4 ways to identify secure Web sites on the Internet

Total Internet Web pages, there are approximately more than 150 million active operation. As a result, it becomes a real challenge for users to identify secure Web sites that are reliable and reputed. Have you ever wondered to know the reputation of a Web site before placing the order? You need to know if a particular Web site is safe kid? Well, here are some ways to identify secure Web sites on the Web.

 

WOT is a great place to check the reputation of your favorite Web site. WOT provides real-time ratings for each Web site on the basis of the comments that it receives from millions of reliable users across the globe and trusted sources, such as blacklists of phishing and malware. Each domain name shall be evaluated on the basis of these data and ratings shall apply mutatis mutandis. A snapshot of the WOT gohacking.com rating is shown below:

 

 

 

 

 

 

As shown in the above screenshot, the reputation of each Web site is displayed by the view of 4 elements which means Green, yellow excellent warns users to be cautious and red indicates a potential danger.

 

Reliability indicates the overall security of the website. A poor rating may indicate that the site is associated with threats such as Internet fraud, phishing, identity theft and malware.

 

Supplier reliability tells you whether a given site is safe to proceed to buy and sell transactions. An excellent rating indicates higher customer satisfaction, while a bad rating indicates possible fraud or bad experience.

 

Privacy says about "how far the site respectful of the privacy of users and protects their personal identity and data.

 

Child safety indicates whether the content of a particular site is suitable for children. Site content such as erotic material, nudity and obscenity have a bad score child safety .

 

In most cases, the WOT ratings are found to be highly accurate. To check the reputation of any given Web site, just visit www.mywot.com press-in your favorite Web page address, and click check now. Only this tool can tell a lot about the integrity and the safety level of a Web site. However, in addition to this, I will give you another 3 useful tools to identify secure Web sites on the Web.

 

2. McCafee SiteAdvisor:

McCafee SiteAdvisor is a free tool which is available as a browser add-on. Adds safety ratings to your browser and search engine results. This can be downloaded from the www.siteadvisor.com.

 

3. StopBadware:

Using this tool, you can check if a given site is said to have participated in activity of malware in the past. To check this, go to http://www.stopbadware.org/home/reportsearch and enter the URL or domain name from a Web site and click "Search Clearinghouse". If your search does not return any results, this means that the site has never participated in any activity of malware in the past.

 

4. Google Pagerank:

Google PageRank is another great tool to test reputation and popularity of a website. The tool PageRank rates each Web page on a scale from 1 to 10, which indicates the Google view of the importance of the page. If a particular Web site has a PageRank of less than 3, then is said to be less popular among the other sites on the Internet.

 

However, PageRank will only tell you how popular a particular Web site is and has nothing to do with the security level of a Web site. Thus, only this tool cannot be used for the evaluation of the safety of the website and other factors.

 

The PageRank feature is available as part of the Google toolbar. You can install the Google Toolbar from http://www.google.com/intl/en_uk/toolbar/ie/index.html.

Single-Atom quantum information stores

ScienceDaily (May 2, 2011) memory data could hardly be less than: researchers working with Gerhard Rempe at the Max Planck Institute of quantum optics in Garching has stored quantum information in a single atom. Scholars wrote the quantum state of a single photons, that is, the light particles into atomic rubidium, vrshm it again after a particular volume. This technique can be used in principle to design a powerful domain and to communicate them quantum with one another across large distances.

Quantum computers one day be able to cope with the computational tasks within a short time in which the current domain will take years. They would take the enormous computing power of their ability to simultaneously process diverse data items that are stored in the microscopic quantum physical systems, such as a single opaque vpotonim. In order to be able to run, you must replace these quantum computers are pieces of information between the various components. Photons are especially suitable to do this, as no matter what needs to be transported with them. Particulate matter however will be used for processing and storing information. Researchers are looking for and methods by which you can exchange information between photons and quantum. However already performed with ensembles of many thousands of atoms, physicists at the Max Planck Institute of quantum optics in Garching now proven that quantum information also can be controlled from a single photons to atoms.

Using a single atom that storage unit has several advantages: minimizes the extremists have only one, says Holger Specht mmboss-Garching Max-Max, which was involved in the experiment. You can process the information stored by direct manipulation baatom, which is important for performing logical operations, quantum computer. "In addition, it offers the opportunity to see if quantum information stored in the bapoton successfully written into the atom without destroying the quantum state," says Specht. Possible, make sure that you have to go early in the process of computing due to storage.

The fact that no one could very recently on quantum information exchanged between photons and atoms single was that interaction between the light particles and atoms very weak. Atom, the photon will not take notice of it, as it were, like two people barely speak to each other party, so replace only a little bit of information. Researchers in Garching have enhanced interaction with rotation. They assume the Atomic rubidium between optical resonator mirrors, and then use very weak laser pulses to introduce single photons into the cavity. Reflected photons in the cavity mirrors several times back and forth, which improved the interaction between photons and atom. Figuratively speaking, guests of the party and meet more often and increases the chance that they are talking to each other.

Photons carried quantum information in the form of polarization. This can be left (direction of rotation of the electric field is counterclockwise) or right (clockwise). Quantum state of the photon polarizations can be both at the same time as the superposition. Interact with the photon the atom rubidium is usually excited and then loses again the excitement of more probabilistic photon emission. Garching-based investigators did not want it to happen. On the contrary, the absorption of photon the atom could bring into the quantum state RB, steadily. The researchers at this with a laser beam, laser Control Panel, where they are directed to RB atom at a time when you interact with the photon.

