Posted on : June 3, 2025 By Tech World Times Technology  Rate this post This article walks you through five practical steps to implement network segmentation effectively, backed by real-world use cases that showcase its value in different industries. Networks are constantly expanding across offices, cloud services, remote users, and connected devices. With so many moving parts, security gaps can easily form. Once attackers breach a weak point, they often move freely across the network, targeting critical systems and sensitive data. That’s where network segmentation comes in. It’s a practical approach to divide your network into smaller, manageable zones to control access, limit exposure, and isolate threats before they spread. But simply deploying VLANs or access rules isn’t enough. True segmentation needs planning, alignment with your business, and the right mix of technology. Step 1: Assess and Map Your Current Network Start by figuring out what’s on your network and how it communicates. Inventory Devices and Applications: List all system servers, user machines, IoT devices, cloud assets. Map Data Flows: Understand how applications and services interact. Which systems talk to each other? What ports and protocols are used? Identify Critical Assets: Highlight the systems that handle sensitive data, such as payment processing, health records, or intellectual property. Tip: Network discovery tools or NAC solutions can automate asset inventory and reveal communication paths you might miss. Step 2: Define Segmentation Goals and Policies Once you understand your environment, it’s time to set your objectives. Security Objectives: Do you want to reduce lateral movement, isolate sensitive systems, or meet a compliance mandate? Business Alignment: Segment by business unit, sensitivity of data, or risk profile-whatever makes the most operational sense. Compliance Requirements: PCI DSS, HIPAA, and other standards often require network segmentation. Example: A healthcare provider might create separate zones for patient records, lab equipment, guest Wi-Fi, and billing systems. Step 3: Choose the Right Segmentation Method Segmentation can be done in several ways. The right approach depends on your infrastructure goals and types: a. Physical Segmentation Use separate routers, switches, and cables. This offers strong isolation but can be costly and harder to scale. b. Logical Segmentation (VLANs/Subnets) Group devices into virtual segments based on function or department. It’s efficient and easier to manage in most environments. c. Micro segmentation Control access at the workload or application level using software-defined policies. Ideal for cloud or virtualized environments where you need granular control. d. Cloud Segmentation In the cloud, segmentation happens using security groups, VPCs, and IAM roles to isolate workloads and define access rules. Use a combination- VLANs for broader segmentation and micro segmentation for finer control where it matters. Step 4: Implement Controls and Monitor Traffic Time to put those policies into action. Firewalls and ACLs: Use access controls to manage what can move between zones. Block anything that isn’t explicitly allowed. Zero Trust Principles: Never assume trust between segments. Always validate identity and permissions. Monitoring and Alerts: Use your SIEM, flow monitoring tools, or NDR platform to watch for unusual traffic or policy violations. Common Pitfall: Avoid “allow all” rules between segments, it defeats the purpose. Step 5: Test, Validate, and Fine-Tune Even a well-designed segmentation plan can have gaps. Regular validation helps ensure it works as expected. Penetration Testing: Simulate attacks to check if boundaries hold. Review Policies: Business needs to change your segmentation strategy too. Performance Monitoring: Make sure segmentation doesn’t impact legitimate operations or application performance. Automation tools can help simplify this process and ensure consistency. Real-World Use Cases of Network Segmentation 1. Healthcare – Protecting Patient Data and Devices Hospitals use segmentation to keep medical devices, patient records, and visitor Wi-Fi on separate zones. This prevents an infected guest device from interfering with critical systems. Result: Reduced attack surface and HIPAA compliance. 2. Manufacturing – Isolating Industrial Systems Production environments often have fragile legacy systems. Segmenting OT (Operational Technology) from IT ensures ransomware or malware doesn’t disrupt manufacturing lines. Result: More uptime and fewer operational risks. 3. Finance – Securing Payment Systems Banks and payment providers use segmentation to isolate cardholder data environments (CDE) from the rest of the corporate network. This helps meet PCI DSS and keeps sensitive data protected. Result: Easier audits and stronger data security. 4. Education – Managing High-Volume BYOD Traffic Universities segment student Wi-Fi, research labs, and administrative systems. This keeps a vulnerable student device from spreading malware to faculty or internal systems. Result: Safer environment for open access campuses. 5. Cloud – Segmenting Apps and Microservices In the cloud, developers use security groups, VPCs, and IAM roles to isolate applications and limit who can access what. This reduces risk if one workload is compromised. Result: Controlled access and better cloud hygiene. Common Challenges Legacy Tech: Older devices may not support modern segmentation. Lack of Visibility: Hard to secure what you don’t know exists. Operational Hiccups: Poorly planned segmentation can block business workflows. Policy Complexity: Keeping access rules up to date across dynamic environments takes effort. Best Practices Start with High-Risk Areas: Prioritize zones handling sensitive data or vulnerable systems. Keep Documentation Updated: Maintain clear diagrams and policy records. Align Teams: Get buy-in from IT, security, and business units. Automate Where You Can: Especially for monitoring and policy enforcement. Review Regularly: Networks evolve- so should your segmentation. Final Thoughts Segmentation isn’t about creating walls it’s about building smart pathways. Done right, it helps you take control of your network, reduce risk, and respond faster when something goes wrong. It’s a foundational layer of cybersecurity that pays off in resilience, compliance, and peace of mind. About the Author: Prajwal Gowda is a cybersecurity expert with 10+ years of experience.

