In a world where more and more aspects of our lives are connected and online, especially our work, companies must adopt the proper measures to secure their networks and users’ data. Learn more about Zero Trust Network Access (ZTNA) in this article.

What are its advantages? How to set it up? But why is it a more relevant security solution than a traditional system? Let’s go!

What Exactly Is ZTNA?

Zero Trust Network Access, often referred to as  ZTNA, is a security concept that emphasizes the importance of consistently verifying the identity of users and devices before granting them access to an organization’s network resources.

In a zero-trust environment, the network is presumed to be compromised, and all access is carefully managed and prohibited (whether the access request comes from inside or outside the web).

Since ZHENA’s philosophy is “never trust, always verify,” all network traffic, including that which originates from the network itself, is considered to originate from an untrusted source. This contrasts with traditional security models, where traffic from inside the network is assumed to be trusted, and only traffic from outside the network is scanned.

How Can Businesses Take Advantage Of ZTNA?​

To execute ZTNA, organizations frequently utilize a few distinct innovations, including the accompanying:

1. Multifaceted verification (MFA). It is a strategy for safeguarding a framework or organization that expects clients to give more than one yet numerous types of character before getting to the safeguarded asset.
2. By requiring unapproved clients to give numerous types of validation ( two-factor verification, single sign-on, information factor confirmation, ownership factor validation, biometric factor validation, and so on), the objective of MFA is to make it more challenging for clients to get to delicate data without approval.

Personality and access to the board (IAM). It is a bunch of safety practices, and innovations used to oversee computerized characters and limit admittance to organize assets and applications. IAM, which can be separated into a few critical parts like the personality of the executives, confirmation, approval, or access control, assists associations with guaranteeing that main approved clients can get to the information. 

Touchy information and frameworks can perform activities for which they are authorized. Controlling who approaches what and guaranteeing the ideal individuals to come to the perfect assets at the ideal time are basic IAM steps that ensure an association and its information stay consistent. Also, secure.

1. Network division. It is the method involved in isolating a PC network into a few more modest and safer organizations. VLAN division, subnetting, and miniature division are various ways of dividing an organization.

By dividing an organization, organizations can restrict the degree of harm caused on the off chance that their organization’s security is penetrated and limit the extent of an assault’s expected effect. Likewise, they can direct admittance to delicate information and frameworks, guaranteeing that main approved clients can get to them.

1. Cloud Access Security Merchant (CASB). Security programming gives permeability and command over cloud utilization by mediating an association’s clients and cloud administrations. The security highlights presented by the CASB permit, specifically, better control and permeability of the cloud administrations utilized and superb insurance of administrations and information on the cloud.

The CASB was evolved to assist organizations with utilizing cloud benefits and shield themselves from the perils presented by distributed computing. It may be given to clients as help or as programming that should be downloaded and introduced locally.

Conclusion

Using ZTNA, businesses can better protect their network and critical data from external and internal threats. Zero Trust Network Access is therefore becoming more common as companies move towards cloud and SaaS services, as it can provide better breach protection and minimize the attack surface.

It is, therefore, a much more suitable option than a traditional system for all companies that work remotely or whose activities are distributed worldwide (especially in the face of the increase in cybersecurity threats and their complexity).

To guarantee the general operations of companies against cyber threats, it is essential to activate operational resilience, acquiring tools to act before, during, and after an attack. To counter the increase in cyberattacks and their business consequences, many organizations are adapting their disaster recovery procedures with measures to respond to these types of incidents.

However, these procedures have remained almost unchanged for years, proving inadequate against today’s threats. The key finding is that, at an enterprise level, disaster recovery is only one aspect of a more extensive scope: operational resilience. 

What Is Meant By Operational Resilience?

Operational resilience is a comprehensive concept that ranges from governance to active risk management through business continuity plans and the management of risks deriving from cyber attacks, data protection, and third-party suppliers. On the other hand, disaster recovery is a very specific action and refers to a limited period of time.

