Who is securing 4glte

RTU capabilities have advanced significantly in support of intelligent operations, intelligent field, CCTV, mobile radios with cameras, field data connectivity, and other applications. Such applications require broadband connectivity, and the 4G LTE has the potential to satisfy all the aforementioned applications figure 1.

The ISA, Wireless Systems for Automation Committee grouped wireless applications into three classifications: monitoring, control, and safety figure 2. Wireless technology is becoming very popular for instrumentation ISA To understand the security architecture of the LTE, you need to know the LTE components and how these components communicate with each other and outside the LTE network. From a high-level network architecture point of view, LTE consists of the following three main components:.

UE stores user and device confidential information. This is called user-to-network registration, and it has to be secured. It is important to notice that data traffic carried over LTE is not encrypted end to end, which makes it subject to being captured by a nontrusted entity at certain points. Encryption starts at the end-user device and terminates at the network side, whereas in 3G, data encryption starts at the end-user device, crossing the network all the way to the radio network controller.

In this case, customer private information might not be protected. In the early deployment of LTE, it was possible to send the mobile subscription identification number, which contained some private user information, to the network in clear text if no IPSec solution was in place between the access layer and core layer. A Huawei e-LTE broadband multimedia digital wireless system was the communication platform serving different applications.

LTE reliability can connect many sites to minimize cost and increase flexibility. The POC clearly demonstrated that mutual authentication and encryption mechanisms protect IACSs, showing that 4G LTE technology with effective security controls can serve voice, video, and broadband industrial data and applications. Mohammed A. Al-Saeed is a network and systems specialist at Saudi Aramco in the process and control systems department, plants network unit. To protect profit dollars from being spent on recovery and remediation from security breaches, MNOs should keep abreast of prevalent security risks in both LTE and IP, the evolving security threatscape and actively invest in preventative security measures.

The paper does not present a comprehensive review of all possible security threats and does not address detection or recovery measures. The paper assumes that the reader has basic knowledge of LTE architecture, operations and common security threats and attacks. Broadband capable, LTE is designed to support up to Mbps peak downlink and peak uplink of 75Mbps.

LTE specifications include an all IP network including support for IPv6, flat architecture with fewer network elements, spectral efficiency, low latency as well as backward compatibility with existing wireless technologies. LTE operators benefit from improved cost efficiencies, both capex and opex, while dramatically increasing service performance for the subscriber. Below, we overview 4G LTE networks and the key role they play in smart home ecosystems. Since launching in the U.

It was not until that 4G "Fourth Generation" was introduced as a means for downloading more data at faster speeds, as well as enabling hotspots. By running smart devices on a 4G LTE cellular network, homeowners can improve equipment speed and functionality, as it transfers data at a quicker speed than other networks i. With a 4G LTE connection, homeowners can have faster networks, increased broadband capacity and greater connectivity.

Why does this matter? NPR estimates over 60 million Americans own at least one smart speaker, with many owning an average of 2. So, really, the safest way to ensure your security while on the go is to use a multi-layered approach. The use of anti-malware protection, firewalls, VPNs, and online common sense are also vital.
