Edureka’s Cybersecurity Certification Course will help you in learning about the basic concepts of Cybersecurity along with the methodologies that must be practiced ensuring information security of an organization. Starting from the Ground level Security Essentials, this course will lead you through Cryptography, Computer Networks & Security, Application Security, Data & Endpoint Security, idAM (Identity & Access Management), Cloud Security, Cyber-Attacks and various security practices for businesses. ------------------------------------------------ Why Learn Cyber Security? Cybersecurity is the gathering of advances that procedures and practices expected to ensure systems, PCs, projects and information from assault, harm or unapproved get to. In a processing setting, security incorporates both cybersecurity and physical security, it is imperative since cyberattackers can without much of a stretch take and obliterate the profoundly grouped data of governments, defense offices and banks for which the results are huge so it is essential to have an appropriate innovation which an avoid digital wrongdoings. --------------------------------------------------- Objectives of Edureka Cyber Security Course This course is designed to cover a holistic & a wide variety of foundational topics of the cybersecurity domain which will be helpful to lead freshers as well as IT professional having 1 to 2 years of experience, into the next level of choice such as ethical hacking/ audit & compliance / GRC/ Security Architecture and so on This course focuses mainly on the basics concepts of Cyber Security In this course, we are going to deal with Ground level security essentials cryptography, computer networks & security, application security, data & endpoint security, idAM (identity & access management), cloud security, cyber-attacks and various security practices for businesses This course will be your first step towards learning Cyber Security -------------------------------------- Who Should go for this Training? Anyone having the zeal to learn innovative technologies can take up this course. Especially, students and professionals aspiring to make a career in the Cybersecurity technology. However, Cybersecurity Certification Course is best suited for the below mentioned profiles:- Networking Professionals Linux Administrators ----------------------------------------------- For more information, Please write back to us at sales@edureka.in or call us at IND: 9606058406 / US: 18338555775 (toll-free).
