Access control is crucial to a business’s cyber security. Organisations must always ensure that users are who they say they are and have the authorisation to access certain network resources or enter restricted regions to be secure.

Access control not only serves to safeguard assets but may also aid in tracing actions and determining the reason for a breach.

In this article, we will analyse the importance of access control in cyber security.

Understanding Access Control

Physical and logical access controls are the two types of access controls. Physical controls restrict access to buildings, workstations, and IT infrastructure, whereas logical controls restrict access to important cyber assets. 

Both are critical for cyber security and begin with the assumption that people, devices, and other entities requesting access are unknown until the system can validate them.

For this to happen, they must have a distinct and well-known ID, such as a username, email address, or MAC address, which identifies them when they seek to access files.

A cyber security risk assessment immediately marks weak and insufficient safeguards as they are a tragedy waiting to happen. Here are some reasons you should restrict user permissions:

Preventing Accidental Data Exposure

Do you need someone from accounting or any specific department to have user access to all of your data and systems? They most likely just require access to specified regions or functions to do their job. An IT administrator, on the other hand, would want more rights and user permissions, including extensive access to your network and IT infrastructure.

Extraneous user rights are unnecessary for most work departments, and they pose a possible cybersecurity risk if they are unaware of—or fail to follow—good cybersecurity practices. 

It does not necessarily imply that someone has malevolent intent; they may be unaware of what they should (or should not) do with this access. Furthermore, these sorts of activities might result in the unintentional disclosure of corporate or client data.

Avoiding Privilege Misuse and Abuse

Employee or contractor negligence is the most significant cause of data breaches globally. This can result in privilege abuse. Intentional misuse of user accounts can result in the theft, leakage, or loss of data and intellectual property, as well as a slew of other problems.

Reducing the Risk of Hackers Compromising Login Credentials

Restriction of user rights can assist in reducing the harm done when an employee’s or contractor’s account is hacked. If the user access to the account is unfettered, a malicious user might have a field day with access to your whole system. This will cost you money and customer faith in your organisation and brand.


Cyber security is a significant issue for any business and becoming more of a concern as the digital world grows. To best protect your organisation from cyber threats, hiring cyber security consulting services and limiting users’ access to your network and information is essential.

Access control is integral in cyber security and should be considered when formulating a cyber security policy. It helps to control who has access to what cyber assets and provides an excellent way to trace the actions of a cyber attacker if needed.
