— Defending Indonesia's digital backbone and subscriber data
Telecommunications
Indonesia's telecommunications operators including Telkomsel, Indosat, XL Axiata, and Smartfren collectively serve over 370 million mobile connections, forming the backbone of the nation's digital economy. Telcos face unique cybersecurity challenges: protecting massive subscriber databases, securing 5G infrastructure rollouts, defending against SIM swap fraud, and complying with Kominfo's regulatory framework. Alpha Code provides specialized telecommunications cybersecurity covering network infrastructure, subscriber data protection, and regulatory compliance with PR 82/2022 and UU PDP requirements.

Understanding the risks
Key cybersecurity threats facing organizations in this sector.
01
SIM Swap Fraud & Subscriber Identity Attacks
SIM swap fraud enables attackers to hijack mobile numbers for OTP interception, banking fraud, and identity theft. Indonesian telcos face mounting pressure from regulators and banking partners to implement strong SIM swap prevention controls.
02
Network Infrastructure & SS7/Diameter Attacks
Legacy signaling protocols (SS7) and newer Diameter interfaces in 4G/5G networks expose telcos to location tracking, call interception, and subscriber data theft. These protocol-level attacks can compromise the entire subscriber base.
03
DDoS Attacks Targeting Network Availability
Telcos face massive DDoS attacks targeting DNS infrastructure, IP transit networks, and customer-facing portals. Volumetric attacks exceeding hundreds of Gbps can degrade service for millions of subscribers and enterprise customers.
04
5G & Edge Computing Security Risks
5G network rollouts across Indonesia introduce new attack surfaces through network slicing, multi-access edge computing, and virtualized network functions. Cloud-native 5G core architectures require fundamentally different security approaches than legacy network elements.
Stay compliant, stay protected
Key regulatory frameworks and standards your organization needs to meet.
PP 71/2019 & PR 82/2022
Government Regulation on Electronic System Operation
Requires telecom operators to implement information security management systems, conduct regular security audits, establish incident response capabilities, and register electronic systems with Kominfo. Includes data localization requirements for strategic electronic systems.
Kominfo Telecom Regulations
Ministry of Communication & IT Telecommunications Security Standards
Kominfo mandates telecom-specific security requirements including lawful interception capabilities, subscriber data protection standards, spam and fraud prevention measures, and network resilience requirements for critical telecommunications infrastructure.
UU 27/2022 (UU PDP)
Undang-Undang Pelindungan Data Pribadi
Telecommunications operators processing subscriber personal data must comply with UU PDP requirements including purpose limitation, data minimization, subscriber consent management, and 72-hour breach notification for incidents affecting customer data.

Common questions
How does Alpha Code address SIM swap fraud for telcos?
We implement multi-layered SIM swap prevention including real-time fraud scoring at point of sale, behavioral analytics for suspicious SIM change patterns, integration with banking sector fraud feeds, and enhanced identity verification workflows. Our approach has achieved over 90% reduction in successful SIM swap attacks for Indonesian operators.
What 5G security risks should Indonesian telcos prioritize?
Priority areas include securing the cloud-native 5G core against container and API attacks, implementing network slice isolation to prevent cross-tenant compromise, protecting multi-access edge computing nodes, and ensuring roaming security for 5G standalone networks. We recommend starting with a 5G security architecture assessment before commercial launch.
Can you help with Kominfo regulatory compliance for telcos?
Yes. We support compliance with all Kominfo telecommunications security requirements including ISMS implementation, security audit preparation, incident response capability development, and data localization assessment. Our team has experience with Kominfo audit processes and can prepare operators for regulatory reviews.
How do you protect subscriber data at telco scale?
We implement data protection programs covering subscriber databases, CDR repositories, billing systems, and CRM platforms. This includes data classification, encryption for data at rest and in transit, privileged access management for subscriber data systems, and continuous monitoring for unauthorized data access patterns.
What is the telco SOC different from a standard enterprise SOC?
A telecom SOC must process orders of magnitude more data, correlate events across network infrastructure and IT systems, detect telecom-specific threats like signaling attacks, and maintain visibility into both subscriber-facing and backend operations. We build purpose-fit telecom SOCs with specialized data pipelines, telco threat intelligence, and operator-grade scalability.
