Snort uses rules and signatures to generate alerts. (Choose two.). Explanation: Confidentiality ensures that data is accessed only by authorized individuals. Traffic from the Internet and LAN can access the DMZ. (Not all options are used. Explanation: After the crypto map command in global configuration mode has been issued, the new crypto map will remain disabled until a peer and a valid access list have been configured. Explanation: Access control refers to the security features. Based on the security levels of the interfaces on ASA1, what traffic will be allowed on the interfaces? 112. What is the main factor that ensures the security of encryption of modern algorithms? A web security solution will control your staff's web use, block web-based threats, and deny access to malicious websites. When a host in 172.16.1/24 sends a datagram to an Amazon.com server, the router \ ( \mathrm {R} 1 \) will encrypt the datagram using IPsec. Immediately suspend the network privileges of the user. ), 69. For example, Forcepoint's Next Generation Firewall (NGFW) offers seamless and centrally managed control of network traffic, whether it is physical, virtual or in the cloud.

A. Both IDS and IPS can use signature-based technology to detect malicious packets. What service provides this type of guarantee? Secure IPS appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection. Each network security layer implements policies and controls. What are two drawbacks to using HIPS? Using an out-of-band communication channel (OOB) either requires physical access to the file server or, if done through the internet, does not necessarily encrypt the communication. How the network resources are to be used should be clearly defined in a (an) ____________ policy. Explanation: The IPsec framework consists of five building blocks. To ensure that potential attackers cannot infiltrate your network, comprehensive access control policies need to be in place for both users and devices. The least privileges principle of cyber security states that no rights, access to the system should be given to any of the employees of the organization unless he/she needs those particular rights, access in order to complete the given task. Ideally, the classifications are based on endpoint identity, not mere IP addresses. An IPS provides more security than an ***A virus is a program that spreads by replicating itself into other programs or documents. 12) Which one of the following refers to the technique used for verifying the integrity of the message?

In short, we can say that its primary work is to restrict or control the assignment of rights to the employees. Explanation: OOB management provides a dedicated management network without production traffic. Of course, you need to control which devices can access your network. Which type of firewall makes use of a server to connect to destination devices on behalf of clients? This set of following multiple-choice questions and answers focuses on "Cyber Security". The username and password would be easily captured if the data transmission is intercepted. It combines authentication and authorization into one process; thus, a password is encrypted for transmission while the rest of the packet will be sent in plain text. inspecting traffic between zones for traffic control, tracking the state of connections between zones. 44.

Use ISL encapsulation on all trunk links. 6. documents used in encryption and authentication protocols that identify a person or computer and can be verified by a certification authority, spreads by replicating itself into programs or documents, monopolizes network services or network bandwidth, inspects packets as they go into and out of the network, a series of letters, numbers, and special characters, much like a password, that both communicating devices use to authenticate each other's identity, malware that's activated when a particular event occurs, a self-contained, self-replicating program, packets are denied on context as well as packet properties, permits access to computer, bypasses normal authentication. This section focuses on "Network Security" in Cyber Security. The code is authentic and is actually sourced by the publisher. Match the security technology with the description. 24. What is the effect of applying this access list command? 58. This means that the security of encryption lies in the secrecy of the keys, not the algorithm. The code was encrypted with both a private and public key. An IDS uses signature-based technology to detect malicious packets, whereas an IPS uses profile-based technology. Explanation: Stateful firewalls cannot prevent application layer attacks because they do not examine the actual contents of the HTTP connection. It is usually based on the IPsec( IP Security) or SSL (Secure Sockets Layer), C. It typically creates a secure, encrypted virtual tunnel over the open internet. A. Authentication 72.
