Towards usable checksums: automating the integrity verification of web downloads for the masses

Towards usable checksums: automating the integrity verification of web downloads for the masses Cherubini et al., CCS’18

If you tackled Monday’s paper on BEAT you deserve something a little easier to digest today, and ‘Towards usable checksums’ fits the bill nicely! There’s some great data-driven product management going on here as the authors set out to quantify current attitudes and behaviours regarding downloading files from the Internet, design a solution to improve security and ease-of-use, and then test their solution to gather feedback and prepare for a more widely deployed beta version.

When I was growing up we were all taught “Don’t talk to strangers”, and “Never get in a stranger’s car”. As has been well noted by others, so much for that advice! Perhaps the modern equivalent is “Don’t download unknown files from the Internet!” This paper specifically looks at applications made directly available from developer websites (vs downloads made through app stores).

A popular and convenient way to download programs is to use official app stores such as Apple’s Mac App Store and Microsoft’s Windows Store. Such platforms, however, have several drawbacks for developers, including long review and validation times, technical restrictions (e.g., sandboxing), Continue reading

Python Pandas – Reading text files got a lot better.

Problem Statement – Have a list of VMWare Instances and wanted to quickly iterate and see what VMs are powered on, this has nothing to do with Vmware or ESXI, look at the below image, programmatically I want to pick two specific rows and perform dictionary operations on them.

Git – https://github.com/yukthr/auts/blob/master/random_programs/pandas_vmware_esxi.py

for someone like me who is partly into programming and mostly into networking, anything effective is easy, I could have gone with the other way of doing this but  since Pandas are effective i would text parsing with them.

 

I only want two sections which are of interest to me, in a normal way maybe I should have pasted this in excel and Do a text to the column and do a manual data extraction, but wanted to do it with Pandas and they are powerful.

First things first

  • Read with Pandas
  • Read the text
  • If possible convert into CSV (as I have some experience with csv file operations)
  • Then split the Columns and make the dictionary for further use

 

 

Let’s see how this proceeds

Pandas make it so powerful to just pick Columns out of the fly, in this case, I wanted Continue reading

Pratt & Whitney Launches HPC to The Cloud To Push Jet Engine Design

HPC and the cloud have an uneasy, lukewarm relationship. Some corporations running HPC environments take the view that they have the infrastructure and software capabilities they need to run their own often massive workloads and taking on the networking costs, security concerns and management hassles of running applications and keep data in the cloud doesn’t make sense to them. …

BiB 060: Focus On Your Data & Not Where It’s Stored With HammerSpace

The simplest way to describe HammerSpace is that they are an abstraction layer between data and metadata. David Flynn, CEO described it like this. “We have introduced an abstraction which separates the data consumer side and the storage infrastructure side. And that’s really what’s necessary before we can manage data in the cloud.”

Data centers are set to grow and become more complex, survey finds

Companies will invest more in data centers in the coming years, but it won’t necessarily be around compute. That's according to a new survey by AFCOM, the data center and IT management education company.This is AFCOM’s first study on the subject in two years, and it found that ownership, renovations, and building of new data centers were on the increase. It found 58 percent of survey respondents currently own between two and nine data centers and that on average, 5.3 data centers will be renovated per organization. That number increases to 7.8 data centers over the course of 12 months.Once again, we see the notion of people shutting down their data centers and moving everything to the cloud is evaporating.To read this article in full, please click here

2018 Survey on Policy in Asia-Pacific: We Need to Do Something About IoT Security

Earlier this year, we asked Internet users across Asia-Pacific just how secure they thought their smart gadgets were. The findings, gathered from 950 respondents in 22 economies, yielded some interesting insights. Over half of those polled lack confidence that IoT devices are sufficiently secure. A similar percentage feel that they do not have enough information on the security of their device.

As connected devices move into our personal spaces – homes, offices and our bodies – amassing more and more data about us and our activities at a dizzying pace, our report, published last week, highlights how much work still needs to be done to build trust in the Internet of Things (IoT) ecosystem.

Asia-Pacific is undoubtedly a major area of growth for the IoT industry, with countries like China and India rapidly becoming some of the biggest markets for consumer IoT devices. We are also a formidable producer, with established brands like Xiaomi and Samsung churning out wearables, smart appliances, and virtual assistants, and numerous startups joining the fray.

Indeed, the report found that a substantial number of respondents already own IoT devices, with a further 73% planning to purchase an IoT device in the next 12 months. Continue reading
