The experience in combat conditions gained in Ukraine’s cyberwar against Russia and in Israel’s war against Hamas gives me valuable knowledge and skills.
Not only the media and VIPs are helpless against virtual weapons, computer viruses, and a wide variety of spyware, but also any arsenal of weapons: nuclear missiles, airplanes, artillery, and tanks. The most advanced models of military equipment can be destroyed, for example, by false commands introduced by hackers into electronic control systems or chips responsible for controlling formidable weapons. The United States, Israel, and Western Europe have long been trying to find a solution to these threats, and have established cyber threat prevention centers.
My analytical mind, knowledge of the cyber weapons arsenal and global expertise in modern technologies help me build effective strategies in cyber warfare. Just like the best field generals, I understand modern cyber threats and attack methods. I understand the tools and techniques used by attackers and how best to counter them. I develop plans and strategies to protect information systems and data from cyber threats, as well as build effective methods of responding to cyber attacks and coordinate the actions of cyber fighters to minimize damage and neutralize attacks.
