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 pretends to be another person to gain access to sensitive data or perform malicious activities like taking credit card numbers, or other personal information. Common types of attacks on the web include Structured Query Language injection (SQLi) and cross-site scripting (XSS), and attacks on file uploads.
In a SQLi, hackers enter customized Structured Query Language (SQL) commands into the field on a website or in a web app to steal private information stored on the database server that is backend. In an XSS, hackers inject malicious code into a website or website, which is then executed by the victim’s browser with no validation or encoded. The attack can take over the victim’s session, show unauthorized images or text or redirect them to a phishing site.
The best way to protect against a web-based attack is to perform regular vulnerability scans and apply patches to your website as well as its web servers, and any databases that are involved in the attack. It is also a great idea to devise an incident response plan to ensure that any attack can be detected quickly and addressed. You should also be able to identify attacks on websites by recognizing warning signs such as slowing of networks and intermittent website shutdowns.
