simple to review the Calico architecture and key components to facilitate understanding.
Calico Architecture
Calico is a three-tier data center network solution and facilitates integrated OpenStack, an IaaS cloud architecture that delivers highly efficient and controllable communication between VMS, containers, and bare-metal.
Combined with this picture above, we've been through Calico's core components: Felix,calico agent, running on each node that needs to run workload, is mainly responsible
supported.Figure 2. asp.net architecture on Windows Server 2003 with IIS 6The main difference in Windows Server 2003, compared to the ASP.net architecture under Windows 2000, is that you can host Web applications with different IIS worker process instances (W3wp.exe). By default, these applications are run using the NT authority\networkservice account, which is a least privileged local account that is used as a computer account across the network. Web applications running in the context of a ne
We know that there are four types of firewalls: integrated firewall capabilities of the router, integrated firewall capabilities of the proxy server, a dedicated software firewall and dedicated hardware and software combined with the firewall. Cisco's firewall solution includes the first and fourth of the four types: the integrated firewall feature router and the dedicated hardware and software combination firewall.

1. ACL technology in router
The CACLS command uses the following format:
CACLS filename [/T] [/e] [/C] [/g user:perm] [/R user [...]]][/P User:perm [...]] [/d User [...]]
filename--Displays the Access control list (ACL),/t--changes the acl;/e--edit ACL for the specified file in the current directory and all subdirectories,/c--continues when an Access denied error occurs, and/g gives the specified user access. Perm can be R (read), W (write), C (change, write), F (Full Control),/R user--revoke the access rights of the spe
1. How do I make ASP scripts run with system privileges?
Modify the virtual directory of your ASP script to change "Application protection" to "low" ....
2. How to prevent ASP Trojan?
ASP Trojan Horse based on FileSystemObject component
cacls%systemroot%\system32\scrrun.dll/e/D guests//prohibit guests use
regsvr32 scrrun.dll/u///delete
Note: So the FSO of the server can not be used;
Enter the following command on the cmd command line state:

Cisco 7200, 7600, or GSR, you're dead. How many M is the configuration of the move? It's scary. :)
2, about the extended access list.
First, there is a comparison with Ipv4.
IPv6 ACL is the same point as IPv4 ACL:
All two are made by IP five-tuple.
That is, 1 source IP address, 2 destination IP address, 3 Transport layer protocol, 4 source port number, 5 destination port number.
Differences between IPV6 and IPV4 ACLs:
In the ACL for IPV6, a ne
the public/private of course. Because SNMP is a fairly insecure protocol (especially a low version), you should also qualify a host that can access device SNMP through an access control list: After Snmp-server community xxxx RO/RW, you can add a standard or extended access control list. The console port can be equipped with a password, do not set no exec-timeout. The restriction of Telnet access is achieved by specifying Access-class in line vty; CatOS switches with IP permit-list; High-end dev
When a user modifies permissions on multiple files or folders, it is found that there is no Security tab in the property bar, which makes it impossible to modify them. How do we solve this problem? In fact, we can say to its bulk operation, can save a lot of time.
Method One:
1, through the way of command, first use the Administrator user Login system, and then open a command Prompt window, in the command-line program to enter the ICACLS command of the folder or file permissions to make change

name. It's just that they are safely certified and not duplicated, which is safe and reliable. If we mention Zhang San this user's SID, then we can be understood as "Zhang San (true)".
Security descriptors (Safety descriptor)
MSDN says the security descriptor contains security information that describes a securable object. In fact, this sentence is very right, but it is probably on the. Let's look at exactly what the security descriptor describes? Security descriptors include: 1
Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple network application protocol TCP/UDP port numbers in general ACLs. For example, the TCP 80 used by well-known WEB applications can also control the protocols that generally cannot achieve dynamic ports in

Both Windows 2000 and Windows XP provide you with the option to enable the operating system to log on automatically with the specified user creden。 at startup. Although this provides great convenience, it makes it easy for unauthorized users to access your data. At home, automatic login is not always a bad choice, but if you travel with the company's important information, it is an unwise choice.To disable

When using the named Access Control List, the vroios IOS 11.2 or later versions are required, and multiple ACLs cannot be named with the same name. Different types of ACLs cannot use the same name.
