What is statistical data network security?
They are developing data science techniques that will allow dynamic computer networks to detect intrusions and anomalous behavior, preventing them from being attacked via cyber weapons.
Which two options are network security monitoring approaches that use advanced analytic techniques to analyze network telemetry data choose two?
Described as analytics techniques for the analysis of NetFlow and IPFIX telemetry data, networking behavior analysis (NBA) and network behavior anomaly detection (NBAD) are approaches to network security monitoring.
Which statement describes an operational characteristic of NetFlow group of answer choices?
What is characteristic of NetFlow? Data flow itself is not captured by NetFlow. The data is collected through a series of metadata about the flow.
Which Windows log records events related?
Log files kept by Windows hosts document security events, such as login attempts or files or objects managed or accessed.
What is network security monitoring?
The purpose of Network Security Monitoring is to collect, analyze, and escalate indications and warnings about possible network intrusions so that you can detect and prepare for them. Monitors of network security typically include the following features. Querying security data and/or hunting for suspicious behavior by actively searching the network.
What are the four types of network security?
The right to access the system. Software used to detect and prevent malware, such as antivirus and antispyware. The security of application code... A behavioral analytics approach. ... prevent data loss by taking the necessary steps. A method to prevent distributed denial of service attacks. A few words about email security... There are firewalls.
What is the difference between data security and network security?
Information SecurityNetwork SecurityIt deals with the protection of data from any form of threat.It deals with the protection from DOS attacks.
What are examples of network security?
In addition to access control and virus scanning software, network security also involves application security, network analytics, and other types of network-related security (endpoint, web, wireless), firewalls, and VPN encryption.
How is statistical data used in network security monitoring processes?
Statistical data are collected in the monitoring process of network security. Network hosts are able to communicate with one another using it. In this case, it shows how network activities have been distributed between networks. Data about other types of networks is analyzed to determine its composition.
How can Nat Pat complicate network security monitoring If NetFlow is being used?
What are the implications of NAT/PAT for g if NetFlow is being used? MAC addresses are changed at both origin and destination. Data packet payloads are encrypted so that the packet's content can be hidden. A user is able to disguise an application starting from a port by manipulating the port.
What information is provided by the Cisco NetFlow utility?
What information can the Cisco NetFlow utility provide? ? Network traffic accounting as well as usage-based network billing, network planning, security, and denial of service monitoring capabilities are few of the most important services that NetFlow provides for IP applications.
Which Windows host log event type describes the successful operation of an application driver or service group of answer choices?
In the Information event type, an event is recorded when an app, driver, or service runs successfully.
Which two technologies are used in the enterprise log search and archive Elsa tool choose two?
The ELSA tool utilizes two different technologies. Two of these options should be chosen. This tool allows for searching and archiving of NSM data generated from multiple sources. It is a multi-user enterprise-level application. Sphinx Search is used to index ELSA logs. Logs are received over Syslog-NG, stored in MySQL databases, and indexed using Syslog-NG.
Which of the following classify an alert that correctly identifies an exploit has occurred?
An alert that correctly identifies an exploit uses what classification? ? In the case of an IDS or IPS signature that is triggered correctly and an alarm generated when offending traffic is detected, that is a true positive.
Which protocol is used to send e mail messages between two servers that are in different email domains?
When sending e-mail between two servers in different e-mail domains, which protocol is used? ? An explanation of what SMTP is: SMTP is designed to help send messages between mail servers, or to send messages from one server to another.
What is the tool that has Alert records linked directly to the search functionality of the enterprise log search and archive Elsa )?
This Enterprise Log Search and Archive (ELSA) tool allows you to search and archive the NSM log data at the enterprise level. The search functionality in ELSA is directly linked to the functionality in Sguil, so pivoting from one to the other allows you to conduct searches.
How is optional network layer information carried by IPv6 packets?
The IPv6 network layer carries optional info in packets. A extension header specifies information that can be sent at the network layer in IPv6. Headers for extension are separate headers that go between each IPv6 header and the payload, not part of the main header.