In other words, disaster recovery plans are mostly about the recovery itself. While operational resilience implies a broader perspective, covering the entire ecosystem and every possible measure to ensure business continuity during attacks or other types of adverse events.  

Strengthen The Weak Links In The Chain

Operational resilience has a scope that requires the participation of all departments and members of an organization. It cannot be the exclusive prerogative of a team, but must involve everyone, from management to the board of directors, up to the staff. Whoever has management roles must know what the risks are and how much the company is exposed or able to bear them. 

For this, functions and procurement agreements must be set up with third-party suppliers. Resilience needs to revolve around day-to-day workflows, and if more than one vendor is necessary to manage risk, then you need to diversify providers. In today’s landscape, we are all targeted: companies, suppliers, partners and providers. If a threat were to compromise or bring down a vendor’s systems, companies that depend on them could also experience problems .

Focus Resilience On Operations

The US Department of Transportation has proposed a $1 million fine against Colonial Pipeline for ” control room management errors ” during the 2021 cyber attack that caused the gas supply disruption on the east coast of the United States. The fine is in addition to the revenue losses from the attack itself. 

According to the US government, the company did not act from an operational resiliency perspective : instead of planning how to handle and limit the scope of an incident, it simply shut down process control networks as soon as the malware went into action.  

Companies administering national infrastructure or critical supply chains should think more about business continuity management and controls to mitigate risk. Everything must start from the awareness of the risk profile and the planning of adequate measures to manage it.

Why It’s Essential To Bring IT Closer To OT For Operational Resiliency

One of the main causes of conflict in the industrial sector – and the reason why operational resilience initiatives fail – is due to the lack of interaction between information (IT) and operational technologies (OT).  The respective departments need a clearer understanding of each other’s challenges and workflows. This situation must change, starting with the adoption of a new perspective. 

Part of the problem is that cyber threats are seen as something unto themselves. They are a risk to the security team or IT department and so others can wash their hands of it.

However, this myth must be debunked. Only with the proper understanding of the flows of the various corporate teams and with a shared assumption of risks can adequate resilience measures be implemented.

Active Directory With A View To Operational Resilience  

Active Directory and Azure AD in hybrid identity environments play a central role in building operational resilience. Even though there is now a tool to manage priorities between departments, we often need to remember how important Active Directory is. Nothing can be done without Active Directory, it is the heart of business activities, therefore it should not be considered as a separate program, but must be integrated into the operational resilience strategy.  

An Active Role In Operational Resilience 

Calamity recuperation plans zeroed in on catastrophic events should be fitter to address the present dangers to functional versatility. Since the personality framework is significant to business coherence and is the essential objective of digital assailants, it is fundamental to safeguard it. To keep functional flexibility from being compromised, associations should put the safeguard of the personality framework first.

5G is not a new technology: we have talked about it often. Let’s see what changes instead in the use of frequencies. After the assignment under license by the Ministry of Economic Development (MISE) of the frequencies for setting up the new 5G networks ( 5G frequencies: the auction ends with great success for the state coffers ),

the telecommunications operators assigned started to gear up for territorial coverage: TIM and Vodafone will soon share their respective towers to provide 5G connectivity.

As repeatedly highlighted, 5G is not a new technology but a more modern and optimized version of the technologies we have already used for some time. 2G peeked out in India around 1993. Thanks to GSM, it was possible to start transferring digital signals, gradually putting aside the previous analogue transmission technology, which became widespread in the mid-1980s and matured with the TACS standard and its analogue.

The fifth-generation networks differ from 4.5G for the new NR radio interfaces ( New Radio ) and the latest coding, multiplexing and error correction systems ( Filtered OFDM, Sparse Code Multiple Access, Polar Codes and so on ). Among the primary objectives related to implementing 5G networks are developing models for digital services offered by telecommunications operators in partnership with utilities, public administrations, businesses and OTT ( over-the-top ) subjects, such as li defines AGCOM.

