Version 10.4.18

ClamAV

Disable ClamAV concurrent database reloads on memory-constrained systems, i.e. AXS Guard appliances with 2GB or less, which prevents these systems from going out of memory during pattern updates.

Version 10.4.17

SecureDNS

A reporting feature has been added to allow system administrators to get better insights into malicious DNS activity. Malicious DNS queries are classified by the threat they represent and are organized into 10 distinct threat categories. See Reports > Threats > Malware Detection.

SecureDNS logs are available under Network > DNS > SecureDNS logs. Hosts which generate unusual DNS traffic can be easily identified by their source IP address, allowing you to isolate them from your network for further investigation and troubleshooting.

SecureDNS reports will contain more details in future versions. The cause, source and requested destination FQDNs will also be mentioned, so stay tuned.

OpenVPN

A strict authentication option has been added to the OpenVPN server. If enabled, the server will verify if the CN or e-mail address in the client certificate matches the username provided during authentication. If they differ, the connection will be refused. This prevents sharing of client certificates.

Reverse Proxy

A Preserve Hostname option has been added to the Reverse Proxy configuration page. When enabled, the reverse proxy will be instructed to preserve the original Host: header from the client browser when constructing the proxied request to be sent to the target server. Enabling this option is mostly useful in special configurations like proxied mass name-based virtual hosting, where the original Host: header needs to be evaluated by the backend server.

Version 10.4.13

SecureDNS

SecureDNS protects users from inadvertently accessing malware, ransomware, malicious domains, botnet infrastructure and more. It is an essential component of cybersecurity.

Research by industry leaders indicates that more than 91% of malware attacks use DNS exploits in one way or another. Despite this, many organizations don't monitor DNS traffic, leaving them vulnerable to attacks.

SecureDNS is available for customers with a premium content scanning license. To use SecureDNS, activate the feature and then enable the option in Network => General.

IPS

HTTPS processing has been optimized. Established and safe HTTPS connections are no longer being further analyzed by the IPS in order to save AXS Guard system resources.

Directory Services

Active Directory synchronization has been improved by removing WINS dependencies. Operations now entirely rely on the Kerberos protocol. Note that the Kerberos server must be accessible. The clocks of AXS Guard and the Kerberos server must also be properly synchronized with a time server.

Anti-Malware & Web Content Scanning

Download threads

Downloads via the web content scanning engine have been optimized. Slow download threads are now being prevented from causing delays in accessing the AXS Guard Cloud threat protection service in favor of other, faster threads. The timeout for connecting to the AXS Guard cloud has also been reduced to 5 seconds.
High Availability

Improve support for HTTPS inspection. The HTTPS inspection certificate cache has been moved to the replicated DRBD filesystem, allowing it to be used more efficiently by the other cluster node. In the event of a failover, certificates will no longer have to be regenerated, as they are available and kept in sync on all HA nodes.
HTTPS Inspection

Clear the HTTPS inspection certificate cache when the built-in CA is reinitialized. The HTTPS inspection feature uses the built-in CA to build a cache of trusted server certificates.

These certificates are signed by the built-in CA, and are considered valid as long as the built-in CA is trusted by the user's browser.

However, when the built-in CA is reinitialized, all certificates residing in that cache will no longer be trusted by clients. For this reason, the cache is now also cleared when the built-in CA is being reinitialized.

Firewall

Adjust the fwd-edr firewall rule to allow connections to the ReaQta endpoint security service in the AXS Guard cloud.

E-mail

Fix 'out of office' messages. Out of office notifications stopped working after a regression in the previous AXS Guard version. This issue was related to the host domain name being used to configure 'out of office' message recipients in HA environments. Due to misconfiguration, the notifications could not be delivered.

PKI

Fix log warnings. Warnings are reported in the logs when a certificate is being imported without a certificate chain or when a certificate is missing the Common Name (CN) field.

System Administration Tool

Fix HTML escaping to prevent HTML injection. Other changes include corrections in labels, links, casing, descriptions and more.

VPN

OpenVPN Service

Prevent the AXS Guard OpenVPN service from accepting connections made by PAX clients. PAX clients can automatically use TCP port 443 as a fallback for UDP port 1194, e.g. when sitting behind a restrictive corporate firewall.

