Making an internet site secure is vital to sites in which currency will change hands. It is also important to prevent people who may have a bone to pick or from hackers that are bored and try to knock websites down for kicks. There are a lot of ways to do this including buying a domain that already has integrated security. These domains are more expensive, but if the developer is short on time or security integration skills, this is the way to go. There are other techniques, but they would need a little technical no how and the time and resources to implement them.
More than one type of website exists so security will depend on the type of site and what kind of pages the site is made of, dynamic or static. For static sites, their security is 90% dependent on the server settings and modernity of the software used in hosting it. Keeping the software up to date and the server maintained will kill off almost all the security risks of these static pages. The other small percentages of threats arise from theft of authorization data. It is vital to secure authorization data offsite and encrypt it to prevent malicious access.
Sites containing dynamic content and third party web apps should always keep the apps as up to date as possible. The site becomes more vulnerable to unwanted behavior is the content comes from unknown or rare. Unknown applications usually have destitute security and/or come from questionable development. If the website was designed for pay then the security depends entirely on the skill and techniques used by the developers to make it secure.
Regardless of format and content, it is important to make sure that the following components are patched and secured. The server, the web app server, the database server, the proxy server, and the web applications are written in languages like ASP, ASP.NET/ Perl, PHP, Python, JSP, and Java all need to be updated and locked down. For sites that use logins and passwords, do not store the information as cookies. If they are available to the host to access, anyone clever enough to access the main hard drive can access all the account ids and passwords. But keeping the passwords in a database is safer. The cookies can be tracked and located to where they are stored where as a database will have fewer incoming and outgoing connections, hence a lower profile for hackers and thieves.
Security on a website can be very technical and difficult to implement effectively. If the site handles monetary transactions, it is exceedingly important to secure it. For hackers whose sole obligation is to obtain other people’s money illegally, monetary sites are an attractive target. There is an absolute need for no access to account or databases holding data for the site. Spend the extra money to have the site secured by security specialist and avoid the risk of losing everything because some wonder boy found a backdoor to your server.
