Information Security

The latest technological advances have made the world a global village and allow communication at the speed of thought. Using the Internet, vital personal, official, or financial data can be shared or transferred across the globe within seconds. This has not only changed the very social, political, and economic fabric of countries, but has brought people closer as never before. Yet the picture is not all rosy. The hackers are not lagging behind, and they too have devised all possible ways conceivable to breach the security involved with the transmission of data. Given this scenario, maintaining the security of data is a major challenge for the IT experts.

The aim is not data transmission, but secure data transmission. The danger is not only from hackers alone. Unintended lapses on the part of employees can also be a cause of worry. There are many reasons for the leakage of data. Firstly, the employees may not be adequately trained in the techniques of data transmission. Also, technologies are constantly being upgraded. This means that training employees for handling data transmission should be a continuous process. This can be done by holding in-house orientation programs. These can be in the form of classroom teaching or e-learning programs. Classroom teaching programs have their limitations because they are expensive. The e-teaching method is cheaper, allows greater flexibility, and reaches a large number of learners from a centralized location.

Also, awareness and alertness can go a long way in ensuring that these mistakes are minimized. In fact, a recent survey conducted Ernest and Young in 2004 holds the users’ lack of security awareness as the second-greatest reason for vital information getting into the wrong hands.

Another major factor that can go a long way in protecting data is ensuring employee loyalty. This is possible if they are given their due and their needs are taken care of. Otherwise, there can be cases of bribes, and employees can sell important data to rival organizations. In the world of cut-throat competition, this factor can not be ignored.

IT Security - What Do You Need To Be Aware Of?

t's self-evident to all business people by now that the Internet is a damn scary place where viruses, spam, ID theft, malware and cybercrime threaten to compromise your identity, your hardware, your bank account or indeed your personal wellbeing. But away from the sensational headlines, the really cold reality is that all UK businesses are left to pay a tax on everything they do via technology, and that tax is called 'IT security'.

As someone who manages a business, I'm personally quite happy to pay any sort of tax so long as I can see it's going to the right cause. With IT security, you're paying to safeguard the effectiveness and productivity of your business processes. IT is intended to enhance business performance and profitability, but every increment in technology strategy within an organisation (new VoIP phone system, web applications, 3G devices, etc) actually threatens to have the reverse effect if IT security isn't comprehensively and proactively covered off.

When it comes to select which IT security solution to deploy for your specific business circumstances, it's critical to achieve the right balance between the liberating possibilities of technology and the potentially constraining effects that 'crack-down' IT security can represent. A great – though slightly spurious – demonstration of how to utterly fail to achieve this balance would be to hire an IT administrator to perform the role of 'Anti-Virus Filter'; a function typically fulfilled by some sort of appliance that checks all network traffic (emails, files transferred, etc) for viruses against an evolving database of virus signatures, administering an 'antidote' to those it finds. In doing this the advantages in terms of security effectiveness would be world-beating as I guarantee no harmful traffic would ever enter or leave your network. On the downside - unless your guy is particularly quick-fingered - you will find operational efficiency takes a ferocious beating as your entire business grinds to a halt within microseconds.

While admittedly quite a silly example, be assured that - back in the real world - the conflict this represents is played out every day in the IT infrastructures of businesses large and small. Security should be fundamentally intelligent, i.e., non-disruptive, sensitive to its changing environment, easy to get along with and very, very fast. It does NOT exist to impede or delay the business processes that you've already invested IT resources in attempting to accelerate. Beware: surprisingly few security vendors or even independent consultants seem capable of grasping this.

Another balancing act to be aware of is the challenge of increasingly complex IT infrastructures, each of which require a security 'checklist' before they can be safely implemented. The watchword here is 'flexibility', and while it’s difficult to achieve it is by no means impossible.

The double-edged sword of IT is sharpest when the question of security is posed. The skill in wielding it can allow businesses to embrace more opportunity without more risk, and more revenues without more expense.

Security Encryption

When you access Web sites from your computer or transfer data from one computer to another, always remember that there is always the danger of inadvertently making yourself vulnerable to hackers that may be present within your local area network or wireless local area network. You need to protect the data stored in your files and folders. This can be achieved through security encryption.

