Ransomware is nothing new. But the tactics, techniques and procedures (TTPs) leveraged by threat actors have reached new levels of sophistication over the last few years. And with that growth has come an increased difficulty in protecting networks against costly attacks such as the recent DarkSide one on the Colonial Pipeline.
Cybersecurity is not a one-and-done proposition. Deterring cybersecurity threats and remediating incidents is a complex and never-ending responsibility. Malicious state actors, cybercriminals and corporate espionage are just a few sources of cyberattacks. Each one uses dozens of ever-evolving techniques to overcome security safeguards.
Access to clinical applications and medical information in a digital healthcare environment is vital. Yet, careful consideration must be made to ensure data and systems are protected against unintended or malicious activities. Securing infrastructure and applications is essential and security professionals must not forget about the devices that facilitate, segregate and protect the network.
As 5G technology continues to be rolled out worldwide—providing latency of a mere 1 millisecond—it is critical that information security professionals become familiar with 5G system architecture and security architecture, as well as the risks that come with implementing new cellular technologies. ISACA’s new white paper, 5G Security: Addressing Risk and Threats of Mobile Network Technologies, explores these topics, and compares 5G technology with 4G and previous generation cellular technologies.
It’s easy to see how network tool sprawl gets started. The needs and challenges facing security and networking groups are immense. Network speeds have steadily increased, and there are always new demands and uses. Network conditions and requirements change weekly, if not daily. Security threats increase in number and approach. At the same time, technological advancement rapidly brings new solutions to the market that are beneficial in addressing networking and security needs.
To help you and your organization plan and implement an improved cyber hygiene program, we now present a framework for full IoT device defensibility in real world deployments at scale. This framework represents current state-of-the-art best practices for protecting IoT devices, and can form the backbone of your assessment, evaluation, and improvement plans. Follow the steps below to strengthen your network defenses.
The time it takes to get engineers onsite (52% in the US and 42% globally), inadequate network monitoring (41% in the US and 36% globally) and a lack of in-house skill (40% in both the US and globally) are among the biggest challenges organizations face in resolving a network outage quickly, according to a recent study commissioned by Opengear, a Digi International company.
Multiple intelligence agencies are releasing a joint cybersecurity advisory on technical approaches to incident response and best practices to remediating malicious cyber activity.
Zero Trust model creator John Kindervag puts it like this: “The point of Zero Trust is not to make networks, clouds, or endpoints more trusted; it's to eliminate the concept of trust from digital systems altogether.” He came up with the model in 2010, at a time when many businesses were just beginning to put foundational cybersecurity controls in place and over-relied on the assumed security inside their enterprise-owned network boundaries.
