I am working on a research paper in the area of Wireless Sensor Network security and need a simple, runnable simulation model for Hello Flood attack detection. The work involves creating a small WSN simulation (10–50 nodes) using Cooja/Contiki or NS-3, where one or more malicious nodes perform a Hello Flood attack. A basic detection technique (threshold-based , energy-based , etc) should be implemented to identify the attacker. After creating the model, you should also explain and show basic performance metrics such as detection accuracy, precision/false positives (if possible), and energy consumption, so the results can be compared with existing research papers. The focus is on academic experimentation, not a complex or commercial system.

I want to sit down—virtually—with an experienced IT professional for two focused hours on Saturday and again on Sunday to review every online tool my company relies on. The immediate goal is to tighten cybersecurity, verify that our backups are both complete and retrievable, and make sure we maintain full control over all domains, SaaS logins, cloud drives, and other digital assets. We already have a few security measures in place, but they are patchy. What worries me most right now is user-access control: who can touch what, how passwords are stored, and whether multifactor authentication is enforced everywhere it should be. During our sessions we will log in together, map out each system, and plug any obvious holes. If you spot deeper issues, outline them so we can plan long...

I need a Check Point firewall engineer to configure between one and three VLANs on an existing appliance so that my Ruckus WIFI - SSID traffic is properly segregated from the rest of the network. The hardware is already racked and running the latest fireware; what’s missing is the VLAN definition, interface tagging, and any associated security policies. Scope of work • Create the required VLAN interfaces on the gateway and assign the correct IP addressing schema I will provide. • Adjust or build the security rules so that only approved inter-VLAN flows are allowed. • Verify reachability to and from the server network and document the final topology (screenshots of SmartConsole and a brief change log are fine). Acceptance criteria • All Ruckus WIFI - SSID...

Our ZeroTier network crawls when two client machines talk directly to each other, even though both reach the internet at normal rates. The slowdown is consistent and reproducible between these specific nodes; transfers to or from the central server are fine. I need someone who understands ZeroTier routing, MTU tuning, and peer-to-peer paths to pinpoint what is throttling bandwidth and then implement (or clearly outline) the fix. You will have temporary access to configuration screens and can guide me through any packet captures or command-line checks you require (tcpdump, Wireshark, zerotier-cli, etc.). A quick turnaround is important because this link is part of a production workflow. Deliverables • Clear diagnostic report showing root cause of the slow client-to-client transfer ...
