Do you have valuable data resources in your system? It is prudent to secure them with the right policies; otherwise, you will expose them to theft or manipulation.
Free access to your network is an invitation to cybercriminals. Access control checks who is allowed to access your system to prevent malicious activity. So what can you do to secure access to your system?
1. Connect access to user roles
No one should be able to access your system without proper identification. It’s like letting strangers into your home without asking for their ID. You must assign access roles and credentials to everyone who wants to access your system. It is on this premise that usernames and passwords exist.
Connecting access to user roles promotes accountability. If something goes wrong, you can trace it back to individual users. Each user must have a unique username and password. Otherwise, they could create multiple identities to manipulate the system.
2. Prioritize use cases
Don’t implement access control just for fun. You should focus on how your access control efforts serve and enhance your system security. Start by identifying the vulnerabilities in your network. Which areas pose a high security risk?
For example, if you suffered a data breach because a cybercriminal correctly guessed your password, you need to be more careful about generating stronger passwords. In this case, consider using passphrases and password generator tools to create hard-to-guess passwords.
3. Implement the principle of least privilege
A user who has unlimited access to your system can cause more damage than a user with limited access. As much as people need to perform certain tasks on your system, you should be wary of how much access they have.
For added security, grant users access only to areas that are relevant to them. Prevent them from exploring areas they have nothing to do with. Although this may seem strict, it will help you check user activities on your system and limit the damage if their account is compromised. This is called the Principle of Least Privilege (POLP).
If someone needs access to areas that are not in their coverage area, they must request access from you. If you choose to grant such a request, keep an eye on their activities for any foul play and cancel it as soon as possible.
4. Use Many Layers of Security
Visualize the worst-case scenarios for securing your system, so you can deal with them. This involves taking a proactive approach to cybersecurity instead of a reactive one. What happens if cyber attackers bypass the username and password single sign-on you have installed?
Creating additional layers of security with tools like multi-factor authentication strengthens your access control. Someone must then be able to bypass all the steps to successfully break into your system.
5. Regularly review and improve access control
There is a tendency to overlook existing access control systems, especially when you are busy with other activities. But change is constant. The people accessing your system today may not always be around you. You must end users’ access to your system when they are no longer working with you. If you don’t, they can take advantage of the situation and compromise your data.
If you need to hire contractors and grant them access to your system to perform their tasks, be sure to remove their access once they have completed their work.
You may forget to revoke access from users you no longer need. To prevent this from happening, have a policy of periodically reviewing your access control.
Securing your digital assets with access control
There’s a reason people put in place tight security at the entrance to their physical buildings: they need to stop intruders and attackers at the door, so they don’t enter the building where they are. their relatives and property.
Access control is an essential step in cybersecurity because it secures the point of entry to systems. It is better to implement access control best practices to ward off cyber threats than to deal with a full-scale attack.
