Re: MQTT is IT not IoT
Yes it is IT security that fails here with MQTT implimentation.

 

It comes under configuration management.

Security needs to be abstracted away from business requirements.

Its a given in IoT.

 

Example used here already people 2016

 

https://www.wolfssl.com/wolfmqtt-v0-3-and-mqtt-secure-firmware-update-example/

https://www.wolfssl.com/docs/atmel/

 

My own IoT design's are designed to show the IT world how to do SECURITY.

In hardware. Like U2F from FIDO/FIDO2 for humans.

 

508a/608a or SAML11 for your edge nodes.

SAML11 for youre secure IoT hub talking MQTT over HTTPS.

 

It does not matter if your IP security fails.

The data is protected by hardware security.

Your heart beat system will tell you of DOS on your IP part.

 

ONLY PUBLIC KEYS are in the wild in secure IoT systems.

Re: MQTT is IT not IoT
Doesn't that go back to security policies? Disabling/securing services/ports?

MQTT is IT not IoT
The Internet of things (IoT) is the network of physical devices, sensors, actuators, and secure network connectivity which enable these objects to collect and exchange data

People need to know who to blame for poor design & security with IT systems.

 

IoT is a subset of IT, linked in a Venne diagram by the overlap, this is the place for the secure hub.

IoT securely designed does not rely on MQTT security.

IT security configuration has always been an issue.

If you cannot configure MQTT don't even think about adding on a IoT sub system.

The Year in Security: 2019
This Tech Digest provides a wrap up and overview of the year's top cybersecurity news stories. It was a year of new twists on old threats, with fears of another WannaCry-type worm and of a possible botnet army of Wi-Fi routers. But 2019 also underscored the risk of firmware and trusted security tools harboring dangerous holes that cybercriminals and nation-state hackers could readily abuse. Read more.

CVE-2019-12420
PUBLISHED: 2019-12-12
In Apache SpamAssassin before 3.4.3, a message can be crafted in a way to use excessive resources. Upgrading to SA 3.4.3 as soon as possible is the recommended fix but details will not be shared publicly.
CVE-2019-16774
PUBLISHED: 2019-12-12
In phpfastcache before 5.1.3, there is a possible object injection vulnerability in cookie driver.
CVE-2018-11805
PUBLISHED: 2019-12-12
In Apache SpamAssassin before 3.4.3, nefarious CF files can be configured to run system commands without any output or errors. With this, exploits can be injected in a number of scenarios. In addition to upgrading to SA 3.4.3, we recommend that users should only use update channels or 3rd party .cf ...
CVE-2019-5061
PUBLISHED: 2019-12-12
An exploitable denial-of-service vulnerability exists in the hostapd 2.6, where an attacker could trigger AP to send IAPP location updates for stations, before the required authentication process has completed. This could lead to different denial of service scenarios, either by causing CAM table att...
CVE-2019-5062
PUBLISHED: 2019-12-12
An exploitable denial-of-service vulnerability exists in the 802.11w security state handling for hostapd 2.6 connected clients with valid 802.11w sessions. By simulating an incomplete new association, an attacker can trigger a deauthentication against stations using 802.11w, resulting in a denial of...
