I-Three Major Attacks Enyanga Amabili - I-Time To Put Our Engineers Hats On Umbhali weTupou VI "Ko e Otua mo Tonga ko hotau tofi'a" - God and Tonga are our inheritance Ukubuyekezwa kwe-Reality We Needed Kuyinto ngokuvamile ukuqala, thina lokugqibela ukuhamba kulungile. Yes, kule usuku futhi isikhathi, Information Security (Infosec) kuyinto isebenzo esivamile. Ngaphezu kwalokho, sibe manje Imininingwane online. I-Government's Digital Transformation and Cybersecurity Frameworks Nangona kunjalo, izivakashi ezintathu eziphambili ezivamile eminyakeni angu-2+ zihlanganisa ukuthi amandla lethu okwengeziwe kuyinto ingxubevange lethu okungenani eli-human aspect. TCC (Tonga Communications Corporation) - 2023 - Medusa ransomware MOH (Ministry of Health) - 2025 - I-INC Ransom I-attack I-TPL (i-Tonga Power Limited) - I-2025 Ngemuva kwalokho, sinamathela i-policy yethu, kodwa singazi ukuthi ukuxhumana ne-policy discussions kuncike kuphela izinzuzo zobuchwepheshe. Ngakho-ke, thina siphinde i-Engineers zethu "ON" futhi zihlole ngaphezulu ukuze ufunde izinzuzo zethu njengama-root causes of problems yethu. The Harsh Truth - Policy ≠ Ukuvikelwa Nangona i-Tonga iye yenza imiphumela emangalisayo ekubunjweni kwezinkqubo ze-cyber security kanye nezinkqubo ze-digital transformation, inkinga okuphazamiseka kuyinto ukuthi i-paper shields akuyona i-digital bullets. Three major cyber attacks in just over two years is not bad luck, it is a systemic failure of our cybersecurity infrastructure where both technical and human aspects are critical components. I-Attack Timeline - I-Pattern Emerges March 2023 - Tonga Communications Corporation (TCC) Umthombo we-Medusa Ransomware Ukusabela: Izinsizakalo zokusabela, ukunakekelwa kwamakhasimende I-Root Cause: I-Stat owned telecommunications infrastructure vulnerability June 2025 - Ministry of Health (MOH) Umbhali: INC Ransom Group Imiphumela: I-National Health Information System yakhelwe ngokuphelele Iindleko: I-US$1 Million I-Ransom Request (i-Unpaid) Umphumela: Izixhobo ze-manual e-hospitals ezine 2025 - Tonga Power Limited (TPL) Imininingwane: Imininingwane ezidlulileyo ezijoliswe Ukucaciswa: Ukucaciswa kwama-infrastructure ebalulekile I-Technical Vulnerabilities - I-Real Engineering Problem Thina siphinde ukucubungula isimo nge-policy rhetoric kanye nokufunda iziphumo zofuzo zofuzo zofuzo zofuzo: I-Exposure ye-Infrastructure Legacy : Inani le-infrastructure ebalulekile e-Tonga ibhekwa kakhulu emakhemikhali abalandeli nabantu abalandeli abalandeli.
