inspection in lawful interception?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\" style=\"font-size:17px;line-height:1.7\">Deep packet inspection in lawful interception is the analysis of an ordered target&#8217;s intercepted traffic beyond addresses and ports. It decodes readable protocols and classifies encrypted traffic by application, fingerprint and activity type. It runs in the agency&#8217;s monitoring facility or at the operator&#8217;s point of interception, always within the scope of the interception order.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\" style=\"border-bottom-color:#dde6ec;border-bottom-width:1px;padding-top:18px;padding-right:4px;padding-bottom:18px;padding-left:4px;font-size:18px\"><summary><strong>Can DPI decrypt encrypted messenger traffic?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\" style=\"font-size:17px;line-height:1.7\">No. DPI does not break end-to-end encryption. It can show that a messenger was used, when, for how long and with how much data, and often whether the activity was a message or a call. Operators only remove encryption they applied themselves in their own network.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\" style=\"border-bottom-color:#dde6ec;border-bottom-width:1px;padding-top:18px;padding-right:4px;padding-bottom:18px;padding-left:4px;font-size:18px\"><summary><strong>Does provider-side DPI replace the full copy?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\" style=\"font-size:17px;line-height:1.7\">No. In Germany and many other jurisdictions, the operator must deliver a complete, unaltered copy of the target&#8217;s communication, unless the order explicitly limits the scope. DPI results are only delivered in addition. Agencies can therefore verify enriched data against the original traffic at any time.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\" style=\"border-bottom-color:#dde6ec;border-bottom-width:1px;padding-top:18px;padding-right:4px;padding-bottom:18px;padding-left:4px;font-size:18px\"><summary><strong>Is DPI for lawful interception compatible with net neutrality rules?<\/strong><\/summary>\n<p class=\"wp-block-paragraph\" style=\"font-size:17px;line-height:1.7\">Yes, if it is set up correctly. Regulation (EU) 2015\/2120 restricts DPI for traffic management but allows measures required to comply with Union or national law.
