/. Recently published a post covering a draft NIST Standard that is in review [1]. This handler thought it would cause a disturbance in the force, but so far no one is discussing it. One of the big stand out changes is no more periodic password changes [2]. There are several others as well, and CSO Online has a fantastic summary review [3].

There are some clear differences that stand out right away in the introduction. As with most things, standards evolve as we learn.

padding:5px 10px"> Electronic authentication (e-authentication) is the process of establishing confidence in user identities electronically presented to an information system. E-authentication presents a technical challenge when this process involves the remote authentication of individual people over a network. This recommendation provides technical guidelines to agencies to allow an individual person to remotely authenticate his/her identity to a Federal Information Technology (IT) system. [4]

Digital identity is the unique representation of a subject engaged in an online transaction. A digital identity is always unique in the context of a digital service, but does not necessarily need to uniquely identify the subject. In other words, accessing a digital service may not mean that the physical representation of the underlying subject is known. [2]

The new draft goes on from there to outline digital identity and attempts to clearly define access and uses more risk based language.

One clear change that will shock users is the removal of periodic password changes. The handlers agree that a strong review of this draft is in order for security professionals as we can hear the users now:

Wait, you have been forcing me to change my passwords ALL THIS time, and now your saying it is not needed?

Another section that should be reviewed and discussed deeply is 5.2.7 Verifier Compromise Resistance. According to the section there should be some mechanism to verify compromise resistance. One could interpret this to run passwords against breached credential databases, however this is not specifically called out [2] [3].

In conclusion, this standard is a strong deviation from previous recommendations and should be reviewed for impact to your security practice. (There is that disturbance in the force we were looking for).

After learning that one of its most prized hacking tools was stolen by a mysterious group calling itself the Shadow Brokers, National Security Agency officials warned Microsoft of the critical Windows vulnerability the tool exploited, according to a report published Tuesday by The Washington Post. The private disclosure led to a patch that was issued in March.

Those same NSA officials, according to Tuesday's report, failed to communicate the severity of the vulnerability to the outside world. A month after Microsoft released the patch, the Shadow Brokers published the attack code, code-named EternalBlue, that exploited the critical Windows vulnerability. A month after that, attackers used a modified version of EternalBlue to infect computers around the world with malware that blocked access to data. Within hours of the outbreak of the ransomware worm dubbed WCry, infected hospitals turned away patients; banks, telecommunications companies, and government agencies shut down computers.

"NSA identified a risk and communicated it to Microsoft, who put out an immediate patch," Mike McNerney, a former Pentagon cybersecurity official and a fellow at the Truman National Security Project, told The Washington Post. The problem, he said, is that no senior official took the step of shouting to the world: "This one is very serious, and we need to protect ourselves."
