Though these benefits are valuable, the security issues must be understood by every organization before it embraces the new technology of cloud computing and allow its wide spread. Without addressing the security compliance issues, the rewards of loud computing cannot be fully realized. Here in this post we list the top threats of clout computing that are quite common in all cloud providers. Keeping these threats in mind, customers must evaluate cloud infrastructure vendors on more than price and top feature sets before deciding to move critical systems and applications.

cloud-computing

Recommended Reading:

1. Illicit Cloud Use and Common Platform Attacks

This category of threat includes illegal use of a cloud provider’s infrastructure to launch attacks or conduct illegal activity on the Internet. For instance, the cloud might be used to attack or abuse other users within the same cloud infrastructure by leveraging common address spaces, common networks or hardware to assist in the attack.

2. Insecure Cloud Application Programming
Interface Access

This category of threat includes the relative insecurity of cloud application programming interface (API) frameworks. The insecurity could also be in the operations that might be performed programmatically to manage cloud-based systems. Often the security controls, authentication and authorization mechanisms provided, lack the ability to prevent authentication bypass attacks and API hacks. This weakness may allow unauthorized access to privileged functions or operations.

3. Malicious Insiders

This category of threat is perhaps the most dangerous of all threats to cloud computing. The insider threat can also be the most difficult to prevent. In cloud computing, this threat carries disastrous implications because large segments of a customer’s infrastructure can be at risk while under the control of another party. Many cloud providers lack transparency about hiring practices, screening and background investigation processes. Getting a job at an Internet service provider (ISP) or SaaS provider, with ill intent, might be easier than many believe. Compounding this threat is the inability of cloud providers to monitor access to critical systems once an employee is granted privileged access to the infrastructure.

4. Shared Infrastructure

This category of thread is due to the sharing the cloud provider’s infrastructures across hundreds of customers though the cloud computing was never designed to operate in such a massive multitenant mode. Often, basic protections and customer compartmentalization is lacking in the cloud stack causing vulnerability in cloud infrastructure at all levels of the stack right from hardware, hypervisor, network, operating system to storage and also application layers.

5. Data Theft and Loss

Data is the lifeblood of most organizations. It has a high value and consequently is the target of many attacks. Preventing unauthorized access to cloud-based data is a top priority in cloud security. However, many cloud providers do not adequately protect customer data-at-rest. Data theft is but one type of risk that cloud providers must adequately address in their cloud implementations. Another risk is data loss, which carries equally severe impacts. Storage might be corrupted; drives might fail; and partitions could accidentally be deleted. Also, the cloud provider might lack adequate backup capability.

6. Account Hijacking

Phishing, pharming and email-based attacks designed to direct users to a fraudulent website with the goal of stealing their user names and passwords are a constant threat. Once the users’ credentials are obtained, the attacker can access customer accounts, change data and misdirect customers to other fraudulent sites. A company’s cloud-based infrastructure could actually be used as a staging ground for new attacks — all executed
under the company identity.

Software tools can not always recover lost data. Please read our post on how to backup your computer (disks). You can even take a backup on a cloud storage which is reliable too. Read How to backup your files using online backup services.

Bootable Live Disks

Linux Live CD/DVD (such as Knoppix/Ubuntu Live) – When the Hard Drive is non functioning, your system will not boot. If you have stored or want to access files that are there on the drive, the first thing to do is, boot your computer using Live CD/DVD distributed by Linux (Knoppix or any other Live OS CD). Live CD/DVD can boot your computer via CD/DVD and installing RAMDISK image (on RAM of course). Advantage here is, Live CD/DVD can mount your internal Hard Drive and you could explore files that are recoverable. This is really helpful and we have used this technique in the past with great success.

Hard Drive Consistency Checkers

If your Hard Drive is able to boot but you feel or see some disk related errors, it would be worthwhile to run Disk consistency checking software such as;

CHKDSK – A DOS/Windows utility that can find disk errors and fix.

Disk Utility – A Disk related tool for MAC OS X that can verify the integrity of the Disk.

fsck – a Disk consistency checker for the UNIX.

These software tools are capable of finding disk errors and possibly fix them. But, it should be noted that not all errors can be fixed by these tools, they are not miracle tools anyways :)

Data Files Recovery

Sometimes we accidentally delete important files only to regret later. Fortunately there are some free data recovery tools that can just undo deleted files.

