The internet has become a very important part of our lives. We use it for everything, from connecting with others through social media websites like Facebook to shopping online at Amazon, storing data in the cloud, or even controlling our homes, etc., so we must save it from many problems. One of the main problems is cyber attacks. To solve this problem, we need the cyber security field.
What is cyber security?
Cyber security means protecting information technology systems and data from attacks. Those systems include things like computers, servers, mobile devices, networks, and anything that stores or transmits data.
Why is cyber security so important?
Cyber security is very important for several reasons:
- Pervasive Reliance on Technology: Our lives are increasingly dependent on technology, from online banking to medical records and critical infrastructure. Cyber security prevents that data from falling into the wrong hands.
- Rising cyber crime: Attackers are always developing new methods to steal data and disrupt operations. Strong cyber security makes it harder for them to succeed.
- National Security: Cyber security is crucial for national security. Critical infrastructure like power grids and communication networks is being targeted by cyber attacks that could cause widespread disruption
What are the common types of cyber attacks?
Understanding the different types of cyber attacks is essential for building a strong defense. The following are a few of the common dangers you need to be careful of:
- Phishing attacks: Phishing attacks include the use of fake emails or messages to trick users into opening dangerous attachments or clicking on unsafe links.
- Malware: Malware is harmful software that is designed to steal data, disrupt operations, or access systems without authorization.
What is the general road map for cyber security?
To start a cyber security career, you need to know:
- Networking Essentials:Understand core networking concepts like IP addresses, protocols (TCP/IP), and network topology(wired & wireless).
- Operating Systems (OS) Fundamentals:Understand popular operating systems like Windows and Linux. Learn about user accounts, file permissions, and basic administration tasks.
- Cyber security Concepts:Familiarize yourself with fundamental cyber security concepts like common cyber threats (phishing, malware, and social engineering) and basic security principles (least privilege, defense in depth).
- Web Application Security:Understand topics like SQL injection, cross-site scripting (XSS), and secure coding practices.
- Cryptography:Gain basic knowledge of cryptography concepts like encryption, hashing, and digital signatures.
Conclusion
Cyber security is a very important topic. You must be updated on it, and we will talk about it in future articles.
