What kind of technologies and innovations have Taiwan Mobile implemented to enhance its services?
As part of Taiwan Mobile's transformative strategy, we've adopted the "Telco+Tech" approach. It has led to many innovations and enhancements in our services.
One of our significant innovations is the development of the "Gift-as-a-Service" model. It allows us to leverage our inherent telecom capabilities, extensive user base, and data security infrastructure to create diverse, new services. This model is designed to aid our enterprise clients in their digital transformation journey. We do this by offering services that enrich their operations.
A standout service under this model is the "Number Masking Service (安心call) " feature. It's designed to bolster privacy during customer interactions. This solution hides the customer’s real number by generating a temporary number printed on the delivery label. One that only the courier can call. Once the package is safely delivered, the number no longer works.
This solution protects the customer, courier, and e-commerce platform. In a competitive space such as e-commerce, peace of mind for customers and trust in the e-commerce company and delivery teams are paramount. This unique service has curbed related fraud incidents by over 90% within three years.
The "Anti-phishing Service (反詐戰警) " is another innovative service under Taiwan Mobile's Gift-as-a-Service (GaaS) model. Leveraging our telecommunications security technologies and vast data resources, we provide 24/7 monitoring for potential phishing websites. Upon detection of a fraudulent site that imitates one of our enterprise customers, we promptly alert the affected party.
We provide them with relevant information to aid their immediate actions such as reporting to the authorities. This service minimizes the damage inflicted by phishing websites on our enterprise customers and their brand reputation.
In the digital entertainment sector, we've made strides by securing rights to popular esports games like League of Legends. This move has led to a significant surge in our user base and revenue. Our new media services, such as MyMusic, MyVideo, and MyBook, have achieved significant market shares in Taiwan, further enhancing our digital entertainment services. Other innovative technologies like MyMoji and M+ meet (video conference) also hold great potential.
Through these innovations and our commitment to technological advancements, Taiwan Mobile is consistently improving its services while positioning itself at the forefront of the telecommunications industry.
How did the recent global events affect your field of work and Taiwan Mobile's technology and cybersecurity strategy? Were there any adjustments you had to make?
The COVID-19 pandemic compelled Taiwan Mobile to reassess our traditional work arrangements. The decision we made was to adopt a hybrid working model. We have decided to continue with a long-term hybrid working model. We allow each employee to choose to work from home for ten days each month.
This significant shift required our IT team to swiftly adapt and upgrade our existing infrastructure. We expanded our Virtual Desktop Infrastructure (VDI) and Virtual Private Network (VPN) capacity, implemented Multi-Factor Authentication (MFA) across the board, and bolstered our network security with increased vulnerability detection capabilities.
Our approach was holistic, centering on robust cybersecurity measures, clearly defined management structures, and effective, secure communication tools. Given the responsibility of protecting the data of our 7.5 million users along with our considerable internal business secrets, it was paramount for us to establish comprehensive, multi-layered data security measures.
Three critical strategies defined our approach to data security:
Micro-segmentation of core sensitive data. We introduced a segmented structure to our data storage, likened to the separate compartments in a submarine. By isolating sets of data, we increased the overall security against potential breaches.
Strengthened data management with VPN dual-factor authentication. To enhance our data access security, we made it mandatory for employees to use dual-factor authentication for VPN access. For highly sensitive data, we put additional measures in place, instantly blocking any suspicious activities.
Unified hardware use. To prevent unauthorized access, we mandated the use of company-issued laptops. Each one gets encrypted to prevent data leakage even in case of physical loss of the devices.
In addition to these technical measures, we focused on nurturing a security-conscious culture among our employees. We conducted rigorous training to ensure they understand their responsibility in maintaining company secrets. Also, to follow safe data handling protocols, even while working remotely. This involved steps like avoiding surveillance cameras, not connecting to public printers, and using only secure Wi-Fi networks.
We've also instituted precautionary measures such as embedding watermarks in critical documents to deter screen captures and data leaks. Moreover, to identify the source of any potential leaks, we use hidden watermarks that can be decoded to trace back to the specific employee account and the time of data leakage.
To facilitate seamless communication among staff, we employ our enterprise-grade instant messaging platform, M+. It has proven to be a reliable tool for regular team meetings, group discussions, and general communication.
Following this comprehensive approach, we've been able to successfully transition almost all our employees to a remote work setup. Today, except for roles requiring a physical presence, such as data center maintenance, inventory management, and in-store service, nearly all our teams can work effectively from anywhere.
What would you consider the main security threats surrounding mobile phones?
Mobile phones, being central to our digital lives, are susceptible to a range of security threats.
