What was set up, and what the evidence shows

Each environment had a specific purpose and boundary; these are not presented as one connected enterprise SOC.

01 · SIEM investigation

Case closed

Windows Security, System, Application and PowerShell logs forwarded to Splunk Enterprise on Ubuntu over TCP 9997. Investigated five Event ID 4625 failures from loopback against a local test account; SOC-001 was closed as controlled activity.

// about

Defender mindset. Engineer's toolkit.

I’m Ranbir Mishra, an MCA graduate focused on SOC analysis and cybersecurity. I turn hands-on lab evidence into careful investigations, clear reports and practical next steps.

SOC · SIEM · Endpoint · Network

I follow the evidence—not the assumption.

I’ve built a Splunk lab to examine Windows authentication events, investigated case SOC-001 through to a documented benign closure, and deployed both LimaCharlie endpoint monitoring and a Cowrie SSH honeypot in controlled virtual labs.

My work also includes Wireshark traffic analysis and scoped testing of a self-hosted DVWA application. I document what I observed, what I could not confirm, and what I would validate next—so a project report is useful to someone reviewing the evidence, not just a list of tools.

// what I bring

How I can add value to your team

Practical capabilities from lab work, each tied to something I've actually built and documented.

📡

Security Monitoring & Alert Triage

Tier-1 triage across Windows and Linux telemetry: review alert context, separate true positives from benign noise, escalate with evidence. Experience analysing failed logons (4625): account, source, logon type and status codes.

🧪

Detection Engineering

Writing SPL threshold searches for repeated failed logons and designing LimaCharlie rules for PowerShell, process chains, scheduled-task persistence and process-to-network activity, with false-positive tuning in mind.

🔬

Incident Investigation & Reporting

Investigations that run from detection to analysis, validation and a closed case, with MITRE ATT&CK mapping, evidence tables and honest outcomes — including closing a case as benign when that is what the evidence shows.

🕸️

Vulnerability Assessment (VAPT)

Scanning and manual validation with Nessus, OpenVAS, Nikto, ZAP and Burp Suite; OWASP Top 10 testing; CVSS-rated findings with PoC and step-by-step fixes.

🐧

Linux Administration & Hardening

User and permission management, sudoers, services and processes, log review with journalctl/syslog, and Bash + Cron automation for routine tasks.

🧱

Full-Stack Development

MERN applications with JWT auth and REST APIs — useful for security tooling, internal dashboards and understanding how applications are attacked and defended.

Demonstrated work & next validation

Clear status labels matter in security: completed activity, detection design, and validated detection outcomes are not interchangeable.

Applied in documented labs

  • Configured a Splunk log-collection workflow and analyzed controlled Windows authentication events.
  • Deployed Cowrie and summarized one isolated SSH test session using its text and JSON evidence.
  • Analyzed controlled network traffic and assessed a self-hosted, intentionally vulnerable DVWA target.
  • Enrolled a Windows lab endpoint in LimaCharlie and performed benign scheduled-task activity.

Designed or awaiting validation

  • The LimaCharlie report records 0 of 13 detection rules tested; successful custom-rule alerts are not yet evidenced.
  • The Cowrie exercise was author-generated in an isolated lab, not a capture of live public attackers.
  • Production SOC operations, real-world incident response, and a real host compromise are not claimed.
  • Next step: test detections with safe, repeatable activity and preserve the alert, event, and triage evidence.

Featured security projects

Six practical security projects spanning SIEM, AI-assisted analysis, endpoint detection, network defense, honeypot monitoring and application security. Each summary distinguishes documented capabilities from results still to validate.

AI-assisted SOC · log analysis

AI-Powered SOC Analyst Platform – Automated Security Log Analysis & Incident Investigation

  • Developed a Flask-based platform to analyze uploaded authentication logs and identify suspicious login patterns and brute-force activity.
  • Implemented IOC extraction, rule-based threat classification and MITRE ATT&CK mapping to support structured investigation.
  • Integrated Ollama with Llama 3.2 for AI-assisted incident analysis, alongside a REST API and SQLite-backed incident management.
  • Generated downloadable investigation reports to support analysis and documentation; AI findings support analyst review rather than replace it.
Read detailed project notes

Objective: make authentication-log review more structured by bringing suspicious-pattern detection, indicator extraction, investigation context, incident records, and report generation into one platform.

