APPLICATION MATERIALS / DEFENSIVE SECURITY

Security work.
Ready for a closer look.

Two role-focused résumé drafts use my supplied October 2026 résumé, including the correct education, Security Officer experience, and source-linked technical projects. For a third focus—Security Automation & Engineering—use the evidence-based engineering path; it is not a separate résumé or an employment claim.

The new printable résumés are designed for a clear one-page application and browser PDF export. Plain-text copies remain available for editing. All formats retain Don Lopez branding, omit the private phone number, and distinguish résumé-reported experience from public training-lab evidence.

TRACK 01 / MONITORING & TRIAGE

SOC Analyst

Prioritizes investigating authentication findings, Windows process telemetry and network behavior.

  • Recorded AD investigation: host, session and packet correlation
  • Splunk Enterprise SPL: 3/5 boundary failure corrected to 5/5
  • Windows and network triage with explicit evidence limits
TRACK 02 / ASSESSMENT & VALIDATION

Security Analyst

Prioritizes repeatable assessment, remediation verification and contextual detection analysis.

  • Four deliberate localhost HTTP findings reduced to zero
  • Splunk detection debugging with a saved dashboard
  • Recorded AD telemetry analysis with reproducible Python checks

RÉSUMÉ DATA / SOURCE SCOPE

Additional lab and tooling experience

My supplied résumé lists Sigma/Snort rule practice, Wireshark, Nessus, Nmap, Linux, VMware, Docker, and AWS basics. It also reports expanded training outcomes; those source artifacts are separate from the published capture analysis and controlled labs, so the numerical results are not represented here as independently verified. Read the source distinctions ↗.

INTERVIEW / TESTED STORIES

Inside the investigation

What connects the Active Directory activity across hosts?

Same-host parent process GUIDs and logon sessions link remote PowerShell to its host context; matching TCP tuples and timing add network corroboration. A 39.812-second collection delay changes apparent ordering. This is independent analysis of OTRF’s recorded emulation, not an owner-operated capture or production incident. The Python analysis ran; its SPL/Sigma translations remain unexecuted. Inspect the source-linked case ↗

Why did the original Splunk search miss two findings?

Both omitted cases depended on failures exactly 600 seconds before a success. The original streamstats time_window=10m query returned 3/5; the bounded replacement explicitly counted ages 0 through 600 seconds inclusive and the saved Splunk dashboard displayed 5/5 expected synthetic results. Review the discrepancy ↗

Would the five findings justify declaring an incident?

No. These are synthetic authentication events. Even with genuine operational events, confirm source integrity, MFA/session telemetry, account context, potential benign activity, and escalation authority before classifying compromise.

Does four-to-zero mean the web application was secured?

No. Four deliberately introduced rule violations stopped matching the localhost fixture after the changes. Browser enforcement, TLS, real application workflows and independent penetration testing were not established. Read the scope ↗

SUBMISSION READINESS

Application details

Contact information, experience scope, and credential verification are documented below.

02 / EXPERIENCE

Work history

My supplied résumé lists Allied Universal Security Officer experience (2019–present): monitoring, incident reports and escalation. The public capture analysis and controlled labs are independent technical projects, not SOC employment.

03 / CREDENTIALS

Certification verification

Security+ and CySA+ (earned October 2026 according to my résumé) are holder-reported; issuer verification links remain pending. Splunk SCCDA is planned, not earned. See how to share issuer-backed verification, including whether the badge displays your legal name, before making it public.

About these materials

The AD investigation analyzes OTRF’s public recorded emulation telemetry. Other reproducible exercises use synthetic, generated or localhost inputs. The Splunk screenshot records a genuine application result on that training data. Project work, employment history, and credential verification have distinct scopes; the linked case studies explain the evidence for each result.
