Don’t steal my information

By: Nicholas Tan
It’s important to take the precautions to protect you andyour products from information theft these days, because it’s getting easierand easier for people to share digital products.? Information theft is a type of computer securityrisk and it’s defined as stealing an individual’s personal or confidentialinformation.? When this is stolen thiscan cause as much damage, or possibly more then hardware or software theft.? Business or home users are both at risk ofinformation theft. One example is a malicious individual stealing credit cardsso they can make unauthorized purchases on another person’s account. Ifinformation is transmitted over a network then it has a very high chance formalicious users to intercept the information. Every computer in the path ofyour data can see what you send, and they can also see what you send.? A lot of companies try to stop informationfrom being stolen by applying some user identification and authenticationcontrols. These constraints are best for protecting computers along a company’spremise. However, to protect information on the Internet and on networks,companies use a handful of encryption methods.?Encryption refers to the process of converting data into an unreadableform. One type of encryption software is Obfuscated code which is a programming languagethat is extremely hard to read. Encrypted data is like any other data becauseyou can send it through a lot of options, but to read it you must decrypt ordecipher it into a more readable form. Throughout the encryption process, theunencrypted data or input is known as plaintext and the encrypted data, oroutput is known as ciphertext.? Toencrypt information, the programmer converts the plaintext into

ciphertext using some type of encryption key. An encryptionkey is the programmed formula that the person who receives the data uses todecrypt the ciphertext. There are a variety of encryption or algorithm methods.However, with an encryption key formula, you will be using more then one ofthese techniques.? Some business useavailable software, while others develop their own. When an individual sendinformation online such as through an email for example, they will never knowwho might intercept it, or to whom it could possibly be forwarded to.? That’s why it’s not such a good idea to sendconfidential information online.

However, an individual can help protectthemselves by encrypting the information, or signing it digitally. Some verypopular email encryption software is known as Pretty Good Piracy (PGP) and CenturionSoft Secure Protection.? Pretty GoodPiracy is known as freeware, which means that individuals can use it for theirpersonal needs but not for commercial purposes. You can download this for nocost. A digital signature is a type of encrypted code that a individual,website, or company pastes to an electronic document to make sure that theindividual is who they claim to be.? Thecode will most likely consist of the user name and a hash of usually part ofthe message. A hash is a type of mathematical formula that generates contentfrom a specific message, so it is different from a message. The recipient willhave to generate a new hash from the received message and compares it from theone with the digital signature to make sure that they match appropriately. Themain purpose behind using digital signatures is to make sure that it’s not adeceiver participating in the transaction. So, digital signatures help narrowdown e-mail scams. A digital signature can also make sure that contents of amessage have not been changed. A lot of web browsers use encryption that isregarded as 40 bit encryption, and this is a very low level. A variety ofbrowsers also offer 128 bit encryption which has a higher level of protectionbecause the encryption key is longer.?Some important places that require extremely hire security like banks,and online retailers needs at least 128-bit encryption. A website thatsuccessfully uses encryption methods to secure information is known as a securesite.? A secure site uses digitalcertificate with security protocol.? Thetwo most popular security protocols are secure sockets layer, and secureHTTP.? A digital certificate is a noticethat verifies that a user or a website is for real or not a scam. A lot of ecommercewebsites will usually have digital certificates. A certificate authority (CA)is an authorized company or individual for that matter that has the ability toissue and verify digital certificates.?There are several of websites that offer a digital certificate. Somepopular ones are Verisign, Godaddy, Digicert, and Thawte. The digitalcertificate will usually contain information such as the username and theserial number of the certificate. By the way, the information in the digitalcertificate is also encrypted. Next, the Secure Sockets Layer (SSL) providesencryption of every detail that passes between a server and a client.? SSL also requires the client to have adigital certificate, so the web browser can communicate securely with theclient.? The web pages that use SSL willusually begin with https as opposed to http. SSL is available in 40 and 128-bitencryption. Secured HTTP (S-HTTP) allows individuals to choose encryption fordata that pass through a client and a server.?When using S-HTTP, the client and the server must have a digitalcertificate.? This makes S-HTTP moredifficult to use then SSL, but on the other hand, it is more secured. Companiesthat have to use verify a client such as online banking companies use S-HTTP.Also, mobile users can also access computer networks through a virtual privatenetwork. When mobile users successfully logon to a main office using some typeof standard Internet connection, a virtual private network (VPN) allows themobile user to secure the connection.?VPNs encrypt data as it passes from a notebook computer or any othermobile device so it won’t be intercepted.?Regardless of your security method, I will highly recommend using themost powerfulness safeguard which is a backup. It prevents data loss from severalof sources such as system failure for one.?A backup is simply a backup of a file, program, or desk that can be usedin place of the original if its loss, destroyed, or corrupted.? If the files are destroyed, then you canreplace them by restoring itArticle Search, which copies the backed up files into theiroriginal position in the computer.
