Technical Challenges in Data Security

Many Irish healthcare providers, specilarly in thee public sector, operate on a patchwork of legacy IT systems. These systems of ten lack modern desimplifies, have inconsistent patch management, and may nott support robutt accords controls.

Inquident Encryption and Data Transferr Security

While code (store in datases, backup, archives) and data in transit (moving between systems or across networks) require strong dicotiption standards such as AES- 256 for storage and TLS 1.3 for communications. However, many healtcare organizations still rely on older procurs, uncreamind pted internal networks, or poorly configured virt private networks (VNs).
