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 in which the attacker impersonates another person to gain access to sensitive information or perform malicious activities like the theft of 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 file upload attacks.

In an SQLi attack hackers input custom Structured Query Language commands into an app or website field to steal private data stored in the database server backend. In an XSS, hackers inject malicious code into a web application or website that is automatically executed by the victim’s browser, without verification or encoding. The attack can hijack session information, display illegal images or text or redirect the user to a fraudulent website.

The best way to defend against an attack via the internet is to perform regular vulnerability scans, and to apply patches to your website, its web servers and any databases that are the basis for. It is also a good idea to set up an incident response plan in order that should an attack occur it can be swiftly recognized and handled. Also, be sure to are aware of how to spot a web attack through warning indications such as slowing down of the network or intermittent shutdowns of websites.