However, this port cannot be shared with the OpenVPN service, which will now deny PAX clients from establishing a successful connection when PAX and OpenVPN client certificates are signed by the same CA.
OpenVPN Client Configuration Export

Fix client configuration export with encrypted private key protection when the use deprecated ciphers option is enabled on the server side.

Version 10.4.12

Version 10.4.11

HTTP Reverse Proxy Access Control

System administrators now have the possibility to restrict access to applications and services based on the IP address of the remote client. This is especially useful for applications and websites where user authentication is not enforceable or desired.

OpenVPN System Legacy Options

The following options have been relocated in the OpenVPN Server configuration screen:

Allow Deprecated Ciphers
Use small Subranges
Accept Compressed Data

Note that these options are only present for legacy reasons, i.e. to support outdated client software and/or obsolete OpenVPN configurations. The use of obsolete server and client options is insecure. System administrators should upgrade old OpenVPN client software and configurations ASAP.

Personal AXS Guard

The PAX diagnostic tool has been refactored and improved, so system administrators can identify problems and detect network issues more easily.

Version 10.4.10

Trend Micro Antivirus

Resolve Bug #130743 - Antivirus : Ensure only one instance of trophie is running after upgrade to 10.4.9.

Prevent more than one trophie process to accept new connections for antivirus processing in order to avoid the use of outdated pattern files and HA failover issues.

On HA systems, failovers will not succeed as only one trophie process is terminated while others still hold references to the trophie socket residing on the DRBD filesystem. As long as this socket continues to exist, the DRBD filesystem will fail to unmount, stalling the HA failover.

Ignore the IP address of a DHCP device during the validation of a static route.

Reverse Proxy RDG

A new authentication policy was added, which supports logins with a back-end password, followed by a one-time password generated with either an OATH or DIGIPASS token (back-end password + OATH or DIGIPASS).

Version 10.4.1

Various improvements and software fixes

Version 10.4.1 contains various software fixes to improve the overall quality, stability and security of the AXS Guard appliance.

Contact support@axsguard.com for additional information.

Strong Authentication with Push Notifications for Web Applications

The AXS Guard reverse proxy now supports Push Notification Authentication.

Push Notification Authentication enables user authentication by sending a push notification directly to the user’s smartphone, alerting them that an authentication attempt is taking place.

Users can now use their mobile devices as the second required factor for secure two-factor authentication; there is no need for client-side tokens or additional devices.

When users log into a secured web application, they will automatically receive an authentication request based on their username. Users can then view the authentication details and approve or deny access, via the simple press of a button.

To use this feature, you need the mobile application, which can be personalized and branded according your requirements, a DIGIPASS server license, the AXS Guard Enterprise bundle and a web application to be secured.

Please note that in order to use this feature, some custom development is required. Contact sales@axsguard.com for more information.

Firewall Geo-blocking

Geo-blocking is a technology which limits Internet traffic based on geographic location. You determine whether users can access your network or application based on their specific location.

This new feature allows system administrators to easily block malicious traffic - such as automated cyberattacks & port scanners - coming from unauthorized locations. It can also be used to prevent users from accessing potentially dangerous and questionable services hosted abroad.

Geo-blocking is an effective tool to prevent your system logs from being flooded with unnecessary information and eases administrative burden.

AXS Guard NTP Cloud Service

A precise time is necessary to be able to efficiently compare log files between various IT systems, for example in the event of a security incident. Many AXS Guard services, such as 2FA, Kerberos and scheduled tasks also rely on a precise time.

AXS Guard has gone through the validation process and is now officially part of the global NTP network.

NTP stands for Network Time Protocol, and it is an Internet protocol used to synchronize the clocks of computers to some time reference. NTP is an Internet standard.

Reconfiguring the NTP settings of your computers is relatively easy. This setting can also be configured centrally so that you don’t have to manually reconfigure each and every individual computer in your network.

CEO Fraud Protection

CEO Fraud is a type of spear-phishing email attack.

Typically, attackers identify themselves as high-level executives (CFO, CEO, CTO, etc.), lawyers or other types of legal representatives and purport to be handling confidential or time-sensitive matters, attempting to trick staff into transferring money to a bank account they control.

The AXS Guard content scanning engine has been updated to detect and block such attacks more effectively.