With today’s user-friendly software, encrypting files is easier than it’s ever been. When sending an e-mail, for example, a user can just choose to click a button on the menu to encrypt an outgoing message. But encryption is not and should not only be applied when using the Internet. As a data security protocol, encryption should be used when storing files in computers with multiple users; and before transferring files through compact discs, floppy disks, and other external memory devices. This way, your data remains inaccessible to unauthorized personnel.

Choosing the right kind of encryption system and software largely depends on the level of security you need. If you are person e-mailing highly classified files, you may need to use a more sophisticated encryption method than the ordinary guy down at the local Internet café sharing mp3s or pictures through peer-to-peer sharing. More stringent security encryption is used by large corporations and government agencies that deal with sensitive and top secret information. Their encryption systems are based on highly advanced algorithms and multiple combinations of passwords and pass keys.

Encryption software that is available to the general public must meet certain standards such as the AES standard. This ensures consumers that they are protected sufficiently and according to the specifications advertised.

There is also free security encryption software available for download from the Internet. While these programs may not be as sophisticated as those used by the government agencies, they can hold their own against minor hackers and may even deter would-be saboteurs.

Encryption Algorithms Briefly Defined

Encryption algorithms are commonly used in computer communications, including FTP transfers. Usually they are used to provide secure transfers. If an algorithm is used in a transfer, the file is first translated into a seemingly meaningless cipher text and then transferred in this configuration; the receiving computer uses a key to translate the cipher into its original form. So if the message or file is intercepted before it reaches the receiving computer it is in an unusable (or encrypted) form.

Here are some commonly used algorithms:
DES/3DES or TripleDES
This is an encryption algorithm called Data Encryption Standard that was first used by the U.S. Government in the late 70's. It is commonly used in ATM machines (to encrypt PINs) and is utilized in UNIX password encryption. Triple DES or 3DES has replaced the older versions as a more secure method of encryption, as it encrypts data three times and uses a different key for at least one of the versions.

Blowfish
Blowfish is a symmetric block cipher that is unpatented and free to use. It was developed by Bruce Schneier and introduced in 1993.

AES
Advanced Encryption Standard or Rijndael; it uses the Rijndael block cipher approved by the National Institute of Standards and Technology (NIST). AES was originated by cryptographers Joan Daemen and Vincent Rijmen and replaced DES as the U.S. Government encryption technique in 2000.

Twofish
Twofish is a block cipher designed by Counterpane Labs. It was one of the five Advanced Encryption Standard (AES) finalists and is unpatented and open source.

IDEA
This encryption algorithm was used in Pretty Good Privacy (PGP) Version 2 and is an optional algorithm in OpenPGP. IDEA features 64–bit blocks with a 128–bit key.

MD5
MD5 was developed by Professor Ronald Riverst and was used to create digital signatures. It is a one–way hash function and intended for 32–bit machines. It replaced the MD4 algorithm.

SHA-1
SHA–1 is a hashing algorithm similar to MD5, yet SHA–1 may replace MD5 since it offers more security.

HMAC
This is a hashing method similar to MD5 and SHA–1, sometimes referred to as HMAC–MD5 and HMAC–SHA1.

RSA Security

  • RC4 – RC4 is a variable key–size stream cipher based on the use of a random permutation.
  • RC5 – This is a parameterized algorithm with a variable block, key size and number of rounds.
  • RC6 – This an evolution of RC5, it is also a parameterized algorithm that has variable block, key and a number of rounds. This algorithm has integer multiplication and 4–bit working registers.

    An Introduction To Encryption

    Encryption is a method of compressing data files into a format inaccessible to unauthorized people. Technology used in encryption activities was once used exclusively by top-secret military and government operations. Now, even ordinary people can use encryption software to ward off a different kind of spy—hackers that steal identities and spread viruses.

    Company executives are often advised to use encryption when transmitting sensitive data over the Internet. E-mail must be protected from possible corporate saboteurs. Most E-mail service providers provide an additional encryption feature.