Some mobile operating systems, due to their open-source nature and fragmented ecosystem, often have backdoors or security vulnerabilities. There are countless brands and branches under the open-source ecosystem. That makes it difficult to maintain consistent security updates and standards across all devices. Such gaps get exploited by cybercriminals to gain unauthorized access to devices.
The mobile app landscape is vast and always evolving. Regulatory oversight often falls behind. This can lead to apps with inadequate security measures. Cybercriminals can exploit these vulnerabilities to steal data or execute malicious codes.
With the advent of mobile banking and online payment platforms, mobile phishing attacks have become more common. These involve deceptive messages, usually through SMS or email, that tricks users into revealing their sensitive information.
Cybercriminals often set up rogue Wi-Fi networks to trick users into connecting their mobile devices. Once connected, they can track the user's activities and steal sensitive data.
Mobile phones are often targeted with spyware and malware. Such software can record keystrokes, capture screen information, access contact lists, and track location. This all poses severe privacy and security risks.
Additionally, unlike desktop computers, mobile phones are portable. That means it's easier to lose or get stolen. In such cases, unless protected by robust security measures like encryption, biometric locks, or remote wipe capabilities, the data stored on the device can get accessed by unauthorized individuals.
To mitigate these threats, it's crucial to choose a trustworthy mobile phone maker. Regularly update the device's operating system and apps. Only download apps from trusted sources. Be wary of unsolicited messages. Connect to secure and trusted networks, and maintain robust physical security measures for the device.
In your opinion, what is the most significant cyberthreat that organizations face today? What are the top three best practices for cybersecurity that you would recommend to other organizations based on your experience at Taiwan Mobile?
In my opinion, the most significant cyberthreat that organizations face today is social engineering attacks. Humans are often the weakest and least predictable link in the entire security system. In recent years, there have been cases where criminal elements have exploited social engineering techniques to infiltrate systems and cause significant damage. That includes supply chain breaches in national defense departments and ATM networks in the financial industry.
Based on my experience at Taiwan Mobile, I would recommend the following top three best practices for cybersecurity to other organizations. First, every organization must conduct regular social engineering drills. Or conduct phishing tests targeting all employees. These drills should get conducted at least once per quarter for each employee. With a minimum hit rate of 1%, meaning that at least 1% of the participants should fall for the simulated attack. This helps strengthen the overall awareness and resilience of every employee.
Second, I recommend organizations conduct annual red team assessments. A red team, based on the latest attack techniques, should simulate real-world attacks to test the organization's defense capabilities. This exercise helps identify any vulnerabilities. It ensures that the organization's defense system remains robust.
Third, maintaining a strong cybersecurity culture is essential. This includes promoting regular security awareness training for employees. Also, implementing multi-factor authentication along with zero-trust infrastructure. And regularly updating and patching software and systems. It's important to establish incident response plans, which include conducting regular drills to ensure readiness in the event of a cyber incident.
By implementing these best practices, organizations can enhance their cybersecurity posture, mitigate the risks associated with social engineering attacks, and better protect their valuable assets and sensitive information.
What role do you see emerging technologies such as AI and machine learning playing in the future of cybersecurity for Taiwan Mobile?
We have already incorporated AI into our cybersecurity services for enterprise clients at Taiwan Mobile. For example, our " Anti-phishing service (反詐戰警)" constantly monitors global websites using AI to compare similarities in layouts, images, and text. This helps identify and block or take down counterfeit websites for our corporate clients.
Additionally, we have started using advanced AI techniques to detect fraudulent text messages and prevent them from reaching our customers. We believe that AI has significant potential in various aspects of information security, including event recognition in SOC monitoring centers, detection of abnormal user behavior in application systems, and identification and mitigation of malicious traffic in data networks.
As emerging technologies continue to evolve, AI and machine learning will play an increasingly vital role in the future of cybersecurity at Taiwan Mobile. These technologies can analyze vast amounts of data in real time, detect patterns, and identify anomalies that may indicate potential security threats. By leveraging AI and machine learning, we can enhance our threat detection capabilities, respond to incidents more quickly, and strengthen our overall cybersecurity defenses.
Furthermore, AI can help us stay one step ahead of cybercriminals by enabling proactive threat intelligence and predictive analytics. By analyzing historical data and continuously learning from new threats, AI-powered systems can anticipate and prevent emerging cyber threats before they cause significant damage. This proactive approach allows us to minimize the impact of potential security breaches and protect our customers' sensitive information effectively.
We see AI and machine learning as essential tools for the future of cybersecurity at Taiwan Mobile. By harnessing the power of these technologies, we can enhance our threat detection, response, and prevention capabilities. Ultimately, we're providing our customers with more robust and effective cybersecurity solutions.
