EventTracker: Removable Media Device Monitoring Version 7.x EventTracker 8815 Centre Park Drive Columbia MD 21045 Publication Date: Dec 21, 2011 www.eventtracker.com EventTracker: Removable Media Device Monitoring Abstract With the introduction of newer portable devices, the security needs of protecting integrity and confidential data has been changed. An increasing need of portable access to the data has also increased the risk of sensitive or confidential data exposure. Therefore, to keep a record of removable media device activities has become one of the most important compliance factor for the enterprise. EventTracker’s advanced removable media monitoring capacity protects and monitors system(s) from illegal access or data theft. EventTracker helps user(s) to disable the unauthorized access to the machine and allow the trusted devices connection. Purpose This document will help you to enable the removable device monitoring and explains the procedure to find the Device ID and USB serial number. It also monitors insertion/removal and files written to and read from removable media such as CD/DVD and USB. Intended Audience Administrators who are assigned the task to monitor and manage events using EventTracker. Scope The configurations detailed in this guide are consistent with EventTracker Enterprise version 7.x. The instructions can be used while working with later releases of EventTracker Enterprise.

They have many shapes as flash memory drives, cell phones, cameras, and PDAs that can serve as storage devices. These portable devices are convenient for transfer and storage of large data with or without network access and that too in short time. However, with all these advantages, it has some security vulnerabilities. In modern day enterprise, USB data transfer is the simplest way of Data theft. The chances of data leakage, creation of duplicate documents and illegal data transfer etc has also increased. As a SIEM solution, EventTracker not only has the ability to monitor the USB or removable media device communications, but it also can identify the trusted USB and other devices. You can define the unique identifier number of the USB so that the device will not be disabled upon insertion, and can access the information from system. EventTracker Monitoring Features Reports insertion / removal of the removable device EventTracker will log every activity of the USB or other removable media device like plug-in, plug-out, or data transfer etc. A complete audit trail that consists of the user, device type, serial number, time and all the file activities are captured, and sent as an event to the EventTracker Console for processing. Prevents unauthorized access and reports the intrusion in real time Every time an USB is inserted, the EventTracker agent looks at USB exception list, and if there is no violation of policy, permits access to the device, while logging the insert activity. If a violation of policy is detected, access is prevented and the violation is immediately sent to the EventTracker Console. At this point if access is permitted, EventTracker also begins to monitor all the activities on the device, and every file that is written to or deleted from the device is recorded. Restricts Access EventTracker can restrict access to all the USB Devices on a particular system, and also can exempt the specified USB devices from monitoring which are added in the USB Exception list. 3 EventTracker: Removable Media Device Monitoring Protects the system from malware EventTracker can disable the USB or other removable media device upon insertion, and thus safeguards the network from viruses and Trojans. Logging USB device communication For the security and compliance purpose, EventTracker logs the USB communication in detail as incidents. Figure 1: Event Properties Get Alert notification In EventTracker, user can configure alerts to receive the notification upon removable media activities.

    Use External Storage Devices Like Pen Drives, Cds, and Dvds

    External Intel® Learn Easy Steps Activity Card Storage Devices Using external storage devices like Pen Drives, CDs, and DVDs loading Videos Since the advent of computers, there has been a need to transfer data between devices and/or store them permanently. You may want to look at a file that you have created or an image that you have taken today one year later. For this it has to be stored somewhere securely. Similarly, you may want to give a document you have created or a digital picture you have taken to someone you know. There are many ways of doing this – online and offline. While online data transfer or storage requires the use of Internet, offline storage can be managed with minimum resources. The only requirement in this case would be a storage device. Earlier data storage devices used to mainly be Floppy drives which had a small storage space. However, with the development of computer technology, we today have pen drives, CD/DVD devices and other removable media to store and transfer data. With these, you store/save/copy files and folders containing data, pictures, videos, audio, etc. from your computer and even transfer them to another computer. They are called secondary storage devices. To access the data stored in these devices, you have to attach them to a computer and access the stored data. Some of the examples of external storage devices are- Pen drives, CDs, and DVDs. Introduction to Pen Drive/CD/DVD A pen drive is a small self-powered drive that connects to a computer directly through a USB port.

  • USB Flash Drive Security Recommendations and Best Practices

    USB Flash Drive Security Recommendations and Best Practices

    USB Flash Drive Security Recommendations and Best Practices Risks USB flash drives or thumb drives pose a severe security risk to networks and data. Hackers can use them to transmit viruses and other malware every time they are plugged into another computer. Attackers may also use USB drives to steal sensitive information. USB drives are also easily lost or stolen. If the data was not backed up, the loss of a USB drive can mean hours of lost work. If the information on the drive is not encrypted, anyone who has the USB drive can access all of the data on it, potentially causing a data breach or leak Personally Identifiable Information (PII). Recommendations Staff are encouraged, and possibly required, to use authorized removable media with their devices for work-related functions. Sensitive information generally should not be stored on removable media in order to mitigate the risks mentioned above. If use of removable media is required for their work, it should be encrypted and placed only on officially registered removable media devices. Best Practices Use Office365 OneDrive or another cloud backup service to securely store and access data. This also protects against potential data loss when the loss of a removable device. If you must use a USB drive, use passwords and encryption to protect the data. Keep personal and business USB drives separate - Do not use personal USB drives on computers owned by the organization, and do not plug USB drives containing work information into a personal computer. Use and maintain security software, and keep all software up to date - Use anti-virus software, and anti-spyware software to make your computer less vulnerable to attacks, and make sure to keep the virus definitions current.
