Digital certificates secure your business by protecting your devices and application. Therefore, it’s essential to manage them efficiently.
With digitalization, every business relies on data and software applications. Business owners need to secure them from hackers and cyberattacks. Digital certificates can secure your data and devices from unauthorized access.
If a site holder is not sure about the type of SSL certificate then, each site holder should look at number of domain and subdomains. For example, if there are multiple domains, you can go with multi-domain or in case of subdomains, you can go with a wildcard SSL certificate.
Day by day, organizations are becoming more connected with new technology and collaborative tools. So, cybersecurity is a vital part of a connected environment in the workplace.
Any issue in the management of digital certificates can hamper the reputation, cause a loss in productivity and profit. Now, read this article to learn how to manage your digital certificates more efficiently.
Ways to Manage Your Digital Certificates
Managing digital certificates can be difficult for many organizations. If that’s the case, consider certificate automation tools or software that can renew, manage, and secure your digital certificates. You can also adopt the following steps to manage your digital certificates on your own.
1. Create a Visible Certificate Inventory
You need to create a visible certificate inventory where you can store and maintain all the necessary details. The information includes certificate type, expiration date, certificate deployment, etc. You need to ensure that the certificates are regularly updated before expiration.
Otherwise, the entire chain of certificates will get corrupted. So, you need to maintain them in a visible environment where you can check the validity of each certificate and renew them at least 30 days before the expiration. After the renewal, you need to remove the expired certificates and ensure that they are inactive in the system.
2. Remove Unknown and Unused Certificates From the System
Unknown or unused certificates can cause harm to the system. So, remove them as soon as you find any unused or unknown certificates. You can avoid these problems by controlling the certificate purchase process.
Unused certificates are purchased to secure any device or application in the system but not deployed. On the other hand, unknown certificates are issued by rogue intermediate certificate authorities.
3. Don’t Use Weak Encryption Techniques
The security of your infrastructure depends on your encryption technique. Always use a strong cryptographic encryption method to avoid any security vulnerabilities. Some of the common encryption techniques are SHA1, SHA2, ECC, RSA, DSA, etc. It’s essential to avoid the techniques that have proven vulnerabilities.
Provide limited access to your keys within your organization. Limit the validity of self-signed certificates to 1 year to a maximum of 1.5 years. Because hackers get more time to hack the private keys if you don’t rotate them periodically.
4. Change Your Certificate Vendors Periodically
Another thing that you need to keep in mind is to change your certificate vendors. When you purchase all your certificates from a single vendor, it becomes vulnerable to cyber-attacks.
One of the best practices is to choose different vendors for different needs. Try to purchase your security certificates from a vendor that suits your business needs. Never share your certificates among different servers.
5. Configure Secure SSL Protocols
When you are configuring servers, try to use secure SSL protocols. You will find different versions of certificate protocols. Each protocol has different security features. Some of the common security protocols are SSL v3.0, TLS v1.0, TLS v1.1, TLS v1.2, and TLS v1.3.
There are a few vulnerabilities in SSL v3.0, so ensure that you use at least TLS v1.1. Usually, browsers always use the latest security protocol. However, sometimes it falls back to SSL v3.0 when a TLS negotiation is not available. You need to use secure protocols to protect your site from DDoS attacks.
6. Automate Your Certificate Lifecycle Management
It’s difficult to manually manage your digital certificates. You can use tools or software that can help you manage all your certificates automatically. Using automatic certificate lifecycle management can help you to renew, install, revoke, and maintains certificates securely and more efficiently.
The Bottom Line
Data security and encryption have become vital for every business today. It’s found that websites with HTTPs protocol rank better in search engines. So, it’s essential to adopt a standard certificate management system that will improve the security of your business. If you have any queries, please leave them in the comment section.