System Updates and Improvements

EAP-MSCHAP v2 Support for SSTP Server

Support for the Extensible Authentication Protocol (EAP-MSCHAP v2) has been added to the AXS Guard SSTP server to improve security.

RDG Password Auto-learning

This reverse proxy feature already existed for HTTP back-ends, but has now also been implemented for Remote Desktop Gateways. It offers a better UX to end users and allows for a swifter integration of secure AXS Guard authentication methods, such as 2FA.

Network Connectivity Checks

Connectivity checking is a functionality which periodically tests whether the AXS Guard network interfaces still have connectivity or not. This option has been refactored in the web-based administrator tool for a better user experience.

OpenVPN and PAX Server

The server binding options have been refactored to improve the user experience. Administrators who are looking to (re)configure the PAX or OpenVPN service are now presented with a clear selection of binding options.

Semi-Persistent IP Addresses for OpenVPN Clients

The OpenVPN server has been updated to maintain a persistent list of IP addresses handed out to different clients. When a client reconnects at a later time, the IP address that was used previously will automatically be reassigned by the server.

Samba Updates

Samba is a standard Windows interoperability suite of programs used on AXS Guard. Various components of this suite have been upgraded to improve security for the following services:

System backups on network shares
Directory services & authentication (LDAP)

Documentation

The AXS Guard documentation is constantly updated to reflect the various changes and improvements in the software and the product as a whole. Documents are available in the PDF and HTML format.

Web Access

Correct the handling of Kerberos authentication failures for the proxy server, preventing the invocation of an excessive number of 'negotiate_kerberos_auth' helpers.

Webmail

Improve the general responsiveness of the webmail service when used by a large amount of concurrent users.

Version 10.3.12

Clarified instructions in License Wizard

The license wizard allows system administrators to upload a system license to the AXS Guard appliance, which is required to get it to full operational, in-service status.

The wizard now contains clearer instructions to guide administrators through the entire licensing process.

New authentication policies for VPN services

A second authentication factor can now be used in combination with one-time passwords generated by OATH (Google or Microsoft) authenticators.

DIGIPASS tokens already offered this possibility in the form of a PIN. However, this option was not available for users with an OATH authenticator.

To further strengthen the authentication process and allow greater flexibility in the deployment of strong authentication for VPN access, new authentication policies are now available for PPTP, L2TP and SSTP.

The 'PasswordAndOATHOrDIGIPASS' policy requires users to log in with their password and a one-time password generated by their OATH authenticator or DIGIPASS token.

The 'PasswordAndOATHorPasswordAndDIGIPASS' policy requires users to log in with their password and a one-time password generated by their OATH authenticator or with their password and a one-time password generated by their DIGIPASS token.

System Dashboard improvements

New badges have been introduced to indicate the status of various feature licenses. While hovering over them, more detailed license information will appear automatically.

A widget showing blocked users and hosts has also been added. This widget allows system administrators to unlock accounts and unblock hosts with greater ease, while providing additional details about the listed items.

Various VPN Fixes

The OpenVPN topology has been changed so that the full virtual IP range is available for VPN clients.

The number of pseudo-terminal devices for PPP tunnels has been increased to avoid client 'port' failures.

IP addresses allocated to clients by SSTP are now freed correctly after SSTP clients disconnect. This prevents premature depletion of the IP address pool.

Version 10.3.11

AXS Guard SSL Proxy Feature Release

The SSL filtering feature is no longer in its experimental phase and is now available for customers with a Premium Content Scanning license.

Information and configuration instructions pertaining to this new feature are available on this website (see system administration > web access).

Contact sales@axsguard.com to upgrade your existing content scanning license or to purchase a new license.

Fix SSTP Authentication Failures Make AXS Guard wait for LCP configuration requests from clients, rather than initiating them on the server side.

This avoids a race condition in (samba) PPP causing LCP configuration requests to stop prematurely and fail due to authentication proposals that were perceived as invalid.

Fix Firewall Policy Rendering Issue In some cases, very long firewall policy descriptions caused the browser to hide other policy data. The readability of the firewall policy page has been improved and the issue has been resolved.

Version 10.3.10

Transparent Proxy for SSL Inspection

Transparent proxies are commonly used to prevent users from abusing or bypassing company web access policies and to ease administrative burden, since no client-side browser configuration is required.

