Passwords And Why They're Going Nowhere

Passwords have been the bane of security implementers ever since they were introduced, yet still they are present on nearly every app, website and system in use today.  Very few web based subscription sites use anything resembling two-factor authentication, such as one-time-passwords or secure tokens.  Internal systems run by larger organisations implement additional security for things like VPN access and remote working, which generally means a secure token.

Optimized Role Based Access Control

RBAC.  It's been around a while.  Pretty much since access control systems were embedded in to distributed operating systems.  It often appears in many different forms, especially at an individual system level, in the form of groups, or role based services, access rules and so on.  Ultimately, the main focus is the grouping of people and their permissions, in order to accelerate and simplify user account management.

Insurance For Information Security

We can get insurance for virtually anything these days.  Cars obviously (albeit if that wasn't law, how many would pay for it?).  Ourselves.  Pets.  Eyes.  Teeth.  Holidays.  You name it and The Meerkat can sort it out.  The market for insurance is highly complex, with econometrics playing a large part in determining the potential risk levels of individual insurance consumers.  The insurance underwriters, like any other capitalist organisation, are primarily concerned with making a profit.  They won't provide insurance to those they deem a probable risk and charge higher premiums to those that are a possible risk.  Insurance for the consumer is to cover loss against an unexpected even.  The risks of that unexpected even occurring will obviously change.  Flying to Spain on holiday increases the risk of having a plane crash.  Getting old increases the risk of falling and breaking your hip.  But a lot of the time, the unexpected risk is just that: unexpected.

Identity In The Modern Enterprise

I was on a webinar last week by the highly articulate Eve Maler from Forrester, where the discussion was around the future of identity and access management.  Everyone has an opinion on the future of everything, and IAM is certainly no different.  The view of IAM 1.0 (enterprise provisioning) and IAM 2.0 (federated identity, 'cloud' services and so) is continually evolving and it's pretty clear that identity management now has a greater role to play for many organisations, as they look to embrace things like increased mobility and out sourced service driven applications.

Information Security: Time for a Different Approach

This last few weeks have seen, yet again, some pretty significant hacks (namely the Evernote hack).  Large amounts of user data, including passwords, were released into the wild.  The situation could have been worse in the Evernote case, but at least the passwords were salted and hashed.  Evernote's response, has been to perform a mass password reset on it's user base, in a proactive damage limitation style exercise and no doubt several internal streams of investigation will be looking for the who, what and why behind the attack.

Security is Reactive
I've blogged on the topic of reactionary security on a few occasions recently ("Protection Without Detection", "Preventative -v- Detective Security") and it seems the approach is still pretty much the default  (Or perhaps security is only really questioned and tested after an event?).  There are of course, lots of 'pro-active' components to security.  Hashing a password could be seen as one for examp…
