The Cyber Security Vulnerabilities Faced By Different Networks

Organizations should develop a security policy for the wireless LAN infrastructure prior to the implementation stage. In order to have a strong security policy,

The vulnerabilities of wireless networking may involve the attack of web browsers, on-line banking, DNS servers, and routers exchanging routing table updates, purchases, transactions or stolen personal data. The lack of security with a wireless system may result in denial of service, hijacking, fake impersonation, or eavesdropping for interception of messages through cyber-crimes. Each communicating user should select the language of cryptography, agree and share the symmetric key. The best security practices includes firewalls, intrusion detection systems, secured and updated applications, transport, configured properly working network, and link layers.

Abstract -This paper addresses the internal and the external security challenges in organizations that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff and students. A description of the technique used to protect and keep PC 's up and running is illustrated with applications.

Wireless connectivity is critical to most homes and corporations as the world advances in technology. The technology has grown to a capacity that allows for extreme growth in wireless infrastructure as well as a trend of bringing your own technology device. Many corporations experience a high volume of critically important information being transferred over it wireless network so security is essential. There are many differences between a home and corporate wireless installation and each has its differences in securing.

Society has become dependent and subjected to the new development of computer innovations. As innovation advances, securing data frameworks threats and vulnerabilities risk increases which forced organization to compete with growing concerns to protect their information systems. Vulnerabilities in data frameworks may not be the only exist in unpatched applications or through that the deployment of malware which cause prompt breaches. The human component shockingly can be a damagingly reason which can cause cybersecurity breaches. Careless personnel are a huge contributing element in which adds to the cybersecurity vulnerabilities. User management console must be utilized to control the unknown threats of personnel, users, accessing their information

As technology has advanced throughout the years, so has the threat of infected devices compromising enterprise networks. For the most part, the main focus has been to secure the perimeter of the network. This leaves the interior of the network vulnerable to allow attack to originate. This threat has increased exponentially as the use of cell phones, laptops, tablets, among others, has increased as well. Since these mobile devices can be used on unsecure networks such as wireless hotspots, they have the potential to bring viruses, worms as well as other malware into the enterprise network.

Within this article, the authors states that in order to provide a safe and secure wireless network, they outlined the counter attacks and measures for the security of wireless networks. Some of the counter attacks that the authors have listed includes, system security - which breakdowns to administrative level security, physical level security, and technical level security, and information security (Ameen et al, 2012). For the purpose of answering the previous question, the main counter attack that would best defend against the problems would be system security - particularly the administrative level security. At this level of security, administrative control over the system by establishing a well defined user hierarchy plus a strong authentication measures, can prevent security breaches of WLANs from

The Department of Homeland Security realized its in-ability to protect key assets and critical infrastructure if it perused a government alone approach and has focused on partnerships. A government alone approach, as Michael Chertoff, Secretary of the US Homeland Security, noted is not sustainable "It is beyond Washington's means to assume the burden of micromanaging every critical business activity in the United States or supplying sufficient personnel to guarantee a reduction in the vulnerabilities of these activities." (Chertoff, 2008-09). To effectively protect key assets and critical infrastructure DHS focus on equal public-private partnerships.

Two factors increase the stakes of the cyber struggle. Tactically and operationally, the increasing dependence of modern technologically advanced forces (especially U.S. forces) on networks and information systems create new kinds of exploitable vulnerabilities. Second, as modern societies including the militaries that mirror them have continued to evolve, they have become ever more dependent on a series of interconnected, increasingly vulnerable “critical infrastructures” for their effective functioning. These infrastructures not only have significantly increased the day-to-day efficiency of almost every part of our

It requires maximum effort to ensure secure boundaries of this company’s network from. After people, information is our greatest asset which is why it would be in the company’s best interest to invest in its protection. When we take the defensive approach we tend to attempt thinking along the lines as an attacker. It’s helpful to be familiar with several of the tools that are made available to them and the ways these devices are used. More often than not an attack is planned. These incidents happen in segments and there is a method to an attackers approach.

Our society is becoming more and more reliant on wireless connections. The ability for both employees and consumers to connect wirelessly is a must in this day and age for businesses. Because of this, strict security policies must be put in place in order to keep the business and its data secure. This paper will discuss the pros and cons of wireless connections, the need for authentication and six top threats that companies should be aware of and how to prevent them.

IV. Overview of the many possible threats/risks that both home and corporate WIFI networks will need to overcome to provide the desirable level of security.

Wireless devices, like all technologies that provide external access to corporate networks, present security challenges. With wireless standards and practices still rapidly evolving, it is important to understand the strengths and limitations of available technologies in order to implement a secure solution. Extending current security policies to encompass wireless devices requires an understanding of the security features of both wireless devices and wireless networks.

Data which are kept by a company are vital and its protection should be a priority to networking administrator or network engineering. The company network can be invaded by both internal and external attack. It's estimated that up to 80% of all attacks against IT systems originates from the internal network, and are carried out by trusted fellow employee, deliberately to harm the company or the company employees Therefore, network security can be defined as the process in which digital information are protected against any attacked (IATA, 2011).

There are threats to network security that can compromise your computer systems. Viruses are one of the top security threats in the technology industry. A virus is a program or a code that is loaded into your computer system without your knowledge will run against your wishes (Beal, n.d). Viruses can also replicate themselves. All computer viruses are manmade and a virus can make a copy of itself several times and easy to create (Beal, n.d). Mark Vernon wrote that 72% of all companies have received infected e-mails or files last year and for larger companies the percentage was 83% (Vernon, 2004). The top viruses in malignancy are Worms and Trojan Horses (Vernon, 2004). Another threat to network security is malware. Malware (malicious software) is a annoying or harmful type of software that is intended to secretly access a device without a user’s knowledge. There are different types of malware, which include spyware, phishing, viruses, adware, Trojan horses, worms, ransomware, rootkits, and browser hijackers (“What is Malware and how to remove it | Cyber security,” n.d.). Malware gets access to your device through the internet, email, hacked websites, toolbars, music files, free subscriptions, toolbars and anything downloaded from the web (“What is Malware and how to remove it | Cyber security,” n.d.). Spam is also another threat to network security. Spam is a unsolicited message that advertises a service or product. Spammers target email accounts but can also be found on
