Abstract: A technique to improve security for a VLAN is disclosed. A security appliance is set as the gateway for intra-LAN communication. Message traffic is analyzed and anomalies are detected relative to normal message traffic that correspond to device health problems that may require service by a field technician. A network switch may be configured to drop certain types of Address Resolution Protocol messages from selected ports to aid in setting a security appliance as the gateway.

Abstract: A technique to stop lateral movement of ransomware between endpoints in a VLAN is disclosed. A security appliance is set as the default gateway for intra-LAN communication by overwriting the DHCP responses. Message traffic from compromised endpoints is detected. Attributes of ransomware may be detected in the message traffic, as well as attempts to circumvent the security appliance. Compromised devices may be quarantined. Additionally, the DHCP address assignment may be policed to ensure accuracy and correctness to provide an additional layer of security.

Abstract: An extended browser provides additional protection against lateral propagation of ransomware to an endpoint device. The extended browser may monitor for inbound connection requests having access protocols vulnerable to ransomware attacks. The extended browser may select a certificate provided to an identity provider based on the ransomware threat level based at least in part on the detection of connection requests having access protocols vulnerable to ransomware attacks. Access to SaaS or private enterprise application may be limited or denied in response to detecting connection requests having the vulnerable access protocols. The endpoint device may also be part of a VLAN with endpoint device deployed under a default gateway with point-to-point links.

Abstract: An extended enterprise browser provides protection from ransomware attacks against SaaS and private enterprise application. In one implementation, the extended enterprise browser supports at least two different endpoint security certificates. A selection of the endpoint security certificate is made based on a ransomware risk level posture. Various factors may be used to determine the ransomware risk level posture to aid preventing ransomware attacks.

Abstract: A system and method for ransomware protection includes an extended browser in an endpoint device. The extended browser selects a certificate for user authentication with an identity provider based on the enterprise ransomware threat level. The selection of the certification may be used to aid in providing protection from ransomware attacks of SaaS and private enterprise applications. The endpoint device may be part of a larger VLAN environment in which endpoint devices are deployed under a default gateway with point-to-point links.

Abstract: An extended enterprise browser installed on an endpoint device provides protection from ransomware attacks to SaaS and private enterprise applications. The extended enterprise browser monitors for alternate browser installed on the endpoint device. The extended enterprise browser may take one or more actions to block the spread of ransomware by the alternate browser.

Abstract: An extended enterprise browser supports using at least two different authentication certificates depending on factors such as a ransomware risk posture. Secure user access may be provided by using a trusted platform module to encrypt/decrypt the authentication certificates based on a secret key generated based on information from the trusted platform module and the extended enterprise browser. Man-in-the Middle (MITM) attacks of the authentication certificated by ransomware is prevented.

Abstract: A technique to stop lateral movement of ransomware between endpoints in a VLAN is disclosed. A security appliance is set as the default gateway for intra-LAN communication by overwriting the DHCP responses. Message traffic from compromised endpoints is detected. Attributes of ransomware may be detected in the message traffic, as well as attempts to circumvent the security appliance. Compromised devices may be quarantined. The security appliance may act in response to an initial detection of ransomware such that it does not ordinarily interfere with operation of a primary DHCP server.

Abstract: A technique to stop lateral movement of ransomware between endpoints in a VLAN is disclosed. The security appliance may be implemented on-prem or in cloud data center environments. A security appliance is set as the default gateway for intra-LAN communication. Message traffic from compromised endpoints is detected. Attributes of ransomware may be detected in the message traffic, as well as attempts to circumvent the security appliance. Compromised devices may be quarantined.

Abstract: Provided are systems, methods, and computer-program products for deception mechanisms in a containerized environment. In various implementations, a deception platform can detect the configuration of a containerized environment, including namespaces, services, and configuration of the environment. The deception platform can determine appropriate decoy containerized services for the environment, and can deploy the decoy alongside production containerized service. The deception platform can further determine decoy breadcrumbs for luring attackers to the decoy containerized service. The decoy breadcrumbs can be injected into the environment at locations where an attacker will look for information for further infiltrating the environment. The deception platform can then monitor the decoy containerized service for unexpected accesses.

Abstract: A method for performing peripheral failover includes the steps of identifying a virtual device associated with a first slot of a plurality of slots, identifying a backup I/O component in a second slot of the plurality of slots, and disassociating the virtual device with the first slot and associating the virtual device with the second slot.
