ANSWERS GRADED A 2024
conceptual design -Correct Answer ✔high level design that includes core components
of network architecture | 'black box' I/O | legal, environmental safety | customer
experience | multidisciplinary
logical design -Correct Answer ✔depicts how data flows across different devices in
network | detailed, rather than abstract network diagram | services, application names |
for developers and security architects | shows servers workstations routers firewalls...
physical design -Correct Answer ✔last before implementation | all known details |
physical components and connections | OS versions
communications flow -Correct Answer ✔dictated by logical design, shows how data
flows in and out of the network | informs threat model; attack surface and vectors;
estimate impact; determines defense
intellectual property (IP) -Correct Answer ✔dictated by logical architecture | key is
reduce number or locations where present; subject to copyright
router -Correct Answer ✔device that connects different networks together internal and
external | forwards data packets between computer networks | operates at OSI L3,
handles packets
switch -Correct Answer ✔networking device that connects computers together to form
physical and virtual networks | handles frames at OSI L2
Kismet -Correct Answer ✔Linux WLAN sniffer completely passive used for vulnerability
assessment and intrusion detection
threat enumeration -Correct Answer ✔list threat agents | list attack methods | list
system-level objectives
threat agents (3) -Correct Answer ✔human or not | organized crime | espionage |
hactivist
Advanced Persistent Threat (APT) -Correct Answer ✔An organized group of attackers
who are highly motivated, skilled, and patient. They are often sponsored by a

DoS -Correct Answer ✔An availability attack, to consume resources to the point of
exhaustion; Denial of Service; flood of ICMP requests targets router takes down server
DDoS -Correct Answer ✔Denial of service attack committed using many computers,
usually zombies on a botnet.
packet sniffing -Correct Answer ✔capture network traffic for analysis | no longer
requires physical access to network due to prevalence of wifi
packet misroute -Correct Answer ✔malware on router sends traffic to evil location or
causes routing loops DoS or network congestion
XSS -Correct Answer ✔Cross-site scripting. Attacker redirects users to malicious
websites, steal cookies. E-mail can include an embedded HTML image object or a
JavaScript image tag as part of a malicious cross-site scripting attack. Prevent with
input validation.
CSRF -Correct Answer ✔Cross-Site Request Forgery--Third-party redirect of static
content within the security context of a trusted site.
SYN flood -Correct Answer ✔A type of DoS where an attacker sends a large amount of
SYN request packets to a server in an attempt to deny service.
TCP reset -Correct Answer ✔attacker sniffs target traffic the spoofs packet with RST
flag set to end session
routing table poisoning -Correct Answer ✔routers exchange data to build tables;
attacker injects bad data
CDP -Correct Answer ✔Cisco Discovery Protocol; transmits in the clear; manipulation
attack; disable this protocol
MAC flood -Correct Answer ✔An attack that sends numerous packets to the switch,
each of which has a different source MAC address, in an attempt to use up the memory
on the switch and switch can downgrade to hub
DHCP spoofing attack -Correct Answer ✔MitM attack listens for DHCP traffic then
sends attacker IP address as default gateway
STP -Correct Answer ✔Spanning Tree Protocol. Protocol enabled on most switches that
protects against switching loops. A switching loop can be caused if two ports of a switch
are connected together, such as those caused when two ports of a switch are
connected together.

physical topology -Correct Answer ✔how a network is wired together; includes wifi
ethernet -Correct Answer ✔a system for connecting a number of computer systems to
form a local area network, with protocols to control the passing of information and to
avoid simultaneous transmission by two or more systems.
full duplex -Correct Answer ✔simultaneous send / receive for two nodes; Any device
that can send and receive data simultaneously.
CSMA / CD -Correct Answer ✔Carrier Sense Multiple Access with Collision Detection. It
is the method for multiple hosts to communicate on a Ethernet.
subnet -Correct Answer ✔A logical subset of a larger network, created by an
administrator to improve network performance or to provide security.
Principle of Least Privilege -Correct Answer ✔A security discipline that requires that a
particular user, system, or application be given no more privilege than necessary to
perform its function or job.
protected enclave -Correct Answer ✔segment of internal network defined by common
security policies
SDN -Correct Answer ✔Software Defined Network | split network into subnets with
software | allows for micro-segmentation and traffic analysis between two endpoints
public internet -Correct Answer ✔publicly accessible system of networks that connects
computers around the world
semi-public internet -Correct Answer ✔reachable from internet; may have internet
access
middleware -Correct Answer ✔separate private DMZ from private network
private internet -Correct Answer ✔used exclusively within an organization is called an
DMZ -Correct Answer ✔A network between the internal network and the Internet with a
firewall on both sides.
border router -Correct Answer ✔between ISP and org firewall; prefilters traffic before
org firewall and uses and ACL; aka edge router

compromised cannot compromise other systems
OS virtual machine -Correct Answer ✔multiple operating systems run independently on
the same hardware
virtualization -Correct Answer ✔emulation software for virtualization| allows a single
computing device to run multiple operating systems through hardware emulation |
accesses virtualized hardware, not physical
hypervisor -Correct Answer ✔emulation software for virtualization; allows a single
computing device to run multiple operating systems through hardware emulation
VM escapes -Correct Answer ✔attack to escape guest OS compromise hypervisor
virtual machine introspection -Correct Answer ✔monitor hypervisor and all VMs
virtual sprawl -Correct Answer ✔number of VMs / guest systems too big to manage
air gap -Correct Answer ✔physical separation of hardware (servers)
DMA -Correct Answer ✔Direct memory access (DMA) is a feature which allows for the
accessing of memory and controllers (video and network cards), without utilizing the
CPU such
hyperjacking -Correct Answer ✔compromise the hypervisor to gain access to the VMs
and their data typically launched against type 2 hypervisors that run over a host OS
hyperjumping -Correct Answer ✔attacker compromises one guest OS and jumps to
another | lateral compromise
