Cisco Mobility Express was designed to offer wireless services to small businesses in a form factor similar to the lightweight architecture. It is not the full Lightweight Access Point Protocol (LWAPP) but rather a subset of LWAPP functionality. This means that although the 521 AP runs the subset of LWAPP, it cannot communicate with enterprise controllers. The Cisco Mobility Express solution delivers best-in-class wireless capabilities that until recently had been reserved for enterprises. The solution is sold at a premium accessible to small to medium-sized business (SMB) customers who are seeking to gain a competitive edge without having to compromise between price and sophistication. SMBs now have an alternative to consumer-grade products and can benefit from the latest enterprise-class services available over Wi-Fi. Also of noteworthiness is that Linksys offers an upgrade program for businesses that want to get enterprise-class devices into the network. This is a key type of...
ADSL will play a crucial role over the next decade or more as telephone companies enter new markets for delivering information in video and multimedia formats. New broadband cabling will take decades to reach all prospective subscribers. Success of these new services will depend on reaching as many subscribers as possible during the first few years. By bringing movies, television, video catalogs, remote CD-ROMs, corporate LANs, and the Internet into homes and small businesses, ADSL will make these markets viable and profitable for telephone companies and application suppliers alike.
In April 2007, Cisco introduced a new solution designed to bring the power of Unified Communications to small businesses. Introduced under the name Smart Business Communications System (SBCS), the UC500 product family makes up a fully featured and economical solution that provides voice, data, video, security, and wireless in a manner that is simple, affordable, manageable, and complete. Unified Communications brings the capacity for business transformation, and the ramifications are immense. For the small business, introducing the power of Unified Communications means that it can compete with large enterprises. For small businesses, Unified Communications tools can level the business playing field however, to be feasible, those tools have to be simple, affordable, manageable, and complete. It is here where the SBCS suite hits its mark.
The Cisco 1600 series, with modular features, is optimized to meet the needs of small remote offices. Cisco 1600 series routers connect small offices with Ethernet LANs to the Internet and to company intranets using several WAN technologies ISDN, asynchronous serial, and synchronous serial, including Frame Relay, leased lines, Switched 56, SMDS, and X.25. Optional WAN interface cards add flexibility and growth opportunities. The Cisco 1600 series routers are part of the Cisco Networked Office Stack, a flexible suite of products that enables small businesses to easily take advantage of the Internet to attract new customers, improve communications, lower ongoing expenses, and increase productivity. Table E-6 lists the products in the 1600 series.
The Cisco 1800 series of ISRs is designed for small businesses and smaller enterprise branch offices. These routers are designed for connectivity via cable modem DSL, Metro Ethernet, and wireless technologies. Table 3-4 contrasts some of the features available in the Cisco 1800 and 1841 series of ISRs.
As previously discussed in this chapter, the Cisco Unified CME is an entry-level VoIP solution that runs on Cisco IOS Software routers. It is designed for small businesses and autonomous small enterprise branch offices. CME enables you to provide voice, data, and IP telephony services on a single platform. Because it is an integrated solution within Cisco IOS Software routers, all the best practices of router security that you learned in Chapter 2 apply when securing the Cisco Unified CME solution. These best practices include the following
Internet marketing uses World Wide Web sites and other means (such as e-mail and File Transfer Protocol FTP sites) to market companies. The Internet has been called the great equalizer between giant corporations and small businesses. With Internet marketing, customers do not know how small or large a company is because Web sites focus on the product or service. Web sites can also help small- and medium-sized businesses build stronger customer and partner relationships by providing easy access to company information from anywhere and at any time.
The CCIE certification fell short of the goal of helping to certify resellers and other partners as the number of partners increased to include some smaller integrators that were satisfying the medium and small business markets. Many smaller resellers that provided turnkey solutions for small businesses were not able to attain any degree of discount because of their size. Cisco, however, needed their skills to continue to capture the small business market, which is one of the largest markets in the internetworking arena today.
The UC520 chassis, also known as the UC500 Series for Small Business, delivers tremendous value to small businesses right out of the box. The engineering might of an enterprise business is delivered to the small business by simply attaching the UC520 chassis to the small business's network. Many of the features found in enterprise class network equipment and the engineering know-how of large IT organizations have been rolled into this product out of the box. Starting with the system's delivery of an industry best-practice security and QoS configuration, and delivering all the way to providing basic dial tone without any configuration, the UC520 is a powerhouse.
When Cisco first entered the IP telephony space, it did so with its flagship CallManager product line. CallManager was a dedicated server or servers that was a custom fit for medium to large businesses deploying thousands of phones at a single site or multiple locations. Although CallManager (now known as Cisco Unified Communications Manager) provided a cost-effective solution for these larger businesses, the startup price was far beyond the range that was affordable by small businesses.
The Cisco Micro Webserver is offered as part of the Cisco Networked Office Stack. This is a flexible suite of products that enables small businesses to easily take advantage of the Internet to attract new customers, improve communications, lower ongoing expenses, and increase productivity.
