In the field of cyber security, there are two distinct groups of individuals, hackers and crackers. A person will ultimately be classified as either one or the other depending on their particular intentions; however there are different skill sets and subgroups typically associated with each title. To help differentiate, below is a breakdown of hackers, crackers and everything in between so you can gain a better idea of who is responsible when a cyber security breach occurs.
These experts in computer security tend to have non-malicious intentions and thus have become colloquially known as “white hat” hackers. White hat hackers engage in ethical hacking, which consists of lawfully breaking into systems for the purpose of exposing security flaws. They either seek to improve the protection of their own security systems or they are hired by organizations to perform this service. In order to do this, the hackers will initiate assessments of the company’s security system by attempting to penetrate it. If the hacker is successful during penetration tests, they are generally responsible for reporting the issue and developing a solution to prevent the same kind of security breach from occurring maliciously in the future. Companies often hire individuals to test for these vulnerabilities instead of leaving possible holes in their security systems open to attack by malicious hackers, commonly referred to as “crackers.”
Hackers often make the argument that crackers are less knowledgeable of computer systems and lack originality in their work, which is true to an extent. Crackers are motivated solely by personal gain and are not concerned with learning the ins and outs of computer systems as much as their counterparts. Additionally, the fact of the matter is that crackers do not need to follow ethical guidelines; they simply need to exploit the system. The primary goal of a cracker is either to obtain valuable information that will lead to personal gain or to cause mischief for organizations simply because they are capable of it. Regardless of their motives, the malicious intention of these crackers has led to them being labeled as computer criminals, or “black hat” hackers. They may choose their victims randomly or target specific organizations based on profitability and other interests, but the end goal is always for their personal gain never as an ethical profession. These crackers are often caught for their malicious acts because they are not cautious or mindful of the protections that have been put in place by a business’ white hat hackers. Businesses with secure networks will hire ethical hackers to establish a honeypot, which is essentially a trap used to detect and counteract unauthorized breaches by the black hat community.
Hackers:
The term “hacker” typically refers to individuals who seek to fully understand how computers and network systems function in order to gain in-depth knowledge and perform a precise exploit of vulnerabilities.These experts in computer security tend to have non-malicious intentions and thus have become colloquially known as “white hat” hackers.

Companies often hire individuals to test for these vulnerabilities instead of leaving possible holes in their security systems open to attack by malicious hackers, commonly referred to as “crackers.”
Crackers:
The title of a “cracker” has gained much controversy over the past few years in regards to its malicious connotation and the reputation these individuals have gained throughout the cyber security community.Hackers often make the argument that crackers are less knowledgeable of computer systems and lack originality in their work, which is true to an extent. Crackers are motivated solely by personal gain and are not concerned with learning the ins and outs of computer systems as much as their counterparts. Additionally, the fact of the matter is that crackers do not need to follow ethical guidelines; they simply need to exploit the system. The primary goal of a cracker is either to obtain valuable information that will lead to personal gain or to cause mischief for organizations simply because they are capable of it.

Businesses with secure networks will hire ethical hackers to establish a honeypot, which is essentially a trap used to detect and counteract unauthorized breaches by the black hat community.
Grey Hat Hacking:
The term “grey hat” is used as a combination of white hat and black hat because it refers to hackers that engage in both hacking and cracking. While they may break into computer systems for the purpose of making a profit, their intentions are not entirely malicious. The grey hat hacker may have to perform illegal actions in order to test a system for vulnerabilities and make the necessary improvements. A possible scenario for a grey hat hacker could be breaching the security system of a company and then notifying them of the vulnerability in hopes of receiving a payment to improve the system. These tactics are seen as questionable in the hacking community, but in the end they result in a positive outcome for the hacker and improved security measures for the involved organization.Author Bio:

For all the developers who have expressed interest in getting programmatic access to the search queries data for their sites in Webmaster Tools, we've got some good news. You can now get access to your search queries data in CSV format using a open source Python script from the webmaster-tools-downloads project. Search queries data is not currently available via the Webmaster Tools API, which has been a common API user request that we're considering for the next API update. For those of you who need access to search queries data right now, let's look at an example of how the search queries downloader Python script can be used to download your search queries data and upload it to a Google Spreadsheet in Google Docs.
Example usage of the search queries downloader Python script
1) If Python is not already installed on your machine, download and install Python.
2) Download and install the Google Data APIs Python Client Library.
3) Create a folder and add the downloader.py script to the newly created folder.
4) Copy the example-create-spreadsheet.py script to the same folder as downloader.py and edit it to replace the example values for “website,” “email” and “password” with valid values for your Webmaster Tools verified site.
5) Open a Terminal window and run the example-create-spreadsheet.py script by entering "python example-create-spreadsheet.py" at the Terminal window command line:
If you just want to download your search queries data in a .csv file without uploading the data to a Google spreadsheet use example-simple-download.py instead of example-create-spreadsheet.py in the example above.
You could easily configure these scripts to be run daily or monthly to archive and view your search queries data across larger date ranges than the current one month of data that is available in Webmaster Tools, for example, by setting up a cron job or using Windows Task Scheduler.
An important point to note is that this script example includes user name and password credentials within the script itself. If you plan to run this in a production environment you should follow security best practices like using encrypted user credentials retrieved from a secure data storage source. The script itself uses HTTPS to communicate with the API to protect these credentials.
Take a look at the search queries downloader script and start using search queries data in your own scripts or tools. Let us know if you have questions or feedback in the Webmaster Help Forum.

