R&S®Web Application Firewall – two editions to meet different needs

Since the release of 6.5.2, R&S®Web Application Firewall is available in two different versions or ‘Editions’: Business and Enterprise to address different use cases with the right capabilities.

Business Edition is the entry-level solution, run on less powerful appliances/virtual machines with limited core security functionalities (Generic patterns-ICX, Heuristics via Scoring List and API Security based on JSON / XML).

Enterprise Edition is essentially ‘Business Edition’ with extra features that advanced and enterprise users are likely to want to take advantage of: complementary security engines, available with Advanced Security, Extended APISecurity to protect API-based custom applications & Machine-to-Machine communications. Comprehensive Analytics & Reporting as well as Web Access Manager optional modules are only available withEnterprise Edition. IP Reputation is an optional service available with both Editions.

It is not possible to deploy different editions in the same environment. For more information about, see the Licenses page.

3 Behavior changes

3.1 Monitoring frequency

The monitoring frequency has been decreased to every 1 minute instead of every 15 seconds.

3.2 OpenSSL version migration

We’ve decided to not build our own OpenSSL and use the one from the CentOS system. It allows use to have the same SSL behavior for each component (Apache, Curl, Backend Monitor, etc …). This leads to deprecate some
ciphers and elliptic curves.

3.2.1 SRP SSL ciphers removed

Secure Remote Password ciphers are not handled by the WAF anymore. ‘SRP-*’ ciphers have been marked has “not supported” in SSL cipher profiles. They have to be removed from the ‘Selected Ciphers’ list before applying

Here is the list of unsupported ciphers since the 6.5.2 version:


For more information about ciphers see the SSL Cipher Profiles3 page.

3.2.2 SSL Elliptic Curve

The Elliptic Curves list that we handle as changed, we now supported the following curves:

  • secp256k1 : SECG curve over a 256 bit prime field
  • secp384r1 : NIST/SECG curve over a 384 bit prime field
  • secp521r1 : NIST/SECG curve over a 521 bit prime field
  • prime256v1: X9.62/SECG curve over a 256 bit prime field
