Welcome to Headsec

An introduction to my cybersecurity-focused portfolio and blog.

Welcome#

This is a demonstration post to showcase the capabilities of my portfolio and blog platform.

Features#

This platform includes several key features designed for technical content:

Code Blocks with Syntax Highlighting#

Here's an example of a code block with copy functionality:

text
// Example: Detecting DNS beaconing patterns
function analyzeBeaconing(requests: DNSRequest[]): boolean {
  const intervals = requests
    .sort((a, b) => a.timestamp - b.timestamp)
    .map((req, i, arr) => {
      if (i === 0) return 0
      return req.timestamp - arr[i - 1].timestamp
    })
    .filter(interval => interval > 0)
 
  // Calculate coefficient of variation
  const mean = intervals.reduce((a, b) => a + b, 0) / intervals.length
  const variance = intervals
    .map(x => Math.pow(x - mean, 2))
    .reduce((a, b) => a + b, 0) / intervals.length
  const stdDev = Math.sqrt(variance)
  const cv = stdDev / mean
 
  // Low CV indicates regular intervals (potential beaconing)
  return cv < 0.3
}

Callouts for Important Information#

Pro Tip

Use the copy button in the top-right corner of code blocks to quickly copy code snippets to your clipboard.

Did you know?

This platform respects your prefers-reduced-motion setting. If you have motion preferences enabled, the Matrix rain animation will be automatically disabled.

Security Note

When analyzing malware or suspicious code, always use an isolated environment and proper sandboxing techniques.

Content Organization#

Content is organized into three main types:

  1. Posts (Blog) - Long-form writeups, tutorials, and technical articles
  2. Projects - Project showcases and case studies

Each piece of content can be tagged with:

  • Topics: High-level categories (e.g., Threat Hunting, Web Security)
  • Tools: Specific technologies used (e.g., Zeek, Burp Suite, Ghidra)
  • Tags: Granular keywords (e.g., dns, beaconing, blueteam)

Design Philosophy#

The design emphasizes:

  • Readability: Generous line heights and optimal line lengths (~70ch) for comfortable reading
  • Performance: Lighthouse scores of 95+ across all metrics
  • Accessibility: WCAG AA compliance, keyboard navigation, screen reader support
  • Dark Theme: Matrix-inspired color palette with neon green (#00ff9c) and cyan accents

Table of Contents#

Notice the table of contents on the right (desktop) that automatically tracks your reading position. Click any heading to jump to that section.

What's Next?#

Future enhancements planned:

  • Interactive lab walkthroughs

Toggle the Matrix rain animation using the button in the bottom-right corner. Your preference is saved to localStorage.
