Unexpected Interruption: Government Websites Temporarily Unreachable Due to Certificate Issues

Alarm Bells Raised for Government Websites

Recently, concern arose when it became apparent that the security certificates of various government websites, including those of Logius and several municipalities, might no longer be valid. This led to worries about the accessibility and security of these crucial online services. The issue seemed to stem from the certificate authority CertSIGN in Romania.

They manage the issuance and verification of digital certificates needed to secure websites with HTTPS.

How Does a TLS Certificate Work?

A TLS (Transport Layer Security) certificate is essential for online security. It ensures that the connection between your browser and the website you are visiting is encrypted. This means sensitive information, such as passwords or payment details, is protected from prying eyes.

You can recognize a secure connection by the 'padlock' icon in your browser's address bar and the use of 'https://' instead of 'http://'. Certificates are issued by trusted entities, known as 'Certificate Authorities' (CAs), like CertSIGN.

The Role of CertSIGN and the Mistake Made

CertSIGN is a party that issues these security certificates. When a certificate is revoked, it is registered in a special list, the Certificate Revocation List (CRL). The CRL acts as a 'stop sign' for browsers and other systems; it indicates that a certificate can no longer be trusted.

In this specific case, CertSIGN's CRL indicated that the certificates for several government websites had been revoked. This could be a direct cause of the sudden unreachability of these websites, as browsers block connections to such secured sites for security reasons.

The Impact of an 'Expired' Certificate

An expired or revoked certificate will cause visitors to see a warning when they attempt to access the website. This warning can deter visitors from proceeding, leading to a poor user experience and potentially a loss of trust. For organizations that rely on their website for service delivery, this can have significant consequences, such as lost customers or frustration among citizens.

The Technical Cause

It appears there was a malfunction in how CertSIGN shared or maintained information about certificate validity. This could lead to a situation where valid certificates were incorrectly marked as 'invalid'. Normally, flawless communication between the certificate issuer and those who verify the certificates ensures smooth online communication.

An interruption in this process can, as has happened now, have major consequences.

What Does This Mean for Your SME?

This situation, although it occurred with government websites, serves as an important reminder for every business, large or small. Your SME also depends on reliable and secure online communication. The impact of a similar problem on your own website or online services could be substantial.

Can you afford for your webshop to suddenly become inaccessible to customers? Or for your customers to receive warnings about the security of your website?

Important considerations for SMEs:

• Check your own certificates: Ensure that the TLS certificates for your own website and any other online services, such as webshops or customer portals, are renewed in time and remain valid. Regularly check their status.
• Choose a trustworthy certificate issuer: Partner with reputable parties for the issuance of your certificates. While even the best can make a mistake, choosing an established name reduces the risk.
• Do you have a Plan B?: Consider what you would do if your website suddenly became unreachable. What are the communication channels to inform your customers about the issues and when they can expect it to be back online?
• Diversify where possible: If your business is heavily reliant on a single online platform or service, consider spreading critical functions across multiple systems, if practically feasible.
• Be alert to warnings: Train your employees to recognize the signs of insecure connections and how to respond appropriately. This fosters a culture of digital vigilance.

Although the direct cause lay with an external party, this incident demonstrates how interconnected the digital world is. A problem 'behind the scenes' can have direct visible consequences for the end-user, and thus for your customers. By acting proactively and managing your own digital infrastructure, you can prevent common problems or minimize their impact.

Conclusion

The incident involving the government websites serves as a valuable lesson for the entire business community. It highlights the importance of reliable digital certificates and the potential impact of errors by certificate issuers. For SMEs, it is crucial to remain vigilant, check their own digital security, and take proactive measures.

By properly managing your TLS certificates and having a plan for unforeseen circumstances, you can ensure the continuity of your online services and maintain customer trust in an increasingly digital world.
