What are the 3 major types of cyber security?
Cybersecurity refers to the practices and technologies used to protect computer systems, networks, and data from unauthorized access, theft, or damage. There are many different types of cybersecurity, but they can be broadly categorized into three major types: network security, endpoint security, and application security.
Network security refers to the protection of computer networks and the data they contain from unauthorized access, theft, or damage. This type of cybersecurity focuses on the security of the network itself, including the hardware, software, and protocols used to connect and communicate between devices.
Network security includes measures such as firewalls, intrusion detection systems (IDS), and virtual private networks (VPNs). These technologies help to protect the network from external threats, such as hackers and malware, and can also prevent unauthorized access to the network by employees or other insiders.
Firewalls are the first line of defense in network security. They monitor incoming and outgoing network traffic and block any traffic that does not meet predefined security rules. Intrusion detection systems (IDS) monitor the network for suspicious activity and alert administrators to potential security breaches. Virtual private networks (VPNs) provide a secure connection between remote users and the network, allowing users to access network resources from anywhere while maintaining security.
Endpoint security refers to the protection of individual devices, such as laptops, desktops, and mobile devices, from cyber threats. This type of cybersecurity focuses on securing the device itself, as well as the data it contains and the applications it runs.
Endpoint security includes measures such as antivirus software, intrusion prevention systems (IPS), and encryption. Antivirus software scans the device for viruses and other malware and removes them if found. Intrusion prevention systems (IPS) monitor the device for suspicious activity and block any activity that could indicate a security breach. Encryption protects data stored on the device and transmitted over the network, making it unreadable to anyone who does not have the key to decrypt it.
Application security refers to the protection of software applications from cyber threats. This type of cybersecurity focuses on securing the code and data used by the application, as well as the data it processes and stores.
Application security includes measures such as secure coding practices, vulnerability testing, and access controls. Secure coding practices involve writing code that is free from vulnerabilities, such as buffer overflows and SQL injection attacks. Vulnerability testing involves scanning the application for vulnerabilities and identifying ways to fix them. Access controls limit the access that users have to the application, ensuring that only authorized users can access sensitive data or perform sensitive actions.
In conclusion, network security, endpoint security, and application security are the three major types of cybersecurity. Network security focuses on protecting the network itself, while endpoint security focuses on protecting individual devices. Application security focuses on protecting software applications from cyber threats. All three types of cybersecurity are essential for protecting computer systems, networks, and data from unauthorized access, theft, or damage. By implementing these cybersecurity measures, organizations can minimize their risk of cyber attacks and protect their assets from cyber criminals.
