Maryam, it’s automated.

Re: Turning Big Blue into more green
Philbrit Very true but if they start the turn early enough they can succeed, its companies that don't recognize the need to turn that are facing the greatest issues. Apple was a prime example of turnaround they were all but dead until the iPod, iPhone and revamped laptops. It can be done.

Re: Turning Big Blue into more green
Susan thanks for the clarification that is a very interesting way of foiling an intrusion attack, is it fully automated or is it a manual effort?

Re: Turning Big Blue into more green
Maryam, This is the abstract from an IBM Research paper: Passwords are inherently vulnerable to dictionary attacks, but are quite secure if guessing attempts can be slowed down, for example by an online server. If this server gets compromised, however, the attacker can again perform an offline attack. The obvious remedy is to distribute the password verification process over multiple servers, so that the password remains secure as long as no more than a threshold of the servers are compromised. By letting these servers additionally host shares of a strong secret that the user can recover upon entering the cor- rect password, the user can perform further cryptographic tasks using this strong secret as a key, e.g., encrypting data in the cloud. Threshold password-authenticated secret sharing (TPASS) protocols provide exactly this func- tionality, but the two only known schemes by Bagherzandi et al. (CCS 2011) and Camenisch et al. (CCS 2012) leak the password if a user mistakenly executes the protocol with malicious servers. Authenticating to the wrong servers is a common scenario when users are tricked in phishing attacks. We propose the first t-out-of-n TPASS protocol for any n > t that does not suffer from this shortcoming. We prove our protocol secure in the UC frame- work, which for the particular case of password-based protocols offers important advantages over property-based definitions, e.g., by correctly modeling typos in password attempts.

Re: Turning Big Blue into more green
Though IBM has the resources, as you point out, the downturn has been anything but short-term. It takes a long time to turn around a big ship.

Re: Turning Big Blue into more green
While it's always hard to predict the future, IBM has the resources I would guess to recover from any temporary downturns while searching for ways to improve the bottom line among it's numerous business opportunities including moving along with the cloud transitions.

Re: Turning Big Blue into more green
Indeed, Maryam. Also, IBM had jumped into the Blockchain wagon, and is using a very interesting password security protocol.

Re: Turning Big Blue into more green
Susan agreed their moving in the right direction so if the focus continues they could very well claim a share of the market.

Re: Turning Big Blue into more green
It seems like it’s a time for transition for IBM as it moves into new technologies such as Blockchain. This is going to be interesting to watch, both the evolution into new technologies and what I believe it will be a financial recovery.

More Blogs from Scott Ferguson

For the last several years, CIOs and IT professionals have been wrestling with two specific issues as they work toward a cloud-centric future: Agile IT and the rush toward digital transformation. While enterprises want to keep innovating, finding a starting point and knowing which projects to tackle first remain a major obstacle.

To get a better handle on Agile IT and digital transformation, Light Reading Managing Editor Scott Ferguson recently spoke to two experts in these fields: Dan Kearnan, senior director of marketing for cloud at SAP, and Roy Illsley, a distinguished analyst with Ovum.

From its roots in industrial farm machinery and other equipment, John Deere has always looked for a technological edge. About 20 years ago, it was GPS and then 4G LTE. Now it's turning its attention to AI, machine learning and IoT.
Artificial intelligence and automation will become more integral to the enterprise, and 90% of all apps will have integrated AI capabilities by 2020, according to Oracle CEO Mark Hurd.
IBM is now offering access to Nvidia's Tesla V100 GPUs through its cloud offerings to help accelerate AI, HPC and other high-throughput workloads.
CIO Rhonda Gass is spearheading an effort to bring more automation and IoT to the factories making Stanley Black & Decker tools and other equipment.
