A fine-tuned Mistral-7B model specialized in Security Information and Event Management (SIEM) log analysis and generation. This model has been trained using QLoRA (4-bit quantization) on multiple cybersecurity log sources to understand and generate security-related event data.

Model Description

This model is a specialized variant of Mistral-7B-Instruct fine-tuned for SIEM operations, including:

Network traffic analysis (DDoS detection, port scanning)
Authentication event monitoring (credential stuffing, brute force)
Cloud security events (AWS CloudTrail analysis)
System log interpretation
MITRE ATT&CK framework mapping

Training Data Sources

The model was trained on a diverse set of security logs:

Network Logs: CICIDS2017 dataset (DDoS, PortScan patterns)
Authentication Logs: Risk-based authentication events
System Logs: Linux/Unix syslog events
Cloud Logs: AWS CloudTrail security events

MITRE ATT&CK Coverage

The model recognizes and maps events to MITRE ATT&CK techniques:

T1499: Endpoint Denial of Service (DDoS)
T1046: Network Service Scanning
T1110: Brute Force
T1110.004: Credential Stuffing
T1078.004: Cloud Account Access

Usage

Installation

pip install transformers peft torch bitsandbytes accelerate

Loading the Model

python

from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

# Load base model with 4-bit quantization
base_model = "mistralai/Mistral-7B-Instruct-v0.2"
model = AutoModelForCausalLM.from_pretrained(
    base_model,
    load_in_4bit=True,
    device_map="auto"
)

# Load LoRA adapters
model = PeftModel.from_pretrained(model, "your-username/siem-log-generator-mistral-7b-qlora")
tokenizer = AutoTokenizer.from_pretrained("your-username/siem-log-generator-mistral-7b-qlora")

# Generate security event analysis
prompt = "<s>[INST] event=network attack=DDoS [/INST]"
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Inference Example

python

# Analyze a security event
event = "timestamp=2024-01-14T10:30:00Z event=auth user=admin attack=BruteForce"
prompt = f"<s>[INST] {event} [/INST]"

inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=150,
        temperature=0.7,
        top_p=0.9,
        do_sample=True
    )

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Use Cases

1. Security Event Classification

Classify incoming logs into attack types or benign traffic.

2. MITRE ATT&CK Mapping

Automatically map security events to MITRE ATT&CK framework techniques.

3. Log Enrichment

Generate additional context and metadata for security events.

4. Threat Intelligence

Analyze patterns and generate threat reports from log data.

5. Training Data Generation

Create synthetic security logs for testing SIEM systems.

Limitations

Training Data: Model trained on limited samples (~500) for demonstration
Domain Specific: Optimized for SIEM/security logs, not general purpose
Language: English only
Real-time: Not optimized for ultra-low latency applications
Accuracy: Should be used as an assistive tool, not sole decision-maker

Ethical Considerations
