Why have just one operating system

Filed under
OS
Software

I'm currently running three different operating systems on my desktop PC. There's my habitual Kubuntu Linux, a version of Android (more common on phones), and Windows. They're running simultaneously and I can select any one with a mouse click.

This magic comes about by the use of "virtualisation" - which simply refers to the creation of a virtual (rather than an actual) version of something. With the right software and a reasonably powerful PC, you can build virtual "compartments" inside your computer that look and act like a whole separate machine. That allows you, for example, to run Linux and Mac on Windows, try out a new web server or run an old operating system such as DOS or OS/2, all without disturbing your current system - or having to reboot. "Guest" systems can communicate with the underlying (or "host" operating system) via shared folders, networking or the clipboard, and you can install and run as many VMs (virtual machines) as you like, with disk space and memory the only real limitation.

Security Leftovers

  • Chrome vulnerability lets attackers steal movies from streaming services
    A significant security vulnerability in Google technology that is supposed to protect videos streamed via Google Chrome has been discovered by researchers from the Ben-Gurion University of the Negev Cyber Security Research Center (CSRC) in collaboration with a security researcher from Telekom Innovation Laboratories in Berlin, Germany.
  • Large botnet of CCTV devices knock the snot out of jewelry website
    Researchers have encountered a denial-of-service botnet that's made up of more than 25,000 Internet-connected closed circuit TV devices. The researchers with Security firm Sucuri came across the malicious network while defending a small brick-and-mortar jewelry shop against a distributed denial-of-service attack. The unnamed site was choking on an assault that delivered almost 35,000 HTTP requests per second, making it unreachable to legitimate users. When Sucuri used a network addressing and routing system known as Anycast to neutralize the attack, the assailants increased the number of HTTP requests to 50,000 per second.
  • Study finds Password Misuse in Hospitals a Steaming Hot Mess
    Hospitals are pretty hygienic places – except when it comes to passwords, it seems. That’s the conclusion of a recent study by researchers at Dartmouth College, the University of Pennsylvania and USC, which found that efforts to circumvent password protections are “endemic” in healthcare environments and mostly go unnoticed by hospital IT staff. The report describes what can only be described as wholesale abandonment of security best practices at hospitals and other clinical environments – with the bad behavior being driven by necessity rather than malice.
  • Why are hackers increasingly targeting the healthcare industry?
    Cyber-attacks in the healthcare environment are on the rise, with recent research suggesting that critical healthcare systems could be vulnerable to attack. In general, the healthcare industry is proving lucrative for cybercriminals because medical data can be used in multiple ways, for example fraud or identify theft. This personal data often contains information regarding a patient’s medical history, which could be used in targeted spear-phishing attacks.
