The Role of Access Control in Information Security

Business comes along with numerous challenges; running one is not an easy task and you need Security Access Control. If you’re unable to fulfill the challenging demands, it may result in disaster—one of the most crucial elements frequently overseen by companies in information security.

While starting a business or a company, one should always prioritize cybersecurity. If not done at the right time, damages can be severe. To protect your business’s data, financial and reputational, you must create a robust set of access controls in information security.

Access controls include limitations that serve as the first line of defense against cybersecurity threats. Below are what you’ll read on; you’ll come to know about access controls in information security, their importance, components, how it works, and how you can decrease the risk on access control information security.

Access Control and its importance in Information Security

We implement the security techniques in Access Control to regulate who/what can view/use the resources in your computer system. This concept helps in minimizing the security risk to the business. One of the essential components of security compliance is Access Control, and it ensures the correct placement of access control policies and security to protect the company’s sensitive information.

The two types of Access Control are Physical and Logical. Physical controls the access limits to buildings, rooms, and IT assets (physical), whereas Logical rules the connection limit to the computer networks.

If you want to secure your business, you can use access control systems. Access control systems rely on user credentials, auditing, tracks employee access to restrict them from accessing the business’s data centers. Access control minimizes the security risk by access the physical and logical systems in an unauthorized manner. 

Components of Information Security Access Control

Identification. 

For businesses, Identification is the first means of user verification. Identification consists of a universal naming system that includes the name of each employee. Employees in an organization adhere to the naming system that includes a user name/account number.

Also, each of the user names in the naming system should be Unique, Undisclosed, Free of any reference to the user’s role/title.

• Authentication.

It is the cybersecurity technique that is used to verify a user’s identity. There are three main factors of authentication:

• Passwords & Pins.

Passwords & pins are bits of private information and are only specific to the user who created it. This is the most common authentication and is the least secured too.

• Access Cards/Keys.

These cards ensure a high level of security by providing a two-factor authentication or a digital signature. An authorized user will have the access cards or key, using which he/she is permitted to get access to the system.

• Biometrics.

Biometrics is the most expensive and one of the most secured methods of authentication. It reads a user’s unique genetic attribute to confirm and identify a person. Some of the typical biometric scans include retina scan, Iris scan, Fingerprint, Facial scan, etc.

• Authorization.

The process of authorization comes after a person has gone through the identification and authentication process. Authorization controls the access level and the ability to change/edit specific data. A person without approval will never be able to change or edit particular data of the organization.

How Access Control works

Access control security is done through an individual’s identification, verifying whether the person is someone who he/she claims to be. The access level authorization is set according to the actions associated with the IP address.

Also, to provide access controls for authentication and authorization, the Directory services and protocols, including LDAP (Lightweight Directory Access Protocol) and SAML (Security Assertion Markup Language), are used. It also enables the connection between computer resources.

How to decrease the risk in Information Security Access Controls

• Never be relaxed when it comes to cybersecurity. Otherwise, you will put your company’s or business’s sensitive and financial data. Hence, you must be vigilant about cybersecurity. Make sure you and your employees the responsibility of ensuring cybersecurity.

• Whenever there is any update available, whether it’s your OS or the installed software, you must regularly install the updates. Keeping the software and your operating system up-to-date eliminates security loopholes and vulnerabilities.

• The employees in your organization must understand the importance of password management practices. The basic techniques include regularly changing/updating the password, implement a robust security access control. If you want to, you can always take the help of password management programs.

• Ensure your employee while they leave their physical device’s unattended, it should automatically lock to prevent unauthorized access.

Conclusion

I hope you got clear of what access control is and what role it plays in information security. Though there is a lot more to know about it, having a better overall understanding and working can give a brief overview of Access Control.

We intended to give you that brief overview through this post without you needing to get too technical.
