How do I blacklist file types for web applications?

In some cases, when scanning a website this option might come in handy since you can blacklist file types. If there are a lot of large files that can cause the scan to take a long time, you can choose to exclude them, and they will not be scanned by Holm Security WAS scanner.

When adding a new web application there are some extensions already excluded by default, the file types that are excluded by default and also shown in Security Center is: .zip, .tar, .bz2, .gz, .pdf, .ppt, .pptx, .doc, .docx, .odp, .woff, .woff2, .mp4, .mp3, .mov, .avi, .flv, .swf, .wmv, .wav, .rar, .7z, .deb, .rpm, .iso, .bin, .dmg, xls, .xlsx.

If you would like to remove or add more file types on a new web application, follow the steps in this article and it is described on step 8: https://support.holmsecurity.com/hc/en-us/articles/213291009

1. log in to Security Center.
