Some of the types of communication technologies used also include email discussion groups, Usenet news, chat groups and etc. These are unique to networked computer environments and have come into wide popularity because of the Internet. Other technologies, including video and audio conferencing and Internet telephony, are also available on the Internet. Most of the technologies that are unique to the Internet require communication to be done in text letters with some symbols and punctuation. Communicating effectively involves taking the time, except in informal communications, to use correct grammar, spelling, and punctuation and writing an appropriate message. B) What are the steps you should take to improve the security of wireless networkIntroduction Today’s organizations increasingly rely on the mobility and lower cost of wireless networking. Schools K-12 and small to medium-sized businesses are investing in Wi-Fi to leverage benefits including more flexible network connectivity, improved productivity, and reduced capital expense.

As wireless local area networks (WLANs) become an operational standard, technologies are becoming more secure, faster, and easier to deploy and manage. Properly deployed, wireless networks can provide security that matches or exceeds that of the wired network. With advanced technology based on multiple layers of protection, governments and businesses are trusting confidential and business critical applications to run over WLAN 1. Using the Anti-virus softwareThe most Anti-virus, anti-virus, or AV software is computer software used to prevent, detect and remove malicious computer viruses. Most software described as antivirus also works against other types of malware.( Malware, short for malicious software, is any software used to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of executable code, scripts, active content, and other software. The Hacker can use the malware to enter your internet zone and get your information) So using the Anti-virus software is very important for the user of Wireless internet.

It can keep the malware away and keep security of using the wireless network. It can check and delete the malware in which your networking equipment such as lap-top or hand-phone. 2. FirewallThe meaning of firewall is a combination of software and hardware equipment made between the internal network and external network, the interface between the private network and the public network structure of the protective barrier. Was a way to get the image of the security argument, it is a combination of computer hardware and software, so that between the Internet and intranet establish a security gateway (Security Gateway), to protect the internal network from unauthorized users intrusion, firewall access rules mainly by the services, verification tools, packet filtering and application gateways four parts, a firewall is located between the computer and the network it is connected to software or hardware. The inflow and outflow of all computer network communications and data packets have to go through the firewall. In the network, the meaning “firewall” refers to an internal network and the public access network separate ways, it is actually an isolation technology.

A firewall is a visit to the implementation of the two network communication control scale, it allows you to “agree” and data into your network while you “do not agree” and shut out the data, the maximum prevent network hackers to access your network. In other words, if you do not pass through the firewall, inside the company who cannot access the Internet, people cannot be on the Internet and communicate with people inside the company. 3. Be careful to using the wireless network yourselvesThe first to points is using the software tools to keep the security. By the way, you also should be careful with yourselves. Try to never enter in the dangerous website and never connect with unknown Wi-Fi, When you using the public Wi-Fi, you should try to avoid to enter your network account.

If you have to enter it, you should cancel the key of remember the account password. These are the ways that keep security of wireless network by themselves. 4. Don’t broadcast your SSIDMost WLAN access points and routers automatically (and continually) broadcast the network’s name, or SSID (Service Set IDentifier). This makes setting up wireless clients extremely convenient since you can locate a WLAN without having to know what it’s called, but it will also make your WLAN visible to any wireless systems within range of it. Turning off SSID broadcast for your network makes it invisible to your neighbors and passers-by (though it will still be detectible by WLAN “sniffers”). 5. Shut Down The Network When It’s Not Being Used

A bit of advice is even more dependent on specific circumstances than most of them. If you have the sort of network that does not need to be running twenty-four hours a day, seven days a week, you can reduce the availability of it to security crackers by turning it off when it isn’t use. Shutting down your network will most certainly prevent outside hackers from breaking in. ConclusionMobile devices and technologies have permanently changed the way work is accomplished, allowing connectivity anywhere within the company as well as at home, in airports, hotels, and other Wi-Fi hotspots. With this freedom, new threats arise to the corporate network as wireless signals penetrate beyond walls and devices connect outside the relative safety of the company.

To maintain security, you can use anti-virus software that prevents and removes malicious computer viruses. And secondly, you can use Firewall that separates the private network and public network so that people on the Internet cannot communicate with people inside the company. Thirdly you have to be careful yourselves when you use wireless network. And then you must not broadcast your SSID . Finally, you can shut down the network when it’s not being used to prevent outside hackers from breaking in. Today’s wireless networks are helping institutions and cutting business costs, increase productivity and create new efficiencies in times of budget cuts. As they follow secure administrative practices, organizations small and large benefit from safe, reliable network connectivity. The right tools will assist in configuration changes and firmware updates to reduce user error and other threats.
