What section of the vulnerability report is used to identify mitigation strategies that can
be followed for a vulnerability?
A) Impact
B) Detection Result
C) Solution
D) Summary - Answer-C) Solution

What type of vulnerability assessment involves validating that data is accessed through
security controls such as parameterized queries?
A) Passive
B) Wireless
C) Active
D) Database - Answer-D) Database

Don't hard code keys into source code - Answer-People will reverse engineer code so
they can find the key in your source code. Outsource to a TPM to be secure.

Encrypt keys with passwords or passphrases - Answer-Add a password to encryption
keys so they have to know password to view them.

Use IDS to monitor key exchanges - Answer-Looking at traffic or signature based
activity and if it is a known crypto attack it will recognize those signatures
What command would do a time-to-live ACK scan to possibly map firewall rules?
A) nmap --ttl 70 10.10.10.10 --packet-trace
B) nmap 10.10.10.10 --ttl-packet-trace
C) nmap -t 70 -l 10 10.10.10.10 --packet-ttl
D) nmap --ttl 10.10.10.10 --timetolive 70 - Answer-A) nmap --ttl 70 10.10.10.10 --packet-
trace

What could it mean if we do an nmap ACK scan using "nmap --A 10.10.10.10" and we
get back "All 1000 scanned ports on 10.10.10.10 are unfiltered"?
A) It means nmap needed administrative privileges to run this scan
B) It means nmap could not scan the system or determine the state of any of the ports
C) It means the scanned target is filtered by a separate firewall or IDS that blocked all
communication
D) It means the scan got responses and an RST packet back for each port - Answer-D)
It means the scan got responses and an RST packet back for each port

What nmap command would do a scan against a target setting only the Push flag on the
packets?

,A) nmap --scanflags PSH 10.10.10.10
B) nmap -sP 10.10.10.10
C) nmap -sF -flag PSH 10.10.10.10
D) nmap -tcp --scan flag push 10.10.10.10 - Answer-A) nmap --scanflags PSH
10.10.10.10

What option added to the nmap command "nmap -sF 10.10.10.10" can give you
additional information about the state of a port when running a scan?
A) -show-response
B) -show
C) --reason
D) --diagnostics - Answer-C) --reason
key stretching - Answer-A technique used to increase the strength of stored passwords.
it adds additional bits (called salts) and can help thwart brute force and rainbow table
attacks. PBKDF2 (password based key derivation function).

Which component of Public Key Infrastructure prescreens the certificate signing request
for initial enrollment and verifies the requestor?
A) Registration Authority
B) Enrollment Authority
C) Certificate Authority
D) Signing Authority - Answer-A) Registration Authority

Which attack method is a "chosen plain text attack" which is based on being able to
provide your own plain text input to get the encrypted output?
A) Fractional
B) Constituent
C) Differential
D) Linear - Answer-C) Differential

What are some of the details a Certificate contains?
A) Root key
B) Mode
C) Issuer name
D) Fingerprints
E) Validity - Answer-C) Issuer name
D) Fingerprints
E) Validity
Confidentiality - Answer-the assurance that messages and information are available
only to those who are authorized to view them. Method of assurance is encryption

integrity - Answer-Data has not been changed or modified (in an unauthorized way).
True to what it should be. Done with hashin algortihms

Availability - Answer-Ability to access the data or information systems when you need to
access it

,Authenticity - Answer-Everything is as it says it was in the metadata (i.e: the private key
of a user that accessed the data actually belongs to that user)

hacktivism (campion a cause), political, religious, terrorism (impact critical infrastructure
that cases human casualties), revenge, cyber crime ($$)

Passive Attack - Attack Classification - Answer-Attack where the attacker does not
interact with processing or communication activities, but only carries out observation
and data collection, as in network sniffing. Sensitive information in clear text on the
network. Think Wireshark. HARD TO DETECT

Active Attack - Attack Classification - Answer-Manipulation of data, disruption of
services, compromising individual systems or network at large. Easier to detect (e.x.:
DoS, DDoS, password attacks, session hijacking, privilege escalation, SQL injection,
remote code execution)

Close-In Attack - Attack Classification - Answer-Through proximity (typically physical)
you gather sensitive information. Shoulder surfing is an example.

Insider Attack - Attack Classification - Answer-Trusted individual who abuses their trust
on a network to gain information. More devastating. (e.x.: pod slurping where you exfil

Offensive Information Warfare - Answer-web-based attacked system hacking, MITM

Defensive Information Warfare - Answer-Techniques we use to try and stop attacked.
Detection (IDS), prevention (IPS), alerting

Cyber Kill Chain - Reconnaissance (1) - Answer-Gathering and putting information
together about the target. Getting public info (email accounts, technologies used, DNS
spaces)

Cyber Kill Chain - Weaponization (2) - Answer-Finding possible exploitable
vulnerabilities in target system Create malicious deliverable payloads

Cyber Kill Chain - Delivery (3) - Answer-Handing malicious payload to target (e.x.: email
spearphishing, USB, website watering hole)

Cyber Kill Chain - Exploitation (4) - Answer-Target actually interacts with the deliverable

Cyber Kill Chain - Installation (5) - Answer-Delivered malicious code will download more
"dirty" code. More functionality downloaded. Maintaining access.

Cyber Kill Chain - Command and Control (6) - Answer-Ability of attacker to control
target. Use encryption to hide communication, privilege escalation. Hide presence.

Cyber Kill Chain - Actions & Objectives (7) - Answer-Why did he attacker care to gain
access to the system? What do they want? Doing the thing that led them to want to get
on to the network.
