Types of attack. 2.1. Malicious technical attacks: These are intentional attacks which seek to gain access to a school’s system and data. Often, these attacks also attempt to use the school’s system to mount further attacks on other systems, or use the system for unauthorised purposes, and can lead to reputational damage.
Types of attack. In addition to these five specific cheats we introduce two new types of attack which are well-known in the protocol literature [11]. These two types of attacks have significant potential for damaging the security goals of the protocol be- cause they undermine the authentication of the source of a message. • Replay Attacks - The attacker reuses a message previ- ously sent by another player in whole or in part and it is accepted as valid. This can be used to duplicate the move of an opponent without necessarily knowing what the move is. Spoofing Attacks - The attacker can construct messages which appear to be from another player and are ac- cepted as valid. • We will compare the security of the NEO protocol to our improved version, which we call Secure Event Agreement (SEA), based on the five cheats and these additional criteria.
