A directory traversal (or path traversal) consists in exploiting insufficient security validation/sanitization of user-supplied input file names, so that characters representing "traverse to parent directory" are passed through to the file APIs.
The goal of this attack is to order an application to access a computer file that is not intended to be accessible.
This attack exploits a lack of security (the software is acting exactly as it is supposed to) as opposed to exploiting a bug in the code.
To perform a directory traversal attack, which sequence does a pen tester need to follow to manipulate variables of reference files?

Many security and compliance projects begin with a simple idea: assess the organization's risk, vulnerabilities, and breaches. Implementing an IT security risk assessment is critical to the overall security posture of any organization.
An effective security risk assessment can prevent breaches and reduce the impact of realized breaches.
What is the formula to calculate risk?

Port numbers are used to keep track of different conversations crossing the network at the same time. Both TCP and UDP use port (socket) numbers to pass information to the upper layers. Port numbers have the assigned ranges. The port numbers above 1024 are considered as which one of the following? (Select all that apply)

An external intrusion test and analysis identify security weaknesses and strengths of the client's systems and networks as they appear from outside the client's security perimeter, usually from the Internet. The goal of an external intrusion test and analysis is to demonstrate the existence of known vulnerabilities that could be exploited by an external attacker.
During external penetration testing, which of the following scanning techniques allow you to determine a port's state without making a full connection to the host?
