SQL Injection

SQL Injection is a web attack mechanism used by hackers to gain access to the unauthorized databases and other content. It can be commonly described as the application layer attack.

Reason Behind the attack

The main reason behind SQL injection is improper coding techniques employed in development. This sort of improper coding gives a way for hackers to inject the malicious SQL command that in turn fetches the required unauthorized content to the hackers.

What skills required for a hacker?

Mostly hackers perform few simple attacks by just having basic knowledge with web browsers, SQL, creative guesswork to find table and field names

Where it starts?

Most hackers start injecting the malicious SQL commands in  Login Pages or in Support and Product request forms easily

Why Login pages act as the best place to start hacking?

Basically, SQL injection starts from login pages. During the login process, the user types the credentials (i.e. username and password) which is matched against the content that exists in the database. Hackers use this communication gap. They bypass access by interrupting this communication. They inject their content into DB and use this as a channel to steal the data. By worst case, the content becomes readable and get exposed to the hackers.

What technologies are used by hackers?

Hackers mostly use dynamic scripting languages like ASP.Net, PHP and Javascript.

SQL injection affects relational databases like MySQL,Oracle,Microsoft Access,MS SQL Server ,etc..

SQL injections fall into categories like First Order Attack and  Second-Order Attack

First Order Attack:

In this method, the hacker attack some strings to the input field and gains the response immediately

Second-Order Attack:

In this method, the hacker enters the malicious code into the database table and later access it with a third party ie another activity

Tips to prevent SQL injection attacks

1.       Strong server-side validation is recommended

2.       The stored procedure may prevent some sort of attacks

3.       Patches can be used

4.       Never allow the special characters in the user inputs

5.       Minimize the usage of executable SQL commands in SQL server

SEO Copywriting

SEO COPYWRITING:

Effective SEO Copywriting should give a clear view of the idea flashed  in your mind. It can improve the link building. ” Who what why” can act as the popular keywords. Using Numbers also will attract some users. For example,” Top 10 Programming Sites”

Effective quotes can gain some impact.

General Tips:

Interlink your articles and Have useful external links for better performance.

Also I have mentioned the other tips that I came across!

Present the content well: 

If the search engine comes across the similar words again and again, then it will consider your content as spam .So be aware of it and present the content well.

Keyword density 

Keyword density is a probability of keyword or a keyword phrase, in proportion with other words, appears on a Web page. Overall keyword density increases with the increase in the usage of keywords. The more times that other words appear, the lower the possibility of keywords, thus it leads to lighter keyword density

Font

The italic words are considered as the keywords by the search engine.So notify the search engine with the italic words .

META tags 

Google will get impressed if the TITLE and DESCRIPTION tags are similar or identical.

Numbered lists 

Try to use numbered content to get listed first . For example “10 easy tips to optimize the site “.This will maximize your output .

File names 

File names with keywords will be an added advantage.

Search Engine and Directory Submission

Directory submission is one of the very simple and must one to do to reach the target audience . For example, try  http://freewebsubmission.com/

Keyword stemming

keyword stemming is a a very useful tool in the world of SEO.The process of keyword stemming involves adding a prefix, suffix, or plurals to make the popular keyword into a new word.This is one of the main process that helps in increasing the website trafiic. 

Keyword Tool For SEO

There the keyword  related to our site should be entered and searching should be done. By using this, we can find the competition for that particular keyword. Also the competition, global monthly searches of related keyword will be displayed that gives a brief idea.

So this will be a right place to begin the keyword researchVARIOUS STEPS IN KEYWORD ANALYSIS

This step is most important and probably the easiest one and you can complete it in 3 simple steps without any additional software or paid programs offered on the market.

1] Making Analysis with people:

1. Use your network of friends and relatives to know, what phrases or words they use during their search and keep them in a list

SEO : Keyword Analysis

Keywords, as the name signifies they are the key items that are going to promote your site in the list made by the search engines. We can define a keyword as a single word or a combination of two or three phrases.. keyword analysis is the term or name given for the research made to find , what exactly the customers are looking for or typing during their search and what exactly he have to use to catch their attention or search engines attention.

Keyword discovery tools

Search marketing efforts can be greatly improved by the usage of Keyword discovery tools but they are bit costly to use.

Analyzing keywords allows you to:

Optimize Spend: Distribute budget based on the worth of the word used ie spend more on the words that fetch more benefits and spend low on the words that fetch you no use.

