  • IBM Tivoli Endpoint Manager for Patch Management Continuous Patch Compliance Visibility and Enforcement
    IBM Software Data Sheet Tivoli IBM Tivoli Endpoint Manager for Patch Management Continuous patch compliance visibility and enforcement With software and the threats against that software constantly evolving, Highlights organizations need an effective way to assess, deploy and manage a con- stant flow of patches for the myriad operating systems and applications in ● Automatically manage patches for multi- their heterogeneous environments. For system administrators responsible ple operating systems and applications across hundreds of thousands of end- for potentially tens or hundreds of thousands of endpoints running vari- points regardless of location, connection ous operating systems and software applications, patch management type or status can easily overwhelm already strained budgets and staff. IBM Tivoli® ● Reduce security and compliance risk by Endpoint Manager for Patch Management balances the need for fast slashing remediation cycles from weeks deployment and high availability with an automated, simplified patching to days or hours process that is administered from a single console. ● Gain greater visibility into patch compli- ance with flexible, real-time monitoring Tivoli Endpoint Manager for Patch Management, built on BigFix® and reporting technology, gives organizations access to comprehensive capabilities ● Provide up-to-date visibility and control for delivering patches for Microsoft® Windows®, UNIX®, Linux® and from a single management console Mac operating systems, third-party applications from vendors including Adobe®, Mozilla, Apple and Java™, and customer-supplied patches to endpoints—regardless of their location, connection type or status. Endpoints can include servers, laptops, desktops, and specialized equip- ment such as point-of-sale (POS) devices, ATMs, and self-service kiosks. Apply only the correct patches to the correct endpoint One approach to patch management is to create large patch files with a large update “payload” and distribute them to all of the endpoints, regardless of whether they already have all of the patches or not.

  • Carlos Guardia Rivas Ibm Spain
    CARLOS GUARDIA RIVAS IBM SPAIN EXECUTIVE IT SPECIALIST - IBM SOFTWARE GROUP WHAT IS THE ROLE OF DATA WITHIN YOUR ACTIVITY AT IBM? IBM is closely related to data and is a big data producer. For example, a few years ago IBM bought The Weather Company. This company generates climate data, compiles it and sells it to, especially, insurance companies and also to other private companies that make use of this kind of data. Even if IBM uses external data repositories, it is mainly a data producer. As for the tools, at IBM we have a very complete portfolio of analytics tools, ranging from importing data from diverse sources, data integration in diverse formats, data cleaning, replication to other systems if needed… Our most famous analytics tool is Watson, which is basically a set of tools that allows you to do any kind of projection on the data: from visualization to prediction. In conclusion, we are a company that offers solutions in the main data-related areas. This is the field in which IBM is heavily investing. DOES IBM USE OPEN DATA FROM PUBLIC SOURCES? We mainly use our own IBM-produced data and tools. We have a big variety of databases: structured, non-structured, analysis-oriented… CONSIDERING THAT MOST OF THE DATA IS GENERATED BY IBM, WHAT KIND OF STANDARDS DO YOU APPLY? Our own customers demand us to adjust to specific standards when they use our tools. Therefore, we comply with all the typical standards in data management. If we didn’t do so, we wouldn’t sell anything! We are always keeping an eye on the market’s demand for specific standards.
