Seven phases of penetration testing

Pre-engagement interactions – Defines the scope, objectives, and rules of engagement before testing begins. Intelligence gathering – Uses passive and active reconnaissance to collect information about the target. Threat modeling – Identifies potential attack vectors based on the gathered intelligence. Vulnerability analysis – Examines weaknesses in networks, applications, and infrastructure. Exploitation – Attempts to gain unauthorized access using exploits tailored to discovered vulnerabilities. Post-exploitation – Establishes persistence, escalates privileges, and extracts valuable data. Reporting and remediation planning – Provides detailed reports and actionable steps for fixing vulnerabilities.

DREAD Model

Key Features

Evaluates risks based on five factors:

Damage potential: How severe is the impact? Reproducibility: How easily can the attack be replicated? Exploitability: How easy is it to exploit? Affected users: How many users are impacted? Discoverability: How easy is it to find the vulnerability?

Damage potential: How severe is the impact?
Reproducibility: How easily can the attack be replicated?
Exploitability: How easy is it to exploit?
Affected users: How many users are impacted?
Discoverability: How easy is it to find the vulnerability?
Uses a scoring system to assign numerical values to each factor, helping security teams prioritize threats.

Use Case

Used in risk-based vulnerability assessments to quantify and rank threats.
Helps security teams focus on high-risk vulnerabilities with the greatest potential impact.

Real-Life Example

A penetration test reveals an SQL injection vulnerability in a banking website. Using the DREAD model:

Damage potential: High (exposes sensitive financial data).
Reproducibility: High (attack can be executed easily with automated tools).
Exploitability: Medium (requires knowledge of SQL syntax).
Affected users: High (large user base).
Discoverability: High (attack can be detected using public scanners).

The high DREAD score prompts the security team to fix the vulnerability immediately.
