Professional and personal life: properly configure Facebook

Organize lists

The Facebook lists allow you to share information (articles, links, content) within groups. They therefore act as filters: information shared with a list are only visible by contacts belonging to this list. This settings makes it possible to separate a personal (family, friends) from professional use(eg list of colleagues).

• Lists can be used to share information on the progress of a collaborative project (event), allows the geolocation of relationships to distribute information in a meaningful way.

Note:

• Your contacts are not notified when you add them to a list.
• You can add contacts to multiple lists.
• Facebook offers several types of default lists settings. One of them (Restricted list) allows you to add contacts who won't hve access to publications and information shared publicly on your profile.

Modify your privacy settings

The following privacy settings must be changed if you are using Facebook for both a professional and personal basis. They are available under the following section: Home> Privacy settings:

• Change your default privacy settings :The default privacy settings of Facebook are not efficient enough, you can pre-set the visibility of content on your Facebook account, to a targeted audience.
• Geo-location settings : Avoid getting tracked.
• Apps and Websites: Prevent applications to access your private data.
• Limit the Audience for Past Posts.

Security Settings

Security settings can be accessed by going through: Home (top right of your Facebook page)> Account Settings> Security (tab on the left column):

• Enable secure browsing (HTTPS secure connection), specially if you make a frequent use of unsecured WiFi networks.

Secure your Facebook profile using applications

Several vendors offer security applications for Facebook.

• BitDefender offers a free application for Facebook called "Safego" (also available under Twitter) that analyzes the user's wall, posts and comments to identify malicious links and other content such as images, videos.
• It also provides an "index of confidentiality" to help the user to manage privacy settings of their profile. Norton Safe Web application for Facebook allows Symantec to analyze the news feed links that may be potentially malicious.

The use of proxy servers

Access to Facebook can be blocked in different contexts (at work, at school, traveling abroad). To overcome this limitation, many users go through servers called "proxies" or proxy, which serve as an intermediary between a Web browser and Internet. Several lists of proxy servers available on internet.

• Note that: it is impossible to know if the data passing through the proxies aren't being intercepted and reused maliciously.
• It is therefore important to be careful when using this type of service.

Spam and Scams to avoid on Facebook

Facebook and Norton by Symantec published a joint white paper for an expert safe use of Facebook, titled "Spam and Scams to avoid on Facebook"

Among the main advice of this White Paper:

• Be cautious of videos or links with sensational headlines.
• Activate the privacy settings of your account.
• Use passwords that are difficult to guess.
• Be cautious towards "attractive" free offers (discount coupons, games, etc.), especially when asked to click on the "I like" button before accessing the content.

Safety tips from Facebook

To protect your account, Facebook also recommends:

• To use an up-to-date web browser, equipped with anti-phishing features,
• Ensure the updating of security software on your PC (firewall, anti-virus, anti-spyware, anti-phishing tools).
• Not open attachments in received e-mails (unknown senders).

ATM hacking is from past is the first interest of every computer hacker.And in this article i will talk about ATM Hacking, things like how ATM Works , What are the vulnerabilities available to exploit and last but not least YES, how to patch them. So starting from the first how ATM works.

WARNING
 Hacking ATM is highly illegal. Can Put you into cell for minimum 3 years along with fine 7 lac.This article is just for education purpose only do respect the law in your country, the author of the tutorial do not held any responsibility of the act or trails performed by you after reading the article.

How ATM Works
An ATM is simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is analogous to an nternet Service Provider  (ISP) in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash).

Most host processors can support either leased-line or dial-up machines. Leased-line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line. Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll-free number, or through an Internet service provider using a local access number dialed by modem.
Leased-line ATMs are preferred for very high-volume locations because of their thru-put capability, and dial-up ATMs are preferred for retail merchant locations where cost is a greater factor than thru-put. The initial cost for a dial-up machine is less than half that for a leased-line machine. The monthly operating costs for dial-up are only a fraction of the costs for leased-line.
The host processor may be owned by a bank or financial institution, or it may be owned by an independent service provider. Bank-owned processors normally support only bank-owned machines, whereas the independent processors support merchant-owned machines.




Methods of Hacking ATM

1. Magnetic Reader
Most ATM hackers have a device called Magnetic Reader which they attach over the card slot on the ATM, and as any one pin the card inside automatically it reads the magnetic information. And with the advancement of time the with the help of wireless technology, the magnetic reader automatically transmitted the details to fraudsters in a nearby location.

2. Hidden Camera
Obviously this is one of the easy method to hack an ATM machine but this is something more than hack, here we are not penetrating the ATM. As we all know our ATM is protected by a PIN which acts as our password so if some one have to get money after stealing our card he/she should have the PIN code too,  these days criminals have a solution for this too.

3. They enter into the ATM when guard is outside put hand on the ATM cam and silently in 5 or 6 seconds,  just  install a hidden camera near by the keypad of the ATM from the user enter his/her PIN CODE, and again using the latest technology (wireless) and the PIN is digitally recorded and now hacker have the choice whether he want to get the details remotly or he/she will go to ATM and get the details by himself/herself.

Protection Against ATM Hacking
1. Do Hide the keypad when you enter your PIN CODE.

2. See All around if found any camera which you think not supposed to be there do inform the ATM guard and the near by Bank.

3. DO confirm completeness of the transaction after getting the money most people get trapped into this as the said above in second method.

4. If any criminal caught to and say to extract money from ATM, to save your money just reverse your PIN Account number. Like if my PIN CODE is 1234, if some one having PIN Code like 7777 then just put a 0 (Zero) in the last digit, money will stuck half in the ATM and half outside.

RAM (Random Access Memory) is the memory which computer uses to work on different processes. The more RAM you have, the faster the process is. Usually, these days the computers come with atleast 1 GB of RAM. But, that’s not enough to run some High Memory consuming softwares. Especially, the Games require a big amount of RAM to play smoothly. I have faced many problems with Games on my computer due to RAM. So, here I am going to show you how you can use your USB Pen Drive as RAM. The process explained below is for Windows 7 OS. For other, it might be slight different.

 Step 1: Go to Start followed by Control Panel.

Step 2: Click on System and Security, then select System.

 Step 3: Now select Advanced system settings from the left side.

Step 4: The dialog box will open in Advanced tab, click on Settings, then go to Advanced tab.

Step 5: From there, you will see Virtual Memory, just click on Change…

Step 6: In Windows 7, the box Automatically manage paging file size for all drives comes prechecked, so we have to uncheck it to perform the operation.

Step 7: Now, from the local drives list, click on your Pen Drive letter, eg. H and set the Custom Size for it. If you have 4 GB Pen Drive, then enter 700 in Initial Size and 3072 in Maximum size and hit Set.


Now, the computer will restart and everything is done ! 
Enjoy it .
