This document introduces the network analysis tool Wireshark and provides instructions for downloading, installing, and using it. Wireshark is free software that allows users to capture network traffic in real time and view the contents of packets. The document explains what a packet sniffer is and how it works, describing that it passively observes and records network packets without sending any itself. It also provides screenshots and explanations of Wireshark's graphical user interface and how to use various features like filtering packets by protocol.
Snort is an open-source network intrusion detection and prevention system that performs real-time traffic analysis and packet logging on IP networks. It can detect a variety of attacks through protocol analysis, content searching, and matching. Snort functions in sniffer, packet logger, and intrusion detection modes. As a network intrusion detection system, it monitors network traffic and compares it to a database of attack signatures. Snort rules are used to detect suspicious activity and are organized into categories covering web, SQL, shellcode attacks and more.
This document discusses port security features on Cisco switches. Port security allows controlling which source MAC addresses are allowed on a switch port. If an unauthorized MAC address enters a port, the switch can take actions like shutting down the port or discarding traffic from the unauthorized MAC. Port security modes include shutdown, restrict, and protect. Features like secure MAC address aging and sticky MAC learning are also covered. The document provides an overview of port security configuration and commands.
The document discusses upgrading Snort from an intrusion detection system (IDS) to an intrusion prevention system (IPS) to provide active network traffic control. An IDS operates in detection mode only using port mirroring, while an IPS requires original traffic and can actively block threats. The document provides instructions for configuring Snort in inline mode between two network segments using two network cards and iptables rules to redirect traffic. It notes that Snort IPS provides transparent control and flexibility through multiple queues and rule sets when using the NFQ module.
This document summarizes a student's class presentation on the network intrusion prevention and detection system called Snort. It describes what Snort is, its architecture and components, how its detection engine uses rules to detect intrusions, and possible research areas to improve Snort such as developing more efficient detection algorithms or organizing rules into better data structures.

It then discusses why network monitoring is needed and current research progress. The document outlines the system design, including UML diagrams, and tools and protocols used. It provides details on implementation modules like the network browser and traffic monitoring. Finally, it discusses testing and future enhancements.
Configure Cisco Routers for Syslog, NTP, and SSH Operations Kelson Silva
This document provides instructions to configure OSPF MD5 authentication, NTP, syslog logging, and SSH on routers to improve network security. Key steps include configuring OSPF MD5 authentication between routers, configuring routers as NTP clients to synchronize time with authentication, configuring routers to log messages to a syslog server, and configuring one router to accept only SSH connections and generate an RSA key pair for encryption.
In this brief presentation, Chris Gerritz (co-founder and CPO of Infocyte) shares insights on finding and responding to hidden attackers within your network.
Learn about cybersecurity incident response, forensic triage, and the differences between telemetry and protection.
This presentation originally took place at Check Point Software's 2019 CPX 360 conference in Las Vegas.
1) Security audits evaluate the level of information security in an organization across technical, physical, and administrative controls.
2) There are three main types of security audits: external audits conducted by a third party, internal audits done within a company by other units or headquarters, and self-audits conducted by in-house personnel.
3) The objectives of security audits are to assess the adequacy and effectiveness of security measures and management controls through evaluating physical security processes, defining roles and responsibilities, and focusing on high-risk areas.
Snort is an open source network intrusion detection system (IDS) that can perform real-time traffic analysis and packet logging on IP networks. It works by using rules to compare network traffic patterns to known attacks and flag any matches. Snort has four main components - the packet sniffer, preprocessors, detection engine, and output. The sniffer reads packets, preprocessors check for certain behaviors, the detection engine matches rules, and output generates alerts that can be logged or sent to external systems. Snort rules can detect a variety of attacks and are useful for monitoring networks when vulnerabilities are known but patches are not yet available.
Firewalls act as a choke point between networks to control and monitor traffic. Packet filters examine each IP packet to allow or deny services based on rules, while stateful packet filters track client-server sessions to better detect invalid packets. Application proxies have full access to protocols and validate requests before fulfilling them, but cannot support all services. Circuit gateways relay TCP connections between trusted internal users and external networks. Bastion hosts are highly secured systems that may run gateway or service functions with connections to multiple networks. Access control determines what resources users can access based on their identity and the classification of the protected objects.
Dynamic ARP inspection (DAI) is a security feature that prevents man-in-the-middle attacks by validating ARP packets. It relies on DHCP snooping to build a database of valid IP-MAC address bindings. When enabled, DAI will drop ARP packets that do not match entries in the DHCP snooping database, preventing ARP poisoning attacks. The document then demonstrates configuring and testing DAI on a switch to block an ARP poisoning attempt by a rogue workstation.
This document provides an introduction to analyzing network traffic using Wireshark and describes several methods for capturing network traffic when Wireshark is not installed directly on the target system. It discusses using a hub, port mirroring, putting a machine in bridge mode, ARP spoofing, and remote packet capture using rpcapd as ways to capture traffic for analysis in Wireshark without direct access to the target system. Installing Wireshark on another system and using these techniques allows network administrators to analyze network traffic without disrupting systems.

The document compares the security capabilities of an intrusion prevention system (IPS), intrusion detection system (IDS), and web application firewall (WAF). It finds that a WAF provides more comprehensive protection against web application vulnerabilities and attacks than an IPS or IDS, including protection for common threats like SQL injection, cross-site request forgery, and session hijacking. The document also provides specifications for four WAF appliance models with throughput ranging from 100 Mbps to 2 Gbps and storage from 1TB to 2TB.
The document discusses firewalls and iptables firewall configuration on Linux systems. It provides details on firewall types (packet filtering, stateful inspection, proxy-based), configurations (screened host, screened subnet, DMZ), and iptables concepts like tables, chains, rules. It shows examples of iptables commands to implement common firewall rules like accepting loopback traffic and allowing HTTP/HTTPS outbound while blocking all other inbound/outbound traffic. The goal is to provide an overview of firewalls and demonstrate basic Linux firewall configuration using iptables.
The document discusses different types of firewalls including hardware and software firewalls, and describes their purposes and functions. It outlines the history of firewalls from their origins in the late 1980s to prevent unauthorized access. The document also defines various firewall techniques like packet filtering, application gateways, and proxy servers; and types such as stateful inspection firewalls, unified threat management firewalls, and next-generation firewalls.
