Catching Landspeed Violations in Relativity

The Tip of the Night for May 28, 2021 discussed tracking 'landspeed' violations, when the same user logins from two different locations which are far apart. Relativity's Security Center can help an admin monitor such suspicious logins. The Security Center generates a map showing all of the logins that have taken place for the past 7 days.

You can drill down to more geographically specific information, by clicking on any circle. The circles will be color coded in order to show the security method used for the login. So password only logins will be in red circles, and logins using 2FA will be in green.

At the lowest level, the map will show the user login and IP address.

Text Field Sizes in Relativity

Fields in Relativity can be any one of several types including date, whole number, decimal, currency, single choice, multiple choice, single object, multiple object, and date fields. Very often an admin will set up fields to hold text. Either long text fields to hold the full text of a document, or a field with numerous entries such as an email recipient field, or fixed length text fields to hold other email metadata fields, file names, and document ID numbers.

When using fixed length fields, keep in mind that they have certain limitations. No fixed length text field can hold more than 4,999 characters. If Unicode text is used in the field, the limit is 4,000 characters. Unicode text may be selected for the field so characters in non-Latin alphabets can be used. Unicode can be used for Arabic, Greek, Chinese, Japanese, Korean, Cryllic, Thai, and many other languages. [Only fixed-length text, long text, single choice, and multiple choice fields support Unicode.]

The default length for a fixed length text field is 255 characters, and Relativity recommends that this field be no more than 400 characters.

In addition you need to be sure that all of the fixed length text fields for any single object don't exceed more than 8,060 bytes (or 8KB) in total data size. Check the field usage for an object in order to confirm that this limit is not exceeded.

Searching for 32 character plus strings in dtSearch

Note that the dtSearch index in Relativity is configured so that it will cutoff any words which are longer than 32 characters. For example, this string:

aeccd639e83d0540ba407a252a23e53d1cfe71

. . .is 38 characters long. It appears in the EDRM Enron email data set.

But if you run a dtSearch search to find it in the searchable extracted text of a workspace, you'll get no results.

Modify the search by simply searching for the first 32 characters:

aeccd639e83d0540ba407a252a23e53d

. . . and the document in which it appears will come up in the search results:

It's not necessary to add an asterisk for a wildcard search after the 32nd character.
