Keep operating system patches up-to-date. Disable File and Printer sharing services. If these services are required, use strong passwords or Active Directory authentication. Restrict users' ability (permissions) to install and run unwanted software applications. Do not add users to the local administrators group unl Enforce a strong password policy and implement regular password changes. Exercise caution when opening e-mail attachments even if the attachment is expected and the sender appears to be known. Enable a personal firewall on agency workstations, configured to deny unsolicited connection requests. Disable unnecessary services on agency workstations and servers. Scan for and remove suspicious e-mail attachments; ensure the scanned attachment is its "true file type" (i.e., the extension matches the file Monitor users' web browsing habits; restrict access to sites with unfavorable content. Exercise caution when using removable media (e.g., USB thumb drives, external drives, CDs, etc.). Scan all software downloaded from the Internet prior to executing. Maintain situational awareness of the latest threats and implement appropriate Access Control Lists (ACLs).
