Web App Security with Cenzic and NetScaler Run periodic scans to keep website secure

Import into NetScaler Application Firewall

Web vulnerability scan results from Cenzic

© 2012 Citrix

How Does It Work?

•  Vulnerabilities are found during a Cenzic Hailstorm software or SaaS security scans

•  Development team logs into Cenzic Hailstorm and/or receives vulnerability report with details

•  Remediation process begins •  Export Cenzic Hailstorm vulnerability report to a

NetScaler Application Firewall •  The XML file of scan results is imported into NetScaler

Application Firewall •  The imported, Cenzic-generated rules are then bound

to the NetScaler Application Firewall profile

•  Quick protection against Cenzic Hailstorm identified application vulnerabilities. No additional configuration and learning is required

Certificate Lifecycle Management

•  Enable rapid migration from 1024 bit keys to 2048 across the IT infrastructure • Venafi has the certificate inventory • Venafi provide automated replacement of

keys • Venafi can enforce 2048 policies / compliance

•  Improve performance by offloading SSL certificates to NetScaler devices • Expand NetScaler platforms to enable 2048

compliance without degrading performance • Venafi integration with NetScaler enables

automated deployment of certs to NetScaler from other systems

•  Venafi discovers certificates in your network

•  Venafi validates inventory daily

•  Venafi monitors for & reports on inventory expirations, policy violations

•  Venafi acts as the intermediary to manage the enrollments, approvals and issuances of certificates

•  Venafi automatically issues, uploads and binds new certificates in the Citrix NetScaler

•  Venafi regularly rotates certificates, providing increased security agility

How Does it Work?

10. Associate certificate with virtual server

6. Submit CSR 7. Retrieve Cert

3. Approve Key Gen

•  Solution Components •  Citrix NetScaler - Version 9.2 or later •  Identity Provider such as Active Directory or equivalent

LDAP based system •  RSA Adaptive Authentication Server for secondary

authentication of users based on behavioral and other inputs

•  How does the integration work? •  User attempts to access a system protected by Adaptive

Authentication •  User's activity is analyzed by the RSA Risk Engine and is

assigned a Risk Score •  RSA Policy Manager determines Risk using behavioral

analysis

•  User is directed to "Step-Up Authentication"

Intrusion Detection and Intrusion Protection (IDS/IPS)

© 2012 Citrix

•  Two modes of deployment •  Off of span port •  Inline mode

•  Solution Components •  Citrix NetScaler front-ending web applications & sites •  Sourcefire 3D Sensor •  Sourcefire Defense Center

•  How does it work? •  Sourcefire 3D Sensor detects an attack •  Sourcefire Defense Center creates an ACL policy and

sends it to Citrix NetScaler through the NetScaler API •  Citrix NetScaler applies the policy and blocks the attack

How Does IDS/IPS Integration Work?

© 2012 Citrix

•  Import signatures into NetScaler •  Signatures updates available from Citrix

•  Click and choose which application rules to apply

•  Choose whether to block or log
