## AppSec & APIs

Securing applications, APIs, webhooks, secrets and the software supply chain, from code review to CI pipelines.

- [The Vulnerability Backlog That Never Shrinks](https://firewallsync.com/posts/the-vulnerability-backlog-that-never-shrinks/index.md): Vulnerability management backlogs keep growing because most programs prioritize by CVSS score alone. A better way to triage what actually gets fixed. (2026-10-01)
- [Dependency Audits Without Slowing Down Releases](https://firewallsync.com/posts/dependency-audits-without-slowing-down-releases/index.md): Software supply chain security doesn't require reviewing every dependency manually. A tiered audit approach that keeps release velocity intact. (2026-09-29)
- [Container Image Scanning: What CI Pipelines Still Miss](https://firewallsync.com/posts/container-image-scanning-what-ci-pipelines-still-miss/index.md): Container image scanning in CI catches CVEs but misses config drift and runtime secrets. Here's what to add to close the gap. (2026-09-28)
- [The API Key Mistakes That Keep Making Breach Reports](https://firewallsync.com/posts/the-api-key-mistakes-that-keep-making-breach-reports/index.md): Why leaked API keys keep showing up in breach reports despite better secrets scanning, and the three preventable mistakes behind most of them. (2026-08-24)

## Identity & Access

Authentication, MFA, passkeys, session security and least-privilege access for people and machines.

- [MFA Fatigue Attacks: What Actually Stops Them](https://firewallsync.com/posts/mfa-fatigue-attacks-what-actually-stops-them/index.md): MFA fatigue attacks exploit push notifications, not passwords. Here's why number matching and phishing-resistant MFA actually stop them. (2026-09-25)
- [Least-Privilege Access Controls That Don't Slow Teams Down](https://firewallsync.com/posts/least-privilege-access-controls-that-dont-slow-teams-down/index.md): How to roll out least-privilege access without slowing engineers down: start from real usage data, phase the rollout, and make access requests fast enough that nobody routes around them. (2026-08-01)

## Security Operations

Incident response, logging, alerting, backups and the processes that keep security work from stalling.

- [Security Champions Programs That Don't Fizzle Out](https://firewallsync.com/posts/security-champions-programs-that-dont-fizzle-out/index.md): Security champions programs usually fail within two quarters for the same predictable reasons. What to structure differently from the start. (2026-10-02)
- [Logging for Incidents, Not for Dashboards](https://firewallsync.com/posts/logging-for-incidents-not-for-dashboards/index.md): Security logging best practices for incident response differ from logging for dashboards. What to capture so you can actually reconstruct an incident. (2026-09-30)
- [The Tabletop Exercise Gap: Testing Incident Response for Real](https://firewallsync.com/posts/the-tabletop-exercise-gap-testing-incident-response-for-real/index.md): Most incident response tabletop exercises test whether people know the plan, not whether the plan survives contact with a real incident. Here's the fix. (2026-09-27)
- [Alert Fatigue Is a Security Metric, Not a Morale Problem](https://firewallsync.com/posts/alert-fatigue-is-a-security-metric-not-a-morale-problem/index.md): Alert fatigue in security operations isn't a staffing problem — it's a signal your detection tuning has failed. Here's how to measure and fix it. (2026-09-26)
- [Why Your Incident Postmortems Aren't Preventing Repeats](https://firewallsync.com/posts/why-your-incident-postmortems-arent-preventing-repeats/index.md): Why blameless postmortems often fail to prevent repeat incidents, and how to make action items stick so the same failure does not happen twice. (2026-08-12)

## Fundamentals

Plain-English explanations of the core ideas behind security decisions: encryption, the CIA triad, zero-days and more.

- [Symmetric vs Asymmetric Encryption: When to Use Each](https://firewallsync.com/posts/symmetric-vs-asymmetric-encryption-when-to-use-each/index.md): Symmetric vs asymmetric encryption explained: how each actually works, why they're almost always used together in practice, and where each one fits.
