Wireless security - Wikipedia. Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and Wi- Fi Protected Access (WPA). WEP is a notoriously weak security standard. The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 8. WPA, or Wi- Fi Protected Access.
WPA was a quick alternative to improve security over WEP. The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device that encrypts the network with a 2. WEP. Many laptop computers have wireless cards pre- installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security issues. Hackers have found wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.[1] As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.[2]Wireless Intrusion Prevention Systems (WIPS) or Wireless Intrusion Detection Systems (WIDS) are commonly used to enforce wireless security policies.
Description. Aircrack-ng is a complete suite of tools to assess WiFi network security. It focuses on different areas of WiFi security: Monitoring: Packet capture and. Alright, this post is written assuming you have Kali Linux up and running on your computer. If not, here is a post on hacking with kali linux. It will tell you about. Learn the difference between WEP, WPA and WPA2, and find out which of these wireless security protocols is best for your WLAN. Instead, you want long, weird strings that neither computers nor people can guess. Humans are bad at coming up with these—we all pick the same “random” words.
Security settings panel for a DD- WRT router. The risks to users of wireless technology have increased as the service has become more popular. There were relatively few dangers when wireless technology was first introduced. Hackers had not yet had time to latch on to the new technology, and wireless networks were not commonly found in the work place.
However, there are many security risks associated with the current wireless protocols and encryption methods, and in the carelessness and ignorance that exists at the user and corporate IT level.[3] Hacking methods have become much more sophisticated and innovative with wireless access. Hacking has also become much easier and more accessible with easy- to- use Windows- or Linux- based tools being made available on the web at no charge. Some organizations that have no wireless access points installed do not feel that they need to address wireless security concerns. In- Stat MDR and META Group have estimated that 9. Issues can arise in a supposedly non- wireless organization when a wireless laptop is plugged into the corporate network.
A hacker could sit out in the parking lot and gather information from it through laptops and/or other devices, or even break in through this wireless card–equipped laptop and gain access to the wired network. Background[edit]Anyone within the geographical network range of an open, unencrypted wireless network can "sniff", or capture and record, the traffic, gain unauthorized access to internal network resources as well as to the internet, and then use the information and resources to perform disruptive or illegal acts. Such security breaches have become important concerns for both enterprise and home networks.
If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot. Since most 2. 1st- century laptop PCs have wireless networking built in (see Intel "Centrino" technology), they don't need a third- party adapter such as a PCMCIA Card or USBdongle. Built- in wireless networking might be enabled by default, without the owner realizing it, thus broadcasting the laptop's accessibility to any computer nearby. Modern operating systems such as Linux, mac. OS, or Microsoft Windows make it fairly easy to set up a PC as a wireless LAN "base station" using Internet Connection Sharing, thus allowing all the PCs in the home to access the Internet through the "base" PC.
However, lack of knowledge among users about the security issues inherent in setting up such systems often may allow others nearby access to the connection. Such "piggybacking" is usually achieved without the wireless network operator's knowledge; it may even be without the knowledge of the intruding user if their computer automatically selects a nearby unsecured wireless network to use as an access point. The threat situation[edit]Wireless security is just an aspect of computer security; however, organizations may be particularly vulnerable to security breaches[4] caused by rogue access points. If an employee (trusted entity) brings in a wireless router and plugs it into an unsecured switchport, the entire network can be exposed to anyone within range of the signals. Similarly, if an employee adds a wireless interface to a networked computer using an open USB port, they may create a breach in network security that would allow access to confidential materials. However, there are effective countermeasures (like disabling open switchports during switch configuration and VLAN configuration to limit network access) that are available to protect both the network and the information it contains, but such countermeasures must be applied uniformly to all network devices. Threats and Vulnerabilites in an industrial (M2.
M) context[edit]Due to its availability and low cost, the use of wireless communication technologies increases in domains beyond the originally intended usage areas, e. M2. M communication in industrial applications. Such industrial applications often have specific security requirements. Hence, it is important to understand the characteristics of such applications and evaluate the vulnerabilities bearing the highest risk in this context.
Evaluation of these vulnerabilities and the resulting vulnerability catalogs in an industrial context when considering WLAN, NFC and Zig. Bee are available.[5]The mobility advantage[edit]Wireless networks are one of the most common technologies, both for organizations and individuals. Many laptop computers have wireless cards pre- installed. The ability to enter a network while mobile has great benefits. However, wireless networking is prone to some security issues.[6]Hackers have found wireless networks relatively easy to break into, and even use wireless technology to hack into wired networks.[1] As a result, it is very important that enterprises define effective wireless security policies that guard against unauthorized access to important resources.[2]Wireless Intrusion Prevention Systems (WIPS) or Wireless Intrusion Detection Systems (WIDS) are commonly used to enforce wireless security policies. The air interface and link corruption risk[edit]There were relatively few dangers when wireless technology was first introduced, as the effort to maintain the communication was high and the effort to intrude is always higher.
The variety of risks to users of wireless technology have increased as the service has become more popular and the technology more commonly available. Today there are a great number of security risks associated with the current wireless protocols and encryption methods, as carelessness and ignorance exists at the user and corporate IT level.[3] Hacking methods have become much more sophisticated and innovative with wireless. Modes of unauthorized access[edit]The modes of unauthorised access to links, to functions and to data is as variable as the respective entities make use of program code. There does not exist a full scope model of such threat.
To some extent the prevention relies on known modes and methods of attack and relevant methods for suppression of the applied methods. However, each new mode of operation will create new options of threatening. Hence prevention requires a steady drive for improvement. The described modes of attack are just a snapshot of typical methods and scenarios where to apply. Accidental association[edit]Violation of the security perimeter of a corporate network can come from a number of different methods and intents. One of these methods is referred to as “accidental association”. When a user turns on a computer and it latches on to a wireless access point from a neighboring company’s overlapping network, the user may not even know that this has occurred.
However, it is a security breach in that proprietary company information is exposed and now there could exist a link from one company to the other. This is especially true if the laptop is also hooked to a wired network.
