characteristic features of a WPA/WPA2 Enterprise mode - ANSWER: characteristic
features of a WPA/WPA2 Enterprise modeSuitable for large corporate networks and
MS Windows utility designed both for system administrators and for application
developers - ANSWER: MS Windows utility designed both for system administrators
and for application developers
HFS - ANSWER: Hierarchical File System, before OS X, where files were stored in
directories (folders) that can be nested in other directories.
NTFS - ANSWER: New Technology File System, is a process that the Windows NT
operating system uses for storing, organizing, and finding files on a hard disk
efficiently. NTFS was first introduced in 1993, as apart of the Windows NT 3.1
release.
FAT32 - ANSWER: File system used by older Windows systems.
NFS - ANSWER: The network file system and was created by Sun Microsystems for
network file shares.
gpupdate - ANSWER: The gpupdate command refreshes a computer's local Group
Policy, as well as any Active Directory-based group policies. This command works on
Windows 10, 8, 7, Vista, and XP. The gpupdate command can be used to restrict
access to USB removable storage devices (like USB thumb drives and hard drives)
GPRESULTS - ANSWER: Command line tool that shows the Resultant Set of Policy
(RsoP) information for a user and computer. In other words, it creates a report that
displays what group policies objects are applied to a user and computer
SFC - ANSWER: System File Checker (SFC) to scan Windows and restore your system
files.
MSCONFIG - ANSWER: The filename for the System Configuration Utility, which
allows you to test various scenarios for Windows startup for troubleshooting
purposes. (11)
Boot Camp - ANSWER: Boot Camp is used to allow dual booting on a Macintosh
computer. It allows the user to boot into either macOS (OS X) or Windows as the
computer is rebooted.
,chmod - ANSWER: The chmod command is used to change the permissions of a file
or directory from the command line or terminal.
chown - ANSWER: chown command is used to change the owner of the file, but not
its permissions.
sudo - ANSWER: The sudo command allows a command to be executed as the super
user (root) instead of as the current user.
pwd - ANSWER: *PRESENT WORKING DIRECTORY*
The pwd is used to display the path to the present working directory (current
directory) to the terminal or display.
PIV - ANSWER: *Personal identity verification* card. A specialized type of smart card
used by United States federal agencies. It includes photo identification and provides
confidentiality, integrity, authentication, and non-repudiation for the users. It is
similar to a CAC.
CAC - ANSWER: Common Access Card
unattended installation - ANSWER: A Windows installation that is done by storing the
answers to installation questions in a text file or script that Windows calls an answer
file so that the answers do not have to be typed in during the installation.
WPS - ANSWER: WPS was created to ease the setup and configuration of new
wireless devices by allowing the router to automatically configure them after a short
eight-digit PIN was entered. Unfortunately, WPS is vulnerable to brute-force attack
and is easily compromised. Therefore, WPS should be disabled on all wireless
networks. If Bob was able to enter your apartment and press the WPS button, he
could have configured his laptop to use your wireless network without your WPA2
password.
WEP (Wired Equivalent Privacy) - ANSWER: Wired Equivalent Privacy (WEP) is a
security protocol, specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b,
that is designed to provide a wireless local area network (WLAN) with a level of
security and privacy comparable to what is usually expected of a wired LAN. It is the
oldest form of wireless security and the weakest form. WEP can be cracked with
brute force techniques in less than 5 minutes with a normal end-user computer.
RADIUS - ANSWER: Remote Authentication Dial-In User Service (RADIUS) is a
networking protocol, operating on port 1812, that provides centralized
Authentication, Authorization, and Accounting (AAA or Triple A) management for
users who connect and use a network service.
TACACS+ - ANSWER: Terminal Access Controller Access-Control System Plus
(TACACS+) is a protocol developed by Cisco and released as an open standard
, beginning in 1993. Although derived from TACACS, TACACS+ is a separate protocol
that handles authentication, authorization, and accounting (AAA) services.
TACAS - ANSWER: Terminal Access Controller Access Control System
Difference between TACACS+ and RADIUS. - ANSWER: TACACS+ provides more
control over the authorization of commands while in RADIUS, no external
authorization of commands is supported. All the AAA packets are encrypted in
TACACS+ while only the passwords are encrypted in RADIUS i.e more secure....
zero-day attack - ANSWER: Attack between the time a software vulnerability is
discovered and a patch to fix the problem is released.
rogue antivirus - ANSWER: Rogue antivirus is a form of malicious software and
Internet fraud that misleads users into believing there is a virus on their computer,
and to pay money for a fake malware removal tool (that actually introduces malware
to the computer). It is a form of scareware that manipulates users through fear, and
a form of ransomware
seven steps of the malware removal procedures - ANSWER: Identify and research
malware symptoms,
Quarantine the infected systems,
Disable System Restore (in Windows),
Remediate the infected systems, update the anti-malware software, scan the
system, and use removal techniques (safe mode, pre-installation environment),
Schedule scans and run updates,
Enable System Restore and create a restore point (in Windows),
Educate the end user.
IQDRUSSEE (I Quote the DR of the USS Enterprise E) - ANSWER: Identify
Quarantine
Disable
Remediate
Update
Schedule
Scan
Enable
Educate
WAP - ANSWER: Wireless Access Point
Backout plan - ANSWER: backout plan is an IT governance integration approach that
specifies the processes required to restore a system to its original or earlier state, in
the event of failed or aborted implementation.
