| − | ''The OWASP Internet of Things (IoT) Top 10 is a project designed to help manufacturers, developers, and consumers better understand the security issues associated with the Internet of Things, and to enable users in any context to make better security decisions when building, deploying, or assessing IoT technologies''.
| |
| − | | |
| − | The project defines the top ten security surface areas presented by IoT systems, and provides information on threat agents, attack vectors, vulnerabilities, and impacts associated with each. In addition, the project aims to provide practical security recommendations for builders, breakers, and users of IoT systems.

| |
| − | | '''I1: Insecure Web Interface'''
| |
| − | |
| |
| − | * Ensure that any web interface coding is written to prevent the use of weak passwords
| |
| − | * Ensure that any web interface coding is written to include an account lockout mechanism
| |
| − | * Ensure that any web interface coding has been tested for XSS, SQLi and CSRF vulnerabilities
| |
| − | * Ensure that any web interface has the ability to use HTTPS to protect transmitted information
| |
| − | * Ensure that any web interface coding is written to allow the owner to change the username and password
| |
| − | * Consider the use of web application firewalls to protect any web interfaces
| |
| − | |
| |
| − | When building a web interface consider implementing lessons learned from web application security. Employ a framework that utilizes security controls to ensure that vulnerabilities are mitigated in code. Be sure to plan for eventual upgrades or security fixes to the framework as well. If you use optional plugins to the framework be sure to review them for security.
| |
| − | | |
| − | Deploy and protect the web interface in the same way you would any web application. Utilize encrypted transport protocols if possible, being sure to validate certificates. Limit access in whatever ways possible. Assume users will not change configuration so deploy in a secure manner with strong credentials already in place.
| |
| − | |- style="vertical-align:top;"
| |
| − | | '''I2: Insufficient Authentication/Authorization'''
| |
| − | |
| |
| − | * Ensure that applications are written to require strong passwords where authentication is needed
| |
| − | * Ensure the application takes into account multi-user environments and includes functionality for role separation
| |
| − | * Implement two-factor authentication where possible
| |
| − | * Ensure password recovery mechanisms are written to function in a secure manner
| |
| − | * Ensure that applications are written to include the option to require strong passwords
| |
| − | * Ensure that applications are written to include the option to force password expiration after a specific period
| |
| − | * Ensure that applications are written to include the option to change the default username and password
| |
| − | |
| |
| − | Refer to the [https://www.owasp.org/index.php/Authentication_Cheat_Sheet OWASP Authentication Cheat Sheet]
| |
| − | |- style="vertical-align:top;"
| |
| − | | '''I3: Insecure Network Services'''
| |
| − | |
| |
| − | * Ensure applications that use network services don't respond poorly to buffer overflow, fuzzing or denial of service attacks
| |
| − | * Ensure applications test ports are taken out of service before going to production
| |
| − | |
| |
| − | Try to utilize tested, proven, networking stacks and interfaces that handle exceptions gracefully. Be sure that any test or maintenance interfaces are disabled or properly protected. Avoid exposing unauthenticated protocols (such as TFTP) or unencrypted channels (such as telnet) if possible. Consider the attack surface that device network services present. Turn off unnecessary services and deploy measures to protect required services, detect malicious activity, and react to an attack with measures such as lock-outs or temporary firewall rules.
| |
| − | |- style="vertical-align:top;"
| |
| − | | '''I4: Lack of Transport Encryption'''
| |
| − | |
| |
| − | * Ensure all applications are written to make use of encrypted communication between devices and between devices and the internet
| |
| − | * Use recommended and accepted encryption practices and avoid proprietary protocols
| |
| − | * Consider making a firewall option available for the application
| |
| − | |
| |
| − | Utilize encrypted protocols wherever possible to protect all data in transit. Where protocol encryption is not possible consider encrypting data before transfer.
| |
| − | |- style="vertical-align:top;"
| |
| − | | '''I5: Privacy Concerns'''
| |
| − | |
| |
| − | * Ensure only the minimal amount of personal information is collected from consumers
| |
| − | * Ensure all collected personal data is properly protected using encryption at rest and in transit
| |
| − | * Ensuring data is de-identified or anonymized
| |
| − | * Ensuring end-users are given a choice for data collected beyond what is needed for proper operation of the device
| |
| − | |
| |
| − | Data can present unintended privacy concerns when aggregated. As a rule collect the minimal amount of data possible. Consult with data scientists, legal and compliance teams to determine risk of data collection and storage. Consider implications of consent and the fact that IoT devices may not present an interface for collecting consent and may passively collect data about people other than owners and operators. IoT may collect information about individuals who cannot provide consent (such as minors) and data collection should be modified accordingly.

| |
| − | * Ensure all applications are written to produce alerts and notifications to the user for security events
| |
| − | |
| |
| − | Security can be a value proposition. Design should take into consideration a sliding scale of security requirements. Architect projects with secure defaults and allow consumers to select options to be enabled or disabled. IoT design should be forward compatible with respect to security - as cipher suites increase and new security technologies become widely available IoT design should be able to adopt these new technologies.
| |
| − | | |
| − | Remember the security lifecycle of protect, detect, and react. Design systems to allow for the detection of malicious activity as well as self defending capabilities and a reaction plan should a compromise be detected.

| |
| − | Many IoT deployments are either brownfield (i.e. applied over existing infrastructure) and/or have an extremely long deployment cycle. To maintain the security of devices over time it is critical to plan for patches and updates.
| |
| − | | |
| − | Confidentiality, Integrity, and Availability (CIA) are primary concerns when providing binaries and updates to edge devices. Encrypt updates before distribution, providing decryption keys along with download instructions to authorized devices. Updates should have cryptographic signatures using public key cryptography that can be verified by devices. A cryptographic signature allows for distribution of updates over untrusted channels, such as Content Delivery Network (CDN), peer-to-peer, or machine to machine (M2M).
| |
| − | | |
| − | Devices should always validate cryptographic certificates and discard updates that are not properly delivered or signed. If unencrypted updates are utilized be sure that a cryptographic hash of the update is provided over an encrypted channel so the device can detect tampering.
| |
| − | | |
| − | Provide a mechanism for issuing, updating and revoking cryptographic keys as well. Key management and lifecycle should be taken into consideration prior to deployment. This includes the SSL trust store, or root trust, on a device, which may have to be modified over the lifespan of the device.

| |
| − | * Consider writing applications to limit administrative capabilities to a local interface only
| |
| − | |
| |
| − | Plan on having IoT edge devices fall into malicious hands. Utilize whatever physical security protections are available. Disable any testing or debugging interfaces, utilize Hardware Security Modules (HSM's), cryptographic co-processors, and Trusted Platform Modules (TPM's) wherever possible.
| |
| − | | |
| − | Consider the implications of a compromised device. Do not share credentials, application or cryptographic keys across multiple devices to limit the scope of damage due to a physical compromise.
| |
| − | | |
| − | Plan for the transfer of ownership of devices and ensure that data is not transferable along with the ownership.

| − | ** Ensuring strong passwords are required by users
| |
| − | ** Implementing account lockout after 3 - 5 failed login attempts
| |
| − | * Recognize the value in autonomous IoT systems to perform security operations that are onerous or impossible to a user. Consider cryptographic authentication mechanisms, public key cryptography, and transitive trust schemes.
