Microsoft Security Intelligence Report Volume 14

Yesterday, Microsoft released volume 14 of its Security Intelligence Report (SIRv14) which included new threat intelligence from over a billion systems worldwide.  The report was focused on the 3rd and 4th quarters of 2012.
One of the most interesting threat trends to surface in the enterprise environment was the decline in network worms and rise of web-based attacks.  The report found:



·         The proportion of Conficker and Autorun threats reported by enterprise computers each decreased by 37% from 2011 to 2H12.
·         In the second half of 2012, 7 out of the top 10 threats affecting enterprises were associated with malicious or compromised websites.
·         Enterprises were more likely to encounter the iFrame redirection technique than any other malware family tracked in 4Q12.
·         One specific iFrame redirection family called IframeRef, increased fivefold in the fourth quarter of 2012 to become the number one malicious technique encountered by enterprises worldwide.   
·         IframeRef was detected nearly 3.3 million times in the fourth quarter of 2012.

The report also takes a close look at the dangers of not using up-to-date antivirus software in an article titled “Measuring the Benefits of Real-time Security Software.”  New research showed that, on average, computers without AV protection were five and a half times more likely to be infected

The study also found that 2.5 out of 10, or an estimated 270 million computers worldwide were not protected by up-to-date antivirus software

Whilst many of the findings surrounding real-time protection seem pretty obvious, the numbers are pretty startling.  As security is often best implemented using a strength-in-depth, or rings approach, anti-virus or real time malware detection seems to be taking a back seat.  For mobile devices, or devices based on Linux this can become a significant issue, especially if those devices carry email destined for Microsoft based machines.

The Role of Identity Management in the GDPR

Unless you have been living in a darkened room for a long time, you will know the countdown for the EU's General Data Protection Regulation is dramatically coming to a head.  May 2018 is when the regulation really takes hold, and organisations are fast in the act on putting plans, processes and personnel in place, in order to comply.

Whilst many organisations are looking at employing a Data Privacy Officer (DPO), reading through all the legalese and developing data analytics and tagging processes, many need to embrace and understand the requirements with how their consumer identity and access management platform can and should be used in this new regulatory setting.

My intention in this blog, isn't to list every single article and what they mean - there are plenty of other sites that can help with that.  I want to really highlight, some of the more identity related components of the GDPR and what needs to be done.

Top 5 Security Predictions for 2016

It's that time of year again, when the retrospective and predictive blogs come out of the closet, just before the Christmas festivities begin.  This time last year, the 2015 predictions were an interesting selection of both consumer and enterprise challenges, with a focus on:


Customer Identity ManagementThe start of IoT security awarenessReduced Passwords on MobileConsumer PrivacyCloud Single Sign On
In retrospect, a pretty accurate and ongoing list.  Consumer related identity (cIAM) is hot on most organisation's lips, and whilst the password hasn't died (and probably never will) there are more people using things like swipe login and finger print authentication than ever before.

But what will 2016 bring?


Mobile Payments to be Default for Consumers

2015 has seen the rise in things like Apple Pay and Samsung Pay hitting the consumer high street with venom.  Many retail outlets now provide the ability to "tap and pay" using a mobile device, with many banks also offer…

Customer Data: Convenience versus Security

Organisations in both the public and private sector are initiating programmes of work to convert previously physical or offline services, into more digital, on line and automated offerings.  This could include things like automated car tax purchase, through to insurance policy management and electricity meter reading submission and reporting.

Digitization versus Security

This move towards a more on line user experience, brings together several differing forces.  Firstly the driver for end user convenience and service improvement, against the requirements of data security and privacy.  Which should win?  There clearly needs to be a balance of security against service improvement.  Excessive and prohibitive security controls would result in a complex and often poor user experience, ultimately resulting in fewer users.  On the other hand, poorly defined security architectures, lead to data loss, with the impact for personal exposure and brand damage.
