Exam 16: Security

User authentication can be based on_______________

MS Word documents in RTF format are resistant to macro viruses.

It is much faster for a computer to encode and decode ciphertext by using the usual symmetric algorithms than by using asymmetric algorithms.

In a symmetric encryption algorithm, one key is used to encrypt and a different one is used to decrypt.

How are one-time password systems implemented?

Vulnerability scans can check:

________________ encrypts the information on the target computer and renders it inaccessible to the owner

A firewall is installed between the trusted and the untrusted.

Port scanning allows a hacker to__________________

To protect the systems we have to ensure security on the following level:

TLS provides security at the _______ layer.

When a user logs on, MW Windows 10 creates a list of files which can be used by the user.

Why an asymmetric encryption algorithm uses two keys?

Transport Layer Security (TLS) employs server's certificate from certification authority (CA).

______________ virus changes each time it is installed to avoid detection by antivirus software.

Describe the idea of masquerading attack.

What does a security policy include?

The attack surface is the set of points at which an attacker can try to break into the system.

What is the reason to use a stream cipher?

Describe the problem of a buffer overflow.
