What do you need to know about attack surface analysis?
Attack Surface Analysis is usually done by security architects and pen testers. But developers should understand and monitor the Attack Surface as they design and build and change a system. Attack Surface Analysis helps you to: identify what functions and what parts of the system you need to review/test for security vulnerabilities
What happens to the attack surface when you add a field?
The first web page that you create opens up the system’s Attack Surface significantly and introduces all kinds of new risks. If you add another field to that page, or another web page like it, while technically you have made the Attack Surface bigger, you haven’t increased the risk profile of the application in a meaningful way.
How is the attack surface calculated in OWASP?
They calculate the Attack Surface as the sum of all entry and exit points, channels (the different ways that clients or external systems connect to the system, including TCP/UDP ports, RPC end points, named pipes…) and untrusted data elements.
What’s the difference between internal and external attack surfaces?
The internal attack surface is likely to be different to the external attack surface and some users may have a lot of access. Attack Surface Analysis is about mapping out what parts of a system need to be reviewed and tested for security vulnerabilities.
Which is the best tool for OWASP attack surface analysis?
For web apps you can use a tool like the OWASP ZAP or Arachni or Skipfish or w3af or one of the many commercial dynamic testing and vulnerability scanning tools or services to crawl your app and map the parts of the application that are accessible over the web.
What do you mean by attack surface in OSINT?
A key concept related to OSINT, and part of the reason why web software gets hacked, is the so-called “attack surface.” For this blog post, we’ll explore what an attack surface is, and share some valuable attack software analysis tools along with tips to help you reduce the attack surface area of your company.
Which is the best way to reduce attack surface?
There are several ways to reduce the attack surface. Let’s take a look at some of the more popular methods. The digital attack surface is the easiest to find and explore. Let’s explore the best attack surface reduction strategies?
