Bullet Points:
To provide a better understanding of the topics covered, we have included some sample bullet points for each section.
- Network Security
Network security is the practice of protecting networks from unauthorized access or attacks.
The essential elements of network security are confidentiality, integrity, and availability.
A firewall is a network security device that monitors and controls incoming and outgoing traffic based on predetermined security rules.
An intrusion detection system (IDS) is a device or software application that monitors network traffic for signs of malicious activity.
A virtual private network (VPN) is a secure and encrypted connection that allows users to access a private network over the internet.
A distributed denial-of-service (DDoS) attack is a type of attack that aims to disrupt the normal functioning of a website or network by overwhelming it with traffic.
A man-in-the-middle (MITM) attack is a type of attack where an attacker intercepts communication between two parties to steal information or compromise the network.2. System Security
System security refers to the practice of protecting individual computer systems from unauthorized access or attacks.
An access control list (ACL) is a list of permissions that determines which users or systems have access to specific resources.
A biometric authentication system uses biometric data, such as fingerprints or facial recognition, to authenticate users.
Symmetric encryption uses the same key to encrypt and decrypt data, while asymmetric encryption uses different keys.
A security information and event management (SIEM) system is a tool that collects and analyzes security-related data from multiple sources.
A honeypot is a decoy system that is designed to attract attackers and detect or deflect their attacks.
A rootkit is a type of malware that can hide its presence on a system and provide an attacker with unauthorized access.
3. Ethical Hacking
Ethical hacking is the practice of using hacking techniques for legitimate purposes, such as testing the security of a system.
Penetration testing is the process of simulating an attack to identify vulnerabilities and weaknesses in a system, while vulnerability scanning is the process of identifying potential vulnerabilities without attempting to exploit them.
A SQL injection attack is a type of attack that exploits vulnerabilities in SQL databases to gain unauthorized access to data.
A phishing attack is a type of attack where an attacker masquerades as a trustworthy entity to trick a victim into providing sensitive information.
A cross-site scripting (XSS) attack is a type of attack that injects malicious code into a website to steal information or compromise the site.
A social engineering attack is a type of attack that uses psychological manipulation to trick a victim into divulging sensitive information.
A buffer overflow attack is a type of attack that exploits a vulnerability in a program’s buffer to execute malicious code.
4. Web Application Security
Web application security refers to the practice of protecting web applications from unauthorized access or attacks.
A cross-site request forgery (CSRF) attack is a type of attack that tricks a user into performing an unintended action on a website.
A file inclusion vulnerability is a type of vulnerability that allows an attacker to include and execute files from a remote server.
A broken authentication and session management vulnerability is a type of vulnerability that allows an attacker to hijack a user’s session or gain unauthorized access to a system.
A command injection attack is a type of attack that executes malicious commands on a system by injecting them into a vulnerable application.
