Over the past decade, millions of businesses have embraced web applications as an inexpensive way to build relationships and transactions with prospects and customers. But while they provide the opportunity for greater customer insight and efficiency, web applications also have vulnerabilities that can be exploited by cybercriminals. One of the most common and devastating of these is a web attack.
A web attack is a type of a cyberattack, where an attacker impersonates another to gain access to sensitive data or perform criminal activities, such as taking credit card numbers, or other personal data. The most common types of web attacks include Structured Query Language injection (SQLi) Cross-site scripting (XSS), and attacks on file uploads.
In an SQLi attack hackers enter customized Structured Query Language commands into a web application or website field to steal private information stored on the backend database server. In an XSS attack, hackers insert malicious code into websites or web apps that the victim’s browser executes without verification or encoding. The attack can hijack the user’s session, display non-authorized images or texts or redirect them to a phishing site.
The best way to protect against a cyber attack is to run regular vulnerability scans and apply patches to your website, its web servers, and any other databases that are underlying. It is also a good idea to establish an incident response plan to ensure that an attack can be identified quickly and dealt with. You should also be able identify web-based attacks by recognizing warning signs like site slowdowns or intermittent shut downs.
