Penetration Testing Goals name six different testing methods and discuss which method is best when given the task of doing a security test be able to explain penetration testing name at least two standards providing guidance on how to do penetration testing explain the role and important parameters (scope, rules of engagement, test method) of the pre-engagement phase Reasons Why do we want to test? What’s our goal? Find and fix vulnerabilities?

Exploits Definition Is a piece of software, chunk of data, sequence of commands that take advantage of a vulnerability in an system Classification Often classified by their action Unauthorized data access arbitrary code execution denial of service privilege escalation Characterization local exploit remote exploit client-side exploit often requires some user action drive by attacks trigger fore example by malicious website server side exploit 0-day exploit Stack Layout CPU Registers esp stack pointer

Python For Loops really comfortable with range function: for n in range(2,10): for x in range(2, n): if n% x == 0: print(n, 'equals', x, '*', n//x) break else: #Loop fell through without finding a factor print(n, 'is a prime number') Scope Rules different Scopes local inside function(method,…) global in the surrounding modul built-in pre defined names(open, len,…) function call creates a local scope search order when reading local > global > built-in
