INTRODUCTION : The world is becoming more interconnected with the advent of the Internet and new networking technology. There is a large amount of personal, commercial, military, and government information on networking infrastructures worldwide. Network security is becoming of great importance because of intellectual property that can be easily acquired through the internet. When considering network security, it must be emphasized that the whole network is secure. Network security does not only concern the security in the computers at each end of the communication chain. When transmitting data the communication channel should not be vulnerable to attack. Definitions – Computer Security : generic name for the collection of tools designed to protect data and to thwart hackers – Network Security : measures to protect data during their transmission – Internet Security : measures to protect data during their transmission over a collection of interconnected networks Consider 3 aspects of information security: – Security Attacks – Security Services – Security Mechanisms Security Attacks – Any action that compromises the security of information owned by an organization – Often threat & attack used to mean same thing types of Attacks – Passive Attacks : attempt to learn or make use of information from the system but does not affect system resources – Active Attacks : attempt to alter system resource or affect their operation Security Threats Threats can come from a range of
Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also
In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in
Security is almost certainly the most difficult aspect of a network to perfect. It is important to have the correct procedures and components in place to make certain network security is being accounted for and addressed on any given network. The journal, “Future Generation Computer Systems” elaborates on this necessity for an information system. “Future Generation Computer Systems”, this component of a network is discussed thoroughly. “Essentially securing an Information System (IS), involves identifying unique threats and challenges which need to be addressed by implementing the appropriate countermeasures” (Dimitrios Zissis, Dimitrios Lekkas, 2012). This was achieved through configuring access lists as well as CHAP configuration on the routers connecting to the edge
I am Professor Kirk Mooring and I will be your instructor for this class. In this class, you will learn the fundamental core theories of information and network security. In this course, you will learn and use technology skills that are in demand in today’s job market. With so many threats and vulnerabilities created daily that we have to learn to work as a team in order to protect our data with the appropriate security safeguards. You will study the concepts that will help you evaluate and mitigate risk by selecting the appropriate security controls and technologies.
Information is the most valuable commodity that individuals and global corporations use to grow financially, economically, and independently. The protection and security of the information is essential. One of the most vital foundations of protection information is the authentication process. The authentication process is utilized to protect computer and network systems against various types of security threats, such as password-cracking tools, password dictionary attacks, mistreatment of user access rights, and any potential unauthorized attacked. Understanding how to authenticate users and the accessible information that is readily available on system networks can help prevent future issues as well as provide insight into the developmental process for new systems. In addition, authentication is simply determining whether someone or some machine is, in fact, who or what they declared there to be. This process directly reflects on and correlates to the readiness and ease of access to information and the protection of it.
Network Security Issues – major threats and the means to fight them Network security issues are the top priority of all who want to protect their data.
Security in the age of internet has become a tremendously important issue to provide comfort not only for paranoid people but for many others who are naïve to believe that protection in digital era is essential to communication between millions of people that increasingly used as a tool for commerce.
“Securing a computer system has traditionally been a battle of wits: the penetrator tries to find
In Conclusion, individuals and organizations today face a variety of security threats. To protect themselves from these threats, they usually take certain protective measure commonly known as safeguards. Some important safeguards are technical safeguard, human safeguard, and data safeguards. Using this measure as precautions help the organization from this types of security treats that help the organizations keep information private at all
Defense in depth minimizes the probability that the efforts of malicious hackers will succeed. A well-designed strategy of this kind can also help system administrators and security personnel identify people who attempt to compromise a computer, server, proprietary network. Some of the things that make up a defense in depth are antivirus software, firewalls, anti-spyware, strong passwords, intrusion detecttion, biometrics and much more (Rouse, 2007).
This paper was prepared for Network and Security Systems, CISK 445, taught by Dr. Marco A. Villarreal
Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.
The correct configuration of security technologies is mandatory to balance the need for access and safety of information (Cavusoglu & Raghunathan, 2009). Many companies use the layered approach to ensure protection of their network information system (Cavusoglu & Raghunathan, 2009). By using this approach, many security technologies rely on each other to operate effectively (Cavusoglu & Raghunathan, 2009). Three technologies commonly used together are Intrusion Detection Systems, Intrusion Prevention Systems, and firewalls. When configured properly, these technologies complement each other (Cavusoglu & Raghunathan, 2009).
As networks continue to increase with industry growth, information security demands more and more attention. Security breaches are triggering a lack of trust among patrons and loss of revenue to many businesses. Protecting an organization’s data is the responsibility of any user who accesses a network or maintains a network. Employees—usually those outside the IT team—require proper training and a sense of urgency to prevent attacks.
Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.
