  • AWS instance types come in many shapes and sizes

    AWS instance types come in a wide range of options, each geared to specific purposes and workloads. This three-part guide looks at the different kinds of AWS instance types and common uses for each. It also explains how to best choose instance types, how to move from one instance type to another and takes a look at AWS hosting costs.

    You need to choose the correct AWS instance type for your workload or you'll end up paying too much and likely underutilizing that instance type -- with Amazon cloud pricing models, you're paying for spinning resources that you're not using. Some companies use Reserved Instances for workloads they know will be running for one to three years. Others choose (and bid on) spot instances, for one-off projects. On-demand instances are charged at a fixed rate per hour, often for test and dev projects, so an AWS cost calculator helps provide cost certainty.

    In 2016, Amazon introduced a new pricing model for AWS Reserved Instances. While this model may result in savings, there's question of whether it will be worth it when the additional management overhead is factored into the equation.

  • slack space (file slack space)

    Slack space is the difference between its logical and physical size. The logical size of a file is determined by the file’s actual size and is measured in bytes.

  • Fighting crimeware, RAM scraping and other modern mischief

    There's a good possibility that the attacks you see this year will be harder to detect than in years past, particularly as malware generation toolkits make these more advanced techniques easy to incorporate with existing systems.

    In this three-part guide, SearchSecurity contributors examine the latest iterations of malware. First, however, is a chapter on crimeware in general -- that is, malware used to conduct crime. Not surprisingly, that means grabbing sensitive personal information from either point-of-sale terminals or individual end users. The ultimate goal is the same either way: To get at the money. Investigation is essential to understanding and preventing attacks, so we've included some guidance on how a formal investigation should proceed. Later, particular methods of malware users are explored in depth -- RAM scraping and advanced evasion techniques.

    This guide provides a valuable rundown of what's coming at you in the months ahead from the world of malware, and helps determine what you must do to keep your enterprise systems and finances secure.
