Cybersecurity For Beginners
Cybersecurity for Beginners: How to Get Started in this Field
Cybersecurity is the field of protecting networks, devices, and data from unauthorized access, damage, or attack. Cybersecurity is vital for anyone who uses the internet, whether for personal or professional purposes. Cybersecurity can help you prevent identity theft, data breaches, ransomware, phishing, and other cyber threats that can compromise your privacy, security, and reputation.
Cybersecurity for Beginners
In this article, we will introduce you to some of the basics of cybersecurity for beginners, such as the CIA triad, the specialties in cybersecurity, and the common types of attacks. We will also give you some tips on how to learn cybersecurity and pursue a career in this field.
What is the CIA Triad?
The CIA triad is a model that defines the three main objectives of cybersecurity: confidentiality, integrity, and availability. These objectives are also known as the security principles or the security goals.
Confidentiality means that only authorized parties can access sensitive information and functions. For example, military secrets, medical records, and personal data should be kept confidential from unauthorized users.
Integrity means that only authorized parties can modify, add, or delete sensitive information and functions. For example, financial transactions, academic records, and software updates should be protected from unauthorized changes.
Availability means that systems, functions, and data must be accessible and usable by authorized parties when needed. For example, websites, email servers, and online services should be available and reliable for legitimate users.
The CIA triad helps cybersecurity professionals design and implement security measures that can protect information and systems from various threats. For instance, encryption can help achieve confidentiality by making data unreadable to unauthorized parties. Authentication can help achieve integrity by verifying the identity of users and devices. Backup can help achieve availability by restoring data in case of loss or damage.
What are the Specialties in Cybersecurity?
Cybersecurity is a broad and diverse field that encompasses many domains and disciplines. Depending on your interests and skills, you can choose to specialize in one or more areas of cybersecurity. Some of the common specialties in cybersecurity are:
Security engineering involves designing and building secure systems and networks that can resist attacks and recover from incidents.
Security analysis involves monitoring and assessing systems and networks for vulnerabilities and anomalies that can indicate potential or ongoing attacks.
Security incident response involves investigating and responding to security breaches and incidents that can compromise systems and data.
Security auditing involves evaluating and testing systems and networks for compliance with security standards and regulations.
Security management involves planning and implementing security policies and strategies that can align with organizational goals and objectives.
Security education involves teaching and training users and employees on security awareness and best practices.
To pursue a career in cybersecurity, you will need to acquire relevant knowledge and skills in various topics, such as computer networking, operating systems, programming languages, cryptography, cloud computing, cyberattacks, risk management, etc. You will also need to obtain certifications that can validate your expertise and credibility in the field.
What are the Common Types of Attacks?
Cyberattacks are malicious actions that aim to exploit vulnerabilities in systems and networks to cause harm or gain unauthorized access. Cyberattacks can have different motives and methods depending on the attackers' goals and capabilities. Some of the common types of attacks are:
Ransomware is a type of malware that encrypts data or locks systems until a ransom is paid by the victims. For example, WannaCry ransomware infected millions of computers worldwide in 2017.
Phishing is a type of social engineering that tricks users into clicking malicious links or attachments that can steal their credentials or infect their devices. For example, phishing emails can impersonate legitimate organizations or individuals to lure users into revealing their passwords or bank details.
Distributed denial-of-service (DDoS) is a type of attack that floods systems or networks with overwhelming traffic or requests that can disrupt their normal functioning or availability. For example, DDoS attacks can target websites or online services to make them inaccessible to legitimate users.
Data breach is a type of attack that exposes confidential or sensitive information to unauthorized parties. For example, data breaches can affect millions of consumers by exposing their personal data or credit card information.
Password cracking is a type of attack that attempts to guess or break passwords using various techniques such as brute force, dictionary attack, rainbow table attack, etc. For example, password cracking can enable attackers to access protected accounts or systems.
To protect yourself from cyberattacks, you need to follow some basic security practices such as using strong passwords, updating your software regularly, avoiding suspicious links or attachments, backing up your data frequently, using antivirus software etc.
