Because web hosting services host websites belonging to their customers, online security is an important concern. When a customer agrees to use a web hosting service, they are relinquishing control of the security of their site to the company that is hosting the site. The level of security that a web hosting service offers is extremely important to a prospective customer and can be a major consideration when considering which provider a customer may choose.
Web hosting servers can be attacked by malicious users in different ways, including uploading malware or malicious code onto a hosted website. These attacks may be done for different reasons, including stealing credit card data, launching a Distributed Denial of Service Attack (DDoS) or spamming.
A customer needs to evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system. Most hosting providers provide Linux-based web hosting which offers a wide range of different software. A typical configuration for a Linux server is the LAMP platform: Linux, Apache, MySQL, and PHP/Perl/Python. The web hosting client may want to have other services, such as email for their business domain, databases or multimedia services.
A customer may also choose Windows as the hosting platform. The customer still can choose from Perl, PHP, Python and Ruby but may also use ASP .Net or Classic ASP. Web hosting packages often include a Web Content Management System, so the end-user does not have to worry about the more technical aspects.
