The number of endpoints in an organization often exceeds the number of employees. Managing these often disparate entities is more than a full-time job. Moreover, keeping them secure is equally difficult, yet securing all of your endpoints against cyber threats has become paramount for organizations worldwide. A common oversight that undermines these security efforts is the misconception about data...

In today's digital landscape, it is important for organizations to depend upon the tools they use for cybersecurity. Large businesses can employ many security solutions, practices, and policies that must combine to create a robust and layered security strategy. While many of these tools are important and necessary, organizations often don't use them to their full potential. With any security tool...

I’ll start this one with an apology – I’ve been watching a lot of the TV show The Bear (which I’d highly recommend!) and thus been thinking a lot about kitchen processes and the challenges of making everything come together nicely (both in life and in a recipe). If you are unfamiliar with the show, it is a comedy-drama about a chef who manages his deceased brother’s sandwich shop. When I see...

Thanks to the burgeoning supply chain, a host of IoT and work-from-home devices, and an expanding cloud presence, organizations are constantly ingesting new hardware into their IT environments. With each new line of code comes a fresh chance for a hidden vulnerability. With each unfound weakness, attackers gain one more opportunity to gain a foothold in the organization and compromise sensitive...

Any time the television news presents a story about cybersecurity, there is always a video of a large data center with thousands of blinking lights. Even most cybersecurity blogs will include an image of many lights on the front panels of servers, routers, and other hardware. However, most people don’t notice that the lights are usually green or some shade of blue. Rarely are those lights yellow...

Using security tools to monitor activities on IP based endpoints and the resulting changes that occur pose one of the most formidable challenges to security and regulatory compliance efforts, thanks to its potential to disrupt established security measures and protocols. Compliance frameworks, such as PCI DSS and NIST 800-53/SI-7, require organizations in every sector to maintain a consistent and...

Energy efficiency and availability is a major concern for all countries and governments. The electric grid is a vital sector, and any malfunctions will create ripple effects on any nation’s economy. As the grid is heavily dependent on cyber-enabled technologies and a vast chain of suppliers, contractors, and partners, the ability to safeguard the availability and reliability of the grid is crucial...

Distributed Denial of Service (DDoS) attacks occur when adversaries overwhelm a connected target’s resources, aiming to make it unavailable. Learning the best strategies to protect from DDoS attacks is critical to energy grid cybersecurity. A well-planned DDoS attack on the grid could halt essential services, cause substantial disruptions to households and businesses, and prove incredibly costly...

Have you ever considered that even before you enjoy the first sip of your favorite morning beverage, you have probably interacted with at least half of the 16 critical infrastructure sectors that keep a nation running? In one way or another, the simple act of brewing a cup of tea would probably not be possible without interacting with water, energy, manufacturing, food and agriculture, waste...

2023 saw two concerning attacks on public water systems, highlighting the fragility and risk to utility systems. In Pennsylvania, malicious hackers breached the Municipal Water Authority of Aliquippa system the night after Thanksgiving. The criminals were making a political statement: the technology used to manage water pressure was developed by Israel, and the criminals used this opportunity to...

US federal agencies have teamed up to release a cybersecurity best practice guidance for the water and wastewater sector (WWS). The Cybersecurity and Infrastructure Security Agency (CISA), United States Environmental Protection Agency (EPA), and Federal Bureau of Investigation (FBI) have published the guide in an attempt to promote cybersecurity resilience and improve incident response in the WWS...

Imagine you’re on the tail end of installing a 100-line script. It’s five o’clock, and you’re ready to head out early for once. You run the startup script on a new server, and then – the fated error message. Something isn’t working, and only after painstakingly reviewing 67 lines of code do you realize you had the IP address wrong. This could have been prevented. File Integrity Monitoring (FIM)...

At Tripwire's recent Energy and NERC Compliance Working Group, we had the opportunity to speak with the Manager of Gas Measurement, Controls, & Cybersecurity at a large energy company. More specifically, we focused on SCADA and field assets of gas Operational Technology. The experience at the management level of such an organization provided a wealth of knowledge for the attendees. SCADA...

The shifting sands of IT make the adage "you never know it all" ever more true as time goes by. I recall days when it felt like you could click through every major directory of Yahoo and know a little something about everything. I was a young man with a voracious reading appetite and an active imagination – both of which were thoroughly outpaced by the growth of the internet and my own developing...

In the digital world, where countless users communicate, share data, and engage in diverse activities, determining the origin and actions behind these interactions can be quite challenging. This is where non-repudiation steps in. Coupling other security factors, such as delivery proof, identity verification, and a digital signature, creates non-repudiation. This guarantees that the parties...

Frankly stated, operational resilience is your ability to climb the mountain, no matter the weather. Businesses now need more than a good security structure to weather the storms of AI-driven threats, APTs, cloud-based risks, and hyper-distributed environments. And more importantly, operational resilience in 2024 requires a paradigm shift. Attackers aren’t out there doing the bare minimum . As the...

In the vast and ever-evolving universe of information technology, there's one constant: change (that and cliches about constants!). Servers, systems, and software – they all get updated and modified. But, have you ever stopped to consider how even tiny differences between these digital entities can sometimes lead to unexpected challenges? In the world of Tripwire, we like to call this phenomenon...

More decision-makers are investing in grid modernization efforts, knowing that doing so is necessary for keeping pace with modern demands. For example, smart grid fault-detection sensors could warn utility company providers of problems in real time, preventing costly and inconvenient outages. Technologies like the Internet of Things (IoT) can also improve stability. An IoT grid-monitoring approach...

Attacks against industrial control systems (ICS) are on the rise. Cyberattacks are more prevalent, creative and faster than ever. So, understanding attackers’ tactics is crucial. The IBM Security X-Force Threat Intelligence Index 2023 highlights that backdoor deployments enabling remote access to ICS systems were the most common type of attacker action in 2022. The positive news is that 67% of...

Electric grids are part of every nation’s critical infrastructure. Every societal activity and business depends on reliable and safe electricity distribution. The US electric grid is a huge network of powerlines, distribution hubs, and renewable and non-renewable energy generators that is increasingly exposed to cyber-physical risks due to the accelerated reliance on cyber-enabled systems and IoT...
