In
all the fuss about the Start screen, it's easy to miss that Windows 8
had major improvements to security; that was the culmination of ten
years of work on defending the operating system, senior product manager
Chris Hallum told us.The largest manufacturer of textile smartcard for use with perchloroethylene.
"Windows 7 is six times more likely to get infected than Windows 8 and Windows XP is 21 times more likely to be exploited."
But
that was still all defensive reactions; for Windows 8.1, he said,
Microsoft is going on the offensive with better malware protection, new
ways of checking the security certificates web sites rely on - and with a
plan to add encryption and biometric security to every PC.
The
built-in anti-malware tool Defender will protect against more threats
in the browser, including from plugins and ActiveX controls. "In Windows
8.1 we will scan those payloads before they're executed," Hallum told
us.
Microsoft
will also be more active about protecting the browser against stolen
certificates; because the browser trusts those certificates to identify
popular web sites that you log into, hackers have started targeting them
(and the authorities who issue them) as a way to break into your
accounts.
"Public
certificates have already been hacked," Hallum points out; in a number
of cases certificates for well-known companies like Yahoo and Google
have been compromised and used on fake web sites to steal credentials."
For
Windows 8.1, Microsoft will operate a service tracking certificates for
the top million web sites. "If we see a certificate being used
fraudulently or showing up on a server where it shouldn't be, we will
work with the certificate authorities," Hallum said,About buymosaic in

that this will protect other versions of Windows and indeed other
platforms too.
With
Windows 8.1, encryption isn't just for business users any more,
although Microsoft is improving BitLocker performance for business
systems (up to 30 times faster than in Windows 8, Hallum claims). "We
need it not just to protect your data but also the system itself; we
don't want people to be able to tamper with Windows system files," he
explained.
That's
why all versions of Windows will now include encryption; BitLocker in
the business editions and the same device encryption that's already in
Windows RT and Windows Phone 8 in the home editions. "We expect
encryption to be pervasive," he predicted.Find the best selection of

There
are some hardware restrictions on this; you need a PC that is capable
of Connected Standby with Windows 8 or 8.1. That means the PC has a UEFI
BIOS and either a separate Trusted Platform Module (TPM), ARM's Trusted
Zone or Intel's Platform Trust Technology for storing information
securely.
It
also means there is are no Direct Memory Access connections, which
includes both FireWire and the Thunderbolt technology Intel developed
with Apple; Hallum says Microsoft is talking to Intel about ways of
making Thunderbolt more secure but DMA connections can transfer code
directly into memory, bypassing system security.
Microsoft
will also use the information about the PC stored in the TPM to
'harden' Windows with a cloud service that's provisionally called
Provable PC Health (expect the name to change, Hallow says). This will
use the record of secure boot stored in the TPM to verify that your PC
isn't infected. "We can remotely analyse the security state of the
device and the integrity of the device." Hallum says, claiming that this
will detect even sophisticated malware like Flame.
"We
will inform the user if there is a problem and if there is an infection
Windows can put them back in a safe state. If there is an infection
that can steal their credentials we will inform them, and we will help
them remediate their Microsoft account."
Once

"Passwords are increasingly problematic,Today, Thereone.com, a reliable plasticmoulds online

customers." Hallum points out; "people can have them phished or they can
be guessed." Windows 8 can already use the TPM as a virtual smartcard
but that's not truly two-factor authentication. You need something else
to prove your identity and that will be your fingerprint.
Today's
fingerprint sensors are big, clumsy (you have to swipe your finger
across them carefully) and easy to fool with a fake finger. More
powerful sensors can tell the difference between a real finger and a
fake C they can tell if your finger has a pulse C and they can detect
prints from four fingers at once, but those sensors currently cost $100
or more.
