Question:Most firewalls or UTM deployment modes include the routing mode, the bridge mode, and the hybrid mode. The core configuration is the write rule, A good rule will greatly improve the security of the internal network. Of course, if UTM is used, other security components may be attached. For example, the most common rule is the AV anti-virus component, IPS components, anti-spam components, and some ot
solutions to prevent network viruses, Web Application Security authentication, and other issues. However, IDS/IPS technology lays a good technical foundation for future network security, many of the new Web application firewalls and next-generation firewalls are derived from IDS/IPS. In addition, IDS/IPS still have broad technological development prospects.
Unified Threat Management for network security products (UTM)
To address the challenges of net
Traditional firewalls, next-generation firewalls, Web application firewalls, UTM, cloud firewalls, etc., are you being selves here by these nouns, are they the concept of a manufacturer or are they really used? In the complex firewall market, who will stand out and lead the enterprise to the future safety road? Today, we will discuss the development of firewalls and trends.

Firewall is a combination of software and hardware d
Best 10 methods for implementing URL filtering
URL filtering is a filter that allows or prevents users from accessing a specific website. This method has become a basic method on the enterprise network. Its goal is to prevent employees from accessing content that may impair efficiency or the company's interests. Blocked websites may be websites that threaten Enterprise Security, contain malicious content, or consume a large amount of bandwidth.
URL filtering can enhance network security and en
) 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

filter has the advantages that are unmatched by vendors that only provide simple URL filtering.
Programmers are constantly looking for new ways to improve the success rate, and spreading malware through legitimate websites is undoubtedly a very effective method. IronPort's Web reputation filter identifies where the redirection is to be sent so that requests can be blocked before any malware enters the network. Simple URL filtering cannot separately d
the pro version, almost twice that of the pro version. In addition, enterprises that require Windows business performance need to apply for Software Assurance licenses for those computers. Microsoft's software maintenance projects), this License costs 30 to 50 dollars a year. In this case, compared with the security performance of products provided by third-party vendors, is Windows 7 worth the additional cost?

BitLocker to Go require more expensive systems to run, such as Windows 7 Enterprise Edition and Windows 7 flagship edition. The cost of upgrading to these versions is about 10% higher than that of the pro version, almost twice that of the pro version. In addition, enterprises that require Windows business performance need to apply for Software Assurance licenses for those computers. Microsoft's software maintenance projects), this License costs 30 to 50 dollars a year. In this case, compared wi

cannot fully reflect the performance of network products.
I personally think. Measure the performance of a network product. It should be comprehensive. In addition to the most basic performance indicators, the functional performance of the product should also be tested.
For example. If a product has a VPN function. In addition to the above indicators, we should also test the performance of VPN.Including the VPN throughput, the number of new tunnels per second and the maximum number of VPN tunne

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
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
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
