The digital boom brought empowerment to seamless connectivity by enabling manufacturers to harness the power of the Internet into their products, opening up the world of the Internet of Things (IoT). However, such connectivity has also brought the side effect of such power being abused by unscrupulous agents, who scan open ports for services and exploit vulnerabilities in the system. The Mirai botnet malware attack is one such example that caused havoc by compromising millions of IoT devices having unpatched/weaker security. There is an increasing need to enable IoT devices to be fully patched and secured, but such methods are often under attack. This paper examines a stealth technology and its impact on the CPU and power consumption to secure resource-constraint IoT devices that are growing exponentially. By enabling secure remote operations and management of such devices using a unique but practical method of security called "Port Knocking," we can ensure timely patching of security vulnerabilities in a safe and stealthy manner. Our experimental results on a resource-constraint IoT device show that port knocking not only secures the device and provides a secure remote management option but also helps in keeping its power consumption low. The results obtained make it an effective security layer for securing resource-constraint IoT devices.

Existing research on information security for IP cameras has been primarily focused on issues with authentication or malware, but not on the peeping method itself. How cyber peeping is conducted in real world can further help in strengthening defenses accordingly and spread more awareness about dangers of IP camera. In this research, we observed peeps by setting up a honeypot using decoy cameras in two scenarios. First, where background information (handwritten URL and ID/password bait) can be read by humans. Second, simulating a living-room in a home environment. As a result, many examples of peeping into the decoy cameras were confirmed in reality. Also, a rapid increase in peeping (over 20,000 times/day) was seen after a decoy camera's feed got posted on a well-known website, showing a large scale peeping danger also exists due to such websites. The results of this study were used in several TV programs to show the dangers of using IP cameras over a national broadcasting station and also were directly shared with IP camera vendors, resulting in the improvement of IP camera security. Therefore, we believe that this study can further help in improving the security and awareness on the dangers associated with IP cameras.

Attempts to facilitate and streamline systems architecting have resulted in a great number of reusable principles, practices, mechanisms, frameworks, and tools. Such a practice is the use of architectural viewpoints and views. However, as systems change, these practices should also evolve. The increasing scale and complexity of systems resulting from an ever-growing pool of human needs and breakthroughs may lead, in some cases, to an increased gap between the abstraction activities attempting to capture the whole of a system, and the instantiation activities that produce concrete and detailed descriptions of a system’s architecture. To address this issue, this article introduces a new notion, that of architectural glimpse statements, fundamental questions acting as the building blocks for architectural views and products. This notion can help architects ask the right questions in the right manner to create fundamental statements, the elaboration on which can lead directly to concrete architectural products. Working on top of standardized and common approaches, the article introduces a language for the creation of architectural glimpse statements using the 5W1H maxim. Based on this language, a tool and guidelines are also provided to facilitate the usage of glimpses. Finally, the overall methodology is demonstrated in two case studies.
