Security Assistant detects the insertion of removable media like USB drives and CDs/DVDs. It monitors any software attempting to execute from or copy to the computer from these sources. If the software is unauthorized, execution is blocked and files are quarantined. Alerts about such activities are sent to the Security Assistant management console. While data files can be accessed normally, writing software to removable drives can be disabled as needed for additional security. Security Assistant provides control over removable media without preventing all use of ports by maintenance staff.
This presentation lists out the types of malwares as well as describes them in a well structured way. Topics such as 'Safety measures' and 'damages caused by malwares' are also included.

Anthony Merseal - Steps to Keep Your Computer Virus Free Anthony Merseal
Here you will be able to find the various tips and tricks which will provide help to protect your device from threats and keep your computer virus free.
Designed largely for management, this presentation discusses common vulnerabilities, cyber security attack trends, and how to hamper, thwart and contain malicious attacks. Included is data from the latest vulnerability trend research, cyber security threat data, and a variety of methods for staying safe, detecting a compromise, and handling a compromise. The goal of this presentation is to give management information and help "start a conversation" within small businesses between management and IT staff to ensure the security of organization data.

Ubuntu Boot Camp which Darlene facilitated at Costech (Commission for Science & Technology) in Dar Es Salaam Tanzania. We had a full house of enthusiastic users looking for hands on knowledge of Ubuntu & Open Source
The world of information technology and communication is moving towards standardization of hardware
ports. All kind of communication is now using USB as the port as it is universally recognized hardware
medium of data communication. It is become flexible and easy to use kind of things with portable USB
storage devices to copy data from one system to another system. It is possible to copy data within seconds
with the help of portable USB flash memory devices. It has leaded insecurity of data storage on computer
system. Various surveys has shown after network copy only USB data copy has made data insecure on
computer . It is also the source of malwares in the system. To disable the USB ports is not the solution to
this problem because almost all peripheral devices now uses the USB ports for communication. So, we have
implemented a system which has complete USB storage enable and disable control for Linux operating
system. The administrator will decide the storage devices connected to USB must be enabled or disabled .
We experimented the algorithm on Linux kernel version 3.11 onwards on Debian based linux distributions.
We have got 100% success rate of the said system with zero percent performance degradation.

As a system administrator who is responsible for your company-'s netwo.docxbickerstaffinell
As a system administrator who is responsible for your company\'s network, you understand that operating systems (OS) are various. Discuss the following queries:
Why are there so many versions of OS?
What are the features that make them different?
Explain the pros and cons of each.
Part II
Familiarize yourself with the historical evolution of OS. Select 2, and then talk about them in terms of various aspects (e.g., encryption, size, speed, memory, video, and security). Respond to the following 2-part question:
How can the evolution of OS (1) benefit an organization and (2) cause harm to an organization?
Has to be 400-600 words
Solution
There are many versions of Operating systems because each operating systems has unique features and they support different features as per hardware available.
For adminstrative purposes linux environment is better, since we can use the features through many commands. For normal web projects purpose MAC or windows operating systems
are better than linux envornment.
Linux has more features which is mostly important is security. Its genuine virus free and we can make permissions to folders or files using simplr commands.
We can manage networks to all types or levels of users using windows environment. For application developement like mac apps.. we use apple software which
is smooth to use and it is virus free. Till now no one case registered against mac os regarding virus attacks.
Linux is powerfull os where it advantageous when dealing with commands and managing networks. But is is poor in GUI Interface.
Windows OS is good at GUI and easy to install and use where cons is, it ismore prone to security attacks.
MAC OS is good to develop apps and programming but cons is, it wont readuly accept to migrate or open projects in another OS environment.
PART-||
Earlier in 1954 time, Fortran os is developed.. this is done using fortran language.
Later this was modified to support single stream batch processing. input/output routines, recovery to clean up.
Then later supporting mouse to system, time sharing system, ethernet, audio, video, later supporting more security, speed while booting etc.. are added.
Now Linux, windows, MAC , Android OS are mostly using OS world wide.
Benift to organization to manage all data simply using GUI or simple commands. But same time it can cause harm.. since it is machine programming, we cannot trust always it is safe. We must take several security measures.

1. Controlling USB Drives
And Other Removable Media
Recent news of the Stuxnet Trojan attacking Siemens systems used to control critical infrastructure and
industrial plants reminds of the necessity to control the use of USB drives and other removable media
or be prepared to accept a continuing stream of malware infections. Fortunately for users of Naknan's
Security Assistant, we've got you covered.
Security Assistant detects the insertion of USB drives and CD-ROM/DVD, as well as plug-in
removable media. Upon detection, Security Assistant immediately sends an alert to the Management
Console but does nothing else unless something on the media attempts to execute or move to the
computer. This could be a worm, Trojan, or other malicious software exploiting Microsoft's autoplay
feature, or it could be the computer user attempting to install or execute unauthorized software, such as
LimeWire. When software attempts to execute from removable media, Security Assistant intervenes
until it determines whether the software is authorized to execute from that location. If not, execution is
blocked and the software is quarantined (it disappears from the media) unless it is write-protected. If
the software is attempting to move from removable media to the computer, like a drag-and-drop or
other file copy, the software is checked to determine whether it is authorized to exist on the computer.
If not, the file copy that moved to the computer is quarantined but the source copy is ignored. In all
cases, alerts to the Security Assistant Management Console let the Security Assistant operator know
what is happening.
Security Assistant monitors only the movement or execution of software, not data files. So, any data
file, such as a Word document or Excel spreadsheet, can be opened without interference.
At present, any file can be written to the USB drive, since doing so does not present a software-based
security threat. For customers who wish to disable the ability to write to writable removable media,
Security Assistant provides that capability. For USB drives, this is easy, quick, and reliable. For
preventing writes to CD/DVD, it can be less straightforward when third party DVD burning software is
installed on the computer. It can still be done, it just requires a couple more steps to remove the third
party “burn” capability from the computer's whitelist.
It is possible to provide more options with respect to removable media, and some of those will be
coming in the first half of 2011. It's important to remember that we don't rename the USB driver, which
prevents everyone from using the USB ports (maintenance techs wouldn't like that, since they often
carry several tools on USB drives). USB drives are great conveniences, but if you're going to be secure,
you must control them; Security Assistant can give you that control.
