Event management, although theoretically different, is fundamentally what most IT organizations refer to as “monitoring.” Monitoring an organization’s environment to determine whether important assets are in the state they should be, and knowing when that state changes, is a very important activity that many organizations spend significant portions of their budget doing.
A strong event management process that is able to detect changes of state throughout an organization’s IT environment is a key aspect of a complete suite of service management processes. Event management ultimately helps an organization maintain control through an understanding of the state of things, and how the state of those things changes in an IT environment.
Cisco Internetwork Operating System (IOS) has been around since a little after the inception of Cisco Systems as a company. In 1984, Len and Sandy Bosack from Stanford University founded Cisco Systems with a small commercial gateway server. The first Cisco router that I touched was an Advanced Gateway Server (AGS), which was the first marketed product of the company. After this came the Mid-Range Gateway Server (MGS), the Compact Gateway Server (CGS) and later the Integrated Gateway Server (IGS) and AGS+. The first version of IOS that I touched was 8.2(7). The operating system was based on a Unix-based system and was designed as a monolithic operating system, meaning that processes are stacked and interrelated.
The VMware NSX platform combines networking and security functionality directly in the hypervisor and it interoperable with a vast majority of VMware’s products. The platform provides a set of logical networking elements and services, using logical switching, routing, load balancing, VPN, firewall, etc. This product decouples network functionality from the physical devices.
In 2013, Cisco released their Software Defined Networking (SDN) solution for the data center known as Cisco Application Centric Infrastructure (ACI). For many years, the networking industry has been asking for an approach to configuring networking devices more efficiently than having to individually configure each and every router and switch.
Data center return on investment – which is measured by time to cost savings, time to revenue, time to break even, etc. – has proven more elusive than expected. But that doesn’t mean it isn’t attainable. To understand the genesis of the bad and ugly parts of data center ROI, we need to recognize the good parts and appreciate why so many companies are putting their faith in new and unfamiliar technologies.
Consider how many financial transactions are performed on the Internet everyday. Protecting all this data is of upmost importance. Cryptography can be defined as the process of concealing the contents of a message from all except those who know the key. Cryptography can be used for many purposes, but there are two types of cryptographic algorithms you need to understand, symmetric and asymmetric. Symmetric uses a single key, whereas asymmetric uses two keys. What else is required to have a good understanding of cryptography? It’s important to start with an understanding of how cryptography relates to the basic foundations of security: authentication, integrity, confidentiality, and non-repudiation.
Google takes security to a whole new level thanks to their years of experience as one of the most popular targets on the internet for would-be hackers and denial of service bots. This led Google to build a sophisticated security infrastructure the likes of which few companies or organizations can claim. Google approaches security holistically and involves everything from the physical data centers, to the data pipelines between them, down to the training of each employee that is responsible for managing the infrastructure.
Despite a growing awareness and preparation for distributed denial-of-service (DDoS) attacks, the overall arc of DDoS attacks is not weakening, but actually gaining more attention from the companies and personnel who have experienced these threats first-hand.
Have you been afraid to implement PowerShell in your environment because of security fears? The reality of PowerShell security doesn’t always match the perception. When compared to other scripting languages, PowerShell is actually more secure by default.
