Security Analysis: Network Vulnerability Assessment -- 2

@AZTURK1

Hi there, I can see you're looking for a structured Network Vulnerability Assessment covering discovery, port enumeration, and risk classification with actionable remediation steps. I'll perform a thorough scan using Nmap, identify exposed services and misconfigurations, and deliver a professional report with evidence and priority-based findings. What I'll do: ✅ Conduct network discovery and port/service enumeration with Nmap ✅ Identify outdated software, insecure configs, and high-risk exposures ✅ Deliver a detailed report with risk levels, evidence, and hardening recommendations ✅ Always backup configurations and test in a safe manner before recommending changes Skills block: ✅ Network Security & Vulnerability Assessment (Nmap, Nessus, OpenVAS) ✅ DNS, TCP/IP, HTTP/HTTPS, SSH, SMTP protocol analysis ✅ Firewall & network device hardening (pfSense/MikroTik/FortiGate) ✅ Risk Assessment & Security Reporting ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ 300+ projects delivered, 280+ five-star reviews Why me: I have 7+ years hardening production networks and delivering security reports for enterprise clients. Quick question: Is this assessment for an on-premises network, a cloud-hosted environment (AWS/Azure), or a hybrid setup? This will help me tailor the scanning approach and reporting format. I can deliver in 7 days for 111,500 INR and can start right now.

HI, KINDLY READ THROUGH MY PROPOSAL I will perform a structured Network Vulnerability Assessment on your authorized network environment to identify security weaknesses and provide clear, practical remediation recommendations. MY APPROACH ✅ Network discovery and topology mapping ✅ Port & service enumeration ✅ Architecture and protocol analysis ✅ Vulnerability identification using authorized scanning tools ✅ Risk prioritisation and actionable security recommendations ✅ Professional report with methodology, findings and remediation steps DELIVERABLES - Complete vulnerability assessment report - Risk-ranked findings with evidence - Practical remediation recommendations - Summary of network structure and exposed services IMPORTANT This work will only be performed on systems and networks for which you have explicit written authorization. QUESTIONS 1. Do you already have written authorization for the assessment? 2. Approximate size of the network (number of hosts / subnets) and any preferred scope boundaries? Ready to start once authorization and scope are confirmed.

Hi — happy to take this on. The scan itself is straightforward; what makes an assessment useful is a report that ranks findings by exploitability in your actual topology rather than by raw CVSS, since a critical on an isolated host matters far less than a medium on something internet-facing. I'd cover discovery, port and service enumeration, protocol review and configuration issues, then deliver findings with evidence, ranked remediation with effort estimates, and a re-test checklist so you can verify the fixes yourself afterwards. Happy to include a short summary page written for non-technical stakeholders alongside the technical report. - Roughly how many hosts are in scope? - Credentialed or black-box? They give quite different results. Happy to discuss and get the authorisation scope agreed first.

I’d like to handle this assessment with a focus on finding security issues that are actually useful for your team to fix. I’ll start by mapping the authorized network and identifying live hosts, open ports and services, followed by architecture and protocol analysis. From there, I’ll assess exposed services, outdated software and insecure configurations, validate the relevant findings, and prioritize them based on risk. The final report will include clear evidence for each finding, risk level, impact and practical remediation recommendations for hardening, patching, firewall and access controls. I have 4+ years of hands-on IT and security experience and can start immediately.

Mapping an authorized network from live-host discovery through to a prioritized remediation report is mostly about scoping discipline and clear write-ups, and that's where I'd put the effort. My security work has been web application penetration testing and security audits, scoring findings with CVSS and mapping them to OWASP Top 10, plus a past role analyzing vulnerabilities in widely used open source Python packages. I've spent 8 years in software engineering on Linux and Docker environments, so reviewing exposed services, outdated software and weak configurations on servers is familiar ground, and I'd rank each finding by impact so your team knows what to patch first. One question before scoping: is this an internal network I'd reach over VPN or on site, or only externally facing ranges, and do you already hold written authorization covering the IP scope? That changes the discovery approach and how much of the architecture review can happen hands-on. Thamer

HI, Rahul this side. I am based in Lucknow, India, so this can also be helpful if there is any requirement for physical or on-site visit. I have 13 years of experience in IT infrastructure, with strong hands-on knowledge in networking, Linux, firewalls, virtualization and cloud platforms. Because I have worked across these different areas, I dont just look at a vulnerability from the network point of view, but can also understand what is causing the issue and how it can be fixed. Final report will include the methodology, discovered hosts/services, vulnerabilities, evidence, severity/risk level, impact and practical remediation steps.

