Exam Questions and CORRECT Answers
Do You Filter Ports On The Firewall? - CORRECT ANSWER- ✔✔You can filter ports on the
firewall to block specific malware and protect the network from unnecessary traffic. For
instance, some companies block port 21, the FTP port, when the company does not host or
allow FTP communications.
How Does Tracerout Or Tracert Work? - CORRECT ANSWER- ✔✔traceroute and tracert
work to determine the route that goes from the host computer to a remote machine. It's used
to identify if packets are redirected, take too long, or the number of hops used to send traffic
to a host.
What Are The Strengths And Differences Between Windows And Linux? - CORRECT
ANSWER- ✔✔Linux has some commands that Windows does not, but Windows is not open
source and does not suffer from recent hacks such as Heartbleed.
How Can You Encrypt Email Messages? - CORRECT ANSWER- ✔✔You can use PGP to
encrypt email messages or some other form of a public private key pair system where only
the sender and the recipient can read the messages.
What Kind Of Penetration Can Be Done With The Diffie Hellman Exchange? - CORRECT
ANSWER- ✔✔A hacker can use the man in the middle attack with the Diffie Hellman
exchange since neither side of the exchange is authenticated. Users can use SSL or encryption
between messages to add some kind of security and authentication.
How Do You Add Security To A Website? - CORRECT ANSWER- ✔✔The HTTP protocol
allows for security behind authenticated pages and directories. If the user does not enter the
right username and password, the server returns a 403 authentication HTTP error. This
protects from unauthorized users.
What Are Some Ways To Avoid Brute Force Hacks? - CORRECT ANSWER- ✔✔You can
stop authentication after a certain amount of attempts and lock the account. You can also
block IP addresses that flood the network. You can use IP restrictions on the firewall or
server.
, What Type Of Tools Are There Out There For Packet Sniffing? - CORRECT ANSWER-
✔✔Wireshark is probably the most common packet sniffing tool. This program can help you
find odd traffic across the network or identify a program that is sending traffic silently from a
host.
What Is The Difference Between Asymmetric And Symmetric Encryption? - CORRECT
ANSWER- ✔✔Symmetric encryption uses the same key for decryption and encryption.
Asymmetric uses different keys.
Why Should We Conduct A Penetration Test? - CORRECT ANSWER- ✔✔IT is an integral
part of every company's business today. Therefore, not only the amount of business-critical
data that is stored on IT systems grows, but also the dependency on a working IT
infrastructure. This leads to an increased amount of attacks against IT systems in the form of
industrial espionage, denial of service attacks and other possibilities to significantly harm a
company. Important corporate secrets are spied on and sold to competitors.
The availability of systems is interrupted, as a non-working IT is causing more and more
problems today. No new orders are placed, because competitors somehow always have the
better offer. A penetration test gives you information about your systems' vulnerabilities, how
probable a successful attack against your infrastructure is and how you can protect yourself
against potential security breaches in the future.
Are There Legal Requirements For Penetration Tests? - CORRECT ANSWER- ✔✔It may
not be mandatory to do a penetration test for corporations, but the German law for example
includes numerous text passages in its commercial laws which could be validated by
conducting a penetration test.
What Is The Workflow Of A Penetration Test? - CORRECT ANSWER- ✔✔In advance of
every penetration test, an individual meeting is held. In this meeting, the various possibilities
of a penetration test in relation to the customer's systems are discussed. A penetration test
only makes sense if it is realised in an individual and customer-oriented way.
What Time Investment Do You Estimate For A Penetration Test? - CORRECT ANSWER-
✔✔The time investment for a penetration test varies from case to case depending on the
systems to be tested and the individual test requirements. Usually, the time needed ranges
from a few days to several weeks. One goal of the preliminary meeting is to get enough
information about the systems to be tested to estimate the optimal length for the penetration
test.
