In the context of malicious attacks, intrusion tolerance [10, 27] goes beyond traditional fault tolerance.
We instead follow a high level approach and, focusing on a context of malicious attack, base our estimates on simple and conservative modeling decisions: intrusions cannot be detected and any number of intrusions above the threshold implies immediate failure.
Instead, they claim malicious intent, react without context, and then turn their device into a weapon of pinpointed destruction.
In a recent work, Královič and Miklík (SIROCCO 2010, LNCS 6058, pp. 157 167) [20] considered various types of malicious host behavior in the context of the Periodic Data Retrieval problem in asynchronous ring networks with exactly one malicious host.
A single slip-up, to them, warrants the dismantling of an entire organization -- just as the appearance of a couple of bad apples in a malicious, heavily edited, out-of-context amateur video was grounds for taking apart ACORN (the real reason being that ACORN was instrumental in getting a lot of Democratic voters to the polls).
A smart malicious node may misbehave in the context of one network function and behave properly for other network functions.
A trust of a malicious node M misbehaving in the context of one of the trust attribute must be decremented as per the specification of MATF.
A security threat in this context is represented by malicious end-users, who attack the confidentiality or integrity of digital assets, in detriment to digital asset creators and/or other end-users.
This update supports a context-aware learning process for malicious insider detection.
At Trust InAdsorg, we often talk about "bad ads" in the context of those that are fraudulent or malicious (e.orgads promoting counterfeit goods, online scams, etc).
