Dangerous bugs leave open doors to SAP HANA systems

The most serious software flaws ever have been found in SAP's HANA platform, the in-memory database platform that underpins many of the German company's products used by large companies.Eight of the flaws are ranked critical, the highest severity rating, since attackers could use them to delete data, steal customer information and financial statements or change product pricing data."We found lot of stuff under the carpet," said Mariano Nunez, CEO of Onapsis, a Boston-based security company that focuses on protecting SAP systems.What is remarkable is that several of the 21 vulnerabilities found by Onapsis were remotely exploitable, meaning an attacker could gain access to HANA from afar over the Internet. To read this article in full or to leave a comment, please click here

EMC, hospital to pay $90,000 over stolen laptop with medical data

EMC and Hartford Hospital have agreed to pay US$90,000 to Connecticut in connection with the loss in 2012 of an unencrypted laptop containing patient information of 8,883 residents of the state, according to the state's attorney general.The laptop was stolen from the home of an employee of EMC and was never later recovered, according to an "Assurance of Voluntary Compliance" signed by EMC and the hospital with Attorney General George Jepsen.EMC had been hired as a contractor to the hospital to assist it on a quality improvement project relating to analyzing patient data. The employee had been employed by a company that was acquired by EMC and received the laptop that was stolen from that company.To read this article in full or to leave a comment, please click here

Cisco to MikroTik – command translation – BGP

 

In the world of network engineering, learning a new syntax can challenging especially if you need a lot of detail quickly. The command structure for RouterOS can be a bit challenging sometimes if you are used to Cisco CLI commands.  Most of us that have been in networking for a while got our start with Cisco gear and so it is helpful to draw comparisons between the commands, especially if you are trying to build a network with a MikroTik and Cisco router.

This is the first post in a series I’ve wanted to do for a while that creates a Rosetta stone essentially between IOS and RouterOS. We plan to tackle a number of other command comparisons like OSPF, MPLS and VLANs to make it easier for network engineers trained in Cisco IOS to successfully implement MikroTik / RouterOS devices. While many commands have almost the exact same information, others are as close as possible. Since there isn’t always an exact match, sometimes you may have to run two or three commands to get the information needed.

Kubernetes: Basic Concepts

I have been diving into Kubernetes lately, for both personal and $dayjob reasons. With the combined effect of my attendance at a recent Kubernetes workshop by Kelsey Hightower (on his very last day at CoreOS no less!) and also having the amazing opportunity to attend the inaugural and sold-out Kubecon that starts today, I figured it’s high time I tackle a “basics of Kubernetes” post.

This blog post is meant to serve as a very high-level introduction to Kubernetes concepts and components. If you are looking to stand up your own cluster, I encourage you to read the exceptional Kubernetes documentation. No, really. They’re exceptionally good docs.

Scheduling 101

Within the context of computer operating systems, the “scheduler” is the component that manages the assignment of compute resources to running processes. Especially in the early days before parallel computing and multicore systems, it was crucial to very carefully manage how much CPU time was allowed for the various running processes, so that the user could have a seamless experience. Even today with multicore systems, this is important to ensure that each core is utilized as evenly as possible, or at least to meet certain SLA requirements.

Teen hackers strike again, allegedly gain access to US arrest records database

A group of teenage hackers going by the name of “Crackas With Attitude” (CWA) are on a rampage, breaking into federal systems to embarrass the U.S. government.After gaining access to the personal AOL email account of CIA Director John Brennan last month, the teenagers reportedly broke into the Comcast email account of FBI Deputy Director Mark Giuliana’s wife, dumped personal details of thousands of government employees and then claimed to have gained access to the national Joint Automated Booking System, JABS, a database of arrest records, the FBI’s Internet Crime Complaint Center and the FBI’s Virtual Command Center.To read this article in full or to leave a comment, please click here

Ring’s Ring: Automating the Doorbell

Of all of the things that you might think of upgrading as you move into home or premises automation your doorbell may not immediately spring to mind. When it comes to entryway monitoring and security, the solution is usually to use a camera and sometimes a wireless doorbell. A company called, appropriately, Ring, has come out with a solution called, also appropriately, Ring. The Ring is a wireless device with a built in wide angle 720p HD camera, microphone, speaker, and pushbutton. The device communicates over your WI-Fi network (2.4 gHz 802.11 b/g/n with WPA2, WPA or 64-bit WEP) to Ring’s cloud services which allows you, on your iOS, Android, or Windows 10 device, to see and talk to whoever is outside your door from wherever you are as well as make a video record of activity.  To read this article in full or to leave a comment, please click here

Worth Reading: Better than Reno

Critically, today’s Internet assumes that most of the network’s resources are devoted to passing TCP traffic, and it also assumes that the flow control algorithms used by these TCP sessions all behave in approximately similar ways. If the switching and transmission resources of the network are seen as a common resource, then the assumption about the uniform behaviour of TCP sessions implies that these end-to-end transport sessions will behave similarly under contention. via circle id

Google Play Services 8.3 simplifies Android sign-in to a single tap

Google has updated Google Play Services. Users will notice changes from these updates in their apps quickly. For most Android users, Play Services remains out of sight and under the hood, serving apps with application programming interfaces (API), OAuth 2.0 identity services, security, malware scanning, and other mobile services.With the release of Google Play 8.3, Google has changed the sign-in button to make it work more like Chrome's web sign-in. When a new app that uses this updated Play Services release is downloaded, the developer can present the new branded sign-in button: Google This is a big interaction fix for users who previously had to select from multiple accounts, create new profiles, and grant user permissions just to sign into an app. It wouldn't be noticeable except for all the streamlined web sign-ins available, such as Google, Facebook, and Twitter, that reduce sign-in to a click. Now Android sign in to apps is reduced to a tap.To read this article in full or to leave a comment, please click here
