I am preparing for the CompTIA Security+ certification and want targeted, exam-style tutoring that zeroes in on Network Security—specifically firewalls and VPNs. The goal is to master the current exam objectives, clear up any conceptual gaps, and build enough confidence to score well on test day. Sessions should be live, interactive, and paced to my schedule. I learn best when theory is tied directly to hands-on examples, so walking through real-world firewall rules, VPN configurations, and related packet-flow scenarios is essential. Explanations must stay aligned with the Security+ wording and depth so I recognize the phrasing when it appears on the exam. Deliverables: • A structured lesson plan broken into manageable milestones • Live tutoring sessions with screen-sha...

ALFA NETWORKS ADAPTOR OR SIMILAR IS A REQUIREMENT I need a cyber sec expert who already owns an Alfa Networks USB adapter (or a comparable injection-capable card) to carry out a controlled WiFi-based denial-of-service exercise. The goal is to you use the Kali Live boot with persistence USB stick, and the Alfa Networks adaptor, to launch a Denial-of-Service attack on your own mobile phone (or smart TV etc) in order to prevent it accessing your home WiFi. its just a simulation so we only need 4 screenshots. I ordered my alfa networks adaptor but it got delayed with the shipment so now need help if you own one. ALFA NETWORKS ADAPTOR OR SIMILAR IS A REQUIREMENT

This project covers the end-to-end creation of a brand-new Local Area Network for our premises. The environment will serve daily operations for both computers and servers as well as our shared printers and scanners, so stability, speed, and clean segmentation matter. The scope begins with planning: assessing the floor layout, sizing the switch stack, deciding on cable runs, and selecting hardware that fits future growth. Layer-2 and Layer-3 configuration must follow best practices—think VLAN separation for user groups, QoS where printing traffic needs it, and a security baseline that shuts unused ports, enforces 802.1X, and applies sensible ACLs at the edge. During implementation, I expect neat rack work, labelled cabling, and documented configurations (Cisco-style CLI or equivalen...

I have several Cisco-based lab and production environments that need hands-on attention from someone who already feels at home with CCNA-level work. Over the next few weeks I’ll be refining network configuration, tightening security, and—most importantly—sorting out a few stubborn routing-protocol issues that keep popping up. Here’s the situation: • Network configuration needs polishing on a mix of Catalyst switches and ISR routers, including VLAN planning, trunking, and interface tuning. • Day-to-day troubleshooting consumes far too much time; I want clear root-cause analysis when links flap, routes disappear, or access lists misbehave. • Security hardening is overdue—standard ACLs are in place, but I need smarter filtering and a quick r...

I need help installing routers for a series of small communication-network rollouts. Each day’s route will be planned in advance, and the actual on-site work rarely exceeds one to two hours. Your role is straightforward: pick up the assigned router, travel to the client location, mount the unit, connect it to the existing cabling, confirm internet connectivity, then send me a quick photo and speed-test screenshot before leaving. The schedule is flexible as long as the job is finished on the agreed day; I issue payment weekly, starting at 25 000 ₽, and increase it for consistently smooth, on-time work. What matters most to me is punctuality—I’d rather reschedule than keep a client waiting—and complete honesty about any delays or technical issues you encounter. Basi...

This project centres on a clean rack-and-stack of new IT gear in our data room. I will supply detailed rack elevations and network diagrams beforehand; once you arrive, the job is entirely hands-on: • Mount the servers, switches, firewalls and routers in the designated cabinets. • Dress and terminate all power and data cabling, keeping airflow and service-loops in mind. • Attach and label console leads so my remote team can reach each device immediately. • Power-on, verify link lights, and run basic connectivity checks, noting any issues that need escalation. A short completion report—photos of the finished racks, cable test results and a summary of any troubleshooting performed—will close out the engagement. You’ll work in...
