Google’s the latest to take on IoT management headaches

Google wants to take on what may become one of the biggest cloud-computing needs of the next few years with a service that will manage IoT devices and help developers bring the data they generate into applications that use Google's analytics platforms.Its Google Cloud IoT Core, announced in a blog post on Tuesday, may be a good use of Google's reach, number-crunching power and device OS expertise. But the problem it aims to solve is daunting, and competitors are already focused on it.The good news for enterprises is that there are several solutions to IoT sprawl already available or taking shape. Just last week, VMware introduced Pulse IoT Center, the latest broad-based platform for setting up, managing and scaling IoT infrastructure. Cloud rival Microsoft has Azure IoT Hub, with a similar mission. Cisco Systems, General Electric and Nokia are also in the game.To read this article in full or to leave a comment, please click here

Microsoft, Amazon go after enterprises with new SAP cloud offerings

There are some fresh public cloud offerings on the horizon for SAP database customers, thanks to Microsoft Azure and Amazon Web Services. Both companies have announced new infrastructure services for the HANA database software aimed at giving customers tons of memory for workloads that need it.Azure customers will get access to M-series virtual machines that offer up to 3.5TB of RAM, designed for use with SAP’s database software. In addition, Microsoft announced Tuesday that it's working on new SAP HANA on Azure Large Instances to offer users between 4TB and 20TB of memory on a single machine specifically for use with software like the SAP Business Suite 4 HANA (S/4HANA).To read this article in full or to leave a comment, please click here

Worth Reading: A simple start to project management

Being able to track your work efficiently is a very useful skill. For years I completed my work but rarely tracked my work in a project management professional (PMP) sort of way. Sure, I’ve done the weekly reports, sticky notes, Outlook tasks, and Outlook calendar block scheduling, which are all useful. However, simple project management skills help create a consistent and straightforward approach to managing time, resources, and tasks. —Life of a Network Admin

Shadow Brokers teases more Windows exploits and cyberespionage data

A group of hackers that previously leaked alleged U.S. National Security Agency exploits claims to have even more attack tools in its possession and plans to release them in a new subscription-based service.The group also has intelligence gathered by the NSA on foreign banks and ballistic missile programs, it said.The Shadow Brokers was responsible for leaking EternalBlue, the Windows SMB exploit that was used by attackers in recent days to infect hundreds of thousands of computers around the world with the WannaCry ransomware program.To read this article in full or to leave a comment, please click here

Data center network monitoring best practices part 3: Modernizing tooling

Implementing your strategy using modern tooling

In the previous two posts we discussed gathering metrics for long term trend analysis and then combining it with event-based alerts for actionable results. In order to combine these two elements, we need strong network monitoring tooling that allows us to overlay these activities into an effective solution.

Understanding drawbacks of older network monitoring tooling

The legacy approach to monitoring is to deploy a monitoring server that periodically polls your network devices via Simple Network Management Protocol. SNMP is a very old protocol, originally developed in 1988. While some things do get better with age, computer protocols are rarely one of them. SNMP has been showing its age in many ways.

Inflexibility

SNMP uses data structures called MIBs to exchange information. These MIBs are often proprietary, and difficult to modify and extend to cover new and interesting metrics.

Polling vs event driven

Polling doesn’t offer enough granularity to catch all events. For instance, even if you check disk utilization once every five minutes, you may go over threshold and back in between intervals and never know.

An inefficient protocol

SNMP’s polling design is a “call and response” protocol, this means the monitoring server will Continue reading

WannaCry Makes Me Want to Cry!

As I read about the WannaCry ransomware attack, my brain is racing with thoughts about the causes and effects of this global incident.  Here’s my two cents:1.      Ransomware continues to be a growth business, and a bit of work can provide a serious return.  The FBI estimated that Ransomware payments topped $1 billion in 2016, and I wouldn’t be surprised if we saw 100% year-over-year growth. 2.      For those of us who’ve been in cybersecurity for a while, WannaCry brings back memories of the Internet worms we saw back in the 2000s (i.e. Code Red, Conficker, MSBlast, Nimda, etc.).  Once one person on a network was infected, WannaCry simply went out and infected other vulnerable systems on the network.  I knew that worm techniques would come back but I always thought they’d be used as a smokescreen for other attacks.  Looks like Ransomware and Internet worms can be as compatible as chocolate and peanut butter.To read this article in full or to leave a comment, please click here

Why WannaCry won’t change anything

The tally of damage from the WannaCry ransomware attack keeps growing, but it’s still not even close to bad enough to force real changes in cybersecurity. According to The New York Times, more than 200,000 machines in more than 150 countries around the world have been infected, but the responses being discussed still center around patches and passwords, updates and antivirus, backups and contingency plans. To read this article in full or to leave a comment, please click here
