8. 8 When to use SecureICA or SSL Relay Use SecureICA when: – Internal LAN / WAN / Intranet – Secure DOS or Win 16 access is necessary – Have older devices/ ICA clients that cannot be upgraded – Risk of “man-in-the-middle” attack is acceptable Use SSL Relay when: – Small number of MetaFrame servers to support (<5) – No need to secure access at DMZ – No need to hide server IP addresses, or NAT is used – Need end-to-end encryption of data between client and server Use SecureICA when: – Internal LAN / WAN / Intranet – Secure DOS or Win 16 access is necessary – Have older devices/ ICA clients that cannot be upgraded – Risk of “man-in-the-middle” attack is acceptable Use SSL Relay when: – Small number of MetaFrame servers to support (<5) – No need to secure access at DMZ – No need to hide server IP addresses, or NAT is used – Need end-to-end encryption of data between client and server

9. 9 When to use CSG or VPN Use Citrix Secure Gateway when: – Large number of servers to support – Want to hide internal network addresses – Want to secure from DMZ – Need two-factor authentication (in conjunction with NFuse) – Need non-intrusive client install i.e. access from Internet cafes Use a Virtual Private Network (VPN) when: – Need two-factor authentication – Need to create a secure pipeline for full (beyond ICA) network access – Need to create secure tunnels between sites – Want to secure from within DMZ – Access is normally via same workstation i.e. OK to install additional client – Want/need to use IPSEC Use Citrix Secure Gateway when: – Large number of servers to support – Want to hide internal network addresses – Want to secure from DMZ – Need two-factor authentication (in conjunction with NFuse) – Need non-intrusive client install i.e. access from Internet cafes Use a Virtual Private Network (VPN) when: – Need two-factor authentication – Need to create a secure pipeline for full (beyond ICA) network access – Need to create secure tunnels between sites – Want to secure from within DMZ – Access is normally via same workstation i.e. OK to install additional client – Want/need to use IPSEC
