The focus of infosec management is on people, which includes both security personnel and elements of the seta programme.

Integrity, confidentiality, and availability. The CIA Triad is a paradigm for information security that is designed to direct an organization's security practises and guidelines. Confidentiality, integrity, and availability are regarded as the three most important concepts in information security. Taking these three elements together within the "triad" framework can influence the formulation of business security policies.

The CIA triad has long been regarded as a model for information security. It is not a single doctrine with a single author. Rather, the model appears to have evolved over time, with roots as old as modern computing and concepts drawn from a variety of sources. Ben Miller, vice president of Dragos, appears to be one of the few people who has investigated the triad's origins. He wrote a blog post about its origins 11 years ago and was unable to find a single source.

A) An adjacency list is a data structure used to represent a graph. It consists of an array of vertices, where each vertex has a head pointer to a linked list of its neighboring vertices. Each node in the linked list represents an edge connecting the vertex to one of its neighbors. The advantage of an adjacency list is that it can represent sparse graphs efficiently, using only O(|V| + |E|) space, where |V| is the number of vertices and |E| is the number of edges in the graph.

A hash table using chaining, on the other hand, is a data structure used to implement a dictionary or map. It consists of an array of buckets, where each bucket contains a linked list of key-value pairs. To store a value with a given key, the key is first hashed to determine the index of the corresponding bucket, and then the key-value pair is inserted at the head of the linked list in that bucket. The advantage of a hash table using chaining is that it can support efficient lookup, insertion, and deletion of key-value pairs, even for large dictionaries.

The main difference between these data structures is that an adjacency list is designed specifically for representing graphs, while a hash table using chaining is a general-purpose data structure for implementing dictionaries. While both data structures use linked lists to represent their elements, the interpretation and usage of these linked lists is different: in an adjacency list, each linked list represents the neighbors of a vertex, while in a hash table using chaining, each linked list represents the set of key-value pairs that hash to the same bucket.

B) If a graph is weighted, it means that each edge has a weight or cost associated with it. In this case, the adjacency list data structure will be affected, since each node in the edge list will need to store not only the ID of the neighboring vertex, but also the weight of the corresponding edge. This can be done by adding a third field to each edge node, which stores the weight. Alternatively, the edge list can be represented as a linked list of structs, where each struct contains two fields: the ID of the neighboring vertex and the weight of the corresponding edge.

The vertex list in the adjacency list data structure will not be affected by the weights of the edges, since it only stores information about the vertices themselves, not their relationships with other vertices. However, if the graph is directed, the vertex list may need to store both incoming and outgoing edge lists for each vertex, since the set of neighbors may be different depending on the direction of the edges.

"The unique_ptr is the sole owner of a piece of dynamically allocated memory" is true. A unique_ptr ensures that the memory is managed correctly, and it automatically deallocates the memory when the unique_ptr goes out of scope. As the sole owner, the unique_ptr prevents multiple pointers from owning the same memory, avoiding issues such as double deletion or memory leaks.

A unique_ptr is a container for a raw pointer, which the unique_ptr is said to own. A unique_ptr explicitly prevents copying of its contained pointer (as would happen with normal assignment), but the std::move function can be used to transfer ownership of the contained pointer to another unique_ptr. A unique_ptr cannot be copied because its copy constructor and assignment operators are explicitly deleted.

Explanation:

a) Low cost, typically 1-2 I/Os. b) Variable cost based on index selectivity and matching records. c) Variable cost based on index selectivity and matching records.

Explanation:

To determine the minimum cost of each query with any number of secondary indexes available, we need to consider the access paths that can be used to retrieve the required data.

a) For the query "select count(*) from employees where name = ‘John Smith’", we can create a secondary index on the "name" attribute. With this index, we can perform a single index lookup to retrieve all the records with the name "John Smith" and count the number of records returned. The cost of this query would be equal to the cost of a single index lookup, which is typically around 1-2 I/Os.

b) For the query "select avg(salary) from employees where name = ‘John Smith’", we can create a secondary index on the "name" attribute and another index on the "salary" attribute. With these indexes, we can perform a multi-index lookup to retrieve all the records with the name "John Smith" and compute the average salary. The cost of this query would be equal to the cost of a multi-index lookup, which depends on the selectivity of the indexes and the number of matching records.

c) For the query "select count(*) from employees where birthdate < ‘1-1-1980 00:00’", we can create a secondary index on the "birthdate" attribute. With this index, we can perform a range scan to retrieve all the records with a birthdate before "1-1-1980 00:00" and count the number of records returned. The cost of this query would be equal to the cost of a range scan, which depends on the selectivity of the index and the number of matching records.

In general, the cost of a query with secondary indexes depends on the selectivity of the indexes, the number of matching records, and the complexity of the access path required to retrieve the required data. By carefully choosing the right indexes and optimizing the query execution plan, we can minimize the cost of each query and improve the overall performance of the database system.
