Zero Trust Network Access (ZTNA): Reducing Lateral Movement
/by Wayne Lloyd, Federal CTO, RedSealIn football, scoring a touchdown means moving the ball down the field. In most cases, forward motion starts the drive to the other team’s end zone. For example, the quarterback might throw to a receiver or handoff to a running back. Network attacks often follow a similar pattern: Malicious actors go straight for their intended target by evaluating the digital field of play and picking the route most likely to succeed.
In both cases, however, there’s another option: Lateral movement. Instead of heading directly for the goal, attackers move laterally to throw defenders off guard. In football, any player with the ball can pass parallel or back down the field to another player. In lateral cyberattacks, malicious actors gain access to systems on the periphery of business networks and then move “sideways” across software and services until they reach their target.
The House Always Wins? Top Cybersecurity Issues Facing the Casino and Gaming Industry
/by Jane Paolucci, CMOHead into a casino, and you should know what you’re getting into — even if you see some success at the beginning of the night, the house always wins. It’s a truism often repeated and rarely questioned but when it comes to cybersecurity, many casino and gaming organizations aren’t coming out ahead. In this post, we’ll dive into what sets this industry apart, tackle the top cybersecurity issues facing casino and gaming companies, and offer a solid bet to help build better security infrastructure.
HIMSS Roundup: What’s Worrying Healthcare Organizations?
/by Jane Paolucci, CMOThe HIMSS 22 Global Health Conference and Exhibition took aim at some of the biggest opportunities and challenges facing healthcare organizations this year. While businesses are taking their own paths to post-pandemic operations, both the content of sessions and conversations with attendees revealed three common sources of concern: compliance operations, the Internet of Healthcare Things (IoHT), and patient access portals. Conversations with healthcare and IT professionals at HIMSS 22, made it clear that what worries organizations is changing and to ensure effective security, responses must evolve as well.
Zero Trust: Back to Basics
/by Wayne Lloyd, Federal CTO, RedSealThe Executive Order on Improving the Nation’s Cybersecurity in 2021 requires agencies to move towards zero trust in a meaningful way as part of modernizing infrastructure. Yet, federal agencies typically find it challenging to implement zero trust. While fine in theory, the challenge often lies in the legacy systems and on-premises networks that exist with tendrils reaching into multiple locations, including many which are unknown. Identity management and authentication tools are an important part of network security, but before you can truly implement zero trust, you need an understanding of your entire infrastructure. Zero trust isn’t just about identity. It’s also about connectivity.
Zero Trust: Shift Back to Need to Know
/by Wayne Lloyd, Federal CTO, RedSealCyberattacks on government agencies are unrelenting. Attacks on government, military, and contractors rose by more than 47% in 2021 and can continue to climb. Today’s cybercriminals, threat actors, and state-sponsored hackers have become more sophisticated and continue to target government data and resources. For governmental agencies, hardening security requires a return to “need to know” using zero trust security protocols.
Ransomware Realities: Exploring the Risks to Hybrid Cloud Solutions
/by Jane Paolucci, CMOHybrid cloud frameworks offer a way for companies to combine the scalability of public clouds with the security and control of their private counterparts, and pandemic pressures have accelerated hybrid adoption. Along with increased uptake, is a commensurate uptick in ransomware risks. With attackers leveraging the distributed nature of remote work environments to expand their attack impact, organizations must recognize potential challenges and develop frameworks to mitigate ransomware threats effectively.
Keep it Separate, Keep it Safe: How to Implement and Validate Cloud Network Segmentation
/by Jane Paolucci, CMOThe distributed nature of cloud computing makes it a must-have for business, thanks to on-demand resource availability, network connectivity, and compute scalability. But the cloud also introduces unique security challenges. Cloud network segmentation offers a way for companies to reduce the risk of cloud threats. By dividing larger networks into smaller subnets — each of which can be managed individually — businesses can boost protection without sacrificing performance.
Do You Need a More Intelligent and Secure Network?
/by Jane Paolucci, CMOEffective security tools are now table stakes for organizations to ensure they meet evolving legislative standards around due diligence and data control. But these straightforward security measures aren’t enough to address the evolving nature of information technology (IT) environments — from rapid cloud adoption to mobile-first environments to the update of edge computing. The sheer volume and variety of corporate IT environments create organizations’ ever-changing challenges.
On the Internet We’re All in a War Zone: Why it’s Time to Prepare for the Worst
/by Jane Paolucci, CMOSadly, once again we find ourselves watching war as it unfolds. The truth is that, by accident or design, we’re all in a war zone online, because online conflict does not respect country boundaries or even physical distance. Western targets must prepare accordingly, by understanding their attack surface in granular detail, and probing for weaknesses that could be exploited by adversaries in the days, weeks and months to come. Resilience is the name of the game here, and that will only come about by plugging the highest risk gaps now across cloud and on-premises infrastructure.
How Security Vulnerabilities Expose Thousands of Cloud Users to Attacks
/by Jane Paolucci, CMOCloud computing has revolutionized data storage and access. It’s led the charge for digital transformation and allowed the increased adoption of remote work. At the same time, however, cloud computing has also increased security risks. As networks have grown and cloud resources have become more entrenched in workflow, cloud computing has created larger potential attack surfaces. To safeguard their mission-critical data and operations, organizations need to know chief cloud cyber risks and have to combat them.
