Ecommerce communication has become easy and fast because of the advance of the Internet.Also, threat to the ecommerce system has increased because of the Internet’s unstructured nature.Here are some common security issues.

Some of the common problems are denial of service (DOS) to prevent the authorized customers from accessing the websites, gaining access to sensitive information from the website, destroying the sensitive information, altering important information and contents in the website, and directing the customers to another website.Hence, enough ecommerce security control standards should be introduced to reduce the risk in the ecommerce system.

If the website of an individual is hacked, it can have significant impact on the business that is running on ecommerce systems.The possible impact on the ecommerce security could be: high financial loss due to fraud or litigation activities, other financial loss due to unwelcome publicity, possible criminal charges due to any breach in the data protection or regulation in the ecommerce systems, and loss of customer market due to DOS attack.

Here are few methods to reduce the risk in the ecommerce system.Authentication: This method identifies the visitors who access the website.The steps followed are: creating new username and password for all registered users, making a two factor verification system for the registered members, and reading the member’s unique physical attribute.Access Control: In this method, access for all users is confined according to their usage.Therefore, it restricts the access of sensitive data, and thus reduces the risk.

Encryption: This technique uses technologies such as secure socket layer (SSL) and virtual private network (VPN) to secure sensitive data that are transmitted or shown on the individual’s website.Firewall: This can be either software or hardware that can be used to prevent the hackers or viruses from entering server, computer systems, or on the network.Firewall can be used at the network level, to provide safety measures for multiple computers across the networks.If used on the personal computers, it protects only the system where it is set up.

Intrusion Detection System (IDS): This technique screens all the inbound and outbound activities happening on the network level.Also, this method finds out all the illegal access gain on the system or the network. It also notifies the suspected threat or risk via email or alarm.Despite this control measures, a continual awareness is an important component of any security system.
