Abstract(s)
O "Grupo Altice Portugal", daqui em diante apenas referida como Altice Portugal, possui um grande
número de entidades interligadas (MEO, MEO Empresas, Altice Labs, ...) que tornam a coordenação
global da cibersegurança uma tarefa difícil para o Chief Information Security Officer (CISO), pois ele
deve monitorizar continuamente a ciber-higiene de cada uma, assim como as suas interdependências.
Este projeto tem como objetivo dar continuidade ao trabalho realizado pela Altice Portugal e
desenvolver um sistema de monitorização diária da ciber-higiene e do risco de ransomware da Altice
Portugal e de cada uma de suas entidades constituintes. De modo a chegar a este objetivo, são recolhidos
e analisados dados de várias fontes, abrangendo diversos aspetos da segurança e ciber-higiene e são
realizados Dashboards constituído por várias worksheets, cada uma delas com o intuito de fornecer
diferentes níveis de informações valiosas ao CISO para permitir uma melhor análise e conseguir
melhorar a prevenção ativa da empresa.
Este relatório fornecerá uma visão geral do trabalho realizado, as tecnologias usadas para atingir o
objetivo, algumas funcionalidades que poderão vir a ser desenvolvidas futuramente por forma a tornar
esta solução ainda mais útil para a empresa e para o CISO. Também vai mostrar os resultados alcançados
onde se confirma a eficácia do sistema desenvolvido, demonstrando que o sistema cumpre o seu papel
de análise da ciber-higiene da Altice ao longo do tempo a partir das métricas escolhidas.
The "Altice Portugal Group", from now on referred to as Altice, has many interconnected entities (MEO, MEO Empresas, Altice Labs, ...) that make global cybersecurity coordination a difficult task for the CISO (Chief Information Security Officer), as he must continually monitor the cyber hygiene of each one, as well as their interdependencies. This project aims to continue the work carried out by Altice Portugal and develop a system for daily monitoring of cyber hygiene and the ransomware risk of Altice Portugal and each of its constituent entities. To achieve this objective, data is collected and analyzed from various sources, covering different aspects of security and cyber-hygiene and a Dashboard made up of several worksheets is created, each of them with the aim of providing different levels of valuable information to the CISO to carry out a better analysis and have access to improving the company's active prevention. This report will provide an overview of the work carried out, the technologies used to achieve the objective and some features that may be developed in the future to make this solution even more useful for the company and the CISO. It will also show the results achieved which confirm the effectiveness of the developed system, demonstrating that the system fulfills its role of analyzing Altice's cyber hygiene over time based on the chosen metrics.
