Discuss about the Network Security and Preventive Techniques.
The wireless networks are among the major problems in the computing and information technology that are susceptible to several security threats as well as attacks (Liang & Yu, 2015). The areas of the wireless network usually involves the transfer of the information hence needs security in order to ensure that organization information has not been breached. Wireless networks could be secured via different means which are discussed in this report.
Overview of the technology involved
The wireless technology in their simplest perception allows one or perhaps more devices to connect without the physical connections and would not require the network or perhaps the peripheral cabling (Liang & Yu, 2015). The wireless technologies utilize the radio frequency transmission as their means for the transferring of the data, whilst the wired technologies utilize the cables. The wireless technology for the majority of the cases ranges from the intricate systems for example the Wireless Local Area Networks (WLAN), the cell phones to the simple devices for instance the wireless headphones, microphones and other devices in particular the remote controls, or perhaps the store information. Additionally, they might also consist of the isolated controls, some cordless computer keyboards and mice and wireless hi-fi stereo headphones.
Relevant technologies and applications of those technologies In undertaking research on the wireless security and preventive methods, the scope of the area network technology were used (Stallings, 2016). The numerous tools were employed locally in the coverage. These types of tools include the switches, computers and network. Other tools that are employed for the communication within the local network were also considered (Liang & Yu, 2015). Without any doubt, the wireless technology has been relevant and a vital component when it comes to the computer and the telecommunication world along with the Wireless third generation network which offers an increase in the benefits to various networks. The WLAN and the wireless technologies are the ones which have been identified to have great potential to the value of the custome r(Pierson & DeHaan, 2015). 3G is regarded as the standard which defines the technology which could provide the bandwidth wireless access over the large area as well as support to different services for example the WLAN, and roaming which is the disruptive technology which offers a much higher bandwidth within the smallest areas.
The wireless security technologies are Wi-Fi Protected Access, WiFi-Protected Access 2 and Virtual private networking (Pierson & DeHaan, 2015). The WPA and WPA 2 are essentially the based security certification from the Wi-Fi alliance for an organization, SMB as well as the small office Wireless LANs which offers a mutual authentication to verify on the personal users as well as the advanced encryption (Pierson & DeHaan, 2015). WPA usually offers an organization class encryption as well as WPA 2. It has been recommended that the WPA or the WPA 2 be utilized for the enterprise as well as the SMB wireless LAN deployments (Pierson & DeHaan , 2015 ) . WPA and WPA2 provide protected access control, a powerful data encryption and also simultaneously protecting of the network from any specific the active attacks. On the VPN provides an effective security to the customers’ wirelessly accessing network during the road and off from the office (Pierson & DeHaan, 2015). Utilizing the VPN the customers might make a secure tunnel between 2 or more points on the networks using encryption, although the encrypted data has been transmitted over the unsecured networks for instance the public internet.
There are different security issues which have affected the wireless networks over the last few years Stallings, 2016). It is known that an individual without comprehension of the networks can easily establish a flawed and vulnerable network. For that reason, it is very important remember that even their system administrators might lack understanding to the wireless network implementations (Stallings, 2016). Currently there are various security challenges which affect the wireless networks these are highlighted as follows;
In the DDoS attacks, a hacker set up an application on the machine which afterwards along with the other wireless networking systems might be called to take part in the attack (Stallings, 2016). Considering that the DDoS attacks normally provide heavier volume of the messages they have got the prospective to be much disruptive compared to simple DoS attacks that could derive from one particular computer (Stallings, 2016). In any given attack it might develop on the veritable army of the zombie systems that are accustomed to launch the attacks at will.
This is essentially an accessibility point that is included with a network without one understanding. A person does not need the knowledge that it is there. This is an access point which could generate some huge security issues. One is due given it could be simple to plug in the wireless gain access to point in it. In case one does not do any type of the network access control protocol on ones coverage, it might turn out to be easy for the additional workstations and gain access to reveal be incorporated with a network.
