CA5377: Use container level access policy (code analysis) - .NET

Container level policy is not set when generating a service Shared Access Signature (SAS).

By default, this rule analyzes the entire codebase, but this is configurable.

A container-level access policy can be modified or revoked at any time. It provides greater flexibility and control over the permissions that are granted. For more information, see Define a stored access policy.

Specify a valid group policy identifier when generating the service SAS.

It is safe to suppress this rule if you're sure that the permissions of all resources are as restricted as possible.

If you just want to suppress a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.

#pragma warning disable CA5377
// The code that's violating the rule is on this line.
#pragma warning restore CA5377

To disable the rule for a file, folder, or project, set its severity to none in the configuration file.

[*.{cs,vb}]
dotnet_diagnostic.CA5377.severity = none

For more information, see How to suppress code analysis warnings.

Use the following options to configure which parts of your codebase to run this rule on.

• Exclude specific symbols
• Exclude specific types and their derived types

You can configure these options for just this rule, for all rules they apply to, or for all rules in this category (Security) that they apply to. For more information, see Code quality rule configuration options.

You can exclude specific symbols, such as types and methods, from analysis by setting the excluded_symbol_names option. For example, to specify that the rule should not run on any code within types named MyType, add the following key-value pair to an .editorconfig file in your project:

dotnet_code_quality.CAXXXX.excluded_symbol_names = MyType

Note

Replace the XXXX part of CAXXXX with the ID of the applicable rule.

Allowed symbol name formats in the option value (separated by |):

• Symbol name only (includes all symbols with the name, regardless of the containing type or namespace).
• Fully qualified names in the symbol's documentation ID format. Each symbol name requires a symbol-kind prefix, such as M: for methods, T: for types, and N: for namespaces.
• .ctor for constructors and .cctor for static constructors.

Examples:

You can exclude specific types and their derived types from analysis by setting the excluded_type_names_with_derived_types option. For example, to specify that the rule should not run on any methods within types named MyType and their derived types, add the following key-value pair to an .editorconfig file in your project:

dotnet_code_quality.CAXXXX.excluded_type_names_with_derived_types = MyType

Note

Replace the XXXX part of CAXXXX with the ID of the applicable rule.

Allowed symbol name formats in the option value (separated by |):

• Type name only (includes all types with the name, regardless of the containing type or namespace).
• Fully qualified names in the symbol's documentation ID format, with an optional T: prefix.

Examples:

At present, the following pseudo-code sample illustrates the pattern detected by this rule.

using System;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;

class ExampleClass
{
    public void ExampleMethod(SharedAccessBlobPolicy policy, SharedAccessBlobHeaders headers, Nullable<SharedAccessProtocol> protocols, IPAddressOrRange ipAddressOrRange)
    {
        var cloudAppendBlob = new CloudAppendBlob(null);
        string groupPolicyIdentifier = null;
        cloudAppendBlob.GetSharedAccessSignature(policy, headers, groupPolicyIdentifier, protocols, ipAddressOrRange);
    }
}

using System;
using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;

class ExampleClass
{
    public void ExampleMethod(SharedAccessBlobPolicy policy, SharedAccessBlobHeaders headers, Nullable<SharedAccessProtocol> protocols, IPAddressOrRange ipAddressOrRange)
    {
        CloudAppendBlob cloudAppendBlob = new CloudAppendBlob(null);
        string groupPolicyIdentifier = "123";
        cloudAppendBlob.GetSharedAccessSignature(policy, headers, groupPolicyIdentifier, protocols, ipAddressOrRange);
    }
}

CA5375: Do not use account shared access signature

CA5376: Use SharedAccessProtocol HttpsOnly
