Why You Should Cancel Your Social Media Accounts

Over the past ten years, the world generally has noticed serious social media websites like MySpace, Twitter, and Facebook which have all generated different ways for people to interact and connect with other people. Facebook is known as the biggest social website. Today we have more than a billion users that make use of Facebook. In the future, with kids growing up and joining the social media platform, the number of people will increase. Facebook has been used for both personal and business communication, and its usage has brought lots of advantages in terms of sharing ideas, increasing connectivity, and learning online.

But as time passes, some studies have merged networking online with different disorders that come from the minds of the users. These disorders include low self-esteem, anxiety, depression, and a lot of others. Because social media is a product of the 21^st century, lots of questions relating to their impact on the health of its users mentally haven’t gotten desired answers yet. Because these online services are linked to the general population, any confirmed connection in the future between these diseases and these social media platforms could turn to a serious problem.

Hybrid cloud keeps human capital management firm nimble

Ceridian is betting on hybrid cloud, network virtualization and automation as it aims to improve IT service delivery, weed out inefficiencies and bolster security.The human capital management (HCM) company recently completed its transition to a cloud architecture, shuttering its on-premises data centers and migrating its applications and back-office systems to multiple clouds. "We are a true consumer of hybrid cloud technology," says CIO Warren Perlman. "We have operations in both [VMware Cloud on AWS] as well as native AWS, and also native Azure."To read this article in full, please click here

Used IT equipment: Millennials push enterprises into the circular economy

The Millennial generation is becoming a driving force behind the circular economy of used IT equipment.IT shops have typically bought used gear if they needed to replace old equipment and couldn't get parts from the vendor. But the idea of buying a low-mileage server with one or two years of use wasn't very popular. Companies typically bought new.But that's changing. IT shops of all sizes are increasingly buying used gear, both brand name and white box brands from China, according to IDC. The research firm puts the CAGR at 5% and estimates sales of used IT infrastructure gear will reach $36 billion by 2024. The deals are being done through the major OEMs as well as resellers like ITRenew, which buys servers from hyperscalers, refreshes them, certifies they are functioning, and resells them.To read this article in full, please click here

Achieve Multi-Cloud Application Scalability for Modern Apps

The Case for Self-Healing Networks

Digital transformation has changed the way applications are deployed and consumed. The end-user to application journey has become increasingly complex and is a key objective for the Modern Network.  End-users are more distributed, and applications run on heterogenous infrastructure often delivered from on-prem data centers, IaaS, SaaS, and public cloud locations.  On average, enterprises use hundreds of applications.  The number of end-user and IoT devices have also increased exponentially. They include infusion pumps in hospitals to Point of Sale systems in retail.  These devices access applications from manufacturing floor, carpeted offices, homes or while users are on the move. As more devices and applications are enabled, the network increases in both complexity and value to the enterprise.

What has become increasingly clear is the need for advanced self-healing solutions that compensate for this complexity by helping IT teams shift to a proactive mode of operating a network.  Several tools exist that provide domain or service-specific insights, but it is left to the IT teams to make sense of the volumes of data generated by these fragmented solutions to detect issues and perform root cause analysis.  The dynamic nature of the network, device density, and the volume of data and Continue reading

Fault Tolerant Network Design for Application High Availability

Enterprises are growing increasingly dependent on modern distributed applications to innovate and respond quickly to new market challenges.  As applications grow in significance, the end-user experience of the application has become a key differentiator for most businesses.  Understanding what kind of application performance the end-users experience, optimizing the infrastructure, and quickly identifying the source of any issues has become extremely critical.

The Modern Network framework puts the end-user experience at the forefront.  It helps our customers provide the public cloud experience on-premise with an on-demand network that enforces secure connectivity and service objectives across on-premise and cloud environments.  As applications become more distributed, the increased application resiliency and efficiency often comes at the cost of increased contention for shared resources.  The dynamic nature of the network, device density, and the volume of data and transactions generated makes this even more challenging. Managing network complexity and simplifying network operations in such environments requires a well architected network with support for modern cloud concepts such as availability zones that provide fault tolerance.  Similarly, effective network-level fault isolation requires the ability to create self-contained fault domains that facilitate network resiliency, disaster recovery and avoidance, and end-to-end root cause(s) analysis throughout the Continue reading

Zero-Touch Provisioning for Juniper

Juniper’s official documentation on ZTP explains how to configure the ISC DHCP Server to automatically upgrade and configure on first boot a Juniper device. However, the proposed configuration could be a bit more elegant. This note explains how.

When booting for the first time, a Juniper device requests its IP address through a DHCP discover message, then request additional parameters for autoconfiguration through a DHCP request message:

Dynamic Host Configuration Protocol (Request)
    Message type: Boot Request (1)
    Hardware type: Ethernet (0x01)
    Hardware address length: 6
    Hops: 0
    Transaction ID: 0x44e3a7c9
    Seconds elapsed: 0
    Bootp flags: 0x8000, Broadcast flag (Broadcast)
    Client IP address: 0.0.0.0
    Your (client) IP address: 0.0.0.0
    Next server IP address: 0.0.0.0
    Relay agent IP address: 0.0.0.0
    Client MAC address: 02:00:00:00:00:01 (02:00:00:00:00:01)
    Client hardware address padding: 00000000000000000000
    Server host name not given
    Boot file name not given

Self-promotion Disguised as Research Paper

From AI is wrestling with a replication crisis (HT: Drew Conry-Murray)

Last month Nature published a damning response written by 31 scientists to a study from Google Health that had appeared in the journal earlier this year. Google was describing successful trials of an AI that looked for signs of breast cancer in medical images. But according to its critics, the Google team provided so little information about its code and how it was tested that the study amounted to nothing more than a promotion of proprietary tech (emphasis mine).

No surprise there, we’ve seen it before (not to mention the “look how awesome we are, but we can’t tell you the details” Jupiter Rising article).

SAD DNS Explained

This week, at the ACM CCS 2020 conference, researchers from UC Riverside and Tsinghua University announced a new attack against the Domain Name System (DNS) called SAD DNS (Side channel AttackeD DNS). This attack leverages recent features of the networking stack in modern operating systems (like Linux) to allow attackers to revive a classic attack category: DNS cache poisoning. As part of a coordinated disclosure effort earlier this year, the researchers contacted Cloudflare and other major DNS providers and we are happy to announce that 1.1.1.1 Public Resolver is no longer vulnerable to this attack.

In this post, we’ll explain what the vulnerability was, how it relates to previous attacks of this sort, what mitigation measures we have taken to protect our users, and future directions the industry should consider to prevent this class of attacks from being a problem in the future.

DNS Basics

The Domain Name System (DNS) is what allows users of the Internet to get around without memorizing long sequences of numbers. What’s often called the “phonebook of the Internet” is more like a helpful system of translators that take natural language domain names (like blog.cloudflare.com or gov.uk) and Continue reading
