Dutch minister of safety and justice Klaas Kijkhoff has responded in writing to questions from Labour Party PvdA about recent disruptions at Ziggo, saying internet problems due to large-scale DDoS (distributed denial of service) attacks are unavoidable. The minister said that it was primarily the job of ISPs to secure their systems against such attacks, which hit cable operator Ziggo in August.
PvdA MP Astrid Osse Bridge had written earlier, saying she wanted to know to what extent public services are affected by DDoS attacks on major ISPs and what the government could do to prevent such events.
Dijkhoff wrote that the government has taken action to minimize effects of DDoS attacks on their own networks and systems, adding that it was up to the government to implement such measures for ISPs. The minister said companies and bodies involved must ensure that consequences are minimised. They could take prevention measures such as by addressing and sharing information about joint botnets, networks of hijacked computers used by hackers to stage cyberattacks.
Ziggo took two heavy DDoS attackes on 18 and 19 August.
