How to hack the network Server

How to hack the network Server

In our first hacking preparing session we had learn how to prepare for a Hack such as what are the language skills are required, how to select the tools and targets. In this session we are going to look how to things you should take care while and after hacking a target. Here we are going to look How to hack the network Server, how to hack a network computer, How to get into the target, how to gain access, how crate backdoor and how to clear the tracks are the topics in this session.

1) Secure yourself.

Before you start the hack you should make sure you are not going to race back.  Meantime you must make sure that you have understood all techniques to make safe yourself.

If you are going to attack the target or network with permission as a White Hat Hacker, you should get the permission in writing. This will help you that you are a authorize person to attack and check the security level.  When it’s a white hat hack make sure you are not using any illegal or crack software,  in a commercial environment this type of software are put you in trouble.

But if you are a Black Hat hacker no matter what are you going to use and what will be the impact of the attack. Before start the attack. If you use the VPNs you can make sure you are in safe.

2) Analysis the objective.

When you are ready to attack the system you or network you can use the ping command to check the availability of the network.  When you get the positive reply mean the target is active and live. But the result cannot be trusted all times. Because some the Administrator can shut or disable the ICMP reply facility.

3) Use terminal for commands.

 There are several command line terminals are available and most of them are open source. You can download and use those without any problem. Nmap, Cygwin,WinPCap are some. Cygwin will support for windows users also. But Nmap useWinPCap to runs on Windows.You can use Linux or BSD which are more flexible and most of them are with may preinstalled useful tools

4) Identify the OS.

Before start the attack you must identify the target and Os. You can scan the ports using nmap and select the open ports.  When you got in to the open port you can open the machine and get the details of the OS using the nmap tool with –O, after that you can easily get the details of switch and it will give all the details of the Firewall and routers they are using and you can plan an action.

5) Locate an open port.

Usually the ports which are using frequently such as HTTP (80), FTP (21) well protected by the System Admin and keep those ports are locked.  But hackers use take advantage on the other ports to get into the system. Try other TCP, UDP ports those are forgotten by most. Telnet or UPD ports which are using for LAN gaming and sometimes left open

6) Crack the authentication process.

We can crack the passwords in several ways such as bruteforce or Dictionary attack.  When you select the bruteforce attack on a site or system the password is an effort to try every possible password contained in the dictionary.

But when you use the bruteforce attack you must consider that the systems encourage the users to use a hard password. So it will take time to crack the passwords. Most of the hashing algorithm is weak you can improve the cracking speed to cut thas in segments. If the MD5 has you can cut pieces you increase the speed.

Some tools are using GPU (Graphic Processor) which is thousand time faster than the normal system processor.

 7) Get the super-user privileges.

Once you got into the system always try to get root privilege (Super Admin) when if it’s a Linux machine target *nix or Windows get the access of Administrator. Most of the information that will be of critical curiosity is sheltered and you need a certain level of authentication to get that. if you want to see all the important files on a system attacker must need super-user privileges.

8) Use diverse tricks to get The Super user account.

Hacker use several tactics to gain the super user access like creating Buffer Overflow, which cause the  memory to dumb and that allow the attacker to inject the code or perform a task at a higher level than you’re normally authorized.

9) Create a backdoor.

When attacker succeeded to hack and get the access of full control over the system, must make sure that come back again without any delay or problem. It can be done through a backdoor. Sometimes it may be removed when the system admin upgrade the services. But a well experienced hacker can make the backdoor compile itself

10) Cover your tracks.

After finishing all the JOBs you must make sure that the administrator won’t get alarm on that the system is compromised. For that don’t change any single thing in the target to don’t produce any unnecessary additional file or users in the target act as quick as possible. Once you pack the server with SSHD or other way you must make sure the secret password is encrypted and hardcoded and when any one tries to login using the password system should let them in but not contain any sensitive information.

SEO - Content is the King

Content basically includes what you see on the site: the text, graphics, and even links to other websites. You should not use excessive graphics because they are not Search Engine Friendly plus heavy graphics normally put the users out when they get downloaded, especially over a slow network.

