Background Certain vulnerabilities may depend on the processor architecture that a device is using. Motivation for false-positives Axis edge devices such as cameras, encoders, wearables, audio and intercom products are based on MIPS and ARM architecture and are, e. Background Security scanners highlight when a device is running an outdated version of a software component.

It may even occur that the security scanner is unable to determine what version is actually running, so flags it anyway. The security scanner simply compares the version of those software components running on the Axis device against the latest available version. The security scanner then outputs a list with security vulnerabilities, even without confirmation that the device under test is really affected as such.

Motivation for false-positives Open source software components do receive new features, bug fixes and security patches throughout the course of their development, resulting in a high release cycle. Therefore, it is not uncommon that the Axis device under test is not running the latest version of a software component. However, Axis is monitoring open source software components for security vulnerabilities that could potentially be deemed critical by Axis and will publish those accordingly in a security advisory.

This may result in vulnerabilities not being detected by security scanners since the package version is not easily identifiable. Axis strongly recommends to keep the device firmware up-to-date and encourages to perform security audits on your devices. Motivation for false-positives Axis devices do encrypt user secrets such as passwords, certificates, keys and other files without necessarily encrypting the filesystem.

The firmware does not contain any secrets by default and needs no other protection than the firmware signature to validate the integrity. Encrypted software makes it harder for security researchers to identify new unknown vulnerabilities and encrypted software may be used by vendors to hide deliberate flaws security through obscurity. For Axis devices, root access is required to access the filesystem of the device to gain access to it.

Sensitive information such as passwords are stored encrypted on the filesystem and require a high level of sophistication, skillset, time and determination to extract. Make sure to use a strong root password and keep it protected. Background Security scanners may believe that they have identified the make and model of the bootloader implementation Axis is using in their products and therefore highlight vulnerabilities with regards to secure boot or the bootloader itself.

Axis refers to this as debug port. Motivation for false-positives The debug port is used only for development and debugging purposes during engineering projects. While no sensitive information is exposed while being unauthenticated, the access to the debug port is password restricted and only the root user may login.

At all times, it is recommend to configure a remote syslog server where the Axis device can send its syslogs. This will ensure that the logs can be kept and reviewed for a suitable time and not get erased after e. No authentication will be performed if an unsuited source IP-address is trying to access the Axis device since the network transmission is blocked right at the layer-2 network while authentication is performed on higher level application layers.

For a certain amount of time, a defined number of authentication fails. This feature can help in avoiding and protect the Axis device against brute-force attacks, or from network clients that unintentionally imitate a similar behavior. Below you'll find two use cases and configuration examples followed by an explanation of each parameter used. Trying to access the web interface from the network client that was previously identified as a threat would result in a HTTP Forbidden response. Furthermore, the Axis device would log the following internally in the system log: T Configuration example 1 After three login attempts within 30 seconds, the client IP address gets blocked for 10 seconds.

Every following failed request within the 30 seconds page interval will result in the DoS Blocking Period being extended by another 10 seconds. Configuration example 2 After two login attempts within 10 seconds, the client IP address gets blocked for 10 seconds.

Every following failed request within the 10 seconds page interval will result in the DoS Blocking Period being extended by another 10 seconds. DOSBlockingPeriod : The blocking period is the amount of time in seconds a client will be blocked if they are added to the blocking list.

During this time, all subsequent requests from the client will result in a Forbidden , and the timer being reset e. Since the timer is reset for every subsequent request, it is not necessary to have a long blocking period; in the event of a DoS attack, this timer will keep resetting. Once the threshold for that interval has been exceeded, the IP address of the client will be added to the blocking list.

DOSSiteCount : This is the threshold for the total number of requests for any object by the same client on the same listener per site interval. About signed firmware Signed AXIS OS firmware is a feature that was introduced to ensure that only verified and trusted firmware is uploaded and used in Axis devices.

In this section you can read about technical details that will ensure that the correct update and downgrade paths are chosen to avoid issues. For more general information, see the white paper about signed firmware, secure boot and security of private keys. This means it is not possible to perform a firmware rollback or downgrade below AXIS 8. Answer: Yes, this will work. Answer: The downgrade will fail. The unsigned firmware will be rejected by the device and it will continue to run AXIS 9.

