#网络安全术语

本文探讨了信息系统安全中的关键概念——攻击介质，它指明了威胁进入系统并造成破坏的具体途径。作者澄清了vector在此并非传统意义上的向量，而是特指攻击的手段或情境。

攻击介质，是指可以攻击信息系统，破坏其安全性的特定路径、方法或是情景。

vector 此处并不是向量的意思。

Chaos Testing(混沌测试)中的攻击向量(Attack Vector)

Chaos Testing (混沌测试)中的攻击向量(Attack Vector)是开发人员/测试人员可以在外部或系统内部触发故障以暴露潜在弱点的一种手段。攻击向量使开发人员/测试人员能够模拟潜在的故障，以了解在不利的动荡条件下的应用程序行为。 在混沌测试（Chaos Testing）中，攻击向量通常不是实际的攻击手段，而是指模拟真实世界中可能出现的故障、异常或不稳定性的场景。

攻击向量（Attack Vector）是一种路径或手段，黑客可以通过它访问计算机或网络服务器，以传递有效负载或恶意结果。攻击向量使黑客能够利用系统漏洞，包括人为因素。 攻击向量包括病毒、电子邮件附件、网页、弹出窗口、即时消息、聊天室和欺骗。所有这些方法都涉及到软件（少数情况下涉及到硬件）和欺骗。在欺骗中，人类操作员通常被愚弄去移除或削弱系统的防御。 ...

Vulnerability Descriptioncommon.up Cross-site Scripting (XSS) refers to client-side code injection attack wherein an attacker can execute malicious scripts into a legitimate website or web application. XSS occurs when a web application makes use of unvalidated or unencoded user input within the output it generates. Discovered by /Scripts/PerFile/XSS_in_URI_File.script The impact of this vulnerabilitycommon.up Malicious JavaScript has access to all the same objects as the rest of the web page, including access to cookies and local storage, which are often used to store session tokens. If an attacker can obtain a user's session cookie, they can then impersonate that user. Furthermore, JavaScript can read and make arbitrary modifications to the contents of a page being displayed to a user. Therefore, XSS in conjunction with some clever social engineering opens up a lot of possibilities for an attacker.

好的，下个部分，Experimental setup To perform the attacks, we set up our test-bed setup. We created a generic attack vector dataset that can be easily expanded. Our dataset is created using different devices as shown in 2. For WPA3 enabled access point, we used the Linksys E8450 device (WiFi 6), and for the WPA3 WiFi adapter, D-link DWA-X1850 (WPA 3) was used. One Alfa AWUS036NHA adapter (Atheros AR9271 chipset) was used to monitor the channel and inject packets to perform attacks. Netgear A6210 device is used for monitoring traffic between AP and STAs. Netgear device was connected to a desktop running Ubuntu 20.04. For STAs, we have used a Samsung A7 tablet, MacBook Air, and an HP laptop running windows 10 using a D-link adapter supporting WPA3. We used Linksys AP, which supports IEEE 802.11ax and runs in WPA3 mode on a 2.4 GHz frequency. All our at tacks are performed on 2.4 GHz frequency only. The 5GHz frequency was also working, but no attacks were performed on the 5GHz frequency. The Netgear A6210 adapter was used for the purpose of capturing packets. Figure 2 is just a representation of our setup for testing and collecting data. Initially, we assumed that the WPA3 connection mandates the usage of MFP. However, in our experiment, we have found that when AP and STA are both WPA3 compatible, we were able to de-authenticate the client simply by flooding de auth frames. We have performed all our experiments without manually switching on the MFP. This was done to examine if MFP is used automatically or not. To create the dataset, we had to label each frame if it was responsible for a particular attack. This initial detection model is based on traffic analysis of specific frames. The mechanism is primarily based on the following frames: 1) Beacon Frame 2) Authentication Frame 3) De-authentication Frame 4) Association Frame 5) Dis-association Frame 6) EAPOL Frame The resulting dataset was a collection of packet captures constructed from multiple attack sessions with a total of 250 attributes. The attacks considered in this research are De authentication, Rogue AP, Beacon Flooding, Evil Twin, and Krack attacks. The dataset has CSV files that contain the packets transmitted in the network while the attacks were being performed. These packets can be analyzed using a deterministic algorithm (as shown in Section III) to detect the attacks and also using ML to find a correlation between the attributes to detect the attacks. To the best of our knowledge, this is the first dataset of WPA3 attacks that have been created out of real-life intrusion experiments on a test bed.

An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting a specific flow of the sftunnel communication between an FMC device and an FTD device. A successful exploit could allow the attacker to decrypt and modify the sftunnel communication between FMC and FTD devices, allowing the attacker to modify configuration data sent from an FMC device to an FTD device or alert data sent from an FTD device to an FMC device. v3.1 v4.0 Base 8.1 CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H 7.7 CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N Base + Threat 5.2 CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U CVSS v4 Score: Base + Threat 5.2 Metric Value Comments Attack Vector Network The vulnerable system is accessible from remote networks.