The wireless interference translates to disruption of one’s network. This really is an exceptionally significant problem particularly owing the fact that the wireless signals could possibly be disrupted. This kind of the disturbance might be established by utilization of a Bluetooth headset, a microwave or perhaps a cordless phone. This might generate the transmission and receiving of the wireless networks to be a challenge.
A wireless evil twin usually comes into the play whenever the criminals are trying to generate a rogue access points to be able to gain a having access to the network or simply access to the information employed via the network. Determining the evil twin can be quite easy given that all one demands would be to obtain a wireless access point, connect it into the network after which configure it exactly as the current existing network . This is feasible when it comes to the open access point which does not have any kind of passwords which are associated to them.
When the data has been sent back and forth over the coverage, it is sent out to the packet. Given that the wireless traffic is dispatched over the air, it would be simple to capture. One can find plenty of the traffic which is sent over the air which means there is certainly absolutely no encryption and the files are in the plain text for virtually any person to check out. There is plenty of the traffic which is sent in the clear meaning there is certainly simply no encryption and files are in the plain text for any individual to read. Utilizing a tool for example the Wireshark allows somebody to read the data transfers in the plan text. This might lead to stolen passwords or leakages of the sensitive information much conveniently. The data which is encrypted may be captured.
When a person goes remote, it is important to scramble the data you are sending to the remote system, to enable the hackers not access to the data. The use of encryption helps to scramble the data which is sent into the code which prevents others from opening it. The use of the encryption is the ideal technique to secure the system from the hackers. The two most types of encryption technologies are Wi-Fi Equivalent Privacy and the Wi-Fi Protected Access. WPA2 is easily the most technology which is secured and its utilization is applied on uncommon chances whenever that decision is reached. The encryption algorithm for most of the time shields the network against the standard software engineers (Liang & Yu, 2015). The WEP encryption algorithm just happens to be working in certain seasoned switches, wherein there is certainly absolutely no shielding against particular programs from the hackers. Access should be only permitted to certain gadgets in order to gain access to the remote system. Each device which speaks with the method is a Media Access Control. The isolated system generally allows specific gadgets with a particular MAC location to get access to the system.
It is essential to protect system from attackers, over the internet by preserving the switch protected. The switch is able to coordinate on the activity between nearby application and the web. This is the first step to safeguard against any attack. In the event that the switches are not secure, hackers can access the delicate data from the gadget and they are able to seize the control of the switch and direct the network to the deceitful sites. There is need to change the switch name from the default one. Following the advancement in the technology, it is important to ensure security to the switches through periodic updates.
The remote switch generally comes preset with the default secret key. Whenever setting an excellent secret key for the remote system, it is very important to make sure that it is certainly not less than twenty figures in length and it includes numbers, letters and distinct images (Stallings, 2016). With this setting it could keep other individuals from getting to the system.
When it comes to cryptography it protects the messages from being captured by parties which are unauthorized (Stallings, 2016). This technique enables concealment of the message which is sent and if it is certainly not discovered it makes the sender and receiver invisible. The use of the technique provides security and at the same times some anonymity. All the information hiding techniques which could be used to exchange the steganogram in the telecommunication network is described by the use of this technique (Wright & Cache, 2015). The network steganography usually uses the communication protocol to control the elements as well as their intrinsic functionality.
In the research report there are numerous issues which have been addressed; these are on overview of the technology involved. The report has addressed on different wireless network technologies and also their application (Wright & Cache, 2015). Challenges and the issues which lie within the wireless network have been addressed and the preventive techniques which could be used to address such issues from taking place in the future. These are important component in regards to this research to enable individual learn aspects related to the wireless network security which is becoming a major concern today and some individuals are not aware of how the attackers are exploiting the system due to advancement of the technology.
As much as the literature has highlighted on different aspects related to the wireless network security and preventive mechanism there are various issues which have not been addressed. Some of these issues relate to the fundamental of the wireless network and technologies which could be incorporated and show how the implementation of the security mechanisms are done. Moreover, there was need to show how each of the attack occurs and highlight on the methods which each could be addressed. There are different techniques which address each challenge in the system and this needed to be addressed in details. Moreover, there should have been practical examples highlighted to show how an attack occurs and how to prevent such attacks.
