IAM is crucial to information security because without Authentication and Authorization, an information system would be incomplete. You must determine who has access to what data and to what level. If IAM is properly managed, enterprises will lower the risk of data breaches, which have a variety of negative consequences including reputational damage, legal problems, and financial loss. You can follow the six IAM best practices when you create your access management system:

Create a model with zero trust.

This concept is founded on the idea that neither users or applications, whether they are a part of your network or not, should ever be trusted unless they can be verified as legitimate. Users and applications will continue to be subject to security checks even after validation, recording activities and gauging levels of risk while they are connected to the network. This will make it easier to recognize odd network activity quickly and raise an alarm in circumstances where security precautions have been disregarded.

Use of Single Sign-On (SSO) and Multi-Factor Authentication (MFA) (SSO)

MFA strengthens system security by requiring users to use an extra authentication method in addition to their username, password, and PIN. This comes in the form of:

• Something you have e.g. smartcard
• Something you are e.g. fingerprint
• Something you know e.g. PIN

Users should only be allowed access to the content that is absolutely necessary for them to carry out their jobs. Everyone having access to everything will lead to disaster.

Reviewing user privileges and accounts on a regular basis

Perform routine audits of user credentials and responsibilities within your systems. This will guarantee that users who previously had access to privileged content but no longer require it have that access revoked. With the help of these periodic audits, you can also make sure that users aren’t granted access that isn’t legally theirs, and you can always grant users more access as soon as they request it.

Comply with the Compliance Requirements

To control how data is handled at the organizational level, you must develop cybersecurity rules and regulations. Additionally, you must make sure that you adhere to international recognized compliance frameworks, such as the Health Insurance Portability and Accountability Act (HIPAA), the General Data Protection Regulation (GDPR), the International Standards Organization (ISO) frameworks ISO/IEC 27001 and 27002, and the US National Institute of Standards and Technology (NIST) Framework for Improving Critical Infrastructure Cybersecurity (NIST CSF)

Use of Strong Passwords

A good password should be simple to remember yet extremely challenging to decipher. The National Institute for Standards and Technology (NIST) advises that a strong password have the following characteristics:

• At least eight characters long;
• Have special characters
• Avoid using sequential or repetitive characters such as 1234 or aaaa
• Avoid passwords that are specific a person’s situation/circumstance, such as a person’s name
• Avoid common passwords such as P@ssw0rd
• Restrict the use of old passwords to avoid using credentials that may have been exposed in a data breach
