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 in which the attacker takes on the persona of another to gain access to sensitive information or perform malicious actions, like stealing credit card numbers or other personal data. Web attacks are typically characterized by SQLi (Structured Query Language Injection), XSS (cross-site scripting) and file upload attacks.
In SQLi hack, hackers insert custom 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 behind. In an XSS, hackers inject malicious code into a web application or website that is automatically executed by the victim’s browser with no verification or encryption. The attack can steal session information, display illegal text or images, or redirect the victim to a phishing website.
The best way to guard against an attack via the internet is to run regular vulnerability scans, and apply patches to your website as well as its web servers and any databases that are the basis for. It is also recommended to create an incident response plan to ensure that, should an attack occur it is quickly identified and responded to. Additionally, you should know how to detect the presence of a cyberattack by observing indications such as slowing down of the network or intermittent shutdowns of websites.
