Multi-factor deception management and detection for malicious actions in a computer network
A network surveillance system, including a management server within a network of resources in which users access the resources in the network based on credentials, including a deployment module planting honeytokens in resources in the network, wherein a honeytoken is an object in memory or storage of a first resource that may be used by an attacker to access a second resource using decoy credentials, and wherein the deployment module plants a first honeytoken in a first resource, R 1 , used to access a second resource, R 2 , using first decoy credentials, and plants a second honeytoken in R 2 , used to access a third resource, R 3 , using second decoy credentials, and an alert module alerting that an attacker is intruding the network only in response to both an attempt to access R 2 using the first decoy credentials, and a subsequent attempt to access R 3 using the second decoy credentials.
1. A system for multi-factor network surveillance to detect attackers, comprising:
a management server within a network of resources in which users access the resources based on credentials, comprising a memory containing instructions and a processor that executes the instructions to plant decoy credentials DC 1 , DC 2 , and DC 3 , in memory or storage of respective resources R 1 , R 2 and R 3 , wherein the decoy credentials DC 1 DC 2 and DC 3 may be used by an attacker to access respective resources R 2 , R 3 and R 4 , and wherein R 1 is a bona fide enterprise resource, and R 2 , R 3 and R 4 are decoy resources for the purpose of intrusion detection; and
a security manager comprising a memory containing instructions and a processor that executes the instructions to receive reports of attempts to use decoy credentials and to generate an alert that an attacker is intruding the network only when attempts to use the three decoy credentials DC 1 DC 2 and DC 3 are reported.
2. The system of claim 1 wherein credentials include passwords for accessing resources in the network, and wherein the decoy credentials include respective hash versions of corresponding passwords.
3. The system of claim 1 wherein credentials include members of the group consisting of user credentials, FTP server credentials and SSH server credentials.
4. A system for multi-factor network surveillance to detect attackers, comprising:
a management server within a network of resources, comprising a memory containing instructions and a processor that executes the instructions to plant honeytokens HT 1 HT 2 and HT 3 in respective resources R 1 , R 2 and R 31 wherein honeytokens HT 1 HT 2 and HT 3 are objects in memory or storage of R 1 , R 2 and R 3 , respectively, that may be used by an attacker to discover existence of R 2 , R 3 and R 4 , respectively, and wherein R 1 is a bona fide enterprise resource and R 2 , R 3 and R 4 are decoy resources for the purpose of intrusion detection; and
a security manager comprising a memory containing instructions and a processor that executes the instructions to receive reports of attempts to access resources, and to generate an alert that an attacker is intruding the network only when attempts to access the three resources R 2 , R 3 and R 4 are reported.
