What cloud computing really means

 

Cloud computing is all the rage. "It's become the phrase du jour," says Gartner senior analyst Ben Pring, echoing many of his peers. The problem is that (as with Web 2.0) everyone seems to have a different definition.

As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing," the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud," including conventional outsourcing.

Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.

Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging.

InfoWorld talked to dozens of vendors, analysts, and IT customers to tease out the various components of cloud computing. Based on those discussions, here's a rough breakdown of what cloud computing is all about:

1. SaaSThis type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting. Salesforce.com is by far the best-known example among enterprise applications, but SaaS is also common for HR apps and has even worked its way up the food chain to ERP, with players such as Workday. And who could have predicted the sudden rise of SaaS "desktop" applications, such as Google Apps and Zoho Office?

2. Utility computingThe idea is not new, but this form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs, but one day, they may replace parts of the datacenter. Other providers offer solutions that help IT create virtual datacenters from commodity servers, such as 3Tera's AppLogic and Cohesive Flexible Technologies' Elastic Server on Demand. Liquid Computing's LiquidQ offers similar capabilities, enabling IT to stitch together memory, I/O, storage, and computational capacity as a virtualized resource pool available over the network.

How to Hack Windows Passwords With Ophcrack

 

 

 

Ah, the old "How do I get my lost user password back?". Well, this time I am happy to say that there is a way to recover your password WITHOUT reformatting your hard drive. First off, what operating system are you using? If you are using Windows or Linux the first solution will work for you.

Step 1: Download The Corect Verison

It uses Rainbow Tables to crack NTLM and LM hashes into plain text. There are two ways to run Ophcrack. One, it can be installed and run as a standard application. Two, you can burn the ISO to a CD and boot from the disk and run the Linux based GUI. In your case you would need to burn to a disk and boot from the disk drive. The first step would be to visit the Ophcrack website and download the LiveCD version of Ophcrack for the correct operating system
(http://ophcrack.sourceforge.net/download.php?type=livecd)

Step 2: Burn To ISO

Once you have downloaded the correct ISO you will need a program to burn the ISO. I recommend ISO Recorder(http://isorecorder.alexfeinman.com/download/ISORecorderV2RC1.msi)

Step 3: Start Cracking!

Once you have burned the ISO to a CD you will need to make sure the disk is in the CD drive and reboot the computer. Now when the computer is booting you will need to press the correct key to get you into the Boot Menu. It is usually F10 or Delete. Once in the boot menu select the disk drive that the CD is in. Now follow the on screen directions. After it gets to the menu press the "Crack" button and it will do its magic. In about 10 minutes it will tell you what the Password is. I hope this answers your questions.

This program needs access to your hard drive in order to work. You also need to install WinPcap, which comes with the installer. After downloading the Rainbow tables, extract the files (table0, table 1, etc.) into the Cain folder. The run the program. In the "Cracker" tab, click LM and NTLM hashes. The click the blue cross at the top toolbar and then click OK. this will dump all the users on the computer. Find the account you want to hack and right click on it. Then go to Cyptananylisis attack, LM Hashes and then to Rainbow tables. Click start and wait while the password is decoded. You can then tinker wth the many features of this program

How to Restore Folder Options in the Control Panel

 

 

Computer virus is a self-replicating executable program that damage or even destroy files or disks. It always occupies disk space and sometimes the main memory. There are different anti-virus softwares which can effectively remove viruses such as Norton, Avira, NOD32, Kaspersky, McAfee, AVG, Avast, etc. The different kinds of viruses are boot-sector virus, denial-of-service attack, e-mail worm, file virus, hoax, macrovirus, multipartite virus, etc.

Even though viruses have already been removed/deleted in your computer, it left damages to your computer. One of them is the changed attribute in your folders from archive/read-only to hidden. Thus, you will think that some of your folders have already been erased or deleted by virus and anti-virus. Just look at the status bar to see how many hidden folders in a particular drive or path in your computer.

If you will try to change again its attribute in the folder options at the control panel, you will be shocked to know that the folder options icon is missing. It has been removed in the control panel. It has been hidden together with some of your important folders. And even if you try to restore the folder options icon in the toolbar by customizing it, it has no use for you can never click it at all.

Of course, you can still see your hidden folders by using special program for compressed files called WinRAR, you can use it to delete *.exe made by the virus (* represents any name of your folder or file copied by the virus).

But there are many things which you want to do that cannot be done through WinRAR such as copying and pasting folders/files, viewing folders/files in thumbnails, etc.

The only solution is to restore the folder options in the control panel. In this instructable, I am going to teach you step-by-step how to restore folder options in the control panel. It will also appear in My Computer and its icon can now be used in the toolbar. Please be sure that all viruses have already been removed before you apply this advanced computer tutorial.

