Integrate this with your OS security plane, including as an input to your virus scanner, with a view ultimately to preventing control plane actions (like encrypting all your data) that emanate from untrusted or untrustworthy sources from ever being allowed write access outside of the mail spool.<br><br></div><div>The basic problem being, the OS treats a control plane action on a socket the same, regardless of you're logged in from iLo, or coming remote from Ukraine. Firewalls are essentially creating an artificial security plane, but it's a bandaid, and requires you architect your network to channel all your traffic through a chokepoint. If a socket's security profile was part of the API, the profile would follow control actions up the stack, and you'd get end to end security.<br></div><div><br></div><div>Kind regards<br><br></div><div>Paul Wilkins<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 17 May 2017 at 11:12, Mark Newton <span dir="ltr"><<a href="mailto:newton@atdot.dotat.org" target="_blank">newton@atdot.dotat.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On May 14, 2017, at 3:34 PM, Paul Wilkins <<a href="mailto:paulwilkins369@gmail.com">paulwilkins369@gmail.com</a>> wrote:<br>
