The Ten Immutable Laws Of Security: Version 2

You can’t patch these, but you can take steps to be more aware of these law’s.

 

Law #1: If a bad guy can persuade you to run his program on your computer, it’s not solely your computer anymore.

Law #2: If a bad guy can alter the operating system on your computer, it’s not your computer anymore.

Law #3: If a bad guy has unrestricted physical access to your computer, it’s not your computer anymore.

Law #4: If you allow a bad guy to run active content in your website, it’s not your website any more.

Law #5: Weak passwords trump strong security.

Law #6: A computer is only as secure as the administrator is trustworthy.

Law #7: Encrypted data is only as secure as its decryption key.

Law #8: An out-of-date anti-malware scanner is only marginally better than no scanner at all.

Law #9: Absolute anonymity isn’t practically achievable, online or offline.

Law #10: Technology is not a panacea.

Tech Short Q&A: What is a Hypervisor?

It’s interesting that this classification isn’t new. In fact it was classified by Gerald J. Popek back in 1974 in the article “Formal Requirements for Virtualizable Third Generation Architectures”

So to answer the question:

A hypervisor is a hardware virtualization technique which allows multiple guest operating systems to run on a single host system hardware at the same time. Each guess operating system share the hardware its host. Hardware such as processor, memory as if it is its own.

Type 1 Hypervisors are known as bare-metal. These run directly on the host hardware and have full control of the hardware resources while managing guest operating systems.

Type 2 Hypervisors are hosted and run within a host operating systems environment to provide virtualization resources

Examples of Type 1 Hypervisors include: VMware ESXi, Citrix XenServer, Microsoft Hyper-V, KVM (Kernel-based Virtual Machine) on Linux.

Examples of Type 2 Hypervisors include: VMware Workstation / Player / Fusion, Sun VirtualBox, Parallels

What is Sway

What is Sway?

That was the question I had asked this morning when I logged into my Office 365 account.

Sway is a free app from Microsoft Office. It lets you create and share interactive reports, presentations, personal stories, newsletters, vacation memories, school and work projects, and more. In this video, you’ll see an example of getting started creating your first Sway!

 

 

 

Cool, lets give it a try
