Agent-based Cloud Security Solution? No thanks!
If your organization relies on the cloud for a majority of its operations, you may want to look closer at the type of architecture your security solution uses – whether it is agent-based or agentless. While some might say that it is irrelevant and that you should focus only on the security solution’s efficiency, we beg to differ. Picking the right kind of cloud security solution can drastically affect your organization’s day-to-day operations and how much ownership you can take over the security solution.

Beware of Credential Stuffing
In recent times, you might have noticed user accounts being compromised by the millions, and yet companies refute these claims saying that their systems are secure and have not been attacked. In these cases, the companies are right – instead of a direct attack, the hackers may have performed an attack called ‘credential stuffing’. In this type of attack, hackers get their hands on usernames and passwords of one application or service and stuff the same credentials on another login for another digital provider.
For example, if you have used the same user ID and password for creating your Facebook and Twitter accounts, a hacker who has access to your Facebook user id and password can use the same for getting into your Twitter account. This does not mean that Twitter’s systems are faulty. It simply means that your credentials have been stuffed. Credential stuffing attacks use code injection techniques to test the credentials against multiple accounts like social media, online marketplaces, and bank accounts. Once access is gained, the hacker can get access to personal information, credit card information and other personally verifiable information.
In recent times, this type of attack has gained popularity due to the fact that most users use the same user ID and password for multiple accounts. The situation right now is precarious for most online users – a recent breach of breaches has given hackers access to a whopping 2.2 billion user IDs and passwords. It is called a ‘breach of breaches’ because a few hackers hacked into millions of Dropbox and LinkedIn accounts and compiled a list of plain text credentials. However, another team of hackers hacked into this list to compile an even bigger list of stolen credentials.
If you have built enterprise applications, how sure can you be that your users have created different passwords for all your applications? There is no way for you to know for sure. However, you could put in place a password policy which prevents them from using the same password for all the applications in your network.
Akku from CloudNow Technologies allows you to set custom password policies to help you standardize the passwords set by your users. You can also leverage it to prevent the setting of the same passwords. To know more, get in touch with us now.
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.

Why is multi-factor authentication indispensable?
Ever heard of the butterfly theory? A single flap of a butterfly’s wings in Australia has the potential to cause a tsunami in Indonesia. Similarly, a minor tweak in your IT infrastructure has the potential to make every node of your network vulnerable to serious attacks, irrespective of their relationship. To ensure that network security remains as streamlined as possible through any number of changes to your IT systems, it is crucial to add a virtually unhackable component to your network security.

The IAM Imperative: Through An SMB’s Eyes
Today’s MNCs were once small or medium businesses (SMBs). Small and medium businesses are the proving ground for emerging technology, as they have tight budgets and require specific, targeted functionality that suits their style and processes. Once products and solutions pass this litmus test, they start becoming more mainstream, being absorbed more widely by companies and consumers.
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.
