A comprehensive guide to optimizing cloud expenditure on the Vercel platform. It details how to understand the Fluid Compute pricing model, identify key cost drivers (such as function execution time, bandwidth, and middleware invocations), and implement best practices like edge caching, memory right-sizing, and aggressive asset caching. Use this when analyzing high Vercel billing, implementing cost controls, or managing a SaaS budget.

A comprehensive guide to simulating Man-in-the-Middle (MITM) attacks using industry-standard tools like Bettercap, Ettercap, and mitmproxy. This technique is strictly for authorized penetration testing environments to assess cryptographic controls, validate TLS certificate pinning, and test network defense mechanisms against ARP/DNS spoofing and sniffing.

This skill simulates Man-in-the-Middle (MitM) attacks and ARP cache poisoning using advanced tools like Ettercap and Scapy. It is designed exclusively for authorized, controlled lab environments or penetration tests. Use cases include validating the efficacy of Dynamic ARP Inspection (DAI), assessing port security mechanisms, and testing whether IDS/IPS or SIEM systems detect Layer 2 spoofing attempts.

This skill covers the technical process of setting up SSL/TLS inspection (decryption) on next-generation firewalls and proxies. It details how to act as a trusted Man-in-the-Middle to intercept, decrypt, and inspect encrypted HTTPS traffic for malicious payloads, data exfiltration, and policy violations. The workflow includes generating internal Certificate Authority (CA) certificates and deploying them across various operating systems (Windows, macOS, Linux) to ensure visibility into the web's encrypted blind spot.
