Java Database connectivity guide from DataBase Guide

Java database connectivity is basically an application that enables users to access pertinent data by the use of queries. The users can update significant information within the given database. The program supports the access to files from spreadsheets, flat files and databases transforming into backstage access to database independent to database management system used. Java database connectivity provides an easy to use platform by choosing the most appropriate platform to use. One simply needs to retrieve an object from the driver manager.

High availability usually describes a network and all of its components available for data input, processing and report. The system determines the success depending on planning and understanding the tolerance that would affect the network. Even at small corporation level, high availability is desirable and necessary. As system failure should not bring down the entire system, so fault tolerance is important measure of high availability system. Thus creating such a high availability system involving extensive planning with least potential failure is very important.

Disasters may occur naturally or man made and is usually difficult to predict their occurrence. Disaster recovery is the ability of a system to recovery its entire electronic data in shortest possible time interval. It involves a lot of forward planning and policy settings. Possibilities involve facing a number of threats like hacking, electrical failure, human error and natural disasters. Keeping off-site data backups may be sufficient for smaller corporations, but in case of a larger corporation it would be provisioned and costed as a part of their annual budget.

Merging two or more databases and producing a meaningful report is what we call as data integration. It is thought as a major headache for IT professionals. Databases are designed such that they suit the need of the software used and not for merging purposes. Creating a report would mean combining a number of databases having different formats. Merging requires special database combining skills. So, compatibility between various databases by implementing new versions is the need of IT departments these days. So, many of the bigger companies in the corporate world were created thru data merging using different software and databases.

Thus in Java database connection, one would learn to manipulate certain files in order to develop query statements. One needs to keep in mind that they are represented by statements, prepared statements and callable statements procedure.

How FTP servers are hacked and get down

One of my friend Shadab Nawaz from Digitalpoint forum was very sad because he provides online e-services on his website but his FTP server have been brutally hacked and hackers moved his websites to PORN content and filled his home pages with nude models .By this he faced some huge losses in online business and some of my clients also moved . After facing this incident he decided to go in depth and know that how they do all this .

Shadab Nawaz from Magicsolv International share his tips in this article that how hackers do all this and how we can save ourselves . So the Prevention is better than cure .

A Password Cracker is a piece of software that attempts to break into a system by trying many different user names and passwords.

To break a password, a Password Cracker uses two methods of attack to break into your account.

1) Brute Force Attack: In this type of attack, the software generates passwords of every possible combination of words, letters, or even symbols to try to break into your account. The longer the password, the longer it takes to break into the system. However, since computers are gearing up the speed every year (according to Moore's law, the computer speed doubles every 18 months), the time to break a password of any certain length reduces 50% every 1.5 years.

2) Dictionary Attack: This is a more clever method in which the attacker uses a pool of words such as names, common vocabularies, etc., and tries various combinations of them to crack the system. The pool of effective possible choices to use in the trial and error process is much smaller than in a Brute Force Attack because of the more confined choices of numbers and letters to combine. It is very easy to get a word list. Do a search on Google for the search phrase "word list" to look for many databases available on the web.

now lets come to the point.......How to Remember Your Password

Coming up with a password which is both easy to remember and safe is no easy task. Try one or all of these different techniques to create a secure but memorable password.

Develop a Truly Random Password and Use a Mnemonic Device
(*) Use software or, less reliable but usually effective enough, simply jot down letters and numbers as they come to your mind.
(*) Focus on each letter of the password. A way to remember a randomized, assigned difficult password, like "tthertd" can be simple and fun. Think of a sentence where there is one word beginning with each letter of the password, for example, "tthertd" could be "terrible tigers have every right to drive."

Develop an Algorithm
(*) Take the name of the website and then add the last four digits of a friend's home phone number to the end. (Don't use your own phone number, since a clever hacker could try the same algorithm in a dictionary attack.) The password for wikiHow might be "wikiHow4588". This is by way of example only because it is too easy for others to figure out but you would add your own personal twist. Maybe you would spell wikihow backwards. The more steps in your algorithm, and the more unpredictable each step is, the more secure your password.

Combine the Best of You
(*) Choose a favorite number (or two), a favorite word (or two), a favorite symbol (or two). Add the first one (or two) symbols that come to mind when you see the website address or the most prominent words on the sign-in page. Choose an order and put them all together into one long string.

Remove the Vowels
(*) Take a word or phrase and remove the vowels from it (for example, "eat the cheeseburger" becomes "tthchsbrgr").

Use the Keyboard
(*) If your password doesn't use the Q, A, or Z, you can hit the key to the left of your password. Or to the right if you don't use the P, L, or M. 'Speedracer' goes to both sides, but 'wikiHow' can become 'qujugiq' or 'eolojpe'. Shifting things up a key, choose left or right. 'wikiHow' becomes '28i8y92' or '39o9u03'. Shifting up and to the left is slightly more intuitive. Adding the other security measures afterwards is all trivial.

Combine Small Words
(*) Combine. A smart way to develop an easy to remember password is to combine three small words to make a single password. For example, you can use "howstopyes" or "earpengold". If you want an even easier to remember password, you can use words that are related to each other like "yesnomaybe". Be aware, however, that this is much less secure! It adds more security to capitalize the first letters of the different words: "ballzonecart" becomes "BallZoneCart".

Connect the first letters
(*) Develop a password using the first letters of a sentence or phrase that means something to you - like your national anthem or a slogan you have seen somewhere. 'Don't shop for it, Argos it' would become DsfiAi.

Use a Password Manager
(*) Use a password manager, such as "PasswordSafe", "Roboform" or "PassPack" to generate random passwords and then secure them using one master password.

Mix Words
(*) Choose two words and combine their letters to create the password, choosing one letter of the first word and one letter of the second word, and repeating this until you get to the last letter of each word. An example could be:
Words: house & plane
Password: hpoluasnee

Some other tips too.............. i found them on the web....

(*) Change numbers into Roman numerals for more security (i.e. iamcool2 becomes iamcoolii). You can even mix normal numbers and Roman numerals. 1i = 11; 1ii = 12; and so on.

(*)When coming up with a mnemonic sentence, try and make the sentence funny or relevant to yourself. That way you will find it easier to remember the sentence, so you can remember the password.

(*)The more complex and longer the password, the less likely it is to be cracked but it is often proportionately harder to remember.

(*)Mixing letters and numbers is always safer than just using numbers or just using letters.

(*)Try thinking of a name (BOB). Now use only every second letter, being BB. Then go back and plug any other letter you did not type. Your password would be BBO.

Enjoy, and if you have other innovative ways to remember difficult passwords, let me know.
