Antivirus software for Ubuntu

Actually there aren’t so many options available in choosing right antivirus software(in comparison to other applications) on Ubuntu 9.10 or 10.04 because Linux based operating system is not vulnerable to the most of the viruses and  *wares(Due to the Fact that,Some years ago,only windows XP or other windows NT based operating system were suitable for common users so crackers and virus programmers had busy in creating viruses for windows OS. Another reason is that Linux based operating systems are much secure than windows).

But know things has changed and now Ubuntu 10.04 Lucid Lynx is becoming popular among common desktop users(for Home use as well as professional purposes due to the benefits of Open Source tools). That’s why It is a good idea to use antivirus tools in Ubuntu 10.04.Some Common and most recommended antivirus software for Ubuntu 10.04 is ClamAV and Avast.

Update!

Anyway, I don’t prefer to use any antivirus softwares on Ubuntu Linux based operating systems such as Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) or Linux Mint or Fedora… If you really want to secure yourself from cyber threats then first secure yourself on the Internet. Here are some good recommendation for a beginner :

  • Use strong passwords (Learn how to make strong passwords)
  • Always type url in the browser e.g http://www.amazon.com
  • check https (secure padlock) in the address bar before entering any confidential information on any website
  • Use Logout for closing a session

How to Make Strong Passwords

how to make strong password

The aim of this post is to help you in making your passwords(E-mail,Bank Account,Paypal,Alertpay or others password) strong to assure high security.

What is Password?

Password is an authentication mechanism which is required to use the system’s resource or to login.Authentication need two types of information – first one is username or e-mail ID which is public and second one is password,which is private i.e only known to the claimant.The passwords can be divided into two types – One time Password and Fixed Password.Here we will discuss about fixed password,which should be changed/rotate frequently.Since most of the system use the password authentication mechanism so the password must be strong.

Common Mistakes you must avoid in selecting passwords

1.Using mobile or phone number or any other number(which is declared as public i.e every body can figure out very easily through a little research online(by using Google) or offline) as password.
2.Number of Characters less than 8 .
3.Simple combination of numbers or characters like 1234,12345,asdf,qwer,zxcv,09876,lkjh,poiu,etc.
4.Same as username or to put name in field of password.
5.One password for all the accounts.
6.Writing password in a page or Diary.

Points to remember in making good and strong passwords
1.It should include Alphabate(Both Upper case and Lower case),Numbers(0,2,6..) and special Characters(*,@,),{,%,$,#…).
2.Number of characters should be as long as you can remember,in general minimum of 12 characters are recommended.
3.Try to Remember it(Don’t write anywhere and never share with anyone).If you have any problem in remembering long password or you are managing a lot of password then you can also take help of Some Encryption Software.Using the cryptography techniques you will have to remember only one strong password(Commonly known as master password) and it will encrypt all others passwords in to a file.Since it is encrypted so if anyone get those file then also he/she will not be able to recover your passwords from those encrypted files.Trucrypt and Gnupg are two great encryption tools for Ubuntu 10.04 that can be used to perform various cryptography actions like file encryption,disk encryption,e-mail encryption etc.
4.Frequently change or rotate your passwords between different accounts.

How to remember lot of passwords
Remembering lot of passwords is actually very simple.First make a strong password and then rotate or change some digits to make another password for another accounts and so on.
Password1(For Account1) : )qZl2&1#it?6A&e //15 characters
Password2(For Account2) : )rXm2&1#it?6A&F //Notice The Change : 1st and 3rd character : shifted up in a-z.
password3(For Account3) : )sWn2&1#it?6A&g
password4(For Account4) : )tUo2&1#it?6A&H
……………………………………and so on.

Algorithm for above password generation
1.Shift up by one position the second and fourth characters in a-z.
2.3rd character is shifted back by two position in a-z.
3.Last(15th) character is shifted up by one position and case is inverted(i.e from lower to upper and upper to lower).
4.All the other characters remains same(you can also apply some more concepts on these characters to make the password more strong).

So you can design this type of simple algorithm(It will hardly take 3-5 minutes) for generating lot of strong password and it will be easier to remember but keep the algorithm strictly private.

That’s ALL …End of the Password Fun!
