Safer and More Efficient Self-Teaching Cyber Security and Hacking Techniques

If you want to learn network security (hacking technology) well , you must first know them:

Cybersecurity is:

Network security refers to a series of measures and technologies to protect computer networks and their related equipment, systems, data and information transmitted in the network from unauthorized access, use, modification, destruction, interference or disclosure.

The goal of cybersecurity is to ensure the confidentiality, integrity, and availability of computer networks to prevent threats such as illegal activities, malicious attacks, data breaches, and service interruptions. Cybersecurity covers a variety of security domains, including network infrastructure security, information security, application security, physical security, and more.

Hacking technology refers to the use of technical means by professionals familiar with computer system and network security to discover system loopholes and weaknesses through analysis and research on computer systems and networks, in order to obtain unauthorized access, control or modify target systems or data. ability.

Hacking techniques are:

Hacking techniques can be divided into the following categories:

1. Penetration testing: Also known as vulnerability assessment, hackers test and evaluate the security of target systems and networks in an authorized manner, and discover and exploit system vulnerabilities.

2. Network attack: Hackers use various technical means, such as port scanning, denial of service attack (DoS/DDoS), ARP spoofing, man-in-the-middle attack, etc., to attack the target network, disrupt its normal operation or obtain information illegally.

3. Social engineering: Hackers use social engineering techniques, such as camouflage, deception, misleading and other means, to deceive target users through human weaknesses and trust, so as to gain access to the system or sensitive information.

4. Worms and viruses: Hackers develop malicious software, such as worms, viruses, Trojan horses, etc., to attack, steal information or spread by implanting into the target system.

5. Password cracking: Hackers use various technical means, such as brute force cracking, dictionary attacks, etc., to crack encrypted passwords and gain access to the system.

It is worth noting that hacking technology is not a legal act, but an illegal attack. The purpose of hacking technology may be to illegally obtain information, illegally obtain property, and destroy system stability. For security practitioners, they usually test and evaluate systems and networks in a legally authorized and compliant manner to discover and fix possible security vulnerabilities.

The relationship between network security and hacking techniques:

Network security and hacking are closely related, but they are completely different concepts .

Network security refers to a series of measures and technologies to protect network systems, network data and network communications from unauthorized access, use, interference, destruction, theft or tampering . Its goal is to ensure that the confidentiality, integrity and availability of networks and network resources are not compromised.

Hacking refers to the use of computer technology and programming skills to explore and exploit security vulnerabilities to gain unauthorized access or control . Hacking techniques can be divided into legal and illegal forms. Legitimate hacking techniques are used by security experts and white hat hackers to reveal and fix security holes in a system. Illegal hacking techniques are used by hackers to illegally obtain sensitive information of others or damage network systems.

Therefore, network security and hacking technology are interrelated. The goal of network security is to protect the network from hacker attacks, while hacking technology is to improve the ability of network security by studying the security loopholes of network systems. Legal hacking techniques play a positive role in the field of network security, but illegal hacking techniques pose a threat to network security.

Misunderstandings and pitfalls of self-study network security learning:

1. Lack of system : Network security is a huge field that includes many different aspects, such as cryptography, network attack and defense, malware analysis, etc. If you just learn some scattered knowledge points at will, it is difficult to build a systematic understanding and ability. Therefore, it is recommended to formulate a study plan to systematically study various fields of network security and accumulate relevant practical experience.

2. Ignore basic knowledge : Before learning network security, it is recommended to lay a solid foundation of basic computer knowledge, including operating systems, network principles, programming languages, etc. These fundamentals are important for understanding and applying the concepts and techniques of cybersecurity.

3. Too much reliance on tools : There are many powerful tools and software in the field of cybersecurity that can help with various experiments and tests, but too much reliance on these tools can lead to insufficient understanding of principles and concepts. Therefore, while using tools, you must have a deep understanding of their principles and usage methods, and don't rely too much on them.

4. Lack of practical experience : Network security is a practice-oriented field, and relevant technologies and skills can only be truly mastered through practical experiments and drills. Therefore, you must pay attention to practice during the learning process. You can try to build an experimental environment, participate in CTF competitions, and join the security community to gain practical experience.

5. Illegal Behaviors : The purpose of network security is to protect network and information security. Therefore, in the process of learning and practice, we must abide by laws and ethics. Do not participate in any illegal activities, such as hacking, unauthorized penetration testing, etc., and should maintain a legal and ethical learning attitude.

In general, self-learning network security requires a systematic study plan, focusing on basic knowledge, not relying too much on tools, focusing on practical experience, and always abiding by laws and ethics.
