Most acute storage pain points, letdowns

Things don’t always go as planned with new technologies. Two new research reports document the struggles, disappointments and false starts that challenge enterprise storage pros as they modernize their infrastructures for digital business.451 Research asked enterprise IT pros to rank their most pressing storage pains. “Data/capacity growth” landed in the top spot, according to the firm’s research brief. “Meeting disaster recovery requirements” and “high cost of storage” ranked second and third, respectively, among survey respondents.“The core challenges in storage are shifting; public cloud is beginning to assume the burden of inexorable data growth, and the emphasis is moving to other areas, such as effectively managing data and storage across both on- and off-premises locations,” according to Simon Robinson, research vice president at 451 Research and author of the report, Top three storage pain points for enterprise customers.To read this article in full or to leave a comment, please click here

Shrubbery.net TACACS+ daemon and Junos

Axians Professional Services normally recommends using RADIUS authentication to our customers, but one of our customers uses TACACS.  We did some type-approval testing of new Junos release for them recently and had to set up a TACACS+ daemon in the lab to make sure authentication still worked following the upgrade.

Shrubbery.net very helpfully provide a TACACS+ implementation that you can download to a Linux host for this purpose, but the documentation is a bit light on their website, and what you find using Google is naturally somewhat Cisco-specific.  So here are some notes on getting a basic setup going with Shrubbery’s tac_plus daemon and Junos.  Maybe this will help someone else.

 

Create the Junos Config

First, you need to set up the Junos side of things.  You need to do three things:

  1. Create a tacplus-server in the config
  2. Add tacplus to the authentication-order
  3. Create a ‘local user’ account that has no password, but gives anyone belonging to it the appropriate privileges.

 

Create the TACACS server

On the ‘web: All you ever wanted to know about EIGRP

In episode 5 the Network Collective panel dives deep into the inner-workings of EIGRP and how to tune the protocol to work best for you. This isn’t your run of the mill EIGRP training session though, so buckle up and dig in to learn a lot about a protocol which appears pretty straight forward on the surface.

This last week I was on the Network Collective discussing EIGRP with Nick Russo; even if you think this protocol is dead, it’s well worth watching or listening to. And if this isn’t enough EIGRP for you, the EIGRP book on Addision-Wesley is another good resource.

The attacks, which include a malware-as-a-service (MaaS) known as MacSpy and a ransomware-as-a-service called MacRansom — both of which attackers can purchase to use to direct at a target— …

Crash Override: Malware that took down a power grid may have been a test run

Two security firms have released reports about the malware which was used in the December 2016 Ukraine power outage, warning that the partial power outage in Kiev may have been test run; the malware could be leveraged against other countries, including the US.The malware, dubbed Crash Override in the Dragos report (pdf) and Industroyer in the ESET report (pdf), has nothing to do with espionage and everything to do with cyber-sabotage.Crash Override, Dragos says, “is the first ever malware framework designed and deployed to attack electric grids.” It could be “leveraged at multiple sites simultaneously.” Dragos founder Robert M. Lee told Reuters, “The malware is capable of causing outages of up to a few days in portions of a nation's grid, but is not potent enough to bring down a country's entire grid.”To read this article in full or to leave a comment, please click here
