    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 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

    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: The latest VMware Service Insertion and Guest Introspection technologies have been integrated. This 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), the network throughput has been made three times faster when compared with prior technology.

    Upgrade to supported paths: The Upgrade on activation feature only upgrades 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 detects 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, the computer is now created outside of the account and the agent is allowed 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:

    • Information about why process exclusion items are not functioning correctly is provided, enabling you to troubleshoot the issue and know which actions to take to resolve it.
    • The process exception configuration workflow has been improved 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 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.
    • Improved the time it takes to auto-activate guest VMs protected by the Deep Security Virtual Appliance in an NSX-T environment. This feature requires Deep Security Manager FR 2019-12-12 or newer releases.
    • Streamlined event management for improved agent performance.
    • Added the ability to enable or disable Common Scan Cache for each agent through a CLI command.
    • Enhanced the Malware Scan Failure event description to indicate the possible reason.

    Release date: December 07, 2020

    Build number: 20.0.0-1559

    New features

    Enhanced platform support

    • Windows 10 20H2

    Improved security

    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 resolves 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

    • Improved Deep Security Relay's performance by only checking packages that have been modified. DS-55527

    Release date: October 28, 2020

    Build number: 20.0.0.1337

    New features

    Upgrade to supported paths: The Upgrade on activation feature only upgrades 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 detects the newer version and complete the upgrade to the designated release.

    Enhancements

    • Added various executable files as trusted installers so they are automatically recognized by Application Control. SF03568205/SEG-85141/DS-54884
    • 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. DS-51800/DS-51879

    • Deep Security Agent crashed unexpectedly because it was unable to detect the Docker engine version on Windows Servers. DS-29590
    • Deep Security Manager reported a security update timeout because Deep Security Agent received exceptions at security updates. SEG-82072/DS-54720
    • There were detection issues with real-time Anti-Malware scans. DS-50286
    • Deep Security Manager sometimes showed the incorrect Log Inspection status. SEG-77081/DS-54719
    • When a re-transmission packet with new packets was sent, it sometimes produced an "Unsupported SSL Version" Intrusion Prevention event. DS-53144

    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 later by November 16, 2020. If you do not upgrade to Deep Security Agent 20.0.0-1337 or later, 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 or later 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, 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, the computer is now created outside of the account and the agent is allowed 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.

    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.

    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:

    • Information about why process exclusion items are not functioning correctly is now provided, so you can troubleshoot the issue and know which actions to take to resolve it.
    • The process exception configuration workflow has been improved 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.
    • Added support for Deep Security Agent delayed upgrade to reduce the Anti-Malware offline issue after triggering an upgrade.

    Resolved issues

    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:
      • Agent size requirements have increased, including a slightly larger installer package on most platforms.
      • All agent content is now installed on the computer being protected. Content remains unloaded on a computer until a plug-in is activated by a policy or by the manager console.
      • The agent is now much less dependent on relays because all plug-in installations use the content already installed with the agent. This mitigates plug-in install issues due to relay communications because plug-ins can be installed without a connection to a relay.

    Resolved issues

    • Deep Security Agent sometimes was unable to connect to the manager via proxies. DS-65929
    • Some customers encountered an issue when the run-time CPU number was larger than expected, which led to crashes. DS-65757
    • Deep Security Agent sometimes showed package signature errors during an upgrade because of a mismatched Certification Revocation List (CRL). DS-65056

    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 resolves 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

    • Improved Deep Security Relay's performance by only checking packages that have been modified. DS-55527
    • Improved Deep Security Agent to better support Activity Monitoring on Trend Micro Cloud One - Workload Security. For more information, see Enable Activity Monitoring. DS-55230
    • Enhanced memory usage to improve performance. DS-53012

    Resolved issues

    • On Solaris servers where Integrity Monitoring was enabled and the rule: "Unix - Monitor Processes Running From '/tmp' Directories (ATT&CK T1059)" was assigned, a rule compile error was generated that referenced an "Unsupported Feature in Integrity Monitoring Rule". DS-55884

    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

    Deep Security Agent 20.0.0-1304 (20 LTS Update 2020-10-21)

    Release date: October 21, 2020

    Enhancements

    • Updated the Integrity Monitoring scan completion time in Deep Security Manager events to display in seconds with a thousands separator. DS-54680

    Resolved issues

    • Deep Security Manager reported a security update timeout because Deep Security Agent received exceptions at security updates. SEG-82072/DS-54720
    • Deep Security Manager sometimes showed the incorrect Log Inspection status. SEG-77081/DS-54719

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

    • 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. DS-51800
    • Integrity Monitoring detects changes to the "setuid" and "setgid" attributes for Linux and Unix platforms. DS-52061

    Resolved issues

    • Anti-Malware directory exclusion with wildcards didn't match subdirectories correctly. DS-50245
    • Deep Security Agent crashed on Solaris 10 during upgrades. SEG-72634/SF02975849/DS-49295
    • When Integrity Monitoring was enabled, the owner of a file was incorrectly changed to a user that did not exist. DS-52058

    Deep Security Agent 20 (long-term support release)

    Release date: July 30, 2020

    Build number: 20.0.0.877

    New features

    Improved security

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

    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.

