By adding an extra tag, an attacker can confuse the switch and cause it to forward the frame to another VLAN, providing unauthorized access to that VLAN's traffic. + +## Preventing VLAN Hopping + +To secure your network from VLAN hopping attacks, consider implementing the following best practices: + +- **Disable Unused Ports:** Shut down any unused ports on your switches and configure them as access ports instead of trunk ports. This will limit the opportunity for an attacker to establish a trunk link. + +- **Configure Allowed VLANs on Trunk Links:** Restrict the VLANs that can be carried on trunk links by explicitly specifying the allowed VLANs. This will prevent an attacker from accessing unauthorized VLANs through a trunk link. + +- **Implement VLAN Access Control Lists (VACLs):** VACLs can be used to filter traffic at the VLAN level, preventing unauthorized traffic from entering or leaving a VLAN. + +- **Enable 802.1Q Native VLAN Tagging:** By enabling native VLAN tagging and assigning a unique, unused VLAN ID as the native VLAN, you can prevent double tagging attacks. + +Remember that implementing these security practices is crucial in protecting your network from VLAN hopping and other types of network-based attacks. Always stay vigilant and keep your network's security protocols up-to-date to minimize the chances of a successful cyber attack. \ No newline at end of file diff --git a/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/common-network-based-attacks/108-rogue-access-point.md b/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/common-network-based-attacks/108-rogue-access-point.md index dff04484e..b97170c51 100644 --- a/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/common-network-based-attacks/108-rogue-access-point.md +++ b/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/common-network-based-attacks/108-rogue-access-point.md @@ -1 +1,29 @@ -# Rogue access point \ No newline at end of file +# Rogue Access Point + +A **Rogue Access Point (RAP)** is an unauthorized wireless access point that is installed or connected to a network without the network administrator's consent.

This protocol is particularly important in cyber security as it helps us understand the devices on a network, and can sometimes be exploited by attackers to perform various network level attacks. + +## How ARP Works + +In a typical network, devices communicate using their IP addresses. However, the actual communication between devices is facilitated by their MAC (Media Access Control) addresses. ARP is responsible for resolving IP addresses to MAC addresses. Here's a simple example to help illustrate this process: +- Device A wants to communicate with Device B. +- Device A knows Device B's IP address but not its MAC address. +- Device A broadcasts an ARP request on the network, asking "Who has this IP address? Please tell me your MAC address." +- When Device B receives the request and recognizes its own IP address, it sends an ARP reply to Device A, containing its MAC address. +- Device A can now use the MAC address to communicate directly with Device B. + +## Security Concerns + +While ARP is essential to the proper functioning of a network, it also introduces certain security risks. The primary reason for this vulnerability is that ARP is trust-based and does not have built-in authentication. This creates an opportunity for attackers to exploit the system using techniques such as: + +## ARP Spoofing/Poisoning + +ARP spoofing is an attack in which an attacker sends fake ARP messages to a network, causing the devices to associate the attacker's MAC address with an IP address that legitimately belongs to another device. This allows the attacker to intercept, modify, or manipulate the traffic between the target devices, potentially resulting in a man-in-the-middle (MITM) attack or denial of service (DoS). + +## ARP Cache Poisoning + +Similar to ARP spoofing, ARP cache poisoning is the process of injecting dishonest entries into an ARP cache. This can cause devices to send sensitive information to unintended recipients or facilitate attacks like MITM or DoS. + +## ARP in Incident Response and Discovery Tools + +To counter ARP-based attacks and ensure secure communication within a network, various incident response and discovery tools can be utilized, some of which include: + +- **ARP monitoring tools**: These tools monitor ARP activity to detect potential anomalies, such as multiple ARP replies from a single IP address, which could signify an ARP spoofing attack. +- **Static ARP entries**: Configuring static ARP entries on a device eliminates the need for dynamic ARP resolution and minimizes the risk of ARP cache poisoning. +- **Network traffic analyzers**: Network traffic analysis tools, like Wireshark, can help spot suspicious ARP activity and reveal inconsistencies in ARP messages. +- **Intrusion Detection Systems (IDSs)**: These systems monitor network traffic for spotting potential security threats, including ARP-based attacks. + +In conclusion, understanding the ARP protocol and its potential security risks is crucial for maintaining a secure network environment. By utilizing incident response and discovery tools, it is possible to detect, prevent, and mitigate ARP-based attacks, ensuring a safer network for all connected devices. \ No newline at end of file diff --git a/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/incident-response-and-discovery-tools/109-cat.md b/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/incident-response-and-discovery-tools/109-cat.md index 3b1eb18e1..8e10768a2 100644 --- a/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/incident-response-and-discovery-tools/109-cat.md +++ b/src/data/roadmaps/cyber-security/content/103-security-skills-and-knowledge/incident-response-and-discovery-tools/109-cat.md @@ -1 +1,51 @@ -# Cat \ No newline at end of file +# cat + +`cat` is a widely used command-line utility in UNIX and UNIX-like systems.