Approach: Flask provides the application layer; rule-based classification identifies candidate activity, while Ollama with Llama 3.2 adds analyst-assistance. SQLite stores incident-management data, and REST API functionality supports programmatic access.

Analyst value: findings and ATT&CK context are organized for review, with downloadable reports to support documentation and handoff.

Validation boundary: the portfolio describes implemented capabilities, not measured detection accuracy, production deployment, autonomous response, or a benchmark result.

SSH honeypot · Cowrie 3.1.1

Cowrie SSH Honeypot: Session Monitoring & Log Analysis

  • Deployed Cowrie on an Ubuntu VM and used a Kali VM as an authorized test client inside an isolated VMware lab; SSH listening on TCP 2222.
  • Correlated Cowrie text and JSON events into one recorded session: one accepted test login and five shell-command events (whoami, hostname, uname -a, pwd and exit).
  • Summarized authentication, source, session and command evidence with shell tools and Python, then mapped only supported behavior to MITRE ATT&CK (including T1021.004, T1033 and T1082).
  • Evidence limits: the test produced zero failed logins, so no brute-force detection is claimed. Cowrie's shell is emulated; the commands did not execute on the Ubuntu host, and the activity was generated by the author—not a real attacker.
Read detailed project notes

Objective: study how an SSH honeypot records connection and session behavior, then turn its raw logs into a coherent analyst summary.

Environment: Cowrie 3.1.1 ran on an Ubuntu VM. A Kali VM made one authorized test connection to TCP 2222 inside the isolated VMware lab.

Analysis: text and JSON events were correlated by session, then reviewed for authentication, source, and command context. Five emulated shell commands were recorded and mapped only where the observed behavior supported the mapping.

Observed result: one accepted test login, five commands, and zero failed logins. This is a session-analysis exercise, not evidence of live attacker activity or credential guessing.

Important limitation: Cowrie presents an emulated shell. The commands did not run on the Ubuntu host; no host compromise or automated alert is claimed.

SIEM · Splunk

SIEM-Based SOC Monitoring, Threat Detection & Incident Investigation

  • Deployed Splunk Enterprise 10.4.3 on an Ubuntu VM and a Windows 10 Universal Forwarder, sending events over TCP 9997 to a dedicated index.
  • Collected Windows Security, System, Application and PowerShell Operational logs; the report records 1,767 ingested events.
  • Built a threshold search for repeated Event ID 4625 failures and investigated five local test failures in case SOC-001, closed as controlled test activity.
  • Recovered from a forwarder outage after the server address changed. The report records dashboard panel evidence, but does not establish a complete six-panel dashboard or a captured alert firing.
Read detailed project notes

Objective: build a small SIEM workflow that collects Windows events, supports a repeatable authentication search, and records the analyst's decision for a candidate alert.

Data path: Windows 10 logs were sent by Splunk Universal Forwarder to Splunk Enterprise 10.4.3 on Ubuntu over TCP 9997 into a dedicated index. Collected sources included Security, System, Application, and PowerShell Operational logs.

Investigation: a threshold search grouped Event ID 4625 failures by source and account. Five failures from loopback against a local test account were examined in SOC-001 and closed as controlled activity; compromise was not observed.

Operational lesson: changing the server address interrupted forwarding. Recovery reinforced the need for stable destination configuration and checking the correct Windows event channel during investigation.

Evidence boundary: 1,767 ingested events are documented. The available report does not establish a saved alert firing or a completed six-panel dashboard.

EDR · MITRE ATT&CK · Rule design

Windows EDR Threat Detection & Incident Response with LimaCharlie

  • Enrolled a Windows 10 Pro VM in LimaCharlie and documented endpoint baselining and detection-rule configuration.
  • Planned rules cover PowerShell execution, a cmd.exe → PowerShell chain, scheduled-task creation and process-to-network activity.
  • Created, checked and removed a benign scheduled task (MITRE ATT&CK T1053.005); this demonstrates the test activity, not a successful detection.
  • The report explicitly records 0 of 13 rules tested and shows no custom rule firing or investigated alert. Detection validation remains in progress.
Read detailed project notes

Objective: establish endpoint visibility and document detection-and-response scenarios for common Windows activity patterns.

