IronPort is a widely used email encryption gateway that can seamlessly encrypt, decrypt, and
grandfather class has a virtual table pointer. Therefore, after obtaining the starting address of the object, the compiler adds a 4-byte offset to skip the virtual pointer. The actual calculation of the obtained address is: [EBP + ECx + fffff7f0h + 4 H]. The compiler will directly perform the last operation when generating the code.
Virtual inheritance of diamond structure (2)
Let's look at another example. The Inheritance structure of this example is the same as that in the previous article. I
, after obtaining the starting address of the object, the compiler adds a 4-byte offset to skip the virtual pointer. The actual calculation of the obtained address is: [ebp + ecx + FFFFF7F0h + 4 h]. The compiler will directly perform the last operation when generating the code.Let's look at another example. The Inheritance structure of this example is the same as that in the previous article. It is also a diamond structure. The difference is that each class overwrites the top-level class declara
Postscript
Based on the previous discussion, we can see that as long as virtual inheritance is involved, the code generated when accessing the member variables of the parent class is quite inefficient, the address of the member variable needs to be located through many indirect calculations. During pointer type conversion, dynamic transformation, and virtual function calling, you also need to generate a lot of additional code to adjust this pointer. Like the obj. Foo () and obj. f170 () of the c
This is no longer a secret-network threats have become more common and complex than ever before-it is difficult to rely solely on a single anti-virus solution.
Many malicious Trojans and worms, such as Koobface and Conficker, are used to snoop key records and plagiarize sensitive information, causing serious damage to the enterprise network. At the same time, many network security solutions are also widely used in small and medium-sized enterprise organizations, because more and more enterprises

"The OpenSUSE community received a report about the bug that the IronPort SMTP server encountered an exception block due to the recent modification to the padding extension code due to the OpenSSL heartbleed vulnerability. OpenSSL 1.0.1g not only fixes the heartbleed vulnerability, but also adds some modifications to the padding extension:
# Define TLSEXT_TYPE_padding 21
This directly causes an SSL Link error (at least on the Ironports device ):

Cloud Firewall is a new concept, the first by the IT giant Cisco proposed, their approach is: upgrade their firewalls to the "cloud" firewall, to achieve dynamic prevention, active security.
Cisco believes that the emergence of the cloud firewall means the emergence of the fifth generation of firewalls (the first four generations are: software firewalls, hardware firewalls, ASIC firewalls, UTM). The 4 characteristics of cloud Firewall include: Anti-Zombie network/trojan, prevent network interna
