Website defacement refers to unauthorized hacks on your web page or entire website; mutilating its structure partially or wholly. It may include insertion of potentially hazardous content, images, malicious code, or even deletion of the same. In some cases, instances like code injections can even put your customer's data in grave danger. A defaced web page can thus inflict severe damage to your business reputation and reliability. Enable security defacement monitoring to monitor website hack before it affects your customer.

Root Cause Standard Checks

Monitor website hacks via standard checks.

Site24x7 uses a baseline document object model (DOM) to analyze differences and perform defacement checks during subsequent polls. It morphs itself into a tampered link checker, which not only detects any tampered links in your DOM but also identifies where exactly those incorrect references locate in your HTML code. Below are the key aspects tested while performing a standard check:

  • Image defacement: Identify 'src' attribute changes with respect to the images present in the website page.
  • Script defacement: Identify changes with respect to the scripts embedded and detect any 'src' attribute change for the external script
  • Anchor defacement: Identify 'href' attribute changes in the anchor links present in the website page
  • Iframe defacement: Identify 'src' attribute changes in the iframe element and notify if there is a change in the domain name in the configured URL
  • Link defacement: Identify 'href' attribute changes in the link element of the website page
  • Text defacement: Identify any content changes with respect to the visible content in the rendered website page
  • Text modified percentage: Identify the percentage change in content against the base DOM content
  • Script modified percentage: Identify the percentage change in script against the base DOM view.

Whether you have a hugely popular blog or getting just a few visitors per day, you still want to make sure that your site is up and running all the time; and that no hackers have sprayed graffiti on your blog with the intention of defacing your website. In either of these emergency situations, you want to be notified immediately by email or an SMS on your mobile phone and Site24x7 will help you with just that.

Advanced web content integrity check and intelligent baselining.

A DOM for a web page lists each element that appears on the web page, including content, links, style specifications, scripts and more.

Using a headless browser, we detect changes to the DOM caused by execution of JavaScript and other dynamically loaded content. Site24x7 compares the current DOM to previously recorded DOM. It helps to identify any defacements and maintain content integrity.

During the monitor setup process, you can either manually set the monitor threshold configuration or enable auto detection of the content and script threshold value. In the auto mode, the monitoring engine will fetch each web page twice consecutively to discover the content and script modified threshold and will update it. The base web page content is automatically baselined for future monitoring.