So first from 9. Please note that Axis does not encourage downgrades to older, unsupported firmware in general. Troubleshooting How to identify that a firmware upgrade did not work because of an unsigned firmware? In case a user tries to upload an unsigned firmware, one of the following messages is displayed in the log files of the camera when a firmware upgrade fails due to signed firmware. Axis devices support a variety of ways to access the device over the network for initial configuration, maintenance and management purposes in order to ensure proper identity and access management and safeguarding over Axis devices.

Legacy access procedure default user with default password Historically, Axis devices shipped from production and in their factory defaulted state have had their VAPIX and ONVIF interfaces activated for quick and easy out-of-the-box access on the network for clients connecting to them. Furthermore, the new access procedure has been rolled out in new firmwares on individual product releases that are located outside of the above major platform releases, such as:.

I forgot my password, what to do? There is no possibility to recover lost or forgotten access credentials to an Axis device. The Axis device needs to be reset to its factory default settings in order to reconfigure it with new access credentials. Please remember to verify the download against the provided sha hash before using Axis device ID Root CA as a trust anchor. Telnet Telnet is supported by Axis devices with firmware version 5.

Follow the instructions below in order to use Telnet on the device:. CER and. PFX and. Self-signed certificate Axis devices come with a preinstalled self-signed certificate in order to provide the possibility to access the device via encrypted HTTPS connection and proceed with the initial setup of the device. Security scanners might highlight the existence of any self-signed certificate that is uploaded on the device as insecure e.

Axis recommends removing the self-signed certificate from the device and replace it with a server certificate that is trusted in your organization when HTTPS connection is the preferred type of connection to the device.

This means that CA certificates that are going to be uploaded in the CA certificate section of the Axis device need to fulfil one of the following:. The keyUsage attribute extension with bit keyCertSign set but without basicConstraints. If all information is correct, the certificate upload will end successfully. However, if system changes occur between the time the CSR was issued and the certificate was uploaded, the process can be interrupted.

Possible reasons why a certificate upload would fail are:. Axis offers product firmware management according to the active track or the long-term support LTS tracks. Regardless of the track chosen, it is recommended to upgrade the firmware regularly in order to get the latest security updates.

The entire cluster should always be on the same firmware. Right click and select Upgrade Firmware , which will open a dialog with a list of device models and the current firmware version installed in each device.

Browse to locate firmware file e. Select Check for Updates to download a list of all firmware available for all device models. Select browse to locate firmware files and import them. It is possible to select and import several files at the same time. Each device model will show a dropdown containing all available firmware for a model. By default, firmware upgrade is done for all the selected devices at the same time.

Once a firmware update has been started, the devices will be unavailable until the installation and restart of the devices has completed successfully. The procedure to update firmware differs slightly depending on the version of the installed web interface before and after 7.

Open the product's start page e. Click the Setup link and log in as "root" or any other user with administrator privileges. You must be logged in as an administrator to upgrade the unit. Click the Browse button in the Upgrade Server section. Select the upgrade file you downloaded and maybe decompressed from our site. This file is typically named after the product and firmware version.

Click the Upgrade button in the Upgrade Server section. Wait for the flash load to complete, which may take minutes. The upgrade procedure occurs in four steps:. Step 2: Uploading firmware. The old firmware will be erased and the new firmware will be saved.

After a while the progress of the upgrade will be displayed in the web browser. Step 4: Reconfiguration. The new firmware settings are configured to match the previous settings. The color of the status LED will be amber during this step. After the upgrade has completed, the unit will automatically initiate the system, during which the status LED blinks amber. When initiation is complete and the system is ready for use, the status LED will be green.

From the command prompt, open an FTP connection to the unit you wish to upgrade. Type the command "put XXX. After a while, the progress of the upgrade will be displayed in the command prompt. When initiation is complete and the system is ready for use, the color of the status LED will be green. Downgrading the firmware of an Axis product might be necessary in order to establish compatibility to 3rd party systems which do not support later Axis firmware versions. The downgrade is performed in the same way as an upgrade.

