Computer Network Security: Risks and Protective Measures

The spread of information networks in communities and organizations have led to a daily huge volume of information exchange between different networks which, of course, has resulted in new threats to the national organizations. It can be said that information security has become today one of the most challenging areas. In other words, defects and disadvantages of computer network security address irreparable damage for enterprises. Therefore, identification of security threats and ways of dealing with them is essential. But the question raised in this regard is that what are the strategies and policies to deal with security threats that must be taken to ensure the security of computer networks? In this context, the present study intends to do a review of the literature by using earlier researches and library approach, to provide security solutions in the face of threats to their computer networks. The results of this research can lead to more understanding of security threats and ways to deal with them and help to implement a secure information platform.

Computer and Network security Problem statement Unauthorized Access "As the threat of unauthorized access grows companies and people continue to look for security to upgrade." )``Unauthorized access'' is a very high-level term that can refer to a number of different sorts of attacks. The goal of these attacks is to access some resource that your machine should not provide the attacker. For example, a host might be a web server, and should provide anyone with requested web pages. However, that host should not provide command shell access without being sure that the person making such a request is someone who should get it, such as a local administrator.

Networks are vulnerable devices due to their basic feature of facilitating remote access and data communication. The information in the networks needs to be kept secured and safe in order to provide an effective communication and sharing device in the web of data. Due to challenges and threats of the data in networks, the network security is one of the most important considerations in information technology infrastructures. As a result, the security measures are considered in the network in order to decrease the probability of accessing the secured data by the hackers. The purpose of network security is to protect the network and its components from unauthorized access and abuse in order to provide a safe and secured communication device for the users. In the present research work a review in recent development of network threats and security measures is presented and future research works are also suggested. Different attacks to the networks and security measured against them are discussed in order to increase security in the web of data. So, new ideas in the network security systems can be presented by analyzing the published papers in order to move forward the research field.

Network security has become more important to personal computer users, organizations, and the military. With the advent of the internet, security became a major concern and the history of security allows a better understanding of the emergence of security technology. The internet structure itself allowed for many security threats to occur. The architecture of the internet, when modified can reduce the possible attacks that can be sent across the network. Knowing the attack methods, allows for the appropriate security to emerge. Many businesses secure themselves from the internet by means of firewalls and encryption mechanisms. The businesses create an “intranet” to remain connected to the internet but secured from possible threats. The entire field of network security is vast and in an evolutionary stage. The range of study encompasses a brief history dating back to internet’s beginnings and the current development in network security. In order to understand the research being perfo...

The development of information systems today is followed by an increase in attacks on information systems. This is due to the growing number of information systems that store sensitive data for users such as telephone numbers, population identification numbers, birth dates and even bank account numbers. These data are very prone to be misused by irresponsible parties. So security is one of the factors that must be the main consideration in the development of information systems. This research studies various attack techniques on information systems. To facilitate identification, these attacks are classified based on the components of the information system. The results of this study indicate that there are attacks aimed at each component of the information system. At the end of this study provides suggestions to minimize the impact of attacks and to improve information system security.

Network security refers to any activities designed to protect the network, which includes the authorization of information access in a network, which is controlled by the network administrator. Network security has turned out to be more important to personal computer users, Organizations, and military and it covers an assortment of computer networks, both public and private, that are utilized as a part of everyday jobs conducting transactions and communications among businesses, government agencies and individuals. Network security is the procedure by which digital information resources are protected, the objective of security are to ensure confidentiality, maintain integrity, and assure availability, so viable network security focuses on a variety of threats and prevents them from entering or spreading on the network. Social network sites created a new way of communication, it brought about new information security issues such as identity theft, privacy leak and junk information. In This paper we mainly concentrate on the network security also we present some major issues that can influence the network along with existing problems of the online security of the computer, and precautionary measures.

Network security has remained a major concern especially in the modern world where technological advancement is rapidly evolving. This study explores the concept of data and information security especially in today's environment where cyber risks like malware, phishing, DDoS, and insider threats are rampant. It covers the fundamentals of the network's security measures such as Firewall, IDS, Encryption, Access control, VPNs, and Security Auditing & Monitoring. A qualitative analysis of secondary data and case studies such as the Equifax data breach and the Yahoo data hack is used to assess the effectiveness of these security measures in the real world. Regulatory compliance is also encouraged through the use of standards like GDPR, PCI DSS, and HIPAA to ensure that companies meet the set requirements; failing to do so attracts fines, lawsuits, or loss of reputation among other consequences. Measures like regular software updates and patching, secure user authentication, network segmentation and security consciousness among the workers should be adopted. These are important in avoiding risk occurrences, minimizing threats and providing a hardy protection for new risks. This will be a detailed step by step guide to help organizations improve their network security, manage compliance and data protection in the interconnected world of today, with a focus on the importance of strong network protection in ensuring data integrity and trust.
