Security By Obfuscating Data Across Non-Adjacent Memory Locations, Aaron Vaage

Defensive Publications Series

The bytes that make up a data primitive (e.g., float, integer, etc.) are stored in adjacent bytes and in known order, based on a computer's architecture. Storing data in adjacent bytes is required by the hardware in order to operate on them. Compilers, in an effort to improve cache efficiency, pack primitives together. This packing indirectly communicates the relationship between primitives. When reverse engineering code, an attacker can observe the state of data on the stack. Knowing how the data is structured makes this much easier. The most reliable structuring is knowing how primitives will be structured. This disclosure describes …

System And Method For Detecting Infinite Signaling Loop In Hierarchical Nrf Deployments, Ravi Shekhar, Ameo Ghosh, Shantanu Bhate

Defensive Publications Series

For larger deployments, where multiple level of Network Function (NF) Repository Functions (NRFs) are deployed, the slightest misconfiguration could lead to an indefinite query loop between NRFs. The indefinite loop in the NRF query would mean repeated timeouts and/or failure of a service discovery request that a consumer had initiated to find a suitable producer. This could lead to signaling failure between a set of consumers and producers, which in turn can lead to Quality of Service (QoS) and Service Level Agreement (SLA) violations. A new Hypertext Transfer Protocol Version 2 (HTTP/2) header, Network Function (NF)-route-record, is proposed, which should …
