www.mm-alumni.de

Letzte Woche ist nach mehreren Monaten Vorbereitung, Entwicklung und Beta-Test die neue Webseite des Manage&More Alumni Netzwerks gestartet: www.mm-alumni.de

Die Webseite enthält einen neben eines kleinen öffentlichen Teils zu repräsentativen Zwecken, einen großen internen Bereich, dessen Kern die "Erfahrungsdatenbank" bildet. Die Erfahrungsdatenbank ist eine speziell auf die Bedürfnisse der Mitglieder des Manage&More Alumni Netzwerks angepasste Wissensdatenbank (neudeutsch: Knowledge-Database). Hier können Erfahrungen mit beispielsweise Studien, Firmen, Gründungen oder Stipendien ausgetauscht werden. Über eine Weltkarte (Google Maps, mit gecachten, zuvor geokodierten Adressen) können sich Mitglieder leicht einen Überblick über die "Erfahrungsorte" des Netzwerks machen.

mm-alumni.de Interner Bereich

mm-alumni.de Interner Bereich

Weiterhin existiert für die Vorstände ein komplettes Backend-Interface, mit dem sich alle Objekte komfortabel bearbeiten lassen:

mm-alumni.de Backend für Vorstandschaft

mm-alumni.de Backend für Vorstandschaft

Das Projekt wurde von mir (Alex) im Rahmen meiner Tätigkeit als IT-Vorstand des Manage&More Alumni Netzwerks entwickelt. Als Grundlage dient Symfony 1.4 mit Doctrine als ORM. Weiterhin kamen folgende Module zur Verwendung: Open Flash Chart, PHPExcel, ZendGdata (zur Google Spreadsheet Anbindung), SwiftMailer, FeedWriter, sowie jQuery und jQuery UI.

Patrick entwarf und entwickelt das neue Logo und CI des Manage&More Alumni Netzwerks; auch das Webseitendesign stammt von ihm.

Integrating CKFinder into your symfony Application

When integrating CKEditor and CKFinder into your symfony application, you have to modify the ckfinder/config.php-file, to check if the user has the permissions to use the CKFinder als file-browser.

It's that easy (we asume, CKFinder is located in /web/js/ckfinder):

function CheckAuthentication()
{
require_once(dirname(__FILE__).'/../../../config/ProjectConfiguration.class.php');
$configuration = ProjectConfiguration::getApplicationConfiguration('yourApplicationName', 'prod', false);
$context = sfContext::createInstance($configuration);

if ($context->getUser()->functionToCheckPermission())
return true;
else
return false;
}

So finally you just have to implement a method in your myUser.class.php-file, that checks whether the user may or may not use CKFinder!

Attack Scenarios for possible Misuse of Peripheral Parts in the German Health Information Infrastructure

Recently the follow-up to my first paper was published. Hence, number three is again about the German Health Insurance Card's usage in physicians' practices.

Sunyaev, A.; Kaletsch, A.; Duennebeil, S.; Krcmar, H. (2010): Attack Scenarios for possible Misuse of Peripheral Parts in the German Health Information Infrastructure. In: Proceedings of the 12th International Conference on Enterprise Information Systems (ICEIS 2010). Funchal, Madeira - Portugal, 8 - 12 June, 2010. Volume DISI, pp. 229-235.

Abstract:

This paper focuses on functional issues within the peripheral parts of the German health information infrastructure, which compromise security and patient’s information safety or might violate law. Our findings demonstrate that a misuse of existing functionality is possible. With examples and detailed use cases we show that the health infrastructure can be used for more than just ordinary electronic health care services. In order to investigate this evidence from the laboratory, we tested all attack scenarios in a typical German physician’s practice. Furthermore, security measures are provided to overcome the identified threats and questions regarding these issues are discussed.

Comparative Evaluation of Google Health API vs. Microsoft Healthvault API

Based on research, which I did last year in spring, my second paper was recently published.

Sunyaev, A.; Kaletsch, A.; Krcmar, H. (2010): Comparative Evaluation of Google Health API vs. Microsoft Healthvault API. In: Proceedings of the Third International Conference on Health Informatics (HealthInf 2010), January 20-23, 2010, Valencia, Spain, pp. 195-201.

Abstract:

Electronic Health Records (EHR) offer patients the opportunity to access their own medical records. Google and Microsoft recently extended their public services by introducing internet-based personal healthcare information platforms – Google Health and Microsoft HealthVault. Over one hundred thousand people have registered at the two services since they were launched. Both companies invite other for-profit companies as well as non-profit organizations to participate in the design, development, and distribution of their own healthcare-related applications. Such applications are based on the free accessible EHR systems of Google and Microsoft and provide further benefits to patients. Due to its simplicity and usability, an API design could determine the variety of value-added applications developed and thus be essential for the commercial success (and potential market dominance) of one of these EHR systems. This work examines and compares the designs of Google Health API and Microsoft HealthVault API. Such an evaluation provides benefits for both research and practice: on the one hand, the results provide an overview of the different open API designs, and, on the other hand, the results provide the developer community with useful lessons learned from comparing the examined APIs.

(Ab-)using Smarty cache in order to load Websources into own Webpage

This article discribes an easy way to cache data received from other websites in order to improve the performance of one own's site. The method was successfully tested on alexander-kaletsch.de (blog) and birgit-kaletsch.de (kurse-detail).

Theory: Download Websource only after cache got invalid.

First you have to create a dummy template: _cache.tpl

{$cache}

The index.php:

require_once("Smarty/Smarty.class.php");

$smarty = new Smarty();

$smarty->compile_dir     = "_comp/";
$smarty->template_dir     = "tpl/";
$smarty->cache_dir        = "_cache/";
$smarty->cache_lifetime = 60*60; // 1h

$smarty->caching = 2;

if(!$smarty->is_cached("_cache.tpl", "blog")){
$smarty->assign("cache", file_get_contents("http://www.patworx.de/blog/index.php"));
}

echo $smarty->fetch("_cache.tpl", "blog");

if(!$smarty->is_cached("_cache.tpl", "ak")){
$smarty->assign("cache", file_get_contents("http://www.alexander-kaletsch.de/"));
}

echo $smarty->fetch("_cache.tpl", "ak");

Security Analysis of the German Electronic Health Card’s Peripheral Parts

Based on my Bachelor's Thesis research my first paper was published some weeks ago. Finally I found time to post it in here.

Sunyaev, A.; Kaletsch, A.; Mauro, C.; Krcmar, H. (2009): Security Analysis of the German electronic Health Card’s Peripheral Parts. In: ICEIS 2009 - Proceedings of the 11th International Conference on Enterprise Information Systems. Milan, Italy, 6-10 May 2009. Volume ISAS, pp. 19-26.

Abstract:

This paper describes a technical security analysis which is based on experiments done in a laboratory and verified in a physician’s practice. The health care telematics infrastructure in Germany stipulates every physician and every patient to automatically be given an electronic health smart card (for patients) and a corresponding health professional card (for health care providers). We analyzed these cards and the peripheral parts of the telematics infrastructure according to the ISO 27001 security standard. The introduced attack scenarios show that there are several security issues in the peripheral parts of the German health care telematics. Based on discovered vulnerabilities we provide corresponding security measures to overcome these open issues and derive conceivable consequences for the nation-wide introduction of electronic health card in Germany.
