Safeguarding your keys in a TPM

TPMs (Trusted Platform Modules) are beneficial for storing private keys due to their hardware-based security features, which offer robust protection against various forms of cyber attacks. Additionally, TPMs provide a secure environment isolated from the main operating system, enhancing the confidentiality and integrity of stored private keys. This post explains how to use the OpenSSL TPM Provider with Security Plugins.

Hardening Secure Data Distribution Service (DDS) Deployments: Enforcing Security Policies at the Network Layer

In today's technological landscape, addressing security concerns and implementing robust policies in distributed applications is crucial. To address those concerns, RTI provides Connext DDS Secure. It provides robust authentication, encryption, and access control mechanisms for Data Distribution Service (DDS) systems. With fine-grained control of the publication and subscription of topic data, data encryption, and data filtering, and integration with external security infrastructure, Connext DDS Secure restricts network access to authenticated and authorized participants, protecting the integrity and confidentiality of the data and data flows. It complies with security standards, offers performance optimization, and facilitates secure data caching and persistence.
