Monitoring-as-a-service (MaaS) is a cloud delivery model that falls under anything as a service (XaaS). MaaS allows for the deployment of monitoring functionalities for several other services and applications within the cloud. 

Answer: C 

Explanation: 

RDP uses TCP port 3389. 

Answer: D 

Explanation: 

We can see a number of unsuccessful login attempts using a Remote Desktop Connection (using the RDP protocol) from a computer with the IP address 192.168.1.124. Someone successfully logged in locally. This is probably an authorized login (for example, Joe logging in). Hardening is the process of securing a system. We can harden (secure) the system by either disallowing remote desktop connections altogether or by restricting which IPs are allowed to initiate remote desktop connections. 

Answer: D 

Explanation: 

Port security in IT can mean several things: The physical control of all connection points, such as RJ-45 wall jacks or device ports, so that no unauthorized users or unauthorized devices can attempt to connect into an open port. The management of TCP and User Datagram Protocol (UDP) ports. If a service is active and assigned to a port, then that port is open. All the other 65,535 ports (of TCP or UDP) are closed if a service isn’t actively using them. Port knocking is a security system in which all ports on a system appear closed. However, if the client sends packets to a specific set of ports in a certain order, a bit like a secret knock, then the desired service port becomes open and allows the client software to connect to the service. 

Answer: A 

Explanation: 

Peer-to-peer (P2P) networking is commonly used to share files such as movies and music, but you must not allow users to bring in devices and create their own little networks. All networking must be done through administrators and not on a P2P basis. Data integrity can easily be compromised when using public P2P networking. 

Answer: D 

Explanation: 

Routine audits are carried out after you have implemented security controls based on risk. These audits include aspects such as user rights and permissions and specific events. 

Answer: D 

Explanation: 

SSH uses TCP port 22. All protocols encrypted by SSH, including SFTP, SHTTP, SCP, SExec, and slogin, also use TCP port 22. 

Answer: C 

Explanation: 

Since a user’s password isn’t stored on most operating systems (only a hash value is kept), most operating systems allow the administrator (or authorized person in this case) to change the value then the information/files/documents can be accessed. This is the safest way of recovery by an authorized person and is not dependent on those who leave the firm. 

Answer: C 

Explanation: 

A corrective control would be any corrective action taken to correct any existing control that were faulty or wrongly installed – as in this case the cameras were already there, it just had to be adjusted to perform its function as intended. 

Answer: C 

Explanation: 

A bluejacking attack is where unsolicited messages are sent to mobile devices using Bluetooth. Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i.e., for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol. Bluetooth has a very limited range, usually around 10 metres (32.8 ft) on mobile phones, but laptops can reach up to 100 metres (328 ft) with powerful (Class 1) transmitters. Bluejacking is usually harmless, but because bluejacked people generally don't know what has happened, they may think that their phone is malfunctioning. Usually, a bluejacker will only send a text message, but with modern phones it's possible to send images or sounds as well. Bluejacking has been used in guerrilla marketing campaigns to promote advergames.
