The Application Security Ponzi Scheme

Discussing a different approach to application security where, rather than layering tools on top of applications, we focus on improving the tools developers use to built them.

Web application attacks also made up 13 percent of the total attacks observed by the HP TippingPoint IPS. This is an increase from 2010, during which the HP TippingPoint IPS measured Web application Attacks Seen from IDS/IPS attacks making up 10 percent of overall attacks. The next section will go into more detail about the Web application attacks seen in 2011.

The red “best fit” via least squares regression to the set of plotted blue points, one blue point for each quarter. T he red line is slightly smaller than that for the previous volume of this report and the p-value4 has increase o .543. Both of these results are consistent as indicators that the trend is flat—no increase or decrease i ication quality, as measured by the Veracode Security Quality Score, in our dataset since 4Q2009. 2009-4 2010-1 2010-2 2010-3 2010-4 2011-1 2011-2 2011-3 QUARTER 80 79 78 77 76 75 74 MEAN VERACODE SECURITY QUALITY SCORE Veracode Security Quality Score Trend by Quarter pvalue = 0.543: Statistically, the trend is flat.