Work completed: a Windows 10 Pro VM was enrolled in LimaCharlie and baselined. Rule scenarios were documented for PowerShell, a cmd.exe-to-PowerShell chain, scheduled-task creation, and process-to-network activity.

Controlled exercise: a benign scheduled task was created, checked, and removed. This confirms the test action only; an alert or detection was not observed in the available evidence.

Current status: the report states 0 of 13 rules tested. Rule efficacy, custom-rule alerting, and incident-response outcomes remain unvalidated.

Next validation: run one safe scenario at a time and preserve the source event, matching rule, alert, and analyst disposition before making an effectiveness claim.

Network Security

Network Security Monitoring, Packet Forensics & Traffic Analysis

  • Ran Nmap discovery against a lab target and examined the resulting traffic in Wireshark.
  • Captured a full-range SYN scan producing approximately 65,000 SYN packets, plus a separate controlled test of ten SYN probes.
  • Documented five suspicious traffic patterns, including reconnaissance (MITRE ATT&CK T1046), then assessed them in the isolated lab context.
  • This was controlled traffic analysis: the report does not claim exploitation, data access or a real-world compromise.
Read detailed project notes

Objective: practice moving from network discovery to packet-level review, and describe traffic in context rather than labeling isolated packets as malicious.

Approach: Nmap-generated discovery traffic was inspected in Wireshark. A separate controlled exercise captured approximately 65,000 SYN packets across a full-range scan and ten SYN probes in a distinct test.

Analysis: five traffic patterns were documented. Service-discovery behavior was mapped to ATT&CK T1046 where supported, with the assessment kept within the isolated lab scope.

Evidence boundary: this demonstrates controlled traffic capture and analysis. It does not claim exploitation, access to data, a real-world compromise, or an automated network alert.

Web Application Vulnerability Assessment & Mitigation (DVWA)

  • Assessed a self-hosted DVWA instance at the Low security setting in an isolated Kali Linux lab.
  • Confirmed SQL injection, reflected and stored XSS, OS command injection, and security-misconfiguration findings with recorded evidence.
  • Tested seven candidate areas: brute force was not tested, and access-control testing was inconclusive—not a confirmed vulnerability.
  • Documented CVSS-based severity and remediation guidance. No remediation retest is claimed.
  • Nessus and OpenVAS results were excluded because those scans targeted other hosts; they are not represented as DVWA findings.
Read detailed project notes

Objective: assess an intentionally vulnerable training application, keep the target boundary explicit, and tie each reported issue to in-scope evidence.

Scope: the target was a self-hosted DVWA instance at Low security in an isolated Kali Linux lab. Results from Nessus and OpenVAS scans of other hosts were excluded from the DVWA findings.

Findings: five issues were documented: SQL injection, reflected XSS, stored XSS, OS command injection, and security misconfiguration. The report rates command injection High and SQL injection/XSS Medium for this training target and provides remediation guidance.

Testing limits: brute-force testing was not performed, access-control testing was inconclusive, and no remediation retest is claimed. These limits prevent the assessment from overstating coverage or fix verification.

Detection use cases & validation status

Detection work is more than a rule name: it needs a defined signal, contextual triage, a tested outcome and an honest validation status. The use cases below separate observed evidence from detection efficacy.

1Threshold search demonstrated
2Network / session evidence analyzed
404 eventsPowerShell telemetry present
0 / 13LimaCharlie rules tested
DET-01 · AUTHENTICATION

Repeated failed logons

Lab search demonstrated
Signal
Windows Security Event ID 4625, grouped by source address and target account with a lab threshold of five.
Triage
Review event channel, account, source, logon type, and status; check whether the pattern matches known lab activity.
Observed outcome
Five failures from loopback against a local test account. SOC-001 was investigated and closed as controlled activity; compromise was not observed.
Next test
Capture saved-alert configuration and a triggered result; then test 4624-after-4625 correlation and Event ID 4740 monitoring.

