The importance of protecting data has brought in focus the need for implementing information security by using the most advanced technologies and techniques to keep systems safe and secure. The demand for information security professionals is driving more people to acquire IT security career certification. Moreover, as technology is advancing rapidly so also are the techniques of hacking and data thefts. They are becoming more sophisticated as evident from the reports of several major data breaches that have happened in recent times. It makes it imperative that even professionals working in any area of information security must upgrade their knowledge and skills to counter the threats effectively by obtaining some professional certification.
The scope of learning
Many courses are available for learning information security that covers various aspects but to make a career you must choose a course that introduces you to the subject from the basics and covers all aspects that prepare you for starting a career. It should help you to identify major information security issues and trends and chart out the course of action for preventing it. Once you make a start, you can take advanced training in some specialized area that is relevant to your job.
The course should cover the following.
Computer security and cryptographic concepts
You learn about the basic concepts of integrity, confidentiality, and availability and understand threats, attacks, and assets in the context of management of security. You also learn about cryptography, the science behind data encryption and the concepts of cryptography and its purpose.
Public key encryption
This unit deals with the exploration of basic cryptographic concepts that exposes you to the techniques of asymmetric key encryption based on the concepts of the public key. It should help you to compare and understand the difference between symmetric algorithms and public key algorithms.
Access control mechanisms
To control access to some areas of a physical facility or computer-based information system you must have an access control mechanism in place. You will learn about user authorization used for implementing the system.
In this unit, you will learn about the current security solutions that are in use. You will learn about SSL (Secure Sockets Layer) a trusted web-based application for securing E-Commerce or other websites that engage in financial transactions.
Intrusion detection, prevention, and firewalls
Firewalls are security tools, and you learn about it as well as other intrusion prevention systems. You learn how to secure communication systems by using firewalls.
Learning about Malware and common software security issues such as buffer flow, a technique used by several malware to identify the vulnerability of systems will teach you about the use of malware to wage war against system attacks.
Security Risk Management
The learning from this module will help you to identify the vulnerabilities in the information system and take adequate steps to protect the various components of the system by maintaining its integrity, confidentiality, and availability.
Learning about physical security teaches you how to protect hardware, software, networks, data, and personnel from events and circumstances that can cause damage or losses.