Because the spin of the atom mabotiam contributes to stable quantum state generated by vapoton laser control. Spin gives the Atomic magnetic moment. Quantum state, the researchers use to store, and is determined by the orientation of the magnetic moment. The country is characterized by the fact that it reflects the State of polarization of a photon of the orientation: refers to the direction of the magnetic moment of the photon polarization cycle, a mixture of the two sides chshocmt being stored by the appropriate mixture of magnetic moments.

This is referred to as the reverse process: the Atomic rubidium with laser control panel again causes it to emit the photon re-which was the source of the event. The vast majority of cases, information Quantum Photon-out screens with information stored in the source, as physicists discovered in Garching. Quantity that describes this relationship, trust, was more than 90 percent. This is significantly higher than the 67 percent to fidelity can be reached with classical methods, that is not based on quantum effects. The method was developed in Garching is therefore a real quantum memory.

The physicists to measure the time storage, that is, the time quantum information may be retained, as RB-about 180 microseconds. "This is a parallel with times all quantum memories based on previous ensembles of atoms," says Stefan Ritter, a more involved in the experiment. Nevertheless, time is significantly more is required for the method used quantum quantum computer or network. There is also another quality characteristic of quantum memory in a single atom that can improve from Garching: efficiency. This is a measure of the number of photons are irradiated are stored, and then read again. It was just under 10 percent.

Storage time is mainly limited by the magnetic field fluctuations from the lab, said Ritter. "This is so you can zoom in by quantum information storage, quantum States of the atoms that they are sensitive to magnetic fields." effectiveness is limited by the fact that the atom to sit still in the center of the cavity, but passes. This causes the strength of the interaction between the atom photon to decrease. The researchers also helping improve the efficiency and effectiveness: by large cooling of the atom, that is, by its kinetic energy to another.

Researchers at the Max Planck Garching and now you want to work on these two improvements. "If this operation succeeds, the chances of a single Atom quantum memory is excellent," says Stefan Ritter. The interface between individual light atoms allow more quantum computer network atoms with this than be possible without such interface; The fact that such a machine to make stronger. Moreover, quantum mechanical photons will be possible across large distances and entangle atoms. Quantum entanglement is a type of mechanical link between the particles needed to transmit quantum information over large distances. It is currently in development at the Max Planck Institute of quantum optics, making that a critical element of the future "quantum Internet."

How to recognize and avoid phishing scams

Phishing is a form of social engineering technique used by attackers to obtain sensitive information such as usernames, passwords and credit card details, as one person/organization trustworty. Since most online users are not aware of the techniques used in the performance of a phishing attack, often the victims and therefore, phishing can be very effective.

With the dramatic increase in the number of scams in recent years, there was also a steady increase in the number of people who are victims. Lack of awareness of the population is the main reason behind such attacks. This article will try to educate users about these online scams frauds and irregularities and awareness.

Scams usually sends an e-mail message to users who request it for their personal information, or redirect to a website where they can enter their personal information. Here are some tips that can be used to identify various techniques of phishing and to stay away from it.

 

Identify a phishing scam

 

1. the attention of e-mail messages that require an urgent response on your part. Some examples are as follows:

• You may receive an e-mail message that appears to come from your bank or financial organisation that says "your bank account is limited due to unauthorized activity. Please Confirm your account asap to avoid permanent suspension ". In most cases, you are prompted to follow a link (URL) that takes you to a spoofed website (similar to your website Bank) and enter your logon information.
• In some cases, the phishing messages may ask you to make a phone call. There may be a person or an audio response to expect from the other side of the phone to take your credit card information, account number, social security number or other important data.

2. phishing e-mail messages is not generally personally. Since a lagre number aimed at the users online, usually using generalized texts like "Dear valued customer", "Dear Paypal user" etc., to address to you. However, some phishing messages may be an exception to this rule.

3. When you click on links contained in a phishing email, you will most likely be taken to a fake website with official logos and information that looks exactly like the original Web pages from your bank or financial company. Attention to the URL of a Web page before you enter any of your personal information. Even if they appear to be identical to the legitimate site malicious websites, often uses a different domain or variant spelling. For example, instead paypal.com's, a phishing website can use different addresses like:

• papyal.com
• PayPal.org
• Verify-paypal.com
• xyz.com/PayPal/Verify-Account/

 

Tips to avoid being the victim of phishing

 

1. Don't respond to suspicious emails that ask you to provide your personal information. If you are not sure whether an online request is legitimate, verify the same by calling the respective Bank/company. Always use the phone numbers that are printed in your Bank records or statements and not those mentioned in the suspicious e-mail message.

2. do not use links in email, instant messaging or chat conversation to enter a Web site. Instead, always type the URL of the Web site in your browser address bar to enter a Web site.

3. legitimate Web sites should always use a secure connection (https://) in these pages are intended to collect sensitive data such as usernames and passwords, account numbers or details, credic cards. You will see a lock icon in the address bar of your browser indicates a secure connection. On some Web sites such as paypal.com, which uses an extended validation certificate, in the address bar of GREEN triggers, as shown below.

 

 

In most cases, as opposed to a legitimate Web site, a Web site phishing or spoofed website will not use a secure connection and do not display the lock icon. Thus, in the absence of these security features can be a clear sign of a phishing attack. Always double-check the security features of the site before entering into any of your personal information.

4. always use a good antivirus software, firewall and email filters to filter out unwanted traffic. Also ensure that your browser is up-to-date with patches applied.

5. report a "phishing attack" or "spoofed" e-mails to the following groups to stop attacks from spreading throughout the Internet:

Directly, you can send an email to spam@uce.gov or reference of an attack to reportphishing@antiphishing.org. Also, you can notify the Internet Crime Complaint Center of the FBI by filing a complaint on their website at: www.ic3.gov.
