15. Non-transitory computer storage comprising instructions for causing one or more computing devices to share security information by: receiving security attack data from a first entity, the security attack data comprising information regarding one or more security attacks detected by the first entity, wherein an access control list is associated with at least a portion of the security attack data, the access control list indicating respective one or more entities permissioned to receive the portion of security attack data; transmitting the portion of security attack data to respective one or more entities, wherein said transmitting of the portion of security attack data to respective one or more entities is in accordance with the access control list; receiving a ruleset from a second entity, the ruleset based at least in part on the security attack data from the first entity, wherein the ruleset be comprises code instructions executable by a plurality of entities to detect one or more security attacks, and wherein execution of the code instructions of the ruleset identifies malicious behavior of one or more security attacks, and wherein execution of the code instructions of the ruleset accesses one or more data objects associated with respective entities to identify the malicious behavior associated with the respective entities, the one or more data objects comprising at least one of IP address data, proxy data, user login data, malware data, virtual private network data, hostname data, data associated with computing device behavior, or network data, and wherein the ruleset is associated with a ruleset access control list, the ruleset access control list indicating respective one or more entities permissioned to receive the ruleset; and transmitting the ruleset to respective one or more entities, wherein said transmitting of the ruleset to respective one or more entities is in accordance with the ruleset access control list.
15. Non-transitory computer storage comprising instructions for causing one or more computing devices to share security information by: receiving security attack data from a first entity, the security attack data comprising information regarding one or more security attacks detected by the first entity, wherein an access control list is associated with at least a portion of the security attack data, the access control list indicating respective one or more entities permissioned to receive the portion of security attack data; transmitting the portion of security attack data to respective one or more entities, wherein said transmitting of the portion of security attack data to respective one or more entities is in accordance with the access control list; receiving a ruleset from a second entity, the ruleset based at least in part on the security attack data from the first entity, wherein the ruleset be comprises code instructions executable by a plurality of entities to detect one or more security attacks, and wherein execution of the code instructions of the ruleset identifies malicious behavior of one or more security attacks, and wherein execution of the code instructions of the ruleset accesses one or more data objects associated with respective entities to identify the malicious behavior associated with the respective entities, the one or more data objects comprising at least one of IP address data, proxy data, user login data, malware data, virtual private network data, hostname data, data associated with computing device behavior, or network data, and wherein the ruleset is associated with a ruleset access control list, the ruleset access control list indicating respective one or more entities permissioned to receive the ruleset; and transmitting the ruleset to respective one or more entities, wherein said transmitting of the ruleset to respective one or more entities is in accordance with the ruleset access control list. 17. The non-transitory computer storage of claim 15 , further comprising: redacting a portion of the ruleset from the second entity based on preferences of the second entity, such that the redacted portion is not detectable in the ruleset.
