Tips for difficult areas
The following topics are the ones that seem to be the most difficult for students, so here are some tips to deal with them:
Encryption – Cryptography, Hashing and PKI are difficult areas, but for the exam you will only need basic understanding.
Malicious attacks – There are many types of attacks and it can be difficult to remember them all, so it’s recommended you take extra time learning as many as you can.
Access control models – The three models (Discretionary access control, mandatory control and roll based access control) can be confusing so it is important to know the differences in each model.
Authentication models – there are many types of models for Authentication; from physical to logical and local to remote. So it’s important to remember each type and their differences.
