There are many new technologies, controls, mechanisms, modules, libraries for protecting and securing assets and information. Usually these new technologies were created and developed by people with good skills in the field, however, one of the main problems is the implementation phase.
Believe it or not, most of the vulnerabilities, either published or zero-day, exist because of a bad or terrible implementation of something that is secure in escense.
Think about cryptography. In general, cryptographic standard algorithms are approved and validated by many cryptographers around the world but when it comes the implementation phase, the standard or algorithm is implemented by a group of peole working at the same company or sometimes by only one developer with limited training in security and/or cryptography.
One of these examples is WEP Security Protocol for Wireless communications. It has different vulnerabilities but particularly the vulnerability of the key stream is a consequence of a weakness in the implementation of the RC4 stream cipher, not the RC4 algorithm by itself.Continue reading Implementations: The Achilles heel in cybersecurity
