A Review Of Cloud Computing Security: Virtualization, Side-channel Attacks, And Management
In recent years cloud computing has become a growing interest for organizations looking to reduce their IT costs by offloading infrastructure and software costs onto 3rd party organizations who offer Software-as-a-Service (SaaS) (e.g. Google Apps), Platform-as-a-Service (PaaS) (e.g. Google App Engine), and Infrastructure-as-a-Service (IaaS) (e.g. Amazon EC2). However, due to the relative infancy of cloud based computing services, there exists uncertainty about the level of information security offered by these services. IaaS cloud services are largely reliant on virtualization technology, which is seen as providing all the security and process isolation a customer might want.

Ex-C.I.A. Chief Says U.S. Should Create A New Internet To Avoid Cyber Attacks
Michael Hayden, head of the CIA under former President George W. Bush, says the U.S. should create a totally new Internet infrastructure to thwart cyber attacks that increasingly plagues the current Internet.
The proposed new system, with the domain name ".secure" instead of ".com," would get rid of the anonymity protected by the privacy guarantees of the Fourth Amendment. Users would need "certified credentials" to access the .secure system, according to Nextgov.com, which monitors the use of technology in the federal government.
It would allow the federal government and financial institutions, for instance, to operate behind the secured infrastructure, while users who wish to remain anonymous could continue to use the present .com domain.
Some cyber security specialists fret that Fourth Amendment privacy rights prevent the federal government from securing its information technology as tightly as other, more restrictive countries, like China, that monitor all Internet usage in the country for both viruses and anything critical of the government.
Others are critical of the .secure idea, however, arguing that the new network will be too big to manage and will actually help hackers go after government computers, by gathering all the important information in one place.

Apple Finally Responds To Malware Attacks On Mac With Software Update (AAPL)
After legions of people fell for the MacDefender trojan trap within the past couple weeks, Apple decided to make a statement.
Its first statement was telling Geniuses and customer support representatives to keep their hands off when customers would complain.
Apple's second statement came yesterday, when it released a support document explicitly explaining how to remove the malware from your system.
The document also says, "In the coming days, Apple will deliver a Mac OS X software update that will automatically find and remove Mac Defender malware and its known variants. The update will also help protect users by providing an explicit warning if they download this malware."
If you have MacDefender, MacProtector, or MacSecurity, use these steps to remove the malware:
Removal steps (from Apple's Support Document)
- Move or close the Scan Window
- Go to the Utilities folder in the Applications folder and launch Activity Monitor
- Choose All Processes from the pop up menu in the upper right corner of the window
- Under the Process Name column, look for the name of the app and click to select it; common app names include: MacDefender, MacSecurity or MacProtector
- Click the Quit Process button in the upper left corner of the window and select Quit
- Quit Activity Monitor application
- Open the Applications folder
- Locate the app ex. MacDefender, MacSecurity, MacProtector or other name
- Drag to Trash, and empty Trash
Malware also installs a login item in your account in System Preferences. Removal of the login item is not necessary, but you can remove it by following the steps below.
- Open System Preferences, select Accounts, then Login Items
- Select the name of the app you removed in the steps above ex. MacDefender, MacSecurity, MacProtector
- Click the minus button

Gene Simmons Threatens Anonymous, Responds to DDoS Attacks Against His Site
The attack was part of Operation Payback, a campaign that over the past few weeks has been targeting organizations who legislate and litigate in support of copyright laws. Loosely organized by Anonymous, a group of Internet "vigilantes" has launched a series of denial-of-service attacks against the likes of the MPAA, the RIAA, the UK Intellectual Property Office, as well as against the KISS bassman.
Sponsor
The direct action campaign has effectively shut down sites that have been most vocal (and litigious) about their pro-copyright and anti-piracy stances. It has also targeted law offices that have been deemed to be part of a what TorrentFreak has called "pay-up-or-else" schemes, threats of legal action aimed at alleged file-sharers. Anonymous's DDoS attacks have targeted well over a dozen sites over the past few weeks.
According to TorrentFreak, the attacks against Gene Simmons were controversial among those associated with Anonymous, some arguing that it's better to target the legal mechanisms of the film and music industry, rather than artist themselves. But Simmons has painted a fairly large target on himself (or on his site, at least), by speaking out in recent weeks against file-sharing, arguing that the music industry should be suing more people: "Make sure your brand is protected, be litigious, sue anybody - take their homes, their cars, Don't let anybody cross that line."
Simmons's site is down at the time of publishing (Update: as of Monday morning, the website now redirects to the BitTorrent site Pirate Bay), but Slyck posted a copy of the response to the DDoS attack that was posted there yesterday:
Some of you may have heard a few popcorn farts re: our sites being threatened by hackers.
Our legal team and the FBI have been on the case and we have found a few, shall we say "adventurous" young people, who feel they are above the law.
And, as stated in my MIPCOM speech, we will sue their pants off.
First, they will be punished.
Second, they might find their little butts in jail, right next to someone who's been there for years and is looking for a new girl friend.
We will soon be printing their names and pictures.
We will find you.
You cannot hide.
Stay tuned
As Slyck notes, the ability to identify those who are participating in a distributed denial-of-service attack would be pretty challenging, if not impossible. But Simmons's threats and attitude (not to mention his lack of understanding of "hackers") echoes his misunderstanding that everyone who participates in peer-to-peer file-sharing is a criminal who needs to have their pants sued off or end up in jail.
Better round up the KISS Army, Gene. This battle could be brutal.
