Deep Security Agent 20.0.0-1559 (20 LTS Update 2020-12-07)

Release date: December 07, 2020

Build number: 20.0.0-1559

New features

TLS Directionality: The manager heartbeat port can now act as both a TLS client and TLS server. Future agents will connect as TLS clients, not TLS servers. This will resolve issues with agent-initiated connections through a proxy or firewall that requires TLS sessions to be initiated in the same direction as the TCP layer of the connection.

Enhancements

Security updates were not automatically performed on new machines. SEG-91484/SF03828068/DS-57688

Notice

In this agent update there is a change to how the validation of the TLS certificate used for agent-manager communication is implemented. If you see the following warning during agent activation:

[Warning/2] | SSLVerifyCallback() - verify error 20: unable to get local issuer certificate

The most likely root cause is that agent cannot validate the certificate being presented to it by the manager. Pinning a trusted certificate is optional, so you can ignore this error if it doesn't apply to you. However, if you'd like to use a trusted certificate, follow the steps in Import a Deep Security Manager certificate chain issued by a public CA before activating the Deep Security Agent.

Deep Security Agent 20.0.0-1194 (20 LTS Update 2020-10-05)

Release date: October 5, 2020

Build number: 20.0.0-1194

New features

Improved performance for real-time Anti-Malware scanning on Linux: Real-time Anti-Malware scans have been improved for Deep Security Agent on Linux, resulting in increased response time, faster processing, and reduced CPU usage. Previously, all files were scanned during read/write. Now, Anti-Malware scanning is more efficient and file scanning during write is deferred (the file is added to a queue and scanned in the background).

Differentiated platforms: Deep Security Manager can now distinguish between Red Hat and CentOS platforms and operations. DS-52682

Continued network scans: After migrating guest VMs to another ESXi host in the same cluster using vMotion, the Deep Security Virtual Appliance's network scans will now continue where they left off, without delay. This feature only applies if you are using NSX-T Data Center and guest machines are using a policy without network feature overrides. DS-50482

Enhancements

Real-time Integrity Monitoring explicitly matches the directory specified in the base directory. Previously, it matched all paths that started with the base directory. DS-52692
Integrity Monitoring detects changes to the "setuid" and "setgid" attributes for Linux and Unix platforms. DS-52061

Deep Security Agent 20 (long-term support release)

Release date: July 30, 2020

Build number: 20.0.0.877

New features

Enhanced platform support

Ubuntu 20.04 (64-bit)
Cloud Linux 8 (64-bit)
Debian Linux 10 (64-bit)
Oracle Linux 8 (64-bit)
SUSE Linux Enterprise Server 15 (64-bit)
Red Hat Enterprise Linux 8 (64-bit)
CentOS 8 (64-bit)

SystemD support: SystemD is a Linux service manager that allows services to declare dependencies, which can enforce load and unload sequences of kernel modules and other services. See Linux systemd support for information about which platforms are supported. (DS-37395)

Secure Boot support: Deep Security Agent supports additional Linux operating systems with Secure Boot enabled. For details, see Linux Secure Boot support.

Improved security

Agent integrity check: Deep Security verifies your signature on the Deep Security Agent to ensure that the software files have not changed since the time of signing.

Protect VMs in NSX-T environments: We have integrated the latest VMware Service Insertion and Guest Introspection technologies which enables you to protect your guest VMs using Intrusion Prevention, Web Reputation, Firewall, Integrity Monitoring and recommendation scans on NSX-T hosts with agentless protection.

Seamless network protection: Deep Security Manager now sends guest VMs' network configuration to all Deep Security Virtual Appliances that are under the same cluster. The effect is that the appliances can now maintain the protection of guest machines that use the network features during and after a vMotion migration from one ESXi host to another under the same cluster. This feature only applies to NSX-T environments where the guest machine is using an assigned policy without network features overrides.

