Cybersecurity is a vast field that has to do with securing every nook and cranny of our digital world. It has a lot of subjects in it that deal with different parts of the security process. Whether it is securing the network, or finding digital evidence against a ransomware attack, if you plan to enroll for a Certified Ethical Hacker i.e. CEH course or a Network Defense course, you will have to know a little bit about everything that is covered in information security. No matter where you end up in your career, in the long run, depending on your area of specialization, these are things you will have to go through in your information security career.
1. Network Defense – Securing the Perimeter of Digital Systems
Network defense is a whole discipline in itself. Securing the perimeter of a structure is one of the key steps in securing digital systems. Network security deals with traffic monitoring, intrusion detection systems, endpoint security, wireless security, firewalls, and much more. To start learning cybersecurity, you need to understand this basic pillar of safety. With COVID-19, the perimeters of organizational defense have changed drastically, making old network security practices obsolete in remote work arrangements.
2. Penetration Testing – Finding Vulnerabilities to Fix the Overlooked Loopholes
Ethical hacking, white-hat hacking, friendly hacking are all interchangeable terms. And penetration testing is a similar area that occupies the offensive cybersecurity space. Learning information security is not just about learning defensive techniques, it also requires a deep understanding and application of offensive security practices. In an ethical hacking course, you will get to learn about hacking into systems to find vulnerabilities and security issues in source codes, configurations, etc.
3. Incident Responding – Knowing How to Manage a Crisis Situation
Incident response is another major area of information security. Responding to crises and mitigating cyber disasters plays a key role in this field. As a cybersecurity student, you will need to understand the practices and techniques to protect a digital system during a cyber attack. Vulnerability handling, data loss prevention, and forensic readiness are some subjects you will be familiarising within your training.
4. Forensic Analysis – Digital Detectives to Trace Down the Criminals
Forensic investigation is a whole different game. Digital evidence recovery, analysis, documenting the findings, legal practices, and using the evidence in the court of law, are a few things that forensic investigators must know. Forensic analysis studies also deal with hard disks and file systems as they are related to data recovery.
5. Cyber Laws and Ethics – Legal Practices in the Cyber World
Cyber laws and ethics are an important part of cybersecurity. Being on the noble side of the spectrum, you will need to understand the cyber laws, privacy laws, data protection laws, and ethics practiced in different states, countries, and parts of the world.
6. Cyber Risk Management – Minimizing Information Risks
Risk management is an important part of information security. The whole point of cybersecurity is to minimize and manage cyber threats and risks. Identifying risks as accurately as possible, and planning techniques to avoid them along with monitoring the results is what risk management is all about.
Organizations today invest significantly in cyber risk management, ethical hacking, network security, and other cybersecurity practices. Whatever you choose to specialize in later in your career, will help you become an expert in your chosen domain and cement your place as a specialized professional with a deep understanding of the area. However, in the beginning, it will benefit you to learn and understand all the areas as much as you can and get n overall perspective of the world of cybersecurity.
