SECURITYGEN IDENTIFIES THE CYBERSECURITY PRIORITIES FOR MOBILE OPERATORS IN 2023

Open architecture, non-standalone roaming, nation-state attacks, ransomware, and
the need for more industry collaboration are among the major 5G security
challenges that operators must address in the year ahead.
January 19, 2023

ROME, Jan. 19, 2023 /PRNewswire/ -- SecurityGen, the award-winning global
provider of security solutions and services for the telecoms industry, today
announced its cybersecurity priorities for telecom operators in 2023.



"As 5G's global footprint increases, the number of cyber threats targeting 5G
increases as well," said SecurityGen co-founder and CTO Dmitry Kurbatov. "In
2023, operators must be aware of the range of these threats and take necessary
steps to properly defend their networks, protect their customers, and safeguard
their operations and revenue."

Kurbatov identifies the main factors shaping the risks and threats that
operators must prepare for in the year ahead as follows:

      1.  5G related challenges


 * 5G is open for integration - but also open to attack

Unlike previous mobile network generations like 3G and LTE, 5G is designed from
the ground up to be flexible and open for integration with multiple external
systems. However, the same open architecture that enables this flexibility and
easy integration can also make 5G vulnerable and exposed to threats and hidden
vulnerabilities.

The challenge for operators is to maximise 5G's advanced functionality and
interoperability while also recognizing this vulnerability and minimizing the
threats arising from 5G's extra openness compared to previous network
generations.

 * Beware of roaming traffic from non-standalone 5G

As operators deploy more 5G networks and more users purchase 5G smartphones, the
volume of roaming traffic between 5G networks increases. But the majority of
this extra roaming traffic goes through non-standalone 5G networks which still
use unsecure legacy technology for their core networks, including signaling
protocols such as GTP and Diameter, which have proven to be hackable in recent
years.



Without proper security measures in place, 5G is vulnerable to threats
originating from non-5G networks carried in non-5G network traffic – but which
are able to damage and disrupt 5G services.

      2.  Cyberattacks from hostile states and organized crime

Telecom networks are critical national infrastructure, which makes them
high-value targets for cyberattacks, especially during times of conflict and
heightened geopolitical tensions. The growing use of mobile - especially 5G -
for connecting and remote monitoring of everything from energy grids and
automated factories to smart cities and transport systems, amplifies the damage
and disruption that an attack on an operator's network could inflict. Mobile's
importance also makes it a target for organized crime groups to launch
financially motivated attacks of their own aimed at operators or their
subscribers.

      3.  Operators as high-value targets for ransomware



The number and frequency of cyber-attacks such as ransomware and phishing show
no signs of slowing down. The threat of ransomware is already well known:
however in 2023, expect the bad actors behind them to become more advanced
and more selective in their attacks - including targeting mobile networks as the
means to breach telecom operators and access the valuable customer data they
hold.

      4.  New industry regulations on security but operators must do more
themselves 

National and pan-regional regulators are pushing the telecom industry to comply
with new security requirements that address the heightened threat of cyberattack
on digital infrastructure and telecom networks as part of it.

Mobile network security is still perceived as an after-thought. Rather than
adopt a network-wide, security-by-design approach, many operators continue to
rely on inefficient one-off security techniques which leave parts of their
networks exposed to hackers.

      5.  Effective cybersecurity also depends on collaboration

 * Hinders knowledge sharing

When companies and experts share their knowledge and experience, everyone
benefits. But with international cooperation undermined by current geopolitical
rivalries and tensions, divisions might open between operators and other telecom
industry players, industry regulators and national governments that make it more
difficult to cooperate on collective joint efforts for better cybersecurity.

 * Cyber-security skill shortages

Cyber-security continues to suffer an ongoing shortage of skilled workers,
especially in areas that require specific expertise such as telecoms. Combined
with the lack of knowledge sharing, the skills shortage makes it harder to
encourage and develop new talent. The telecoms industry, led by operators, needs
to step up and invest in training initiatives to attract new workers and provide
them with the requisite skills needed to grow the cyber-security talent pool.

Against this range of threats, Dmitry identifies the following steps for
operators to strengthen the security and resilience of their 5G networks:

 * Make the security of your 5G network as much of a commercial and operational
   priority as its performance in terms of speed, throughput, and coverage. The
   current economic conditions should not put operators off investing in proper
   security measures. Security is more efficient and cost-effective when it is
   built-in across the entire system, and not just a patch on the surface.
 * Adopt a defence-in-depth approach based on continual network-wide assessments
   and monitoring. 5G networks are a step-change in complexity that are more
   like IT systems than legacy mobile networks. Regular security checks,
   continuous analysis and other established cybersecurity methods fine-tuned
   for the telecom environment will provide the level of detail and in-depth
   scrutiny that's needed to ensure a 5G network is secure against advanced
   attacks.
 * Effective 5G security requires more than just installed software solutions
   and automated monitoring and testing. Extensive and ongoing training is also
   essential, so that operator security teams can explore and stay up to date
   with the latest cyberthreats - and also identify new vulnerabilities as they
   emerge.

"Operator security teams must be mindful of the new, unique security challenges
specific to 5G while at the same time not losing sight of the threats inherited
by legacy technologies within 5G's set up," explained Kurbatov.

"Telecom security cannot be solved by a single-point solution, it requires a
comprehensive strategic approach along with collaboration between ecosystem
players. Operators and their industry partners should cooperate closely with
governments and regulators to ensure cybersecurity receives the attention and
investment to protect users and ensure that networks remain safe, secure and
resilient," he concluded.
