Hashing And Salting – The What And How

“irgvctxmsr” – sounds like gibberish, doesn’t it? But if you were to decrypt this string using a mono-alphabet shift cipher where each letter has been shifted to the right by 4 numbers, you would see that it spells “encryption”!

Protecting critical data and information by encrypting them was first performed by Julius Caesar in 120 BC. The art of encryption has been through several modern shifts, and currently most of the data on the internet is protected using sophisticated encryption algorithms like AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adlemen), ECC (Elliptic Curve Cryptography) and PGP (Pretty Good Privacy).

Deciphering an encrypted message requires a key. Nowadays, messages are encrypted using public keys and decrypted using private keys. The private keys are shared privately between two trusted parties. Losing a private key can be disastrous, as encrypted messages can then be read by anybody with access to the private key.

Password Hashing

While encryption is a two-way function and is primarily done with the intention of being decrypted, password hashing is a one-way function. Hashing allows us to use a mapping function to map data of any size to a fixed length. The resultant output is called the hash value. Technically, hashing is reversible – however, the computing power required to get the original message makes it impossible for the original message to be decoded. Simply put, encryption protects the data in transit while hashing is used to authenticate the data and lets you know if it has been tampered with.

Here is how it works – consider that you have a digital document that you have digitally signed and uploaded to your website for another person to download. Now, you will run a hash function on the document and another one on your digital signature and encrypt the resulting hash values. Once a designated person downloads the document, the browser decrypts the hash values using a key and runs the same hash function on the document. If the resulting hash values are the same for the sender and receiver, it means the document and signature have not been tampered with.

Modern hashing algorithms include SHA (Security Hashing Algorithm), RIPEMD, WHIRLPOOL, and TIGER.

Salted Passwords

Salting is the process of adding an additional layer of security to the hashing process by adding a unique value to the end of the password and hashing the new password. By adding even one letter to your password and hashing it, you can change its hash value and make it harder for interceptors to find your password. For example, if your password is “V67gHD92”, you can add a unique character or string to the end of it and make it something like “V67gHD92SPICE”. Here, the word “SPICE” is called the salt.

Salting a password protects any data from brute force attacks in which bots attempt every possible combination of letters and numbers until the password is cracked. However, if the attacker knows your salt, the entire process of salting becomes worthless.

Can you Trust the Agent on your Active Directory?

If a company works with very few applications, user repositories would have to be mapped individually for each application. Every new user needs to be validated with each individual user directories to be able to access the respective protected application. This means that the same user has to log in separately every time he/she wants to use each application on the network. The inefficiency of this model was reduced greatly with the advent of Active Directory and LDAP.

A significant number of identity and access management solutions have the need to work with Active Directory as the repository of user information against which access is verified. Active Directory generally controls user identity and access permissions to everything from files, networks, and servers, to on-premise and cloud applications. However, integrating an Active Directory or LDAP with on-premise and cloud applications require third-party agents to be installed on your network.

To Filter or not to Filter YouTube Videos

A large percentage of employees in any organization use the internet for personal use during office hours. Their internet usage is mostly spread between YouTube, social media platforms and news sites. Of these, YouTube is by far the largest consumer of bandwidth.

YouTube is one of the largest online search engines on the internet – in fact it is second only to Google. Every day, over 5 billion videos are watched on the platform. What does this mean for an organization? Where should you draw the line when it comes to restricting YouTube content?

Why do you need to filter YouTube videos?

There are several ways in which operational workflow is disrupted due to a significant proportion of your employees spending time watching videos on YouTube. Especially with the newer generation of digital natives stepping into the workforce, the ramifications of unmoderated YouTube access are more pronounced. As a company, this could even result in the need to hire additional personnel to compensate for the loss of productivity. Here are a few ways in which unchecked YouTube access can harm your organization.

Reduction in efficiency

It is estimated that employees spend, on an average, one hour of their 9-5 workday browsing the internet. YouTube accounts for a considerable chunk of that time. If your company has around 20 employees, that amounts to a staggering 20 hours a day wasted on employees’ personal entertainment. On a weekly basis, that is 100 hours you can’t get back. If your organization is bigger, the problem scales as well.

While it can be argued that access to business-related YouTube channels can allow your employees to access solutions in a few minutes, YouTube is seen more like a leisurely and entertainment based “break”. Installing YouTube filter software can help to allow employees to access only whitelisted channels related to your business.

Load on internet bandwidth

The world is moving towards faster connectivity, and businesses which are faster to respond to their customers can deliver greater customer satisfaction. But the same high-speed internet is used by your employees use to browse YouTube too. This often amounts to several gigabytes of data, exhausting your internet bandwidth every month. Not only does this slow down your work communications, but assuming that you are billed on a monthly basis, imagine how much money can be saved by your company by reducing data consumption. Filtering YouTube videos can go a long way in reducing this burden.

Access to inappropriate content

YouTube comes with its fair share of shady content – pornography, religious extremism, and racial intolerance to name a few. Unmoderated access to a site with a large volume of such content can seriously dent the reputation of your organization. It can create moral conflicts between your employees on sexual harassment, religious or racial discrimination grounds. An office is no place to permit such activities.

The solution? A YouTube filter software!

With all this being said, it is crucial for companies to take a step towards controlling YouTube access on their networks. Akku from CloudNow Technologies comes with a highly effective YouTube Filtering feature which gives you control over what channels can be accessed by your employees and what cannot.

Meet GCP IAM: The Identity and Access Management Solution from Google

Google Cloud Platform (GCP) IAM comes as a free service that is available by default to all users of the Google Cloud Platform. GCP IAM is Google’s identity management console, enabling administrators of organizations to manage access and permissions provided to employees across the range of applications and resources that come as part of the Google Cloud Platform. The main function of the IAM is to grant specific users/roles with access to specific GCP resources and prevent unwanted access to other resources.