Increase Conversions: Always keep conversion rate optimization and return on investment (ROI) on mind

Eye Trends: Keep an eye on the current marketing trends and keywords

Prioritize Your Time: Prioritize areas that you have to concentrate more to keep yourself alive in the market.

Find New Markets: Use keyword analysis to grow your business and keep looking fr the breaking trends

Why Keyword Analysis ?

1) Targeting right audience

2) Getting lots of relevant traffic

3) Focusing on targeting geographic location

4) URL and Title Tag

Google focuses straight on the domain name and title tag to rank your site. The first and most important part of your on-page SEO is the title tag (<title></title>). You can find the title tag at the  top left of your page, where name and description will be given. Many people who outsource a site in a WYSIWYG editor completely forget about the last of the meta tags that still gives some quality ranking love from search engines.

A website's title tags are very important for several reasons:

1) The title tag shows up in search results as the blue link, and a good one helps the site get more clicks and visitors from search results.

2) Title tags are a crucial SEO element that can help the website show up higher when people search for the words in it.

3) Title tags show up when web pages are shared on social media sites like Facebook. This is important because social media mentions are now a ranking factor in Google search results.

The Things not to be done while framing title tags:

The term Home Page does not shower you any type of ranking so better avoid them in the title tags

Domain name can add significance to the site search ,which can be displayed during the listing

Though the title tag plays a significant role, length of the keyword is also the important factor. Search engines display only the first 70 characters of a web page's title tag and rest of the tag words are discarded. Also a short tag cannot turn the attention of the people so it’s better to choose the

Too many keywords will never help you in achieving the top list. Search engine will consider it as spam if too many keywords are added.

SEO Recommendations

Anyone who blindly using Search Engine Optimization techniques will not fetch fruitful results as expected.Sometimes, the search engines may find it as a spamming, though you did it genuinely.

2) We can submit our links via blog or mail to a list. We can submit our directories at various sites and that may gain us the attention of users or at least convince them to move towards us.

3) Getting reviews from users and listing them in our page will not produce us, very great results but still we can expect it to have little impact.

How I Start Writing About Search Engine Optimization !

Just today, when I was digging my Materials folder in my desktop, I found lots of stuffs that I dumped under the topic SEO .Yes, Its Search Engine Optimization. I was working as a intern during my last summer for a company and I was assigned the task to analyse various stuffs about Search Engine Optimization. 

Earlier I found it boring, But later I found the real worth behind this task of Search Engine Optimization (Popularly called as SEO) . So I made documentations with some sort of interest and started learning the SEO. 

Just after a minute of having the history flashed in my mind, I thought of sharing all the stuffs I prepared during my internship to all the readers here.

For some time, I will publish the materials that I prepared from various sources here and feel free to post your comments as I crossed a long way in the domain of SEO and I hope I can help you out at least to some extent if some sort of help required!

Optimizing the site to get listed at the top during the search you made through various search engines like Google, Yahoo, Bing, etc.  is an art and business of course (If I am not wrong) .How can a site opened few months back can impress millions of viewers everyday ? I can guess your answer. Yes many of you will say me the answer “By providing some quality content “. Yes, Of course you are right. But what if , millions of sites getting registered every day comes up with a quality content  . Here the issue emerges! The competition arises between the quality sites that holds equally quality content. There comes the Savior Search Engine Optimization .

Search Engine Optimization is the technique that helps Google in finding the right site to get listed at the top. Various sub topics exist inside Search Engine Optimization which should be mastered before you start optimizing the site.

Starting from keyword analysis to the use of Google analytics tool, lots of process involved in optimizing a site. I have made few articles that may help you in your mission of optimizing the site .

Happy Journey with SEO ! 

Search Engine Optimization : Part 1

You may own a fantastic site regarding shopping, mobile reviews, marketing, blogging, etc.. But why your site is not getting displayed at the top during google search? Have you ever wondered of it? Does it have some logic behind?

Yes Of Course!! Many reasons are behind it! Google will never display some content at the top without having some sort of logic! It’s not only about your content, popularity, length  or period of existence !!   

The main reason, why few sites are displayed on the top of the google search is Search Engine Optimization! If you want a brief intro check my previous article!

In this article, I have discussed about the tools used in search engine optimization. I remember, I made this article long back for my internship purpose and just thought of sharing with you all!

The first and foremost tool to be employed in optimization is Google Insights for Search . It’s very necessary to analyze the keywords involved in the Google ranking. By using the appropriate keyword, we can increase the site ranking .Also, it’s very important to analyze the speed of our site so that we can enhance the speed after spotting the missing term. For this purpose, we can employ Google web master tool that checks the website speed.

