One of the very common error , students face day to day is

       "You do not have the permissions to upload file to the folder“

And as most of you aware that, chmod 777 <directory_name>  is the command that gives you permission to Read/Write/Execute the the content of the folder , this article is about the number 777. Yes, what does it mean by the number 777 in the chmod ?

Each folder will have an 8-bit data for granting permissions. By default, 000 means, no permission is available. By granting Read permission, 4 bits are added to the data. By providing Write permission, 2 bits are added to the data. By providing execute permission, 1 bit is added to the data. So totally it's 7.

Now, immediately follow-up question is why 777?

First digit 7 grants permission to the owner

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 : 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:

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.
