For those of you who are not familiar with SQL language, in SQL the ‘character is used as a delimiter for string variables. Here we use it to limit the string username and password provided by the user.

In this example we see that the username and password supplied in the query entered into between ‘and the request is then executed by the database engine. If the request for re every line, then the mandate is valid (existing user in the database and have the password provided).

Now, what happens if a user types in ‘character into column username or password? Well, by simply putting ‘into the field and stayed username password blank, the question will be:

SELECT * FROM users WHERE username =” ‘AND password =”

This will trigger an error, because the database engine will consider the end of the string on the second ‘and it will trigger a parsing error in the third’ character. Now let us what would happen if we send this input data:

Username: ‘OR’ a ‘=’ a
Password: ‘OR’ a ‘=’ a

Questions will be
SELECT * FROM users WHERE username =”OR ‘a’ = ‘a’ AND password =”OR ‘a’ = ‘a’

Because it is always equal to a, this query will return all rows from the table the user and the server will “think” we are provided with valid credentials and let as in – SQL Injection work:).

Now we’ll see some more advanced techniques .. For example I will be based on PHP and MySQL platform. In the MySQL database I created the following table:

SQL Injection is one of the most common security vulnerabilities on the web. Here I will try to explain in detail the types of these vulnerabilities with examples of bugs in PHP and possible solutions.

If you are not so sure about the programming language and web technologies you may be wondering what he lived for SQL. Well, this is an acronym for Structured Query Language (pronounced “sequel”). It’s “de facto” standard language for accessing and manipulating data in the database.

Currently most websites rely on a database (usually MySQL) to store and access data.

Example we will sign a general form. Internet surfers see people login every day, you enter a username and password on the server and then check the mail that you provide. Ok, it was simple, but what happened exactly in the server when he checked your credentials?

Client (or user) to send to the server two strings, username and password.

Usually the server will have a database with a table where user data is stored. The table has at least two columns, one for storing a username and a password to enter. When the server receives a username and password strings he would query the database to see whether the mandate given is valid. He will use the SQL statement that may look like this:

SELECT * FROM users WHERE username = ‘SUPPLIED_USER’ AND password = ‘SUPPLIED_PASS’

Security is key

Because the HIPAA law provides for civil and criminal penalties for violations, data and security access of the most important. To ensure compliance with HIPPA, online document management on the company intranet and extranet should include several security features:

• Secure web server – server running secure socket layer is the minimum amount required.
• Encrypted database – all data must be encrypted. This software is available that will be encrypted all data sent between two computers via the internet.
• Secure access control – in addition to the traditional user id and password, this may be a good idea to use a strong password or smart card as an additional security.
• Limit time – this ensures that confidential data is not left on the screen that is not guarded.
• Server Monitoring – a secure web servers need to be monitored closely to detect the break-in attempts.
• Regular security audits – regular audits required to ensure all safety precautions are working correctly.
• Personnel – the maintenance of the system must be in the hands of qualified personnel familiar with the requirements of HIPPA

Share of private health information through the internet can be a risky business. Unfortunately, as people become accustomed to doing most if not all of their personal business online, the demand to access this information online will grow to the point that health care providers will have no choice but to also provide access to private health information or lose their customers.

Health Insurance Portability and Accountability Act (HIPAA) was enacted to ensure the confidentiality of patient information. This requires health care providers implement strict measures to ensure that the information shared on the Internet is protected from unauthorized access.

The laws which provide HIPAA requires healthcare entities to:
• Assign responsibility for security to a person or organization.
• Assess the security risks and determine the main threats to the security and privacy of protected health information.
• Establish a program to address physical security, personnel security, technical security controls, and security incident response and disaster recovery.
• declare the effectiveness of security controls.
• Develop policies, procedures and guidelines for the use of personal computers (workstations, laptops, handheld devices), and mechanisms to ensure that where possible, limit and stop access (access control lists, user accounts, etc.) appropriate to the status of the individual , change of status or termination.
• Implement access controls that may include encryption, context-based access, role-based access, or user based access; audit control mechanisms, data authentication and entity authentication

This law has serious implications for organizations that allow unauthorized access resulting in violations of confidentiality.

