Zero Trust Security

June 7, 2021

Malware and ransom attacks have the potential to seize a thriving business and can put its
future in jeopardy. Such attacks can extract sensitive data and can misuse it to a greater extent.
Cybercrime is a constant threat, and it is well known to target data related to private credentials
and financial transactions.
Reputational damage is extremely harmful to an enterprise as it loses trust resulting in loss of
customers and stakeholders. It is important to ensure the data is protected at all costs, and
databases must be fortified with better security layers to avoid such data penetration. Loss of
intellectual property can be used by organizations to completely wipe out competitors by
exposing trade secrets, R&D development, and much more.
Traditional security systems were built on a common ideology, everyone inside the network is to
be trusted by default. This is where the attacker gains leverage, and they create an access point
over everything inside.
This is where zero trust comes into place. An IT security model creates a framework that
requires identity verification for every person trying to access a secured database. Instead of
creating a complete firewall, the zero trust model focuses on verifying each inbound request and
finding out its origination source.

How to implement Zero Trust security architecture in the Cloud?

Define and address the current status of the network, database, assets, applications, and
services related to the organization. Review and weigh all the risks and exposed areas and
assess the organization’s current security status.
Prioritize the most critical aspects of the organization and ensure that they are graded with the
highest level of security encryption.
Create a layout of all the assets and their transaction flow to determine where the sensitive data
lives and which users are constantly accessing it.
Review and restructure all the security protocols and remove/replace the outdated local legacy
systems.
Build a list of cloud services available for the organization and maintain strict access to from
high to low-risk services.
Maintain less exposure by removing stale accounts and constantly updating access logins by
rotating passwords.
Invest in resources and cloud security models that can be constantly upscaled to adapt to new
threats and support the organization’s changing needs.

Steps to implement Zero Trust Security on Cloud
Protect the customer’s data:

It’s the core value of the zero-trust system to implement strict controls on user access, zero-trust
limits the access for users to get bare minimum privileges. Users are granted permission to
read, write or execute files, which helps monitor their jobs and activity.
Just like users, devices can be compromised and cannot be trusted blindly to save data identity-
centric control features must be deployed from end-to-end. This helps keep the devices and the
data safe at bay by timely verification and ensuring that the internal resources are up to the
security requirements.
Deploy preventive measures-
Multifactor authentication is essential towards achieving zero trust, and it helps minimize risk by
detecting any anomalous traffic.
Review all accounts at regular intervals to ensure they are secure and grant the users limited
access to track sensitive data access.
Monitor the network continuously, figure out the loose ends. Inspect those areas, deploy
countermeasures and keep track of all the unusual behaviors and the authentication logs
related to them.

Reduce the complexity of the security stack

Implementing security systems with legacy devices is quite expensive and unnecessary; avoid
that with a cloud-based approach where the complexity is eliminated. The cloud automates all
the deployment, monitoring, troubleshooting, and patching processes. Helping organizations
scale as and when required.

Increase visibility

Increased visibility allows more room for perfection and helps identify the real threats to the
system by indirectly improving network visibility. Better authentication and authorization
screening have helped minimize costs and security staff.
Implement machine learning and artificial intelligence technology to optimize the performance
based on current and real user behavior.

Micro-segmentation

Zero trust networks utilize this method to break down the security zones into small perimeters to
provide separate access points to the network. This creates multiple secure zones across
multiple devices and data centers, indirectly increasing security layers and improving the
network.
A user without access to any of the zones would be restricted to other zones and enter only with
a newly issued access code by the administrator.

Adopting Zero Trust Security Model in the Cloud

There are 4 stages to adopt the zero-trust model
Verification of identity
Verification of device
Verification of access
Verification of services
By implementing a zero trust model, organizations can build a secure chain of networks and
decrease their chances of exposure over time by preventing attacks and eliminating
unauthorized access.

Conclusion

Each organization needs to figure out the approach to create a sustainable environment best
suited for their needs. By balancing risk profiles and improving access methods to gain entry to
their company resources, one can increase investments in zero trust. Businesses can greatly
benefit from cloud migration and zero trust architecture by improving user experience.

A Complete Guide To Customer Acquisition For Startups

Any business is enlivened by its customers. Therefore, a strategy to constantly bring in new clients is an ongoing requirement. In this regard, having a proper customer acquisition strategy can be of great importance.

So, if you are just starting your business, or planning to expand it, read on to learn more about this concept.

The problem with customer acquisition

As an organization, when working in a diverse and competitive market like India, you need to have a well-defined customer acquisition strategy to attain success. However, this is where most startups struggle. Now, you may have a great product or service, but if you are not in the right place targeting the right demographic, you are not likely to get the results you want.

To resolve this, typically, companies invest, but if that is not channelized properly, it will be futile.

So, the best way out of this dilemma is to have a clear customer acquisition strategy in place.

How can you create the ideal customer acquisition strategy for your business?

  • Define what your goals are

You need to define your goals so that you can meet the revenue expectations you have for the current fiscal year. You need to find a value for the metrics –

  • MRR – Monthly recurring revenue, which tells you all the income that can be generated from all your income channels.
  • CLV – Customer lifetime value tells you how much a customer is willing to spend on your business during your mutual relationship duration.  
  • CAC – Customer acquisition costs, which tells how much your organization needs to spend to acquire customers constantly.
  • Churn rate – It tells you the rate at which customers stop doing business.

All these metrics tell you how well you will be able to grow your business and revenue.

  • Identify your ideal customers

You need to understand who your current customers are and who your target customers are. Once you are aware of your customer base, you can focus your energies in that direction and get the maximum sale of your products or services. You can also understand what your customers require through various analytics and markers and address them to leverage your products/services towards them.

  • Choose your channels for customer acquisition

How will you acquire customers who will eventually tell at what scale and at what rate you need to expand your business? You could market and sell your products on social media channels like Instagram, Facebook and YouTube, or invest in paid marketing like Google Ads. You need to develop a unique strategy for each of these channels. 

  • Communicate with your customers

If you know exactly what your customers have in mind, then you will be able to develop your customer strategy with a clear perspective in mind. You can do it through surveys or customer opinion forms, email contact forms, blog posts and social media posts. After that, you just need to measure the analytics, clearly understand the insights, and improve your strategy accordingly.

Combining these strategies with your long-term business plan will bring results. However, there will be challenges on the way, where you need to adapt as per the requirements to make the most of it. At the same time, introducing new technologies like AI and ML can also solve such issues easily.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

  • Highly calibrated cameras that take a photograph of the image from various angles.
  • Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

  • Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

  • Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

  • Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

  • Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

  • Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

  • 3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
  • It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
  • They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
  • It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
  • It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning   is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

  1. Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
  2. Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
  3. Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
  4. Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.  

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.
