In my role as a SOC analyst, part of my weekly responsibilities includes conducting vulnerability assessments. This involves scanning and identifying vulnerabilities within systems and applications using tools like Rapid7. Additionally, I manage patching to ensure that software updates are applied promptly, addressing known vulnerabilities. My primary focus is on vulnerability assessment. My objective is to mitigate the risk of exploitation by minimizing the time between the discovery of vulnerabilities and their remediation. Once vulnerabilities are identified through our Rapid7 scans, I create tickets in our Jira system, prioritizing the Top 10 riskiest assets based on their vulnerability scores. I collaborate with our helpdesk team, requesting them to establish communication with asset owners to address vulnerabilities with a risk score of 1000 or higher. As the helpdesk initiates contact, I update the Jira ticket workflow from "Needs Attention" to "In Progress." Once the vulnerabilities have been addressed, the helpdesk updates the ticket to "Pending Validation." At this stage, I re-scan the assets using Rapid7 to ensure that the vulnerabilities have been effectively resolved before returning the assets to their owners. Finally, I update the Jira ticket workflow to "Resolved. #stayinformed #connectwithme. #cybersecurityisajourneynotadestination

Streamlining vulnerability assessments is often overlooked, but overcomplicating things doesn't make you smarter. I recently chatted with an MSSP about this. They had a 20-page assessment process. Crazy, right? No one's going to read, understand, or use that. You need to be able to explain your assessment strategy simply - both to your team and your clients. Here's how I suggested they approach it: 1. Be EFFICIENT. Assess just 10-20 key client computers for a good sample. 2. Show VALUE fast. Secure one machine to demonstrate the before/after impact. 3. Use AUTOMATION wisely. Look for tools that combine scanning, prioritization, and fixes in one platform. 4. Create CLEAR reports. Show decision-makers real improvements in security. 5. Turn assessments into SALES opportunities. Offer paid assessments, then propose ongoing managed services. Or the opposite: Give the assessment for free, then remediate as an upsell (This is the approach we love at Vicarius) 6. Stick to STANDARDS. Link findings to recognized benchmarks like CIS for credibility. 7. Cover MULTIPLE bases. Look at vulnerabilities, misconfigurations, cloud security, etc. 8. Offer CHOICES. Present good/better/best options tailored to each client. The goal is to have a smooth, repeatable process that clearly shows value to clients. With the right approach, MSSPs can use assessments to grow their managed security business effectively. What other ideas do you have for simplifying security assessments? I'm curious to hear your thoughts.

🚨 Mastering IT Risk Assessment: A Strategic Framework for Information Security In cybersecurity, guesswork is not strategy. Effective risk management begins with a structured, evidence-based risk assessment process that connects technical threats to business impact. This framework — adapted from leading standards such as NIST SP 800-30 and ISO/IEC 27005 — breaks down how to transform raw threat data into actionable risk intelligence: 1️⃣ System Characterization – Establish clear system boundaries. Define the hardware, software, data, interfaces, people, and mission-critical functions within scope. 🔹 Output: System boundaries, criticality, and sensitivity profile. 2️⃣ Threat Identification – Identify credible threat sources — from external adversaries to insider risks and environmental hazards. 🔹 Output: Comprehensive threat statement. 3️⃣ Vulnerability Identification – Pinpoint systemic weaknesses that can be exploited by these threats. 🔹 Output: Catalog of potential vulnerabilities. 4️⃣ Control Analysis – Evaluate the design and operational effectiveness of current and planned controls. 🔹 Output: Control inventory with performance assessment. 5️⃣ Likelihood Determination – Assess the probability that a given threat will exploit a specific vulnerability, considering existing mitigations. 🔹 Output: Likelihood rating. 6️⃣ Impact Analysis – Quantify potential losses in terms of confidentiality, integrity, and availability of information assets. 🔹 Output: Impact rating. 7️⃣ Risk Determination – Integrate likelihood and impact to determine inherent and residual risk levels. 🔹 Output: Ranked risk register. 8️⃣ Control Recommendations – Prioritize security enhancements to reduce risk to acceptable levels. 🔹 Output: Targeted control recommendations. 9️⃣ Results Documentation – Compile the process, findings, and mitigation actions in a formal risk assessment report for governance and audit traceability. 🔹 Output: Comprehensive risk assessment report. When executed properly, this process transforms IT threat data into strategic business intelligence, enabling leaders to make informed, risk-based decisions that safeguard the organization’s assets and reputation. 👉 Bottom line: An organization’s resilience isn’t built on tools — it’s built on a disciplined, repeatable approach to understanding and managing risk. #CyberSecurity #RiskManagement #GRC #InformationSecurity #ISO27001 #NIST #Infosec #RiskAssessment #Governance

