How to Prevent Cross-site Scripting (XSS) Attacks?
Cross-site scripting (XSS) attacks are a common tool of internet thieves who introduce malicious scripts into order to get access to a private database or server. Once inside, a hacker can steal private customer information, such as social security and credit card numbers. Many companies have lost clients and as well as their merchant service accounts because they failed to take the necessary steps to protect their customers from XSS attacks.
Where to begin? The only effective way to prevent an attack from a hacker is to make certain that your system is not vulnerable to XSS attacks. It is also important to know which tricks and stratagems these thieves employ. Let us take a moment to review them.
The easiest and most reliable way for a hacker to gain access to a secure site is to send an email to a current customer that includes an attractive offer. This is commonly called phishing, and if the customer bites by clinking on the link, the hacker can monitor his movements, including when he enters his user ID and password. At that point, the thief will have all he needs to enter a secure system and retrieve whatever confidential information he wants.
How can these types of attacks be prevented? There are five reliable steps. First, it is important to disable any scripting that is not needed. This will help reduce the likelihood that malicious scripting will be introduced into your system. Next, never trust link to other sites that are found in emails. They may contain harmful codes. Never follow links to personal or business pages unless you know them. Always access directly, never through a third-party site. And last but not least, obtain an accurate list of the XSS attacks and steer clear of the websites or messages boards that reported them.
