IT Simplified: Email Authentication

Email authentication helps validate who is sending emails. Email authentication methods can help protect your domain, your brand, your reputation, as well as help improve deliverability overall. Here we understand what and how’s of email authentication and what happens after you hit the button send.

Email authentication isn’t just about security – it’s also about deliverability. By putting records in place and authenticating your emails, you can protect your brand and help your emails successfully reach the inbox. It helps in preventing email fraud, improve your email deliverability, and ensure continued delivery.

IT Simplified: Distributed denial of service

Hack vector created by freepik – www.freepik.com

Distributed denial- of- service attacks, or  DDoS attacks are a variant of denial-of-service attacks in which an attacker or a group of attackers employs multiple machines to simultaneously carry out a Denial of service(DoS) attack, thereby increasing its effectiveness and strength. The “army” carrying out the attacks are mostly often composed of innocent infected zombie computers such as an home router manipulated to be bots and being part of a botnet. These bots are cleverly controlled by the attacker via a Command and Control Server . It also insures the anonymity of the original attack since the distributed denial of service attack traffic originates from the bots’ IPs rather than the attacker’s. They may still be short, but may persist as powerful and sudden “punctuated” attacks that will last for several hours or several days.

M.2 vs. PCIe (NVMe) vs. SATA SSDs: What’s the Difference?

There are many types of SSDs (solid state drives) and it can be overwhelming when deciding which SSD to purchase for your next storage upgrade. The good news is, SSDs are more affordable than ever and in this blog, we’ll break down the major differences between M.2, PCIe NVMe and SATA SSDs.

The CPU

The CPU, or Central Processing Unit, principal part of any digital computer system, generally composed of the main memory, control unit, and arithmetic-logic unit. It constitutes the physical heart of the entire computer system; to it is linked various peripheral equipment, including input/output devices and auxiliary storage units. In modern computers/ mobiles, the CPU is contained on an integrated circuit chip called a microprocessor.

The control unit of the central processing unit regulates and integrates the operations of the computer. It selects and retrieves instructions from the main memory in proper sequence and interprets them so as to activate the other functional elements of the system at the appropriate moment to perform their respective operations. All input data are transferred via the main memory to the arithmetic-logic unit for processing, which involves the four basic arithmetic functions (i.e., addition, subtraction, multiplication, and division) and certain logic operations such as the comparing of data and the selection of the desired problem-solving procedure or a viable alternative based on predetermined decision criteria.

Honeypot

In computer terminology, a honeypot is a computer security mechanism set to detect, deflect, or, in some manner, counteract attempts at unauthorized use of information systems. A honeypot can be modelled after any digital asset, including software applications, servers or the network itself. It is intentionally and purposefully designed to look like a legitimate target, resembling the model in terms of structure, components and content. In computer terminology, a honeypot is a computer security mechanism set to detect, deflect, or, in some manner, counteract attempts at unauthorized use of information systems.

How COVID-19 has pushed companies over the technology tipping point—and transformed business forever

In just a few months’ time, the COVID-19 crisis has brought about years of change in the way companies in all sectors and regions do business. According to a new McKinsey Global Survey of executives, their companies have accelerated the digitization of their customer and supply-chain interactions and of their internal operations by three to four years. And the share of digital or digitally enabled products in their portfolios has accelerated by a shocking seven years. 

Nearly all respondents say that their companies have stood up at least temporary solutions to meet many of the new demands on them, and much more quickly than they had thought possible before the crisis. What’s more, respondents expect most of these changes to be long lasting and are already making the kinds of investments that all but ensure they will stick.

Rushed digital transformation is creating security risks

The pandemic provided the kick in the pants that many enterprises needed to finally get long-gestating digital transformation efforts underway. But for many organizations, such transformations turned into rush jobs, with many digital transformation projects being hatched far earlier than expected.

While some of these transformations came out in one piece, many weren’t so fortunate, carrying with them a virulent case of cybersecurity vulnerabilities. These vulnerabilities have in turn led directly to a surprising number of breaches.

How consumer IoT devices can break your security

The Internet of Things was never conceived with the needs of enterprise security in mind. Then again, no one expected most of the world to leave their offices overnight and begin working from home.

But now, in a world where nearly 75 per cent of global enterprises expect at least some of their employees to continue working from home permanently, the potential threat of unsecured consumer IoT devices is taking on a whole new dimension.

“Almost everybody already had some remote access capability,” says Jon Green, vice president and chief security technologist at Aruba, a Hewlett Packard Enterprise company. “It was just that only a minority of employees were using it. Now, it’s the majority. So it didn’t fundamentally change architectures all that much, but volume got much, much higher.”

The fundamentals of security incident response—during a pandemic and beyond

Information security is a nonstop race between you and cybercriminals—and COVID-19 means more challenges for your organization and more opportunities for attackers.

We spoke with cybersecurity experts about the challenges a new remote workforce creates for organizations, how to respond to a cyber threat, and how the threats themselves are changing.

Semiconductors

A semiconductor is a computer chip that serves as the brain of anything that’s computerized or uses radio waves. It handles complex thinking such as arithmetic and data storage that is integral to cell phones, tablets, kitchen gadgets, laptops, video game consoles and automobiles.

In vehicles, dozens of individual semiconductor chips are used to control everything from engine temperature to alert drivers of the need for an oil change. The types of chips produced by semiconductor companies can be categorized in two ways(As per the integrated circuits or functionality of the chip).

Usually, chips are categorized in terms of their functionality. However, they are sometimes divided into types according to the integrated circuits (ICs) used.
