One of the most significant challenges impacting these systems’ security is the outdated and insecure communication protocols that have been used for many years in various sectors. This work presents a practical solution to protect the SCADA’s critical communications’ confidentiality, authenticity, and integrity. This work put forward a hardware-based general-purpose cryptographic device based on FPGA technology. The device contains a handful of cryptographic algorithms that can be customized to harden the security of devices operating on the IEC 60870-5-101 communication protocol. The experimental results show that the proposed solution enhances the secrecy and integrity of the IEC 60870-5-101 messages and ensures the source’s authenticity.

Most of the developed countries implement telemedicine services to allow both patients and medical doctors to access medical data and medical services quickly and efficiently. However, as the data and services are made accessible online, the data security becomes the concern. Without proper security mechanism in place, the vulnerabilities of telemedicine systems can be exploited which will give negative impact to the patients and medical services as a whole such as wrong treatment being given and confidential data leakage. This paper analyze the security issues in telemedicine as an IOT system and identify related security countermeasures from related works to manage the security issues in telemedicine.

However, most of them are designed for images distorted by compression, noise and blurring. There are very few IQAs designed specifically for CDI, e.g. Contrast distortion may be caused by poor lighting condition and poor-quality image acquisition device. No Reference-Image Quality Assessment (NR-IQA) for Contrast-Distorted Images (NR-IQA-CDI) is one of these few IQAs. The five features used in NR-IQA-CDI are the global spatial statistics of an image including the mean, standard deviation, entropy, kurtosis and skewness. Unfortunately, the performance of NR-IQA-CDI are not encouraging in two of the three test image databases, TID2013 and CSIQ, where the Pearson Linear Correlation Coefficients are only around 0.57 and 0.76, respectively. Therefore, this paper presents the reason which led to poor results in existing NR-IQA-CDI. This paper also can address the problem of existing NR-IQA-CDI which the weakness of the global features in assessing images with uneven contrast.

The wide range of supported applications has made this life-saving management system the key element of every industrial control infrastructure in various sectors. The complexity and sophistication of SCADA systems have been increased dramatically over the last few years. Various cyberattacks have targeted these systems by exploiting zero-day vulnerabilities or targeting a nearby Internet-enabled appliance or computer system. To this end, many efforts have been proposed previously to model the threats on SCADA systems to eliminate potential danger and diminish the catastrophic consequences in the physical domain. The main contribution of this work is to present a multi-facets threat assessment model to aid security teams to systematically perform various cybersecurity analysis practices such as penetration testing, vulnerability assessment and risk analysis.
