MAVERICK [17]

Answer:

See explaination

Explanation:

import re

def isValidTrain(train):

pattern = r'^E+(((P|PP|PPP|PPPP)D)*(BB)*)*C$'

if re.match(pattern, train):

return True

return False

def checkAndPrintTrain(train):

print("Train", train, "is valid:", isValidTrain(train))

checkAndPrintTrain("EC")

checkAndPrintTrain("EEEPPDBBPDBBBBC")

checkAndPrintTrain("EEBB")

checkAndPrintTrain("EBBBC")

checkAndPrintTrain("EEPPPPPPDBBC")

checkAndPrintTrain("EEPPBBC")

checkAndPrintTrain("EEBBDC")

Sample output

Train EC is valid: True

Train EEEPPDBBPDBBBBC is valid: True

Train EEBB is valid: False

Train EBBBC is valid: False

Train EEPPPPPPDBBC is valid: False

Train EEPPBBC is valid: False

Which form of investigation aims at checking whether or not a target system is subject to attack based on a database of tests, s

VikaD [51]

Answer:

<em>Empirical technical </em>research has a fundamental objective, which is to provide objective and independent information on the quality of the product to the interested party or stakeholder. It is one more activity in the quality control process.

Explanation:

Testing is basically a set of activities within software development. Depending on the type of tests, these activities may be implemented at any time during said development process. There are different software development models, as well as test models. Each one has a different level of involvement in development activities.

In a full penetration testing process, there are pre-instances to run this tool, but to take the first steps it is probably the best way to start. Nmap is a network scanning tool that allows you to identify what services are running on a remote device, as well as the identification of active computers, operating systems on the remote computer, existence of filters or firewalls, among others.

In simple words, when a server or device is going to be attacked, the attacker can carry out different attacks depending on the service: it is not the same to damage a web server, a database server or a perimeter router. Therefore, in any deployment, the first step will be to identify the services in the infrastructure, to decide how to proceed and, considering that in a penetration test the steps of an attacker are “imitated”, it will also be started in the same way.
