I’m looking for an extra pair of expert hands to keep several integrated security environments running smoothly. Day to day you will dip into CCTV/NVR platforms, Genetec-based VMS, Windows workstations and servers, access control panels, and the supporting LAN. When something misbehaves I’ll count on you to isolate the fault, correct it, and record exactly what was done so the fix is repeatable. Beyond urgent tickets, I also need periodic system reviews: checking firmware levels, validating camera coverage, confirming storage retention, spotting bandwidth bottlenecks, and flagging any compliance gaps. The insights you gather should flow into clear Excel reports, updated SOPs, and other technical documentation that management can act on. If you apply, highlight the depth of yo...

I have a complete code-base that now needs to live on a cloud server. The immediate goal is twofold: 1) install and configure the application so it runs reliably in the cloud environment I provide, and 2) comb through every file, dependency, and configuration to confirm there are no hidden backdoors, malicious packages, or insecure default settings left behind after development. I’m deploying to a cloud server (provider is flexible, so please be comfortable with AWS, Azure, or GCP). You’ll set up the runtime stack, handle environment variables, connect the database, and push the first production build. While doing so, perform a thorough security audit: manual inspection, automated scanners, and any static-code-analysis tools you trust. If something suspicious appears, docu...

I’m running an Exchange hybrid setup (Exchange Online with an on-prem 2019 mailbox server) and messages sent from the cloud aren’t reaching mailboxes on-premises. Mail flow the other way around is fine, so the fault lies somewhere in the cloud-to-on-premises path. I’ve already pulled message traces and transport logs; they show several repeated errors but I’d like a fresh set of eyes to confirm the root cause, validate the current Hybrid Configuration Wizard settings, and correct whatever is blocking delivery.

My site has suddenly stopped loading and I’m pretty sure it’s a DNS-related problem. I haven’t knowingly made any recent changes, though I’m not 100 % certain. The good news is that I can log into the hosting control panel, so you’ll have full access to DNS zones, nameserver settings, and any server logs you might need. I have a rough idea of how the records should look, but I’m not confident enough to troubleshoot this myself. Here’s what I need from you: • Inspect the current nameserver and DNS record configuration (A, CNAME, MX, AAAA, etc.). • Identify and correct any mis-pointed or missing records so the domain resolves properly worldwide. • Confirm propagation and show that the site loads over both HTTP and HTTPS from multi...

I’m refreshing our on-premises network and want it configured and stress-tested by someone who lives and breathes both infrastructure and security. First, the infrastructure work: • Build out the Layer-2 and Layer-3 design—router and switch configuration, IP addressing, VLAN segmentation, and DHCP where required. • Ensure the new topology is clean and resilient, with clear change notes so I can reproduce or roll back any step. • Troubleshoot anything that crops up during the cut-over and document the fixes. Once the cables are tidy and the configs committed, I’ll need you to put on the black hat—legally, of course. Using tools such as Nmap, Nessus, Kali Linux, or your preferred equivalents, perform network scanning, a full vulnerability assessment, ...
