drive-by download
The use of malicious software to attack a computer by downloading harmful programs onto a computer, without the user's knowledge, while they are surfing a website.
Public Key Encryption
Used prevalently on the web, it allows for secure messages to be sent between parties without having to agree on, or share, a secret key. It uses an asymmetric encryption scheme in which the encryption key is made public, but the decryption key is kept private. uses two keys: one shared (or public) and one totally private as shown in Figure 8.6. The keys are mathematically related so that data encrypted with one key can be decrypted using only the other key. To send and receive messages, communicators first create separate pairs of private and public keys. The public key is kept in a directory, and the private key must be kept secret. The sender encrypts a message with the recipient's public key. On receiving the message, the recipient uses his or her private key to decrypt it.

Based on the priorities established by a network's operators, it decides whether a specific data packet can continue to its destination or should be blocked or delayed while more important traffic proceeds.
packet filtering
examines selected fields in the headers of data packets flowing back and forth between the trusted network and the Internet, examining individual packets in isolation
security
refers to the policies, procedures and technical measures used to prevent unauthorized access, alteration, theft or physical damage to information systems
application proxy filtering
examines the application content of packets; stops data packets originating outside the organization, inspects them, and passes a proxy to the other side of the firewall. If a user outside the company wants to communicate with a user inside the organization, the outside user first communicates with the proxy application, and the proxy application communicates with the firm's internal computer. Likewise, a computer user inside the organization goes through the proxy to talk with computers on the outside.
information systems audit
examines the firm's overall security environment as well as controls governing individual information systems
Business Continuity Planning
focuses on restoring business operations after a disaster strikes. The business continuity plan identifies critical business processes and determines action plans for handling mission-critical functions if systems go down. For example, Deutsche Bank, which provides investment banking and asset management services in 74 countries, has a well-developed business continuity plan that it continually updates and refines. It maintains full-time teams in Singapore, Hong Kong, Japan, India, and Australia to coordinate plans addressing loss of facilities, personnel, or critical systems so that the company can continue to operate when a catastrophic event occurs.
Social Engineering
hackers use their social skills to trick people into revealing access credentials or other valuable information
Analytical CRM
includes applications that analyze customer data generated by operational CRM applications to provide information for improving business performance.

is another protocol used for encrypting data flowing over the Internet, but it is limited to individual messages, whereas SSL and TLS are designed to establish a secure connection between two computers.
cross-selling
is the marketing of complementary products to customers. (For example, in financial services, a customer with a checking account might be sold a money market account or a home improvement loan.) CRM tools also help firms manage and execute marketing campaigns at all stages, from planning to determining the rate of success for each campaign.
Customer Relationship Management (CRM)
managing detailed information about individual customers and carefully managing customer touch points to maximize customer loyalty. a company-wide business strategy designed to optimize profitability, revenue, and customer satisfaction by focusing on highly defined and precise customer groups
bullwhip effect
occurs when distorted product-demand information ripples from one partner to the next throughout the supply chain. A slight rise in demand for an item might cause different members in the supply chain—distributors, manufacturers, suppliers, secondary suppliers (suppliers' suppliers), and tertiary suppliers (suppliers' suppliers' suppliers)—to stockpile inventory so each has enough just in case. These changes ripple throughout the supply chain, magnifying what started out as a small change from planned orders and creating excess inventory, production, warehousing, and shipping costs
Demand Planning
one of the most important and complex supply chain planing functions. Determines how much product a business needs to make to satisfy all of its customers' demands. JDA Software, SAP, and Oracle all offer supply chain management solutions.
Firewalls
prevent unauthorized users from accessing private networks A firewall is a combination of hardware and software that controls the flow of incoming and outgoing network traffic. It is generally placed between the organization's private internal networks and distrusted external networks, such as the Internet, although firewalls can also be used to protect one part of a company's network from the rest of the network.
antivirus software
prevents, detects, and removes malware, including computer viruses, computer worms, Trojan horses, spyware, and adware. However, most antivirus software is effective only against malware already known when the software was written. To remain effective, the antivirus software must be continually updated. Even then it is not always effective because some malware can evade antivirus detection.
Enterprise Systems
provide enterprise wide support and data access for a firm's operations and business processes. The database collects data from many divisions and departments in a firm and from a large number of key business processes in manufacturing and production, finance and accounting, sales and marketing, and human resources, making the data available for applications that support nearly all an organization's internal business activities. When new information is entered by one process, the information is made immediately available to other business processes
Stateful Inspection
provides additional security by determining whether packets are part of an ongoing dialogue between a sender and a receiver. It sets up state tables to track information over multiple packets. Packets are accepted or rejected based on whether they are part of an approved conversation or attempting to establish a legitimate connection.
