Computer Security Company – In a nutshell

Its no doubt that computers have revolutionized the entire world that no one of us can now imagine a day without computer. For all tasks that we do, be it a simple calculation to complex animation and design, we seek help from these human machines. Most of us are dependant on computer for our living also. Having said all these, one must also know how vulnerable these machines are to threats and viruses. There are thousands and thousands of intelligent hackers who are doing their best to create powerful threats day by day. How can you protect your computers from these harmful threats? Is there an efficient way to protect your system? If you have these queries in your mind then the following content will help you a lot.

Computer Security is nothing but information security that protect the data and information stored in your computer from dangerous threats like viruses, malwares and also suspicious programs that corrupt these data. There are lots of companies today which deal with different types of computer security and choosing the right one is again the responsibility of the users. The best option to buy a antivirus software from leading companies in the market along with your computer. These act as a guard to your computer and may protect them. One should also buy the original version of these software from trusted computer security companies as pirated versions may in turn spread harmful viruses. One you have installed them, you got to scan your system regularly to identify the threats and clean your system.

Stale antivirus software are no longer helpful as they may be out dated. So you must update your security software periodically by subscribing to the auto updates from the security company. Some of these companies also offer free auto updates and thus helps you to save your hard earned money.

By controlling the botnet hackers can make a profit in several ways. The botnet can be used to exhort ransom money from companies by threatening to launch destructive “Distributed Denial of Service” (DDoS) attacks on web sites. They can also rent a botnet hackers.

The most common way of profits from a botnet is to use it to send spam email. According to security software firm Sophos more than 50% of all spam now comes from botnets. Hackers use spam email to drive traffic to pay-per-click advertising sites or distribute a virus program further. Using zombie computers to help cover their tracks.

The urge to produce a clear advantage in the form of a new virus called “Ransomware” by security experts who began to emerge in the year 2005. Ransomware, such as the name suggests, store data on your computer “hostage.” Files on the hard drive will be encrypted with a password. Users then contacted and asked to pay a ransom to release the files.

Here are some tips and simple strategies to help prevent your computer turned into “Zombie.”

• Keep your computer up to date with the latest software patches for Windows and other Microsoft programs. Most viruses and other malware exploiting vulnerabilities in widely used programs.
• Install anti-virus that has a good reputation of this program. Saving definitions up to date and scan your computer regularly.
• Install a personal firewall or buy a router with firewall hardware. Ideally you need a firewall solution that filter traffic both in and out of your computer to the Internet.
• Do not open spam email or email attachments related to frequently used to distribute virus programs. Use a spam filter to help reduce the amount of spam you receive.

The motivation behind hackers has evolved felt during the last few years. Develop a dangerous virus is less about “bragging rights” or satisfy the ego of the creator and becomes more and more about profit or commercial produce again.

Destruction of data on your computer or corrupt the program you use is a common side effect and what is traditionally associated with computer viruses. The reformatting of your computer “c: drive”, especially in the workplace, and the loss of valuable data that is used to be a very painful experience.

Wide dissemination of data back up solution in the company to comply with laws and other factors which means less and less valuable data is now stored on your computer’s local hard disk. More important for this attack the virus writers do not produce many tangible benefits, so not much motivation to develop programs more sophisticated applications to combat increasing anti-virus and network security company.

However, there are advantages for the virus writers in turn your computer into a spam distribution machine. “Spam” is email sent without the permission of the person receiving the message. Hackers control your computer through a Trojan Horse that gives them access rights the same as the user. Once your computer is controlled by hackers that became known as “Zombie.” A group of zombie machines known as “botnet.”

They are the three elements of the Broken Window theory to make it work – community action, official support and action and punish the perpetrators.

The first element in the fight against click fraud as a community in getting click fraud prevention and tracking software into the hands of all advertisers. Difficulty sorting through hundreds of pages of data to make comparisons and patterns that signal filtering click fraud is a scary one for most companies.

Click fraud detection software make it almost without any pain – but can be expensive. Another part of the Internet market has taken advantage of open source software to manage content, manipulate graphics, and create a community and the payment process. Offering open a free click fraud prevention software will encourage advertisers to begin monitoring their own logs and records and to identify potential fraudulent clicks.

In addition, an open offer to encourage others to modify and extend the software and create extensions that are available to the public.

With their monitors in place, the second part of the equation becomes more possible. When easy for advertisers to identify and document fraud clicks on their campaigns, be easier for them to claim a refund for those clicks. The third part is the result of creating a society that actively works to eliminate click fraud.

For now, click fraud around the broken window. With the right tools, we can begin to repair the windows and create a community that makes almost impossible to go with their tactics.

What happens when:

- The PPC provider of software detection methods do not catch click fraud?
- The advertiser does not use fraud detection software?
- The advertiser can not back up claims of click fraud?
- The main players in the industry refer to the problem as ‘negligible’?

Simply put – click fraud will get away with it. Big rewards – estimates the amount of money lost to click fraud in the range of billions of dollars every year. But the loss of advertisers for each individual is usually negligible, and even Google sees refunding money to advertisers as nothing more than the cost of doing business.

If we are ever going to put a dent in click fraud, three things must happen.

