In an industry that prides itself on keeping the world connected digitally, the telecom sector is no stranger to security threats. With the highest number of global DDoS attacks, it has long relied on firewalls as a primary threat aversion mechanism.
Legacy firewalls have been a mainstay for a while
By filtering out suspicious traffic or rogue elements from within their global network through predefined rules, firewalls have safeguarded the telecom sector from several threats. 5G rollout is underway on a big scale globally. As the world prepares for a new dimension of digital complexity, traditional firewalls may not do the job for telecom players anymore.
The challenges of legacy firewalls
They are incapable of supporting modern network complexities. They could also fall short of being able to handle newer operating nuances like cross-protocol integration, security node-based signaling in the place of core network nodes, etc.
However, an even bigger threat lies in the inability of legacy firewalls to counter new-age cyber threats.
The digital world which is growing exponentially is also now one of the major avenues of fraudulent activities and exploitation. From the theft of sensitive customer data to impersonation or identity fraud, the breadth of the threat landscape is immense.
Cybercriminals are even deploying artificial intelligence-driven agents into the digital space to break safeguards and penetrate deeper into enterprise networks. Very often, the entry point they choose to attack is the gateway used by an enterprise to connect with the internet. Suspicious links embedded in SMS text messages can go past legacy firewalls and easily put users at risk.
That’s why traditional firewalls deployed by telecom operators must be equipped with the intelligence or knowledge needed to combat such threat agents.
The shift to new generation firewalls – Why now?
The need to strategically move into the next generation of firewall capabilities is critical given the industry’s role as a key pillar of digital transformation in all sectors. Additionally, here are some of the top reasons why telecom operators must embrace the next generation of firewall technologies to stay competitive:
Rise of cloud
Today, cloud services are used by almost every business irrespective of its size or domain. With the cloud, user authentication becomes a major step of the usage journey. Most businesses rely on traditional methods like SMS-based OTP authentication or call-based authentication to help end-users avail cloud services. However, legacy firewall technologies cannot distinguish between genuine authentication prompts sent by the business and fraudulent signals ingested into the network by criminals.
New age threats
Telecom fraud is a major threat that needs attention. Studies point out that in 2023, telecom fraud has risen by as much as 12%. This translates to billions of dollars in lost revenue.
Similar to SMS frauds, and authentication fraud via missed calls mentioned before, there are a number of diverse network-focused threats in play today. Through fraudulent routing, fraudsters may bypass legacy firewall protection and reach end users with communication scripted as a genuine business message. Other means like bulk malicious SMS traffic may cause legacy firewalls to be jammed and entry into the network automatically provisioned to prevent further congestion. Such threats pose significant risks to telecom operators, compromising network security and yielding negative outcomes.
Growth of IoT
With 5G technology taking off at scale, businesses will look forward to mobilizing their resources around promising technologies like the Internet of Things (IoT). Worldwide spending on IoT is expected to surpass the USD 1 Trillion mark by 2026.
A lot of machine integrations will happen in services traditionally offered by businesses. For example, scenarios like a smart fridge placing replenishment orders to the nearest grocery retailer or an e-commerce service autonomously can become a normal thing soon. There is a catch here. With machine communication over the internet becoming mainstream, it is extremely important to authenticate credentials of control data. Control data could be transmitted in the form of messages, calls, etc. Traditional legacy firewalls are not capable of handling such advanced authentication processes.
The promise of new-generation firewalls
As telecom companies gear up to spearhead digital innovation, they can certainly leverage highly intelligent firewalls like the GTS Armour firewall to guard their progress at all times. Such new-generation firewalls come with a host of features that are much needed in the emerging security and evolving landscape of telecom usage.
One of the striking benefits that telecom companies can leverage from modern firewall solutions is the use of artificial intelligence and machine learning in firewall operations. From threat discovery to neutralization, AI-powered continuous analysis of network traffic by modern firewalls holds great promise. They equip telecom players with the much-needed confidence to partner with other businesses for their digital ambitions.
Platforms like the GTS Armour offer protection against high-end security threats like identity fraud. There is a combination of techniques that firewalls use. Some include robo-calling, interconnect fraud prevention guards, virtual machine fraud detection, etc. Such firewall solutions offer peace of mind for telecom players as they seek to expand their business partnership ecosystem. Through powerful contextual analysis such AI-powered firewall solutions can easily identify and block fraudulent or suspicious text messages way before they are delivered to end users.
Telecom companies are perceived as a foundational element of modern digital experiences. Securing their operations is of primal importance for telecom businesses. Investing in state-of-the-art firewall solutions like Armour helps telecom companies improve their trust credentials in the market with proven security.