SSL Inspection can now be enabled transparently. If enabled, client traffic towards TCP port 443 will be intercepted and redirected to port 3130 for further processing.

For this to work seemlessly, the CA certificate used by the SSL proxy must be added as a trusted root CA on all clients that will be scanned.

Note that certain web applications may not function properly when decrypted. You may also want to exclude certain domains and networks for any other reason, including legal or privacy reasons, e.g. sites which provide online banking services.

For this purpose, the AXS Guard cloud service provides a global SSL exception list which will be available on all systems with a Premium Content Scanning license. We highly recommend using this list for best performance and results.

System Dashboard Improvements

All widgets will show dummy data when the dashboard is being loaded to avoid reported flickering and layout issues.

The basic system load information on the dashboard has been replaced by a more detailed system load graph, showing various system loads over time.

Version 10.3.9

Gradual rollout of the new SSL Inspection feature

Over the last few years, many popular web sites including Google, Youtube, Reddit and Facebook have started enabling HTTPS encryption by default.

This means that without configuring SSL inspection, proxies have limited filtering, monitoring and logging capabilities.

In this new version, we implemented support for man-in-the-middle SSL filtering, which will allow system administrators to more effectively control and monitor web traffic passing through the AXS Guard proxy server.

System Dashboard Improvements

The AXS Guard system dashboard represents key performance indicators and metrics and is constantly reworked based on customer feedback.

A tooltip showing IPsec tunnel status information has been added to the system dashboard to improve the user experience.

Personal AXS Guard logs are now grouped per client, allowing system administrators to locate various client logs with greater ease.

DNS over HTTPS

DNS over HTTPS is problematic for the analysis and monitoring of DNS traffic for cyber security purposes, as it can be used to bypass company content-control software and DNS policies.

Firefox implemented a mechanism to automatically disable or enable DNS over HTTPS based on a canary domain. This canary domain is enabled by default on AXS Guard to block DNS over HTTPS.

Also see the KB article on this site, which covers all client implementations (Knowledge Base > Networking).

Version 10.3.8

Export system metrics to AXS Guard cloud

Some important system metrics have been made available in the AXS Guard cloud so system administrators can easily access vital information pertaining to all their deployed systems in a secure fashion.

Add option to set SMTP authentication policy

AXS Guard can be intergrated into an Office 365 environment to scan all incoming and outgoing mail traffic for malicious content and viruses.

To allow AXS Guard to also scan outgoing messages, mail clients must be configured to use the AXS Guard SMTP server instead of the Office 365 SMTP server.

This will ensure that all outgoing mail traffic is logged by AXS Guard and that its mail policies can be enforced.

The new option allows system administrators to restrict user access to protect the AXS Guard MTA against brute-force attempts and to implement a more strict TLS policy.

Disable IP forwarding when license is expired

AXS Guard will automatically put itself in "safe mode" when its license expires. As the system will no longer be able to download critical software updates without a valid license, all Internet traffic will be blocked for security purposes.

Version 10.3.7

New System Dashboard

In the first version of the new dashboard, we represent the same data of the "old dashboard" using new and interactive widgets.

For the sake of convenience, the former dashboard can still be accessed.

The AXS Guard dashboard will remain a focus for improvement; administrators can expect a lot more interesting widgets and functionalities in the near future.

Previous versions

Various improvements and software fixes

Versions 10.3.1, 10.3.2, 10.3.3, 10.3.4, 10.3.5 and 10.3.6 contain small feature changes and software fixes to improve the overall quality, stability and reliability of the AXS Guard appliance.

Contact support@axsguard.com for details.

New Dashboard

The AXS Guard system dashboard has been reworked extensively to better represent key performance indicators and metrics.

In the first version, we represent the same data of the "old dashboard" with new and interactive widgets. For the sake of convenience, the former dashboard is still easily accessible.

In the next iteration, extra widgets will be added to adequately respresent information about the system’s disk usage, the status of IPsec tunnels and VPN client connections.

The AXS Guard dashboard will remain a focus for improvement; administrators can expect a lot more interesting widgets and functionalities in the near future.

New Features

Microsoft Azure Ready

The AXS Guard virtual appliance can now be easily deployed from within the Azure Market place to operate on the Microsoft Azure platform. AXS Guard integrates the Microsoft Azure Linux Agent which manages provisioning and Virtual Machine interaction with the Azure Fabric Controller.

