IoT security has been a critical focus for the past decade, particularly highlighted by incidents like the 2016 Dyn DDoS attack, which exploited vulnerabilities in unsecured IoT devices to create a botnet that disrupted major online services. This attack emphasized the importance of improving IoT security standards, as many devices were compromised due to unchanged default passwords. In response, companies recognized the need for secondary DNS providers and the necessity of changing default passwords, although the latter remains largely within the user's control. PubNub, a data streaming network, has been proactive in addressing IoT security with features like transport layer security (TLS) and AES encryption, enabling secure communication and compliance with regulations such as HIPAA and GDPR. Despite increased competition, PubNub's commitment to security and innovation positions it as a leader in enhancing IoT technology, encouraging further industry advancements by providing reliable and secure solutions.