Instructions are available in How to upgrade. It is only recommended to downgrade the firmware of an Axis product using the standard upgrade process if performed in combination with a factory default of the product.

The factory default can be performed simultaneously during the downgrade, or manually by the user afterwards. As of firmware version Known limitations Support for a new type of NAND flash memory was added to a number of products in service releases 6. Products receiving the new type of memory also received a new hardware id HWID. The new flash memory will not allow a firmware downgrade, meaning that products with the new HWID cannot downgrade to a firmware prior to the service release.

See list of affected products below. When upgrading the firmware in an Axis product, a restore point of the previous state of the product and its entire configuration is made before the upgrade. This restore point is available to go back to after the firmware upgrade has been performed in case of an unexpected issue. This feature is called firmware rollback.

A video clip with instructions can also be found in Configuration tips. The feature was introduced in firmware version 7. It is recommended to use the firmware rollback function to re-establish system functionality and to contact Axis Technical Support for further instructions and troubleshooting techniques. No restore point is available when the product is in a factory defaulted state.

The purpose of this section is to encourage and enable partners, system integrators and end users to consider their individual setup when configuring general video streaming settings in Axis devices in order to ensure optimal performance and user experience. General considerations Axis video capable devices deliver a video stream according to the desired requirements of the system it is used in and according to the specifications of the Axis device itself.

The following information provides a foundation and understanding of how video streaming in Axis devices works and what settings to consider. About video streaming clients The Axis device as such recognizes several types of clients that it encodes and distributes video streams to. The clients can be categorized as internal and external , and they are served with video streams as they are requested.

See examples below for each category:. The number of unique encoded streams tells us how many different video streams an Axis device is encoding. This information can be obtained in the server report of devices with firmware version 5. The number of unique encoded streams are affected by stream properties, as will be shown in the examples below.

Note that the illustrations are taken from a graphical user interface to better illustrate the usecase. Example 1 : In this example, the Axis device is encoding a total number of three unique encoded video streams. The video streams differ in one stream property - resolution - and since the resolution is different, the Axis device needs to encode each video stream separately. Example 2 : In this example, the Axis device is encoding a total number of two unique encoded video streams.

The video streams differ in one stream property - frame rate fps - and since the frame rate is different, the Axis device needs to encode each video stream separately. Conclusion : Axis devices need to encode video streams according to their stream properties.

This may have an impact on video streaming performance and generally it is recommended to optimize the setup towards the least amount of video streams possible.

If more physical network clients need to pull the same video stream, we suggest implementing multicast video streaming instead, or to have additional clients request another unique encoded video stream. The number of distributed video streams refers to the number of actual physical network clients in the network and the number of video streams that they are requesting. For example, it would be possible to video stream from AXIS Camera Station and from the web interface of the Axis device from the same physical network client.

This information can be obtained in the server report of devices with firmware version 9. This section lists the number of distributed streams in relation to their destination IP address. The distributed stream is declared as a ratio of Number of video streams:Number of physical network clients.

Example 1 : In this example, the number of distributed streams is because the Axis device streams in total two video streams to two physical network clients.

Example 2 : In this example, the number of distributed streams is because the Axis device streams in total three video streams to two physical network clients. Observe that the Physical network client 1 is requesting the Unique encoded stream 1 twice. Conclusion : An Axis device can stream a single or many video streams to either the same or many physical network clients.

A physical network client is defined by the number of video streams it is requesting and its destination IP address in the network. With the information above, we can now explain the relation between the number of unique encoded streams in relation to the number of distributed streams to physical network clients. Example 1 : In this example, two physical network clients are requesting a unique encoded stream each. This results in a distributed stream to each physical network client.

Example 2 : In this example, the Axis device is encoding two unique streams and distributes them to three physical network clients. Example 3 : In this example, the Axis device is encoding a single unique stream and distributes it to two physical network clients via multicast. Observe that this setup would result in a single distributed stream only as the two physical network clients will receive the stream from the multicast address.

So, multicast has the advantage of consuming less network bandwidth compared to example 4 below. Example 4 : In this example, the Axis device is encoding a single unique stream and distributes it to two physical network clients via unicast instead. Compared to example 3, this setup would require the Axis device to consume more network bandwidth as the unique stream has to be distributed twice.