salam every one, this is a topic from google web master centrale blog: Webmaster level: Beginner
Cross-posted on the Google Grants Blog
In our previous post, we did some source code housekeeping -- just in time for the holidays. But once users have landed on your site, how can you make sure they’ll know how to get around?
As it turns out, easily accessible content on your site can make a big difference. Users tend to have a better experience when a site helps them find and understand its content. Having an accessible site not only empowers users, it also helps search engines understand what your site is really about.
So if you’ve resolved to boost your site’s user experience and online presence for the new year, improving your content accessibility is a great way to start. Thankfully, there are tons of features you can add to make your site more accessible. In this post, we’ll highlight three of them:
- Intuitive navigation
- Concise, descriptive anchor text for links
- Unique, accurate page titles throughout the site
Intuitive navigation
Help users avoid confusion by providing them with intuitive navigation, so that when they arrive at your site, they’ll know where to click to find the information they’re looking for.
Here are three features you can implement in order to lead your users down the right path:
- Navigational menu: Having a menu with links to the site’s most important pages is the fastest, easiest way to show users where to click next.
- Text-based links: While drop-down menus, image-based links, and animation-based links can be appealing, keep in mind that users on text-only devices and some search engines may not be able to see or understand these links. Thus, many users prefer text-based links, which are also easier for search engines to crawl and interpret.
- User-viewable site map: 59% of our submissions did not have a user-viewable site map. By providing one, you display the structure of your site and give the user easy one-click navigation. If users are having trouble finding specific pages on your site, a site map can help them find their way. Don’t send your users into the wild without a map!
Let’s explore how these features can make a site’s navigation more intuitive by looking at one of our submitted sites, Philanthropedia.
Thanks to this site’s clean navigational menu, users can find all of the site’s important pages within a few clicks. Wherever users end up on the site, they can always click on the “Home” button to return to the main page, or on any of the links in the menu to return to the site’s important subpages. Like all of the links on this site, the links in the navigational menu are text-based links, which make it easier for both search engines and users to access the site’s content. Finally, Philanthropedia has included a user-viewable site map, shown below, in case visitors are looking for a specific page not listed in the main menu.
Concise, descriptive anchor text for links
Anchor text -- the clickable text of a link -- can help users quickly decide which links they want to click on and find out more about. Meaningful anchor text makes it easier for users to navigate around your site and also helps search engines understand what the link’s destination page is about.
20% of our submissions could improve their sites by improving the anchor text used in some of their internal links. When writing anchor text, keep two things in mind:
- Be descriptive: Use words that are relevant to the destination page, avoiding generic phrases like “click here” or “article.” Make sure the user can get a snapshot of the destination page’s overall content and functionality by reading the anchor text.
- Keep it concise: Anchor text that contains a few words or a short phrase is more attractive and convenient for users to read than a sentence or paragraph-long link.
Let’s take a look at how anchor text played out in two user-submitted examples:
| Organization | Anchor Text Examples | User Friendliness | Anchor Text Behavior |
| The Mosaic Project | Work for Mosaic Order Our Curriculum Guide Outdoor School | High: Users can get an accurate idea of the content on the links’ destination pages just by reading the anchor text. | Active verb phrases and rich nouns accurately describe the pages that the links are pointing to. |
| Asian Liver Center | Learn more here | Low: The anchor text is too generic and does not give users an idea of what the linked-to content is. | Generic phrases give little insight into the pages that the links are pointing to. |
You can learn more about anchor text and internal linking strategies by checking out this blog post on the importance of link architecture.
Unique, accurate page titles throughout the site
Each page on your site is different, so flaunt your site’s diversity by giving a unique title to each page. Giving each page a unique title lets search engines know how that page is distinct from others within your site. In our analysis, over 28% of sites could have improved their site quality by adding unique page titles.
Let’s check out a few more examples to see what a difference unique, accurate page titles can make:
| Organization | Page Title Examples | User Friendliness | Page Title Behavior |
| VAMS International | Upcoming Events | VAMS International Request Service | VAMS International FAQ’s | VAMS International | High: Each page’s content is relevant to its title, and the user can get a good idea of each page’s unique offerings and functionality. | Concise, rich language joined with the organization’s name accurately describes the corresponding pages. The titles show how each page is unique while also acknowledging that they are all associated with one organization. |
| MHCD Evaluation and Research | MHCD Evaluation and Research | Low: This site contains a lot of diverse content and rich functionality; however, the uniform page titles do not convey these strengths. | This page title is too general and does not accurately describe the content on each page. The same title is used across all the pages on this site. |
Wrapping things up
We hope that this blog post has given you some ideas on how to ring in the new year with improved content accessibility, which can boost the user experience and online presence for your site.
To learn more about the features discussed here and in our previous two site clinic posts, check out our SEO Report Card and SEO Starter Guide.
This blog post wraps up our website clinic for non-profits. We send our warmest regards to all the great non-profit causes you are working on, and thanks to everyone who took the time to submit their sites and read our posts!
