QUESTION 1:

A malicious program is disguised as another useful program; consequently, when the user executes the program, files get erased and then the malicious program spreads itself using emails as the delivery mechanism. Which type of attack best describes how this scenario got started?

A. DoS B. worm C. virus
D. trojan horse
E. DDoS Answer: D
Explanation:
Denial of Service (DoS) is an attack designed to render a computer or network incapable
of providing normal services. The most common DoS attacks will target the computer’s network bandwidth or connectivity. Bandwidth attacks flood the network with such a
high volume of traffic, that all available network resources are consumed and legitimate user requests cannot get through. Connectivity attacks flood a computer with such a high volume of connection requests, that all available operating system resources are
consumed and the computer can no longer process legitimate user requests.
A “denial-of-service” attack is characterized by an explicit attempt by attackers to prevent legitimate users of a service from using that service. Examples include
* attempts to “flood” a network, thereby preventing legitimate network traffic
* attempts to disrupt connections between two machines, thereby preventing access to a service
* attempts to prevent a particular individual from accessing a service
* attempts to disrupt service to a specific system or person
Distributed Denial of Service
* An attacker launches the attack using several machines. In this case, an attacker breaks into several machines, or coordinates with several zombies to launch an attack against a target or network at the same time.
* This makes it difficult to detect because attacks originate from several IP addresses.
* If a single IP address is attacking a company, it can block that address at its firewall. If
it is 300 00 this is extremely difficult.

QUESTION 2:

What is the key function of a comprehensive security policy?

A. informing staff of their obligatory requirements for protecting technology and information assets
B. detailing the way security needs will be met at corporate and department levels

642-552

C. recommending that Cisco IPS sensors be implemented at the network edge
D. detailing how to block malicious network attacks
Answer: A Explanation:
Developing a strong security policy helps to protect your resources only if all staff members are properly instructed on all facets and processes of the policy. Most companies have a system in place whereby all employees need to sign a statement confirming that they have read and understood the security policy. The policy should cover all issues the employees encounter in their day-to-day work, such as laptop security, password policy, handling of sensitive information, access levels, tailgating, countermeasures, photo IDs, PIN codes, and security information delivered via newsletters and posters. A top-down approach is required if the policy is to be taken seriously. This means that the security policy should be issued and supported from an executive level downward.

QUESTION 3:

Which building blocks make up the Adaptive Threat Defense phase of Cisco SDN
strategy?

A. VoIP services, NAC services, Cisco IBNS
B. network foundation protection, NIDS services, adaptive threat mitigation services
C. firewall services, intrusion prevention, secure connectivity
D. firewall services, IPS and network antivirus services, network intelligence
E. Anti-X defense, NAC services, network foundation protection
Answer: D Explanation:
Computer connected to the Internet without a firewall can be hijacked and added to an Internet outlaw’s botnet in just a few minutes. A firewall can block malware that could otherwise scan your computer for vulnerabilities and then try to break in at a weak point. The real issue is how to make one 99.9% secure when it is connected to in Internet. At a minimum computers need to have firewall, antivirus and anti-spyware software installed and kept up-to-date. A home network that uses a wired or wireless router with firewall features provides additional protection.
A computer virus can be best described as a small program or piece of code that
penetrates into the operating system, causing unexpected and negative events to occur. A well-known example is a virus, SoBig. Computer viruses reside in the active memory of the host and try to duplicate themselves by different means. This duplication mechanism can vary from copying files and broadcasting data on local-area network (LAN) segments
to sending copies via e-mail or an Internet relay chat (IRC). Antivirus software
applications are developed to scan the memory and hard disks of hosts for known viruses.

If the application finds a virus (using a reference database with virus definitions), it
informs the user.

QUESTION 4:

DRAG DROP
You work as a network administrator at Certkiller .com. Your boss Mrs. Certkiller asks you to match the malicious network attack types with the correct definition.