@niguelclarkb

Hi, I read through your scope for the network vulnerability assessment. I'm a CCNA/CCNP ENCOR certified network engineer, and I recently built and currently maintain a segmented security monitoring lab (Wazuh for host-based detection and log collection, Zabbix for infrastructure monitoring, Suricata for network intrusion detection) on a GNS3-simulated enterprise topology with VLAN-segmented zones, which lines up closely with the network discovery, protocol analysis, and architecture review your assessment needs. My approach: map the topology and IP/subnet plan, run host discovery and Nmap-based port/service enumeration, review router/switch/firewall configs for insecure settings, check core protocols (TCP/IP, HTTP/HTTPS, SSH, DNS, DHCP, FTP/SFTP, SMTP) for exposure, then classify findings by risk and deliver a clear report with methodology, evidence, and practical remediation steps (patching, hardening, firewall/ACL tightening). Happy to confirm scope and authorized testing boundaries before starting.

@mengw3

I've spent 20+ years working across networking, systems administration, and security tooling, so TCP/IP, routing, subnetting, and the protocol stack you listed (SSH, DNS, DHCP, FTP/SFTP, SMTP, HTTP/HTTPS) are familiar ground. My toolkit for this kind of work is Nmap, Wireshark, OpenVAS/Nessus, and CVE/NVD cross-referencing to turn scan output into real findings. The hard part here is telling actual exploitable risk apart from scan noise without knocking anything over on a live network. - Nmap ping sweep for live hosts, then -sV -sC for service and version fingerprinting on open ports - Map the topology by hand: routers, switches, firewalls, servers, clients, and how they sit relative to each other - Check each service against CVE/NVD for issues tied to the exact version found, not just the port number - Pull traffic samples with Wireshark to confirm which services actually send plaintext (FTP, unencrypted SMTP) vs just claiming to - Score findings by CVSS-style severity and tie each one to a fix: patch version X, disable service Y, tighten firewall rule Z You'll get a written report with methodology, evidence (screenshots, packet captures), a risk table, and remediation steps you can hand straight to whoever owns the infrastructure. One question before I start: do you already have the IP ranges and a signed scope/authorization document, or do we need to nail that down first? I can start right away.

Hello, I’d be interested in performing the Network Vulnerability Assessment and Security Analysis of your authorized network environment. My approach begins with network discovery and topology understanding, followed by host identification, port/service enumeration, protocol analysis, and assessment of exposed services and configurations. I use tools such as Nmap, Wireshark, and other authorized security-testing tools, while manually validating important findings rather than relying solely on automated scanners. I will assess areas including network devices, servers, endpoints, exposed services, insecure configurations, outdated software, unnecessary services, and relevant access-control/security weaknesses within the agreed scope. Each confirmed finding will be documented with evidence, affected assets, risk/impact, technical details, and practical remediation guidance. The final report will provide both a clear executive overview and detailed technical findings, allowing technical teams to reproduce and address the issues. I will work strictly within the authorized scope and avoid disruptive or destructive testing. I have hands-on experience in network and web application penetration testing and can provide my security portfolio and sample assessment reports. Estimated timeline: 4–7 business days, depending on network size and scope. Bid: ₹100,000 INR I’d be happy to review the scope and requirements before starting.

@OlegUV

Your brief reads like a service description rather than a scope, so before I quote seriously I need three answers: how many live hosts and public IPs are in scope, is this the internal network, the external perimeter or both, and who signs the authorization for the testing. I run assessments from a Kali environment: discovery and port enumeration with Nmap, service and version checks, then verification by hand, because scanners flag plenty that is not actually exploitable in your setup. You get methodology, evidence, risk levels, a remediation order, and a re-test after you patch. Twenty years on Linux servers, four of them in government IT security. I can start with a small scoped block so you see the reporting quality before you commit the full budget.