Interpretation: This demonstrates a search and investigation—not a documented saved alert firing or a real brute-force incident.

DET-02 · SCRIPT-BLOCK TELEMETRY

PowerShell activity review

Telemetry observed
Signal
PowerShell Operational Event ID 4104; 404 events are reported in the Splunk lab.
Current evidence
Event collection and review are documented. The report lists deeper PowerShell hunting as follow-up work.
Triage focus
Examine the event context and script-block content before judging whether the activity is expected or suspicious.
Next test
Run one benign, documented script scenario and capture the query, matching events, analyst interpretation, and false-positive considerations.

Interpretation: Event presence confirms telemetry—not a tested detection or a malicious-script finding.

DET-03 · NETWORK RECONNAISSANCE

Network service discovery

Traffic captured
Signal
Wireshark packet captures from controlled Nmap discovery and a separate hping3 exercise.
Observed behavior
The report documents an approximately 65,000-SYN full-range scan and a separate ten-probe test.
Analyst assessment
Lab reconnaissance traffic was analyzed in context. No exploitation or compromise is claimed.
Next test
Preserve a repeatable capture filter, compare scan traffic against a benign lab baseline, and record the distinguishing features.

Interpretation: Packet behavior was observed and analyzed; an automated network alert was not demonstrated.

DET-04 · ENDPOINT RULE DESIGN

Scheduled-task activity

Rule validation pending
Telemetry
Windows endpoint activity and LimaCharlie detection-and-response rule design.
Controlled activity
A benign scheduled task was created, checked, and removed; this establishes the test action, not a detection alert.
Validation status
The EDR report records 0 of 13 rules tested and shows no custom rule firing or investigated alert.
Next test
Trigger a benign task-creation scenario and capture the source event, matching rule, alert, and response before evaluating efficacy.

Interpretation: Detection logic is designed; alert efficacy remains unverified.

DET-05 · SSH HONEYPOT SESSION

Cowrie login & shell activity

Session analyzed
Signal
Cowrie text and JSON events for authentication, source address, session ID, commands, and session close.
Observed outcome
One author-generated Kali test session, one accepted login, five emulated commands, and zero failed logins.
Analyst assessment
Correlated the events into a single session and mapped supported SSH access and discovery-like commands with stated limitations.
Next test
Generate additional authorized test cases, including recorded failed logins, before evaluating credential-abuse patterns.

Interpretation: The shell is emulated; commands did not execute on the Ubuntu host. This is session analysis, not evidence of a real attacker or compromise.

Validation key: “Telemetry observed” means events were present; “traffic captured” or “session analyzed” means recorded activity was reviewed; “search demonstrated” means the documented analytic was used in a lab investigation. None implies production monitoring. “Rule validation pending” means no efficacy claim can yet be made.

// case study

SOC-001: investigating repeated failed logons

A real investigation from my Splunk lab: five Event ID 4625 failures detected, triaged field by field, validated and closed as controlled test activity.

1,767Events Ingested
54625 Failures
694624 Events Seen
404PowerShell 4104 Events

Lab architecture

  • Ubuntu VM running Splunk Enterprise 10.4.3 as the lab server.
  • Windows 10 VM running Splunk Universal Forwarder 10.4.3; both hosted in VMware Workstation.
  • Forwarding over TCP 9997 into a dedicated index: Security, System, Application and PowerShell Operational logs.

Detection search (lab-adapted SPL)

index=soc-project1 LogName=Security EventCode=4625
| eval target_user=mvindex(Account_Name,1)
| stats count by Source_Network_Address, target_user
| where count >= 5
| sort -count

Result

Five failures for a local test account from loopback — a candidate investigated as controlled activity, not a confirmed incident.

Investigation record

  • Date: 20 Sep 2026
  • Context: local test account and loopback source on the lab endpoint
  • Findings: five Security 4625 events, interactive logon type, bad-password status
  • Compromise: not observed · Decision: controlled test activity, case closed

Lessons learned

  • Filter on the Security log — Application-log records can also use event ID 4625.
  • Use the actual extracted fields for account, source address and logon type.
  • Use a stable, documented server address; the forwarder stopped after the lab server address changed.
  • Next detection work: add 4740 monitoring and test 4624-after-4625 correlation.

