra passwords.

My security cameras stopped showing live video and recorded footage on the monitoring app. The wiring and power seem fine, so I’m convinced the problem sits on the software side—likely a mis-configuration or corrupted firmware. I need someone who can jump in quickly, diagnose the software fault, and get every camera streaming and recording again without wiping my existing footage or settings. You should be comfortable with typical NVR/DVR interfaces, remote desktop tools, and updating or rolling back firmware when necessary. Once the feeds are restored, I’d like a short explanation of what went wrong and the steps you took so I can avoid the same outage in future.

I run a production-level Windows server that now needs steady, professional care.
