Title: Endian IDS blocking Dropbox - how do I allow?
Post by: NickReplay on Tuesday 27 August 2013, 03:53:44 am
Hi,

Endian IDS is blocking Dropbox syncs/updates - how do I modify rules in order to allow this?

I'm thinking I need to set up Source NAT rules but I'm unsure how (I may be wrong too!)

Here is an example of an intrusion log:

snort[5026]: [1:2012647:3] ET POLICY Dropbox.com Offsite File Backup in Use [Classification: Potential Corporate Privacy Violation] [Priority: 1] {TCP} 192.168.0.78:57723 -> 108.160.163.50:80

Any help appreciated  8)

Nick

just read the alert description to know the number and type:  ...2012647....  ET POLICY .

Then:

- go to Services -> Intrusion Prevention
- edit "auto/emerging-policy.rules"
- see the rule numbers are ascendant. Go until 2012647:   "ET POLICY Dropbox.com Offsite File Backup in Use"
- unmark. Apply, and save.

that's all.
