They ensure the safety and the security of our data and information and guard it from any catastrophe. We call them “Ethical Hackers”. So, how does it sound to be an ethical hacker? Does it fancy you? If yes, there are few brief points you might want to look and understand to be a professional ethical hacker

Facebook Exposes Personal Data

In July 2012, there was a similar breach where a private security consultant used a piece of code to gather information on over 100 million profiles. This was not seen as a hot topic issue because the information gathered was not secured by the user, and therefore in the public domain. But, it does brings up some interesting points which many users seem to forget when they surf or post to social media.

For any social media sites, you should follow these rules:

1.Do not post private information on the internet, regardless of security or visibility options. If you are not comfortable with sharing your location with 1.1 billion users, it is strongly recommended you avoid posting that information. Be wary of who might use your profile against yo

2.Try to keep separate social media profiles for work and personal. LinkedIn and Facebook are perfect examples. LinkedIn, while useful for businesses, is not geared towards someone looking to keep in touch with friends and family. Facebook, is useful for both business and personal. But, keep in mind it is first and foremost a personal website.

 3.Check your privacy settings. Facebook in recent years has really stepped up their game on how best to protect personal user data. One can now determine which posts and pictures can be seen by whom. You may decide you want your friends to see your new car, but do not necessarily want your jealous ex to know. This is done by simply changing the visibility setting on each post. It can also be done globally if you prefer.

4. The internet does not forget. Remember the ‘accidental’ drunken photo you posted online and thought you deleted? Odds are: somewhere out there remains a copy someone snagged before it was taken offline. This and other posts you might have created, could be used against you in a malicious manner. Think before posting. In other words: ‘Never post anything you don’t want printed on the front page of the paper.’

 

 

Secure Your Web Application Own House

The Front Door.
The front door of any web application is the login page and, not surprisingly, it is the primary point of attack. A login page will consist of edit boxes to type a user name and password and a button to send these for the server to authenticate your access to the rest of the web application. Some login pages may provide a captcha to make sure you are a human being and not a mock-up of the same form on a different server. The mock-up form will cycle through variations of user names and passwords until it gains access to the application. This is known as cross-site forgery and is akin to a burglar forging the keys to your house.

Captchas are jumbled images of scrambled letters and numbers which make it impossible for an automated script to read. Unfortunately, as the scripts become cleverer at reading these images, the captcha images need to become more complex and harder for humans to read. This causes frustration for the end-user as they have repeated failed attempts at gaining access to their account because the captcha was unreadable. The solution to this has been to replace the captcha with a secure token. The secure token is generated my joining the user name, password and any other user information available with a uniquely generated key. This concatenation is then encrypted and stored as a hidden field in the form, thus making it impossible for any mock-up form to make a successful login attempt.

The Windows and Back Door.
What are the windows of a web application? I don’t mean the operating system on the server. I’m talking about potential areas of each page which could be broken to make a forced entry. These areas are edit boxes and text areas which allow a user to type information. An attacker will use edit boxes and text areas to enter commands which the database understands. If the software is not written securely then it is very easy to interrupt the database when it is saving the data, so that it will execute the commands supplied by the attacker. Typical attacks could result in the database being destroyed, data being stolen or user information being compromised. This type of attack is known as SQL injection.

Boundary Fences.
The boundary fences of a web page are any links, editable areas and the main URL address. The URL of the page itself and links embedded in the page can be copied and modified from another site so that commands can be executed by the server. Javascript code can be inserted into editable areas to force data to be submitted to a rogue site or to gain control of the user’s web browser. Database commands can also be inserted into the main URL address. These attacks are known as cross-site scripting (XSS) attacks because they are scripts which direct the user to an attacker’s own web site. XSS attacks could be used to steal a user’s authenticated session identifier and use it to increase the level of access of another account they have already created.r.

Impersonation.
We have all experienced bogus house callers who claim to be the gas man or the water company saying they need to gain access to your house to turn off your supply. Web site attackers may contact you or any other users of your site by email, social network or telephone and trick you into revealing your login details. Reasons they may give could be that your web site has already been hacked and they can fix it if you provide them with access. The only prevention is to constantly remind your users that they should not reveal their username and password to anyone and that you as the site owner will never ask them to reveal their password. You should provide links to allow your users to reset forgotten passwords by sending them an email link with an encrypted token to guarantee its source.