Thousands of articles, books, and forum entries are available on how to make your website search engine friendly, but ultimately, one rule stands above the rest: Unique, high-quality, unduplicated content is the king.

Superior the quality of your content, the higher the ranking you achieve, larger the traffic you gain and greater the popularity of your website. Search engines prefer good quality sites in their index and search results.

Relevant, fresh, and timely content is crucial in attracting visitors to your website. It helps you both draw traffic from search engines and create audience loyalty.

Unique, High-Quality Content

When people visit a website for information, they want your unique spin on a topic. How is your material or content unique? Is that uniqueness obvious, and easy to find and to understand? Visitors want unique, high-quality site content. It is not only your home page content, but also all the linked pages should have useful and easy-to-understand content.

Now-a-days, search engines have become very smart and they are able to understand complete grammar and complete phrase. Hence while ranking a page against other, the content available on a page matters.

Sites with duplicated, syndicated, or free content are get given red flags by the search engines.

SEO Content Writing (Copy Writing)

SEO Content Writing (also referred as SEO Copy writing), involves the process of integrating keywords and informative phrases which make up the actual content of your website.

While writing your webpage content, the following tips may help you in keeping it better than others.

• The content should be directed for the specified target audience.
• Keyword density is strictly adhered as per search engine guidelines.
• Titles should always be eye-catching, compelling your visitors to read on and want to know what you offer in your website.
• Do not use confusing, ambiguous, and complex language. Use small statements to make your content more understandable.
• Keep your web pages short.
• Organize and distribute the content on the webpages.
• Divide your web page content also into short paragraphs.

Other Advantages of Having Great Content

It is not only SEO you need to think about. Many factors contribute to make your site popular.

• If your site is having something really unique, then people like to suggest it to their friends.
• Other webmasters like to create a link of your site on their sites.
• Your site visitors start trusting on your site and they look forward for the next content update and keep coming again and again.
• Although you are listed out by search engine, a but net surfer will click only that page whose content snippet looks more unique and interesting.

Conclusion

Creating, editing, and promoting unique high-quality content is difficult and time consuming. But in the end, the golden rule of SEO is that Content is the King. It is not because of a search engine, but it is for your site visitors. A page that is read by people is better than a page that is read by bots.

So, write your content after a serious thought. Keep your title, keywords, link text, metatags up-to-date, unique, and interesting.

SEO - Optimized Anchor

Use descriptive anchor text for all your text links. Most search engines consider anchor text of incoming links when ranking pages. Here is an example of anchor:

 href="otherpage.htm" title="Anchor Title">Anchor Text

Listed below are some of the important points to note about anchors:

• The Anchor Title plays a very important role and is seen by most of the search engines. The anchor title should have appropriate keywords. Anchor title helps the site visitors using a balloon, and displaying written text.
• The Anchor Text is another important part, which should be selected very carefully because this text is used not only for search engines but also for navigation purpose. You should try to use the best keywords in your anchor text.
• The otherpage.htm is the link to another webpage. This link could be to an external site. Here, you need to ensure that the linked page does exist; otherwise it is called a broken link, which gives a bad impression to search engines as well as to site visitors.

Another example of an anchor could be as follows:

 href="otherpage.htm" title="Anchor Title">
    src="image.gif" alt="keywords" />

In this case, Anchor Text has been replaced by an image. So, while using an image in place of an anchor text, it should be checked that you have put alt tag properly. An image alt tag should have appropriate keywords.

SEO - Title Optimization

An HTML TITLE tag is put inside the head tag. The page title (not to be confused with the heading for a page) is what is displayed in the title bar of your browser window, and is also what is displayed when you bookmark a page or add it to your browser Favorites.

This is the one place on a webpage where your keywords MUST be present. Correct use of keywords in the title of every page of your website is extremely important to Google - particularly for the homepage. If you do nothing else to optimize your site, remember to do this!

Here are some considerations while designing the title of a webpage:

• The title shouldn't consist of more than about 9 words or 60 characters.
• Use keywords at the very beginning of the title.
• Do not include your company name in the title unless your company name is very well known.

