IDSC IMPERVA DATA SECURITY CERTIFICATION
2026 ADVANCED EXAMINATION TEST
◉ LAN software and practices. Answer: Also need to provide for the
security of these programs and data
◉ most LAN software. Answer: Provides a low level of security
◉ The emphasis has been on providing capability and functionality
rather than. Answer: Security
◉ risk associated with use of LANs includes. Answer: Loss of data
and program integrity, Lack of current data protection, Exposure to
external activity, Virus and worm infection
◉ risk associated with use of LANs includes. Answer: Improper
disclosure of data, Violation of software licenses, Illegal access,
Internal user's sniffing, Internal user's spoofing, Destruction of the
logging and auditing data
◉ Commonly available network security administrative capabilities
include. Answer: Declaring ownership of programs, files and storage,
Limiting access to a read-only basis, Implementing record and file
locking to prevent simultaneous update, Enforcing user
,ID/password sign-on procedures, Using switches, Encrypting local
traffic using IPSec
◉ Network administration. Answer: Is often inadequate, providing
global access because of the limited administrative support available
when limited access is appropriate
◉ WLAN technologies. Answer: Conform to a variety of standards
and offer varying levels of security features
◉ The principal advantages of standards. Answer: Encourage mass
production and to allow products from multiple vendors to
interoperate
◉ The most useful standard used. Answer: Is the IEEE 802.11
standard.
◉ 802.11. Answer: Refers to a family of specifications for wireless
LAN technology.
◉ 802.11. Answer: Specifies an over-the-air interface between a
wireless client and a base station or between two wireless clients.
,◉ IEEE 802.11's Wired Equivalent Privacy (WEP) encryption.
Answer: Uses symmetric, private keys, which means the end
user's radio-based NIC and access point must have the same key
◉ WEP. Answer: Leads to periodic difficulties distributing new keys
to each NIC and keys remain unchanged on networks for extended
times.
◉ With static WEP keys. Answer: Several hacking tools easily break
through the relatively weak WEP encryption mechanisms.
◉ Because of the key reuse problem and other flaws. Answer: The
current standardized version of WEP does not offer
strong enough security for most corporate applications
◉ Newer security protocols such as 802.11i WPA2
and Wi-Fi Protected Access (WPA). Answer: Utilize public key
cryptography techniques to provide effective authentication and
encryption between users and access points
◉ A port. Answer: Is a logical connection.
◉ TCP/IP designating a port. Answer: Is the way a client program
specifies a particular server
, program on a computer in a network
◉ a port number. Answer: Is a way to identify the specific process to
which
an Internet or other network message is to be forwarded when it
arrives at a server
◉ For TCP, UDP and ICMP. Answer: A port number is a 16-bit integer
that is put in
the header attached to a unit of information then passed logically
between client and server transport layers and physically between
the transport layer and the Internet protocol layer and then
forwarded.
◉ Higher-level applications that use TCP/IP like. Answer: Web
protocol and hypertext transfer protocol (HTTP) use
ports with preassigned numbers
◉ well known ports. Answer: To which numbers have been assigned
by the Internet Assigned Numbers Authority (IANA)
◉ Allowable port numbers. Answer: Range from 0 to 65535
◉ are reserved for certain privileged services
