What Is a Man-in-the-Middle (MITM) Attack? How It Works and How to Prevent It
A plain-English explainer on man-in-the-middle attacks: what they are, how they work (ARP spoofing, rogue Wi-Fi, DNS spoofing, SSL stripping, adversary-in-the-middle phishing kits), the main attack classes, and the defenses that actually stop them — TLS and HSTS, certificate validation, VPNs on untrusted networks, phishing-resistant MFA, mutual TLS and DNSSEC.

Cryptography Explained: Symmetric, Asymmetric, Hashing and Where Each Is Used
A clear, defensive explainer of cryptography for security teams: what it is, symmetric encryption (AES) versus asymmetric encryption (RSA and ECC), hashing (SHA-256) and why it is not encryption, digital signatures, how key exchange works in a TLS handshake at a high level, why key management is the hard part, and a high-level note on post-quantum cryptography and NIST's standardized algorithms.
