security trained

The learned layer of the security guru: name the asset, the trust boundary, the attacker action, and the observable impact before calling anything a finding.

mental model

Define the owned asset, trust boundary, attacker action, and observable impact. A scanner match starts an investigation; a finding needs a reachable path and evidence. Map confirmed web application risks to the current OWASP Top 10:2025. Public-source intelligence has a separate subject, purpose, and source-quality boundary.

examples

For a bounded repository secret sweep, list matching file names only; inspect the smallest relevant context privately and redact any actual value:

rg -l --hidden -g '!node_modules' -g '!dist' -g '!.git' \
'BEGIN (RSA|EC|OPENSSH) PRIVATE KEY|AKIA[0-9A-Z]{16}' .

This is a lead-finding pattern, not a complete secret scanner. The local ripgrep 15.2.0 probe matched a synthetic apiKey = "placeholder" line, which demonstrates why text matches alone cannot establish a leak.

best practices

  • Trace input to privileged sink and identify the missing control before calling a code pattern exploitable. For SQL, bind data as parameters rather than concatenating it into query text (OWASP SQL injection prevention).
  • Match dependency audits to the repository's package manager and lockfile; report tool failure as a coverage gap, never as zero vulnerabilities.
  • Keep discovered credentials out of reports and logs; name the file and affected service, then recommend revocation or rotation through its owner.
  • For OSINT, distinguish direct primary evidence, corroboration, inference, and conflicting claims. Do not turn public availability into permission for broad personal profiling or active probing.

strengths

The quick scan is efficient for narrow pre-release checks; STRIDE helps identify missing trust-boundary controls; CTI can verify external exposure when the subject and purpose are explicit.

weaknesses / pain points

Static scanning misses runtime authorization and produces false positives. Threat models cannot prove exploitability without a real path. CTI sources can be stale, copied from one another, or incorrectly linked to a person.

gotchas

  • Bundled source material may describe command syntax or broad investigative pivots that the guides here do not endorse. The guru's entrypoints govern the actual workflow, and current task authority governs scope, installs, exports, and commits.
  • A pattern match has no severity by itself; do not carry upstream sample severities into a real report without an attack path.

known bugs

No version-specific tool defect has been reproduced here. Record a bug only with its affected version, upstream issue, and observed workaround.

practiced cases

  • A local probe with ripgrep 15.2.0 returned the synthetic apiKey = "placeholder" line, exercising the false-positive workflow end to end. No real application attack path or release audit has been run through this page.

sources and lineage

This page draws on three guides: security-scan for bounded sweeps, ck-security for threat modeling and fixes, and cti-expert for public-source intelligence. The rules above resolve their different authority and evidence assumptions.
