Offensive AI: The Arsenal of Attackers
On the other hand, attackers increasingly use AI to enhance their malicious campaigns:
- Deepfakes and social engineering: Creating extremely realistic fake images, videos and audios to manipulate victims.
- Attack automation: AI-based tools that enable unprecedented scale attacks.
- Evasion of defenses: Malicious systems that adapt to circumvent traditional security measures.
- Personalised Phishing: Highly convincing fraudulent messages based on victim-specific data.
" The automation provided by AI allowed hackers to develop more persuasive scams, combining SMS, WhatsApp and digital advertising to deceive victims and obtain financial data. "
AI cybersecurity for data protection
Effective data protection has become a strategic imperative, especially with increased threats and privacy regulations. The AI offers new approaches to addressing these challenges.
Implementing the Zero Trust Model with AI
The Zero Trust model operates with the principle of "never trust, always verify", and its integration with AI significantly increases its effectiveness:
- Identification of sensitive data and assets: Understanding needs where valuable assets are, including databases, servers or proprietary AI models.
- Mapping transaction flows: Analysis of how data moves on the network, helping to understand how AI systems interact with other elements.
- Smart Microsegmentation: Creation of safe zones in the network, using AI-powered analysis to establish normal behaviors and highlight anomalies.
- Advanced encryption: Protection of sensitive data at rest and in transit, with safe key management methods.
"As threats become more sophisticated and elaborate, companies must be proactive in protecting their IoT networks. By 2025, the integration of AI-driven security solutions and the adoption of Zero Trust architectures will be a key part of maintaining resilient and secure IoT networks. "
AI Governance and Regulatory Compliance
AI governance has become essential to ensure:
