Cloudera Navigator Key HSM is a universal hardware security module (HSM) driver that translates between the target HSM platform and Cloudera Navigator Key Trustee Server. Navigator Key HSM allows you to use a Key Trustee Server to securely store and retrieve encryption keys and other secure objects, without being limited solely to a hardware-based platform. You must install Key HSM on the same host as Key Trustee Server. See Data at Rest Encryption Requirements for more information about encryption and Key HSM requirements. Set up the Key HSM repository. Download the Key HSM tarball and create a local Key HSM repository with the files from the tarball. You must create an internal repository to install Cloudera Navigator Key HSM. For instructions on creating internal repositories, see Configuring a Local Package Repository. Install the Key HSM repository. Add the local Key HSM repository you created in Step 1. See Configuring a Local Package Repository for more information. Run the following command to import the GPG key:$ sudo rpm --import Install the CDH repository. Key Trustee Server and Key HSM depend on the bigtop-utils package, which is included in the CDH repository. For instructions on adding the CDH repository, see Configuring a Local Package Repository. Install Navigator Key HSM. Run the following command to install the Navigator Key HSM package:sudo yum install keytrustee-keyhsm Cloudera Navigator Key HSM is installed to the /usr/share/keytrustee-server-keyhsm directory by default.

In dmesg. To show which ACL rules are required, perform the following steps: Save the dmesg content to a file:sudo dmesg > /tmp/dmesg.txt Use the dmesg.txt file content as input to the deny2allow command to analyze the action="denied" messages and display a list of required ACL rules based on the action="denied" messages. Here is an example command and output:$ sudo /usr/sbin/navencrypt deny2allow /tmp/dmesg.txtALLOW @mysql employees/* /usr/sbin/mysqldALLOW @mysql * /bin/bashALLOW @mysql * /bin/ls If you need to clear the dmesg log and start fresh, run dmesg -c. If a rule is displayed in the output from the command, it does not automatically mean the ACL rule must be added. You must determine which rules are actually needed. For example, the rule for ls would not typically be added as an ACL rule. After the initial ACL rules are created, disable permissive mode with the following command:sudo /usr/sbin/navencrypt set --mode=enforcing Adding ACL Rules Rules can be added one at a time using the command line or by specifying a policy file containing multiple rules. The following example shows how to add a single rule using the navencrypt acl --add command:sudo /usr/sbin/navencrypt acl --add --rule="ALLOW @mysql * /usr/sbin/mysqld" See Listing Categories for instructions on viewing existing categories. The following example shows how to add multiple rules using a policy file:sudo /usr/sbin/navencrypt acl --add --file=/mnt/private/acl_rules The contents of the policy file should contain one rule per line. For example:ALLOW @mysql * /usr/sbin/mysqldALLOW @log * /usr/sbin/mysqldALLOW @apache * /usr/lib/apache2/mpm-prefork/apache2 Navigator Encrypt releases 3.10 and higher support comments in the policy file. Comments begin with the hash (#) symbol. You can use comments to annotate the policy file, or to temporarily disable a rule for testing. For example: # Cloudera Navigator Encrypt policy file# Allow mysqld to access all database filesALLOW @mysql * /usr/sbin/mysqld# Allow mysqld to write logsALLOW @log * /usr/sbin/mysqld# ALLOW @apache * /usr/lib/apache2/mpm-prefork/apache2 Using a policy file is the fastest way to add multiple rules because it only requires the security key one time. It is also possible to overwrite the entire current rules set with the option --overwrite. When this command is executed, all current rules are replaced by the ones specified in the file that contains the new set of rules. Cloudera recommends to save a copy of your current set of rules by printing it with the option --print. Here is an example command using the --overwrite option:sudo /usr/sbin/navencrypt acl.

Hi CDH, Cloudera Manager, and Cloudera Navigator users,We’re pleased to announce the release of Cloudera Enterprise 5.4 (comprising CDH 5.4, Cloudera Manager 5.4, and Cloudera Navigator 2.3).Cloudera Enterprise 5.4 (Release Notes) reflects critical investments in a production-ready customer experience through governance, security, performance and deployment flexibility in cloud environments. It also includes support for a significant number of updated open standard components–including Apache Spark 1.3, Impala 2.2, and Apache HBase 1.0 (as well as unsupported beta releases of Hive-on-Spark data processing and OpenStack deployments).Recently Cloudera made the upgrade process considerably easier via an improved CDH upgrade wizard; see details about that wizard here and best practices here. (Note: Due to metadata format changes in Apache Hadoop 2.6, upgrading to CDH 5.4 and later from any earlier release requires an HDFS metadata upgrade, as well. Note also that for parcel-based installs of CDH 5.4, Cloudera Manager 5.4 is required.)SecuritySSL and Kerberos support in Apache Flume for the Thrift source and sink.SSL support across Cloudera Search (Solr and all integrations with CDH).Cluster-wide redaction of sensitive data in logs is now possible.HBase impersonation in Hue allows your client to authenticate to HBase as any user, and to re-authenticate at any time.Solr metadata stored in ZooKeeper can now be protected by ZooKeeper ACLs.Kerberos is now supported for Apache Sqoop2.PerformanceIncludes beta release of Hive-on-Spark as an option for improved Hive data processing performance (unsupported).MultiWAL support for HBase RegionServers allows you to increase throughput when a region writes to the write-ahead log (WAL).You can now store medium-sized objects (MOBs) up to 10MB in size directly in HBase while maintaining read and write performance.A new Kafka connector for Spark Streaming avoids the need for the HDFS WAL.Hue pages render much faster.Data Management and GovernanceExpanded coverage in Cloudera NavigatorImpala (CDH 5.4 and higher) lineageCloudera Search (CDH 5.4 and higher) auditingAuditing of Navigator activity, such as audit views, metadata searches, and policy editingAvro and Parquet schema inferencePlatform enhancementsRedesigned metadata search provides autocomplete, faster filtering, and saved searchesSAML for single sign-onCloud DeploymentsOpenStack deployments are now possible as an unsupported beta.HBase support on Microsoft Azure.Real-Time ArchitectureCloudera Distribution of Apache Kafka 1.3 installs by default and is supported for production use.Spark Streaming now has a receiver-less “direct” connector for Kafka.New or Updated Open Source ComponentsApache Hadoop 2.6Apache HBase 1.0Apache Hive 1.1Apache Oozie 4.1Apache Solr 4.10.3Apache Spark 1.3Cloudera Distribution of Apache Kafka 1.3Hue 3.7Impala 2.2Kite SDK 1.0New/Updated OS & Java SupportRHEL 6.6/CentOS 6.6/OEL 6.6 (UEK3)JDK8u40, JDK7u75Over the next few weeks, we’ll publish blog posts that cover some of these features in detail.

