Computer Security: A final spurt for improved networking
2026 will bring improved and more granular network filtering to the Technical Network (TN) and, later, between the Campus and data centre networks, introducing a pair of redundant firewalls for each

Computer Security: A final dash to protect your account
We already discussed mandatory requirements for IT service managers in a past issue of the Bulletin. This time we present upcoming changes to passwords and improvements to two-factor authentication

Computer Security: A final marathon for service managers
The past two years have brought a lot of new computer-security deployments at CERN: 2-factor authentication, new spam filtering, email quarantining, anti-spoofing protection, 2FA protection for LXPLUS and the CERN Windows Terminal Servers, among others

Celebrating two decades of global scientific computing
Developed to handle the vast amounts of data of the LHC experiments, the Worldwide LHC Computing Grid has significantly marked the landscape of distributed computing

Computer Security: Your ticket to improvement
The past two years have brought a lot of new computer-security deployments at CERN. Some of these were not the most user-friendly for the CERN community, as this is not in the inherent nature of “security”, but we tried our best

Computer Security: Password evolutions
Following the successful deployment of two-factor authentication (2FA) to more than 42 000 CERN accounts, one final step to ensure full compliance with the recommendations of the 2023 audit on CERN’s cybersecurity remains

When failure is good news
The software managing CERN’s compute workload has handled a massive stress test, far beyond normal operating conditions, designed to simulate the needs of the future

Computer Security: 20 years of securing controls (or trying to): mitigations
We’ve seen in the past two Bulletins that control system cybersecurity is the black sheep of IT, a hard-to-change tanker’s course. Still, with significant daily damage of 250 000 USD for ALMA, the costs of falling to a cyberattack can no longer be ignored

Computer Security: 20 years of securing controls (or trying to): black swans and convergence
While eagerly expected by experts, the first dominant incident on control systems reported by the media was the Stuxnet attack of 2010 against the Iranian nuclear programme allegedly conducted by some secret services
