Clonezilla Server Edition Installation on Ubuntu

clonezilla-logo

The tutorial describes installation steps for Clonezilla Server Edition (SE) on Ubuntu 16.04.1 LTS using a Bash script. Clonezilla is OpenSource Cloning System (OCS) and it is a partition and disk imaging/cloning program . It helps you to do system deployment, bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition).

Clonezilla live is suitable for single machine backup and restore. Clonezilla SE is for massive deployment because it can clone many computers simultaneously. Clonezilla saves and restores only used blocks in the hard disk. It decreases time and saves the hard disk space and increases the clone efficiency.

Clonezilla is a part of DRBL (Diskless Remote Boot in Linux) which provides a diskless environment for client machines. Therefore we need to install and configure DRBL server first. I created DRBL deployment script deploy_drbl.sh that helps you to install DRBL and configure server on Ubuntu with a single Ethernet card. You have to provide only the name of Ethernet interface and the script creates virtual interface for you based on your physical interface. It also downloads a DRBL project public key, download and install drbl package from repository. The script starts interactive Bash and Perl scripts that come with Continue reading

Meet MailSniper, a tool to search Microsoft Exchange emails for sensitive info

Meet MailSniper, a new pen tester tool that may be of interest to you if you need to find sensitive data such as passwords, credit card numbers and healthcare data, or need to access databases, or even to discover insider and network architecture information.MailSniper is a penetration testing tool, written in PowerShell, to allow for mass searching through email across every mailbox of an organization’s Microsoft Exchange environment.Beau Bullock, from the penetration testing firm Black Hills Information Security, cited a 2016 Mandiant M-Trends Report (pdf) which claimed organizations are compromised an average of 146 days before detecting a breach. That long of a window gives attackers plenty of time to locate, compromise and exfiltrate sensitive data; pen testers, however, may only have a window of five days or less to do the same thing in order to prove risk to an organization.To read this article in full or to leave a comment, please click here

How to implement an effective BYOD policy

Concerns around BYOD once revolved around security with third-party services, but that's getting easier to manage, says Fred Ouawad, founder and CEO of TaskWorld, a company focused on employee performance and management. Now businesses are finding it more difficult to govern BYOD policies internally.Businesses are more focused on internal security. For example, if an employee doesn't perform regular updates on their smartphone, it can pose a risk to the business says Mouawad."At the moment, pushback mostly comes from highly regulated industries like banking and government agencies. But even they are slowly realizing that BYOD is something that can't be resisted," he says.To read this article in full or to leave a comment, please click here

IDG Contributor Network: The Emergency Alert System: Failure IS an option

Even a failed result can be a successful test If you live in the United States, it's likely that you've fallen asleep with the television on only to be woken in the middle of the night by shrill tones blaring from your television set, followed by a deep baritone voice letting you know that there is no active nuclear attack or alert and what you experienced was only a test. The Emergency Alert System (EAS) was designed as a tiered distribution mechanism, very much like a pyramid, with the President of the United States positioned at the pinnacle. As you move down the tiers of the pyramid, you become more regionalized and localized in the coverage area that is served. Using this logic, any participating station in the chain can initiate an emergency alert message, and by default, the information will trickle down to the lower tiers as stations monitor the tier above them. To read this article in full or to leave a comment, please click here

Verizon’s shift into digital media is much bigger than Yahoo’s data breach

Yahoo will recover from the latest news about its email data breach that happened in 2014. Looming much larger than the breach is the post-merger challenge Yahoo faces as part of Verizon. It is what Richard Windsor of Radio Free Mobile calls the irrelevant challenge. Can Yahoo’s assets pose a relevant challenge to Google, Facebook and other digital media companies after the merger?+ Also on Network World: A requiem for Yahoo +In the mobile-first world, Yahoo repeatedly missed the opportunity to convert its fixed internet users to mobile. Windsor suspects that most of Yahoo’s 600 million mobile monthly active users (MAU) are Yahoo email users. Though this sized audience is not insignificant, Yahoo does not have relevant mobile engagement with multiple mobile apps. How can post-merger Verizon, Yahoo and AOL turn its billions of MAU mobile users into an ecosystem that prints money like Google with search, Gmail, Maps and Youtube and like Facebook with Facebook, Messenger, WhatsApp and Instagram?To read this article in full or to leave a comment, please click here

Here’s how Microsoft is using containerization to protect Edge users

One of the biggest security risks for computer users is their web browser. According to Microsoft, 90 percent of phishing emails use the browser to initiate attacks, which can then be used to help attackers establish a beachhead inside a company. Microsoft is aiming to better protect users and organizations from the threats that they face with a new feature called Windows Defender Application Guard. It's designed to isolate Microsoft Edge from the rest of the files and processes running on a user's computer and prevent computer exploits from taking hold. This is a move that could drive greater adoption of Microsoft's browser in the enterprise, at a time when the company is fiercely competing with Google in that space. Security of company assets is a big problem for enterprises, and Microsoft is offering them another way to help protect their users without requiring those users to be security experts.To read this article in full or to leave a comment, please click here

What’s in your code? Why you need a software bill of materials

Writing secure applications doesn't mean simply checking the code you've written to make sure there are no logic errors or coding mistakes. Attackers are increasingly targeting vulnerabilities in third-party libraries as part of their attacks, so you have to check the safety of all the dependencies and components, too.In manufacturing, companies create a bill of materials, listing in detail all the items included when building a product so that buyers know exactly what they're buying. Processed food packaging, for example, typically tells you what's inside so that you can make an informed buying decision.[ Also on InfoWorld: 19 open source GitHub projects for security pros. | Discover how to secure your systems with InfoWorld's Security newsletter. ] When it comes to software, untangling the code to know what libraries are in use and which dependencies exist is hard. It's a challenge most IT teams don't have the time or resources to unravel.To read this article in full or to leave a comment, please click here
