Integrated Security for Telco Cloud Edge and Private 5G

/in


Integrated-Security

Telcos and enterprises are realizing the need to move toward the edge and deploy edge cloud solutions to leverage the massive advances in transmission offered by 5G. Benefits such as speed, low-latency, capacity will drive major transformation for telcos and enterprises opening new revenue opportunities and business models.

Telcos and enterprises are exploring new use cases by deploying edge clouds and bringing content and applications closer to the users and billions of IoT devices to meet the low-latency requirements. The Ericsson 2022 mobility report forecasts that over 30 billion Internet of Things (IoT) connected devices will be connected by 2027.

The 5G core network functions could be deployed as a microservice in a private data center of the CSP and enterprise network or a public cloud, the shift to the edge and deploying telco cloud edge services and enterprise hybrid private 5G networks introduce new security threats that are associated with the 5G and edge deployment.

Even though there are security risks with 3G/4G, these risks are mainly associated with external attacks. However, with 5G/MEC/IoT architecture, this risk becomes larger and more serious. 5G core and edge sites can be attacked from the internal network in an “inside-to-outside” approach. Considering that 5G provides high-speed internet broadband, connecting a massive number of consumer and IoT devices, it can be considered as a new point of attack for the 5G cloud edge architecture.

Such massive transformation is forcing telcos and enterprises deploying cloud edge and private 5G services to re-think their security and network protection. There are many challenges in how telcos and enterprises deploy security solutions today as they cannot provide integrated 5G core and security solutions to adapt with cloud-edge use cases. For example, moving to the edge will require a low footprint, automation, scaling and simplified lifecycle management (LCM). Given the increase in the number of edge sites that may be deployed, it will be very complex to manually manage and scale different security solutions. The typical deployments of…

A staggering 5,25,820 counts of malware infections have been identified amongst the users of the four telecom operators in the country, according to the Horizon Scanning Report for Bangladesh Telecom Operators prepared by the cyber threat intelligence researchers of Bangladesh e-Government CIRT (Computer Incident Response Team). These counts of malware infections have been accounted for during the first quarter of this year, i.e. from January 2022 to April 2022.

All four telecom operators in Bangladesh have a significant infection rate of numerous malware for network communications. The total malware infections amongst the users have been accounted for during the first quarter of this year, i.e. from January 2022 to April 2022 in the Horizon Scanning Report for Bangladesh Telecom Operators.

Grameenphone, having the highest subscriber base with 83.02 million users, leads the way with 294,657 total malware counts and 47 unique counts of malware infections. The virus called ‘android.hummer’ has the highest infection rate of 24.4%.

Coming in second place is Robi Axiata, with 104,578 total malware counts, having 40 unique counts of malware infections. The ‘avalanche-andromeda’ virus has a 12.85% infection rate and leads the malware chart for the second-largest telecom operator in the country.

Meanwhile, Banglalink, having the third-highest subscriber base with 37.41 million users, has a total malware count of 98,423 with 31 unique cases of software infections. The infection rate is highest for the ‘android.hummer’ virus, as it has an infection rate of 21.64%.

Teletalk, the government-based telecom operator, has a total malware count of 28,162 with 31 unique malware infections. The ‘avalanche-andromeda’ virus has the highest count having an infection rate of 11.39%.

Unsurprisingly, all the operators have the highest number of infections in Dhaka, the capital city of Bangladesh.

According to a globally accessible knowledge base of hacking techniques based on real-world observations, developing and refining the necessary analytics is vital as it can aid in detecting evidence which can confirm the presence of…