Improper or nonexistent use of titles in webpages keeps more websites out of top rankings on Google than any other factor except perhaps for a lack of relevant content on a page or a lack of quality links from other websites that point to your site.

Best Practices for Creating Titles

Here are some best practices you should follow for creating titles on pages:

• Each page should have a unique title.
• If practical, try to include your Primary Keyword Phrase in every title of every page.
• Begin the title of your home page with your Primary Keyword Phrase, followed by your best Secondary Keyword Phrases.
• Use more specific variations to your Primary Keyword Phrase on your specific product, service, or content pages.
• If you must include your company name, put it at the end of the title.
• Use the best form, plural or singular, for your keywords based on what WordTracker says is searched on more often.
• Do not overdo it - do not repeat your keywords more than 2 to 3 times in the title.
• Make sure the

SEO - Optimized Metatags

There are two important meta tags:

• Meta description tags
• Meta keyword tags

Some search engines may display the meta description as a part of the search results, but the meta keyword tags should not appear in search results.

The general consensus among SEO experts is that metatags are dead. Even so, many of these same experts continue to use metatags in their own sites.

For Google, adding the description meta tag does not result in a boost in the Search Engine Results Pages (SERPs), but the description might be used for the description for your SERP listings in Google.

Yahoo! says, they use the Keyword Meta Tag when it ranks a page. Hence it makes sense to add one for Yahoo! and any other minor search engines that still use.

What Do the Metatags Look Like?

You can add the following in the head section of the web page:

 name="keywords" 
         content="KEYWORD1 KEYWORD2 KEYPHRASE1 etc. 
         about 30 to 40 unique words">

 name="description" 
         content="An accurate, keyword-rich description 
         about 150 characters">

Meta Description Tag Tips

Important tips for good Meta description tags:

• Use keywords in your meta description tag.
• Try not to repeat the words overly often, but try to use multiple syntaxes of your key words.
• There should not be more than 150 characters in a description metatag of a single web page.
• Use a different meta description tag for each page, as each page is different and stands a better chance of being found if you place a good title and description on it.

Meta Keywords Tag Tips

Please refer to the previous chapter for identifying good keywords. Use the following tips for preparing good meta keywords tags.

• Use synonyms.
• Use unique keywords.
• No need to repeat any given phrase.
• You can repeat a word any number of time, as long as each time it is part of a different phrase.

Robots Meta Tag

The important metatag that you may need sometime is the Robots Metatag which looks like this:

 name="robots" content="noindex,nofollow">

Using the above metatag, you can tell a spider or a robot that you do not want some of your pages indexed, or that you do not want your links followed.

SEO - Optimized Keywords

A keyword is a term that is used to match with the query a person enters into a search engine to find specific information. Most people enter search phrases that consist of two to five words. Such phrases may be called search phrases, keyword phrases, query phrases, or just keywords. Good keyword phrases are specific and descriptive.

The following concepts related to keywords, help in optimizing the keywords on a web page.

Keyword Frequency

This is calculated as how often does a keyword appear in a website title or description. You do not want to go overboard with frequency, however, since on some engines if you repeat a word too many times, you are be penalized for "spamming" or keyword stuffing.

In general though, repeat your keyword in the document as many times as you can get away with, and up to 3-7 times in your list of metatags.

Keyword Weight

It refers to the number of keywords appearing on your web page compared to the total number of words appearing on that same page. Some search engines consider this while determining the rank of your website for a particular keyword search.

One technique that often works well is to create some smaller pages, generally just a paragraph long that emphasizes a particular keyword. By keeping the overall number of words to a minimum, you can increase the "weight" of the keyword you are emphasizing.

Keyword Proximity

It refers to the placement of keywords on a web page in relation to each other or, in some cases, in relation to other words with a similar meaning as the queried keyword.

For search engines, that grade a keyword match by keyword proximity, the connected phrase home loans will outrank a citation that mentions home mortgage loans assuming that you are searching only for the phrase "home loans".

