ColdFusion security features
ColdFusion
provides scalable, granular security for building and deploying
your ColdFusion applications.
ColdFusion provides the following types of security resources:
- Development
- ColdFusion Administrator is password-protected. Additionally, you
can specify a password for access to data sources from Dreamweaver.
For more information on configuring Administrator security passwords,
see the ColdFusion Administrator online Help.
- CFML features
- The
CFML language includes the following features that you can use to
enhance application security.
The cfqueryparam tag:
This tag helps prevent users from injecting malicious SQL expressions.
For more information on using this tag for database security, see Enhancing security with cfqueryparam,
Scriptprotect setting: This setting helps protect against
cross-site scripting attacks. You set this value with the ColdFusion
Administrator Enable Global Script Protection setting, in the Application.cfc
This.scriptprotect variable, or in the corresponding cfapplication tag scriptprotect attribute.
For more information on this feature, see cfapplication in the CFML Reference.
For information on Application.cfc see Defining the application and its event handlers in Application.cfc.
Encryption and hashing functions: The Encrypt, Decrypt, and Hash functions
let you select a secure algorithm for encrypting and decrypting
data or generating a hash “fingerprint.” You can select from among
several secure algorithms that underlying Java security mechanisms
support. For encryption, these include, AES, Blowfish, DES and Triple
DES. For more information, see the Encrypt, Decrypt, and Hash, functions in the CFML Reference.
Data validation tools ColdFusion includes a variety of tools
for validating form input and other data values, including ways
to ensure that users do not submit malicious form data. For information
on data validation see Validating Data;
for specific information on security and validation, see Security considerations.
- Resource/Sandbox
- The ColdFusion Administrator can limit access to ColdFusion
resources, including selected tags and functions, data sources,
files, and host addresses. In the Standard Edition, you configure
a single set of resource limitations that apply to all your ColdFusion
applications.
In the Enterprise Edition, you can have multiple
sandboxes, based on the location of your ColdFusion pages, each
with its own set of resource limitations. You can confine applications
to secure areas, thereby flexibly restricting the access that the
application has to resources.
- User
- ColdFusion
applications can require users to log in to use application pages.
You can assign users to roles (sometimes called groups); ColdFusion
pages can determine the logged-in user’s roles or ID and selectively
determine what to do based on this information. User security is
also called authentication and authorization security.
Note: You can also use the cfencode utility,
located in the cf_root/bin directory, to obscure ColdFusion pages
that you distribute. Although this technique cannot prevent persistent
hackers from determining the contents of your pages, it does prevent
inspection of the pages. The cfencode utility is
not available on OS X.
