deploy the firewall in the network. However, in the networks of large enterprises, firewalls and Security routers play a different role in routing and security functions. What should they do if they correspond to professional firewalls in addition to secure routing, as well as software firewalls, UTM, and other products?
The Software Firewall runs on a specific computer and needs the support of the computer operating system pre-installed by the custo
point. Therefore, before the Y-value, it needs to be labeled with a band number, and such coordinates are called universal coordinates.Comparison of 3.2 Gauss G Gauss–krüger projection with UTM projectionThe UTM projection, called Universal Transverse mercatol PROJECTION (Universal Transverse Mercator), is a "conformal transverse cylindrical projection", which cuts the Earth at 80 degrees south latitude, 8

The security router is mainly used in the network center of small and medium-sized enterprises. It undertakes the main routing functions while taking into account network security. However, the overall network performance of the entire device cannot be degraded due to security functions. That is to say, security is an auxiliary function of the security router. In small and
) Gaussian-gram projection and UTM projection
Some foreign software, such as ARC/INFO or supporting software of foreign instruments, such as multi-beam data processing software, often does not support Gaussian-gram projection, but supports UTM projection, therefore, the UTM projection coordinates are often submitted as Gaussian-gram projection coordinates.
axes is the coordinate origin of each belt. The ordinate coordinates start from zero in the equator. The north of the equator is positive, and the south is negative. China is located in the northern hemisphere, and the ordinate values are positive. If the x-axis starts from zero in the central longitude line, the East of the central longitude line is positive, the West is negative, and the X-axis has a negative value. Therefore, it is inconvenient to use the x-axis to move 500 kilometers west a
Use Zabbix to monitor corporate firewalls through SNMP
The company uses the FortiGate 80C firewall, and now uses Zabbix to monitor its status through SNMP.
Add the -- with-net-snmp parameter to compile and install zabbix.
First, Enable SNMP on the firewall, and then add a host in Zabbix

How enterprises consider their network protection devices
In addition to powerful routers (such as Cisco, Huawei, and 3Com), most of the companies that are willing to invest in it have security devices such as UTM, IPS, and Web security gateway. Of course, we must not forget the common firewall that has been working hard for a long time (non-integrated security gateway ). Today, we will talk about the considerations of network protection solutions

Recall that the professional contact with remote sensing for several years, and now more and more deviated from remote sensing, suddenly thinking of their own brain in the remote sensing knowledge to sort out. The first thought is the coordinate system and projection, I think this thing bothers more than 80% of surveying, remote sensing and GIS practitioners in the field, the group often asked, I was also very confused, what Earth coordinate system
Looking back, I have been in touch with remote sensing for several years, and now I am moving away from remote sensing. I suddenly want to sort out the remote sensing knowledge in my mind. The first thing that comes to mind is the coordinate system and projection. I think this is bothering more than 80% of practitioners in the field of surveying, remote sensing, and GIS. People in this group often ask me that I was also confused, what earth coordinate system, Earth coordinate system, Gaussian pr
I have got Ed a lot of questions on how to transform data from one coordinatesystem to another on the fly in sharpmap. usually the problem is that they have data in different coordinatesystems and want to match them. although I wowould recommend applying transformations once-and-for-all to increase performance (you cocould use OGR for this), it is easy to setup in sharpmap. below are some examples on how to accomplish this.
Sharpmap gives you the full power to specify all the parameters in a pro
coordinate system (such as UTM-universal horizontal axis mocato projection, location Information is expressed in meters or feet ).
The information contained in a geographic coordinate system has a (which contains a torball body represented by the reciprocal of the long half axis and flat rate), a central Meridian (usually the primary meridian, that is, 0-degree longitude line Greenwich), there is also an angle measurement unit, using degrees rather t
If divide and conquer is a successful strategy to solve the problem, then the invasion defense is still in the stage of differentiation. Most networks use firewalls, and many use IDs, which have anti-virus and anti-spam software, and some use IPs on some networks. But none of the distributors combine these technologies into one whole and manage them, making it easier to use.
In terms of the whole process, most network managers have a large number of efficient control ports on their networks, bo

These tools allow defining coordinate systems in a series of formats (SRS is the space Reference System spatialreference system ). SRS can be specified in the following ways:

The FortiGate SSL VPN feature uses SSL and proxy technology to enable authorized users to secure reliable Web clients, server-side applications, or other file resource sharing services. FortiGate SSL VPN works only under NAT mode, and transparent mode does not support SSL VPN functionality. FortiGat

This document describes the Web content filtering configuration for all fortigate devices. FortiGate can identify and filter Web pages that contain certain words. Web content filtering is one of the most effective ways to restrict a user's access to a particular type of Web site. This document illustrates the specific use of this feature by blocking the stock page. Web pages that block other co
