Used to upload and download files to an FTP server.
FTP uses TCP ports 20 and 21.
Card 85
Question
FTPS
Answer
File Transfer Protocol Secure.
An extension of FTP that uses SSL to encrypt FTP traffic.
Some implementations of FTPS use TCP ports 989 and 990.
Card 86
Question
GPG
Answer
GNU Privacy Guard (GPG).
Free software based on the OpenPGP standard and used to encrypt and decrypt files.
It is similar to PGP but avoids any conflict with existing licensing by using open standards.
Card 87
Question
GPO
Answer
Group Policy Object.
Group Policy is used within Microsoft Windows to manage users and computers.
It is implemented on a domain controller within a domain.
Administrators use it to create password policies, lock down the GUI, configure host-based firewalls, and much more.
Card 88
Question
GPS
Answer
Global Positioning System.
GPS tracking can help locate lost mobile devices.
Remote wipe, or remote sanitize, erases all data on lost devices.
Full disk encryption protects the data on the device if it is lost.
Card 89
Question
GRE
Answer
Generic Routing Encapsulation.
A tunneling protocol developed by Cisco Systems.
Card 90
Question
GUI
Answer
Graphical user interface.
Users interact with the graphical elements instead of typing in commands from a text interface.
Windows is an example of a GUI.
Card 91
Question
HDD
Answer
Hard disk drive.
A disk drive that has one or more platters and a spindle.
In contrast, USB flash drives and SSD drives use flash memory.
Card 92
Question
HIDS
Answer
Host-based intrusion detection system.
An IDS used to monitor an individual server or workstation.
It protects local resources on the host such as the operating system files, and in some
cases, it can detect malicious activity missed by antivirus software.
Card 93
Question
HIPS
Answer
Host-based intrusion prevention system.
An extension of a host-based IDS.
Designed to react in real time to catch an attack in action.
Card 94
Question
HMAC
Answer
Hash-based Message Authentication Code.
A hashing algorithm used to verify integrity and authenticity of a message with the use of shared secret.
When used with TLS and IPsec, HMAC is
combined with MD5 and SHA-1 as HMAC-MD5 and HMAC-SHA1, respectively.
Card 95
Question
HOTP
Answer
HMAC-based One-Time Password (HOTP).
An open standard used for creating one-time passwords, similar to those used in tokens or key fobs.
It combines a secret key and an incrementing counter, and then uses HMAC to create a hash of the result.
HOTP passwords do not expire until they
are used.
Card 96
Question
HSM
Answer
Hardware security module.
A removable or external device that can generate, store, and manage RSA keys used in asymmetric encryption.
High-volume e-commerce sites use HSMs to increase the performance of SSL sessions.
High-availability clusters needing encryption services can use clustered HSMs.
Card 97
Question
HTML
Answer
Hypertext Markup Language.
Language used to create web pages.
HTML documents are displayed by web browsers and delivered over the Internet using HTTP or HTTPS.
It uses less-than and greater-than characters (< and >) to create tags.
Many sites use input validation to block these tags and prevent cross-site scripting attacks.
Card 98
Question
HTTP
Answer
Hypertext Transfer Protocol.
Used for web traffic on the Internet and in intranets.
HTTP uses TCP port 80.
Card 99
Question
HTTPS
Answer
Hypertext Transfer Protocol Secure.
Encrypts HTTP traffic with SSL or TLS using TCP port 443.
Card 100
Question
HVAC
Answer
Heating, ventilation, and air conditioning.
HVAC systems increase availability by regulating airflow within data centers and server rooms.
They use hot and cold aisles to regulate the cooling, thermostats to ensure a relatively constant temperature, and humidity controls to reduce the potential
for static discharge, and damage from condensation.
Higher-tonnage HVAC systems provide more cooling capacity to keep server rooms at operating temperatures, resulting in fewer failures and
longer MTBF times.
HVAC systems should be integrated with fire alarm systems and either have
dampers or the ability to be turned off in the event of a fire.
