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 an example of a cyberattack, where an attacker impersonates another to gain access to sensitive information or perform malicious activities such as taking credit card numbers, or other personal information. Web attacks are what is web attack often characterized by SQLi (Structured Query Language Injection), XSS (cross-site scripting) and file upload attack.

In SQLi attack, hackers input customized Structured Query Language (SQL) commands into the field on a website or in a web app to steal private information stored on the backend database server. Similarly, in an XSS attack hackers inject malicious code into a website or web app that the victim’s browser automatically executes without verification or encryption. The attack could hijack the user’s session, display non-authorized images or texts, or redirect them to a fraudulent website.

The best way to guard against an attack via the internet is to run regular vulnerability scans and apply patches to your site as well as its web servers and any databases underneath. It is also a good idea to establish an incident response plan so that, should an attack occur, it can be quickly identified and responded to. Also, ensure that you know how to recognize the presence of a cyberattack by observing indicators like slowing of network speeds or intermittent website shutdowns.
