Hosi Avaliasaun ICT no Governasaun ba Cybersecurity, Jestaun Servisu no Transformasaun Dijitál
Iha organizasaun sira iha tempu ohin, Information and Communication Technology (ICT) la’ós de’it funsaun suporte ne’ebé responsabiliza ba komputadór, rede no rezolve problema tékniku.
Divizaun ICT ne’ebé di’ak no estruturadu tenke bele apoia operasaun organizasaun, proteje informasaun, aumenta produtividade, ajuda tomada desizaun, jere risku teknolojia no kria baze forte ba transformasaun dijitál.
Ba organizasaun ne’ebé foin hahú estabelese Divizaun ICT ka hakarak hametin funsaun ICT ne’ebé eziste ona dezafiu boot la’ós de’it atu hili teknolojia saida mak atu sosa.
Dezafiu boot liu mak atu hari’i kombinasaun ne’ebé loos entre ema, governasaun, prosesu, seguransa, infraestrutura, sistema no servisu.
Artigu ida-ne’e aprezenta abordagem prátika ida atu estabelese Divizaun ICT hosi baze, ho fó atensaun liu ba loron 90 dahuluk.
1. Hahú Hosi Organizasaun, La’ós Hosi Teknolojia
Erro komún ida bainhira estabelese funsaun ICT mak hahú diretamente hosi teknolojia.
Pergunta dahuluk sira la presiza:
Servidór saida mak ita tenke sosa?
Software saida mak ita tenke instala?
Komputadór hira mak ita presiza?
Pergunta importante liu mak:
