1 Identify and assess risks

The first step to ensure network security is to identify and assess the potential risks and vulnerabilities that the broadband provider faces. This involves conducting regular audits, tests, and scans of the network components, systems, and processes, as well as monitoring the external and internal threat landscape. By identifying and assessing the risks, the broadband provider can prioritize and address the most critical and urgent issues, and plan for contingencies and recovery.

L'identification et l'évaluation des risques passent tout d'abord par l'analyse en profondeur des menaces qui pèsent sur les systèmes informatiques, que ce soit des menaces physiques ou logicielles. Par exemple en faisant des audits à travers des tests de pénétration, ceci dans le but de mettre en lumière (évaluer et identifier) des potentielles failles présentes sur le système informatique

Implementar firewalls de rede robustos para proteger os perímetros da rede contra acessos n?o autorizados e ataques de hackers. Isso inclui a configura??o de regras de firewall para filtrar e bloquear tráfego malicioso antes que ele alcance os sistemas internos da rede. Utilizar sistemas de detec??o e preven??o de intrus?es para monitorar e analisar o tráfego de rede em busca de atividades suspeitas ou padr?es de comportamento maliciosos. Isso ajuda a identificar e bloquear ataques em tempo real, antes que possam causar danos à rede. Implementar filtros de conteúdo para bloquear o acesso a sites maliciosos, phishing e conteúdo nocivo.

Utilizar criptografia de dados para proteger a confidencialidade e integridade das informa??es transmitidas pela rede. Isso inclui o uso de protocolos de criptografia como SSL/TLS para proteger comunica??es web e VPNs (Virtual Private Networks) para criar túneis seguros de comunica??o entre dispositivos remotos.

1. Implement Robust Firewall Solutions: Deploy firewalls at network perimeters to filter and monitor incoming and outgoing traffic, blocking unauthorized access and potential cyber threats. 2. Regular Security Audits and Updates: Conduct routine security audits to identify vulnerabilities and apply timely updates and patches to network equipment and software to address security flaws. 3. User Education and Awareness: Provide comprehensive training to users on cybersecurity best practices, such as creating strong passwords, recognizing phishing attempts, and avoiding suspicious websites, to mitigate the risk of cyber attacks.

2 Implement security policies and standards

The second step to ensure network security is to implement security policies and standards that define the roles, responsibilities, and rules for the broadband provider and its employees, partners, and customers. These policies and standards should cover aspects such as access control, encryption, authentication, authorization, data protection, incident response, and compliance. The broadband provider should also train and educate its staff and stakeholders on the security policies and standards, and enforce them with regular reviews and audits.

os provedores de conectividade (ISP – Internet Service Provider) podem ajudar a reduzir os ataques DDoS implementando boas práticas que impe?am que as infraestruturas deles e de seus clientes sejam abusadas para gerar ataques. Para isso, é essencial o combate aos ataques do tipo DRDoS. Os principais motivos dos ataques DRDoS serem t?o potentes s?o o tráfego de endere?os forjados (spoofados), o abuso de servi?os que permitem a amplifica??o de tráfego e a grande quantidade de equipamentos de redes, como CPEs.

3 Apply security technologies and tools

The third step to ensure network security is to apply security technologies and tools that can help detect, prevent, and mitigate cyber attacks. These technologies and tools include firewalls, antivirus, anti-malware, VPNs, IDS, IPS, DDoS protection, SIEM, and AI. The broadband provider should also update and patch its software and hardware regularly, and use secure protocols and configurations for its network devices and connections.

habilitar filtro antispoofing, implementando mecanismos de egress filtering que impedem a saída da rede de pacotes com endere?o de origem pertencente a uma rede reservada e que n?o fa?a parte de um dos blocos de endere?os da rede interna. Detalhes sobre esse tipo de filtragem podem ser encontrados no Portal de boas práticas para a Internet no Brasil.

4 Manage security incidents and events

The fourth step to ensure network security is to manage security incidents and events that may occur despite the preventive and protective measures. This involves having a clear and effective incident response plan that outlines the roles, procedures, and resources for handling and resolving security incidents and events. The broadband provider should also have a backup and recovery plan that can restore the network functionality and data in case of a breach or damage. Moreover, the broadband provider should analyze and learn from the security incidents and events, and improve its security posture accordingly.

Tentar identificar o tipo de ataque: após concluir que realmente se trata de um ataque DDoS é necessário tentar entender as suas características e identificar qual o seu tipo, ou seja, se é volumétrico, de aplica??o, de exaust?o de recursos de hardware ou misto.

5 Collaborate and coordinate with others

The fifth step to ensure network security is to collaborate and coordinate with others who are involved or affected by the broadband network. This includes other broadband providers, regulators, law enforcement, customers, vendors, and industry associations. By collaborating and coordinating with others, the broadband provider can share information, best practices, and resources, as well as align its security policies and standards with the industry norms and regulations. Furthermore, the broadband provider can leverage the collective intelligence and expertise of others to enhance its security capabilities and resilience.

Colaborar y coordinarse con otros afectados durante un ciberataque ofrece ventajas clave. Permite intercambiar información, aprender de las experiencias de los demás, coordinar respuestas efectivas, aumentar la resiliencia ante futuros ataques, mejorar la visibilidad de la amenaza y contribuir a la seguridad cibernética en general. Esta colaboración fortalece la capacidad de respuesta, la seguridad y la resiliencia de las organizaciones frente a las amenazas cibernéticas.

6 Adapt and innovate continuously

The sixth step to ensure network security is to adapt and innovate continuously to cope with the changing and evolving cyber threats and challenges. This means that the broadband provider should constantly monitor and evaluate its network performance, security level, and customer satisfaction, and identify areas for improvement and innovation. The broadband provider should also adopt new and emerging technologies and methods that can improve its network efficiency, reliability, and security, and stay ahead of the competition and the cyber adversaries.

I think a very good approach is the accountability through logs and live monitoring, detecting behaviors and patterns, turns the task into proactive instead reactive, and in my personal opinion that is always a better approach.

Los proveedores de banda ancha pueden adaptarse e innovar continuamente utilizando inteligencia artificial (IA) para garantizar la seguridad de la red frente a ciberataques. Pueden emplear IA para la detección avanzada de amenazas, análisis de anomalías, automatización de respuestas, mejora de la seguridad de los endpoints, adaptación continua y análisis predictivo de amenazas. Esto les permite detectar y mitigar rápidamente amenazas, adaptarse a los cambios en el panorama y ofrecer una protección más robusta contra los ciberataques.
