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 information or perform malicious activities such as taking credit card numbers or other personal information. Web attacks are typically characterized by SQLi (Structured Query Language Injection), XSS (cross-site scripting) and file upload attacks.
In an SQLi attack hackers insert customized Structured Query Language commands into an app or website field to steal private information stored in the database server backend. In an XSS attack, hackers insert malicious code into a website or web app that the victim’s web browser automatically executes without verification or encoding. The attack can hijack the victim’s session, show unauthorized images or text, or redirect them to a phishing site.
The best way to guard against an attack via the internet is to run regular vulnerability scans, and to apply patches to your site as well as its web servers, and any databases that are underlying. It is also an excellent idea to develop an incident response plan so that in the event of an attack it is quickly recognized and handled. You should also be able to detect web attacks by recognizing warning signs like slowing down of the network and frequent website shut downs.
