Plug the gaps in your network’s infrastructure with resilient network security models Key FeaturesDevelop a cost-effective and end-to-end vulnerability management programExplore best practices for vulnerability scanning and risk assessmentUnderstand and implement network enumeration with Nessus and Network Mapper (Nmap)Book Description Digitization drives technology today, which is why it’s so important for organizations to design security mechanisms for their network infrastructures. Analyzing vulnerabilities is one of the best ways to secure your network infrastructure. This Learning Path begins by introducing you to the various concepts of network security assessment, workflows, and architectures. You will learn to employ open source tools to perform both active and passive network scanning and use these results to analyze and design a threat model for network security. With a firm understanding of the basics, you will then explore how to use Nessus and Nmap to scan your network for vulnerabilities and open ports and gain back door entry into a network. As you progress through the chapters, you will gain insights into how to carry out various key scanning tasks, including firewall detection, OS detection, and access management to detect vulnerabilities in your network. By the end of this Learning Path, you will be familiar with the tools you need for network scanning and techniques for vulnerability scanning and network protection. This Learning Path includes content from the following Packt books: Network Scanning Cookbook by Sairam JettyNetwork Vulnerability Assessment by Sagar RahalkarWhat you will learnExplore various standards and frameworks for vulnerability assessments and penetration testingGain insight into vulnerability scoring and reportingDiscover the importance of patching and security hardeningDevelop metrics to measure the success of a vulnerability management programPerform configuration audits for various platforms using NessusWrite custom Nessus and Nmap scripts on your ownInstall and configure Nmap and Nessus in your network infrastructurePerform host discovery to identify network devicesWho this book is for This Learning Path is designed for security analysts, threat analysts, and security professionals responsible for developing a network threat model for an organization.

In today's digital world, where remote working is becoming increasingly common, it is crucial to understand the importance of network security. With the rise of cyber threats and the adoption of hybrid working models, organizations and individuals must prioritize their cybersecurity to protect sensitive data and maintain business continuity. Network security refers to the measures taken to protect a computer network from unauthorized access, disruption, or misuse. It encompasses various technologies, policies, and practices that safeguard network infrastructure, data, and devices from malicious activities. One of the key reasons why network security is of utmost importance is the protection of sensitive information. In a hybrid working environment, employees access and share data from various locations and devices. This increased mobility and connectivity also create potential vulnerabilities that can be exploited by cybercriminals. By implementing robust network security measures, such as firewalls, encryption protocols, and secure remote access, organizations can ensure the confidentiality, integrity, and availability of their data. Another critical aspect of network security is the prevention of cyber attacks. Cyber threats, such as malware, ransomware, and phishing attacks, continue to evolve and target both individuals and organizations. Without adequate network security measures in place, employees and their devices become easy targets for these malicious activities. Implementing strong authentication protocols, regular software updates, and employee awareness training can significantly reduce the risk of falling victim to cyber attacks. Network security is also essential for business continuity. In a hybrid working environment, organizations heavily rely on network infrastructure to communicate, collaborate, and access critical resources. Any disruption or compromise in network security can result in downtime, financial losses, and reputational damage. By investing in network security solutions, organizations can mitigate these risks and ensure uninterrupted operation
