The 2G Sunset Closed a Network. It Didn’t Close the Attack Surface Featured
The shutdown of the last major 2G Global System for Mobile Communications (GSM) network in the United States looks, at first glance, like the end of a technology era. The original iPhone has lost its last U.S. network. Decades-old cellular infrastructure is finally disappearing. Enterprises have one fewer legacy technology to worry about. But for organizations operating connected devices, the more important lesson has little to do with nostalgia or even with 2G itself.
When yesterday’s code becomes today’s threat
A striking new supply chain attack is sending shockwaves through the developer community: a worm-style campaign dubbed “Shai-Hulud” has compromised at least 187 npm packages, including the tinycolor package that has 2 million hits weekly, and spreading to other maintainers' packages. The malicious payload modifies package manifests, injects malicious files, repackages, and republishes — thereby infecting downstream projects.
Who’s responsible for digital trust?
Digital trust is the measure of confidence that we have in the digital products and services that we rely on every day. It’s built of the industry and technological standards, systems of operations and compliance, software that manages the delivery of that trust within an organisation and the efforts to extend trust across lifecycles, through software supply chains and everywhere else. As such, it is now an irrevocable business priority.
2024 Security Predictions
Originally published by DigiCert on November 8, 2023. As 2023 draws to a close, it’s time once again to look back on the past year’s security developments and make some bold predictions about the future of technology, identity and digital trust. Artificial intelligence (AI) was all over the news in 2023, and 81% of participants in a recent survey expressed concerns about the security risks associated with ChatGPT and generative AI.
How to fend off the manual certificate management tsunami
November 17, 2021 Brian Trzupek New data from DigiCert’s 2021 State of PKI Automation survey shows what a huge job certificate management can be. The headaches involved in managing such a complex web of certificates are quite understandable. They’re often the cause of security mishaps and sometimes operational paralysis. Certificates can be a double-edged sword. On one hand, they’re crucial to protecting modern and complex networks. On the other, they can pose an incredible burden to manage.
What SolarWinds Tells Us About Securing the Software Development Supply Chain
The recent SolarWinds attack highlights an Achilles heel for enterprises: software updates for critical enterprise applications. Digital signing of code is one solution, but organizations need to modernize their code signing processes to prioritize security and integrity and align with DevOps best practices, writes Brian Trzupek the Senior Vice President of Products at DigiCert in this thought leadership article.
Drowning in your own network?
The network is no longer as simple as it was. Where there once was a geographically defined perimeter, walled in with bricks and mortar and propped up by a handful of endpoints and servers - there now sits something much more complex. As Enterprise IT has evolved so too has the difficulty in managing it. For all of the benefits that technological advancement has wrought, each has created new problems.
Vous noyez-vous dans votre propre réseau ?
Le réseau n’est plus aussi simple qu’il l’était. Là où, autrefois, un périmètre physique était géographiquement défini (construit « de briques et de mortier ») et étayé par une poignée de terminaux et de serveurs, les choses sont aujourd’hui bien plus complexes. A mesure que l’informatique d’entreprise a évolué, sa gestion, de plus en plus difficile, en a fait de même. En dépit des avantages apportés, chaque avancée technologique a créé de nouveaux problèmes.
PKI Points the Way for Identity and Authentication in IoT
Modern enterprise networks are populated by both people and, increasingly, “things.” But securing the growing population of Internet of Things devices presents unique challenges. In this thought leadership article, Brian Trzupek, the Senior Vice President of Emerging Markets at DigiCert discusses what is needed for effective IoT security. We’ve seen the IoT come of age over just the past few years, and innovative use cases continue to build momentum.
How certificates enable trust even out of the office
Trust can be a tricky concept, especially when it comes to security. The age of network computing demands that we extend trust to lots of people - many of whom we don’t know. As remote working gains speed - we extend that trust not just to employees and users, but to their home devices, the wi-fi networks they use and the people they associate with. That’s at least partly why humans are so often called the weakest link in security.
Want Secure Remote Worker Access with VPN? These 5 Steps Get You Closer
Many remote employees must access a corporate private network from home to continue business as usual. Organizations are turning to virtual private networks (VPN) as never before to keep remote workers connected to critical information and tools. To protect sensitive data and network bandwidth, however, companies must secure and control that network access such as by incorporating digital certificates into their cybersecurity strategy.
Enabling Secure Remote Worker Access with VPN and PKI
The COVID-19 pandemic has dramatically transformed the workplace, with more workers than ever working remotely. And many of the changes are here to stay. According to a recent survey, more than 77 percent of HR executives expect the trend toward remote work to continue, even after the outbreak subsides. To safeguard sensitive company and end-user communications and data, it’s essential to keep remote workers connected while securing and controlling network access.
Securing digital transactions across an increasingly dynamic enterprise - ET CIO
By Brian Trzupek To safeguard the data that drives their key business processes, organizations need to restrict access to confidential information, classifying documents and other information, based on the user’s level of authentication. Today’s enterprise organizations are up against a wave of new challenges maintaining security and privacy. Conducting business electronically has long been the norm, but it can still leave information vulnerable.