SELinux Support: Security-Enhanced Linux (SELinux) enforcing mode is supported on Red Hat Enterprise Linux 7 and Red Hat Enterprise Linux 8. Deep Security Agent is compatible with the default SELinux policies. Anti-Malware software such as ds_agent is required to run in an unconfined domain in order to protect the system. Any additional SELinux policy customization or configuration might be block blocked or fail because of ds_agent.

SSL improvements: Deep Security supports handshake hello_request (rfc5246) and Extension encrypt_then_mac (rfc7366) in SSL inspection.

Continuous Anti-Malware protection: Deep Security Manager now sends guest VMs' Anti-Malware real-time configuration to all Deep Security Virtual Appliances that are under the same cluster. The effect is that the appliances can now maintain the protection of guest machines that use the Anti-Malware real-time feature during and after a vMotion migration from one ESXi host to another under the same cluster. This feature only applies to NSX-T environments.

Improved management and quality

Automate the upgrade of agents in your environment: Deep Security gives you the flexibility to decide if new agents, when activated, should be upgraded to a newer version if one is available. This can be particularly useful in cases where application teams are using older golden images containing a version of the agent that is out of date. Simply enable upgrade on activation, define the lineup of agents you want to use in your environment using Agent Version Control, and as older agents come online and activate they are automatically upgraded for you.

NSX-T Network Throughput improvement: By introducing the Data Plane Development Kit (DPDK), we've made the network throughput three times faster when compared with prior technology.

Upgrade to supported paths: The "upgrade on activation" feature will only upgrade the agent on the computer from the last two major releases. If the agent does not meet the criteria, you must upgrade the agent manually to a release within the last two major releases. Then the "upgrade on activation" feature will detect the newer version and complete the upgrade to the designated release.

Protection for AWS accounts with incorrect credentials: In the past, if your credentials were entered incorrectly for AWS accounts in Deep Security, the agent failed to activate. This might have occurred because the credentials were entered incorrectly or because, over time, the credentials changed without a corresponding update on Deep Security. To help ensure protection remains in place in this situation, which in many cases is a simple configuration error, we will now create the computer outside of the account and allow the agent to activate.

Instance Metadata Service Version 2 (IMDSv2) support: IMDSv2 is supported in this release. For details, see How does Deep Security Agent use the Amazon Instance Metadata Service?

Actionable recommendations for scan failures: The Deep Security Agent provides actionable information about why a scheduled malware scan has been cancelled, and the recommended actions that should be taken to remedy the failure. For more information, see Anti-Malware scan failures and cancellations.

Improved process exceptions: The process exception experience has been improved in the following ways:

We've provided information about why process exclusion items are not functioning correctly so you can troubleshoot the issue and know which actions to take to resolve it.
We've improved the process exception configuration workflow to make it more robust.

Enhancements

Integrity Monitoring detects changes to the "setuid" and "setgid" attributes for Linux and Unix platforms.
Improved the heartbeat handling for Amazon WorkSpaces deployments when the workspace sync feature is not turned on for the matching AWS connector.
Extended the scope of the If a computer with the same name already exists setting on Administration > System Settings > Agents to apply to existing unactivated computers. Previously, it only applied to existing activated computers.
Improved the Deep Security Agent activation experience in the following ways:

Enhanced the agent-initiated activation experience by displaying the activation status (for example, a success message or a message that explains a newer Deep Security Manager version is required) on Deep Security Manager.

After migrating guest VMs to another ESXi host in the same cluster using vMotion, the Deep Security Virtual Appliance's Anti-Malware real-time scans will now continue where they left off, without delay. This feature only applies to NSX-T environments.
Increased the scan engine's URI path length limitation.
Added the ability for Deep Security Agent Anti-Malware to scan compressed files no matter their data types when IntelliScan is disabled.
Enhanced Linux real-time Anti-Malware performance when executing a Docker pull command.

