Basics of linux which isessenstial to know!
Lear how does filesystem layout looks like!
Lets see demo of linux filesystem !
Lets learn some linux commands!
Explore id and group ids in Linux, add users with sudo add user, view /etc/passwd via cat and cut, modify with usermod, switch users, and check who is logged on.
Asymmetric cryptography uses public and private keys to encrypt and decrypt data, enabling authentication and non-repudiation while aiding secure key distribution with algorithms like RSA, ECDSA, and Diffie-Hellman.
Learn to extract inputs from a log, identify timestamps, and convert unix timestamps in seconds to UTC format using CyberChef recipes and the bake button.
Apply the magic operation to detect input data properties and generate decoding recipes, revealing a base 58 encoded message decoded by a cipher recipe and clarifying entropy and file types.
Demonstrates pbkdf2, a password based key derivation function used with RSA public key cryptography; adjust key size, iterations, and salt to influence the derived output.
Engineers use OpenSSL to generate private keys and certificates, enabling secure, authenticated communication between power plant and substation controllers in the Cyberland use case.
Learn to verify software integrity and authenticity by hashing downloaded files with sha-256 (and md5 if available), comparing against provided hashes, and confirming matches via a simple terminal command.
Apply a latency-aware approach to industrial control network segmentation by using an l3 switch to reduce hops and enable inter-vlan routing, improving latency and stability.
Explore physical and logical network segmentation, including VLANs, IPS, proxies, and ACLs, contrasted with air gapping, data diodes, firewalls, switches, and Faraday cages.
Review and update the incident response plan after resolution to capture lessons learned. Conduct root cause analysis and assess response effectiveness, using tabletop exercises to spot quick wins and shortfalls.
Welcome to the sequel course of previous part!!
Get ready to dive deep into the fascinating realm of Linux, Cryptology, Secure Network Design, Cybersecurity Management, Incident Response, and Contingency and Continuity in this comprehensive Udemy course.
Linux: Unveil the power of Linux as you explore its family tree and delve into the intricate filesystem layout. Put your skills to the test with hands-on labs that will sharpen your expertise in Linux commands.If you don't have Linux machine ask me, I can give you access for that or create on Azure.
Endpoint Security: Safeguarding your systems is paramount, and this course equips you with the knowledge to protect them. Learn about antivirus software, host-based firewalls, EDR (Endpoint Detection and Response), DLP (Data Loss Prevention), and application allowlisting.(To be added later)
Cryptology: Discover the secrets of encryption and digital security. Explore various cryptography methods, including symmetric and asymmetric key algorithms, hashing, and digital signatures. Unleash the power of Cyberchef tools and dive into firmware analysis with Binwalk.
Secure Network Design: Understand the functional differences in network design and explore use cases for effective network segmentation. Study reference architectures that will help you build robust and secure network infrastructures.
Cybersecurity Management: Learn the key components of a NIST Cybersecurity Program and explore the impact of cybersecurity on manufacturing systems. Dive into cybersecurity frameworks, standards, and policies that guide industry best practices.
Incident Response: Gain invaluable insights into incident response strategies. Compare NIST and SANS methodologies, and master the art of preparation, identification, containment, eradication, recovery, and learning from past incidents.
Contingency and Continuity: Explore different types of plans and discover how business continuity and contingency planning ensure the resilience of organizations. Perform a Business Impact Analysis (BIA) and learn about disaster recovery (DR) strategies.
This course is designed to provide you with a comprehensive understanding of essential cybersecurity concepts and practical skills. You'll have the opportunity to test your knowledge through engaging lab exercises and thought-provoking questions. (To be added)
