Checkpoint 156-215.81 Actual Questions

 In Security Gateways R75 and above, SIC uses AES-128 for encryption. SIC stands for Secure Internal Communication, which is a mechanism that establishes trust between Check Point components, such as Security Gateways, Security Management Servers, Log Servers, etc. SIC uses certificates to authenticate and encrypt the communication between the components. AES-128 is an encryption algorithm that uses a 128-bit key to encrypt and decrypt data. The other options are incorrect. AES-256 is an encryption algorithm that uses a 256-bit key, but it is not used by SIC. DES and 3DES are older encryption algorithms that use 56-bit and 168-bit keys respectively, but they are not used by SIC either.

The User Directory is used to obtain identification and security information about network users. It can be integrated with external user databases such as LDAP, RADIUS, or TACACS+. References: Certified Security Administrator (CCSA) R81.20 Course Overview, page 9.

LDAP (Lightweight Directory Access Protocol) is a protocol that allows accessing and maintaining distributed directory information services over a network. User Directory integration is a feature of Identity Awareness that allows Check Point products to use LDAP servers as identity sources. When configuring LDAP with User Directory integration, changes applied to a User Directory template are reflected immediately for all users who are using that template. A User Directory template defines the settings for connecting to an LDAP server and retrieving user information3.

 Identity Awareness is a blade that enables administrators to define access rules based on the identity of users and machines, rather than just IP addresses. Identity Awareness allows easy configuration for network access and auditing based on three items: network location, the identity of a user, and the identity of a machine. Network location refers to the source or destination network segment of the traffic. The identity of a user refers to the username or group membership of the user who initiates or receives the traffic. The identity of a machine refers to the hostname or certificate of the machine that initiates or receives the traffic. References: [Check Point R81 Identity Awareness Administration Guide]
