Mandatory access control is access control policies that are decided by the system and not the application or data owner. Mandatory Access Control (MAC) is a group of security policies constrained according to system classification, configuration and authentication. MAC policy management and settings are created in one secure network and defined to system administrators.MAC defines and provides a centralized enforcement of confidential security policy parameters. Mandatory access control creates strict security policies for single users and the resources, systems, or data they are enabled to access. These policies are controlled by a management; single users are not given the authority ... Read More
Access Control is an approach of security that controls access both physically and virtually unless authentication credentials are supported. Access control generally defined restricting physical access to a facility, building or room to authorized persons. This can be used to be enforced generally through a physical security guard.An Access Control system generally involves locked gates, doors or barriers which can be opened using identity authentication approaches such as RFID access cards, pin codes, face recognition, finger prints or smartphones to enable entry to a building or specific area.Access control includes data and physical access protections that strengthen cybersecurity by handling ...

Visitor management is any procedure that provides an organization maintain track of the people that visit their areas. Policies can vary by organization, facility type, industry, or geographic areas.For several organizations, simply collecting the visitor’s name is adequate, but others have larger security requirements such as badges, legal files, employee escorts, and more.Visitor management systems are tools that provide organizations generate or carry out their visitor management policies. As organisation realize the value of visitor management, some are updating from the paper and pen sign-in sheet to a digital visitor management system that can support them do much more.Visitor management ...

There are several types of intrusion prevention system which are as follows −Host-based IPS (HIPS) − A host-based IPS is one where the intrusion-prevention application is local on that specific IP address, generally on a single device. HIPS compliments traditional finger-print-based and heuristic anti-virus detection approaches, because it does not need continuous upgrades to stay ahead of new malware.A comprehensive use of system resources can be a disadvantage of current HIPS, which integrate firewall, system-level action control and sandboxing into a coordinated disclosure net, on top of a traditional AV product.This extensive protection designs can be warranted for a laptop ...

An Intrusion Prevention System is a network security device that monitors network and system activities for malicious or unwanted behavior and can react to block or avoid those activities.Network-based IPS will work in-line to monitor all network traffic for malicious program or attacks. When an attack is identified, it can drop the offending packets while still enabling all other traffic to pass. Intrusion prevention technology is treated by some to be a development of intrusion detection (IDS) technology.Intrusion Prevention Systems (IPS) derivative in the late 1990s to resolve ambiguities in passive network monitoring by locating detection systems in-line. Early IPS ... Read More
Suppose we have four numbers n1, n2, k1 and k2. Consider there are 2 boxes, first one has n1 balls and second one has n2 balls. Amal and Bimal are playing the game. In one move they can take from 1 to k1 balls and throw them out, similarly second one will take 1 to k2 balls in his move. Amal starts the game and they plays alternatively. The one who cannot play his move will lose the game. We have to find who will be the winner.So, if the input is like n1 = 2; n2 = 2; k1 ... Read More
The drop_duplicate() method in the pandas series constructor is used to remove the duplicate values from a series object. This method cleans the duplicate values and returns a series with modified rows, and it won’t alter the original series object. Instead, it will return a new one.One of the important parameters in the drop_duplicates() method is “Keep”, the default value of this parameter is “first” which keeps the first occurrence value and deletes the remaining. We can also specify Last and False values to the keep parameter.If keep=False, it will delete all duplicate values. Or if keep= “Last”, it deletes ... Read More
The main advantage of using the pandas package is analysing the data for Data Science and Machine Learning applications. In the process of analysing the data, deleting duplicate values is a commonly used data cleaning task.To remove duplicate values from a pandas series object, we can use the drop_duplicate() method. This method returns a series with deleted duplicate rows, and it won’t alter the original series object. Instead, it will return a new one.By using the inplace parameter, we can update the changes into the original series object by setting “inplace=True”.The other important parameter in the drop_duplicates() method is “Keep”. ...

To integrate a Hermite series, use the hermite.hermint() method in Python. The 1st parameter, c is an array of Hermite series coefficients. If c is multidimensional the different axis correspond to different variables with the degree in each axis given by the corresponding index. The 2nd parameter, m is an order of integration, must be positive. (Default: 1)The 3rd parameter, k is an integration constant(s). The value of the first integral at lbnd is the first value in the list, the value of the second integral at lbnd is the second value, etc. If k == [] (the default), all ... Read More