Hard to believe, not everyone has a DVD player. Not everyone should even want it. Are you the type to VCR? Then there is a hidden digital video recorders and VCR-like. This is useful to record a video recorder in 1280 and even 1440 hours of video time interval. They can also record up to four hundred and forty-five hours of real-time video and all the 180 VHS tapes.

Some of these machines is nearly half the size of a regular VCR and comes with a battery back-up, date and time generator, a variety of records, key records to prevent unauthorized interference, and a programmable timer. You can even get a lighter with the adapter cable and remote IR sensor for use in buses and taxis, and a video motion detection chip, the unit only records when there is movement is really present.

If the security is very important to you and you have more than one camera in operation, how you can simplify the operation hidden digital video recorder? That is where a quad system comes into play. This system supports four different cameras at the same time, saving the high cost of operating four different monitoring systems. With a great plug and play interface, quad system can monitor four cameras simultaneously, and shows the four views on your computer screen at the same time, or if you prefer, you can watch each camera view individually. It’s really up to you.

There are two main types of information where access needs to be managed;

1) Company Information
2) Personal Information Private

Companies restrict access to certain information on their computer networks as a matter of routine. Not everyone will be able to access last month’s sales figures or to know detailed plans for next year. All the people accept this as reasonable and protection against speculation in the stock company.

Management of sensitive information of this type can be achieved by a firewall and password protection in corporate computer networks. Access to information can also be at various levels, such as read only or editing rights.

Backing up data on a daily basis is an important part of a company’s disaster recovery plan. Highly sensitive information may not be stored in a computer network is connected. Hacker is a network security threats that most IT managers are aware of.

Every company and government agencies also collect information about us. Which may be as simple as a database of phone numbers and addresses, or can include Social Security numbers and driving license details. There are laws that apply to limit the information accessed and used.

Government agencies and large companies are usually in full compliance with all state laws and federal information management. They have personnel exclusively responsible for managing database information.

Small businesses may be less vigilant in their compliance, not through lack of will, but through lack of knowledge or time management. When there is effectively one person makes all the planning and management decisions within a company, the policy for the management of information is not always high on the agenda.

You have the right to see information that every company or holding in your organization and to have it corrected if there are inaccuracies. You also have to ask what the company uses the information to, either for marketing purposes or whether the information is shared with other companies

That time was the year, November 20, commonly known in the retail trade as a ‘Black Friday’ has come and gone. Hacker is now running smoothly, tease and lure us into parting with cash and our identity to an empty promise. Black Friday, known in the retail trade as the beginning of the holiday shopping season is also the busiest period of the beginning of the Hacker. This year, the biggest concern among web technologists-borne malware.

Black Friday, the day after Thanksgiving, followed in marketing lingo by Cyber Monday. Both are big days for retailers and online fraud. Consumers should be careful to e-mails advertising incredible deals that seem too good to be true.

Email claiming to come from eBay, Amazon or E-tailors Specialist hide the true address of the website that you are directed to visit through a link is clicked. Another trick is to send (the explosion) is not guilty of an email to Internet users, advertising hot products is much smaller than usual retailers. Hot product this year will, in our opinion the electronic goods such as Nintendo Wii and very likely the Amazon Kindle, who both looked set to be sold out!

Firewall seems to be in fashion today. For those not familiar with what a firewall, It pretty much is a program that is between you and the outside world, thinking about the toll that stood at the edge of your world and the digital world.

It’s billed as a one-stop solution to prevent hackers and unauthorized access by intruders (both human and robot generated). However, firewalls can not be attacked.

One may also smart hacker could hijack your firewall and make it perform in ways that are not to your advantage. There are good online testing services are free or charging a fee for signs that will help you check to see if your firewall is working or not, or whether it has been compromised.

You may also find that the firewall will not always work properly with other programs, such as antivirus and anti spyware related software. This can usually be arranged within the firewall program, where you can configure which programs and services on your computer are allowed to travel back and forth between you and the network.

If you are not familiar with firewalls at the moment, do not worry. Most of the offerings in the marketplace is very easy to install and setup. However, a small disturbance may be that in some locations, every time you open a new firewall program may give you a pop-up box that asks how you want to configure access to it.

Beyond that, no big deal, worked like a charm. So if you have a firewall is not configured for your computer or your network, then maybe it’s time you do it.
