Despite the abundance of tools that test code and help improve the effectiveness of a continuous integration pipeline, automated security testing is much more difficult to get right than it might appear.
Add extra security to your SSH service, securely copy files to and from remote computers, and configure passwordless SSH for automation scripting.
Use Microsoft SQL Server diagnostic tools to troubleshoot bottlenecks and other performance problems.
A natural consequence of software-defined storage and software-defined data centers is the software-defined wide area network, or the Internet connections between locations and cloud services.
Even in the best environments, a little housekeeping is necessary.
VMware's NSX for vSphere platform adds security to microsegmentation, allowing security components to analyze traffic within the hypervisor.
Virtualization solutions isolate their VM systems far more effectively than a container host isolates its guests. However, implementation weaknesses in the hypervisor and configuration errors can lead to residual risk, as we show, using KVM as an example.
Although developers appreciate Docker's ease of use and flexibility, many admins are worried about vulnerabilities. We look at various approaches to securing container images and the price to be paid.
Any OpenStack installation that hosts services and VMs for several customers poses a challenge for the security-conscious admin. Hardening the overall system can turn the porous walls into a fortress – but you'll need more than a little mortar.
Microsegmentation promises substantial improvements over classic architectures for the protection of applications and increased security when building out the efficiency of a data center.