The number is set to 10 or 20 in all Axis devices and is depending on the configuration and performance capabilities of the device. This means that either the Axis device is delivering a single video stream to 10 or 20 different physical clients in the network, or the Axis device is delivering 10 or 20 different video streams to one client in the network. The number of receiving video clients physical and software instances is the main limit.

In practice, the maximum number should never be reached at any point. If an increasing number of clients need to access the video stream, it is recommended to make use of e. In Maximum number of clients , we learned that there is a limit to how many video streams a device can deliver as a maximum, and we explained this with the number of video streams. In addition to video streams, Axis devices can also deliver audio and metadata streams.

While the purpose of video and audio streams is self-explanatory, the purpose of metadata might not be. Below is an example of an Axis device that is currently streaming one of each stream type to a single physical network client. Observe which stream type is streamed under Media.

To summarize, the maximum number of clients is applied to video, audio and metadata streams separately, meaning that if the parameter MaxViewers is configured to 20, the Axis device can deliver 20 x video, 20 x audio and 20 x metadata streams in total. In the example illustration below, one can observe that the Axis device can deliver five unique video streams in full frame rate of 30 fps. In case a sixth unique video stream needs to be encoded, the performance of the product will be exceeded, causing the Axis device to deliver all of the requested video streams equally in reduced frame rate.

In case of exceeding the performance of the product, the Axis device will not prioritize any of the video streams to be delivered in full fps, instead it will distribute the performance bottleneck across all video streams. In case a sixth unique video stream needs to be encoded, the performance of the product will be exceeded, causing the Axis device to deliver all of the video streams in reduced frame rate.

Please note that the above example is an oversimplified illustration and the number of concurrent video streams an Axis device can deliver in full frame rate is heavily dependent on a lot of factors, such as requested frame rate, resolution, compression, bitrate and many more. It is recommended to test the device against the desired behavior in an environment that is exact, or close to, the environment the device is installed in.

Maximum video stream bitrate A typical H. In addition to the above information, the below listed Axis devices have additional video buffer configurations that must be considered. These devices have in total four statically configured so called video source buffers.

For single-sensor products, the video source buffer can deliver at least one unique video stream, and for multi-sensor products, the video source buffer can deliver at least 4 unique video streams. So, Axis devices containing video source buffer configurations are limited by the amount of unique video streams they can provide.

This buffer provides variations of possible resolutions. So, in summary, this device can deliver 2 x unique video streams in max x resolution — one in max x and one in x Example 1 : In this example, the Axis device is delivering the following unique video streams which means the Main, 3rd and 4th video source buffers are in use.

Requesting e. Example 2 : In this example, the Axis device is delivering the following unique video streams which means the Main and 3rd video source buffer are in use. Requesting a unique video stream buffer in x resolution can however be delivered by the 4th source buffer. Axis device specifics Below are all Axis devices and their video source buffer configurations listed:. Example: either 4xp in total with 2xp delivered from the main source buffer and 2xp delivered from the 4th source buffer, or 2x4k delivered from the main source buffer and 2xp delivered from the 4th source buffer.

Example: 1 x video stream in x resolution per sensor on AXIS QE makes it a total of 4 video streams on the main source buffer. Troubleshooting You may refer to each device's release notes for all the supported resolutions. A typical first hand indication that the Axis device cannot provide additional unique video streams as the video source buffers are already exceeded is the " Service Unavailable" error message in the web interface of the Axis device.

The Server Report and included log messages of Axis devices are an excellent tool to debug this kind of scenarios. Below you can find a list of some common log messages that would appear in case the video source buffer is saturated and the Axis device is not being able to deliver a requested unique video stream. Troubleshooting example 1 : In this example, requesting a unique video stream has failed due to there simply not being any video source buffer available to facilitate another unique x video stream.

The log messages indicate which source buffer is already occupied and which is still available to use at the time when the new unique video stream is requested. Troubleshooting example 2 : Like in the example above, requesting a unique video stream has failed due to there not being any video source buffer available to facilitate another unique x video stream.

