System Secured

This flow shows how we find parts of a system that attackers can target (attack surfaces), understand how they might attack (vectors), and then protect the system.

Execution Sample

Cybersecurity

System Components: Web Server, Database, User Interface
Attack Surfaces: Open Ports, User Input Fields, APIs
Attack Vectors: SQL Injection, Phishing, Malware
Security Action: Patch software, Validate input, Educate users

This example lists system parts, identifies attack surfaces, shows attack methods, and security steps.

Analysis Table

Step	Action	Details	Result
1	Identify Components	Web Server, Database, User Interface	System parts listed
2	Find Entry Points	Open ports, Input fields, APIs	Potential attack surfaces found

4	Analyze Vectors	SQL Injection, Phishing, Malware	Ways attackers can exploit surfaces
5	Apply Security	Patch software, Validate input, Educate users	Surfaces reduced and protected
6	Monitor System	Watch logs and alerts	Detect attack attempts
7	End	All steps done	System security improved

💡 All attack surfaces identified and protected, monitoring ongoing

Key Insights - 3 Insights

Why do we separate attack surfaces from attack vectors?

Attack surfaces are the places attackers can try to enter, while attack vectors are the methods they use to get in. The execution_table shows surfaces identified first (Step 3) and then vectors analyzed (Step 4).

Can an attack surface exist without an attack vector?

Yes, an attack surface is just a possible entry point. If no method (vector) is known or possible, it is still a surface but less risky. The table shows surfaces found before vectors are analyzed.

Why is monitoring important after securing attack surfaces?

Because attackers may try new vectors or exploit unknown surfaces. Monitoring (Step 6) helps detect attempts early, as shown in the execution_table.

Visual Quiz - 3 Questions

Look at the execution_table at Step 2. What is identified as attack surfaces?

A Open ports, Input fields, APIs

B SQL Injection, Phishing, Malware

C Patch software, Validate input

D Web Server, Database, User Interface

💡 Hint

Check the 'Details' column at Step 2 in the execution_table.

At which step in the execution_table do we analyze how attackers can exploit the system?

A Step 2

B Step 5

C Step 4

D Step 6

💡 Hint

Look for the step mentioning 'Attack Vectors' in the 'Details' column.

If we add a new user input field, how would the variable 'Attack Surfaces' change in variable_tracker?

A It would stay the same

B It would increase

C It would decrease

D It would become empty

💡 Hint

Adding an input field adds a new entry point, increasing attack surfaces as shown in variable_tracker.

Monitor the system to catch attacks early.

Full Transcript

Attack surfaces are the parts of a system that can be targeted by attackers, like open ports or user input fields. Attack vectors are the ways attackers use these surfaces to get in, such as SQL injection or phishing. The process starts by listing system components, then finding possible entry points which become attack surfaces. Next, we analyze how attackers might exploit these surfaces, called attack vectors. After that, security measures like patching software and validating inputs reduce the risk. Finally, monitoring helps detect any attack attempts. This step-by-step approach helps keep systems safer.