The websites are recognized by the users based on their visibility in the first page. So every site tries to list their names in the top of the opening page. The text that exists in the hyperlink can be exactly tracked and the number of keywords can be increased. The keywords expected by the search engine should be initially analyzed and used properly. It’s important to find the related sites and we can make a comparison to put our site on top of the list. Web Master Tool may be helpful in achieving this.

So start with web master tool and Google analytics tool. Then, try comparing the existing keywords of the site with the required keywords to be added. Also the speed of the site can be analyzed to enhance the performance.

The context representing our site should be of high worth and it should be able to impress the attention. Regular monitoring of broken links should be done. The troubles made by the Search engine spiders should be overcome. The web server should be well designed to report the modification to the Google. The googlebot crawlers should be under consideration.

Also the site should be tested under different search engines. It was recommended not to use the unauthorized sites to check the quality of the site and not to use the hidden words.

How Google Works ?

Basically, Google includes three main parts that includes a Google Bot, indexer and a query processor. Google bots, a search engine spider retrieves thousands  of pages simultaneously and provide the information to the indexer. It crawls over the web and search for the particular pages and it also considers the add URL form. The Google bots add the fetched pages into the queue of the indexer. But, these bots are in the need to overcome some spamming problems like duplicate contents, cloaking, hidden text, domain spam, hidden links, typo spams. Bots are programmed in a such a way to differentiate the automated codes.

The Google index database stores the datas collected by the bots. Alphabetically sorted index helps in easy retrieval. The task of the query processor is to evaluate the queries and matching the verified documents. After successful evaluation, the pages are ranked based on the position of pages in page rank data structure.

Scala :Setting Trend

Scala is a modern programming language that turned the attention of more programmers especially the java programmers. Scala is the acronym of scalable language. It can be listed under object oriented, functional as well as scripting language.

Its easy for the current java programmers to learn scala .Java libraries or existing application code written in java is completely reusable with scala. You can call scala from Java and you can call Java from scala, the integration is seamless.

Similarities between java and scala are many.Javac is the java compiler,While Scalac is the scala compiler .Both Java and Scala produces the Byte Code.Scala is also supported by most of the Java .IDEs like NetBeans,Eclipse,etc

When we code something with scala,we can expect to solve more errors during compile time rather than the deployment phase. Scala supports operator overloading which is not supported by Java.  LinkedIn,EDFT,Twitter,Novell,theGuardian,Xebia,Xerox,FourSquare,Sony,Siemens,Thatcham,GridGain,AppJet,Reaktor and many others  use scala in a wide phase and expected to dominate soon.

In Scala, Every value is an object and every operation is considered as a method call .It also provides backward compatibility with java where we can take advantage of using traditional design patterns . Also implicit calls add a beauty to the language ie it allows you to add new operations to the existing class .Recursive dependencies also supported here in scala .

We can define scala as the Java without semi colons  ie semi colon syntax error . Usually we use Value types initiating with small letters like int,double,Boolean but in scala the initial letters are capitalized like Int, Double, Boolean instead of int.Instead of Java's import foo.*;, Scala uses import foo._.

Scala has the following properties

1)Polymorphioc Methods

2) Generic Classses

3)Variance annotations

4)Upper and lower type bounds

5)Compound Types

6)Views

Hello World Program          

 object HelloWorld {

 def main(args:Array[String]){

println(“Hello World”)

}

Yes..! Scala is trend breaking . Most of the developers say,its gonna be the future of programming.Here ,a question arises in everyone’s mind.

Do scala Kill Java ?

Java 8, packed with productivity and trending features like  lambda expressions, methods, references, and functional interfaces is going to be available soon .  

And this question is interesting and even I have not started with scala. Lets wait and watch !

I will come up with a much more detailed article after having some hands-on coding with scala!!

E Waste

Introduction

E waste or electronic wastes refers to the electronic goods that are dumped out or discarded. Each year around 50 million ton of e-wastes are produced. Depending upon their nature of reaction , there are possibilities for dangers depending upon the situation. Discarded computers, batteries and other electro chemical wastes may results in unwanted results. So its important to be aware of e wastes in addition to the other physical wastes. This article sounds the fact of e waste management and recycling.  

Basel Action Network (BAN) estimates that the 500 million computers in the world contain 2.87 billion kgs of plastics, 716.7 million kgs of lead and 286,700 kgs of mercury. The average 14-inch monitor uses a tube that contains an estimated 2.5 to 4 kgs of lead. The lead can percolates into the ground water from landfills thereby contaminating it. If the tube is crushed and burned, it emits toxic fumes into the atmosphere.