Managing the Access Control List Cloudera Navigator Encrypt manages file system permissions with an access control list (ACL). This ACL is a security access control created by Cloudera that enables a predefined Linux process to access a file or directory managed by Navigator Encrypt. The ACL uses rules to control process access to files. The rules specify whether a Linux process has access permissions to read from or write to a specific Navigator Encrypt path. A rule is defined in the following order:# TYPE @CATEGORY PATH PROCESS PARAMETERS The following table defines the ACL rule components:Table 1. ACL Rule Components Component Description TYPE Specifies whether to allow or deny a process. It can have either of the following values: ALLOW or DENY. @CATEGORY This is a user-defined shorthand, or container, for the encrypted dataset that the process will have access to. For example, if you are encrypting the directory /var/lib/mysql, you could use the category @mysql to indicate that this rule is granting access to a process on the MySQL data. See Listing Categories for instructions on viewing existing categories. PATH Specifies the rights permissions of a specific path. For example: *, www/*.htaccess. Omit the leading slash (/). PROCESS Specifies the process or command name for the rule. PARAMETERS Tells the process the parent-child process to be executed: --shell defines the script for Navigator Encrypt to allow for executable process. Supported shells are /usr/bin/bash, /bin/bash, /usr/bin/dash, and /bin/bash. --children defines for Navigator Encrypt which child processes to allow that are executed by a process/script. Example: --shell=/bin/bash, --children=/bin/df,/bin/ls All rules are stored in an encrypted policy file together with a set of process signatures that are used by Navigator Encrypt to authenticate each Linux process. This file is encrypted with the Navigator Encrypt key you defined during installation. Cloudera recommends using permissive mode to assist with the initial ACL rule creation for your environment. In permissive mode, Navigator Encrypt allows full access to the encrypted data by all processes, but logs them in dmesg as action="denied" messages. Consult these messages to identify required ACL rules. To set Navigator Encrypt to permissive mode, use the following command:sudo /usr/sbin/navencrypt set --mode=permissive To view the current mode, run navencrypt status -d. For more information on access modes, see Access Modes. deny2allow After you generate the action="denied" messages, use the navencrypt deny2allow command to show which ACL rules are required, based on the action="denied" messages.

Using a hardware security module with Navigator Key Trustee Server requires Key HSM. This service functions as a driver to support interactions between Navigator Key Trustee Server and the hardware security module, and it must be installed on the same host system as Key Trustee Server. Prepare Existing Keys for MigrationIn this procedure, you are prompted to migrate any existing keys from the Key Trustee Server to the HSM. Successful migration depends on the existing keys conforming to the following constraints: Key names can begin with alpha-numeric characters only Key names can include only these special characters: Hyphen - Period . Underscore _ To prepare for migration, check your key names and do the following if any of them are non-conforming: Decrypt any data using the non-conforming key. Create a new key, named as desribed above. Re-encrypt the data using the new key. Both Key HSM and Key Trustee Server must be set up and running. See Installing Cloudera Navigator Key HSM for details. Establish Trust from Key HSM to Key Trustee Server. This step assumes that Key Trustee Server has a certificate for TLS (wire) encryption as detailed in Managing Key Trustee Server Certificates. Key HSM service must explicitly trust the Key Trustee Server certificate (presented during TLS handshake). To establish this trust, run the following command:sudo keyhsm trust /path/to/key_trustee_server/cert The /path/to/key_trustee_server/cert in this command (and in the commands below) depends on whether the Key Trustee Server uses the default certificate (created by default during install), or uses a custom certificate (obtained from a commercial or internal CA). The two alternate paths are shown in the table below. The custom path is a common example but may differ from that shown. Default Custom /var/lib/keytrustee/.keytrustee/.ssl/ssl-cert-keytrustee.pem /etc/pki/cloudera/certs/cert-file.crt /var/lib/keytrustee/.keytrustee/.ssl/ssl-cert-keytrustee-pk.pem /etc/pki/cloudera/private/private-key.key Integrate Key HSM and Key Trustee Server. The following steps assume that both Key HSM and the Key Trustee Server are on the same host system, as detailed in Installing Cloudera Navigator Key HSM. These steps invoke commands on the Key HSM service and the Key Trustee Server, and they must be run on the host—they cannot be run remotely from another
