 I understand that we have several types of sec_modes. 
 However, regarding modes with MITM - I don&amp;#39;t understand how exactly those modes protect from MITM. What does it do? 
 
 Thanks!</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 07 Jun 2021 09:36:29 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/75385/ble---mitm-protection" /><item><title>RE: BLE - MITM protection</title><link>https://devzone.nordicsemi.com/thread/313862?ContentTypeID=1</link><pubDate>Mon, 07 Jun 2021 09:36:29 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:5903d79c-e008-44c2-a696-3b71fc226b9a</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;Please read litterature you may find on Bluetooth core specification.

This have very short range, so any attacker would need to be very close.&lt;/p&gt;

&lt;p&gt;What about BLE connection with a PC, via NFC?&lt;/p&gt;
&lt;p&gt;What is the meaning of MITM configuration in this case?&lt;/p&gt;
&lt;p&gt;Thanks!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: BLE - MITM protection</title><link>https://devzone.nordicsemi.com/thread/310711?ContentTypeID=1</link><pubDate>Thu, 20 May 2021 11:15:45 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:ee64f479-f73b-46de-a9a8-b79fe9a87ea6</guid><dc:creator>Roei</dc:creator><description>&lt;p&gt;Thanks!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: BLE - MITM protection</title><link>https://devzone.nordicsemi.com/thread/310709?ContentTypeID=1</link><pubDate>Thu, 20 May 2021 11:12:34 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:7ec55727-bd09-49df-ab64-f9265fa8d262</guid><dc:creator>Kenneth</dc:creator><description>&lt;p&gt;MITM require the user to actively input a passkey that is displayed on the peer device. Thereby it is not possible for a man in the middle (MITM) attack. You can refer to the bluetooth core spec for more information about the various security modes and levels.&lt;/p&gt;