Therefore, as we have seen in the 5G articles, what is it, how does it work and when will the terminals be compatible, and is 5G dangerous? All hoaxes, or can there be something true? 5G networks will use optimized versions of improved multi-carrier modulation transmission techniques, more advanced information engineering tricks and, as mentioned above, so-called polar codes.

The latter is the first channel coding system in the world that approaches the threshold of the Shannon limit or the maximum speed at which data can be sent, on a particular frequency band, maintaining an error rate equal to zero. Polar codes (Turkish inventor Erdal Arikan was awarded last year by the founder of Huawei) allow data to be transmitted more efficiently by optimizing encoding performance on 5G networks and speeding up performance.

Arikan thanked Huawei’s engineers, noting that with their cooperation, his ideas could have come true (and been implemented to advance wireless communication technologies) in just ten years. Compared to previous generations, we said that 5G is a technology introduced previously that raises question marks. If anything, it uses portions of the frequency spectrum not once used for data transmission on the mobile network (but already used for other services) from 24 GHz upwards.

As the frequency increases, the wavelength becomes shorter. Wireless devices that transmit and receive the signal can transform it into data using particular modulations. By transmitting at low frequencies, the wavelength is broad so that the modulation operations occur at the speed of a snail (small bandwidth, slow network). As expected, by increasing the frequencies, the transmitting and receiving devices can communicate much faster (greater bandwidth, much faster data exchange).

The speed of all electromagnetic emissions is understood as the distance covered in the unit of time is always the same regardless of the frequency. The problem is that higher frequencies are much less “penetrating” and fail to overcome obstacles. They are also much more vulnerable to weather conditions with data reception which can become arduous if possible.

5G networks will be able to use a mechanism called adaptive beam switching that will allow devices to quickly jump between one frequency band and another, choosing those that, in real-time, prove to be more reliable and efficient. Otherwise, transmitting even at higher frequencies would be only helpful if you risked an unstable link and unreliable data transfer.

As a result of the tender launched by the Ministry of Economic Development, mobile telephone operators in Italy obtained the rights to use frequencies on three distinct bands to set up the new 5G networks: 694-790 MHz, 3600-3800 MHz and 26.5-27.5GHz. The first two represent nothing new compared to the previous generation networks: think that the first ones are the same ones used for digital terrestrial.

A summary table of occupancy for each generation’s mobile phone networks :

1. 5G : 700/3700 ​​MHz and 26 GHz (26,000 MHz)
2. 4.5G: 1500 MHz
3. 4G : LTE FDD-LTE 800/1800/2600/2100 MHz
4. 3G: HSDPA WCDMA 900/2100 MHz
5. 2G : GSM 900/1800 MHz

As far as the 26.5-27.5 GHz block is concerned, there is still no mention of millimeter waves (for the latter, we refer to the portion of the spectrum between 30 and 300 GHz and are so-called because their wavelength varies between 1 and 10 millimeters) and will be frequencies used by operators, at least for the moment, only in places with a high traffic density such as city centers, stadiums or industrial plants to provide very high-performance connectivity.

In fact, for this last block, there were very few offers in the auction because in an initial phase, after the first deployment of 5G networks, it is legitimate to assume that the 26.5-27.5 GHz band is used only to establish links over long distances with perfect optical visibility. In terms of emission power, nothing changes, and the value of the field cannot exceed the legal words (in Italy, equal to 6 V/m even if some operators are asking for it to be raised: Wind Tre: India increases the law for the RF fields generated by mobile phone masts ).

Frequencies above 24 GHz will be used for 5G to set up small cells. With the fifth generation network, a further aim is to achieve the convergence between fixed and mobile users, all connected via radio to 5G. In this regard, the small cells located throughout the territory (increasing the number of antennas will reduce emissions; with 5G, moreover, the transmission does not occur 100% of the time as occurs in the case of 4G…) will allow the use – in optimal conditions – of wireless connections in the order of 10 Gbps (the same direction in which the WiFi Alliance is looking with WiGig : WiGig: what it is and how the technology that will work alongside WiFi 6 or 802.11 axe works ).

