. Because generally speaking, the smaller the office size, the fewer users, the lower the risk faced. As a result, simple packet-filtering firewalls are sufficient for small offices, such as those that are randomly brought by many DSL or cable routers. These include broadband routers from companies such as D-link, 3Com, Netgear and Linksys. In addition, WatchGuard Firebox Soho, Symantec Firewall 100, global technology company Gnat, NetScreen and Sonic

of ISS is a class of software IPs. RealSecure Guard detects attacks through an anomaly protocol and can intercept them in real time before they reach the target host. NetScreen, which focuses on firewall development, is also developing in this field. IPs developed by NetScreen's Onesecure company is based on a dedicated ASIC implementation. NETSCREEN-IPD 100 has a Fast Ethernet interface with a maximum th

implemented on juniper's firewall for a long time. The current asa is much worse than the early netscreen, and the gap will be said later. The following describes the configuration. Instead of using the original direct address, the IP address range defined by netscreen is long ago ). Description structure: the address of the local VPN site is 172.26.7.0/24, and the address of the Peer abc Company is 10.24.

high-end gigabit firewall popular choice. The second option is to use the architecture based on ASIC technology. NetScreen is the representative manufacturer of the technology. ASIC technology can be designed for the application of the firewall specialized data packet processing pipeline, optimize the use of storage resources, is recognized as a firewall to achieve line-speed gigabit, to meet the gigabit environmental backbone of the application of t

Method 1: People who have used juniper products should know a little, juniper product password Forget the words is a very painful thing, why say so? Come down and listen to what I have to tell you! The loss of the password is unrecoverable, so we have to regain administrative privileges by restoring the factory default settings (the original configured parameters, certificates, etc. will be deleted). There are two ways to restore the factory default configuration: 1. In console mode, use the

enterprises can even compress multiple firewalls into one firewall, thereby further simplifying and enhancing network security. As an essential network component, the Juniper Network corporate firewall provides an extremely high availability for the enterprise and can interoperate with existing network infrastructures. Juniper Network Company's firewall/VPN solution can be deployed with the NETSCREEN-IDP of Juniper Network company.

. If you do not want to use the system's built-in IPSec software, even if it is based on Microsoft's Point-to-Point communication Protocol PPTPPoint-to-Point Tunneling) or L2 Channel Protocol L2TPLayer Two Tunneling Protocol ), it can also perform 2000 session communications at the same time. In combination with VPN networks, Cisco's PIX firewall software can also be used to configure 7140 as a firewall ), this means that Cisco 7140 provides dual-insurance-encryption and firewall for your LAN to

Cisco is better than iptables after all... I made a DNAT for the subsidiary... opened the two ports on the firewall... It's quite simple to do DNAT, but I'm not familiar with it. I turned netscreen to the next day yesterday, and I didn't find anything about it... it seems that Nat is still done on the vro. Find an IP address and search for it. I rely on it. It's actually the IP address of the vro, it seems that this SNAT was made on the company's

MiB is a collection of managed objects. It defines a series of attributes of the managed object: Object Name, object access permission, and object data type. 4) oId (objectidentifier): object identifier. The managed object is represented by OID. The monitoring of network devices mainly involves two aspects: 1) port traffic of netw

the hardware architecture is designed with high-speed interface technology and Bus Specifications, with high I/O capability. In this way, the packet processing capability of network devices based on network processors has been greatly improved. It has the following features: completely programmable, simple programming mode, maximum system flexibility, high processing capability, high function integration, open programming interfaces, and third-party support capabilities. Compared with the gener

What kind of software is Nipper? In fact, Nipper is short for Network Infrastructure Parser. It should be said that it is a Network architecture Parser. Nipper is an open-source network device security audit tool. The advantage of open source is of course its free nature. Previously called CiscoPars, Nipper has a simple interface, but is powerful and easy to install and use. It can accurately complete the promised tasks. Nipper can process network device configuration files, perform security aud

Suddenly one day, found that this computer browsing the internet at times when the break, ping the address on the Internet, but also pass, break, but ping intranet when there is no problem, and intranet communication is also very normal, that is, and the Internet communication has this phenomenon, very confusi

Cisco announced it would check whether the software contains backdoor code After Juniper's firewall product NetScreen finds two backdoors, Cisco announced that it would re-examine its software in case it contains backdoor code. The backdoors of Juniper are considered to be hidden in the elliptic curve encryption algorithm, and the backdoors of Juniper are a secret password for managing access permissions. Cisco said they should be able to discover un

ByYunshu The previous blogs have been written too long. Today, I want to talk about the problem of permission expansion. This problem also exists in the WEB system, but I only pay attention to network issues here.Most companies use Active Directory to manage the company's PC and employee information. network devices use the user name and group information in the DC for authentication and authorization. For example, NetScreen UAC, Array VPN, Cisco VPN,
