These techniques help adversaries observe the environment and determine next steps for target selection and Lateral Movement. They also allow adversaries to explore what they can control and gain insight on interactions between various control system processes. Discovery techniques are often an act of progression into the environment which enable the adversary to orient themselves before deciding how to act. Adversaries may use Discovery techniques that result in Collection, to help determine how available resources benefit their current objective. A combination of native device communications and functions, and custom tools are often used toward this post-compromise information-gathering objective.</p> </div> </div> <div class="col-md-4"> <div class="card"> <div class="card-body"> <div class="card-data"><span class="h5 card-title">ID:</span> TA0102</div> <div class="card-data"><span class="h5 card-title">Created:&nbsp;</span>17 October 2018</div> <div class="card-data"><span class="h5 card-title">Last Modified:&nbsp;</span>09 March 2023</div> </div> </div> <div class="text-center pt-2 version-button permalink"> <div class="live"> <a data-toggle="tooltip" data-placement="bottom" title="Permalink to this version of TA0102" href="/versions/v16/tactics/TA0102/" data-test-ignore="true">Version Permalink</a> </div> <div class="permalink"> <a data-toggle="tooltip" data-placement="bottom" title="Go to the live version of TA0102" href="/tactics/TA0102/" data-test-ignore="true">Live Version</a><!--do not change this line without also changing versions.py--> </div> </div> </div> </div> <h2 class="pt-3" id ="techniques">Techniques</h2><h6 class="table-object-count">Techniques: 5</h6> <table class="table-techniques"> <thead> <tr> <td colspan="2">ID</td> <td>Name</td> <td>Description</td> </tr> </thead> <tbody> <tr class="technique"> <td colspan="2"> <a href="/versions/v16/techniques/T0840"> T0840 </a> </td> <td> <a href="/versions/v16/techniques/T0840"> Network Connection Enumeration </a> </td> <td> Adversaries may perform network connection enumeration to discover information about device communication patterns.

RF communication frequencies vary between 3 kHz to 300 GHz, although are commonly between 300 MHz to 6 GHz. The wavelength and frequency of the signal affect how the signal propagates through open air, obstacles (e.g. walls and trees) and the type of radio required to capture them. These characteristics are often standardized in the protocol and hardware and may have an effect on how the signal is captured. Some examples of wireless protocols that may be found in cyber-physical environments are: WirelessHART, Zigbee, WIA-FA, and 700 MHz Public Safety Spectrum. </td> </tr> </tbody> </table> </div> </div> </div> </div> </div> </div> <!--stop-indexing-for-search--> <!-- search overlay for entire page -- not displayed inline --> <div class="overlay search" id="search-overlay" style="display: none;"> <div class="overlay-inner"> <!-- text input for searching --> <div class="search-header"> <div class="search-input"> <input type="text" id="search-input" placeholder="search"> </div> <div class="search-icons"> <div class="search-parsing-icon spinner-border" style="display: none" id="search-parsing-icon"></div> <div class="close-search-icon" id="close-search-icon">&times;</div> </div> </div> <!-- results and controls for loading more results --> <div id="search-body" class="search-body"> <div class="results" id="search-results"> <!-- content will be appended here on search --> </div> <div id="load-more-results" class="load-more-results"> <button class="btn btn-default" id="load-more-results-button">load more results</button> </div> </div> </div> </div> </div> <div class="row flex-grow-0 flex-shrink-1"> <!-- footer elements --> <footer class="col footer"> <div class="container-fluid"> <div class="row row-footer"> <div class="col-2 col-sm-2 col-md-2"> <div class="footer-center-responsive my-auto"> <a href="https://www.mitre.org" target="_blank" rel="noopener" aria-label="MITRE"> <img src="/versions/v16/theme/images/mitrelogowhiteontrans.gif" class="mitre-logo-wtrans"> </a> </div> </div> <div class="col-2 col-sm-2 footer-responsive-break"></div> <div class="footer-link-group"> <div class="row row-footer"> <div class="px-3 col-footer"> <u class="footer-link"><a href="/versions/v16/resources/engage-with-attack/contact" class="footer-link">Contact Us</a></u> </div> <div class="px-3 col-footer"> <u class="footer-link"><a href="/versions/v16/resources/legal-and-branding/terms-of-use" class="footer-link">Terms of Use</a></u> </div> <div class="px-3 col-footer"> <u class="footer-link"><a href="/versions/v16/resources/legal-and-branding/privacy" class="footer-link">Privacy Policy</a></u> </div> <div class="px-3"> <u class="footer-link"><a href="/versions/v16/resources/changelog.html" class="footer-link" data-toggle="tooltip" data-placement="top" data-html="true" title="ATT&amp;CK content v16.1&#013;Website v4.2.1">Website Changelog</a></u> </div> </div> <div class="row"> <small class="px-3"> &copy;&nbsp;2015&nbsp;-&nbsp;2024, The MITRE Corporation.
