Cloud Computing – Is It Secure?

On-premises computing is the classic kind of computing in which you or your corporation personal and handle your personal systems. All the applications you use, as effectively as your information files, are in your personal computer systems on your personal premises either on person PCs or on an in-home regional area network.

In cloud computing, by contrast, your applications and files are held remotely on the World-wide-web (in cyberspace) in a network of servers which is operated by a third celebration. You access applications and operate on your files from your Computer basically by logging on to the network.

Cloud services are supplied by cloud-hosting providers, firms such as Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure, and so on.

There is absolutely nothing fundamentally new about the concept of cloud services. If you are applying Gmail, Hotmail or yahoo for your emails, you are employing cloud services and likely have been for years.

What is fairly new is the kinds of services that are getting supplied in a cloud-environment. These now go far beyond email to cover all the IT solutions that an on-premises computing environment would deliver, such as accounting, marketing and advertising, human sources and so on.

Positive aspects of cloud computing

Cloud computing has many advantages over on-premises computing:

1) You can run an application or access your files from anywhere in the world utilizing any personal computer.

2) Cloud computing is more affordable.

three) You need to have significantly less technical knowledge.

4) Cloud computing delivers a improved overall performance.

five) Cloud computing is eminently scalable. Growing the quantity of applications you use or the quantity of information you shop does not need a heavy investment you only require to advise the cloud-hosting adviser.

Offered these advantages it no surprise that over the last couple of years there has been a widespread speedy adoption of cloud computing. Analysts estimate that the development rate of all spending on cloud IT will soon be at least 4 occasions more rapidly than the growth rate of all spending on on-premises computing.

Indeed, analysts are expecting the annual growth price of spending on cloud computing to average 23.5% compound from now till 2017. In addition, by that year spending on cloud services will in all probability account for one-sixth of all spending on IT items, such as applications, program infrastructure computer software, and standard storage.

Offered the rapid growth in cloud computing, the huge question, of course, is irrespective of whether cloud computing is secure. Is it far more or much less secure than on-premises computing?

The short answer is that cloud computing is not less safe than on-premises computing. Having said that, the threats are somewhat diverse in nature, although they are converging.


Normally speaking, there are six major threats to laptop or computer safety. These are:

Malware – is malicious software such as viruses, trojans, worms, spyware and zombies. Malware is installed on either a Computer in your residence-workplace or a cloud-computing server. Where Blockchain handle of a network of computers to a malicious group (eg, to send spam) it is known as a botnet.

Net app attack – is an attack in which web-based applications are targeted. It is a single of the most common forms of attack on the World-wide-web.

Brute force attack – operates by attempting all achievable combinations of letters or numbers in order to find out a cipher or secret key. For example, you could crack a password by repeatedly attempting to guess it. Modern computing energy and speed makes brute force a viable kind of attack.

Recon – is reconnaissance activity that is utilised to choose victims that are both vulnerable and important.

Vulnerability scan – is an exploit applying a unique program to access weaknesses in computers, systems, networks or applications in order to create information for organizing an attack.

App attack – is an attack against an application or service that is not running on the internet, ie the plan will be on a laptop or computer somewhere.


A honeypot is a decoy web page, network, system or application that has been intentionally made to be vulnerable to attack. Its purpose is to gather details about attackers and how they perform.

Honeypots let researchers to:

collect information on new and emerging malware and establish trends in threats
identify the sources of attacks including information of their IP addresses
ascertain how attacks takes location and how finest to counteract them
determine attack signatures (pieces of code that are exclusive to unique pieces of malware) so that anti-virus application can recognise them
create defences against certain threats
Honeypots have proved to be invaluable in erecting defences against hackers.

The Spring 2014 Cloud Security Report

Alert Logic offers security services for both on-premises and cloud pc systems. The corporation began issuing cloud safety reports in 2012. Its Spring 2014 Cloud Security Report covers the year ending 30th September 2013.

This report is based on a combination of real-planet security incidents experienced by Alert Logic’s customers and data gathered from a series of honeypots the firm set up about the planet.

The report throws some exciting light of the safety of on-premises and cloud computing relating to the company’s prospects. Here are some of the highlights:

[1] Computing is shifting much more and extra from on-premises to cloud-primarily based computing and the kinds of attacks that target on-premises systems are now targeting cloud environments. This is possibly due to the escalating worth of prospective victims in the cloud.

[two] While attacks on cloud environments are rising in frequency, the cloud is not inherently significantly less secure than conventional on-premises computing.

[3] The frequency of attacks in both on-premises and cloud computing has enhanced for most types of threats, even though for a few varieties of threats it has fallen. Right here are the principal points of comparison between each computing environments:

The most prevalent sorts of attacks against on-premises buyers had been malware attacks (which includes botnets) at 56% in the course of the six months ending 30th September. At only 11%, these attacks have been significantly less frequent among cloud buyers. However the quantity of cloud buyers experiencing these attacks is rising promptly, much more than doubling in one particular year.

Attacks employing brute force elevated from 30% to 44% of cloud shoppers but remained stable in on-premises environments at a high 49%. Vulnerability scans jumped significantly in each environments. Brute force attacks and vulnerability scans are now occurring at practically the identical prices in on-premises and cloud environments.

Web app attacks are much more likely amongst cloud shoppers. Nevertheless these attacks are down year-on-yea
