VLANs logically segment networks based on functions or project teams, regardless of physical connections. VLANs create broadcast domains by assigning switch ports to VLANs. Routers are used for communication between VLANs. Common VLAN types include port-based VLANs where a device assumes the VLAN of its connected port, and dynamic VLANs where software assigns VLANs based on MAC addresses. VLAN tagging allows a link to carry multiple VLANs by adding a tag to frames to designate VLAN membership.
This document discusses configuring inter-VLAN routing between VLANs on a converged network. It outlines objectives to explain how network traffic is routed between VLANs using different routing options, configure inter-VLAN routing on a router, and troubleshoot common connectivity issues. The summary explains that inter-VLAN routing requires a router or layer 3 switch to route between VLANs, and discusses traditional routing using multiple router interfaces per VLAN versus a "router on a stick" topology using subinterfaces on a single router interface connected to a layer 2 switch.
VLANs logically group users and resources together without being restricted by physical network segments. There are static and dynamic VLANs, with static VLAN port assignments always remaining fixed while dynamic VLANs are created through management software. Frame tagging allows VLANs to span multiple switches by uniquely assigning a VLAN ID to each frame. The VLAN Trunking Protocol (VTP) manages VLAN configurations across switches to provide benefits like consistent VLAN setup, accurate monitoring, and dynamic reporting of new VLANs. Configuring VLANs involves creating VLANs, assigning switch ports, configuring trunk ports between switches, and setting up inter-VLAN routing using subinterfaces on a router interface.
Virtual LANs (VLANs) logically segment a network to increase performance and security. VLANs can be static or dynamic and identify devices using frame tagging. VLAN trunking protocol (VTP) manages VLAN configurations across switches and has different modes like server, client, and transparent. VLANs are configured by creating them, assigning ports, setting up trunks, and configuring inter-VLAN routing. Troubleshooting involves checking the VTP status to ensure all switches are in the same domain and have the correct configuration revision.
This document discusses inter-VLAN routing and two common methods: using a router on a stick configuration or an internal router within a multilayer switch. With a router on a stick, subinterfaces are used to separate VLANs on the router and 802.1Q trunking passes traffic between VLANs. Alternatively, some switches have an internal router module that can perform inter-VLAN routing without subinterfaces by configuring VLAN routing and trunking interfaces. The document provides examples of configuring both approaches and discusses their application in campus network designs.
Router-on-a-stick is a method of inter-VLAN routing where a single router interface acts as a trunk link to a switch. This interface is divided into multiple logical subinterfaces, each tied to a VLAN and assigned an IP address. When a host in one VLAN sends traffic to a different VLAN, the switch tags it with the VLAN ID. The router routes the traffic to the correct subinterface and VLAN based on the IP addresses and switch port VLAN configurations. This allows a router to interconnect multiple VLANs using only one physical interface, reducing hardware costs compared to using one interface per VLAN.

The document outlines several examples of SQL injection attacks, such as unauthorized access, database modification, and denial of service. It discusses techniques for finding and exploiting SQL injection vulnerabilities. Finally, it recommends effective mitigation strategies like prepared statements and input whitelisting to protect against SQL injection attacks.
- Cross-site scripting (XSS) occurs when malicious scripts are executed in a user's browser from a vulnerable web application. This allows attackers to steal authentication cookies and sensitive information or take actions on the user's behalf.
- The same-origin policy is intended to isolate scripts and resources from different origins to prevent unauthorized access, but it has limitations that can be exploited in XSS attacks.
- Cross-site request forgery (CSRF or XSRF) is an attack where unauthorized commands are transmitted from a user who is currently authenticated to a target site, such as making payments on a banking site the user has logged into. This is possible because browsers include cookies in all requests to the originating

This document discusses the history and concepts of cryptography. It begins with classical cryptography and how encryption has evolved with computers to become more complex. It then covers specific ciphers like the Enigma machine and how the British broke German codes during WWII. The document discusses the development of modern ciphers like DES and AES, how public key cryptography works using RSA, and concepts of symmetric and asymmetric encryption. It provides details on block ciphers and the design of ciphers like DES.
The document discusses classical cryptography and symmetric encryption. It covers the following key points:
1) Symmetric encryption uses a shared secret key between the sender and receiver to encrypt and decrypt messages. It was the only type of encryption prior to public-key cryptography being invented in the 1970s.
2) The basic components of cryptography are plaintext, ciphertext, encryption/decryption algorithms, and keys. Cryptanalysis is the study of decrypting ciphertext without knowing the key.
3) For secure symmetric encryption, a strong algorithm and a secret key only known to the sender and receiver are required.
4) Classical ciphers include the Caesar cipher which shifts letters and monoalphabetic ciphers which map each plaintext
Chapter 6 information hiding (steganography)newbie2019
The document discusses information hiding techniques for secure communication, specifically focusing on steganography. It defines steganography as hiding information in an unremarkable carrier such as images, video, or audio in a way that prevents detection. The document outlines some goals and applications of steganography, describes some historical steganography techniques, and discusses how modern digital steganography can hide information in the least significant bits of files' color values. It also distinguishes steganography from cryptography and watermarking.
This document provides an overview of network security concepts. It begins by stating the goals of network security are to protect confidentiality, maintain integrity, and ensure availability. It then discusses common network security vulnerabilities and threats that can arise from misconfigured hardware/software, poor network design, inherent technology weaknesses, end-user carelessness, or intentional end-user acts. The document also covers the need for network security due to increased connectivity from closed to open networks and differentiates between open versus closed security models. It emphasizes striking a balance between security and user productivity.
Chapter 4 vulnerability threat and attack newbie2019
This document discusses threats, vulnerabilities, and attacks related to information security. It defines threats as potential dangers that could breach security, and lists categories of threats like deliberate threats, environmental threats, and accidental threats. Vulnerabilities are weaknesses that can be exploited by threats, like physical vulnerabilities, hardware/software vulnerabilities, and human vulnerabilities. Attacks are exploits of vulnerabilities that damage systems. Common attacks are discussed like passive attacks that obtain information and active attacks that alter systems. The document also categorizes attacks as interruptions, interceptions, modifications, or fabrications of systems and assets. The three biggest common attacks are said to be virus, worm, and Trojan horse attacks.
The document discusses authentication, authorization, and accounting (the three As) as a leading model for access control. It describes authentication as identifying users, usually with a username and password. Authorization gives users access to resources based on their identity. Accounting (also called auditing) tracks user activity like time spent and services accessed. The document provides details on different authentication methods like passwords, PINs, smart cards, and digital certificates. It emphasizes the importance of strong passwords and changing them regularly.
This document discusses several key concepts in information system security:
Authentication involves verifying the identity of a user or system, usually through passwords, ID cards, or biometrics. Authorization determines what resources a user can access after authentication. Privacy/confidentiality ensures sensitive personal data and messages are kept secret through encryption. Integrity keeps information from being altered without authorization. Availability ensures security services and data remain accessible. Non-repudiation prevents denied participation in online transactions. Auditing records network activity and communications for security monitoring through system logging.
This document discusses information system security. It defines information system security as collecting activities to protect information systems and stored data. It outlines four components of an IT security policy framework: policies, standards, procedures, and guidelines. It also discusses vulnerabilities, threats, attacks, and trends in attacks. Vulnerabilities refer to weaknesses, while threats use tools and scripts to launch attacks like reconnaissance, access, denial of service, and viruses/Trojans. Common attacks trends include malware, phishing, ransomware, denial of service, man-in-the-middle, cryptojacking, SQL injection, and zero-day exploits.