Office 365 Fast Lane

According to a Computable Magazine article of 17 June 2019: "Office 365 issues with legacy networks" - excessive network latency causes major delays in Office 365 implementations. Additionally, 63% of 250 surveyed companies agree that project collaboration in an Office 365 environment suffers from network-related problems.

As a response to these complaints, Microsoft recommended its "ExpressRoute" solution, which allows companies to optimize their connection speeds for Microsoft cloud services. However, this solution is rather expensive and complex to configure, making it often prohibitive for SMEs.

This is why AXS Guard developed the "Office 365 Fast Lane" solution, a cheaper alternative that is technically similar. The solution consists of a simple setup wizard which allows system administrators to correctly configure firewall, security and other Office 365 network settings in no time.

This way, employees can benefit from faster, optimized Office 365 connection speeds and profit from the increased responsiveness of frequently-used Office 365 applications.

Optimal network speeds are calculated in function of the total available Internet bandwidth, which is automatically measured by AXS Guard. After completing the wizard, users will immediately notice the result.

E-mail filtering incorporates Google Safe Browsing

Google Safe Browsing helps to protect users on the internet against malicious sites by showing warnings when they attempt to visit such sites or download dangerous files.

AXS Guard integrates Google Safe Browsing as an extension to its adaptive e-mail filter. Every URL present in e-mails is processed by the AXS Guard cloud URL threat protection service (CTRS) using Google’s Safe Browsing technology. Messages containing potentially dangerous URLs will be marked as unsafe and quarantined.

Dynamic hostnames in IPsec tunnel definitions

Traditionally IPsec site-to-site tunnel definitions require fixed IP addresses for host identification and policy matching. In order to support IPsec tunnels for sites where one side has a dynamic IP address, AXS Guard can now be configured with a template or wild-card definition to accept any connection with the right credentials. Security-wise this is not an optimal solution. Furthermore it can cause a lot of unwanted log entries originating from unknown connections.

To address this issue, AXS Guard now supports the use of dynamic (DNS) hostnames, making tunnels definitions more secure. Every time a tunnel is (re)started, a DNS lookup of the hostname is performed to determine the IP address to connect to. When the tunnel collapses because one side changed its IP address, the tunnel is re-established automatically when that side updates its dynamic DNS entry with the new IP address.

Lists of local and remote subnets in IPsec tunnel definitions

IPsec site-to-site tunnels definitions share one local subnet with one remote subnet. In case that many local subnets have to be shared with possibly many remote subnets, multiple tunnel definitions have to be configured separately for each subnet sharing the same IPsec MAIN mode.

System administrators can now specify a list of local and remote subnets. This reduces configuration overhead and also simplifies IPsec VPN status management.

Personal AXS Guard Industrial AIO

The Personal AXS Guard portfolio of products has been extended with a new type of hardware geared towards industrial applications. The brand new Personal AXS Guard Industrial all-in-one device is based on an x86 64bits platform with two ethernet ports (LAN and WAN), an optional wireless-N adaptor, mSATA storage and is rack-mountable (DIN rail).

Create a new Personal AXS Guard client and select the AG-I122 (Industrial all-in-one) hardware type for an optimal configuration.

Version 10.2

Secure Socket Tunneling Protocol (SSTP)

AXS Guard extends its offering of remote access solutions with support for the Microsoft Secure Socket Tunneling Protocol (SSTP), a VPN service that provides a mechanism to transport PPP traffic over an SSL/TLS channel.

SSL and TLS are cryptographic protocols designed to provide communications security over a computer network.

The use of SSL/TLS over TCP port 443 allows SSTP clients to pass through virtually all firewalls and proxy servers, except for authenticated web proxies.

The SSTP server can be configured to enforce strong authentication, which is capable of blending different authentication factors and/or types for increased security.

The AXS Guard reverse proxy manages the SSTP server as a separate application, allowing administrators to share the same external IP address and port with other applications and services.

See the official Microsoft documentation for additional information about SSTP.

Documentation

The AXS Guard documentation is constantly updated to reflect the various changes and improvements in the software and the product as a whole. Documents are available in the PDF and HTML format.