In the article 5G inside buildings: here is the technology for ultra-fast indoor connections we gave an account of the work carried out by JMA Teko in collaboration with the University of Bologna to bring 5G at very high speed to closed and densely populated spaces.

Have you ever heard about Deep Learning, Machine Learning, Artificial Intelligence, or that machines will dominate the world?

Yeah, robots like the Terminator may be closer to our reality than you think! But don’t be afraid!

This is a theme on the rise in the technical areas of technology study and our daily life, which is why we must always be informed and aware of the constant innovations of this vast universe.

What Is Deep Learning?

Deep Learning, or Deep Learning, translated into Portuguese, is one of the branches of Machine Learning; it is a machine learning that trains computers to perform human tasks naturally from artificial neural networks.

This is a topic on the rise within Artificial Intelligence (AI) and has allowed analysis of large volumes of complex data from Big Data, rapid identification of problems, and optimization of decisions.

Instead of using algorithms with predefined equations, deep Learning adjusts basic parameters so that the computer can learn by recognizing patterns in several layers of processing.

Did you know that this technology is also present in your daily life?

Neural networks are capable of processing a large amount of data. Based on our online actions, they can learn about our purchase preferences, series, and music and make better suggestions on platforms such as Amazon, Spotify, and Netflix.

Why Use Deep Learning?

With computing advances, access to the cloud, and better processing units, we produce much more data than ten years ago. Analyzing this data so that it becomes our allies is a high-performance task.

The artificial neural networks implemented in the learning layers of Deep Learning can examine this information more effectively and efficiently than traditional methods. See some of the advantages of the technique.

Efficiency

With deep Learning, neural networks can process and optimize high data rates efficiently and much faster. Time spent on modeling, engineering resources, and data processing is significantly reduced.

Assertiveness

Deep Learning performs its Learning through pattern recognition, analyzing a high amount of information. It is capable of correcting and improving itself, thus achieving super high success rates, with error rates below 10-5. That means having one error in every 100,000 samples!

This can be compared to the Sigma quality level. In this case, it is possible to achieve assertiveness capable of fitting into the 6 Sigma level (3.4 defects per million) of the Six Sigma Methodology.

Understanding Of Customers

We generate a database of our preferences with each click we make. Deep Learning allows large companies, which already see technology as an ally, to process this data to customize service and customer service. It is possible to know what to suggest to customers, especially when.

Failure Prediction

Processing complex data efficiently and assertively, learning and adapting autonomously, Deep Learning allows for automating processes and predicting failure patterns. Knowing when an error will occur in your production is an excellent ally in market competitiveness and reducing production costs.

Now that you know the benefits of Deep Learning let’s see some examples of applications.

Examples Of Applications In Everyday Life

Are we too far from the Machine Revolution, or that we have privacy on the net?

I’m sorry to inform you that no, but that’s not necessarily a bad thing.

See some examples of how Deep Learning is present in our daily lives, often helping us without our noticing.

• Security: The facial recognition we use to unlock our cell phones is one of the main functions of Deep Learning. It has been essential for the development of remote devices and also for police use in fugitive and wanted recognition.
• Voice assistants: Assistants like Alexa and a are purely developed with Deep Learning. Its ability to pick up on our preferences, detect our voices and understand our requests are results of Deep Learning.
• Health: Just as Lean Healthcare impacts reducing waste and quality in Healthcare, systems developed with Deep Learning have helped doctors in detecting diseases such as retinas affected by diabetes and detecting cancer cells.

In addition, platforms like Netflix and Spotify can also analyze your content preferences for future suggestions, such as series and playlists.

Artificial Neural Networks

Artificial Neural Networks are computational models analogous to the human brain’s neural connections capable of performing machine learning, Machine Learning, and pattern recognition (Pattern Recognition).

These models consist of systems of connected neurons. They are composed of an input layer to receive the signal. This output layer decides the input, and between these two, an arbitrary number of hidden layers are the exact computational mechanism of the network. With a hidden layer, it is possible to approximate any continuous function.
