Advantages |
Disadvantages |
| 1 |
Anti-virus Trust level Healthy-Danger-Infected (ATHDI) |
Improved model that includes anti-virus program and trust- level of user |
More factors are considered for propagation analysis |
Impossible to detect the presence of email before the receivers receive the email |
| 2 |
Susceptible-Exposed-Infectious-Recovered |
Virus propagation is faster while users login in their accounts more frequently. |
Indicate the effects of the networks and users on SNS network. |
Assess of the anti-virus strategy is low. |
| 3 |
ACT Scheme |
Propagation of the virus in the network is controlled by identifying the existence of the transmission chain in the network. |
It uses the contact list tracing to find the epidemiological links between host |
Limited to single enterprise, where it is possible to collect all necessary traffic information in a casual chain. |
| 4 |
Susceptible-Infected- Removed (SIR) |
Dynamic propagation of email virus was approximated for homogeneous network. |
Used in email and social network. |
Not suitable for heterogeneous network. |
| 5 |
Susceptible-Infected- Immunized (SII) |
This model is able to address two critical processes such as reinfection and self-start that is unsolved in the previous models. |
Avoid systems threats before infected by virus. |
Independent assumption and periodic assumption are unsolved problems |
