Question

Question 1

You are a network administrator responsible for all network platforms and services. The Teta Company currently has only one building which houses its sole data center. The CIO indicates the company recently purchased the building next to existing building that will house 150 employees. Unfortunately, only a wired solution will work for providing access to the data network. What network requirements and recommendations would you make to the CIO that will allow the employees in the new building to access the company LAN?

Question 2

You are a network administrator responsible for all network platforms and services. The CIO has asked that two site networks be connected through a secure VPN connection. He indicates that cost is not an issue to support and manage this change. Which security option(s) for Internet transmission would you provide and state risks, if any, in your recommendation. Justify your answer.

Explanation / Answer

1:-

Wireless networks are becoming faster, more affordable and easier to adopt than ever. Growing small businesses that have adopted a wireless solution are already reporting immediate paybacks in higher productivity, flexible application mobility and greater worker satisfaction. Roughly 228,000 small businesses currently have remote access capabilities built into their networks for security monitoring and, according to America Marketing Institute, the number will double over the next 12 months.

A wireless infrastructure can make it easier to reconfigure your office space as your company grows and changes. Also, the total cost of a wireless local area network (LAN) is relatively inexpensive--it's become very affordable in the past few years, and prices continue to drop. When you take into account productivity gains, both inside the office and at public "hot spots," going wireless is an obvious choice, especially when compared to the cost of running a Cat 5 network LAN cable throughout a building.

you must secure your wireless network. Unlike a wired network, a wireless LAN is open to the public if you don’t lock it down. You don’t want your network turned into a hotspot like you find at Starbucks. Many wireless routers include network security features, including a firewall and a virtual private network (VPN). For maximum security, choose one that also offers intrusion prevention and content filtering.

WAPs offer security features, too, to help control who can jump onto your wireless network, including data encryption, access control lists (ACLs), and address filtering. You can also use WAPs to create virtual LANs (VLANs) to segment access for guest users

A wireless network simplifies connecting employees to the Internet while giving them more flexibility to work the way they need to, on any wireless device, from anywhere in the office. Because you don’t have to string cables in a wireless network, installation is quick and it allows you to easily expand you wired network and add new users.

2:-Web site encryption

Organizations that use the Web to collect and transmit sensitive data to customers or other organizations need to secure their Web site. The general standard is the use of secure socket layers (SSL), which encrypts data transmitted via a Web site.

Upon opening an Internet browser, an open or closed lock appears in the lower right hand corner of the Web site.

If the lock is closed, it means the data transmitted over the Web site is secure, generally by SSL. This allows the transmission and collection of private data over a Web site, without worrying about a hacker accessing it.

There is no such thing as security without risks, but the use of SSL and secure Web sites when transmitting data significantly reduces the risk of it being inappropriately intercepted. Secure Web sites can be established by using internal Web analysts/programmers or working with a vendor who has expertise in creating an appealing and secure Web presence.