Troubleshooting example 3 : Axis devices with newer firmware print their log message in a slightly different manner, as seen in this example. Recommendations The following general recommendations can be given to reduce complexity, configuration time and to optimize the video streaming setup of Axis devices:.

Make use of stream profiles to package streams and their configuration in a simple way to optimize stream and configuration handling. Have in mind that action rules allocate a video source buffer once the action rule is activated. This means that even though the Axis device is supposed to send an image to an FTP server once a day, it will result in the video source buffer being allocated for the entire day.

This might consume a video source buffer by itself. Avoid having anonymous viewers enabled. Besides the aspect of cybersecurity, having anonymous viewers enabled allows the uncontrolled access to an Axis device and may exceed the video source buffer configurations. Avoid questionable setups such as requesting two unique video streams in the same resolution, framerate but with different compression, like 30 and The difference in image quality is negligible compared to the cost of consuming a video source buffer.

Streaming video using multicast allows different video clients located in the network to access a single video stream which the Axis device distributes to a specific multicast address and port. One of the benefits of using multicast as a transport method for video streaming is that the Axis device keeps its system and resource consumption low by only sending a single or dual video stream to a specific address in the network.

It is also an efficient way of using the network infrastructure since many different video clients can retrieve the video stream from the multicast address instead of each video client pulling a separate video stream from the Axis device. The way multicast is served, distributed and received in the network can actually minimize the bandwidth consumption of the network infrastructure and all its involved clients as such.

Just imagine the difference this can make in a system with more than 5. Axis devices support a variety of ways to stream video in a multicast scenario. In the following sections we will go through multicast from a streaming perspective and not take into account the general mechanics of multicast and how it is routed through the network, or the basics of the different forms of multicast.

Independently of the desired transport method — i. We will go through the details of a typical RTSP build-up step-by-step below. For more details, please refer to the actual network traces in Multicast in detail for more research. Step 2: Axis device The Axis device validates the request and shares the corresponding SDP file with the video client. Note that in any-source multicast mode, no multicast-specific network parameters are shared.

In source-specific multicast mode SSM , this is different. Step 3: video client The video client then goes ahead and defines the appropriate transport method as multicast, the multicast IP address, streaming ports and the TTL. This is the important step in the RTSP build-up where the video client actually can specify the desired transport method.

Step 4: Axis device The Axis device in return validates the request and if successful, it answers with the exact same network parameters back to the video client to prepare the upcoming session. Step 5: video client The video client then finally signals to the Axis device via RTSP PLAY to start video streaming as agreed based on the network and video streaming parameters that have been handshaked previously. Step 6: Axis device The Axis device acknowledges the request by sending an RTSP OK and provides the video client with info on how the video stream will be momentarily available at the defined multicast network parameters.

In order to signal the start of the video stream to the video client, the Axis device specifies the sequence number of the first RTP package and the initial rtp timestamp so that the client expects and processes the correct start of the video stream. The Axis device treats this as a non-complete request and offers instead its configuration set in R0, which the video client either can agree on or simply close the connection.

In SSM, the multicast network parameters are pre-configured in the Axis device and shared with the requesting video client when the SDP file is shared. The benefit of this is that the requesting video client can join a multicast group and only filter for the multicast traffic the video client is interested in.

This can be done by applying a source-specific filter when joining the multicast group. A typical scenario where SSM would be beneficial is when multiple Axis devices would stream video to the same multicast address but would use different ports. A video client connecting via any-source multicast would receive the multicast traffic from all streaming devices, while a video client requesting source-specific multicast would be able to filter out unwanted traffic. Source-specific multicast requires pre-configuration on the Axis device to configure the desired multicast network parameters.

You can find information on how to configure an Axis device for source-specific multicast in the VAPIX Library but is also illustrated below. Below is a typical example configuration:. Step 1: video client Compared to the any-source multicast mode, SSM mode requires a different streaming URL for signaling to the Axis device that source-specific multicast is wanted.

Step 2: Axis device The SDP file that is shared between the Axis device and the requesting video client includes the source-specific multicast network parameters which the video client has to learn in order to join the multicast group accordingly and filter for the correct traffic.
