How many types of threats in e commerce?

Answer 1

Client/ Server security mechanism provides authorization methods which ensure that only valid users can access information on client or server machines. The client server security use ethod password, encryption, firewalls etc.

1. Client Threats-

Reasons of client threats are malicious data (virus, logic bomb, worm)etc. This type of code associated with stand alone personal computers but it can also affect networks. The malicious code are-

- Virus: A virus is a self replicating programs which main purpose is to propagate itself to as many different places as possible. A virus propagate itself by modifying another program to include itself. A virus can propagate itself by an act of a user of the system in which it exist. Virus program do not differ any other computer programs. They are created using common programming tools. A virus main concern is to remain hidden from the computer user and from various antivirus programs.

- Trojan Horse: It includes some unexpected function in the program which are designed for special purpose.

- Worm: Worm is a self contained program which create itself a copy of program and execute it. It does not require any host program. Worm creates self contained program for network services. To reduce above malicious code client must detect data and that process which are transfer among host and client.

2. Server threats-

Threats to Server have following reasons such as-

- Modification on server data

- Modification of incoming data

- Bugs in server software

Compare to client, servers are much affected by affected by attack because-

- Hackers use UNIX programs to find out account name and then try to unauthorized access it.

- By using eaves dropping system any hacker may use authorized user name and its password by tracking it.

Servers also affected by delay of services, denial process (service over loading and message flooding). To avoid these threats the server security methods such as firewalls, encryption use.

4.)Identity theft:

This is not a common problem in E-Commerce but sometimes it may incur heavy loss of money and may lead to bad stature of the individual or a company. Here a person may hack someone else's account and may communicate with the other party and can again some sensitive information of both the parties.

5.)Man-in-the-Middle attack:

In this type of attack a third party may pose as both the legitimate parties and both the parties may feel that they are communicating with each other and in the process they may transact sensitive information

6.)Server threats:

Hackers may hack the server or host system and can steal important information and can give a devastating set back.
