The Record Protocol within SSL provides:

Transaction’s non-repudiation

Message confidentiality

Message integrity

Authentication of entities

S/MIME provides protection against:

Unauthorized message alteration

E-mail addresses substitution

Virus multiplication

Denial-of-service attacks

Which are the main advantages of virtual private networks (VPN) in comparison with frame relay based networks, leased lines or dial-up?

Lower installation and operation costs

Increasing security level

Higher availability for network services

Higher transfer rates

The “data tunneling” expression, specific to VPNs it refers to:

Method used by system administrators for detecting possible network intrusions

A mechanism which allow data to pass through firewall systems

Optional feature which activated, increases the network performances

Packet encapsulation in other packages belonging to a different protocol in order to create a virtual circuit

Which is the SSL protocol used for entities authentication and the negotiation of algorithms and cryptographic keys:

Change Cipher SpecProtocol

Internet Key Exchange

Record Protocol

Handshake Protocol

Who developed the X.509 standard, describing the digital certificates syntax?

International Telecommunication Union (ITU)

Internet Engineering Task Force (IETF)

International Standards Organization (ISO)

RSA Laboratories

How is the session key generated within the Diffie Helman protocol?

The session key is generated by exchanging random values between transmitter and recipient and the use of an algorithm whose security is based on the impossibility of calculating discrete logarithms

The session key is randomly generated by the transmitter and sent encrypted to the recipient

The session key is generated by a third trustful party

The session key is generated simultaneously by transmitter and recipient using a time based algorithm

In which of the following authentication protocols mentioned below, the password is transmitted in clear through the network?

Password Authentication Procedure (PAP)

Kerberos

Challenge-Handshake Authentication Protocol (CHAP)

Windows NT LAN Manager (NTLM)

Kerberos is efficient against the following:

Dictionary attacks

Repetition attacks

Denial-of service attacks

Social engineering

Which of the following technologies uses two factors for the authentication of its users?

SAKMP/Oakley

NTLM

LDAP

RSA SecurID

The Encapsulating Security Payload (ESP) protocol within IPSec provides:

Data origin authentication

Data integrity

Data confidentiality

Data non-repudiation transfer

Which of the following sentences about the standard PKCS #7 are true?

It uses the ASN.1 language for describing the data structures

It specifies the syntax for cryptographic messages

It became outdated, being replaced by the PKCS #8 standard

Have been developed by the Internet Engineering Task Force (IETF)

Which of the following affirmations about the SSL protocol are true?

It uses digital certificates for parties authentication

Is a third level protocol

It can only be used for securing the web traffic

It requires changing the TCP/IP stack

Which of the following affirmations about the Kerberos protocol are true?

It represents the main authentication mechanism in Windows 2000/2003/2008 domains

Has been developed by RSA Security corporation

Is time dependent

Which of the following organizations deals with the standardization of electronic signature at European level?

ETSI ESI

ISO/IEC

PC/SC

CEN/ISSS

What are the main advantages of the web of trust model used by PGP to establish trust in a public key:

Transitivity of trust relationships

High scalability

Doesn’t need a third trustful entity

Avoids the necessity of key revocation if the key was compromised

What needs to be used for encrypting and signing the electronic messages using S/MIME?

S/MIME compatible e-mail servers

S/MIME compatible e-mail clients

SSLization of e-mail servers and clients

Digital certificates for users
