Learn web development with step-by-step guides
From beginner to advanced — Django, Python, REST APIs, JavaScript, Bootstrap, and more
From the first alert through containment, eradication, forensics, and post-incident review — a structured playbook for handling web app breaches.
SSRF chains, deserialization, prototype pollution, CSPP, race conditions, and the subtle bugs that get past automated scanners. With Django-specific exploitation and defense.
A deep technical tour of the actual surface attackers probe in modern web apps — protocol quirks, header semantics, cookie behaviors, and the bugs they enable.
Who actually attacks web applications, what they're after, and the threat models that matter for SaaS, e-commerce, and B2B platforms in 2026.
Take your admin, database and internal tooling off the public internet entirely: WireGuard peers and keys, binding services to the tunnel, restricting Django admin by network, revoking access, the MTU trap, and what a VPN does not solve.
Run your own S3-compatible storage without fooling yourself about durability: bucket policies and least privilege, presigned URLs, direct browser uploads, why a single node is not a backup, mirroring, lifecycle rules, and when a managed provider wins.
Run several Django applications on a single machine without them taking each other down: label-driven routing, automatic certificates, network and resource isolation, independent deploys, per-app backups, and knowing when one server is no longer enough.
Where secrets leak in a Django deployment and what to do about it: file permissions, environment variables versus files, build arguments baked into image layers, git history you cannot really erase, encrypted-at-rest storage, and a rotation process.
Sending mail is easy; arriving is not. Authentication records explained properly, the alignment rule most guides omit, why fresh servers cannot send, asynchronous delivery, bounce handling, and the headers that keep you out of the spam folder.
DNS treated as the distributed system it is: which records matter, what TTL really controls, why propagation is the wrong word, negative caching, CAA to restrict certificate issuance, and how to move a domain without a gap in service.
Certificates from the inside out: what the chain actually proves, HTTP-01 versus DNS-01, renewals that stop silently, rate limits, HSTS as a one-way door, and how to read the error messages that send everyone in the wrong direction.
Everything a Django deployment needs to survive losing a server: consistent database dumps, media and secrets, encrypted offsite copies with restic, retention that survives ransomware, point-in-time recovery, and the restore drill nobody runs.
Lock down a Django server properly: default-deny firewall rules, key-only SSH without locking yourself out, fail2ban that actually bans, IPv6 rules people forget, and why Docker quietly publishes ports straight past your firewall.
A complete playbook for moving a running Django site to a new server: inventory, runtime parity, database and media transfer, certificates before DNS, the delta-sync window, the IPv6 trap that breaks TLS issuance, and how to keep a working fallback.
Find your breaking point before your users do: designing realistic load scenarios, driving them with Locust or k6, reading the latency percentiles that matter, locating the true bottleneck, and turning results into capacity plans and autoscaling signals.
Escape fat views and fat models with a pragmatic clean architecture for Django: a service layer for business operations, selectors for reads, clear domain/framework boundaries, transactions and validation in the right place, and business logic you can test without a request.
