Access Control Systems: Security, Identity Management and by Messaoud Benantar

By Messaoud Benantar

No longer a lot to claim in this booklet other than that i discovered it incomplete and missing in sensible tactics, extra studious than program orientated. i've got learn greater books at the topic just like the IAM luck tips: quantity 1 which deals much more strategical info because it is extra of a advisor than a tutorial learn.

Auditing is starting to take a different shape in recent years, that of vulnerability assessment and intrusion detection or prevention. Intrusion prevention attempts to predict security incidents and attacks before they take place. Auditing is a key security element of systems and networks. It maintains evidence of attempts to compromise the security controls put in place by an organization. Furthermore, audits that are regularly performed can be used to determine system and resource usage and to identify the parties involved.

Recall that acting on behalf of an entity implies the use of that entity's security context and hence its identity and entitlements. Masquerading under someone's identity, however, is a security violation. The key distinction between delegation and masquerading is that delegation implies the presence of two entities both of which are aware of one another and one is consenting that the other assumes its identity. Masquerading, on the other hand, happens when an entity assumes the identity of another entity without explicit or implicit consent.

Brute-force attacks that do not depend on a prebuilt dictionary can be used to crack encoded passwords as well. A minute change in the input of a one-way digest algorithm yields a different digest. The salt is a value that is incorporated into the calculation of the password transform to thwart dictionary attacks. By digesting the password with a salt, a dictionary attack becomes harder to achieve. The attacker needs to search through the entire dictionary for each value of the salt. Pseudo-random generation of salt values makes them harder to guess.
