Xen Hypervisor Security

When you joined the Xen Summit last week, you heard the XCI (Xen Client Initiative) project (see Xen Cloud Platform (XCP)), Xen clients hypervisor:the Ultimate The "project is" to Define a standard framework for supporting service domain virtual Applian ...

Cloud computing is able to provide a virtualized pool of resources, flexible service capabilities, self-service, etc., won the CIO's favor, in order to improve the utilization of IT equipment, improve the capacity of service disaster, improve the rapid response to business support, the majority of enterprises are beginning to try the private cloud construction. The embarrassing situation of private cloud security in general, the transition from the existing IT management system to the private cloud platform requires several steps: Large data centralization, business system integration, virtualization of IT resources, management platform cloud, and cloud service delivery. (many people think that private clouds ...

September 23, virtualization technology for the Linux kernel Xen was given a hat-trick with 3 security vulnerabilities. Xen vulnerabilities can be jumped out of the virtual host environment (ultra vires), or read other user data, control the hypervisor itself (host). A remote attacker could exploit a vulnerability that could cause the host system to crash and deny service to legitimate users. Xen Vulnerabilities and impact range is not small, such as Amazon AWS Large-scale restart server-the entire repair cycle lasted 5 days (from September 25 7 o'clock in the afternoon to September 30 5 o'clock in the afternoon), impact ...

Over the past few decades, firewalls have been a port-based guardian of the Internet. 　　Now vendors are scrambling to roll out so-called "next-generation firewalls" because these "application-aware" firewalls can monitor and control access based on application usage. In addition, many firewalls have added more and more features to try to discover the 0 attacks, including intrusion prevention systems (IPS), web filtering, VPN, data loss protection, malware filtering, and even threat detection sandbox. For a separate IPs, because of its application control, it may be called "Next Generation IPs" ...

In recent years, cloud computing is a very popular research field, in fact, it is not a new technology, but a lot of technology integration, including distributed computing, dynamic and expansion of a variety of technology algorithms, and virtualization is the most important technology in cloud computing. Cloud security is a key and challenging issue in the development and application of cloud computing technology. Through the network of a large number of clients to Internet software behavior anomaly monitoring to obtain the Internet Trojan, malicious program of the latest information, pushed to the cloud server to automate the analysis and processing, and then the disease ...

Recently, think of a High-profile release server virtualization New XenServer6.1, and in the Beijing office of Si Jie Media communication will be held. Cloud computing era, do front-end virtualization Jie in the mobile office, BYOD and other areas of development, however, this too dazzling light seems to play down the role of XenServer in the back-end market, coupled with Microsoft in the field of server virtualization increasingly close cooperation, 　　Let many observers begin to jie the strategic imagination of the server virtualization market. Recently, Si Jie high profile publishing Server virtualization ...

Virtual Machine Management program is a commodity, then where do we go? 　　Virtualized physical computers are the backbone of the public cloud [note] and private cloud [note], enabling enterprises to optimize hardware utilization, enhance security, support multi-tenant, and so on. Early virtualization approaches were based primarily on analog CPUs, such as x86 on PowerPC Macs, enabling users to run DOS and Windows. 　　Not only do you need to simulate CPUs, but you also simulate other components in your hardware environment, including graphics adapters, hard disks, network adapters, memory, and interfaces. ...

While it is difficult to change the business process, it is only a broader obstacle to the adoption of cloud technology.　　For many businesses, regulatory and security issues are another important barrier to preventing them from moving to the cloud. 　　San Francisco: Amazon Web Services (AWS) has intensified its collaboration with Oracle, specifying a separate part of its cloud infrastructure for running Oracle virtualization technologies and applications on preconfigured Amazon Machine Images (AMIs). For Oracle users, this collaboration means that ...

Last month, SuSE released version 2.0 of the OpenStack-based enterprise-class private cloud SuSE Cloud, a new feature of concern, including support for OpenStack block Storage, OpenStack Networking, More robust installation processes, as well as increased support for Microsoft Hyper-V, and more. "A cloud environment that supports mixed hypervisor can help companies better plan for the future, while ensuring that previous investments are not wasted," he said. "SuSE Cloud solves ...