Disposing e wastes by burning leads to major problems and it accounts a major part in air pollution. The unwanted chemicals produce the fumes that get mixed up with the air and it destroys the nature of the air. Sequentially, it attacks human during respiration. So the recycling should be done to use them efficiently again.

Causes for E Waste

Ø  Manufacture Technology of a Computer

Ø  Invasion of Technology

Manufacturing Technology of a Computer

To manufacture a computer 240 kg of fossil fuel, 22kg of chemicals and 1500kg of water are needed. Once the computers are thrown out they may leads to many serious problems. Burning of fossil fuels leads to global warming and green house effect occurs. Thus the temperature of the atmosphere is getting increased, just think off if 240 kg of fossil fuel burnt per computer. Carbon dioxide content is made maximum with the burning of fossil fuels. Carbon dioxide is one of the greenhouse gases that enhances radioactive forcing and contributes to global warming

Invasion of Technology

Nowadays we can find computers in everyone’s home. It is estimated that there are over a billion personal computers in the world at present. The computers are becoming cheap so no one is bothering about its maintenance. In developed countries, computers have the life span of 2 years.

E waste management tips:

Ø  Don’t throw the waste cell phones, dumped systems into the land fills. Properly, deliver them to the organizations where recycling is carried out.

Ø  Get the electronic goods from the vendors who can take back for recycling.

Ø  Take care of life time of your hardware equipments and so that  e waste can be efficiently decreased

Ø  Big Industries may buy recyclers that can used for long time.

Ø  Support green engineering.

Ø  Citizens should turn their interests to use the recycled products

Waste minimization in industries involves adopting following methods for efficient waste management:

Ø  inventory management,

Ø  production-process modification,

Ø  volume reduction,

Ø  Recovery and reuse.

Conclusion

This article is made just to give the awareness of e wastes .Its the duty of every citizen to take care of their own electronic equipments and to recycle them. With the invasion of technologies, life is becoming comfortable but the nature is getting highly degraded .So Green Technologies should be welcomed for future world.

Human Area Network :

Red Tacton:

Everybody wants to make the life simpler and thus scientists of NTT Labs are trying to develop a new trend HAN [Human Area Network] in addition to the LAN, WAN & MAN that makes the transmission of signal, much simpler  through the human body. This new type of Network is popularly known to be Red Tacton. Its commonly known fact that  human body generates negative charges but a new research proved that communication is possible by just handing  a Red Tacton touch device in our pockets. All physical movements like touching, gripping, sitting, walking, stepping and so on are used as triggers for various processes of this equipment. In Red Tacton device, the extent to which the optical properties of the body are changed is detected by laser light which is then converted to an electrical signal by a detector circuit that makes the communication possible. It has broad application in the daily life of human and expected speed is 10 MBPS. A study said that it will not affect human body and even the multiple communications will not affect the speed. It can be used efficiently by astronauts and physically disabled people to have an easy communication. In this paper, I have discussed the principle, working and suggested the working environments where the Red Tacton Technology has huge role to play.

Let me give a brief intro :

Communication plays an important role in our life. Our life will be simple if safe, secure and easy communication is possible. An efficient intra body communication system is developed to provide a very secure, fast communication by NTT Lab known to be RED TACTON. Red- Warmth, T- Touch, and Acton- Action stands for RED TACTON .If we could use the human body itself as a transmission medium, then this would be an ideal way of implementing human area networks because it would solve at a stroke all the problems including low security, throughput reduction, and high network setup costs.

Lot of technologies is emerging everyday and they are getting implemented in various fields to make our life more convenient. We are familiar with the networks like LAN (Local Area Network), WAN (Wide Area Network); MAN (MetroPolitian Network) but here is the new type of Human Area Network which is popularly known to be Red Tacton.NTT.

Lab located at Japan is currently designing this technology. Red Tacton relies upon the principle that the optical properties of an electro-optic crystal can vary according to the changes of a weak electric field. They can be efficiently used in security, medical field, and the device communication field

Red Tacton employs a proprietary electric field/photonics Method, which overtakes the other methods in terms of communication distance, transfer speed, and interactivity. It is highly secure and impossible to get hacked. It is a high speed network and well suited for short distance communication. In future , where man is destined to reach new heights of technology ,a trend like RedTacton is likely to direct him in the right direction giving him hope and motivation than any other technology man is able to perceives on the human centered interaction
