When describing malware, what is a difference between a virus and a worm? Select one: A. D. All of the above. Tripwire is used to assess if network devices are compliant with network security policies. 92. Both devices use an implicit deny, top down sequential processing, and named or numbered ACLs. It is also known as the upgraded version of the WPA protocol. This provides a user with unlimited attempts at accessing a device without causing the user account to become locked and thus requiring administrator intervention. RADIUS supports remote access technology, such as 802.1x and SIP; TACACS+ does not. D. Neither A nor B. Explanation: Packet filtering firewalls are usually part of a router firewall, which permits or denies traffic based on Layer 3 and Layer 4 information.An application gateway firewall (proxy firewall), as shown in the figure, filters information at Layers 3, 4, 5, and 7 of the OSI reference model. One has to deploy hardware, software, and security procedures to lock those apps down. In addition, an interface cannot be simultaneously configured as a security zone member and for IP inspection., 43.

UserID can be a combination of username, user student number etc. Gain unified segmentation of workloads: a single pane of glass from the workload to the network and cloud, supporting all workload types without limitations. D. Scalar text. The firewall will automatically allow HTTP, HTTPS, and FTP traffic from g0/0 to s0/0/0, but will not track the state of connections. The analyst has just downloaded and installed the Snort OVA file. Which two statements describe the effect of the access control list wildcard mask 0.0.0.15? Place extended ACLs close to the source IP address of the traffic. ***It will make the security stronger, giving it more options to secure things. (Not all options are used. Disabling the Spanning Tree Protocol (STP) will not eliminate VLAN hopping attacks. Now let's take a look at some of the different ways you can secure your network. Which two steps are required before SSH can be enabled on a Cisco router? RADIUS provides encryption of the complete packet during transfer. Cisco IOS ACLs are processed sequentially from the top down and Cisco ASA ACLs are not processed sequentially. 9. 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. Which three statements are generally considered to be best practices in the placement of ACLs? Explanation: Packet Filtering (Stateless) Firewall uses a simple policy table look-up that filters traffic based on specific criteria and is considered the easiest firewall to implement. RSA is an algorithm used for authentication. It also provides many features such as anonymity and incognito options to insure that user information is always protected.

The four major parts of the communication process are the ___, the ___, the ___, and ___. Explanation: Traffic originating from the public network and traveling toward the DMZ is selectively permitted and inspected. Both IDS and IPS can use signature-based technology to detect malicious packets. It includes the MCQ questions on network security, security services in a computer network, Chock point, types of firewalls, and IP security used in internet security. C. You need to employ hardware, software, and security processes to lock those apps down. Second, generate a set of RSA keys to be used for encrypting and decrypting the traffic. 33) Which of the following is considered as the world's first antivirus program? It is an important source of the alert data that is indexed in the Sguil analysis tool. Which statement describes an important characteristic of a site-to-site VPN? It indicates that IKE will be used to establish the IPsec tunnel for protecting the traffic. 9) Read the following statement carefully and find out whether it is correct about the hacking or not? ACLs are used primarily to filter traffic. Explanation: CHAP stands for Challenge Handshake authentication protocol. Within the next three years, 90 percent of IT organizations may support corporate applications on personal mobile devices. This means that the security of encryption lies in the secrecy of the keys, not the algorithm. HMAC uses a secret key as input to the hash function, adding authentication to integrity assurance. A company is concerned with leaked and stolen corporate data on hard copies. 24) Which one of the following is also referred to as malicious software?
