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, where the attacker assumes the identity of someone else to access sensitive information or engage in illegal activities, like stealing credit card numbers and other http://neoerudition.net/top-3-best-free-vpn-for-deep-web personal data. The most common types of web attacks include Structured Query Language injection (SQLi), cross-site scripting (XSS) and attacks on file uploads.
In SQLi, hackers enter customized Structured Query Language (SQL) commands into fields on a website or in a web application to steal personal information stored on the database server that is backend. In an XSS attack hackers inject malicious code into websites or web apps that the victim’s browser executes automatically without confirmation or encoding. The attack can hijack session information, display unauthorised images or text or redirect the user to a phishing site.
The best way to guard against a web attack is to run regular vulnerability scans and apply patches to your website as well as its web servers and any underlying databases. It is also a good idea to create an incident response plan to ensure that in the event of an attack, it can be quickly discovered and addressed. Additionally, you should are aware of ways to spot an attack on your website by observing warning indicators such as slowdowns in the network or intermittent shutdowns of websites.
