What security is in place on My Signage Portal?

Cloud Server:

The CMS is hosted on an Amazon Web Services (AWS) server https://aws.amazon.com, using an SSL encryption method and an ISO 27001 Security Certification. Nexpose & OpenVAS Vulnerability scan takes place monthly, as well as the operating system (OS) for the server being updated and patched monthly by AWS.

The cloud uses ‘AWS: EBS Provisioned IOPS storage (SSD)’, which securely protects all saved data and keeps a continuous backup on the server. This is secure storage system and the second largest data centre in Amazon’s global infrastructure. The server runs Red Hat Enterprise Linux 7, which is consistently kept up-to-date with the most recent and highest version of the OS. Red Hat Enterprise Linux 7 is used instead of Microsoft Windows because of the much smaller quantity of vulnerability issues and known viruses on the Linux system. The Linux OS is also more reliable and secure when preventing malicious software making it much better at handling important data on a large system. The server also features a Cloud Watch system, which monitors the status of the server in real-time and sends updates to the engineers every minute. We have in place a scalable computing power system, allowing us to expand the server to suit our requirements if higher demands of data transfer are needed.

The network administrators for the content management system (CMS) are fully trained engineers, and have a minimum of 4 years’ experience in our operations. Our very own development team also help maintain the server and processes. There is a locked IP that allows only our engineers to maintain and manage the server through a secure port.. This is connected to using an SSH server with the terminal emulator PuTTY. Our development team also help maintain the server and have a great understanding of the processes involved.

Security:

The cloud data has to go through Amazon’s Key Management Service (KMS) https://aws.amazon.com/kms/ before any data has been transferred to the screen/player. The KMS is a managed server that enables us to easily create and control the keys used for cryptographic operations. The service provides a highly available key generation, storage, management and auditing solution for us to encrypt data within the CMS. Events that breach security are logged and analysed by the KMS in real-time. Amazon’s KMS monitors all the system resources and protects the confidentiality and integrity of data. KMS uses FIPS 140-2 validated Hardware Security Modules (HSM).

Amazon’s EC2 Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) offers key features to help protect EC2 instances. Any breaches are logged and analysed by the IDS system. These monitor the inbound and outbound data, as well as the system resources. Any attempted intrusions will also be logged by the IPS. There are also engineers on standby 24/7 to respond to any vulnerability alerts. All security events are logged and reported. Any suspicious attempts are also reported immediately by AWS. The engineers and developers also have IT server maintenance training and server training, which is provided quarterly.

There are multiple security hardening procedures in place, such as trimming and restricting remote services on the AWS Server and minimisation of services the server is running. The CMS is also the only thing that the server hosts so there are no other processes being run on the server. It also features an encrypted security key, and uses secured packages when sending and receiving information. Each screen/player that is connected to the CMS will have a security identifier, which is unique for each screen/player. There is a watchdog system in place on the screen/player itself that will react to unwanted data or activity and begin restoring configurations from the server once abnormalities are detected. Finally, two separate firewalls are in place in front of all data going in and out of the server.

To keep accounts secure on My Signage Portal a CAPTCHA authentication system is in place to protect spam and password decryption. When logging into an account there is a simple test that requires the user to type out the exact numbers shown into a field that differentiates between human and computer access.

Ports and Protocols:

The server connects to the screen/player using the HTTP+HTTPS web protocols. HTTP is standard, but HTTPS is there for users that require it. If the HTTPS option is used, this will encrypt the data both in and out with real-time generated security keys, preventing any information being intercepted by others. On this same protocol, the server will transfer files via a packet system, and require the screen/player to return a message to the server every time it receives a part of the packet, allowing the next part to be sent.

Port 80 (or 8001) using the HTTP protocol is used to download media from the server as well as configuration files. Port 4700 on the UDP protocol is used to send remote commands to the screen/player from the server. Port 4701 on the TCP protocol is used to let the screen/player log into the server, and also register heartbeats for monitoring purposes. Finally, ports 16732 and 16733 on the UDP protocol are used for local synchronisation of the content of multiple screens/players.
