I need a Remote Access VPN set up on my Fortinet firewall so that staff can connect securely from outside the office using FortiClient. The connection will rely on simple password-only authentication—no tokens or certificates this time—so the job focuses on properly creating user accounts, assigning policies, and ensuring encryption settings follow Fortinet best practices. Here’s what I expect once you’re done: • A working FortiClient profile that users can import and connect with. • All necessary firewall objects, user groups, and security policies configured and saved. • Clear step-by-step documentation so I can duplicate the setup or make edits later. • A brief remote test session to confirm that the tunnel comes up, internal re...

I need a well-researched, publish-ready case study that examines how a technology company strengthened its overall network security by redesigning its firewall implementation. The goal is to show, step by step, what triggered the initiative, which design choices were made, how the solution was deployed, and what measurable results followed. Scope • Center the narrative on network security within a real or anonymized technology-sector setting. • Give special, in-depth attention to firewall architecture and rule-set hardening; intrusion detection systems or VPN references are welcome only where they help explain the firewall strategy. • Blend technical detail—vendor models, topology diagrams, configuration highlights—with business impact...

My AlmaLinux 8.10 server is running Plesk, Juggernaut Firewall, Apache, PHP-FPM, MariaDB and sits behind Cloudflare. After a recent DDoS wave I tightened the Juggernaut Firewall rules following AI-generated advice and, ever since, the main website only returns blank pages while every other hosted or backup domain works fine. Web pages are the only service failing; mail and databases stay responsive. I already restarted services and even rebooted the node, yet the symptom persists. I need an expert who routinely works with Plesk and Juggernaut Firewall to: • Dive into Apache, PHP-FPM and MariaDB logs to pinpoint the root cause of the blank-page delivery. • Audit the latest Juggernaut Firewall changes I applied and reverse or fine-tune anything that ...
