Troubleshooting: Models

How well can you know each of these four systems? Can you actually know them in fine detail, down to the last packet transmitted and the last bit in each packet? Can you know the flow of every packet through the network, and every piece of information any particular application pushes into a packet, or the complete set of ever changing business requirements?

Obviously the answer to these questions is no. As these four components of the network combine, they create a system that suffers from combinatorial explosion. There are far too many combinations, and far too many possible states, for any one person to actually know all of them.

How can you reduce the amount of information to some amount a reasonable human can keep in their minds? The answer—as it is with most problems related to having too much information—is abstraction. In turn, what does abstraction really mean? It really means you build a model of the system, interacting with the system through the model, rather than trying to keep all the information about every subsystem, and how the subsystems interact, in your head. So for each subsystem of the entire system, you have a model you are Continue reading

What it takes to be a security architect

Security architects are the people responsible for maintaining the security of their organizations’ computer systems, and as such they must be able to think as hackers do in order to anticipate the tactics attackers can use to gain unauthorized access to those systems, according to the InfoSec Institute.Anyone in this position can expect to have to work odd hours on occasion, and needs to be constantly up to date on the latest security threats and available tools.Sometimes people who ultimately take on the role of security architect, like Jerod Brennen, could not have predicted such a career direction when they were younger. When Brennen began attending Capital University, a small liberal arts college in Ohio, in the 1990s, he intended to pursue a career in the film industry as a composer.To read this article in full or to leave a comment, please click here(Insider Story)

Mobile is the new desktop, and that’s good for enterprise apps

Android surpassed Microsoft's Windows in March to become the most popular operating system on the internet, according to figures compiled by GlobalStats, the research arm of web analytics company StatCounter.GlobalStats found that, worldwide, Android had a 37.93 percent internet usage market share, just ahead of Windows at 37.91 percent. "This is a milestone in technology history and the end of an era," said Aodhan Cullen, StatCounter's CEO. "It marks the end of Microsoft’s leadership worldwide of the OS market which it has held since the 1980s. It also represents a breakthrough for Android, which held just 2.4 percent of global internet usage share only five years ago."To read this article in full or to leave a comment, please click here

Why smart contracts can’t be fully automated

Blockchain technology has been generating excitement in the public and private sectors for the past several years for many reasons — a prominent one being support for self-executing contracts commonly referred to as smart contracts. But while smart contracts have the potential to streamline many business processes, full automation isn't likely anytime in the foreseeable future."Smart contracts are a combination of some certain binary actions that can be translated into code and some reference to plain language like we have today that is open to litigation if you mess up," says Antonis Papatsaras, CTO of enterprise content management company SpringCM, which specializes in contract workflow automation. "I think it's going to take forever."To read this article in full or to leave a comment, please click here

Vendors approve of NIST password draft

A recently released draft of the National Institute of Standards and Technology’s (NIST's) digital identity guidelines has met with approval by vendors. The draft guidelines revise password security recommendations and altering many of the standards and best practices security professionals use when forming policies for their companies.The new framework recommends, among other things: Remove periodic password change requirements There have been multiple studies that have shown requiring frequent password changes to actually be counterproductive to good password security, said Mike Wilson, founder of PasswordPing. NIST said this guideline was suggested because passwords should be changed when a user wants to change it or if there is indication of breach.To read this article in full or to leave a comment, please click here

Worth Reading: Who really has fast lanes?

Internet Association members sometimes say that they could actually afford to pay more for fast lanes but they are worried about the little guys, the startup, who may not be able to pay more and whose websites, therefore, won’t be as zippy as they need to be. They’re worried about innovation. They’re worried about you. In fact, however, the web giants like Google and Amazon have private networks which connect to the Internet in many locations. They have data caches (think of them as content warehouses) around the world. Their websites DO pop up faster than yours because their bits travel mostly on their private networks and avoid Internet backbone and interchange congestion. In other words, they have private fast lanes. You can’t achieve this speed for your website unless you A) build a private network of your own (unlikely); B) host your website on Amazon or Google in which case they MAY share some of their private access network. —CircleID

FCC should produce logs to prove ‘multiple DDoS attacks’ stopped net neutrality comments

After John Oliver urged viewers of HBO’s Last Week Tonight to fight for net neutrality (again) and post comments on the FCC's site, people were not able to submit comments because the site turned to molasses.The FCC blamed the problem on “multiple” DDoS attacks: “These were deliberate attempts by external actors to bombard the FCC’s comment system with a high amount of traffic to our commercial cloud host. These actors were not attempting to file comments themselves; rather they made it difficult for legitimate commenters to access and file with the FCC.”To read this article in full or to leave a comment, please click here

Docker Enterprise Edition Brings New Life Back to Legacy Apps at Northern Trust

Many organizations understand the value of building modern 12-factor applications with microservices. However, 90+% of applications running today are still traditional, monolithic apps. That is also the case for Northern Trust – a 128-year old financial services company headquartered in Chicago, Illinois. At DockerCon 2017, Rob Tanner, Division Manager for Enterprise Middleware at Northern Trust, shared how they are using Docker Enterprise Edition (EE) to modernize their traditional applications to make them faster, safer, and more performant.

Bringing Agility and Security to Traditional Apps

Founded in 1889, Northern Trust is a global leader in asset servicing, asset management, and banking for personal and institutional clients. Their clients expect best-of-breed services and experiences from Northern Trust and Rob’s team plays a large role in delivering that. While their development teams are focused on microservices apps for greenfield projects, Rob is responsible for over 400 existing WebLogic, Tomcat, and .NET applications. Docker EE became the obvious choice to modernize these traditional apps and manage their incredibly diverse environment with a single solution.

Containerizing traditional applications with Docker EE gives Northern Trust a better way to manage them and some immediate benefits:

IDG Contributor Network: Settling scores with risk scoring

Risk scores seem all the rage right now. Executives want to know what their risk is. The constant stream over the past few years of high profile breaches and the resulting class action lawsuits, negative PR, loss in share price, cybersecurity insurance pay-out refusals, and even termination of liable executives has made this an urgent priority. The problem is we haven’t really developed a good way to measure risk.Most risk score approaches are restricted by a very simple limitation: They are not vendor agnostic or universal. The solution used to calculate risk is limited by the data it collects, which can vary widely. What is the risk score composed of? More important, what doesn’t it capture? One vendor will include only network and system vulnerabilities, another bundles application vulnerabilities into the mix, and yet another adds user behaviour. Agreeing on the “right” mix still eludes us with no real authoritative standards that define what should be included. Every scoring methodology is subjective, which is surely a sign of how inherently unscientific the entire approach is.To read this article in full or to leave a comment, please click here
