IPS (Intrusion Prevention System): An IPS is a security solution that actively monitors network traffic to detect and block any malicious activities or unauthorized access attempts. It works by analyzing network packets and comparing them against a set of predefined rules or signatures to identify potential threats.

IDS (Intrusion Detection System): Similar to an IPS, an IDS also monitors network traffic but instead of actively blocking threats, it alerts system administrators or security personnel about potential security breaches or suspicious activities on the network. The alerts generated by an IDS can help in investigating and responding to security incidents.

Nmap: Nmap is a powerful network scanning and mapping tool used for network exploration and security auditing. It allows scanning and identifying open ports, services running on those ports, and details about the operating systems of the target hosts. Nmap is widely used by both network administrators and attackers for reconnaissance purposes.

Reconnaissance: Reconnaissance is the process of gathering information about a target network or system to identify potential vulnerabilities and weaknesses. It involves gathering publicly available information, such as DNS records, network configurations, and employee information, to gain an understanding of the target's infrastructure and security posture. Reconnaissance is an essential step in the hacking process.

Footprinting: Footprinting is a part of the reconnaissance process that involves gathering information about a target network or organization using various techniques and sources. This information can include details about network infrastructure, operating systems, organization hierarchy, key personnel, and third-party relationships. Footprinting helps attackers identify potential entry points and vulnerabilities to plan further attacks.

Wireshark Basics: Wireshark is a popular open-source packet analysis tool used for network troubleshooting, analysis, and security auditing. It captures and analyzes network traffic at a microscopic level, allowing users to examine packets, monitor network performance, and detect any anomalies or security incidents.

Bash Scripting: Bash scripting refers to writing and executing scripts using the bash (Bourne Again Shell) command-line interpreter in Unix-like operating systems. Bash scripts automate repetitive tasks, such as file manipulations, system administration, and network operations, by combining multiple commands and control structures within a script.

Firewall Operations & SIEM: Firewalls are network security devices that filter and control incoming and outgoing network traffic based on predetermined security rules. They act as a barrier between a trusted internal network and untrusted external networks, effectively blocking unauthorized access and protecting against various threats. SIEM (Security Information and Event Management) is a centralized security solution that combines security event management, log management, and real-time analysis of security alerts from various sources. It helps organizations identify and respond to security incidents by providing a comprehensive view of their security posture.

SOC-as-a-Service: SOC (Security Operations Center) as a Service is a managed security service provided by third-party vendors to help organizations establish and maintain a proactive security monitoring and incident response capability. It typically includes 24/7 monitoring, threat intelligence, log analysis, incident investigation, and response services to protect against evolving cyber threats.

Snort IPS: Snort is an open-source Intrusion Prevention System (IPS) that detects and prevents network-based attacks, such as malware infections, DoS (Denial of Service) attacks, and unauthorized access attempts. Snort analyzes network traffic in real-time, comparing it against a set of rules or signatures to identify and block potential threats. It is highly customizable and widely used for network security monitoring.
