Command Center Server uses the HTTPS Web protocol, but it is not a Web browser: it cannot be used to
●
access anything other than the HP Cloud, and it is not affected by Web browser vulnerabilities.
●
Communication between Command Center Client and Server is by HTTPS, and the port range is HTTPS
8443–8450 and HTTP 8080–8090.
●
Command Center MQTT broker and API Proxy port range are 1883–1891 and 8090–8099 respectively.
Encryption
●
The Command Center software transmits device data to HP Cloud servers using HTTPS. The identity of the
servers is verified, and the communication between the Command Center software and the HP Cloud
servers is encrypted using the Advanced Encryption Standard (AES) algorithm in Cipher Block Chaining
(CBC) mode, which ensures that the device data cannot be viewed or modified by any third party.
Device and software security
Full security audits and vulnerability scans are performed on the Command Center software before release.
●
Printers and supporting devices run on dedicated hardware and firmware that are not affected by typical
●
personal-computer vulnerabilities.
Full security audits and vulnerability scans are performed on all HP device firmware before release, and
●
firmware update files are digitally signed by HP and verified by the HP device before installation.
Data confidentiality
●
Device non-anonymous data are never shared with unauthorized third parties without the customer's
consent. The HP Cloud stores the device data in HP authorized data centers, which meet strict HP security
standards, and the system is periodically audited to help ensure the highest level of data security.
Proxy configuration
Command Center uses the system proxy configuration.
●
Networking requirements
Only outgoing HTTPS ports (typically TCP 443) need to be opened in the perimeter firewall; no incoming
●
network ports need to be opened.
The Command Center Server computer needs to allow incoming traffic to the Command Center Server
●
application so that Command Center Clients can connect to the server.
●
To give Command Center Server access to the HP Cloud, you should check that your network is not blocking
the following endpoints:
–
www.printos.com, port 443 (or https://www.printos.com)
3dpconf.heleni.me, port 443 (or https://3dpconf.heleni.me)
–
–
*.amazonaws.com, port 443 (or https traffic to any host on the domain amazonaws.com)
h19002.www1.hp.com, port 21 (or ftp://h19002.www1.hp.com)
–
Connection to the Internet must be DSL or better.
