Umbrella to protect communication networks and devices connected to the network

Throughout the period, from the first sector launcher virus to sophisticated and sophisticated threats targeting organizations, users, and even governments, information has been targeted.

A security expert protect has no choice but to learn about threats to routers, switches, wireless networks, and more importantly the systems used to prevent or trap hackers. 

For end users or consumers, a network is the only tool they use to do their job, so if an organization’s information security management team thinks the organization’s communications infrastructure has no problems and no matter what security issues, weekly or monthly reviews Failure to do so will suddenly lead to an unexpected attack

that information theft or loss of information records will be only part of the deleterious consequences of this failure.

Confidentiality, accessibility, and integrity are the three basic tenets of network security; more precisely, the news that is spread about malware or attacks on an organization’s network in the media are all centered around these three.

Attacks that attempt to violate the above three principles. The principle of confidentiality refers to data protection on the network.

 Data on the network should be out of reach of unauthorized users and should not be allowed to allow unauthorized access. In this context, cryptographic algorithms help us to protect data.

 The principle of integrity refers to the fact that changes to events should only be performed by authorized users.

If the data that must be transmitted over a network is corrupted, the data integrity principle is violated.

The principle of accessibility refers to the fact that data should be accessible to authorized users without problems. Any factor that disrupts the accessibility principle and disrupts access to network-based services, systems, and data can cause serious financial losses.

In order to properly protect an organization’s communications infrastructure, a computer network security expert has to upgrade his knowledge of the basics of computer network security, different security terminologies, different types of attacks and security tools.

The greater the level of knowledge a computer network security expert has, the faster it is in detecting a timely attack and can take appropriate action at the right time.

 Naturally,

a computer network security expert is required to have sufficient information about the underlying and important issues of networks.

For example,

he should know how different layers of the OSI or TCP / IP model work and what command line tools and commands are use to check the status of networks. That’s why people in charge of securing computer networking in connection with networking issues have knowledge of the CCNA R&S level.

The security of computer networks is just as important as mastering the implementation of networks. Accordingly, we have assigned the special issue of Network Magazine No. 218 to the issue of security in computer networks.

Computers have been helping humans develop for over half a century. As these systems become more pervasive and sophisticated, the threats around them also increase. These smart CPUs are always threatened by people trying to interfere with organizations’ operations and stop them.

Throughout the period,

from the first sector launcher virus to sophisticated and sophisticated threats targeting organizations, users, and even governments, information has been targeted. Today’s organizations face quite complex threats, each posing a real threat to an organization.

A successful and calculate hacker attack is execute on the basis of four end-user factors

(employees of an organization), malware kits,

software breaches and misconfiguration of network equipment.

 Reports released by companies such as Kaspersky, McAfee, and others show that every hour a new threat emerges that forces security companies to be fully prepared to face that threat and protect computers and networks.

A security expert has no choice but to learn about threats to routers, switches, wireless networks, and more importantly the systems used to prevent or trap hackers.

For end users or consumers, a network is the only tool they use to do their job,

so if an organization’s information security management team thinks

the organization’s communications infrastructure has no problems and no matter what security issues,

weekly or monthly reviews Failure to do so will suddenly lead to an unexpected attack

that information theft or loss of information records will be only part of the deleterious consequences of this failure.