How to Choose a Good Password: A few quick tips on how to stay safe

 

 

 

Your password is more than just a key to your online account. If your password falls into the wrong hands, someone can easily impersonate you while online, sign your name to online service agreements or contracts, engage in transactions, or change your account information. So, choose your password carefully and then keep it safe from others.

A password is like a toothbrush: Choose a good one and don't share it.

A password can be any length, and can contain spaces, symbols, or numbers. With so many options, you should be able to come up with a password that's easy for you to remember but impossible for someone else to figure out. A password is a secret that only you should know.

Wanna make a good Password? Hit that next step button and find out how....

Step 1: How should that password be? What aspects should it have?

---

---

---

First and most important of all: A good Password should be memorable for you, yet hard for others to guess.

You might have the greatest Password on Earth, but It's worth nothing if you don't easily remember it!

A good example would be a celebrity's birth date. No one could guess that as a password, and you can easily look it up if you forget.

---

Avoid using a word. Avoid a complete word from a dictionary (English or otherwise) or a name.

You'd be surprised how easy it is for someone who knows you to guess your password. They know exactly what to expect, and what not to expect.

Example:

Use Psterboard instead of Posterboard

---

Use at least 10 characters.

The more characters your password contains, the harder it is for someone to guess it. A long but simple password can be safer than a short, complex one and often easier to remember.

Example:

Johnnywenttotheparkyesterday might be safer than 3iblesrules4

---

Use a combination of capital and lowercase letters, numbers, and standard symbols (! @ # $ % ^{& *).}

If the place that you want to create a password for differences capital and lowercase letters, be sure to use both. Even if someone hears your password, a different capitalization can make a difference.

Example:

Instead of automobile, write aUTomObile

---

Don't use personal information that someone could easily figure out.

Avoid a password based on information easily obtained about you (like your birthday, your child or pet's name, phone number, license plate number, employer, school name, automobile brand, or street name).

Don't use a password you already use for another account, such as your bank account PIN.

Like I said above, people who know you know what and what not to expect from you.

Example:

Try not to use your screenname as your password. Not even with Different capitalization or spelling.

---

Avoid the obvious.

This is where a lot of people screw up. People think that if they use a password thats not even a word or something along those lines, they'll be safe. People think that if they use something totally irrational, no one will expect that.

Stay away from obvious passwords such as "test" or "password."

When you change your password, change several characters; don't just append a number like "2" to the end. And make sure anyone watching you enter your password can't guess it as you type (such as a password typed using a single hand, like "qwerty").

Example/

Don't make it easy for attackers by repeating a digit or letter (like "111111" or "FFFFFF") or any other common sequence of characters (like "123456").

---

Put a new spin on a familiar phrase. MiX i+ Up!!

This is where you start mixing and experimenting with the above tips.

Pick a favorite phrase or lyric for your password.

To shorten it, substitute letters with a number or a standard symbol or remove vowels. For example, "fredsboy" can be made into "Fr3d$boy." Shorten "two tickets to paradise" to "2Tickets2Paradiz," or combine "cat" and "dog" into "cAt!Do8."

---

If you use a password generator, be careful.

Make sure you can identify and trust the creator of a password management or generator program. Never share any personal information unless you trust the company or person you're working with.

Online password-generator programs can help you create a random password that is generally harder to crack but also more difficult to remember.

Another factor to consider, is that sooner or later, you could find patterns in these, and eventually know what to expect.

Removing a virus without using any anti-virus software

 

 

Virus is a computer program that can copy itself and infect computers.
The term "virus" is erroneously used to refer to other types of malware, including adware and spyware programs that do not have the reproductive ability.
A true virus can spread from one computer to another (in some form of executable code).
One of the ways by which a virus can infect your PC is through USB/Flash drives.
Common viruses such as 'Ravmon' , 'New Folder.exe', 'Orkut is banned' are spreading through USB drive .
Most anti virus programs are unable to detect them and even if they do, in most cases they are unable
to delete the file, only quarantine it.So in our post we use command prompt to remove harmful files that
any anti-virus can't.


These are the steps.

Step 1:

 Run the command prompt by going to start and type cmd on the search programs and files.

Step 2:

 Select the virus affected drive
                 (drivename: )
examples
C:
J:
F:
D:
E:

Step 3:

 type attrib -s -h *.* /s /d then press enter

Step 4:

 type dir 
        the dir command shows you the content of the drive

Step 5:

check if there is an unusual .exe file
                 if there's an autorun.inf file rename it

                    (rename filename.extension newfilename )

Step 6:

by doing the following steps you can now acces the drive without affecting the virus

 Go to my computer

Step 7:

Select the drive

Step 8:

Delete the harmful files
             *you can also delete the harmful files using command prompt
              ( type del filename)