Small networks, such as those deployed by small businesses, might be run by a single person or network administrator as a part-time job. In those cases, how to run the network isn't much of an organizational issue The network administrator is in charge, and if problems arise that the network administrator cannot solve (or if the network administrator is out sick), customer support by a third party, by the equipment vendor, or by a consultant is only a phone call away. In addition, many communication services such as web hosting or voice services are simply purchased from an outside service provider.
As indicated earlier, a single system is generally not sufficient to manage a network. Instead, the work needs to be distributed. Let's look at a real-life analogy. Consider a person who owns and runs a small business. As the business grows, the business owner might no longer be able to manage the business single-handedly. So she gets help. She still wants to be in charge of running the overall business, but she distributes certain tasks across her people. Eventually, she starts building an organizational hierarchy.
A LAN is a common type of network found in home offices, small businesses, and large enterprises. Understanding how a LAN functions, including network components, frames, Ethernet addresses, and operational characteristics, is important for an overall knowledge of networking technologies.
SecureMe has grown dramatically and now has a new headquarters office in New York. It has also acquired the small company described in Chapter 13, Deploying and Troubleshooting NAC in Small Businesses. That acquisition has become a small branch office in the Tampa, Florida, area. The SecureMe Chicago office described in Chapter 14, Deploying and Troubleshooting NAC in Medium-Size Enterprises, has become a regional office. Figure 15-1 illustrates a high-level overview of the new infrastructure.
However, a piece is missing from the business equation. As noted previously, the business of business in the twenty-first century is intellectual property, or the creation of good ideas. As Peter Drucker (Innovation and Entrepreneurship, 1985) noted, intellectual property can be thought of as a direct replacement for capital, money, and labor. As the dot-com has illustrated, small companies armed with good ideas can outperform much larger companies.
The 3005 is for small businesses with a small-bandwidth Internet connection. The 3005 supports up to 4 Mbps VPN performance, so it's ideal for sites that have a T1, cable modem, or DSL connection. You can have up to 200 IPsec remote access sessions terminated on the 3005 or 50 WebVPN sessions with Version 4.7 of the operating system installed.
A lot of business administration literature discusses different business management approaches. Actually, scaling the task to manage networks is not all that different from scaling the task to manage other business functions, such as managing people in an organization. Therefore, let us for a moment take a look at how organizations are managed in real life. Going back to the example of the small business owner, after she has received help, what does she ask the help to do How does she manage her subordinates Maybe she is not really willing to relinquish control and becomes a micromanager. Eventually, this is likely to create problems. For one thing, it might cause job dissatisfaction with her subordinates, although in the case of management systems this is admittedly not a problem. However, it might simply not be a very efficient way to do things. Ultimately, the subordinates need to be leveraged better by adjusting the approach to management the style or philosophy according to which...
Reconsider the case study at the beginning of the chapter. Duddleduddle is a large hospital with several sites in the city. Although the sites connect to a centralized patient and administration database, the hospital has fought for local autonomy based on the specialization of the site and the fact that it is its own business unit. An IT group manages the central administration and oversees the other sites. The chief information officer (CIO) who ran this group and the overall network has left because of political wrangling. The new CIO, recently appointed, is attempting to sort out the mess.
Specific to your own business organization. It can, however, outline some common strategies that you can use when configuring network infrastructure devices to make sure that access to the areas of your network and its devices is granted only when needed by authorized sources.
IPv6 enables easier support and maintenance of service provider networks than previous versions. The large address space improves the usage of online support systems and enables the inexpensive provision of address space to end users. Many service providers in Europe, Asia, and the United States are currently working on providing IPv6 services to enterprises and small businesses. This chapter includes several IPv6 security topics. It also provides a comparison with IPv4 from a threat and mitigation perspective.
A network is a connected collection of devices that can communicate with each other. Networks in homes, small businesses, or large enterprises allow users to share resources such as data and applications (e-mail, web access, messaging, collaboration, and databases), peripherals, storage devices, and backup devices. Networks carry data (or data packets) following rules and standards called protocols, each with its own specialized function. Networks can be evaluated in terms of both performance and structure, using measures such as speed, cost, security, availability, scalability, reliability, and topology.

Firewall technologies have undergone substantial changes since their entry into the marketplace in the early 1990s. These first firewalls were simple packet-filtering devices. Since those days, firewalls have become much more sophisticated in their filtering features, adding such capabilities as stateful filtering, Virtual Private Networks (VPNs), intrusion-detection systems (IDS), multicast routing, connection authentication, Dynamic Host Configuration Protocol (DHCP) services, and many others. One of the driving forces of these enhancements, besides vendor competition, was the explosion of Internet usage in the mid- to late 1990s. This huge growth brought many beneficial services to individuals and companies, but it also brought its own set of problems, including hacking, break-ins, and other types of undesirable actions. Given these problems and the need to protect a company's assets, firewalls have become a common technology for not only enterprise companies, but also small...
