I need GenieACS installed, secured, and fully tuned to manage Airtel Xstream routers in production. The deployment must let me: • Register and remotely manage devices • Push firmware upgrades without manual intervention • Monitor performance metrics in real time • Apply custom IP pools, VLAN tagging, and QoS rules directly from the ACS interface You are free to choose the operating system and database you are most comfortable with; just document every step clearly so I can reproduce it on another machine. A clean web UI, working API calls, and successful provisioning of at least one Airtel Xstream unit will serve as acceptance criteria. Cloud or on-prem hosting is fine as long as latency remains low and security best practices (TLS, strong credentials, firewa...

I run my workload on a single Compute Engine instance and I’m urgently looking to tighten security after a recent unauthorized-access event. The immediate priorities are: • Lock down the instance: review and update firewall rules, service accounts, IAM roles, OS-level settings, and any exposed ports. I expect clear recommendations (e.g., Cloud Armor policies, VPC Firewall tweaks, OS patching) and implementation where feasible. • Trace the breach: pull the relevant Cloud Logging records, VPC flow logs, and any SSH / RDP audit data to build a timeline showing when the intrusion occurred, the source IPs, and actions performed. Deliver the raw export plus a concise report so I can hand it to management. • Prevent recurrence: enable or improve ongoing monitoring—Se...

Senior Zscaler engineer needed to guide me over the shoulder while I rebuild the foundational pieces of our ZPA/ZIA setup. I drive the consoles; you advise in real time and explain the why behind each setting. Context: A current implementation works but isn't scalable, security-focused, or aligned with best practice. Goal is to reset the foundation so those problems don't carry forward, built to a strong security bar, with a structure that scales cleanly across employees, contractors, admins, and third parties without rework. Constraint: Okta SSO is operational and out of scope. ZIdentity group/role binding is on a separate track. Work fits around both. In scope: - Hardened pre-auth machine tunnel with the strongest realistic device trust model - Least-privilege pre-logon acc...