Keyword Prominence

It is a measure of how early or high up on a page, the keywords are found. Having keywords in the first heading and in the first paragraph (first 20 words or so) on a page are best.

Keyword Placement

Where your keywords are placed on a page is very important. For example, in most engines, placing the keywords in the Title of the page, or in the Heading tags will give it more relevancy. On some engines, placing keywords in the link text, the part that is underlined on the screen in a browser, can add more relevancy to those words.

Best Places to Put Keywords

Here is a list of places where you should try to use your main keywords.

• Keywords in the

SEO - Design & Layout

The website design and layout gives the first impression about your site. There are sites which are too fancy and regular net surfers just reach those sites and come out even without creating a single click.

Search engines are very smart but after all, they are software and not human being, who can read the content of their interest. If you make your site too complicated, then the search engine would not be able to parse the content of your site properly, and finally indexing would not be efficient, which results in a low rank.

The actual page content should have a keyword density of about 10% and should weigh in at about 200 words - but there are as many opinions about this as there are SEO experts. Some say, keyword density should be 5% and some say it should be 20%. You can go with 10% which is good enough.

Here are a few guidelines that you should keep in mind while designing a web page.

• You should have more text content than HTML elements.
• No frames. They are the enemies of search engines, and search engines are enemies of frames.
• No ads if possible. Because most of the ads use Java-Script which is not advised to be used.
• No JavaScript. If you need JavaScript, call it from an external file rather than dumping the code in the HTML file. JavaScript drop-down menus prevent spiders from crawling beyond your homepage. If you use them, be sure to include text links at the bottom of the page.
• Do not put anything in the page topic that does not fit perfectly.
• No unnecessary directories. Keep your files as close to the root as possible.
• No fancy stuff (Flash, Splash, Animated Gifs, Rollovers, etc.) unless absolutely necessary.

SEO - Relevant Filenames

One of the simplest methods to improve your search engine optimization is to look at the way you name your files. Before writing this tutorial, we did a lot of research on file-names and found that search engines like Google give too much importance to file names. You should think what you want put in your web page and then give a relevant file name to this page.

Just try giving any keyword in Google search engine and you will find file names highlighted with the keyword you have given. It proves that your file name should have appropriate keywords.

File Naming Style

• The filename should preferably be short and descriptive.
• It is always good to use same keywords in a filename as well as in page title.
• Do not use filenames such as service.htm or job.htm as they are generic. Use actual service name in your file name such as computer-repairing.htm.
• Do not use more than 3-4 words in file names.
• Separate the keywords with hyphens rather than underscores.
• Try to use 2 keywords if possible.

File Name Example

Listed below are some filenames which would be ideal from the users' point of view as well as SEO.

slazenger-brand-balls.html
wimbledon-brand-balls.html
wilson-brand-balls.html

Notice that the keywords are separated by hyphens rather than underscores. Google sees good filenames as follows:

seo-relevant-filename as seo relevant filename(good)

Filenames with underscores are not a good option.

seo_relevant_filename as seorelevantfilename (not good)

File Extension

You should notice that .html, .htm, .php and any other extension do NOTHING for your visitors, and they are simply a means of offloading some of the work of configuring your webserver properly onto your visitor's. In effect, you are asking your site visitors to tell your webserver HOW to produce the page, not which one?

Many Web masters think that it is a good idea to use filename without using extension. It may help you, but not a whole lot.

URL Sub-Directory Name

From Search Engine Optimization point of view, URL sub-directory name hardly matters. You can try giving any keyword in any search, and you will not find any sub-directory name matching with your keywords. But from the user's point of view, you should keep an abbreviated sub-directory name.

Guru Mantra

Keep the following points in mind before naming your files:

• Keep the web page filename short, simple, descriptive, and relevant to the page content.
• Try to use a maximum of 3-4 keywords in your filename, and these keywords should appear on your web page title as well.
• Separate all keywords with hyphen rather than with underscore.
• Keep your sub-directories name as short as possible.
• Restrict the file size to less than 101K because Google chops almost everything above that.