Deep Security Agent - 20.0.0-3288 (20 LTS Update 2021-10-28)

Release date: October 28, 2021

Build number: 20.0.0-3288

New features

Evolution of the agent installer: The Deep Security Agent installer now installs most agent content. This results in the following changes:

Action required: Customers participating in the Trend Micro XDR Activity Monitoring preview for Workload Security

This Deep Security Agent release includes required updates for the Trend Micro XDR Activity Monitoring preview. If you are currently participating in the preview, you must upgrade to Deep Security Agent 20.0.0-1337 (or a newer version) by November 16, 2020. If you do not upgrade to Deep Security Agent 20.0.0-1337 (or a newer version), Activity Monitoring data will stop being collected on November 16, 2020. For more information about XDR and Activity Monitoring, see Integrate Workload Security with XDR.

Deep Security Agent 20.0.0-1337 (and newer versions) uses a new network connection to send Activity Monitoring data to Trend Micro. The connection details can be found in Enable Activity Monitoring. Ensure that agent traffic to this destination is allowed so Activity Monitoring data can be sent to Trend Micro.

Known issues

While the Deep Security Relay is upgrading co-located or independent relays, the alerts "Anti-Malware protection is absent or out of date" and "Security Update: Security Update Check and Download Failed (Agent/Appliance error)" might occur for up to 20 minutes or longer before they're automatically resolved and the respective alerts cleared. For any subsequent Deep Security Agent upgrades to succeed, please wait for the Deep Security Relay alerts to clear automatically. DS-54056

Deep Security Agent 20 (long-term support release)

Release date: July 30, 2020

Build number: 20.0.0.877

New features

Improved security

Agent integrity check: Deep Security verifies your signature on the Deep Security Agent to ensure that the software files have not changed since the time of signing.

Protect AWS accounts with incorrect credentials: In the past, if your credentials were entered incorrectly for AWS accounts in Deep Security, the agent failed to activate. This might have occurred because the credentials were entered incorrectly or because, over time, the credentials changed without a corresponding update on Deep Security. To help ensure protection remains in place in this situation, which in many cases is a simple configuration error, we will now create the computer outside of the account and allow the agent to activate.

SSL improvements: Deep Security supports handshake hello_request (rfc5246) and Extension encrypt_then_mac (rfc7366) in SSL inspection.

Improved quality and management

Reboot requirement removed for agent upgrade: Previously, there were several situations where a Windows server would require a reboot for a new agent to complete the upgrade. The need to reboot when upgrading from Deep Security Agent 11.0, 12.0, or 20.0 on any Windows Operating System has been completely removed, enabling the application to not be impacted as result of upgrading Deep Security Agent.

Instance Metadata Service Version 2 (IMDSv2) support: IMDSv2 is supported with Deep Security Manager FR 2020-04-30. For details, see How does Deep Security Agent use the Amazon Instance Metadata Service?

Actionable recommendations for scan failures: The Deep Security Agent provides actionable information about why a scheduled malware scan has been canceled, and the recommended actions that should be taken to remedy the failure. For more information, see Anti-Malware scan failures and cancellations.

Anti-Malware real-time file scan report: Deep Security has the ability to determine the top 10 files that are scanned by Anti-Malware real-time scan. This provides a starting point for performance evaluating and tuning, as you can use this information to set file exclusions and avoid unnecessary scans. The 'AmTopNScan.txt' file with the collected data can be generated using the following methods:

By the command dsa_control --AmTopNScan
By the diagnostic service

Improved process exceptions: The process exception experience has been improved in the following ways:

We've provided information about why process exclusion items are not functioning correctly so you can troubleshoot the issue and know which actions to take to resolve it.
We've improved the process exception configuration workflow to make it more robust.

Windows Event Channel for Log Inspection: Windows Event Channel logging provides a new option for tracking OS and Application logging for Windows platforms newer than Windows Vista. Event channels can be used to collect Log Inspection events which you can view later.