1. Advertisers will be responsible for monitoring their own campaigns. If you do not know it happened, you can not take steps to stop it.

2. Advertisers should use the information they produce through their analysis to demand refunds from PPC companies consistently. During a small loss compared with a profit for the PPC companies, their incentive to respond is limited.

3. Click fraud perpetrators must be identified, pursued and punished actively. Today, modern techniques that use proxies and ‘zombie networks’ can make almost impossible to identify and punish the perpetrators.

There is a theory in which law enforcement goes like this:

If someone breaks a window in a building, and are not fixed quickly, the others will soon be broken. As evidence of neglect to build, will be more daring intruder to enter the building and do more vandalism and eventually destroy completely.

If, on the other hand, the window was quickly repaired, it was reluctant to further a crime because it is clear that someone watching the store.

Furthermore, if not just fix the window, you find a destroyer and hold them responsible for it, a message came in loud and clear: we’re watching and you will get caught.

The problem with the broken windows theory is that it takes more than police action to put into practice. If people are not involved in cleanup efforts, the initiative failed. When people are interested in helping police the problem, to report them and to ‘mind the store’, so to speak, decreased crime rates.

This theory can be extended to the police almost every place where there is behavior that is unacceptable – including click fraud problem in the PPC ad. At this time, the PPC industry is like an empty building no one watching the store. It’s easy to enter fake clicks. Will be easier to get away. At this time, the percentage of advertisers left the detection of invalid clicks to PPC providers – and the policy of most PPC providers is that they will provide a refund to prove click fraud at the request of the advertiser.

Before asking citizens to participate in and adapt to various online systems, is very important for the Government to follow the standards and maintain its online security. SSL certificate is as important as the public voice and support for the Government to survive.

The consequences are not held in SSL Certificate Public Sector / Government site –
• Government agencies / organizations will lose credibility if it does not take security measures accordingly. Public sector plays a very important role in the economy as a whole and the direction of a country. It is important that citizens believe and trust in government agencies and institutions of other public sectors.
• Technologizing public sector is a dream come true for most advocates of technology, because technology is improving efficiency. Very difficult to get people to use the online system, if the security measures are not used effectively.
• The public sector tends to deal with highly sensitive information in the domain such as defense and national security. Security is very important information for the state and can not be compromised at any cost. This is one of the highest levels of security requirements.

As government and public sector to be upgraded to the Internet, higher technology, and electronic transactions to achieve their mission and goals, they must have security as part of this because they can not ignore the importance of SSL certificates as they assist in addressing online risks security.

Why the Government Sector need SSL?
E-governance refers to online government operations such as online voting, remote access to government networks for communication, coordination and collaboration purposes, online tax filing, etc.
• To meet privacy, security and safety standards for a variety of online operations
• SSL certificates globally accepted for authentication and therefore can be used for remote network access to the government.
• SSL is a necessity as the reputation of the Public Sector ‘depends on the privacy and integrity.
• SSL Certificate for secure online should provide information and services.
• SSL ensures the protection of personal privacy and sensitive data.
• With SSL you can share confidential information over an intranet with out fear of hacking.
• Secured Socket Layer helps in increasing visibility and public accountability of the Government.
• Digital certificates citizens and reduce the risk of taxpayer information with privacy.
• SSL eliminates opportunities online fraud and identity theft.

And this gives an error message
Unknown column ‘user’ in ‘where clause’

That’s fine! Using this error message we can guess the column in the table. We can try to put in username field ‘or email =’ and because we did not get an error message, we know that the email column in the table. If we know the email addresses from users, we can now simply trying to ‘or email =’ testuser@testing.com both the username and password and our question becomes

select username, password from users where username =”or email = ‘testuser@testing.com’ and password =”or email = ‘testuser@testing.com’

which is a valid request and if that email address in the table we will be successful login!

You can also use error messages to figure out the name of the table. Because in SQL you can use the notation table.column, you can try to put in the username field ‘or user.test =’ and you will see an error message like
Unknown table ‘user’ where clause

Nice! Let’s try it with ‘or users.test =’ and we
Unknown column ‘users.test’ in ‘where clause’

so logically there is a table named users:).

Basically, if the server is configured to provide an error message, you can use it to calculate the structure of the database and then you may be able to use this information in an attack.

CREATE TABLE users (
username VARCHAR (128),
password VARCHAR (128),
email VARCHAR (128))

There is one row in the table with the data:

username: testuser
password: testing
email: testuser@testing.com

To check the credentials I created the following query in PHP code:

$ Query = “select username, password from users where username =’”.$ user.” ‘And password =’”.$ pass .”‘”;

Server is also configured to print an error triggered by MySQL (this is useful for debugging, but should be avoided in the production server).

So, last time I show you how SQL injection works basically. Now I’ll show you how we create more complex queries and how to use the MySQL error message to get more information about the structure of the database.

Let’s get started! So, if we just put ‘characters in the username field we get an error message like
You have an error in your SQL syntax; check the manual that match your MySQL server version for the right syntax menggunakan”dekat”dan password =” ‘at line 1

That’s because the demand to

select username, password from users where username =” ‘and password =”
What happens now if we try to put in the username field strings like ‘or user =’ abc?
Inquiry into

select username, password from users where username =”or user = ‘abc’ and password =”
