1. THE E-COMMERCE SECURITY ENVIRONMENT

1.1. DIMENSIONS OF E-COMMERCE SECURITY

1.1.1. Integrity

1.1.1.1. The ability to ensure that information being displayed on a Web site or transmitted or received over the Internet has not been altered in any way by an unauthorized party

1.1.2. Nonrepudiation

1.1.2.1. The ability to ensure that e-commerce participants do not deny (i.e., repudiate) their online actions

1.1.3. Authenticity

1.1.3.1. The ability to identify the identity of a person or entity with whom you are dealing on the Internet

1.1.4. Confidentiality

1.1.4.1. The ability to ensure that messages and data are available only to those who are authorized to view them

1.1.5. Privacy

1.1.5.1. The ability to control the use of information about oneself

1.1.6. Availability

1.1.6.1. The ability to ensure that an e-commerce site continues to function as intended

1.2. THE TENSION BETWEEN SECURITY AND OTHER VALUES

1.2.1. Ease of Use

1.2.1.1. The more security measures added to an e-commerce site, the more difficult it is to use and the slower the site becomes

1.2.1.2. Digital security is purchased at the price of slowing down processors and adding significantly to data storage demands on storage devices

1.2.2. Public Safety and the Criminal Uses of the Internet

1.2.2.1. Encrypted files sent via e-mail were used by Ramzi Yousef

1.2.2.1.1. to hide plans for bombing 11 U.S. airliners

1.2.2.1.2. the Internet was also used to plan and coordinate the subsequent attacks

1.2.2.2. The case of Umar Farouk Abdulmutallab

1.2.2.2.1. make effective use of the Internet to radicalize, recruit, train, and coordinate youthful terrorists

1.2.2.2.2. allegedly attempted to blow up an American airliner

1.2.2.3. National Security Administration contractor Edward Snowden

1.2.2.3.1. release of classified NSA documents that revealed that the NSA had obtained access to the servers

1.2.2.3.2. NSA analysts have been searching e-mail, online chats, and browsing histories of U.S. citizens without any court approval

1.2.2.4. The U.S. government

1.2.2.4.1. informal tapping of telegraph wires

1.2.2.4.2. the first police wiretaps of local telephone systems were in place

1.3. Cyber crime against e-commerce sites is dynamic and changing all the time, with new risks appearing often

1.3.1. The amount of losses to businesses appears to be significant but stable

1.3.2. may represent a declining percentage of overall sales

1.3.3. firms have invested in security measures to protect against the simplest crimes

1.4. E-COMMERCE SECURITY

1.4.1. New technologies are available and should be used

1.4.1.1. These technologies by themselves do not solve the problem

1.4.1.2. Organizational policies and procedures are required to ensure the technologies are not subverted

1.4.1.3. Industry standards and government laws are required to enforce payment mechanisms

1.4.1.4. Investigate and prosecute violators of laws designed to protect the transfer of property in commercial transactions

2. TECHNOLOGY SOLUTION

2.1. PROTECTING INTERNET COMMUNICATIONS

2.1.1. Encryption

2.1.1.1. the process of transforming plain text or data into cipher text that cannot be read by anyone other than the sender and the receiver

2.1.1.1.1. purpose of encryption is (a) to secure stored information and (b) to secure information transmission

2.1.2. Symmetric Key Encryption

2.1.2.1. both the sender and the receiver use the same key to encrypt and decrypt the message

2.1.3. Public Key Encryption

2.1.3.1. The mathematical algorithms used to produce the keys are one-way functions. A one-way irreversible mathematical function is one in which, once the algorithm is applied, the input cannot be subsequently derived from the output.

2.1.3.2. based on the idea of irreversible mathematical functions. The keys are sufficiently long (128, 256, and 512 bits) that it would take enormous computing power to derive one key from the other using the largest and fastest computers available

2.1.3.3. two mathematically related digital keys are used: a public key and a private key. The private key is kept secret by the owner, and the public key is widely disseminated. Both keys can be used to encrypt and decrypt a message. However, once the keys are used to encrypt a message, that same key cannot be used to unencrypt the message

2.1.4. Public Key Encryption Using Digital Signatures and Hash Digests

2.1.4.1. digital signature (e-signature) “signed” cipher text that can be sent over the Internet

