While tried, tested and trusted, many of these protocols are dated. They were often applied without an authority model but depended on implicit trust within a closed industry. Now look at the inherent insecurity of this approach in the context of the role in operating several network functions, and it will be clear that any security threats identified against these services will have a high impact. Many will remember that in 2017 an incident in Washington DC, close to the White House, saw attackers use a fake base station and SS7 access to obtain subscriber information.
Predominantly these attacks target consumers and cause a breach of privacy with all the ramifications of potential regulatory action and reputational damage.
The network perimeter is blurring, and the cloud is being regularly leveraged to facilitate operators’ operations. The cloud is where network, storage, and compute resources often reside these days. And yes, an external supplier manages all these applications.
The loss of direct control of such critical operations may diminish the operator’s level of control over the network performance, optimization, data, and quality of services. The operator also loses the capability to assess and alleviate security threats directly. They are forced to depend solely on contractual or service level agreements with the cloud provider. Seen in that light, cloud services pose a potential combination of risks concerning network availability, supply chain, and privacy.
This year has seen a major IoT thrust. And obviously, security threats are emerging. The industry has identified that several customer device manufacturers have little consideration for, or competency in, security. It’s not uncommon for them to hand over the accountability to secure the device to the uneducated customer without security instructions. These devices, when deployed, are also attached to the operator’s network. Attacking the network by leveraging these devices could potentially harm operators.
