网络攻击测试方法和工具简介 目录 网络攻击测试方法和工具简介 1 说明 1 漏洞检测 1 扫描系统漏洞 2 网络攻击检测和防护 3 攻击模拟 3 攻击防护 5 说明 本文档内容根据网络上关于网络攻击测试方法和工具进行了分类整理,归纳出最适用于漏洞检测和 DDOS 攻防测试工具。本文中出现的工具大部分属于开源和可以免费获取到的网络工具。 漏洞检测 目前针对漏洞检测的工具分为两大类: 网络安全公司开发的收费软件 开源爱好者和组织开发的免费软件 一般收费软件更新速度快,能够根据漏洞数据库扫描出最新的漏洞;而免费工具基本很少更新,基本上只能扫描到一些基本的漏洞。 著名收费漏洞扫描软件,国内有:绿盟,知道创宇,360,软件均无法免费获得,需购买。 著名收费漏洞扫描软件,国外:Nessus,OpenVAS, Core Impact。 免费漏洞扫描软件:国内无,国外有 nmap, Retina, Nipper。 经测试使用,nmap 数据库比较新,能够实用。 扫描系统漏洞 以普通 Linux 系统为例: 从官网下载最新 nmap 7 源代码, https://nmap.org/download.html . 解压源代码到本机 bzip2 -cd nmap- .tar.bz2 | tar xvf – 进入源码目录 cd nmap- 配置源码 ./configure 配置完成成功后,会有 ASCII

Getting error when my python ddos script running

问题 I am trying to attack my server and I have this little ddos python script for that. But unfortunately I got this error: ip = socket.gethostbyname(host) socket.gaierror: [Errno 11004] getaddrinfo failed Any idea how to solve this problem? And this is the script: import time, socket, os, sys, string def restart_program(): python = sys.executable os.execl(python, python, * sys.argv) curdir = os.getcwd() print ("DDoS mode loaded") host="http://hajnalgroup.com" port="80" message="+----------------

什么是DDOS攻击

ddos攻击已经成为站长们皆知一种网络攻击方式。现在随着网络的发展,网络攻击越来越多,而ddos攻击则也是频繁的出现在我们的视野中。而且,针对ddos攻击的防御部署工作也是讨论的热点话题。毕竟随着互联网络带宽的增多和多种ddos攻击黑客工具的不断发布,使其ddos攻击越来越不受控制。 那么ddos是怎么攻击计算机或网络的?ddos攻击可使计算机或网络无法提供正常的服务,DDOS是DOS攻击中的一种方法。将多个计算机联合起来作为攻击平台,对一个或多个目标发动DDoS攻击,从而成倍地提高拒绝服务攻击的威力。 DDoS(Distributed Denial of Service,分布式拒绝服务) 定义: 主要通过大量合法的请求占用大量网络资源,从而使合法用户无法得到服务的响应,是目前最强大、最难防御的攻击之一。 一、什么是DDOS攻击? DDoS也就是分布式拒绝服务攻击。它使用与普通的拒绝服务攻击同样的方法,但是发起攻击的源是多个。通常攻击者使用下载的工具渗透无保护的主机,当获得该主机的适当的访问权限后,攻击者在主机中安装软件的服务或进程(以下简侈怔理)。这些代理保持睡眠状态,直到从它们的主控端得到指令,对指定的目标发起拒绝服务攻击。 ——————————————— 实际上,DOS的攻击方式有很多种,接下来介绍几种比较常见的攻击途径: 1、IP欺骗DOS攻击 这种攻击利用RST位来实现

What happens if a DDOS attack hits Windows Azure Web Sites? [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I am just thinking of moving a website from a VPS to Windows Azure Web Sites. After doing a load test, I accidentally took down my test website, using around 30MB over the daily bandwidth. This made me wonder what would happen if my website was suddenly hit by a DDOS attack? I'm pretty sure everything would max

Microsoft Azure DDOS protection

问题 I am running an enterprise scale application in Microsoft Azure. I wanted to know what the recommendations are for DDOS projection in Microsoft Azure. The documentation clearly states that the platform is protected from DDOS with not much more detail. My understanding of the Azure DDOS is If another customer is being attacked by a DDOS attack, your application won't suffer If your application is being attached by a DDOS attack, Microsoft will stop all connections to your end point and in

如何防止DDos攻击?

---恢复内容开始--- 一、拒绝服务攻击的发展   从拒绝服务攻击诞生到现在已经有了很多的发展,从最初的简单Dos到现在的DDOS。那么什么是Dos和DDOS呢?DoS是一种利用单台计算机的攻击方式。而DDOS(Distributed Denial of Service,分布式拒绝服务)是一种基于DoS的特殊形式的拒绝服务攻击,是一种分布、协作的大规模攻击方式,主要瞄准比较大的站点,比如一些商业公司、搜索引擎和政府部门的站点。DDOS攻击是利用一批受控制的机器向一台机器发起攻击,这样来势迅猛的攻击令人难以防备,因此具有较大的破坏性。如果说以前网络管理员对抗Dos可以采取过滤IP地址方法的话,那么面对当前DDOS众多伪造出来的地址则显得没有办法。所以说防范DDOS攻击变得更加困难,如何采取措施有效的应对呢?下面我们从两个方面进行介绍。   二、预防为主保证安全   DDOS攻击是黑客最常用的攻击手段,下面列出了对付它的一些常规方法。  (1)定期扫描   要定期扫描现有的网络主节点,清查可能存在的安全漏洞,对新出现的漏洞及时进行清理。骨干节点的计算机因为具有较高的带宽,是黑客利用的最佳位置,因此对这些主机本身加强主机安全是非常重要的。而且连接到网络主节点的都是服务器级别的计算机,所以定期扫描漏洞就变得更加重要了。  (2)在骨干节点配置防火墙

Can one cache and secure a REST API with Cloudflare?

孤者浪人 提交于 2019-12-20 09:28:50
问题 I am designing a RESTful API that is intended to be consumed by a single-page application and a native mobile app. Some calls of this API return public results that can be cached for a certain time. Moreover, there is a need for rate protection to protect the API against unauthorized users (spiders) Can I use Cloudflare to implement caching and rate-limiting / DDOS protection for my RESTful API? Caching: Cloudflare supports HTTP cache control headers so the API can decide for each entity

问题 Since few hours, I'm having multiple requests coming from various IP's to our website occuring every second(maybe 4 or 5 requests per second). The website's usual traffic is about 3 to 5 requests per minute. The requests are very random, for example: /gtalczp/197zbcylgxpoaj-26228e-dtmlnaibx/ /109/jxwhezsivr/10445_xwvpfdyzhea.cgi /nouyaku.html /index.php/43e3133-pmuwbfgoedakvxs/ /keyword_list/s_index=L The site's indexing in google is now all in japanese characters and messed up.