If you’ve ever wondered whether the food on your plate could shape your brain’s future, the science is starting to say: yes, it might. While healthy eating has long been linked to better brain health, new research is getting more specific about which diets help, and when you should start following them.At this year’s annual Nutrition conference in Orlando, Florida, researchers presented findings that add weight to the growing link between diet and dementia. According to a news release, study author Song-Yi Park of the University of Hawaii at Manoa said, “Our study findings confirm that healthy dietary patterns in mid to late life and their improvement over time may prevent Alzheimer’s and related dementias. This suggests that it is never too late to adopt a healthy diet to prevent dementia.”The research focused on nearly 93,000 U.S. adults from the long-running Multiethnic Cohort Study. Participants were between 45 years and 75 years old when they entered the study in the 1990s. Over time, more than 21,000 developed Alzheimer’s disease or related dementias — but those who closely followed a specific eating plan, the MIND diet, were significantly less likely to be among them.Combining the Mediterranean Diet and DASH DietThe MIND diet (short for Mediterranean-DASH Intervention for Neurodegenerative Delay) blends the best elements of two established eating plans: the Mediterranean diet and the DASH diet.The Mediterranean diet is inspired by the traditional cuisines of countries like Greece, Italy, and Spain. It focuses on plant-based foods (fruits, vegetables, legumes, nuts, seeds, and whole grains), healthy fats like olive oil, and moderate amounts of fish, poultry, and dairy, with red meat eaten sparingly. It’s been linked to a lower risk of heart disease and is also environmentally friendly.The DASH diet, originally designed to lower blood pressure, shares many similarities but puts extra emphasis on limiting sodium and increasing intake of nutrients like potassium, magnesium, and calcium. It includes low-fat dairy and lean protein sources and doesn’t rely on any hard-to-find foods.The MIND diet specifically promotes brain-healthy foods like leafy greens, berries, nuts, and olive oil, combining benefits of both approaches with a focus on protecting cognitive health.Read More: Is the Mediterranean Diet Healthy?The MIND Diet Over TimeAccording to Park and her team, people who scored highest in MIND diet adherence at the study’s start had a 9 percent lower risk of developing dementia. That number was even higher with around 13 percent for African American, Latino, and White participants. Looking at those who improved their adherence to the MIND diet over time, showed a 25 percent reduction in dementia risk compared to those whose dietary habits declined, which was consistent no matter the age or racial background.“We found that the protective relationship between a healthy diet and dementia was more pronounced among African Americans, Latinos, and Whites, while it was not as apparent among Asian Americans and showed a weaker trend in Native Hawaiians,” Park said in the press release. “A tailored approach may be needed when evaluating different subpopulations’ diet quality.”Interestingly, Asian Americans also tend to have lower dementia rates overall, which researchers believe could mean other cultural eating patterns might offer similar protection than the MIND diet for that group.The Best Time to Start Is NowOne of the most encouraging findings was that starting late still helped. Participants who began following the MIND diet more closely over a 10-year period, regardless of how old they were when they began, saw benefits. This suggests that even if you didn’t grow up eating brain-boosting foods, it’s not too late to change course.It’s worth noting that the study is observational, so, by itself, it can’t prove this specific diet causes better brain health. Study author Park notes that the next step is conducting interventional studies to verify these promising results.Still, the evidence is mounting. Whether you're 45 or 75, choosing greens over greasy snacks could make a real difference when it comes to aging with or without dementia.This article is not offering medical advice and should be used for informational purposes only.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

RoboCop: Rogue City – Unfinished Business preview: ‘We created something bigger than we expected’ Adam Starkey Published June 3, 2025 9:00am Stay out of trouble (Nacon) GameCentral goes hands-on with the standalone expansion of RoboCop: Rogue City, which dials up the action and gory splatter of 2023’s surprise hit. For a franchise that has arguably done nothing of worth since the early 90s, the future of RoboCop is looking surprisingly bright. Following Amazon’s acquisition of MGM, a new TV show is currently in the works, with rumbles of a new film as well. Whether this leads to a major rejuvenation for everyone’s favourite cyborg law enforcer remains to be seen, but the original source of any RoboCop redemption arc has to start with 2023’s RoboCop: Rogue City.  Developed by Polish studio Teyon, RoboCop: Rogue City was the kind of unexpected surprise you rarely get from licensed games. It recaptured the original’s wit and 80s aesthetic, but also found a way to deliver the fantasy of playing as the half-human cyborg without streamlining any of the character’s personality. The bloody action was built around his hulking, slow movement, dry one-liners were in abundance, and missions weren’t always reduced to mowing down thugs in corridors – you also handed people parking tickets, settled trivial civilian disputes, and, in one wonderfully mundane side mission, did the rounds in the office for a get well card.  