What is Web Attack?

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 the attacker impersonates another person to gain access to sensitive data or perform malicious activities such as stealing credit card numbers or other personal data. Web attacks are usually characterized by SQLi (Structured Query Language Injection), XSS (cross-site scripting) and file upload attacks.

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

The best method to protect against cyber-attacks is to perform regular vulnerability scans, and to apply patches to your website, its web servers and any databases the basis for. It is also an excellent idea to create an incident response plan in order that if an attack occurs it can be quickly detected and dealt with. You should also be able to detect attacks on websites by recognizing warning signs like site slowdowns or intermittent shut downs.
