attacks. It can be configured by going to System Settings > Privacy & Security (<span class="NoBreak">macOS 13</span> or later), the Security & Privacy pane of System Preferences (<span class="NoBreak">macOS 12</span> or earlier), or by using a configuration profile with the Firewall payload installed manually or provided by an MDM solution. The following configurations are supported:</p><ul><li><p>Block all incoming connections, regardless of app.</p></li><li><p>Automatically allow built-in software to receive incoming connections.</p></li><li><p>Automatically allow downloaded and signed software to receive incoming connections.</p></li><li><p>Add or deny access based on user-specified apps.</p></li><li><p>Prevent the Mac from responding to ICMP (Internet Control Message Protocol) probing and portscan requests.</p></li></ul><Footer>Published Date: February 18, 2021</Footer><div class="LinkUniversal"><strong>See also</strong><a href="https://support.apple.com/en-gu/guide/security/secure-access-to-wireless-networks-sec8a67fa93d/1/web/1" class="xRef AppleTopic">Secure access to wireless networks</a><a href="https://support.apple.com/en-gu/guide/security/wi-fi-password-sharing-security-iphone-ipad-secd2015ef35/1/web/1" class="xRef AppleTopic">Wi-Fi password sharing security on iPhone and iPad</a></div><div class="LinkDownload single"><p><a href="https://help.apple.com/pdf/security/en_US/apple-platform-security-guide.pdf" id="sec1d75ee4db" class="URL">Download this guide as a PDF</a></p></div></body></div> </div> </div> </div> <div id='aside-hidden-content'> <div class="main"> </div> </div> <div id='helpful-rating-wrapper'> <div id='helpful' class='ratings okapi-enabled'> <div id='question-state' class='show'> <fieldset> <legend> <span id="okapi-a">Helpful?</span> </legend> <div class='helpful-btn-grp'> <button class='button button-secondary' id='yes-button' data-ss-analytics-link-component_name='helpful' data-ss-analytics-link-component_type='helpful' data-ss-analytics-link-text='yes' data-ss-analytics-event=acs.link_click title='Solved my problem'> Yes </button> <button class='button button-secondary' id='no-button' data-ss-analytics-link-component_name='helpful' data-ss-analytics-link-component_type='helpful' data-ss-analytics-link-text='no' data-ss-analytics-event=acs.link_click title='Not helpful'> No </button> </div> </fieldset> </div> <div id='feedback-state' class="form-element form-textbox-labelbelow hide"> <form autocomplete="off"> <input type='hidden' id='form-counter-error-message' value="Maximum character limit is 250." /> <label id='feedback-label' data-no-label="Thanks for letting us know." data-yes-label="We’re glad this article helped." ></label> <div class='form-element form-textbox-labelbelow' id='feedback'> <div class="textarea-wrapper"> <span class='form-label' id='optional_label' aria-hidden='true'></span> <div> <textarea class='form-textbox form-textbox-textarea form-counter-textarea form-textbox-entered' data-no-placeholder="How can we make this article more helpful?
