Ubuntu Boot Camp 2013The Freedom Is Yours!!

Introduction

Who am I???

No Cell phones please...put them on vibrate & answer outside

Lunch at 12-12:45 try to be on time

Feel free to join the discussion....but please for the benefit of others in

the group no side conversations while I'm presenting..Thanks

Please ask me to clarify a point, if perhaps I'm speaking too fast

And if I don't have the answer just now, I will do my level best to find it

by the next day!!

Freedom to choose what operating system you install

Freedom From Licensing costs (or related piracy)

Freedom from Hardware Device Drivers

Freedom From Viruses (& Anti Virus programs)

Freedom from Trial Versions of Software

Ubuntu Boot Camp 2013Ubuntu Is..........

Ubuntu Is .....Beautiful, Secure, Fast & CompatibleTo use Ubuntu is to fall in love with it...whether it is on your desktop, laptop, tablet

or phone. You can work quickly to accomplish all that you can imagine!

Ubuntu was first developed in South Africa but now has contributors from around

the globe.

Ubuntu is an African word meaning “humanity to others”. It also means “I am what I

am because of who we all are” This lends itself to the community spirit behind

Ubuntu and the promise that it is free and always will be free to use, share and

develop.

Affordable & High Quality

Freedom to run, study, redistribute and improve

Development of Local ICT Industry

Ubuntu Operating System

Free of licensing charges

Same version & features for professional & home users

Locked Administrator user Root -therefore rarely targeted by viruses

User data stored only in home folder, easy to back up or migrate

No need to search for hardware drivers...truly plug and play

Charges per user license (if you have bought a new computer, you paid)

Separate Professional & Home editions Pro has more security features

Enables easy access to administrative user & regularly targeted by viruses

User data saved in multiple locations, hard to backup or restore

Ubuntu Boot Camp 2013Key Differences Between Ubuntu & Windows

Microsoft Windows Operating System

Ubuntu Boot Camp 2013Discussion...

Preloaded by OEM (original equipment manufacturers)

Broke into the market with win95 as they developed an effective GUI (graphical user interface)

Ubuntu's first release was in 2004...late to the game?

However Linux has been around since 1994 and supported by large companies such as IBM & Sun Microsystems

Previously Linux based OS's were seen as too difficult for the average user

Is MS Windows a better product?

Why Does Microsoft have market dominance

Ubuntu Boot Camp 2013Drawbacks of Ubuntu & Windows

Ubuntu Drawbacks

Need to download the ISO & most people do not have the bandwidth

Some software such as Adobe is not compatible

Open Office file format...by default the docs are saved as .odt & not compatible with MS office

Previously there was connectivity issues with 3g modems

Windows Drawbacks

Ubuntu Drawbacks

Only installed via CD – so how do you restore your netbook?

Comes bloated with trial software (most are 90 day trials)

Requires the use of anti-virus software which slows down system

Can you contact MS directly for support?

1. Privileges

In Linux, users do not have 'administrator' access by default. No action by a virus can be allowed without

granting access or entering your sudo or root password

2. Social Engineering Viruses & worms are often spread by convincing users to do something they shouldn't...like open

attachments that may be infected. It is too easy on a Window's system to run an executable file, whereas

on a Linux system, a user would have to read the email..save the attachment..give it executable

permissions and then run the executable

3. Audience SizeThere is no doubt that Microsoft Windows still dominates most of the computing world as well so do

Outlook & Outlook Express. A virus can be targeted at Windows users, since they all use the same

technology, whereas there are many different Linux distributions such as Ubuntu, Fedora,Mint etc so

they will only reach a small fraction of users. Millions of users all using the same software is an attractive

target. “Security through obscurity”

4. How Many Eyes?The larger the group of developers and testers working on a set of code, the more likely any flaws will be caught

and fixed quickly (as happens with the community support approach) On the other hand, Windows has a limited

number of developers and they don't often tell about the problem until they've created a solution

Ubuntu Boot Camp 2013Why Is Linux More Secure Than Windows?

What Can You Do To Stay Secure?

Minimize the use of root privileges

Keep your system up to date

Enabling a firewall

There is also virus scanners for Linux

such as Clam AV

As more 'non-geek' users adopt Ubuntu or

Linux, system administrators will need to:

Examine unnecessary services running in

background

Enforce strong password policies

Minimize installed software to minimize

vulnerability.

Ubuntu Boot Camp 2013How To Stay Secure with Linux

Assessing Your Needs is Key!!

What software are you currently using now? Does it also run on the Ubuntu platform or is there an open source equivalent?

If not then you can use programs such as Wine or Virtualbox to layer it on top of Ubuntu

Also is your hardware compatible with Ubuntu? Modems, printers

Ubuntu Boot Camp 2013Ubuntu Live CD

Using The Ubuntu Live CD

Live CD....is wonderful

Allows you to test run Ubuntu checking for hardware compatibility

You can repair an installation using the Live CD

Easy to check a Windows system or flash drive for viruses

Getting Started

You can install a dual boot option and allocate disk space to each OS. As seen below..there is a side by side option

It is important to install Windows first..then Ubuntu

Ubuntu Boot Camp 2013Installing Ubuntu – Dual Boot Options

Installation Tips For Ubuntu

Setting Root password – In a default Ubuntu installation, the root account is disabled, Instead the user account created during the installation process is used with sudo (super user do) to access the administrator privileges.

Swap File With a default installation, Ubuntu creates a swap drive. It is generally 2 times the amount of RAM installed in the system...eg: 2 gb RAM = 4 gb swap file

Change the default OS at boot...if you have a dual boot system, you can choose which one is the default at boot time, to eliminate the need to choose each time

Selecting the correct country Be sure to select Tanzania, so that the updates are pulled from the local server so as reduce bandwidth usage. TZ is not in the list after installation is finished...not sure why?

Ubuntu Boot Camp 2013Installing Ubuntu – Nice To Know's

Ubuntu Boot Camp 2013Root Access – What You Need to Consider

Most Unix and Linux systems have an account or group which enables a user to exact complete control over the system, often known as a root account. If access to this account is gained by an unwanted user, this results in a complete breach of the system. A root account however is necessary for administrative purposes, and for the above security reasons the root account is seldom used for day to day purposes (the sudo program is more commonly used), so usage of the root account can be more closely monitored.

Limit logins as root user. You should use sudo to execute root level commands as and when required. sudo does greatly enhances the security of the system without sharing root password with other users and admins.

Su “do” =Super User do

Sudo allows a system administrator to the ability to run some (or all) commands as root while logging all commands & providing a clear audit trail of who did what.

Sudo uses timestamp files to implement a "ticketing" system. When a user invokes sudo and enters their password, they are granted a ticket for 5 minutes. This avoids the problem of leaving root access open when others can physically get to your keyboard.

Thank you !