A new ICS/OT vulnerability? PATCH NOW! Wait... scratch that... Reverse it. Vulnerability management is VERY different in the ICS/OT world. In the IT world, a new patch comes out and it's off to the races! - We're patching servers. - We're rebooting servers. - We're patching workstations. - We're rebooting workstations. - We're patching everything we can get our hands on. You get the idea. In ICS/OT, just because a new vulnerability is announced, it does not mean we have to patch right away. We might not even have an option to patch a system until the next maintenance window. In six months. Or a year. If ever. When that new ICS/OT vulnerability is announced, we still have to take action though. It's just a different action than in IT. When a new ICS/OT vulnerability is announced: 1. Determine if it affects your environment. This is why having a current asset register is essential. 2. If the vulnerability exists in your environment, perform a risk assessment. Consider questions including, but not limited to: -> Which systems are impacted? -> Where do the impacted systems live? -> Do compensating controls exist to reduce the risk? -> Does the vulnerability put lives/physical safety at risk? -> Could the vulnerability affect the operations of the facility? -> What would be the impact if the vulnerability was exploited? NOTE: When assessing risk, get all of the right people in the room to help make an informed decision. Engineering, operations, maintenance, cyber security, etc. 3. Based on the risk assessment, and the owners risk tolerance: -> Do you need to take action? -> If so, how soon? IT and OT can have MANY similarities. But IT and OT can also be VERY different. Vulnerability management is one of the ways where they are very different. And each requires a different approach to maintain secure, and SAFE, environment. P.S. How does your vulnerability management process work?

🚨 Why Vulnerability Assessment & Penetration Testing (VAPT) is a Game-Changer in Cybersecurity? In my journey of exploring advanced cybersecurity practices, I recently studied a comprehensive Lab Manual on VAPT, created under the Ministry of Electronics & Information Technology, Government of India. It provided deep insights into how organizations can safeguard themselves against evolving cyber threats. Here’s a quick guide for anyone curious about VAPT ⬇️ 🔎 What is VAPT? - Vulnerability Assessment (VA): Identifies weaknesses in systems, applications, and networks. - Penetration Testing (PT): Simulates real-world attacks to exploit vulnerabilities and measure actual risk impact. ⚡ Why is VAPT Important? - Firewalls & HTTPS are not enough – attackers easily bypass them. - Reveals gaps that scanners & policies miss. - Provides a realistic picture of security posture. - Helps organizations protect reputation, customers, and business continuity. 🛠 Core Areas Covered in VAPT ✔️ Network Vulnerability Testing – Scanning and securing critical infrastructure. ✔️ Web Application Testing – Detecting OWASP Top 10 vulnerabilities like SQLi, XSS, etc. ✔️ Wireless Security – Identifying rogue or weakly encrypted access points. ✔️ Social Engineering / Phishing – Testing human factors in security. ✔️ Physical Security Audits – Assessing locks, access controls, and data disposal practices. 📌 Key Methodology 1️⃣ Planning & Scope Definition 2️⃣ Footprinting & Reconnaissance 3️⃣ Exploitation (Proof of Concept) 4️⃣ Reporting & Remediation Guidance 💡 Takeaway: Cybersecurity isn’t just about prevention; it’s about active testing. If a vulnerability exists, someone will find it – the only question is whether it’s an attacker or a security professional. As a cybersecurity enthusiast, studying this manual gave me not only theoretical clarity but also practical steps to apply in real-world penetration testing. This motivates me further to strengthen my skills in ethical hacking, red teaming, and bug hunting. 🔐 Let’s continue to build a safer digital future by thinking like attackers and defending like professionals. #CyberSecurity #VAPT #PenetrationTesting #EthicalHacking #Infosec #WebSecurity #BugBounty #RedTeam #ISO27001
