This article examines the growing threat of DDoS extortion campaigns targeting Internet Service Providers (ISPs), drawing on real-world incidents investigated by Link Technologies, Inc. It explains how these attacks differ from ransomware, outlines three practical levels of DDoS defense, and provides actionable strategies that ISPs and network operators can implement to improve resilience against modern large-scale attacks.
This article explains how recent router compromises, highlighted by national security advisories, are typically the result of outdated software and misconfiguration rather than vendor-specific flaws. It outlines how proper firmware management, firewall design, and lifecycle awareness significantly reduce risk. It also emphasizes the role of proactive support, such as services from LinkTechs, in maintaining secure and reliable network infrastructure.
RouterOS Apps introduce a simplified way to deploy containerized services directly on MikroTik routers, allowing operators to run infrastructure tools such as DNS, monitoring, and logging without separate servers or virtualization platforms. With just a few clicks, RouterOS automatically deploys containers along with required networking and firewall configuration. This capability enables ISPs and network operators to host operational services closer to the network while reducing complexity and infrastructure overhead.
Dennis Burgess, CTO of Link Technologies, emphasizes that effective network monitoring is foundational to ISP reliability and customer experience. He recommends deploying at least three core systems—a high-level overview tool (like The Dude), a deep monitoring platform (such as Zabbix), and external internet monitoring—to ensure visibility, rapid troubleshooting, and proactive alerting. A fourth system, BGP monitoring, becomes critical for networks with multiple upstreams to detect routing issues that may not trigger session failures. Together, these layered monitoring approaches improve uptime, reduce support load, and ensure a resilient, well-managed network.
