#----------------
# List of hosts - use full host name
# host destination.example.com
#----------------
# host <REDIRECT HOST>.<REDIRECT DOMAIN>
#------------------------------------------------------------------
# List of domains. A <DOMAIN NAME> matches across hosts - for example
# domain example.com will match both host.internal.example.com and
# host.external.example.com

12. Apps Web - Cookie Domain Scoping
• Defines scope of cookie sharing to
avoid unnecessary exposure
• Prevents EBS session cookie from
getting hijacked
• Controlled by profile option - Oracle
Applications Session Cookie Domain
• Set this to HOST for DMZ

13. Apps –Password Hashing
SQL> select
ENCRYPTED_FOUNDATION_PASSWORD, ENCRYPTED_USER_PASSWORD
from fnd_user where user_name ='SYSADMIN‘

14. Apps – New Password Hash
• Enable Nonreversible hashing for
passwords
• SHA1 is replaced by SHA256, SHA384 &
SHA512
• Use AFPASSWD utility to migrate to new
and more secure hash algos
SQL> select
FND_WEB_SEC.GET_PWD_ENC_MODE from
dual;

15. Apps – Harden Passwords

16. Apps – Passwords handling
• Use secureapps option of startup
shutdown scripts
• Avoids use of apps db account
• Allows separation of duties

17. Apps - TLS
• Enable TLS Between Web Server and Client Browser
• TLS is successor to SSL and TLS 1.2 is the current
recommend protocol
• Make sure to disable SSLv2 & SSLv3
SSLProtocol All -SSLv2 -SSLv3
SSLCipherSuite HIGH:MEDIUM:!aNULL:!RC4:+HIGH:+MEDIUM
• SHA1 based certs are deprecated, Migrate to SHA2
based certs
• LetsEncrypt - Free SSL Certs
https://blog.pythian.com/using-letsencrypt-certs-oracle-e-
business-suite/

18. Apps - DMZ
• Activate Server Security - Secure Flag
in DBC
• Set the NODE_TRUST_LEVEL profile
for Server
• Restrict Responsibilities by setting
Responsibility Trust Level profile at
resp level

19. Apps - DMZ

20. DB – Encrypt SQL Traffic
• As of Oracle E-Business Suite Release
12, all components are encryption
compatible
• ANO is free with Enterprise Edition
• Just need to add these 2 lines to
$TNS_ADMIN/sqlnet_ifile.ora on the DB
SQLNET.ENCRYPTION_SERVER = REQUIRED
SQLNET.ENCRYPTION_TYPES_SERVER= (AES256, AES192,
3DES168)

21. Apps security references
• Security Configuration and Auditing Scripts for
Oracle E-Business Suite (Doc ID 2069190.1)
–Set of SQL and shell scripts that generate