    Encrypting emails can be as easy as clicking an icon on the menu bar. Even IT hubs like cafés, hotels, and offices have networks that use encryption systems to protect users from hackers in addition to other security tools like virus scanners and firewalls.

    WLAN or wireless local area network users or those that access the Internet through wireless connectivity are often advised to use encryption methods to keep their hard drives, folders, and transactions off limits to people with malicious intent. Protection is always key when accessing the Internet.

    Encryption has many levels of sophistication and formidability against attacks. The kind of encryption you can use depends on your software and your technological know-how in implementing encryption. Decryption or the process of deciphering encrypted messages or data is also a part of the encryption system. In this world of wireless connectivity, it is hard to tell who is eavesdropping and stealing your most confidential information. Better be armed against them. This is not to say that encrypted messages are always safe from hackers. The best of the lot may be able to get past the password-protected protocol, even with the best encryption software. But at least these tools can slow down hackers, and the inconvenience alone may deter them from their devious pursuits.

    Windows Vista - Which Version Do You Need?

    After deciding to shift to a Windows Vista OS, you need to decide on which Windows Vista version you should pick. Before you consider shelling out $400 for a Windows Vista Ultimate license, you really should ask yourself exactly what features you need and want so you can decide whether the price is right.

    Windows Vista Home Basic

    This is the most rudimentary version of Vista available. It has the more secure IE 7, the firewall, the quick search functionality, and easier connectivity. When it comes to the features that distinguish Vista from previous versions of the Windows OS, though, Home Basic is somewhat lacking, though it does offer parental control.

    Windows Vista Home Basic is a good choice only if you use your computer solely for web surfing and basic document processing, or if your computer is just barely powerful enough to run Windows Vista.

    Windows Vista Home Premium

    For an extra $40, you can get much more out of Windows Vista. Aside from including all the features of the Home Basic version, Home Premium offers all of the window-dressing that makes Vista look like Vista. You will have pre-packaged games and Aero interface capability. Aero gives your windows and icons a 3D appearance and smoother transitions, as well as allowing you to add transparency effects to window borders. Home Premium offers tablet PC functionality, document collaboration, and scheduled backups. Home Premium also offers the fully integrated Windows Media Center for all your home entertainment needs, plus a moviemaker which is HD format-capable.

    Windows Vista Home Premium is designed for the user who uses the computer for PC and network gaming, since Premium supports DirectX 10, with its advanced graphics technologies incredible graphics rendering. Premium is also designed for watching High Definition movie, editing/making video clips, burning DVD copies, and interfacing with the Xbox 360, which Home Premium edition automatically detects to allow for Video, Audio, and Picture sharing.

    Windows Vista Business

    Windows Vista Business drops Parental controls, Media Center features, and pre-installed games for obvious reasons. Vista Business does have the rest of the Home Premium features plus support for business applications and business data security (fax, remote desktop connectivity, file encryption, and complete shadow incremental backup). This version of Windows Vista is, as the name implies, strictly for business purposes.

    Windows Vista Enterprise

    Windows Vista Enterprise adds Microsoft’s BitLocker encryption technology to the feature set found in Windows Vista Business, but this version of Windows is only offered to businesses participating in Microsoft’s Software Assurance program.

    Windows Vista Ultimate

    This edition has everything that is included in the Home Premium and Business editions. Vista Ultimate also adds Enterprise’s BitLocker encryption technology for the computer’s hard drives, protecting the drives so that only authorized users can boot up the OS or view the files contained in the drives.

    Because of its full complement of features, Vista Ultimate is perfect for people who use the PC for fun and business in equal parts, as well as users who want to be protected from data loss and PC theft.

    Safe Password Tips for Better Computer Security

    With so many online accounts to manage, most people tend to use the same password for everything. Many also tend to use a very “easy to guess” password. These are two common “password mistakes” that cyber-thieves are looking for. One of the most important things you can do to stay safe online is to ensure your passwords remain private.

