Do we need information security?

Nowadays Data and information security is the most popular concept. Since technology is developing as a part of our life, Even If you are a technical person or not, we all have to aware of security threats and prevention methods.

Have ever think, how valuable our personal information is? Definitely, those are our assets which can be sold for millions and billions. Everyone has some details regarding them, what they like to share with everybody, or with a particular person or group. Sometimes may not with anyone. So we have all the right to decide what should be private, what should be public and whom we should share with. Consequently, our information should be protected according to our requirement.

Is that only thing we have to deliberate about information? Not exactly. Our information not only is with us always. We might have to save it somewhere, which we assume as safe. Sometimes we have to retrieve it from the storage media whenever we need. And we have to share that information with someone else in a secure manner. Therefore the application we saved information, the machine where an application runs, the devices which are connected to the machine and the transmission media/ network which transmit the information should be protected strongly from intruders’ attacks.

So everyone owes to take steps to secure their information.

“At the end of the day, the goals are simple : safety and security” – Jodi Rell.

Synchronizer Token Pattern

Synchronizer token pattern is one of the prevention methods for Cross-Site Request Forgery ( CSRF ). It uses a value called CSRF token which is unique for a session identifier. When the user login to a website, the server generates a random value called token for a particular session. The token is saved on the server as well as the browser (after obtained from the server). PHP identifies the session using the session variable ‘PHPSESSID’ which is also stored in the browser as the cookie to identify a particular session. The server validates the user when each request is made, via comparing the token value in the server and token value in the browser. Through this write up how synchronizer token pattern is implemented and how does it works will be described. (Click on the images to view clearly) Source code of the implemented program can be downloaded from here . I have implemented a login page called index.html to enroll a user to the server. T...

CSRF - Cross Site Request Fogery

Cross-site request forgery (CSRF) is an attack where the legitimate user trapped by an unauthorized user to perform an unintended task to a website where they are authenticated. Since HTTP is a stateless protocol, cookies are used to validate the request agent. Once the user login to a website, it will not require to type the username and password for each attempt. Hence, for the server to identify the user, the server generates a session identifier and sends it as a set-cookie header to the client browser with the very first response. The cookie set by the server will be saved in the client browser and, the cookie will be sent along with every request made to the server (Where the domain and path are matched). However, the server does not check any other attribute but session identifier. Although the request is made from another client, the website only verifies whether the requesting user is already authenticated or not, using a cookie. For example, if a person logged in...
