exercise 1


Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: It secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password

Network security issues involve maintaining network integrity, preventing unauthorized users from infiltrating the system (viewing/stealing sensitive data, passwords, etc.), and protecting the network denial of service attacks.These issues are greatly magnified as a networks increases in size. Larger networks are more susceptible to attack because they offer more vulnerable points at which intruders can gain access. More users, more passwords, and more hardware mean more places a hacker can try to get in.


Defense against these problems include using firewalls and proxies, installing strong antivirus software, deploying strict password policies, making use of network analysis software, physically securing computer networking assets, and invoking procedures that compartmentalize a large network with internal boundaries.
