Reference / correct answer:

Use a complex password for a router's administrative console.

Configure access list entries to prevent unauthorized connections and traffic routing.

Keep routers updated with the latest security patches.

The following are the valid steps for securing routers and devices:

Configure access list entries to prevent unauthorized connections and traffic routing. Use a complex password for a router's administrative console.

Keep routers in locked rooms.

Keep routers updated with the latest security patches.

Use monitoring an equipment to protect routers and devices.

Router is a device that routes data packets between computers in different networks. It is used to connect multiple networks, and it determines the path to be taken by each data packet to its destination computer. Router maintains a routing table of the available routes and their conditions. By using this information, along with distance and cost algorithms, the router determines the best path to be taken by the data packets to the destination computer. A router can connect dissimilar networks, such as Ethernet, FDDI, and Token Ring, and route data packets among them. Routers operate at the network layer (layer 3) of the Open Systems Interconnection (OSI) model.

A security patch is a program that eliminates a vulnerability exploited by hackers.

Question 12

Which of the following is the primary international body for fostering cooperative standards for telecommunications equipment and systems?

Select an option, then click Submit answer.

○
ICANN
○
IEEE
○
NIST
○
CCITT

Reference / correct answer:

CCITT

CCITT is the primary international body for fostering cooperative standards for telecommunications equipment and systems. It is now known as the ITU-T (for Telecommunication Standardization Sector of the International Telecommunications Union). The ITU-T mission is to ensure the efficient and timely production of standards covering all fields of telecommunications on a worldwide basis, as well as defining tariff and accounting principles for international telecommunication services.

Answer option A is incorrect. Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization that oversees the allocation of IP addresses, management of the DNS infrastructure, protocol parameter assignment, and root server system management.

Answer option B is incorrect. The Institute of Electrical and Electronic Engineers (IEEE) is a society of technical professionals. It promotes the development and application of electro-technology and allied sciences. IEEE develops communications and network standards, among other activities. The organization publishes number of journals, has many local chapters, and societies in specialized areas. Answer option C is incorrect. The National Institute of Standards and Technology (NIST), known between 1901 and 1988 as the National Bureau of Standards (NBS), is a measurement standards laboratory which is a non-regulatory agency of the United States Department of Commerce. The institute's official mission is as follows: To promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve quality of life.

NIST had an operating budget for fiscal year 2007 (October 1, 2006-September 30, 2007) of about $843.3 million. NIST's 2009 budget was $992 million, but it also received $610 million as part of the American Recovery and Reinvestment Act. NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel. About 1,800 NIST associates (guest researchers and engineers from American companies and foreign nations) complement the staff. In addition, NIST partners with 1,400 manufacturing specialists and staff at nearly 350 affiliated centers around the country.