    Passwords are designed to offer protection, used as the “key” to a door that provides access to some very sensitive personal information. If this information got into the wrong hands, financial loss or identity theft could easily occur. Password theft and identity theft is more common today than ever - due to spyware, Trojans and phishing scams. Once a password has been compromised, an insurmountable amount of personal damage can occur in a matter of minutes. The more accounts your password works with, the greater the damage. For the best security, online account passwords should be different as well as difficult.

    Safe Password Tips

    • Use passwords that are at least eight characters long.
    • Use a combination of upper and lower case letters, and include at least one number or special character. A “special character” is something like *, &, or -.
    • Never use your email password for anything other than your email account. Make sure all bank and credit card account passwords are different from each other.
    • Never use your name, birth date or social security number in a password. Change your passwords from time to time, especially bank account passwords. Never store passwords in a common document file (Excel, Word, Notepad, etc…) that is not protected by encryption.

    Password Management

    Most people tend not to use difficult and/or varied passwords, because password management can be a tedious and time consuming task. When we’re paying bills or shopping online, we want easy and instant access to our account so we can complete our tasks. It’s frustrating to get “bad password” error messages, and it’s a hassle to answer challenge questions in order to request a password reset. Because it’s nearly impossible to follow safe password practices without writing down all our passwords, the only way to securely manage passwords is to use some type of password management software.

    There are two good options here, and both are easy and inexpensive. The easiest thing to do is to utilize file encryption software to protect the document that has the passwords stored on it. For this, I recommend something like Absolute Password Protector by Last Bit Software. They have a free trial version you can download to see how you like it. This software uses strong 128 bit encryption to securely encrypt any file you have stored on your computer – making it easy for you to access but very difficult for a thief to utilize. With this software, you can store all your passwords in a Word, Excel or text file and then encrypt that file to keep it secure.

    Another good way to manage passwords is to use an encrypted database to store all of your password information. I use Passwords Plus by DataViz. This is designed to be used on a PDA, but I use it on my computer. Passwords Plus is easy and convenient, but the downside is you have to set up the database by keying in all your accounts and passwords. Both of these methods of password management cost around $29, and it is well worth it. Unlike a lot of software that requires a subscription to keep it functioning, password management software is a “one time” purchase.

    Practicing Good Computer Security Habits Will Help Keep You Safe Online

    Maintaining "difficult to guess" passwords is just one very important thing you can do to keep yourself safe online. There are many more things you can (and should) do to protect your computer and your data from cyber-thieves and malicious software. A few things to keep in mind are to use a good antivirus and anti-spyware software product, avoid downloading and installing "free" software (it usually contains spyware and/or adware) and never click links in emails that appear to come from a financial institution.

    Data Protection - Why You Need Data Protection

    You are simply fooling yourself if you believe the information on your computer belongs to you only. Unless you have some top of the line data protection programming on your computer system though other people can be looking at your files. This can be scary if you have any files on your computer that you don’t want others to see.

    This can be your bank account, passwords you use to access your online accounts, and possibly some piracy you have engaged in for movies or music. Too many of us are comfortable thinking that since our computer is in our home it is safe from others accessing it.

    With a quality data protection software program you have the lock to keep your computer files secret. There are two different types of data protection programs you can choose from. One of them prevents outsiders from being able to access your computer files. This type of data protection software includes a firewall that hackers can’t penetrate. They also protect your passwords.

    These are great ways to ensure data protection but remember that hackers are pretty smart. They have sophisticated software too. To make sure your information can’t be compromised go for a data protection program that offers high tech encrypting. If you have the Windows Vista operating system then you will find these encrypting algorithms already in available to you. Otherwise you can buy a quality data protection software program from a retailer or a computer store.

    The problem of identity theft is out of control these days, and the majority of it is taking place online. Hackers have found ways to get into a person’s system and before they know what happened their bank accounts are empty and their credit cards are maxed out. The person who hacked into the account is very rarely caught so many criminals think this is a safe way to make money fast. Don’t let your personal information be easily accessible so that you become their next victim.

    With the right data protection system in place you can breath easier about the transactions you do online. The internet offers us plenty of convenience but don’t fool yourself into thinking all of your information is safe because no one has physical access to your computer.