The fundamental building block of GCP IAM is an IAM Policy which answers the question of who (identity) has what access (role) to which data or applications (resource). This IAM Policy is made up of permissions, bundled into roles and matched by identities.

Let’s take a closer look at the concepts of identity, role, and resource as defined by GCP IAM, which make it a useful IAM solution.

Identity

A user’s identity can be accounted for through their Google account (assigned to an individual), Service account (assigned to a service related to the user’s role), a Google group (which can contain more than one Google/Service account), or a G Suite domain name (consisting of all G Suite accounts under a particular domain) or Cloud Identity domain (consisting of all G suite accounts under a particular organization) name.

Role

A role is a combination of permissions assigned to an identity. Traditionally, Google had what are now known as Primitive Roles – which were a standard set of 3 – namely, ‘Owner’, ‘Editor’ and or ‘Viewer’.

However, in GCP IAM, Google has gone not one but two steps further – with Predefined Roles and Custom Roles – in allowing administrators a wider range of options when it comes to assigning roles (and therefore, access to do less or more) to the organization’s resources.

With what are known as Predefined Roles, granular separation of duties, such as Instance Admin and Network Admin to name a few, is made possible. Custom Roles, as the name suggests, are roles which administrators can customize based on the organization’s needs.

Resource

As defined by Google, “resources are the fundamental components that make up all GCP services”, and include Cloud Pub/Sub topics, Compute Engine Virtual Machines, Cloud Storage Buckets, and App Engine Instances.

These resources can then be grouped into projects. Administrators can assign permissions based on different roles to identities in their organization in order to provide them with access to specific resources. On the other hand, they can also provide access to projects, which will then provide users with access to all resources under the project.

In the GCP hierarchy, a group of projects can also be placed under a team, teams can be placed under a department and departments can be placed under the organization. Administrators can decide the level of access they wish to give each user based on this hierarchy.

GCP IAM is great, but….

Despite the extensive control it provides to administrators, and the numerous possibilities in authorizing user access, GCP IAM has one downside.

Organizations today utilize a wide range of applications, not all of them being GCP resources. They may use a combination of resources from Amazon Web Services, IBM or Azure, to name a few, and GCP IAM does not support identity and access management on these resources. Its lack of capability to connect with on-prem identity providers such as Microsoft Active Directory and OpenLDAP is another major roadblock.

Looking for one IAM to manage them all? Try Akku, one of the best identity and access management solutions from CloudNow, that can help you manage identities across your on-premise and cloud-based applications seamlessly!

Akku – Secure your Enterprise Communication

Akku is a great way to control and authenticate communication channels for any enterprise.

One of the biggest threats to any organization is the possibility of a data breach, which can result in loss of data, loss of trust, and ultimately, loss of growth of the business. This makes data security a critical aspect to consider in any enterprise.

An important consideration, especially for SME businesses, is to secure their data – most companies still look for a way to do it in the traditional approach to data security – with an on-premise local environment.

Running the organization with an on-premise environment requires a dedicated workforce, this can be replaced with a secure cloud-based environment. But how does this fit in with Akku? Akku is a pure cloud Identity and Access Management solution that can be integrated with cloud, hybrid or on-prem applications.

So how can Akku help your organization?

Akku’s first great feature would be its Single Sign-on (SSO), where any enterprise’s user accounts and applications can be integrated into a single platform – making access easy for users and control easy for admins.

Unauthorized access is restricted by Akku, which is built on a certificate-based authentication architecture.

It is also possible to filter the content accessed by an organization’s users – DNS filtering to control websites that can be accessed, YouTube filtering to ensure only relevant video content is viewed, and even personal email blocking to improve productivity and security.

Akku also maintains highly granular logs, allowing for detailed reporting on user behavior – time, location, OS and so on for users logging in.

These are just a few of the functionalities that Akku brings to the table to add value to your organization’s data security.

So fight back against data breaches, and tell the world “My Data and Communication are secure!”

Is Your Data Secure? No…

As per a survey by Forrester Research (Forrester Consulting Thought Leadership Paper, February 2017), in the last 4 years, out of every three organizations, two have had an average of at least 5 breaches. There are nearly 6 billion data records that were stolen and lost in the past 10 years. According to www.breachlevelindex.com, an average of 165,000 records are compromised every hour. According to this article published on www.csoonline.com, global cybercrime related damage is expected to exceed US$ 6 trillion annually by the year 2021.

How can IAM help protect data?

Identification: Users make their claim on their identity by entering a username and verify through an authentication process
Authentication: Authentication may be a password or may rely on advanced technologies, such as biometric and token-based authentication
Authorization: The IAM system must then verify the user’s authorization to perform the requested activity and also ensure that users perform actions only within their scope of authority

Together, these three processes combine to ensure that specified users have the access they need to do their jobs, while unauthorized users are kept away from sensitive resources and information. Effective IAM solutions help enterprises facilitate secure, efficient access to technology resources across these diverse systems.

Identity and Access Management (IAM) is the information security discipline that allows users access to appropriate technology resources, at the right time. It incorporates three major concepts:

According to this article on BizTech magazine, improved data security is one of the three main reasons to deploy an IAM solution.

The article highlights the fact that consolidating authentication and authorization functionality on a single platform provides IT professionals with a consistent method for managing user access. And when a user leaves an organization, IT administrators may revoke their access in the centralized IAM solution with the confidence that this revocation will immediately take effect across all of the technology platforms integrated with that IAM platform.

So implement an identity and access management solution at your organization to take a major step towards improved data security.
