You can specify a black list for Collaboration. Collaboration is the platform for cooperation across teams. With Collaboration, information can be exchanged faster, knowledge can be shared, and cooperation across borders is improved. Collaboration is a forum in which users can mention any URL in posts. It is therefore more appropriate to define a black list.
A white list or black list is a positive or negative list with which systems can be protected. White lists and black lists pursue opposing strategies.
A white list contains all permitted URLs. A blacklist, on the other hand, specifically excludes URLs.
Procedure
To start ACC under a Windows operating system click Start > All Programs > ARIS > Administration > Start ARIS Cloud Controller. If you have changed agent user credentials you must enter the user name and/or the password.
To start ACC under a Linux operating system, execute the acc10.sh shell script instead.
Enter reconfigure ecp_<s, m, or l> "JAVA-Dcom.aris.umc.blacklist.url.regex.pattern"="<comma-separated list of regular expressions>".
Example
If you want to block yahoo.com, use the following regular expression:
(http(s)?://)?([\\w-]+\\.)+[\\w-]+[\\yahoo\\.com]+(/[/?%&=]*)?
You have specified a black list for ARIS Administration.
You can remove the black list again. To do so, proceed as described above and configure reconfigure ecp_m -"ecp.blacklist.url.regex.pattern".