Recuva recovers files deleted from your Windows computer, Recycle Bin, digital camera card, or MP3 player.

PhotoRec is another such tool.

Data Forensics

After a break-in or seizure of computer systems or disks, forensic analysis can happen on the disk to understand the data or recover data from the disk. There are tools that can perform forensic analysis of the recovered disk from criminals etc.

The Coroner’s Toolkit (TCT) - TCT is a collection of programs by Dan Farmer and Wietse Venema for a post-mortem analysis of a UNIX system.

Forensic Toolkit (Commercial) -  Data forensic software created by AccessData.

EnCase (Commercial) – Disk security and recovery experts.

This is not necessarily true. Project manager are like small business owners and they need to know every aspect of  management. The general management skills are the foundation of a good project management practice.

Project_Manager

Recommended Reading:

Here in this post we look at eight essential skills that every project manager must possess. Your mastery of them or lack of them is likely to affect the project outcome.

1. Communication Skills

One of the most important skill needed for every project manager is excellent communication skill. Project manager should ensure that project related communications are explicit, clear and complete to the audience. Just one miscommunication has a potential to derail the project.

2. Organizational Skills

Project manager have project documentations. minutes of meetings, project reports etc. They need to organize information well,organize meetings, put together teams and at times also organize media release schedules depending on the project.

3. Planning Skills

In order to stay organized, planning skills are very important. Project manager needs to plan the delivery milestones, plan meetings with clients, management teams etc. Planning skills go hand in hand with organizational skills and is one of the most important skill needed in addition to communication skills.

4. Budgeting Skills

As the project manager needs to manage the project in a given budget, his knowledge of finance and accounting principles are important. Essential skill is the ability to perform cost estimates for the project budgeting. Right from hiring cost, resourcing cost to apex cost, the project manager needs to budget them appropriately so the project does not over run the budget.

5. Conflict Management Skills

There are no projects without problems. Conflict management is resolving problems. It could be conflicts between team members or conflicts for some resource. The project manager should be able to clearly separate out the problems from cause and analyze the problem, the situation causing it etc and implement the best course of action.

6. Negotiation Skills

The negotiation starts at every stage of the project right from the beginning. Negotiation skill is essential as the project manager needs to negotiate various aspect like scope of the project, the schedule, cost, team structure that is needed to deliver the project, milestones and many other things that happen through out the project

7. Influencing Skills

Influencing skills go hand in hand with negotiation skills. Influencing is convincing the other party on the choice that project manager thinks is better than the other. Influencing requires an understanding of the formal and informal structure of all organization involved in the project.

8. Leadership Skills

Not all project managers turn out to be a good leader. But a project manager who has good leadership skills can impart vision, gain consensus for strategic goals, establish direction and inspire and motivate the team. Project manager must exhibit the characteristics of a leadership during different times in the project.

OpenStack Compute is software for automatically creating and managing large groups of virtual private servers. OpenStack Storage is software for creating redundant, scalable object storage using clusters of commodity servers to store terabytes or even petabytes of data. This is a great effort by Rackspace which let you have your own cloud platform, incase you are not comfortable with the external cloud.

Break Free From Proprietary Lock-In

Absolutely free to download with Apache 2.0 license, OpenStack is truly open and takes changes from the community. A great way to have open and transparent software for the cloud geeks. The Open Source model removes the fear of proprietary lock-in for cloud customers.

Supported By Rackspace, NASA, Dell, Citrix and Many More

Rackspace and NASA have donated their source code to have this Open Cloud project going. RackSpace running the project with its donated code that powers its Cloud Servers to the OpenStack project. The project also has the technology from the Nebula Cloud Platform developed by NASA. There are many like Dell, Citrix, Intel, AMD etc who are supporting this initiative. Needless to say, the project is going to get lot of attention now.

Recetly Released

OpenStack was announced July 19th, 2010. Many components of OpenStack have been commercially used for years and now these technologies are released as open source software. Early code is now available on LaunchPad, with an initial release for OpenStack Storage expected in mid-September and an initial release for OpenStack Compute expected in mid-October.
