...University of Sunderland School of Computing and Technology File Management System in Linux CUI Interface A Project Dissertation submitted in partial fulfillment of the Regulations governing the award of the degree of BA in Computer Studies, University of Sunderland 2006 I. Abstract This dissertation details a project to design and produce a prototype Linux character environment file manipulation assisting application. The application is offering a friendly menu driven interface to handle the jobs that non-programmers keep finding cumbersome to master when it comes to working in a Unix/Linux interface, resulting in serious mistakes and much loss of productive time. The Linux File Management System is a basic program for every user at a Unix/Linux terminal. Advantages here include the fact that the support team does not have to be burdened with solving simple file based queries by the employees. The areas of Designing GUI interfaces in Linux and Windows versus Linux Security were researched and a prototype has been designed, developed and tested. An evaluation of the overall success of the project has been conducted and recommendations for future work are also given. Words II.

...Updating Android operating system, is it really safe? All Android devices at risk of being hacked when installing OS system updates _ Pileup Flaws By Raunak Chatterjee and Anisha Agarwal Student of Computer Science and Engineering department of Calcutta Institute of Technology Email: rnk.chatterjee.cit@gmail.com ------------------------------------------------- Anishaagarwal1992@gmail.com Abstract: Android is a Linux based operating system. Initially developed by Android, Inc., which Google backed financially and later bought in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance—a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first publicly available smartphone running Android, the HTC Dream, was released on October 22, 2008. Android's source code is released by Google under the Apache License; this permissive licensing allows the software to be freely modified and distributed by device manufacturers, wireless carriers and enthusiast developers. As of July 2013, Android has the largest number of applications, available for download in Google Play store which has had over 1 million apps published, and over 50 billion downloads. A developer survey conducted in April–May 2013 found that Android is the most used platform among developers: it is used by 71% of the mobile developers’ population.

Personal, government, and business applications continue to multiply on the Internet, with immediate benefits to end users. However, these network-based applications and services can pose security risks to individuals and to the information resources of companies and governments. Information is an asset that must be protected. Without adequate network security, many individuals, businesses, and governments risk losing that asset. Network security is the process by which digital information assets are protected. The goals of network security are as follows: ■ ■ ■ Protect confidentiality Maintain integrity Ensure availability With this in mind, it is imperative that all networks be protected...

...Installing Cobbler Introduction This post will show you step by step installation of Cobbler, please comment if you think anything’s is missing as you know nothing is perfect, so my blog This topic focus on CentOS/RHEL/Fedora, if everything goes well here you should be able to build client servers without any manual work using PXE boot. Server setup. For the cobbler server basic requirement is you need two NIC cards if you want to use it for DHCP as well. Why do i need two NIC cards because it allow client servers to initially boot up in the private network where Cobbler will handle the installation. Since Cobbler utilizes DHCP and TFTP, making these services listen on a Private network will ensure that they don’t interfere with any other DHCP or TFTP server on the Public network. Once the installation has finished, the client can be moved to the Public network. Installation media You can use any media you want. You can burn iso to DVD of CentOS 5 or 6 or Fedora. Network selection. For the Network Configuration, I renamed System eth0 and System eth1 to Public andPrivate respectively. I configured each NIC with static information and made sure to check theConnect Automatically checkbox for each — otherwise NetworkManager will not bring the NICs up. Package Selection For this section either you can rely on kickstart file which will have all packages listed in a tab called %packages or you can have minimal install like “Server”.

...Installation Guidelines GRUB/LILO GRUB is the boot loader of choice for RedHat installations; however LILO may always be used in the case of most flavors of LINUX. GRUB/LILO can receive many different kernel level commands and it poses a major security risk if an attacker is able to compromise the kernel. In response you can make sure that only authorized users are able to perform those commands by password protecting during the installation process. If using GRUB, the password is by default stored as clear text, and so you will want modify the /etc/grub.conf file to store the password in an MD5 checksum. $ /sbin/grub–md5–crypt Password: (at the prompt enter the GRUB password you created at installation and press enter) $ #%t%661GFGftffgctTFTDd (This is the MD5 hash) edit the grub.conf file and replace the clear text password with the MD5 Hash. You must use the –MD5 option or the password will be stored as the MD5 Hash and not the encrypted password. Password – md5 $1$m0tLR/ $#%t%661GFGftffgctTFTDd Partitioning Partitioning correctly will help to mitigate against one specific type of denial of service. For example and attack designed to fill up a /tmp or spool directory. If your files are on the same partition as the directory under attack, your system could be rendered unusable. One should use a partition strategy where those directories that are most likely to be filled by an attacker. Typically this is /var and /home . If you are using a server for ftp or e–mail, you...

I would like to thank my supervisor Dr Hatem Ahriz for his guidance throughout the writing of this report. I would like to thank Richboy and Ete Akumagba for their guidance and for proof reading this report. I would like to thank my family for their support and love. ii Abstract This era of explosive usage of networks have seen the rise of several opportunities and possibilities in the IT sector. Unfortunately, cybercrime is also on the rise with several forms of attack including, but not limited to botnet attacks. A Botnet can simply be seen as a network of compromised set of systems that can be controlled by an attacker. These systems are able to take malicious actions as needed by the attacker without the consent of the device owner and can cause havoc. This paper is the first part of a two-part report and discusses on several reportedly known botnets and describes how they work and their mode of infection. Several historic attacks and the reported damage have been given to give a good picture and raise the bar on the capabilities of botnets. Several existing tools have been considered and examined which are useful for detecting and terminating botnets. You would find that each tool has its own detection strategy, which may have an advantage on some end than others. iii Table of Contents Declaration ................
