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 an example of a cyberattack where the attacker impersonates another person to gain access to sensitive information or carry out malicious activities such as stealing credit card numbers or other personal information. Web attacks are usually characterized by SQLi (Structured Query Language Injection), XSS (cross-site scripting) and file upload attack.
In a SQLi hack, hackers insert customized Structured Query Language (SQL) commands into fields on a website or a web-based application to steal private information stored on the database server behind. Similar to an XSS attack hackers inject malicious code into websites or web apps that the victim’s browser automatically executes without confirmation or encodes. The attack may steal session information, display unauthorised images or text, or redirect the victim to a fraudulent website.
The best way to guard against a web-based attack is to perform regular vulnerability scans, and apply patches to your website along with its web servers and any databases underneath. It’s also a good idea to establish an incident response plan to ensure that an attack can be detected quickly and dealt with. Also, ensure that you know how to recognize an attack on your website through warning indications such as slowing down of the network or intermittent website shutdowns.
