Stepping up security

In late 2016, NCBI dropped support for HTTP requests and restricted their web resources to HTTPS. EBI went HTTPS by default in October 2017 and UniProt has announced that it will go HTTPS-only in June 2018. The UniProt change will cause a problem with Database Manager in older versions of Mascot. This article summarises the effects of turning off HTTP, [...]

Mascot Security: priority settings

An earlier article looked at privacy settings in Mascot security. This article looks at priority settings; the settings that allow one user group to run bigger or longer or more complex searches than another. Many aspects of searches can be limited by user group. The important ones are: SEARCH: Allow msms no enzyme searches SEARCH: Maximum number of concurrent searches [...]

Improved security for Mascot Installations under Linux

In the manual, we recommend (because it is easiest) that ms-monitor.exe is run as root. However, a more secure arrangement is to run ms-monitor.exe as a less privileged user. By default, Apache cgi processes run as www-data:www-data, and for most distros, this is set in the envvars file: export APACHE_RUN_USER=www-data export APACHE_RUN_GROUP=www-data This can however, be overriden in the /etc/apache2/apache2.conf [...]

Using Mascot security to share search results

How can you share Mascot result reports with external colleagues or customers? There is a help page that describes some off-line solutions, but it doesn’t cover the most flexible solution, which is to use Mascot security to provide external users with limited access to your Mascot Server. In a typical configuration, these users would be able to view their own [...]

Don’t get stuck in a queue

Mascot Server doesn’t queue searches. This isn’t because we can’t be bothered to write the code. Its because we don’t believe queuing would improve performance or usability. The times taken for individual searches cover a very wide range. A PMF or a small MS/MS search with few variable modifications and tryptic specificity might take seconds. A large MS/MS search of [...]
