The threat landscape for telecommunications is changing fast. Nation state actors and organised criminal groups are launching more deliberate attacks that compromise critical infrastructure. Malware, APTs, phishing, and insider threats are being combined with AI powered tools. Telcos need layered security. Zero trust is central. Real time monitoring, behavior analysis, and supply chain verification are essential. Collaborative efforts with government agencies and industry partners strengthen early warning. Investing in incident response lets providers stop damage before it spreads. These steps will help telcos defend against the cyber storm.
