Telework Best Practices

This joint NSA/DHS CISA slicksheet was designed during the era of COVID-19 to provide a list of “dos and don’ts” as they relate to telework. Helpful for end users using government-owned or personal devices.

Mobile Device Best Practices

This succinct guidance details steps end users may take to better protect their mobile devices and data.

Selecting and Safely Using Collaboration Services

This document provides security assessment guidance about commercially available collaboration services to enable the Department of Defense and other U.S. Government customers to most securely use collaboration platforms who do not have access to a government provided tools, accounts, or equipment.

Best Practices for Securing Your Home Network

Don’t be a victim; cyber criminals may leverage your home network to gain access to personal, private, and confidential information. Help protect yourself and your family by observing some basic guidelines and implementing the following mitigations on your home network.

Keeping Safe on Social Media

This brief guide highlights critical information and countermeasures users may take to help keep themselves and their sensitive data safe while connecting with others on social media.

Limiting Location Data Exposure

Mobile devices expose location data, and there is an associated risk that comes with using them. This report summarizes how and why location data might be shared and provides mitigations to limit this sharing, but warns there is no solution to fully protect a mobile device from being located.

Identity Theft Threat and Mitigations

Criminals can use a multitude of methods to obtain personally identifiable information, which can be used to carry out malicious actions. Personal protection from these actors must be dealt with on all fronts, as a layered approach. The information provided in this document is designed to help individuals protect themselves against identity theft and mitigate the risk.

Steps to Securing Web Browsing

Web browsers pose a unique risk to enterprise infrastructure because of their frequent exposure to untrusted dynamic content. Configuring browser security settings is challenging due to uncertainty of both attack mitigation effectiveness and impact on end users. A key goal of this paper is to avoid impact to users while also mitigating as many attacks as possible.

Mitigating Recent VPN Vulnerabilities

Multiple Nation State Advanced Persistent Threat actors are weaponizing known vulnerabilities to gain access to VPN devices. This document shares actions for compromise recovery and long-term hardening. Helpful for any net defenders or end users responsible for maintaining VPNs.

Securing IPSec Virtual Private Networks (VPNs)

This identifies common VPN misconfigurations and vulnerabilities and an overview of the ways to secure your VPN.

Configuring IPSec Virtual Private Networks (VPNs)

This guidance provides a more in-depth look at how to implement specific configurations for securing and maintaining secure VPN connections.

TENS Virtual Machine Guide

The United States Air Force Trusted End Node Security (TENS) solution allows authorized DoD teleworkers to connect to DoD sites and services from untrusted devices, such as personal computers. This guide provides detailed instructions for configuring a virtual machine to boot TENS until TENS is able to load when a computer uses UEF Secure Boot.
