Each online based server cannot be fully secured from various external attacks that attempt to infiltrate the system. Server security is the most important part for administrators against intruders who carry out their actions in attacking computer systems, there are several attack methods that can be done, method like brute-force are usually deployed to attack computer security systems that are connected to the internet. In this study to overcome attacks penetrating into the server system, the port knoking method can be used as a step taken to prevent attacks that enter the system or also known as the authentication method. By using this port knoking method the administrator can control the system to be more secure from brute-force attackers addressed in certain parts such as SSH server and FTP server. So that users can perform services connected with SSH server and FTP server services, knocked functions as a port knocking daemon that is ready to receive port knocking authentication from the user then rewrites the firewall, so that the connected services can be secured from attacks that try to infiltrate the server system. Furthermore, Ip tables and uncomplicated firewalls function to build firewalls that will deny connections to the SSH server and FTP server services. So when a foreign user accesses SSH and FPT without first doing the autendiction, the firewall will reject the connection, but if the user passes the port knocking autendiction stage via sending SYN packets to the port provided in the knocking daemon port, then the knocking daemon port is will rewrite the firewall so users can connect to the SSH server and FPT server services.

Security is a million dollar issue for all computer systems. Every week there is news of another major breakin to a commercial or government system. Also it is well known that many governments are actively engaged in cyber-warfare, trying to break into the systems of other governments and other groups. The Internet of Things is increasingly changing into an omnipresent computing service, requiring vast volumes of knowledge storage and process. Unfortunately, due to the unique characteristics of resource constraints, self-organization and short range communication in IoT, it always resorts to the cloud for outsourced storage and computation. Security is one of the major challenges faced by cloud based IoT. The standard file protection technique relies on password based encryption schemes and they are vulnerable to brute force attacks. The reason is that, for a wrongly guessed key, the decryption process yields an invalid-looking plaintext message, confirming the invalidity of the key, while for the correct key it outputs a valid-looking plaintext message, confirming the correctness of the guessed key. Honey encryption helps to minimise this vulnerability. Hence, this paper proposed an extended Honey Encryption (XHE) scheme for enhancing the security of the cloud based IoT.

The proper functioning of a hospital computer system is an arduous work for managers and staff. However, inconsistent policies are frequent and can produce enormous problems, such as stolen information, frequent failures, and loss of the entire or part of the hospital data. This paper presents a new method named EMRlog for computer security systems in hospitals. EMRlog is focused on two kinds of security policies: directive and implemented policies. Security policies are applied to computer systems that handle huge amounts of information such as databases, applications, and medical records. Firstly, a syntactic verification step is applied by using predicate logic. Then data mining techniques are used to detect which security policies have really been implemented by the computer systems staff. Subsequently, consistency is verified in both kinds of policies; in addition these subsets are contrasted and validated. This is performed by an automatic theorem prover. Thus, many kinds of vulnerabilities can be removed for achieving a safer computer system.

The purpose of this study was to determine whether people with visual impairment in Japan are provided with useful information by their ophthalmologist while being notified of their disability, and what information is needed by these individuals upon being diagnosed. An analysis of the responses from 197 respondents revealed that only 30.45% had been provided information by their ophthalmologist upon being diagnosed, while 69.55% patients were not provided any information. When asked about the form of media they used to receive information, the most frequently used was the internet (16.68%). As web accessibility is not sufficient in Japan, making information media accessible to the visually impaired is a challenge. Finally, when asked about the type of information they would like to be provided, the most common answer was information about peer support. This suggests that ophthalmologists are expected to (1) understand the needs of the visually impaired and (2) provide information appropriately and promptly.

Positive Effect

<p><em>The purpose of this study was to determine the effect of donations, restricted funds, organizational size, and age of the organization age on the voluntary disclosure of the foundation. All foundations in Indonesia are the population in this study. The sample of this research is foundations in Indonesia that submit financial reports via the internet between 2013-2019 and have complete data. Based on these criteria, 114 financial reports were obtained as the research sample. The results of this study prove that restricted funds and organizational size have a significant positive effect on voluntary disclosure, while the donations and age of the organization have no significant positive effect on voluntary disclosure. The implication of this research is that funders must consider the restricted funds and the size of the organization to assess the prospects of the foundation. In addition, the foundation must increase voluntary disclosure to be more transparent in providing information about its foundation. With transparency, the foundation will more easily get the trust to receive funds that are beneficial to the foundation's survival.</em></p>

Security is always at the forefront of developing technologies. One can seldom go a week without hearing of a new data breach or hacking attempt from various groups around the world, often taking advantage of a simple flaw in a system’s architecture. The Internet of Things (IoT) is one of these developing technologies which may be at risk of such attacks. IoT devices are becoming more and more prevalent in everyday life. From keeping track of an individual’s health, to suggesting meals from items available in an individual’s fridge, these technologies are taking a much larger role in the personal lives of their users. With this in mind, how is security being considered in the development of these technologies? Are these devices that monitor individual’s personal lives just additional vectors for potential data theft? Throughout this survey, various approaches to the development of security systems concerning IoT devices in the home will be discussed, compared, and contrasted in the hope of providing an ideal solution to the problems this technology may produce.
