Cybersecurity and Digital Infrastructure Insights
While Verizon attributed the cause as a software failure, the occurrence of such an incident at this magnitude shows how vulnerable critical infrastructure is to being taken offline within seconds, either by cyberattack or technology failure.
Such outages highlight the necessity of:
- Real-time monitoring of systems to catch malfunctions early.
- Periodic stress testing and software audits to prevent failures.
- Open and timely incident response policies for customer trust.
With digital communications increasingly dependent on telecom networks, operators are under siege by cyber attacks at all times. Even a programming bug can cause a chain reaction, affecting emergency services, businesses, and regular users.