Implementation status — what is built and what is next

✅ Implemented

  • Splunk Enterprise, index and TCP 9997 receiving
  • Universal Forwarder and Windows log ingestion
  • 4625 investigation and threshold detection logic
  • SOC-001 incident case
  • LimaCharlie sensor enrolment and benign scheduled-task test

🛠️ Designed / in progress

  • 4624 correlation after repeated failures
  • Six-panel SOC dashboard and five-minute alert
  • PowerShell 4104 hunting (404 events present)
  • LimaCharlie rule validation: alert, process tree, response

🔭 Planned

  • Sysmon telemetry
  • Linux SSH (auth.log) monitoring
  • Multi-endpoint correlation
  • API-driven reporting

Evidence boundary: SOC-001 is a closed benign lab case, not a real-world compromise. The source report does not include the saved-alert configuration screenshot or evidence of an alert firing, and it does not establish that the full six-panel dashboard was completed.

More security case studies

Three project reports add detail behind the portfolio summaries. Each write-up below separates observed lab evidence from tests or outcomes that still need validation.

Network analysis · Wireshark · Nmap

Mini SOC network traffic investigation

A controlled investigation in an isolated Kali Linux and target-VM lab, following discovery, packet capture, analysis and written findings.

~65KTCP SYNs in full-range scan
10Controlled SYN probes
5Patterns documented

Method and evidence

  • Used Nmap to discover services and a full TCP port range, then reviewed packet behavior in Wireshark.
  • Captured a separate ten-packet hping3 SYN test; observed responses without completing the TCP handshake.
  • Mapped reconnaissance to MITRE ATT&CK T1046 and documented other traffic patterns for analyst review.

Scope and outcome

All activity was generated in the controlled lab. Findings describe observed lab traffic—not an external attack, a confirmed compromise, or successful exploitation. The report includes hardening recommendations; it does not claim production remediation.

Web application security · DVWA · OWASP

Evidence-based vulnerability assessment

Manual testing of a self-hosted DVWA instance at the Low security setting, using a local Kali Linux lab and an evidence register.

5Confirmed findings
1Area inconclusive
1Area not tested

Confirmed findings

  • SQL injection; reflected and stored cross-site scripting; OS command injection; and security misconfiguration, including exposure issues.
  • The report rates command injection High and SQL injection/XSS findings Medium, with severity based on evidence from this low-security training target.
  • Remediation guidance is documented, but fixes and retesting are not claimed.

Scope and integrity

Brute-force testing was not performed and access-control testing was inconclusive. OpenVAS and Nessus results were excluded because those scans targeted other hosts—not the DVWA system. Only in-scope evidence supports the findings above.

Endpoint detection · LimaCharlie · Windows

Windows EDR lab: implementation before validation

Built and documented a Windows endpoint monitoring lab, enrolled a sensor and configured detection-and-response scenarios.

Detection tests pending

Work documented

  • Windows 10 endpoint setup and telemetry baseline in the LimaCharlie console.
  • Rule scenarios for PowerShell execution, a cmd.exe-to-PowerShell process chain, scheduled-task creation and process-to-network activity.
  • A benign scheduled task was created, checked and removed as a controlled test (MITRE ATT&CK T1053.005).

The report records 0 of 13 rules tested and does not show a custom rule firing or an alert being investigated. Rule efficacy, incident triage and response outcomes remain future validation—not completed results.

Public evidence note: These summaries use verified, non-sensitive details from the project reports. The original reports are not linked here because they contain student identifiers and internal-lab details and are marked for educational/internal use.

What I'm building toward

The concrete next steps from my own project reports.

Now

Complete the SIEM workflow

Validate 4624-after-4625 correlation, build the six-panel dashboard and trigger the five-minute brute-force alert with evidence.

Next

Broaden telemetry

Add Sysmon and Linux SSH logs, then fire and document each LimaCharlie rule with alert, process tree and response.

Then

Scale and certify

Multi-endpoint correlation, API-based reporting, and a recognised SOC / blue-team certification.

// faq
