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 one type of cyberattack in which the attacker is a fake to access sensitive information or perform malicious acts, such as the theft of credit card numbers and 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 information stored in the database server behind. In an XSS, hackers inject malicious code into a website or website that is automatically executed by the victim’s browser without validation or encryption. The attack may hijack the victim’s session, display unauthorised images or text, or redirect users to a phishing website.
The best way to defend against cyber-attacks is to perform regular vulnerability scans, and to apply patches to your website, its web servers and any databases underlying. It is also recommended to establish an incident response plan to ensure that if an attack occurs it is quickly recognized and handled. You should also be able identify web-based attacks by being able to recognize warning signs such as site slowdowns or intermittent shut downs.
