# Technical Document Extraction: Network Traffic Frequency Analysis
## 1. Image Metadata & Classification
* **Type:** Stacked Bar Chart (Histogram)
* **Language:** English
* **Scale:** Logarithmic Y-axis (Base 10)
* **Primary Subject:** Frequency of network traffic types over a 60-second duration.
## 2. Component Isolation
### A. Header / Legend
* **Location:** Top-center, enclosed in a black-bordered box.
* **Categories (Color Coded):**
* **Theft:** Bright Pink
* **Reconnaissance:** Light Pink / Lavender
* **DDoS:** Blue
* **DoS:** Red
* **Benign:** Green
### B. Axis Definitions
* **Y-Axis (Vertical):**
* **Label:** Frequency
* **Scale:** Logarithmic, ranging from $10^0$ (1) to $10^7$ (10,000,000).
* **Markers:** $10^0, 10^1, 10^2, 10^3, 10^4, 10^5, 10^6, 10^7$.
* **X-Axis (Horizontal):**
* **Label:** Time in seconds
* **Range:** 0 to 60 seconds.
* **Markers:** Increments of 5 (0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60). Labels are rotated 45 degrees.
## 3. Data Series Analysis & Trends
### Benign (Green)
* **Trend:** Concentrated heavily in the first 15 seconds.
* **Behavior:** Peaks early (around 0-5 seconds) with frequencies between $10^3$ and $10^5$. It drops off sharply after 15 seconds, with only a negligible trace appearing near the 37-second mark.
### DDoS (Blue)
* **Trend:** Dominant high-frequency contributor in the first 25 seconds.
* **Behavior:** Maintains a high frequency (between $10^5$ and $10^6$) from 0 to 10 seconds. It shows a gradual decline but remains significant until approximately 32 seconds. It appears in isolated bursts between 35 and 45 seconds.
### DoS (Red)
* **Trend:** Persistent across the widest time range; becomes the dominant category after 25 seconds.
* **Behavior:** Initially stacked on top of DDoS traffic. After 23 seconds, while other categories drop, DoS maintains a frequency between $10^3$ and $10^5$. It is the only category present in the 45-50 second range and appears as a final outlier at 59-60 seconds.
### Reconnaissance (Light Pink)
* **Trend:** Short-lived, early-stage activity.
* **Behavior:** Primarily visible between 0 and 7 seconds. It reaches a peak frequency of approximately $10^4$ at the 1-second mark and disappears almost entirely after 15 seconds.
### Theft (Bright Pink)
* **Trend:** Minimal presence, highly localized.
* **Behavior:** Visible as small slivers at the base of the bars at 0, 1, 2, 4, and 23 seconds. Frequencies are very low, generally near the $10^0$ to $10^1$ range.
## 4. Key Data Observations (Spatial Grounding)
| Time Interval (s) | Dominant Traffic Type | Approximate Total Frequency |
| :--- | :--- | :--- |
| **0 - 5** | DDoS (Blue) & Benign (Green) | $10^6$ to $2 \times 10^6$ |
| **5 - 10** | DDoS (Blue) | $10^5$ to $10^6$ |
| **10 - 20** | DDoS (Blue) | $10^4$ to $10^5$ |
| **20 - 25** | DoS (Red) & DDoS (Blue) | $10^5$ |
| **25 - 35** | DoS (Red) | $10^2$ to $10^4$ |
| **40 - 50** | DoS (Red) | $10^2$ to $10^3$ |
| **55 - 60** | DoS (Red) | $< 10^2$ (Single outlier) |
## 5. Summary of Findings
The chart illustrates a high-intensity burst of network activity in the first 10 seconds, primarily composed of **Benign** and **DDoS** traffic. As time progresses, **Benign**, **Reconnaissance**, and **Theft** traffic cease almost entirely. **DDoS** traffic persists until the 30-second mark, after which the remaining network activity is almost exclusively **DoS** (Denial of Service) attacks, which continue intermittently until the end of the 60-second observation period.
