Security weakness : Forward Secrecy
0%
Description
Lavoisier server does not support Forward Secrecy with the reference browsers .
Forward secrecy (FS) also known as perfect forward secrecy (PFS), is a property of secure communication protocols in which compromises of long-term keys does not compromise past session keys. Forward secrecy protects past sessions against future compromises of private key. The very popular RSA key exchange doesn’t provide forward secrecy. You need to support and prefer ECDHE suites in order to enable forward secrecy with modern web browsers.

Ajout du support des ciphers suite activés par la property 'lavoisier.ssl.ciphers' dans lavoisier-service.properties:
lavoisier.ssl.ciphers=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_DHE_DSS_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_SHA256,TLS_ECDHE_RSA_WITH_AES_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_SHA,TLS_ECDHE_RSA_WITH_AES_256_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_SHA384,TLS_ECDHE_RSA_WITH_AES_256_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_SHA,TLS_DHE_RSA_WITH_AES_128_SHA256,TLS_DHE_RSA_WITH_AES_128_SHA,TLS_DHE_DSS_WITH_AES_128_SHA256,TLS_DHE_RSA_WITH_AES_256_SHA256,TLS_DHE_DSS_WITH_AES_256_SHA,TLS_DHE_RSA_WITH_AES_256_SHA
Par défaut, c'est la config du moteur SSL de Java qui est prise en compte.
