The new self-diagnosis report is intended to help in assessing the completeness and robustness of the current PTA threat model. For each of the model's entity types (Threats, Assets, Vulnerabilities and Countermeasures) it displays a table with a checklist of conditions which the entity should fulfill in order to be part of a 'well behaved' threat model. Thanks to Adi, <i>Pryn</i> for their creative ideas and their great help in the development of the ne report.

As of this built the <b>support for screen resolution of 800 * 600 was omitted </b>in order to enable better organization of threat model entities information in the data entry windows. PTA is best viewed in 1280 * 1024 screen resolution with large font size (120 DPI). Also supported 1280 * 1024 screen resolution with normal font size (96 DPI) and 1024 * 768 screen resolution with normal font size (96 DPI).</font></p> <p><font face="Verdana" size="1">In addition, build 1204 contains several usability improvements in the <b>Threat Builder</b> tool - thanks to <i>Laura Wood</i> from Meet Tech for her kind contribution on this issue. Many thanks to <i>Martin </i>for his remarks regarding inaccuracies in the <b>PTA Help</b> documentation (fixed :-) as well as to <i>Pryn</i> and <i>Boris</i> for their help in debug and testing of the <b>PTA Reports</b> system.</font></p> <p><font face="Verdana" size="1"><font face="Verdana">Read More: </font> <a href="http://www.ptatechnologies.com/latestupdate.htm"> http://www.ptatechnologies.com/latestupdate.htm</a></font></p> <p><font face="Verdana" size="1">Build 1203 contains an updated <b>code signing certificate</b> (issued by VeriSign, Inc) that replaces the older certificate which has been <b>expired</b> on 19 December 2007. Users who encountered difficulties in running PTA after this date are <b>urged</b> to download and install the latest cumulative update. </font></p> <p><font face="Verdana" size="1"><font face="Verdana">Read More: </font> <a href="http://www.ptatechnologies.com/latestupdate.htm"> http://www.ptatechnologies.com/latestupdate.htm</a></font></p> <p><font face="Verdana" size="1">As of build 1202, PTA can run on <b>Windows Vista Ultimate </b>32 and 64 bit versions. On the Vista 64 bit, PTA is automatically installed under the Program Files (x86) folder. </font></p> <p><font face="Verdana" size="1">The updated version contains usability enhancements which tend to improve the 'select from lists' GUI activities by restoring the latest selected entity position in each list. We hope it will increase productivity when building large threat models via the data entry screens. Thanks to <i>Serne Daniele</i> from the University of Wisconsin and to <i>David Benge</i> for raising the issue.   </font></p> <p><font face="Verdana" size="1">In addition, build 1202 contains important fixes for bugs such as crash of the <b>Status Screen</b> graph displays and the freeze of the <b>Optimized Risk Reduction Plan</b> report configuration screen under Vista - thanks to <i>Steve Lang</i> from NoHow for his published tip on these issues. </font></p> <p><font face="Verdana" size="1">Many thanks to <i>Jan Wellergard</i> from Teliasonera<i> and </i>and <i>K. Greenberg </i>from<i> </i>Terminal Desk for their efforts and dedication in debugging installation problems and for their contribution to the <a target="content" href="Support.htm">PTA Support </a>knowledge base.</font></p> <p><font face="Verdana" size="1"><font face="Verdana">Read More: </font> <a href="http://www.ptatechnologies.com/latestupdate.htm"> http://www.ptatechnologies.com/latestupdate.htm</a></font></p> <p><font face="Verdana" size="1">Build 1201 contains an important bug fix in the <b>Threat List </b>and<b> Threat Details </b>screens which caused, in some scenarios, loss of threat model information when not explicitly saved by user prior to exiting PTA - our thanks to <i>Steve Gilmore</i> from Frontier for his accurate report on this issue.   </font></p> <p><font face="Verdana" size="1">In addition, build 1201 contains numerous GUI fixes and usability enhancements. Many thanks to <i>Richi, Bruce, Francesco </i>and<i> Axel </i>as well as to hundreds of the PTA Free Program community members who keep sending us their important comments which help us constantly improve PTA. Special thanks to <i>Juan</i> and <i>Sahin</i> for their great help in following up with bug reports and testing.</font></p> <p><font face="Verdana" size="1"><font face="Verdana">Read More: </font> <a href="http://www.ptatechnologies.com/latestupdate.htm"> http://www.ptatechnologies.com/latestupdate.htm</a></font></p> <p><font face="Verdana" size="1">Build 1200 contains a major bug fix in the <b>Mitigation Plans by ROSI</b> report which caused the report to crash when the number of countermeasures in mitigation set exceeded 32 - thanks to <i>Paul Drennon</i> from the Virginia Department of General Services for his note on this issue and for his great help in debuging. The latest fix also corrects a rounding problem which caused inaccuracies in ROSI calculations on large threat models.   </font></p> <p><font face="Verdana" size="1">Build 1200 also provides substantial performance improvements which reduce the execution time of the <b>Optimized Risk Reduction Plan </b>report on large threat models - thanks to <i>Mark Weiger</i> and <i>NJ Raval</i> for their intensive help on this matter. </font></p> <p><font face="Verdana" size="1">In addition, build 1200 contains GUI fixes and usability enhancements which improve paging of large entity lists and navigating between the application's screens.