The game became publisher Nacon’s ‘best ever launch’ with 435,000 players within two weeks. Now, a year and a half later, developer Teyon is back with a standalone expansion. Marketing around Unfinished Business has purposefully dodged the term *DLC*, but as explained by the studio’s communications manager, Dawid Biegun, it started out as exactly that.  ‘When we released RoboCop: Rogue City, we were thinking about, this story has many things [we can] do in the future,’ says Biegun. ‘We had many paths we could choose. So we basically started slowly developing some new storyline. The game was planned to be DLC but it grew out of control. It was a really rare situation where we created something bigger than we expected, so it became a standalone expansion from then.’ Unlike Rogue City, this expansion, which we’re told spans around eight hours on average, is centred around one location in the OmniTower. Like most things in the RoboCop realm created by OCP, this promised idyllic housing complex quickly goes south when a band of mercenaries assume control. To restore order, and after a creepy opening where an attack on the Detroit police station leaves several officers frozen solid, RoboCop is assigned to the case.  RoboCop has new moves at his disposal (Nacon) Unfinished Business wastes little time in throwing you into the action, and quickly amps up the chaos. For anyone who has played Rogue City, all the original tenets of the combat are here, albeit with a slight increase in difficulty. You’ll be looking for explosive cans to blast, illuminated panels to ricochet bullets off walls, and all the while trying not to expose yourself to too much gunfire. The combat purposefully doesn’t have the slick speed of Call Of Duty, but it is still aggressively punchy, with headshots resulting in satisfyingly bloody splatters and RoboCop’s famed Auto-9 machine pistol still having the kickback of a pocket pneumatic drill.  From the get-go, Unfinished Business pushes back in a way Rogue City never did. New enemies equipped with riot shields are a real nuisance if you don’t utilise the ricochet panels, while the ability to slow down time is a much bigger crutch to chip down the enemy numbers from a distance. Health pick-ups felt in shorter supply too, even on the normal difficulty, to the point where we barely scraped through several encounters.  While it’s unclear if this applies to the whole game, Unfinished Business feels like a gnarlier experience, when compared to the original. RoboCop has some new context sensitive finishing moves, like throwing enemy heads into concrete walls or vending machines, which is a satisfying addition to the melee arsenal. There’s greater enemy variety too, between fierce minigun heavyweights and flying drones, along with some neat action set pieces. In one standout, we had to operate a walkway bridge to deactivate a giant turret at the end of a room, dashing between cover as it rains down bullets and destroys the surrounding environment. Anyone who has played action games before will recognise all the mechanics at play in this scenario, but it was still well executed and effective. Another had a whiff of Star Wars, as you rush around shooting electrical panels to stop a trash compactor from crushing you via the descending ceiling. The action shift in Unfinished Business is best defined by a later sequence we got to play, where you take control of the franchise’s signature mech, ED-209. If the power fantasy of playing as RoboCop is tested in this expansion, ED-209’s section was pure mental catharsis, where you blast away enemy hordes with miniguns and rockets, and clean up any stragglers with a rigid, robotic stomp. The rush of piloting ED-209, with its cacophony of explosions and bullets, felt like a throwback to vehicle sections in a long lost Xbox 360 game – but in a good way.  While there’s a definite lean towards combat, rather than gift card signing, when compared to Rogue City, it hasn’t entirely abandoned the detective side. According to the developers, if Rogue City had a 60/40 percent split between guns and detective work, Unfinished Business ‘would be like 70/30, or 80/20’ in comparison. More Trending We saw some of this , with one memorable encounter seeing you quizzed by a RoboCop superfan who is unconvinced you’re the actual RoboCop, leading to a series of questions based on the history of the franchise. There is optional side missions too, although the time we had with our preview limited our chance to fully delve into them. The sales and positive reviews for RoboCop: Rogue City emboldened Teyon’s vision and scope for Unfinished Business – and that confidence shines through in what we played. Some might be disappointed by the steer towards action, and we were heading into this preview, but by the end, this felt like a welcome extension with its own unique flavour. This is RoboCop: Rogue City with its pedal to the floor, confined and concentrated into a lean, tightly focused machine.  As for the studio’s next steps, the success of RoboCop has only reaffirmed Teyon’s strengths and identity as a team. Between its three studios across Poland and Japan, with over 140 employees in total, Teyon wants to maintain its grip within the AA space. ‘We feel strong here in such games,’ Biegun said. ‘We wouldn’t want to grow like 200, 300, 400 people, because we’re going to lose our soul this way. We want to stay as we are right now.’ ED-209 needs be wary of stairs (Nacon) Email gamecentral@metro.co.uk, leave a comment below, follow us on Twitter, and sign-up to our newsletter.