    Improved quality and management

    Upgrade to supported paths: The Upgrade on activation feature only upgrades 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.

    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:

    • Information about why process exclusion items are not functioning correctly is now provided, so you can troubleshoot the issue and know which actions to take to resolve it.
    • The process exception configuration workflow has been improved to make it more robust.

    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.

    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.
    • 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.
    • Streamlined event management for improved agent performance.
    • Added the ability to enable or disable Common Scan Cache for each agent through a CLI command.
    • Added the ability for Deep Security Agent Anti-Malware to scan compressed files no matter their data types when IntelliScan is disabled.

    Resolved issues

    • After upgrading the Deep Security Agent, the "Sending Application Control Ruleset Failed" error sometimes occurred. DS-49828
    • Application Control occasionally appeared offline when Application Control and Anti-Malware were enabled at the same time.
    • The displayed packet header data contained redundant payload data. DS-45792
    • Memory leaked during SSL decryption because of a flaw in the SSL processing. SEG-68263/DS-44360
    • On specific Deep Security Agent servers the CPU usage spiked to 100% and pattern merges failed during the active update process. SEG-66210/02711299/DS-46429
    • When a security update was triggered before Anti-Malware was ready, the security updates failed. DS-36952
    • When real-time Integrity Monitoring was enabled with the rule "1002875: Unix Add/Remove Software" applied, the RPM database potentially locked. SEG-67275/SF02663756/DS-48524
    • Web Reputation, Firewall, Intrusion Prevention, and Log Inspection couldn't be enabled correctly when the system locale was set to Turkish. SEG-71825/SF03021819/DS-48916
    • Incorrect linking of certain libraries could lead to Deep Security Agent instability. SEG-72958/03071960/DS-49324
    • Anti-Malware directory exclusion with wildcard didn't match subdirectories correctly. SF03131855/SEG-74892/DS-50245
    • High CPU use occurred when Application Control was enabled and the host application was creating a high volume of non-executable files. SF02179544/SEG-55745/DS-41142
    • Non-executable files that were opened with execute permissions resulted in security events and drift that should not have been generated. SF01780211/SEG-46616/DSSEG-3607
    • Deep Security Agent did not add Python extension module (PYD) files to the inventory of Application Control. SF01804378/SEG-47425/DS-33690
    • Unicode user names could not be displayed in real-time Integrity Monitoring file scan events. SF02187371/SEG-56645/DS-39398
    • The Deep Security Agent network engine crashed because the working packet object was deleted accidentally. SF01526046/SF02159742/SEG-55453/DS-38812
    • The ds_agent process would sometimes crash under certain conditions when Integrity Monitoring was enabled. SEG-50728/DS-35446
    • Deep Security Agent sent invalid JSON objects in response to Deep Security Manager, which caused errors in Deep Security Manager's log file. SF01919585/SEG-48728/DS-34022
    • The "Send Policy" action failed because of a GetDockerVersion error in Deep Security Agent. SF1939658/SEG-49191/DS-34222
    • When multiple Smart Protection Servers were configured, the Deep Security Agent process would sometimes crash due to an invalid sps_index. SF01415702/SEG-42919/DS-33008
    • For Web Reputation, Deep Security Agent sent the incorrect credentials to the proxy, which returned HTTP 407. (SF01704358/SEG-45004/DS-32077)
    • Deep Security Agent's Intrusion Prevention module silently dropped zero payload UDP packets. SEG-39711/DS-32799
    • Integrity Monitoring events showed an incorrect file path with Unicode encoding. SEG-45239/DS-33911
    • 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:

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

      5. MAC_EXCLUSIVE_LIST=XX:XX:XX:XX:XX,XX:XX:XX:XX:XX

    5. Save.
    6. 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 is not bypassed. If the exact string "MAC_EXCLUSIVE_LIST=" is not present at the beginning of the line, no interfaces are bypassed. DSSEG-4055