Microsoft SSTP VPN Support

MS-SSTP (Microsoft Secure Socket Tunneling Protocol) is a VPN protocol which is developed by Microsoft. It implements PPP over HTTPS (SSL), so traffic can easily traverse firewalls and proxies.

CA Certificate Export Option

If the SSTP server certificate is signed by the AXS Guard CA, the CA certificate must be exported and added as a trusted root CA on each Windows SSTP client in order for connections to succeed. A new button has been added for this purpose.

OATH Support for Remote Desktop Gateway Back-ends

The Remote Desktop Gateway (RDG) reverse proxy back-end now supports authentication with OATH-based tokens, such as Google and Microsoft Authenticator apps.

The following authentication methods are available:

OATH (default)
DIGIPASS
OATH or DIGIPASS (to facilitate migration)
AXS Guard password
Back-end password (LDAP)

OATH is supported for all RDG implementations, such as RPC over HTTP (prior to Windows 8), RDG (Windows 8 or later) and the Microsoft Remote Desktop App (Android, iOS and Windows).

Version 10.1

OATH

Support for Google and Microsoft OATH tokens has been implemented. OATH tokens provide one-time passwords to end users and are a form of strong authentication.

The Initiative for Open Authentication (OATH) is a collaborative effort of IT industry leaders aimed at providing a reference architecture for universal strong authentication across all users and all devices over all networks. Using open standards, OATH will offer more hardware choices, lower cost of ownership, and allow customers to replace existing disparate and proprietary security systems whose complexity often leads to higher costs.

An OATH license is required for this feature.

Licensing

Tokens cannot be assigned without a valid license; a new system license is required. Contact your reseller to obtain an OATH token license.

Go to System > License > Authenticators > OATH to view your license details.

Provisioning

On the server side, secrets are provisioned by assigning a token to a user. An e-mail with configuration instructions is automatically sent to the user’s AXS Guard mailbox after a token has been assigned by an administrator.

On the client side, the user can simply import the secret by scanning the QR code provided in the e-mail, which also contains instructions to manually enter the required information.

Authentication Policies

New policies have been added to accommodate authentication with OATH tokens. These feature authentication methods for both password (PAP) and challenge (CHAP) based authentication protocols, as used by PPTP and L2TP VPN services.

Version 10.0

Kernel Upgrade

A new 64-bit kernel has been implemented. The previous kernel has also been upgraded to version 4.14. This is especially important when installing the appliance in a virtual environment; it will no longer be possible to boot your virtual AXS Guard appliance with a virtual machine that has been configured for a 32-bit guest OS.

The upgrade process may take over 30 minutes to complete. It is recommended to upgrade your appliance during off-peak hours or during a maintenance window to avoid service interruptions.

A new NAT option has been added to the Personal AXS Guard service to allow administrators to use the same subnet for multiple PAX units. Some minor changes were also made to the server-side user interface, making DHCP and passwords easier to configure.

A drag and drop feature has been implemented allowing administrators to easily change the order of rules in system policies, such as firewall policies.

A new reverse proxy back-end has been added to support Awingu version 4.0 and above.

Documentation

The AXS Guard documentation is constantly updated to reflect the various updates and improvements in the software and the product as a whole. Documents are available in PDF and HTML formats.

The following guides have been updated:

New Features

Kernel 4.14

Kernel updates introduce fixes which close up previously discovered security vulnerabilities and are the most important reason to upgrade your system.

Updates will also include support for new hardware, new functionalities and improve the stability and speed of your system.

IPsec netkey and VTI interfaces

The IP security (IPsec) stack is switched to the native linux implementation called netkey. In order to facilitate this transition, AXS Guard makes use of virtual tunnel interfaces (VTI), which provide routable ipsec software interfaces that support multicast, bandwidth management and load balancing, similar to the KLIPS IPsec stack used before.

The switch to netkey IPsec stack offers active development and support, a larger selection of cryptographic algorithm support, cryptographic offloading and parallel processing.

New PAX NAT Option

A new Translate Remote LAN option has been added, allowing administrators to reuse the same subnet for multiple PAX units.

Reverse Proxy support for Awingu 4.0

The reverse proxy has been refactored to support Awingu 4.0 and later versions. To configure the reverse proxy for use with Awingu 4.0, just select the "awingu-v2" back-end.
