Advanced Server Access is a relatively new aspect of identity and access management system for the cloud. In fact, it fits better under the umbrella of privileged access management (PAM). PAM is built on top of IdPs and ADs, which are crucial for identity and access management for on-prem networks. By being used in conjunction with ADs, PAM has been able to successfully provide enhanced control over identity for administrators and other privileged users.
What is PAM?
Privileged access management helps to secure and control privileged access to critical assets on an on-premise network. With PAM, the credentials of admin accounts are placed inside a virtual vault to isolate the accounts from any risk. Once the credentials are placed in the repository, admins are required to go through the PAM system every time they need access to the critical areas of a network. For every single login, their footprint is logged and authenticated. After every cycle, the credentials are reset, ensuring that admins have to create a new log for every access request.

“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.

A brute-force attack is a type of cybercrime which involves automated hacking activity using bots. The primary aim of a brute-force attack is to crack a password in order to gain access to a user account in an unauthorized manner. Using the automation tool, an attacker repetitively attempts different alpha-numeric combinations at considerable speed – thousands per second – until the user’s password is determined and the account is unlocked.
With the advent of the cloud and the rapid innovations in technology, a brute-force attack has emerged as one of the most common types of outsider attack against web applications.
Here are three steps that will go a long way in improving the security of your network against brute-force attacks:
Enforce a strong password policy
A password is the first line of security when it comes to preventing unauthorized access. A strong password policy, therefore, can ensure that your users set up passwords that are strong and not easily compromised. Here are some important aspects you can regulate by setting up a password policy:
Password Length
A brute-force attack typically works by continuously trying every possible combination using numbers, letters and special characters. The shorter the password length, the fewer the combinations and the easier it is to crack. If the password length is known (or is fixed), again, it becomes easy for the attacker to attempt combinations of that particular length, although it will take longer depending on its length.
Password Complexity
A dictionary attack is a subset of the brute-force attack, which attempts to crack a password by trying all English words and then trying them with multiple combinations of other words and numbers. If users are setting simple passwords because they are easy to remember, they will also be easier to crack.
Password Expiry
Periodically, the system must prompt the user to change their password so that any possible ongoing attack can be effectively guarded against. Moreover, this practice will also mitigate undetected breaches of privileged accounts.
Use multi-factor authentication
Multi-factor authentication puts an additional layer of security between the brute-force attacker and your data. With MFA, even if the password has been correctly identified by the bot, the attacker will be unable to proceed because the system will require either an OTP or a confirmation from a different device (such as a smartphone app).
Another way to set up an additional layer of security at the login point would be to use a captcha – a box showing warped text or images and require manual entry of a response. This will effectively keep out a bot that is executing automated scripts.
Set up an account lockout policy
Set up a policy wherein you can detect and block suspicious login attempts. Locking an account after three failed login attempts, or attempts to login from a different country or an unlikely hour can prevent intruders from entering into the system. To resume work, the authorized user will need to seek administrator intervention to unlock the account.
You can also set up a progressive delay lockout wherein an account is locked for a fixed period of time after a certain number of failed login attempts. The lockout period can progressively increase with the increasing number of failed attempts and helps keep out brute-force attack bots long enough to make them ineffective.

As organizations increasingly place their data and applications across multiple locations on the cloud, zero trust security is rapidly gaining ground as the network security model of choice among enterprises.
Zero Trust Security is a security model in which a user, irrespective of whether he/she is within or outside the network perimeter, requires an additional verification to get access into a network. There is no particular technology or software product associated with this security model. It simply requires an additional security layer to verify users. This could be anything from biometric verification like thumb-print scanning, or a digital signature verification. Of the two, biometric verification is preferable as it can neither be recreated nor hacked.
Traditionally, organizations have been using what is referred to as the castle-and-moat approach to network security. In this model, the network is the ‘castle’ which is protected by security solutions as a ‘moat’. With this approach, part-of-the-network users were blindly trusted and allowed to enter the castle. However, as companies grew, their data and applications grew with them and the need to split them and store them in multiples silos rose. It also became easier for hackers to gain entry into a “protected” network by accessing a single user’s credentials.
Instead of the castle-and-moat model, adopting the zero trust security model and adding an additional layer of security to a network has been shown to prevent instances of data breaches.
Principles behind zero trust security
1. Trust no one: The model assumes that all the users of the network are potential attackers and hence, no users or systems are to be automatically trusted.
2. Least-privilege access: The users are given access based on a need-to-use basis and nothing more. This can eliminate each user’s exposure to vulnerable parts of a network.
3. Microsegmentation: The entire network is split into segments, each with its own authentication process.
4. Multi-factor authentication: Access to the network requires additional evidence that the user is legitimate.
The network of an organization is its gold mine and most organizations are increasing their spend on network security. Implementing a zero trust security model can go a long way in protecting your network from breaches.

Privilege abuse – that is the security threat that your business’s IT team is most worried about. According to a survey conducted in March 2014 among more than 4000 IT security executives, over 88% of them fear that users who have access to the organization’s applications and data are the ones who are most likely to compromise it and lead to a security breach.
Privilege abuse, or privileged user abuse, refers to the inappropriate or fraudulent use of permitted access to applications and data. This could be done, either maliciously, accidentally or through ignorance of policies. In addition to causing financial losses, such insider breaches also damage the organization’s reputation, sometimes irreparably.
War seems to have taken a new form in the Information age. Large corporations have reported increased data breaches in the last couple of years and the number is all set to increase in 2019.
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.
