Many people complain that there are too many Windows vulnerabilities, and some even worry about one vulnerability after another. To this end, this article briefly introduces how to build a network security defense line.Disable useless servicesWindows provides many services. In fact, many of them cannot be used at all. You may not know that some services are opening backdoors for people who are eager to test.There are many services in windows, so I will not introduce them too much here. You can d
It's common knowledge that all the Cisco devices currently using the IPSec protocol to establish a VPN site is not the use of routing, or the use of GRE technology, GRE over IPSec can achieve routing, but that configuration complex does not say that, due to 2 of the package, the payload of each packet is much smaller, efficiency is not good. Also can only say at present, see the evolution direction of ASA, probably do not know when to import.
and currently using the strategy model is the majori

You can use zabbix to track network devices, services, servers, and applications for traditional Security Logging and analysis, as well as performance management and capacity planning.

This document describes the configuration of subnet overlapping IPSec VPN for all fortigate devices. When you configure VPN interconnection, you need to use NAT for address translation if the subnets on both ends overlap but cannot change any one end of the network to allow VPN connectivity. It is not recommended to use overlapping addresses at both ends of the VPN.

In this regard, Fortinet global chief market officer Richard Stiennon, in an exclusive interview with this newspaper, said that it is taking into account the needs of users, they launched to provide up to 26G firewall performance of UTM products-fortigate 3810A and 3016B. Of course, he admits that performance will fall below 50% when the full feature is turned on,
Description
This document for all FortiGate equipment block Thunderbolt, QQ configuration to explain. FortiOS4.0 uses control to identify more than 1000 applications, and can block them. Application control identifies applications through IPs eigenvalues. By applying control administrators, you can limit most of the illegal traffic and increase bandwidth utilization.

Section, from a fixed offset of the function code, and what we need to do is find it! On amd64, this is relatively easy. Check this Assembly:000000000000056c 56C: 55 push % RBP56d: 48 89 E5 mov % RSP, % RBP570: 8B 05 B2 02 20 00 mov 0x2002b2 (% rip), % eax #200828 576: 5D pop % RBPThis claims that "put the value at 0x2002b2 offset from the current Instruction Pointer (% rip) into % eax ". That is to say, we know that the data is at a fixed offset, so we have done it. On the other hand, i386 doe
% * [^ =] The variable is not saved with the * sign. Skips a qualified string.
char s[]="notepad=1.0.0.1001" ;
char szfilename [32] = "" ;
int i = sscanf( s, "%*[^=]", szfilename ) ;
// Szfilename = NULL because it is not saved
int i = sscanf( s, "%*[^=]=%s", szfilename ) ;
// szfilename=1.0.0.1001

% [^ =] Reads the string until '=' is reached. '^' can contain more characters, such:

buffer (buffer). SSCANF is similar to scanf and is used for input, except that the latter takes the screen (stdin) as the input source, the former with a fixed string as the input source usage: % [] means to read a character set, if [the latter first character is "^ ", it means" no ". The string within [] can be composed of 1 or more characters. The null character set (%[]) is a violation of the rules and can lead to unpredictable results. %[^] is also a violation of regulations. %[a-z] r
