Identity and Access Management (IAM) is a system that allows businesses to manage user identities, rights, and access to numerous systems and applications in a safe manner. It serves as a gateway to secure an organization's resources and data by limiting who can and cannot access them. IAM systems also enable enterprises to monitor and audit user access, ensuring that all access adheres to defined policies and procedures. IAM also assists firms in meeting compliance and security regulations such as GDPR, PCI DSS, and HIPAA. User accounts, authentication, and authorization may all be managed using IAM solutions. They can also be utilized to enable single sign-on (SSO).allowing users to access various systems with one set of credentials.

03. Encryption of Data

Data encryption is the process of converting plain text into unreadable ciphertext using an algorithm or cipher. It is a vital security mechanism for preventing unwanted access, alteration, and disclosure of data. Data kept on computer systems, transported over the internet, and saved on mobile devices may all be encrypted. It's also used to safeguard data saved on removable media like USB devices and CDs. Encryption is an important component of any information security program, and it is used in conjunction with other security measures to protect data confidentiality, integrity, and availability.

04. Network Surveillance

The technique of continually monitoring an organization's networks for any anomalies or changes that might signal a security breach or other malicious activities is known as network monitoring.
