Firewall Interfaces

Ferm is a tool for maintaining and installing complex firewall rules. It allows you to reduce the monotonous task of embedding rules and chains, allowing the firewall administrator to spend more time developing good rules and reducing the appropriate implementation time for these rules. These rules will be the preferred kernel interfaces executed, like IPChains and iptables. Firewall rules can also be split into different files and loaded. Ferm 2.1 This version can better support Ipv4/http://www.aliyun.com/zixun/aggregat ...

1. Firewall Technology "Firewall" is a kind of image, in fact it is a combination of computer hardware and software, so that the Internet and the intranet to establish a security gateway (Scurity Gateway), while protecting the intranet from the intrusion of illegal users. The so-called firewall is a barrier that separates the Internet from the intranet. Firewalls are available in two categories, standard firewalls, and two-home gateways. The standard firewall system includes a UNIX workstation that buffers each router at each end of the workstation. One of the routers interface is the external world, that is, the public network;

VPN English full name virtual private receptacle, Chinese translation as: Virtual personal network, also known as Virtual Private network. As the name suggests, virtual private network we can understand it as a virtual out of the enterprise internal line. It can establish a proprietary communication line between two or more corporate intranets that are connected to the Internet in different places via a special encrypted communication protocol, like a dedicated line, but it does not need to actually lay out physical wiring such as optical cables. This is like going to the Telecommunications Bureau to apply for a special line ...

Before the formal introduction, it is necessary to first understand the kubernetes of several core concepts and their assumed functions. The following is the kubernetes architectural design diagram: 1. Pods in the kubernetes system, the smallest particle of dispatch is not a simple container, but an abstraction into a pod,pod is a minimal deployment unit that can be created, destroyed, dispatched, and managed. 　　such as a container or a group of containers. 2. Replication controllers ...

This article shows how to setup an active-passive session-aware load balancing cluster (SLBC) consisting of two FortiGate-5000 chassis, four FortiController-5103Bs two in each chassis, and six FortiGate-5001Bs acting as workers, three in each chassis.

Redhatlinux provides firewall protection for increased system security. Firewalls exist between your computer and your network to determine which remote users on your network have access to the resources on your computer. 　　A properly configured firewall can greatly increase your system security. 　　Choose the appropriate level of security for your system. Advanced if you choose Advanced, your system will not accept connections that are not specifically specified by you (except for the default settings). Only the following connections are allowed by default: DNS response ...

This article shows some useful instructions for customers with multi-site architecture and redundant firewalls.

Introduction Cloud application developers and DevOps have successfully developed tens of thousands of applications for IaaS (Amazon AWS, Rackspace, etc.) and PAAs (Azure, Google App Engine, Cloud Foundry, etc.) platforms. These platforms provide basic security mechanisms such as authentication, Dos attack defense, firewall policy Management, logging, basic user and account management, but security concerns remain the primary obstacle to enterprise cloud implementations. Security concerns for the cloud, deploying from a secure configuration ...

The best security practice for developing Windows Azure applications describes what threats should be considered a major threat for applications running in Windows Azure. It also specifically describes the threats that Azure can mitigate and the content you need to invoke the API and what you need to handle yourself. (It does not address compliance issues.) What you should be dealing with I will select some threats and what you should do and provide some references so you can learn more about how to implement in code ...

The OpenLDAP software is designed to work in a variety of computing environments, ranging from controllable closed networks to global Internet.
