Networks Are Ideal Targets For Hackers

The purpose of this paper is to touch on the issue of Hacking. It will go into detail about the history, evolution, future and prevention of Hacking. In addition, this paper will discuss different types of hackers and their motivation behind hacking. This paper examines the major impact caused by malicious hackers and give modern examples of such attacks. To conclude, it will predict how hacking will be in the near future and give the precautionary measures Information Security professionals can take to mitigate the risk of being victimized.

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

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

In general, wireless routers control access to their management interface by using the hypertext transport protocol (HTTP) as the default authentication protocol. In other words, when you connect to your wireless router from a web browser (typically http://192.168.1.1), and then submit your login credentials, the HTTP protocol is used to transmit your login credentials to the router. Because HTTP does not provide encryption, your login credentials are sent to the router over the air in clear-text. In this case, an attacker eavesdropping on your WLAN would be able to capture this information and use it to access the router as an administrator. Once your router is compromised an attacker can then use it to stage attacks such as man-in-the-middle (MITM), modify unencrypted data, or even send users to evil twin websites.

Wireless security in 802.11 is less robust and has many security flaws that can be exploited by an attacker. Security best practice for wireless networks depends on a defense in depth strategy, with five control layers:

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Wireless attacks have becoming a more common security issue when it comes to networks. Attacks can get a lot of information that is being sent across a network and use to commit crimes in other networks. Every wireless network is vulnerable to attacks and it is the important that all the necessary security measures are taken so as to prevent the mess these attacks can cause. These attacks are normally carried out to target information that is being shared through the networks. It is therefore very important to know of such attacks so you will be able to identify the attack when it happens.

The US should not retaliate in a cyber-war because it can cause lots of damage to our water supply, cellphone towers, trains, airport landing lights, and even our daily lives. If we were to go to war with Russia or another country that is more experienced in hacking, the results would be terrible. The other country would be able to malfunction our airplane equipment. They could make the plane go out of control, malfunction the landing gear, or take complete control over the plane. They could hack into our banks and take our money which would leave the country in debt. They could damage the stock markets and make any company go down dramatically in business.

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.

An article published by TheWeek.com titled Inside America’s Hacking Epidemic states that cyberattacks initiated by hackers is a growing threat that could lead to a number of serious problems. Some of these problems include the shutting down of the electrical grid and water supply. The author writes, “These cybercriminals can potentially target every aspect of our lives that involves an internet connection. They could suddenly apply the brakes on smart cars or take over a passenger jet’s avionics system.” In this passage, the author is trying to convey that there are many things that hackers can do to cause chaos. Some countries, such as Russia and China, sponsor hacking groups. Hacking groups such as Cozy Bear and Guccifer 2.0 are some examples of hacking groups sponsored by Russia. In conclusion, the author believes that cyberattacks are becoming more threatening and can be catastrophic to all aspects of society.

This examination is worth 20 percent of your total grade. There are five questions, and the maximum point values are included with each question.

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.

Hacking is the process of gaining unauthorized access to information through various means like systems or computers. In the context of computer security, a hacker is that person who looks for weakness in a system so that they can gain access to unauthorized information. They are motivated by various reasons like protest, profits or evaluating the entire system weaknesses.

In late 2016 the entire Internet was shaken by an attack of proportions that had never been seen. Although the type of attack at ground level was nothing new or too complex, the scale and method of delivering the attack caused all internet security researchers to take a moment of pause. Mirai, a previously known “botnet” that had affected other institutions such as Krebs on Security and OVH earlier in the year, is a massive army of recruited Internet of Things (IoT) devices ranging from in-home DVRs to simple webcams used for teleconferencing and home monitoring (Antonakakis, April, & Bailey, 2005). With a recruited army reaching over 600,000 devices, the infected devices spread across the globe ultimately crippled the Domain

As a distributed system with a number of nodes working together, a Big data cluster relies on the interconnect to communicate between Data Nodes and Name Nodes. The system also needs to extract data from data sources via the network. Thus, the security of the network is critical to the Big data system. The threats relevant to the network include DNS spoofing, eavesdropping attack and Denial-of-Service attacks, Man-In-the-Middle attacks, etc.
