Computer and Network Security

As the internet evolves and computer networks become bigger and bigger, network security has become one of the most important factors for IT industry to consider. Network Security is a key to successful communication among personal computers, organizational computers or any other systems that are connected via network. Its entire field is vast and in an evolutionary stage. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs, conducting transactions and communications among businesses, government agencies and individuals [1]. Network security is typically handled by a network administrator or system administrator who implements the security policy, network software and hardware needed to protect a network and the resources accessed through the network from unauthorized access and also ensure that employees have adequate access to the network and resources to work. This paper briefly addresses the concept of Network Security, Threats of Network Security and the Measures that can be taken or may be useful for the efficient and reliable flow of data among the various systems, connected via network [3].

By writing this paper a small effort has been put to understand the growing network needs and its security. Various types of network threats and security services are discussed. This will help in designing a secure and robust network infrastructure by discussing management security policies and risk analysis.

The first question to address is what we mean by "network security." Several possible fields of endeavour come to mind within this broad topic, and each is worthy of a lengthy article. To begin, virtually all the security policy issues raised in Matt Bishop's book, Computer Security Art and Science,1 apply to network as well as general computer security considerations. In fact, viewed from this perspective, network security is a subset of computer security. The art and science of cryptography and its role in providing confidentiality, integrity, and authentication represents another distinct focus even though it's an integral feature of network security policy. Readers looking for a good introduction (and more) to this area should consider Practical Cryptography by Niels Ferguson and Bruce Schneier. The topic also includes design and configuration issues for both network-perimeter and computer system security. References in this area include Stephen Northcutt and colleagues' Inside Network Perimeter Security,3 the classic Firewalls and Network Security4 by Steven Bellovin and William Cheswick, and too many specific system configuration texts to list. These are merely starting points for the interested novice. The practical networking aspects of security include computer intrusion detection, traffic analysis, and network monitoring. This article focuses on these aspects because they principally entail a networking perspective.

Concepts, Methodologies, Tools and Applications

Network security is defined as "a set of procedures, practices and technologies for protecting network servers, network users and their surrounding organizations" (Oppliger, 2000, Preface). The need for network security is caused by the introduction of distributed systems, networks, and facilities for data communication. Improved network security is required because of the rapid development of communication networks. Network security is achieved by using softwareand hardware-based solutions and tools.

The Importance of Network Security in Protecting Sensitive Data and Information

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.

Network security has become a key issue in today’s world of technology. Network administrators need to keep up with the recent advancements in both the hardware and software fields to prevent their as well as the user’s data. This article aims to identify the need for network security and the various threats that are present today with respect to networking computer systems.

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT

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...

With the ushering in of the information age, a wide range of technologies in the field of computer science have emerged such that many network techniques are broadly utilized in different sectors of the society at large and in its wake not only has made great economic and social benefits, but also have immensely promoted the rapid development in culture and systems. While the openness and adaptability of computer network has brought us a ton of benefits both throughout our lives and work, it also has caused a series of information security problems which put our life at risk. With the fast advancement of computer network technology, ensuring the security of the computer becomes a very essential factor that cannot be disregarded. Three major threats confronting computer network security include: threat from hackers, computer virus and denial of service attacks whiles some measures leading to the safety of the network also include legal measures, technical measures as well as management measures. This paper seeks to investigate the primary risk confronting computer network security, address system security innovations and advances to help tackle the shrouded risk of the current basic system security.

Network protection is the movement of safeguarding data and data frameworks (organizations, PCs, information bases, server farms and applications) with fitting procedural and mechanical safety efforts. Firewalls, antivirus programming, and other mechanical answers for protecting individual information and PC networks are fundamental however not adequate to guarantee security. As our country quickly constructing its Digital Framework, we should teach our populace to work appropriately with this foundation. Digital Morals, Digital Wellbeing, and Network protection issues should be coordinated in the instructive cycle starting at an early age. Security counter estimates assist with guaranteeing the privacy, accessibility, and respectability of data frameworks by forestalling or moderating resource misfortunes from Network safety assaults. As of late network safety has arisen as a laid out discipline for PC frameworks andinfrastructures with an emphasis on security of important data put away on those frameworks fromadversaries who need to get, bad, harm, obliterate or disallow admittance to it. An Interruption Discovery Framework (IDS) is a program that examinations what occurs or has occurred during an execution and attempts to find signs that the PC has been abused. A large number of illustrations was thought of, including those connecting with: military and different kinds of contention, organic, medical services, markets, three-layered space, and actual resource security. These thusly prompted thought of various potential methodologies for improving network protection later on. These methodologies were marked "Heterogeneity" ,"Rousing Secure Way of behaving" and "Digital Wellbeing" . Network protection assumes a significant part in the improvement of data innovation as well as Internet providers. Our consideration is generally drawn on "Network protection" when we catch wind of "Digital Violations". Our most memorable idea on "Public Network protection" subsequently begins on how great is our foundation for dealing with "Digital Wrongdoings". This paper center around digital protection arising patterns while taking on new advancements, for example, portable registering, distributed computing, web based business, and informal communication. The paper additionally portrays the difficulties because of absence of coordination between Security organizations and the Basic IT Framework.