Enhancements

Improved the heartbeat handling for Amazon WorkSpaces deployments when the workspace sync feature is not turned on for the matching AWS connector.
Removed Integrity Monitoring and Application Control's dependency on Anti-Malware, so they no longer require Anti-Malware to be installed to function.
Added the ability for Deep Security Agent Anti-Malware to scan compressed files no matter their data types when IntelliScan is disabled.
Added support for agentless mode on vCloud connector for version 9.5 or later.
Enhanced the agent-initiated activation experience by displaying the activation status (for example, a success message or a message that explains a newer Deep Security Manager version is required) on Deep Security Manager.
Enhanced the Malware Scan Failure event description to indicate the possible reason.
Streamlined event management for improved agent performance.
Added the ability to enable or disable Common Scan Cache for each agent through a CLI command.

Deep Security Agent 20.0.0-1337 (20 LTS Update 2020-10-28)

Release date: October 28, 2020

Build number: 20.0.0.1337

Resolved issues

When using Deep Security Agent on Solaris, the Integrity Monitoring port scanning feature did not work because the agent did not have access to information on the user ID under which a given port was opened. This prevented storage of any listening port information. The port scanning feature on Solaris agents has been modified to store the string "n/a" for the userid. This allows the remaining port information to be stored and used in the port scanning function. However, exclusions and inclusions based on User ID still do not function correctly because this information is not available. DS-53922

The interface isolation feature was still on when Firewall was turned off. (SEG-32926/DS-27099)
After applying rule 1006540, "Enable X-Forwarded-For HTTP Header Logging", Deep Security would extract the X-Forwarded-For header for Intrusion Prevention events correctly. However, a URL intrusion like "Invalid Traversal" would be detected in the HTTP request string before the header was parsed. The Intrusion Prevention engine has been enhanced to search X-Forwarded-For header after the header is parsed. (SEG-60728/DS-42332
Deep Security Agent sent invalid JSON objects in response to Deep Security Manager, which caused errors in Deep Security Manager's log file. (SEG-48728/SF01919585/DS-34022)
On Solaris servers with clusters, the Deep Security Intrusion Prevention module would come under heavy load while inspecting the clusters' private traffic. The extra load caused latency issues, node evictions, and loss of synchronization events.

You can now configure the Packet Processing Engine on the agent to bypass traffic inspection on a specified interface. Where a specific interface on a computer is dedicated to cluster private traffic, this configuration can be used to bypass inspection of packets sent to and received from this interface. This results in faster packet processing on the bypassed interface and other interfaces.

Use of this configuration to bypass traffic inspection is a security risk. It is up to you to determine if the benefit of reduced latency outweighs the risk involved. It is also up to you to determine whether only the nodes in the cluster have access to the subnet whose interface is being bypassed.

To implement the bypass, do the following:

Upgrade the Deep Security Agent to the latest build containing this fix.
Create a file under /etc directory named "ds_filter.conf".
Open the /etc/ds_filter.conf file.
Add the MAC addresses of all NIC cards used for cluster communication, as follows:

MAC_EXCLUSIVE_LIST=XX:XX:XX:XX:XX,XX:XX:XX:XX:XX

Save.
Wait 60 seconds for your changes to take effect.

In the /etc/ds_filter.conf file:

The MAC_EXCLUSIVE_LIST line must be the first line in the file.
All letters in the MAC address must be uppercase.
Leading zeros in each byte must be included.

Valid MAC_EXCLUSIVE_LIST:

MAC_EXCLUSIVE_LIST=0B:3A;12:F8:32:5E

MAC_EXCLUSIVE_LIST=0B:3A;12:F8:32:5E,6A:23:F0:0F:AB:34

Invalid MAC_EXCLUSIVE_LIST:

MAC_EXCLUSIVE_LIST=B:3A;12:F8:32:5E

MAC_EXCLUSIVE_LIST=0b:3a;12:F8:32:5e,6a:23:F0:0F:ab:34

MAC_EXCLUSIVE_LIST=0B:3A;12:F8:32:5E

If the MAC address is not valid, the interface will not be bypassed. If the exact string "MAC_EXCLUSIVE_LIST=" is not present at the beginning of the line no interfaces will be bypassed. (DSSEG-4055)
