IMPORTANT: RDS activities are performed using Amazon's Relational Database Service engine, therefore, administering Amazon RDS requires a valid Access Key ID and Secret Access Key.

Description: Revokes ingress to a DB Security Group for previously authorized IP ranges or EC2 Security Groups.

Practical Usage

Used to revokes access to a DB Security Group for a range of IP addresses.

Connection Parameters

Property

Type

Required

Default

Markup

Description

Connection

 

 

 

 

Indicates where Amazon Web Service user credentials and preferences should originate from. This is a design mode parameter used only during task construction and configuration, thus, comprises no markup. The available options are:

  • Host (default) - Specifies that user credentials and/or advanced preferences are configured individually for this activity. This option is normally chosen if only a single activity is required to complete an operation.

  • Session - Specifies that user credentials and/or advanced preferences are obtained from a pre-configured session created in an earlier step with the use of the RDS - Create session activity. This option is normally chosen if a combination of related activities are required to complete an operation. Linking several activities to a single session eliminates redundancy. Additionally, a single task supports construction and simultaneous execution of multiple sessions, improving efficiency.

Session

Text

Yes if connection is session-based

RDSSession1

SESSION="RDSSession1"

The name of an existing session to attach this activity to. This parameter is active only if the Connection parameter is set to Session. The default session name is 'RDSSession1'.

Access key

Text

Yes if connection is host-based

(Empty)

ACCESSKEY=

"022QF06E7MXBSH9DHM02"

A 20-character alphanumeric string that uniquely identifies the owner of the AWS service account, similar to a username. This key along with a corresponding secret access key forms a secure information set that AWS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host.

Secret Access key

Text

Yes if connection is host-based

(Empty)

SECRETKEY=

"kWcrlUX5JEDGM/LtmEENI/

aVmYvHNif5zB+d9+ct"

A 40-character string that serves the role as password to access the AWS service account. This along with an associated access key forms a secure information set that EC2 uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host.

User agent

Text

No

AutoMate

USERAGENT="AutoMate"

The name of the client or application initiating requests to AWS. The default value is 'AutoMate'. 

Maximum retry on error

Number

No

(Empty)

MAXERRORRETRY="4"

The total amount of times this activity should retry its request to the server before returning an error. Network components can generate errors anytime in the life of a request, thus, implementing retries can increase reliability. 

Service URL

Text

No

(Empty)

SERVICEURL=

"https://rds.eu-west-1.amazonaws.com"

The URL that provides the service endpoint. To make the service call to a different region, you can pass the region-specific endpoint URL. For example, entering  https://rds.us-west-1.amazonaws.com points to US West (Northern California) region. A complete list of EC2 regions, accompanying endpoints and valid protocols can be found below under RDS Endpoints and Regions.

Proxy host

Text

No

(Empty)

PROXYHOST="proxy.host.com"

The host name (e.g., server.domain.com) or IP address (e.g., xxx.xxx.xxx.xxx) of the proxy server to use when connecting to AWS.  

Proxy port

Number

No

(Empty)

PROXYPORT="1028"

The port that should be used to connect to the proxy server.

Proxy username

Text

No

(Empty)

PROXYUSER="username"

The username that should be used to authenticate connection with the proxy server (if required).

Proxy password

Text

No

(Empty)

PROXYPWD="encrypted"

The password that should be used to authenticate connection with the proxy server (if required).

Signature method

Text

No

(Empty)

SIGNMETHOD="HmacSHA256"

The signature method to use for signing the request. This provides a valid hashing algorithm for signature calculation. Valid AWS signature methods are HmacSHA1 and HmacSHA256.

Signature version

Number

No

(Empty)

SIGNVERSION="2"

The signature version for signing the request. Valid AWS signature versions are 2 and 4. The difference with version 4 is that it allows you to sign your message using a key that is derived from your secret access key rather than using the secret access key itself.

Security Group Parameters

Property

Type

Required

Default

Markup

Description

Group name

Text

Yes

(Empty)

SECURITYGROUP="mydbgroup"

The name of the Amazon RDS security group in which to revoke access.

CIDRIP

Number

No

(Empty)

CIDRIP="192.168.100.100/0"

If enabled, specifies the IP range to allow access. Must be a valid Classless Inter-Domain Routing (CIDR) range in the format xxx.xxx.xxx.xxx/x (i.e.,192.168.100.100/0). If this parameter is enabled, the EC2 Security Group parameter becomes inactive.

EC2 security group

 

 

 

 

If enabled, specifies the Security Group Name and Owner ID to allow access. If this parameter is enabled, the CIDRIP parameter becomes inactive. This is a design time parameter and contains no markup.

Name

Text

No

(Empty)

EC2GROUP="mysecuritygrp"

The name of the Amazon EC2 security group in which to revoke access (e.g., mydbsecuritygroup). This parameter is active only if the EC2 Security Group option is selected. Must be entered along with Owner ID.

Owner ID

Number

No

(Empty)

EC2OWNERID=123456789012

The AWS account number of the owner of the EC2 security group in which to revoke access. This parameter is active only if the EC2 Security Group option is selected. Must be entered along with Name parameter.

Create and populate dataset with RDS Security group information

Text

No

(Empty)

RESULTDATASET="myDataset"

The name of the dataset to be created and populated with the RDS security group information. More information regarding the individual fields this dataset creates can be found below under Datasets.

Description tab - A custom description can be provided on the Description tab to convey additional information or share special notes about a task step.

Error Causes tab - Specify how this step should behave upon the occurrence of an error. (Refer to Task Builder > Error Causes Tab for details.)

On Error tab - Specify what AWE should do if this step encounters an error as defined on the Error Causes tab. (Refer to Task Builder > On Error Tab for details.)
