How to detect operating system using user agent

In computing, a user agent is software (a software agent) that is acting on behalf of a user. For example, an email reader is a mail user agent, and in the Session Initiation Protocol (SIP), the term user agent refers to both end points of a communications session.<br />
<br />
In many cases, a user agent acts as a client in a network protocol used in communications within a client–server distributed computing system. In particular, the Hypertext Transfer Protocol (HTTP) identifies the client software originating the request, using a "User-Agent" header, even when the client is not operated by a user.<br />
<br />
<h1>
Standard User Agent browser</h1>
Most Web browsers use a User-Agent value as follows: <i>Mozilla/[version] ([system and browser information]) [platform] ([platform details]) [extensions]</i>. For example, Safari on the iPad has used the following:<br />
<br />
<pre>Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 
(KHTML, like Gecko)Mobile/7B405</pre>
The components of this string are as follows:<br />
<ul>
<li><i>Mozilla/5.0</i>: Previously used to indicate compatibility with the Mozilla rendering engine</li>
<li><i>(iPad; U; CPU OS 3_2_1 like Mac OS X; en-us)</i>: Details of the system in which the browser is running</li>
<li><i>AppleWebKit/531.21.10</i>: The platform the browser uses</li>
<li><i>(KHTML, like Gecko)</i>: Browser platform details</li>
<li><i>Mobile/7B405</i>: This is used by the browser to indicate 
specific enhancements that are available directly in the browser or 
through third parties. An example of this is Microsoft Live Meeting 
which registers an extension so that the Live Meeting service knows if 
the software is already installed, which means it can provide a 
streamlined experience to joining meetings.</li>
</ul>
Notable exceptions include Opera, which is a web browser, but does not include Mozilla in its User-Agent string.<br />
<br />
<h1>
Window User Agent</h1>
<pre>Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0</pre>
<ul>
<li><i>Windows NT 5.1; </i>: Window XP operating system as platform</li>
<li><i>Firefox/5.0</i>: Mozilla Firefox version 5.0 as a browser</li>
</ul>
<br />
<pre>Mozilla/5.0 (Windows NT 6.0) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.120 
Safari/535.2</pre>
<ul>
<li><i>Windows NT 6.0</i>: Window Vista operating system as platform</li>
<li><i>Chrome/15.0.874.120</i>: Google chrome version 15.0.874.120 as a browser</li>
</ul>
<br />
<pre>Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0)</pre>
<ul>
<li><i>Windows NT 6.1</i>: Window 7 operating system as platform</li>
<li><i>MSIE 10.0</i>: Internet explorer version 10 as a browser</li>
<li><i>WOW64;</i>: A 32-bit window application is running on a 64-bit processor</li>
</ul>
<br />
<pre>Mozilla/5.0 (Windows; U; Windows NT 6.2; en-US) AppleWebKit/533.20.25 (KHTML, like Gecko)
Version/5.0.4 Safari/533.20.27</pre>
<ul>
<li><i>Windows NT 6.2</i>: Window 8 operating system as platform</li>
<li><i>Version/5.0.4 Safari/533.20.27</i>: Safari version 5.0.4 as a browser</li>
<li><i>U;</i>: Security value (N for no security, U for strong security, I for weak security)</li>

How your Browser Speeds up Cross Domain Loading using DNS Prefetching

<strong>How it Works</strong><br>
What DNS prefetching does is attempt to resolve domain names before 
we, the  users, try to follow a link. This is accomplished using the 
computer's built-in  DNS resolution mechanism. Once a domain name has 
been resolved, if we do  navigate to that domain, there will be no 
effective delay due to DNS resolution  time. While downloading speed 
remains the same, looking up the IP address before  hand will save you 
an easily perceptible second or two when going from page to  page. A 
good example where DNS prefetching can really help is when a user is  
looking at a page with many links to various domains, such as a search 
results  page. When the browser encounters an a hyperlink that does not 
share the same  domain name as the current location, it first checks its
 cache and then, lacking  a cached copy, resolves the domain to the 
associated IP address through a  request from a DNS server. These 
requests happen in the background so as to not  block the rendering of 
the page. Moreover, since all this takes place in  parallel with the 
user's reading of the page, it places only a negligible load  on CPU and
 network resources. How much navigation time will a user save can  range
 from an average savings of about 200 milliseconds for non-cached 
content,  to one to two seconds for the worst DNS resolution delays.<br>
By default, prefetching of embedded link hostnames is not performed 
on  documents loaded over HTTPS. You can change this by setting the  
network.dns.disablePrefetchFromHTTPS browser preference to false.<br>

New Standard Pushes for a More Secure Web

There is no silver bullet when it comes to encryption. Even the most complex, invulnerable encryption today could be child’s play in the future. The NIST (National Institute of Standards and Technology) is <a href="http://www.pcworld.com/businesscenter/article/260922/new_nist_encryption_guidelines_may_force_federal_agencies_to_replace_old_websites.html">publishing new encryption standards</a> for public review to try and keep up with the times and stay a step ahead of the bad guys. <br>
<a href="http://images.pcworld.com/images/article/2012/04/secure_browser-11351369.jpg"><img alt="" height="227" src="http://images.pcworld.com/images/article/2012/04/secure_browser-11351369.jpg" width="320"></a>The NIST is a government agency, and its guidelines only really impact other government agencies. However, many security experts and organizations look to the NIST standards as a baseline. <br>
All of security is more or less a game of cat and mouse. Security measures are put in place, and they work for a while until attackers find the weak spots, or figure out how to compromise or circumvent them. Then, security experts have to devise new methods, and the game starts over. Website encryption, and the certificates we use to prove a site is legitimate, are subject to this same cause and effect.<br>

Defcon Wi-Fi Hack Called No Threat to Enterprise WLANs

<p>Enterprise Wi-Fi networks can keep using WPA2 security safely, despite a <a href="http://www.networkworld.com/news/2012/072912-tools-released-at-defcon-can-261242.html">recent Defcon exploit</a> that has been widely, but wrongly, interpreted as rendering it useless. <p>The exploit successfully compromised a legacy authentication protocol, MS-CHAPv2, which was created by Microsoft years ago. But the vulnerabilities of this protocol (and other similar ones) are well known, and Wi-Fi Protected Access 2 makes use of additional mechanisms to protect them. That protection is still in force, according to both the Wi-Fi Alliance and a wireless architect, who blogged in depth on this issue after the Defcon exploit was reported. <p>IN PICTURES:&#160;<a href="http://www.networkworld.com/slideshow/58324">Quirkiest moments at 2012 Black Hat security conference</a> <p>In the wake of the Defcon demonstration, enterprises were being urged by some to abandon MS-CHAP, the Protected Extensible Authentication Protocol (PEAP), WPA2 or all of the above. None of that is necessary. <p>The Wi-Fi Alliance has reviewed the chapcrack tool and cloudcracker service announced last week at Defcon 20 and these tools do not present an exploitable vulnerability in Wi-Fi CERTIFIED products, according to statement issued by the Wi-Fi Alliance, via Kelly Davis-Felner, the WFA marketing director. These tools exploit previously-documented weaknesses in the use of Microsoft CHAP (MS-CHAP).&#160;All uses of MS-CHAP in WPA2 are protected by the Transport Layer Security (TLS) protocol. TLS is the same strong cryptographic technology that protects all online e-commerce transactions. TLS prevents interception of the MS-CHAP messages used in WPA2 Enterprise and effectively protects against attacks using chapcrack or cloudcracker.</p> </p></p></p></p>
