Nmap memo form: From Discovery to vulnerability exploitation (Part 4) What is a firewall?A firewall is software or hardware used to control network access. There are two types: 1. Host-Based firewall; 2. Network-based firewall.Host-Based FirewallThis software runs on a single host to control inbound traffic (from network to host) and outbound traffic (from host to network ). These software are installed on

Nmap memo form: From Discovery to vulnerability exploitation (Part 5) This is the last part of the memo list. Here we will mainly discuss vulnerability assessment and penetration testing.Database Audit list database names nmap-sV--script=mysql-databases192.168.195.130 The database list is not displayed because the user name and password are empty.

From http://nmap.orgHost discovery Host discovery is also called Ping scanning, but it is far more than sending simple ICMP echo request packets using a widely known ping tool. You can use list scan (-sL) Or by disabling Ping (-P0) Skip the ping step. You can also use multiple ports to combine tpc syn/ack, UDP, and ICMP. These probes aim to get a response to show whether an IP address is active (Host or ne

Using Network Service Discovery, showed you how to discover services that are connected to a local network. however, using Wi-Fi Direct trad; Service Discovery allows you to discover the services of nearby devices directly, without being connected to a network. you can also advertise the services running on your devic

The latest common network tools in CentOS: nmap for batch host service Scanning In Linux, there are many powerful network scanning tools, including host scanning, host service scanning, and route scanning. You have previously written common host scanning and routing scanning tools. nmap supports batch host scanning and

Linux has a lot of powerful network scanning tools, network scanning tools can be divided into: host scanning, host service scanning, route scanning and so on.Prior to the usual host scan and route scanning tools, NMAP supports bulk host scanning and host service scanning.Installation of Nmap directly using: Yum instal

Service Discovery With the increasing popularity of micro-services, after the system split, the various service modules between the provider and consumer need to be able to find each other, we call service discovery. In soa/distributed systems, services need to find each ot

Specific requirements:1. Due to the independent development of xmzoomeye-agent currently passive monitoring mainly, in order to achieve Zabbix low-level discovery service independent discovery, need to automatically obtain the occupied port list according to the process name, and report data according to the port analysisImplementation ideas:1. Use the Psutil mod

The previous article explains Springcloud components and concepts, and then explains the use, principle, and role of each component of the Springcloud component, which mainly provides modules including: service Discovery (Eureka), Circuit breaker (Hystrix), Smart Path (Zuul), Client load balancer (Ribbon), Archaius,turbine etc today, Eureka is the registryA: Eureka IntroductionEureka is a sub-module of spri

First, how to solve the hard coding problem Last lesson we learned about the service provider and service providers, one of the very big problem is hard coding problem, it is well known that in the Internet development, the IP and port number of access address is dynamic, a service is stopped and re-enabled after the IP and port may have changed, so hard coding i

submit a code, found and others submitted conflict, so because you are submitted after the person, you have the responsibility to merge code, finally merge successful, and so on again, when the discovery conflict, you are not very annoyed. The greater the team size, the greater the probability of conflict. So should be split into different modules, every 10 people around the maintenance of a module, that is, a project, the first code conflict probabi
