In 2023, companies lost about $4.45 million on average because of data breaches. As cyber threats advance, securing endpoints is more important than ever. An advanced Host-based Intrusion Detection System (HIDS) provides a sturdy remedy to improve endpoint security . By monitoring and examining system responses and device status, HIDS identifies and tackles nefarious behaviors that are often...

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...

On an ordinary day, you're casually surfing the web and downloading some PDF files. The document icons seem pretty legitimate, so you click without a second thought. But, to your surprise, nothing happens. A closer look reveals that what you believed to be a harmless PDF was, in fact, an executable file. Panic sets in as your settings lock up, and even accessing the task manager becomes impossible...

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...

The demand for innovative threat detection and intelligence approaches is more pressing than ever. One such paradigm-shifting technology gaining prominence is Federated Learning (FL). This emerging concept harnesses the power of collaborative intelligence, allowing disparate entities to pool their insights without compromising sensitive data. A report by Apple suggests that the number of data...

What Is a Host-Based Intrusion Detection System (HIDS)? A host-based intrusion detection system, or HIDS , is a network application that monitors suspicious and malicious behavior, both internally and externally. The HIDS’ job is to flag any unusual patterns of behavior that could signify a breach. By bringing this activity to the team’s attention, the HIDS enables in-house staff to investigate...

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...

Earlier this year, the SEC proposed a new set of rules on cybersecurity governance , which would require public companies to make appropriate disclosures of cyber risks and management procedures. Although the amendments target the financial sector, it is one more evidence of the fact that cybersecurity is no longer a backburner component of business operations. It is a critical factor that can...
