Data that is no longer required should be disposed of securely, and if data is stored, maintaining compliance with legal and regulatory frameworks is also an important challenge.
Adopting an IoT Platform that provides security by default helps to resolve these issues, for example by enabling two factor authentication 2FA and enforcing the use of strong passwords or certificates.
For example, in connected citiesIoT infrastructure is responsible for essential services such as traffic control, and in healthcare, IoT devices include pacemakers and insulin pumps. Implementing data privacy includes redacting or anonymizing sensitive data before it is stored or using data separation to decouple personally identifiable information from IoT data payloads.
Incorporating security by default — where security features are configured at their most secure settings at all times, including before, during, and after development enables you to maintain data privacy and integrity, while delivering highly available IoT data, apps, and services. Just like devices, apps should also support secure authentication, both for the apps themselves and the users of the applications, by providing options such as 2FA and secure password recovery options.
When developing IoT applications, be sure to apply secure engineering practices to avoid vulnerabilities such as the OWASP top 10 vulnerabilities. Predict and preempt security issues 1 — Secure constrained devices Many IoT devices have limited amounts of storage, memory, and processing capability and they often need to be able to operate on lower power, for example, when running on batteries.
However, there are many IoT devices that fall down when it comes to device authentication, for example, by using weak basic password authentication, or using passwords unchanged from their default values.
Security approaches that rely heavily on encryption are not a good fit for these constrained devices, because they are not capable of performing complex encryption and decryption quickly enough to be able to transmit data securely in real-time.
Blockchain — as a decentralized distributed ledger for IoT data — offers a scalable and resilient approach for ensuring the integrity of IoT data.
Strategies for detecting vulnerabilities and breaches include monitoring network communications and activity logs for anomalies, engaging in penetration testing and ethical hacking to expose vulnerabilities, and applying security intelligence and analytics to identify and notify when incidents occur.
Conclusion Adopting a multi-layered security-by-design approach to IoT development is essential for securely managing devices, data, and mobile and cloud-based IoT apps and services, as well as dealing with threats or issues as they arise.
In large scale IoT systems, the complexity of the system in terms of the number of devices connected, and the variety of devices, apps, services, and communication protocols involved, can make it difficult to identify when Security challenges incident has occurred.
In some applications, the impact of the lack of availability could mean loss of revenue, damage to equipment, or even loss of life. Not all devices support over-the-air updates, or updates without downtime, so devices might need to be physically accessed or temporarily pulled from production to apply updates.
For example, you need to keep track of which updates are available apply updates consistently across distributed environments with heterogeneous devices that communicate through a range of different networking protocols. This feature is particularly important for key devices such as gateway devices in order to limit their potential to cause harm or disruption, for example, by flooding the system with fake data if they have been compromised.
IoT systems should make use of multiple layers of defense, for example, segregating devices onto separate networks and using firewalls, to compensate for these device limitations. To ensure high availability, IoT devices must be protected against cyber-attacks as well as physical tampering.
Challenges include identifying which devices were affected, what data or services were accessed or compromised and which users were impacted, and then taking actions to resolve the situation.
How do you know if your IoT system has been compromised? Instead, constrained devices typically only employ fast, lightweight encryption algorithms.

The potential for disruption as a result of connectivity outages or device failures, or arising as a result of attacks like denial of service attacksis more than just inconvenience.Security and privacy are critical issues facing the development of the internet of things.
These 4 challenges are key to making IoT safer. Here is a list of what I believe are the top ten national security challenges the United States will face in (in no particular order): 1. Helping the Middle East Secure its own Future. While the rise of e-commerce and cloud data storage have proven to be a boon for consumers, a host of cyber security challenges have emerged for retailers.
