Website security is important to all users, no matter the size of the site. A compromised site is useful to a criminal who may be clever enough to use it for any number of purposes. Automated scanning tools search for vulnerable websites, hence it is not precise to insist that a little site will avoid attention. The fine news is that these attackers are looking for easy targets, users who have paid minimal or no attention to their websites security. With watchfulness of the most important issues and a proper amount of care, most potential problems can be avoided.
Shared servers vs. dedicated servers and virtual machines
The most reasonable web hosting service is hosting on shared server. This means that the clients do not have their own dedicated server, but that they share the space on a server with other users. Any of these clients can upload malicious code to the server, either through malicious intent or because their own site has been compromised. All new customers who use that server are later put at risk. A more safe option is the virtual server. This emulates an entire operating server, and for software purposes, each client has roughly their own independent server. They are yet physically in the same machine but are completely separated from each other by the virtual machine emulator. These are offered at rates as low as $50 per month, and servers dedicated to a single client are around $100/month range. A corporation or individual who hosts their own web server onsite will obviously avoid any potential shared assist problems, but are subject to even worse problems unless they are very skillful in security matters and are meticulous on applying updates.
Windows vs. Linux servers
Linux has gained a high reputation as a stable and safe functioning system, and it is appealing to endure that the use of a Linux host will guarantee a secure website. The version of Windows operating system that runs on a server is different from that of a home computer. The decision on which operating system to use , mainly depends on the use of the site and the services it will host.The riskiest applications are likely to be services run upon the server, such as PHP and SQL, and not the server itself.
The most important website security risk is an attack on an SQL database. This occurs when an invader sends a deliberately wrong SQL query in an attempt to crack the database. If the attack is successful it can result on the attacker taken complete control of the server and use it for malicious reasons. Attacks are frequently successful on servers running software versions that are long out-of-date.
Planning for security
Some websites are easy and have little or no important data and do not need complicated security measure ways for protecting this data. However, sites with user management and sensitive information stored in databases are more prove to attacks and security measures should be planned and implement by professional to avoid stealing of that data (credit card information etc.) . Take time during website design to identify what the sites potential threats and vulnerabilities might.Proper authentication and session supervision are crucial, but it is with important to validate all incoming and outgoing data to ensure that it is what it is claimed to be. When portions of the site are protected by admission controls, make certain that they are always enforced, and that users cannot enter through a browser’s history link.