2.1.4.2. hash function an algorithm that produces a fixed-length number called a hash or message digest

2.1.5. Digital Envelopes

2.1.5.1. a technique that uses symmetric encryption for large documents, but public key encryption to encrypt and send the symmetric key

2.1.6. Digital Certificates and Public Key Infrastructure (PKI)

2.1.6.1. a digital document issued by a certification authority that contains the name of the subject or company, the subject’s public key, a digital certificate serial number, an expiration date, an issuance date, the digital signature of the certification authority, and other identifying information

2.1.6.2. certification authority (CA) a trusted third party that issues digital certificates

2.1.6.3. public key infrastructure (PKI) - CAs and digital certificate procedures that are accepted by all parties

2.1.7. Limitations to Encryption Solutions

2.1.7.1. PKI applies mainly to protecting messages in transit on the Internet and is not effective against insiders—employees—who have legitimate access to corporate systems including customer information.

2.1.7.2. Most e-commerce sites do not store customer information in encrypted form

2.1.7.3. no guarantee the person using your computer—and your private key—is really you

2.2.2. Virtual Private Networks (VPNs)

2.2.2.1. allows remote users to securely access internal networks via the Internet, using the Point-to-Point Tunneling Protocol (PPTP)

2.2.2.2. primary use of VPNs is to establish secure communications among business partners—larger suppliers or customers, and employees working remotely

2.2.2.3. Using the Internet and VPN as the connection method significantly reduces the cost of secure communications

2.2.3. Wireless (Wi-Fi) Networks

2.2.3.1. Wi-Fi networks used a security standard called Wired Equivalent Privacy (WEP) to encrypt information

2.2.3.1.1. WEP was very weak, and easy for hackers to crack

2.2.3.2. Wi-Fi Protected Access (WPA) was developed that provided a higher standard of protection, but this too soon became vulnerable to intrusion

2.2.3.3. the current standard is WPA2

2.2.3.3.1. WPA2 - wireless security standard that uses the AES algorithm for encryption and CCMP, a more advanced authentication code protocol

2.3. PROTECTING NETWORKS

2.3.1. Firewalls

2.3.1.1. refers to either hardware or software that filters communication packets and prevents some packets from entering the network based on a security policy

2.3.1.2. controls traffic to and from servers and clients, forbidding communications from untrustworthy sources, and allowing other communications from trusted sources to proceed

2.3.1.3. can filter traffic based on packet attributes such as source IP address, destination port or IP address, type of service (such as WWW or HTTP), the domain name of the source, and many other dimensions

2.3.1.4. increasing use of firewalls by home and business Internet users has greatly reduced the effectiveness of attacks, and forced hackers to focus more on e-mail attachments to distribute worms and viruses

2.3.2. Proxy Servers

2.3.2.1. software server that handles all communications originating from or being sent to the Internet, acting as a spokesperson or bodyguard for the organization

2.3.2.2. sometimes called dual-home systems because they have two network interfaces

2.3.2.3. To internal computers, a proxy server is known as the gateway, while to external computers it is known as a mail server or numeric address.

2.3.2.4. . The proxy server validates the user and the nature of the request, and then sends the request onto the Internet

2.3.2.5. improve Web performance by storing frequently requested Web pages locally, reducing upload times, and hiding the internal network’s address

2.3.3. Intrusion Detection and Prevention Systems

2.3.3.1. IDS - examines network traffic, watching to see if it matches certain patterns or preconfigured rules indicative of an attack

2.3.3.2. IPS - has all the functionality of an IDS, with the additional ability to take steps to prevent and block suspicious activities

2.4. PROTECTING SERVERS AND CLIENTS

2.4.1. Operating System Security Enhancements

2.4.1.1. most obvious way to protect servers and clients is to take advantage of automatic computer security upgrades

2.4.1.2. e. The most common known worms and viruses can be prevented by simply keeping your server and client operating systems and applications up to date

2.4.2. Anti-Virus Software

2.4.2.1. The easiest and least-expensive way to prevent threats to system integrity is to install anti-virus software

2.4.2.2. identify and eradicate the most common types of malicious code as they enter a computer, as well as destroy those already lurking on a hard drive

2.4.2.3. Anti-virus suite packages and stand-alone programs are available to eliminate intruders such as bot programs, adware, and other security risks
