Military and intelligence agencies manage extremely sensitive information, and their missions often require them to operate in high-risk environments where even the slightest breach of security or sensitive data exposure means disastrous results to the mission and to national security. Their most vital networks are air-gapped\u2014disconnected from the internet\u2014so cloud-native security tools cannot secure these sensitive assets.<\/p>\n\n\n\n

There is a myriad of reasons organizations choose to air-gap their systems. To effectively secure classified networks, weapons systems, tactical field systems and critical infrastructure, agencies are faced with the challenge of building and maintaining a security strategy involving endpoint, network and data security defenses that can deliver strong cyber command and control without relying on internet connectivity.<\/p>\n\n\n\n

No Single Strategy is 100% Attack Proof<\/h2>\n\n\n\n

Physically or logically isolating networks into air-gapped networks is a sound security strategy that defense, intelligence and civilian agencies employ to prevent access to sensitive or classified systems and operations. Yet their isolation alone is not enough to ensure air-tight security.<\/p>\n\n\n\n

While air-gapping does reduce remote risk, it is not exactly immune to cyber risk. Air-gapped environments are designed to block external adversaries by isolating networks from the internet or a broader enterprise. But that isolation inevitably shifts risk toward the people who do have access\u2014admins, operators, contractors, maintenance staff and trusted vendors. By eliminating one problem, there is often an unintended consequence of risk\u2014by blocking outsiders, threat likelihood from insiders becomes concentrated.<\/p>\n\n\n\n

In most air-gapped environments, a small set of users has elevated access. Patching and updates are slow, and monitoring is limited or entirely local to the air-gapped network. Due to the isolation of the systems, physical presence is required, increasing insider impact. This makes insiders the most capable attack vector\u2014whether through malicious or simply negligent behavior. <\/p>\n\n\n\n

Air-gapped environments make heavy use of Universal Serial Bus (USB), compact disks (CDs), digital versatile disks (DVDs), portable Solid-State Drives (SSDs) and sneakernet to move data from system to system, and to apply updates and patches. This offers the opportunity for tampering, and these environments often lack the continuous monitoring needed to spot and stop these risks, resulting in threat detection gaps and delays.  A mature data protection strategy is vital in air-gapped environments to thwart insider threats.<\/p>\n\n\n\n

Because air gapped systems rely entirely on local security measures, organizations must build layered, robust defenses to secure classified and sensitive assets. Local protection is everything, and for high-risk agencies that means monitoring and securing every single endpoint.<\/p>\n\n\n\n

How Endpoint Protection Fills the Gaps<\/h2>\n\n\n\n

Endpoint protection is a broad term describing technology and strategies used to secure end-user devices, such as laptops, computers and mobile devices. Since these devices get the most direct human interaction while housing vital data, they are exceptionally vulnerable to cyberattacks, even in air-gapped networks. To avoid critical breaches, security operators must be able to detect, prevent and respond to threats on each endpoint device in any given environment, especially when they interact with classified data.<\/p>\n\n\n\n

Many organizations are turning to cloud-native endpoint security solutions that depend upon cloud-based machine learning for anomaly detection. While these endpoint security tools may be suitable for some systems and some environments, they depend on the cloud to function so they cannot operate in disconnected or air-gapped environments. This opens security gaps, leaving devices vulnerable to cyberattacks and insider threats. Security teams can solve this problem by investing in endpoint protection approaches that are well-suited to air-gapped environments, enabling the visibility and control necessary to safeguard these critical systems.<\/p>\n\n\n\n

The Benefits of Customizable Endpoint Protection<\/h2>\n\n\n

The ability to tailor security for nuanced policy control and security monitoring\u2014including specific configurations for user roles, device types or classification levels\u2014is crucial to ensure a strong security posture. Endpoint security solutions must also be established independently from the cloud, to run behavioral analytics even in fully isolated network enclaves.<\/p>\n\n\n\n

When a threat occurs, detailed information is vital to protecting high-value assets, and robust air-gapped endpoint security systems enable rapid identification and threat mitigation while providing analysts with forensic data for investigation. This critical context also informs refinements to tailor and optimize the security approach for the environment\u2019s unique mission.<\/p>\n\n\n\n

Implementing a Zero Trust approach is still vital to reducing threats to air-gapped environments, just as it is in internet-facing networks. Hardening systems by ensuring only trusted software can execute enables the mission but not an attacker.<\/p>\n\n\n\n

Safeguarding the data from insider threats is another important element of a mature air-gapped security operation. Data Loss Prevention (DLP) offers an important countermeasure against cybersecurity risk in air-gapped environments and allows security teams the ability to ensure that organizational data is appropriately controlled. <\/p>\n\n\n\n

Two Industry Leaders, One Unbreakable Line of Defense<\/h2>\n\n\n\n

Defense and intelligence agencies cannot afford to leave gaps from security tooling that is unsuitable to defend disconnected networks and endpoints. They need an endpoint security suite built for their world\u2014one that delivers advanced security capabilities to offline, high-stakes and mission critical IT systems. Symantec and Carbon Black deliver exactly that: proven protection designed for Federal environments.<\/p>\n\n\n\n

Both solutions are purpose-built for Government, but each brings its own strengths to the field:<\/p>\n\n\n\n
